Plus Therapeutics, Inc. Announces Read Out of Type B Meeting with the FDA with Goal of Accelerating Approval of REYOBIQ™? for Leptomeningeal Metastases Plus Therapeutics, Inc. announced the completion of a Type B meeting with the U.S. Food and Drug Administration (FDA) on next steps on REYOBIQ pivotal trial strategy for leptomeningeal metastases (LM). The meeting resulted in constructive discussion with the FDA regarding key elements of the potential pivotal study design for REYOBIQ in LM. Plus intends to incorporate the FDA's feedback in the current dose optimization trial and seek alignment with the FDA on a revised protocol, likely later this year. The company's goal is to be ready for a potential pivotal trial following completion of the current dose optimization trial and, ultimately, work towards the potential approval of REYOBIQ for patients affected by LM. Highlights of FDA responses to the Company's key enquiries: Accelerated approval - FDA indicated that accelerated approval may be appropriate for the LM indication, but there are insufficient data to support the use of circulating tumor cells (CTCs) as an intermediate clinical endpoint. FDA and Plus discussed that additional steps would be necessary to validate CTCs as a surrogate endpoint to potentially support other future applications. Primary and key endpoints - FDA recommended that the study evaluate an endpoint with established clinical benefit, such as overall survival, while encouraging further study of patient reported outcomes and neurological function as endpoints that could potentially support a marketing application. FDA and Plus aligned that CTCs could be considered for use as a secondary endpoint. Trial design and comparator group - FDA and Plus discussed a randomized controlled trial design approach and that the study may include an intrathecal chemotherapeutic as a comparator, as well as approaches to standardize the comparator and any additional interventions available under the trial protocol. Treated populations - FDA conveyed it may be reasonable to incorporate multiple histologies (i.e., multiple underlying disease etiologies) in a single trial. Annuncio • Dec 04

The Company reported stockholders’ equity (deficit) of ($23,641,000) in its Quarterly Report on Form 10-Q for the period ended March 31, 2025, and, as a result, did not satisfy the Minimum Stockholders’ Equity Requirement pursuant to Listing Rule 5550(b)(1). As a result, the Staff determined to delist the Company’s securities from Nasdaq, unless the Company timely requests an appeal of the Staff’s determination to a Hearings Panel (the “Panel”), pursuant to the procedures set forth in the Nasdaq Listing Rule 5800 Series. The Company must request a hearing no later than 4:00 p.m. Eastern Time on June 10, 2025. The Company plans to request a hearing before the Panel to appeal the June 3 Letter and to address all outstanding matters, including compliance with the Minimum Stockholders’ Equity Requirement, which hearing date has not been set as of the date of this Current Report on Form 8-K (this “Form 8-K”). While the appeal process is pending, the suspension of trading of the Company’s common stock, par value $0.001 per share (the “Common Stock”), will be stayed and the Common Stock will continue to trade on the Nasdaq Capital Market until the hearing process has concluded and the Panel issues a written decision. The Company has been informed that hearings are typically scheduled to occur approximately 30-45 days after the date of the hearing request. There can be no assurance, however, that the Panel will grant the Company’s request for continued listing or that the Company will be able to demonstrate compliance with Nasdaq Listing Rule 5550(b)(1) within any additional compliance period that may be granted by the Panel.

Plus Therapeutics Receives Non-Compliance Letter from Nasdaq Regarding Minimum Bid Requirement On May 16, 2025, Plus Therapeutics, Inc. (the Company") received notice from The Nasdaq Stock Market LLC (Nasdaq") that, because the closing bid price for the Company's common stock has fallen below $1.00 per share for 30 consecutive business days, the Company no longer complies with the minimum bid price requirement pursuant to Nasdaq Listing Rule 5550(a)(2) (the Minimum Bid Requirement"). Nasdaq's notice has no immediate effect on the listing or trading of the Company's common stock. Pursuant to Nasdaq Listing Rule 5810(c)(3)(A), the Company is provided an initial compliance period of 180 calendar days, or until November 12, 2025, to regain compliance with the Minimum Bid Requirement. To regain compliance, the closing bid price of the Company's common stock must meet or exceed $1.00 per share for a minimum of 10 consecutive business days prior to November 12, 2025. If the Company does not achieve compliance with the Minimum Bid Requirement by November 12, 2025, the Company may be eligible for an additional 180 calendar days to regain compliance. To qualify, the Company would be required to meet the continued listing requirement for market value of publicly held shares and all other Nasdaq initial listing standards, with the exception of the Minimum Bid Requirement, and provide written notice of its intention to cure the minimum bid price deficiency during the second compliance period by effecting a reverse stock split if necessary.

Plus Therapeutics, Inc. Presents New Data Highlighting Clinical Benefit and Safety of REYOBIQ in the ReSPECT-LM Clinical Trial for Patients with Leptomeningeal Metastases Plus Therapeutics, Inc. announced the online availability of new data on its lead compound REYOBIQ™ (rhenium Re186 obisbemeda) in an abstract for both an oral presentation and a poster to be presented at the Nuclear Medicine and Neurooncology conference to be held May 9-10, 2025 in Vienna, Austria. The abstract, titled, "Rhenium Obisbemeda (REYOBIQ) in Leptomeningeal Metastases," highlights additional data from the Company's completed Phase 1 ReSPECT-LM dose escalation trial demonstrating a dose dependent increase in the average absorbed dose to the cranial and spinal subarachnoid space reaching 253Gy in Cohort 5. Neuroimaging response data was available for 16 patients as of the data cutoff with five of those (31%) showing a partial response. An additional seven patients showed stable disease by neuroimaging through day 112 for a Clinical Benefit Rate (complete response + partial response + stable disease) of 75%. Additionally, a clinical response based on the physician evaluation showed a decrease in disease findings in two of 14 evaluable patients (14%) and 10 patients showed stable findings through day 112 for an 86% Clinical Benefit Rate. The incidence of LM is on the rise, partly because cancer patients are living longer and partly because many standard chemotherapy cannot reach sufficient concentrations in the spinal fluid to kill the tumor cells, yet there are no FDA-approved therapies specifically for LM patients, who often succumb to this complication within weeks to several months, if untreated. REYOBIQ™™ is being evaluated for the treatment of recurrent gllioblastoma and leptomeningeal metastases in the ReSPECT-GBM and ReSPECT-LM clinical trials. Annuncio • Apr 01

Plus Therapeutics Introduces REYOBIQ, FDA- Accepted Proprietary Name for Lead Drug Candidate Plus Therapeutics, Inc. announced the U.S. Food and Drug Administration (FDA) has previously accepted the Company's new proprietary name, REYOBIQ, for its lead therapeutic candidate. A request for proprietary name review for REYOBIQ must be submitted once the marketing application (NDA) is submitted. All communications regarding the USAN-adopted and INN-recommended rhenium Re186 obisbemeda generic name will now utilize the proprietary name REYOBIQ. REYOBIQ (rhenium Re 186 obisbemeda) is a novel injectable radiotherapy specifically formulated to deliver direct targeted high dose radiation in CNS tumors in a safe, effective, and convenient manner to optimize patient outcomes. REYOBIQ has the potential to reduce off target risks and improve outcomes for CNS cancer patients, versus currently approved therapies, with a more targeted and potent radiation dose. Rhenium-186 is an ideal radioisotope for CNS therapeutic applications due to its short half-life, beta energy for destroying cancerous tissue, and gamma energy for real-time imaging. REYOBIQ is being evaluated for the treatment of recurrent glioblastoma and leptomeningeal metastases in the ReSPECT-GBM and ReSPECT-LM clinical trials. ReSPECT-GBM is supported by an award from the National Cancer Institute (NCI), part of the U.S. National Institutes of Health (NIH), and ReSPECT-LM is funded by a three-year $17.6 million grant by the Cancer Prevention & Research Institute of Texas (CPRIT).

Plus Therapeutics, Inc. Receives U.S. FDA Orphan Drug Designation for Rhenium (186Re) Obisbemeda for the Treatment of Leptomeningeal Metastases in Patients with Lung Cancer Plus Therapeutics, Inc. announced that the U.S. Food and Drug Administration (FDA) has granted Orphan Drug Designation (ODD) to Rhenium (186Re) Obisbemeda for the treatment of leptomeningeal metastases (LM) in patients with lung cancer. The FDA grants ODD status to an investigational drug or biologic intended to prevent, diagnose, or treat a rare disease or condition affecting fewer than 200,000 people in the United States. ODD provides certain benefits to drug developers, including seven potential years of market exclusivity, tax credits for qualified clinical trials, and exemptions from significant regulatory fees, including the Prescription Drug User Fee Act (PDUFA) charge of $4.3 million in 2025 and the Pediatric Research Equity Act (PREA) requirements. The Company is now advancing a Phase 2 single-dose expansion trial and a Phase 1 multiple-dose trial while actively engaging the FDA to define the optimal pivotal trial strategy. The incidence of LM is on the rise, partly because cancer patients are living longer and partly because many standard chemotherapy cannot reach sufficient concentrations in the spinal fluid to kill the tumor cells, yet there are no FDA-approved therapies specifically for LM patients, who often succumb to this complication within weeks to several months, if untreated.

New major risk - Revenue and earnings growth Earnings are forecast to decline by an average of 2.5% per year for the foreseeable future. This is considered a major risk. Ultimately, shareholders want to see a good return on their investment and that generally comes from sharing in the company's profits. If profits are expected to decline, then in most cases the share price will decline over time as well. In addition, if the company pays dividends it will also likely need to reduce or cut them, striking a dual blow to total shareholder returns. Currently, the following risks have been identified for the company: Major Risks Less than 1 year of cash runway based on free cash flow trend (-US$11m free cash flow). Share price has been highly volatile over the past 3 months (15% average weekly change). Negative equity (-US$7.6m). Earnings are forecast to decline by an average of 2.5% per year for the foreseeable future. Market cap is less than US$10m (€7.06m market cap, or US$7.43m). Minor Risks Currently unprofitable and not forecast to become profitable over next 3 years (US$46m net loss in 3 years).

Plus Therapeutics Reports ReSPECT-GBM Clinical Trial Update at the 2024 Congress of Neurological Surgeons Annual Meeting Plus Therapeutics, Inc. presented an update on the ongoing ReSPECT-GBM Phase 1/2 clinical trial, evaluating the Company’s lead asset Rhenium (186Re) Obisbemeda for the treatment of recurrent glioblastoma. The data were presented at the 2024 Congress of Neurological Surgeons (CNS) Annual Meeting on September 30, 2024, in Houston, Texas. The presentation, titled “Treatment of Recurrent Glioblastoma (rGBM) via Convection Enhanced Delivery (CED) with Rhenium (186Re) Obisbemeda (Rhenium-186 Nanoliposome, 186RNL): ReSPECT-GBM Phase 1/2 Trial Update” was delivered by lead investigator and neurosurgeon John Floyd, M.D., Associate Professor and Chair of the Department of Neurosurgery at the University of Texas Health Science Center San Antonio. The data highlights the continued favorable safety profile and encouraging efficacy results of Rhenium (186Re) Obisbemeda in a patient population with historically poor prognosis. ReSPECT-GBM is a first-in-human, open-label, Phase 1/2 study investigating feasibility, dose escalation, and critical convection enhanced delivery (CED) parameters to determine the maximum tolerated dose (MTD), maximum feasible dose (MFD), safety, and potential efficacy of Rhenium (186Re) Obisbemeda in recurrent adult glioma (IND 116117). Key Highlights from the ReSPECT-GBM Phase 1/2 Trial Update: 42 total patients have enrolled thus far at 3 sites and with 19/42 patients having been treated to date at the recommended Phase 2 dose (22.3 mCi in 8.8 mL) in tumors of approximately 20 cm3 or less. All Phase 2 patients have recurrent, histologically confirmed glioblastoma; 1 recurrence, bevacizumab naïve, single tumor of approximately 20 cm3 or less (small-to-medium sized tumors). Average tumor size in Phase 2 was 7.5 mL (range 0.9-22.8 mL). Increases in absorbed dose correlated with specific drug delivery parameters such as infused dose and volume, maximal convection flow rate, and number of catheters. Rhenium (186Re) Obisbemeda continues to show a favorable safety profile in the 42 enrolled patients; one dose-limiting toxicity (hemiplegia) has been reported, which was observed in Cohort 8 (41.5 mCi and 16.3 mL). In Phase 2, most adverse events (AEs) were mild (73.5%) or moderate (18.8%), and largely unrelated (37.7%), or unlikely related (27.1%) to the drug. Of the 9 severe adverse events (SAEs), only 2 were related to the study drug. Average absorbed radiation dose to the tumor in Phase 2 was 300 Gy (n=18, 1 patient still under analysis). To date, 88.9% of Phase 2 patients met key CED drug delivery parameters shown to correlate with overall survival, achieving a tumor absorbed dose >100 Gy and radiation coverage of >70%. 29/42 patients treated thus far participated in the Phase 1 dose escalation phase of the trial (Note: as per protocol, 6/42 patients were included in both the Phase 1 and Phase 2 trial arms and related analyses). Phase 1 dose-escalation increased administered doses from 1.0 mCi to 41.5 mCi and volumes from 0.66 mL to 16.3 mL. In terms of objective tumor response based on quantitative image analysis, a statistically significant reduction in tumor volume rate change was seen in tumors receiving > 100 Gy absorbed dose (n=11 patients analyzed to date, p<0.005). Sufficient tumor coverage correlated with tumor control, while regrowth occurred outside treated areas. Annuncio • Sep 09

New major risk - Share price stability The company's share price has been highly volatile over the past 3 months. It is more volatile than 90% of German stocks, typically moving 10% a week. This is considered a major risk. Share price volatility increases the risk of potential losses in the short-term as the stock tends to have larger drops in price more frequently than other stocks. It may also indicate the stock is highly sensitive to market conditions or economic conditions rather than being sensitive to its own business performance, which may also be inconsistent. Currently, the following risks have been identified for the company: Major Risks Share price has been highly volatile over the past 3 months (10% average weekly change). Negative equity (-US$4.8m). Shareholders have been substantially diluted in the past year (129% increase in shares outstanding).

New major risk - Revenue and earnings growth Earnings are forecast to decline by an average of 0.2% per year for the foreseeable future. This is considered a major risk. Ultimately, shareholders want to see a good return on their investment and that generally comes from sharing in the company's profits. If profits are expected to decline, then in most cases the share price will decline over time as well. In addition, if the company pays dividends it will also likely need to reduce or cut them, striking a dual blow to total shareholder returns. Currently, the following risks have been identified for the company: Major Risks Negative equity (-US$1.3m). Earnings are forecast to decline by an average of 0.2% per year for the foreseeable future. Shareholders have been substantially diluted in the past year (72% increase in shares outstanding).

Plus Therapeutics, Inc. Announces Validation & Clinical Implementation of Csf-01 Leptomeningeal Cancer Cell Diagnostic Plus Therapeutics, Inc. announced it has successfully completed key validation testing and implementation of its tumor cell enumeration assay, known as CSF-01, to be used initially as an exploratory endpoint in its ReSPECT-LM clinical trials. Plus’ CSF-01 cancer cell enumeration test is an exploratory endpoint in the ReSPECT-LM Phase 1 trial that has shown promise in the trial’s early cohorts. In Phase 1/Part A of the ReSPECT-LM trial presented at the 2023 SNO/ASCO Meeting in San Francisco, Plus showed an average 53% reduction in CSF tumor cells 28 days after a single intrathecal administration of rhenium (186Re) obisbemeda in patients with LM. On December 12, 2023, Plus announced its partnership with K2bio (Houston, Texas) to implement Plus’ CSF-01 diagnostic for LM cancers in the ReSPECT-LM trials. While validated for use in Plus’ clinical development programs, full Clinical Laboratory Improvement Amendments (CLIA) certification is not anticipated until 2025. The ReSPECT-LM trial, including support for CSF-01 testing, is currently receiving grant funding from the Cancer Prevention and Research Institute of Texas (CPRIT). The FORSEE trial was performed by the original developer and licensor of CSF-01 and is a multi-center, prospective clinical trial enrolling patients with breast or non-small cell lung cancer (NSCLC) who have suspicious or confirmed LM. If the FORSEE data is positive, the company intend to work toward increasing commercial reimbursement for the CLIA-certified test and explore partnerships to maximize diagnostic utilization for the broader CNS cancer space. About Leptomeningeal Metastases (LM): LM is a rare complication of cancer in which the primary cancer spreads to the cerebrospinal fluid (CSF) and leptomeninges surrounding the brain and spinal cord. All malignancies originating from solid tumors, primary brain tumors, or hematological malignancies have this LM complication potential with breast cancer as the most common cancer linked to LM, with 3-5% of breast cancer patients developing LM. Additionally, lung cancer, GI cancers, and melanoma can also spread to the CSF and result in LM. LM occurs in approximately 5% of people with cancer and is usually terminal, with a 1-year and 2-year survival of just 7% and 3%, respectively. The incidence of LM is on the rise, partly because cancer patients are living longer and partly because many standard chemotherapies cannot reach sufficient concentrations in the spinal fluid to kill the tumor cells. Yet, there are no FDA-approved therapies specifically for LM patients, who often succumb to this complication within weeks to several months if untreated. About Rhenium (186Re) obisbemeda: Rhenium (186Re) obisbemeda is a novel injectable radiotherapy specifically formulated to deliver directly targeted high-dose radiation in CNS tumors in a safe, effective, and convenient manner to optimize patient outcomes. Rhenium (186Re) obisbemeda has the potential to reduce off-target risks and improve outcomes for CNS cancer patients, versus currently approved therapies, with a more targeted and potent radiation dose. Rhenium-186 is an ideal radioisotope for CNS therapeutic applications due to its short half-life, beta energy for destroying cancerous tissue, and gamma energy for real-time imaging. Rhenium (186Re) obisbemeda is being evaluated for the treatment of recurrent glioblastoma and leptomeningeal metastases in the ReSPECT-GBM and ReSPECT-LM clinical trials. ReSPECT-GBM is supported by an award from the National Cancer Institute (NCI), part of the U.S. National Institutes of Health (NIH), and ReSPECT-LM is funded by a three-year $17.6M grant by the Cancer Prevention & Research Institute of Texas (CPRIT).

Plus Therapeutics, Inc. Reports New Interim ReSPECT-GBM Phase 2 Trial Data at the Society for NeuroOncology Annual Meeting Plus Therapeutics, Inc. announced positive data from the ongoing ReSPECT-GBM Phase 2 trial evaluating the Company’s lead radiotherapeutic, rhenium (186Re) obisbemeda, for the treatment of recurrent glioblastoma (rGBM) at the Society for NeuroOncology (SNO) 28th Annual Meeting held November 15-19, 2023 in Vancouver, Canada. Key Highlights from the ReSPECT-GBM Phase 2 Trial: ReSPECT-GBM is an ongoing, first-in-human, open-label, Phase 1/2 study investigating dose escalation and other delivery parameters (i.e., number of catheters (1-5), infusion rates, drug volumes, and drug concentrations) to determine the maximum tolerated dose (MTD), maximum feasible dose (MFD), safety, and efficacy of rhenium (186Re) obisbemeda in recurrent adult glioma (IND 116117). The primary objective of the Phase 2 study is to assess overall survival (OS) following rhenium (186Re) obisbemeda administration. As of November 14, 2023, 15 patients with rGBM have been treated with rhenium (186Re) obisbemeda at a dose of 22.3 mCi delivered directly to the tumor by Convection Enhanced Delivery (CED). In 15 treated patients, mOS is 13 months (95% CI 5 months). Currently, 9 out of the 15 treated patients remain alive. Median PFS is 11 months (95% CI 6-11 months). The average percent of treated tumor across all 15 patients was 87.2% at 120 hours, with 13/15 patients receiving greater than or equal 70% tumor volume coverage by the drug and =100 Gy absorbed dose to the tumor. Advanced longitudinal imaging analysis supports the observed efficacy signal of rhenium (186Re) obisbemeda. Rhenium (186Re) obisbemeda continues to be generally safe and well tolerated, consistent with data accumulated in the Phase 1 trial. New Risk • Nov 05
New major risk - Shareholder dilution The company's shareholders have been substantially diluted in the past year. Increase in shares outstanding: 102% This is considered a major risk. Shareholder dilution occurs when there is an increase in the number of shares on issue that is not proportionally distributed between all shareholders. Often due to the company raising equity capital or some options being converted into stock. All else being equal, if there are more shares outstanding then each existing share will be entitled to a lower proportion of the company's total earnings, thus reducing earnings per share (EPS). While dilution might not always result in lower EPS (like if the company is using the capital to fund an EPS accretive acquisition) in a lot cases it does, along with lower dividends per share and less voting power at shareholder meetings. Currently, the following risks have been identified for the company: Major Risks Less than 1 year of cash runway based on free cash flow trend (-US$13m free cash flow). Share price has been highly volatile over the past 3 months (21% average weekly change). Earnings are forecast to decline by an average of 19% per year for the foreseeable future. Shareholders have been substantially diluted in the past year (102% increase in shares outstanding). Market cap is less than US$10m (€6.75m market cap, or US$7.24m).

Plus Therapeutics, Inc. Reports Positive Interim Updates from Two Respect Clinical Trials at SNMMI Annual Meeting Plus Therapeutics, Inc. reported positive interim updates from the ReSPECT-GBM and ReSPECT-LM clinical studies evaluating the Company’s lead radiotherapeutic, rhenium ( 186 Re) obisbemeda, for the treatment of recurrent glioblastoma (rGBM) and leptomeningeal metastases (LM) at the Society of Nuclear Medicine & Molecular Imaging (SNMMI) Annual Meeting, which took place June 24-27, 2023 in Chicago, Illinois. An oral presentation titled, Safety and Feasibility Results from a Phase 1/2 Clinical Trial of 186RNL (Rhenium-186 Nanoliposome) (186Re) Obisbemeda in Recurrent Glioma: The ReSPECT-GBM Trial [P988], brief highlights include: Data from 21 patients in the Phase 1 trial used to support the recommended Phase 2 trial dose for patients with tumor volumes =20 mL was presented. A single dose of rhenium ( 186 Re) obisbemeda was generally safe and well-tolerated, with no dose-limiting toxicities and minimal systemic radiation exposure. The data demonstrates efficacy signals in a prognostically unfavorable patient population. The median overall survival (OS) in all 21 patients (including those receiving small radiation doses in early cohorts and five patients previously treated with Bevucizamab) was 11 months or a 38% increase in OS versus a median OS of approximately 8 months for standard of care in rGBM. Median OS in patients receiving >100 Gy of absorbed radiation dose was 76 weeks (17 months) versus 22 weeks (6 months) for those receiving <100 Gy (p=0.0002). Increased absorbed radiation dose and percent tumor volume treated correlates with improvement in overall survival, specifically: For each 100 Gy increase of Total Dose in Distribution Volume, the risk of death decreases by 45.6% (p=0.003). For each 10% increase in the Ratio of Treated to Total Tumor Volume, the risk of death decreases by 66.9% (p=0.002). A poster presentation titled, Preliminary Clinical Data in The Phase 1/2a Dose Escalation Trial of 186RNL (Rhenium-186 Nanoliposome) (186Re) Obisbemeda in Leptomeningeal Metastases (LM): The ReSPECT-LM Trial [P978], includes data that showed: Interim results from 10 patients in the Phase 1 trial show a single treatment with rhenium (186Re) obisbemeda decreased cerebrospinal fluid (CSF) tumor cell count and was well-tolerated in patients with LM. Rhenium ( 186 Re) obisbemeda doses administered through an intraventricular catheter (Ommaya reservoir) showed prompt, complete and durable distribution throughout the CSF through Day 7. A single rhenium ( 186 Re) obisbemeda administered dose between 6.6 mCi and 26.4 mCi achieved absorbed doses of up to 88.98 Gy to the ventricles and cranial subarachnoid space. No dose limiting toxicities were observed and safety observations were generally minor and resolved. Phase 1/Part B, for continued dose escalation (Cohorts 4-7), will open following review by the U.S. Food and Drug Administration, and repeated dosing will be explored. An expansion in Cohort 3 is currently enrolling eligible patients. A full update will be provided at the SNO/ASCO CNS Cancer Conference in August 10-12, 2023. Annuncio • Feb 15

The trial is supported by an award from the National Cancer Institute (NCI), part of the U.S. National Institutes of Health (NIH). GBM affects approximately 14,490 patients annually in the U.S. and is the most common and lethal form of brain cancer. The average life expectancy with GBM is less than 24 months, with a one-year survival rate of 40.8% and a five-year survival rate of only 6.9%. There is no clear standard of care for recurrent GBM and even the few currently approved treatments provide only marginal survival benefit and are associated with significant side effects, which limit dosing and prolonged use. Approximately 90% of patients experience GBM tumor recurrence at or near the original tumor location, yet there are no FDA-approved treatments in the recurrent or progressive setting that can significantly extend a patient’s life. Rhenium (186Re) obisbemeda is a novel injectable radiotherapy specifically formulated to deliver highly targeted high dose radiation in CNS tumors in a safe, effective and convenient manner to optimize patient outcomes. Rhenium (186Re) obisbemeda has the potential to reduce risks and improve outcomes for CNS cancer patients, versus currently approved therapies, with a more targeted and potent radiation dose. Rhenium is an ideal radioisotope for CNS therapeutic applications due to its short half-life, beta energy for destroying cancerous tissue and gamma energy for live imaging. Annuncio • Nov 29

Plus Therapeutics Provides Updates on ReSPECT™ Clinical Trials Plus Therapeutics, Inc. presented data from two ongoing clinical trials evaluating the Company’s lead investigational targeted radiotherapeutic, rhenium (186Re) obisbemeda, in recurrent glioblastoma (GBM), leptomeningeal metastases (LM), as well as clinical trial plans for pediatric brain cancer at the 27th Annual Scientific Meeting and Education Day of the Society for Neuro-Oncology (SNO). The oral presentation titled, Report of the ReSPECT-GBM Phase 1/2a Dose Escalation Trial of Rhenium-186 NanoLiposome (186RNL) in Recurrent Glioma via Convection Enhanced Delivery (CED) & Planned Phase 2b Trial [RADT-20], included the following key findings: In 24 patients with recurrent glioblastoma, a single dose of rhenium (186Re) obisbemeda was administered in the dose escalation phase, (range: 1.0 mCi/0.66 mL to 31.2 mCi/12.3 mL), achieving up to 740 Gray (Gy) of absorbed radiation dose to the tumor. Between one to four intracranial CED catheters have been placed in each patient and there have been no dose limiting toxicities and a good safety profile has been observed.A statistically significant improvement in overall survival correlated with both the average absorbed dose of radiation to the tumor and the percent volume of tumor treated, specifically: A 100 Gy increase in the absorbed dose correlated with a 35.7% decrease in the risk of death (p=0.003, Cox methods hazard ratios = 0.643). A 1% increase in tumor volume treated is associated with a 4.5% decrease in the risk of death (p=0.002, Cox methods hazard ratios = 0.955). A recommended Phase 2 dose of 22.3 mCi in 8.8 mL is being studied for tumor volumes of 20 mL or less and is expected to enroll up to an additional 31 patients. Continued dose escalation will be performed to assess the potential to treat tumors larger than 20 mL. The Company’s second oral presentation titled, Preclinical Data and Initial Clinical Experience in the Phase 1/2a Dose Escalation Trial of Rhenium-186 Nanoliposome (186RNL) in Leptomeningeal Metastases [LM]: the ReSPECT-LM Trial [CTNI-02], highlighted data from the first two cohorts which demonstrates the potential of rhenium (186Re) obisbemeda to treat LM: As single rhenium (186Re) obisbemeda dose administered through an intraventricular catheter (Ommaya reservoir) at 6.6 mCi in 5.0 mL in Cohort 1 achieved absorbed doses of 18.7 to 29.0 Gy to the ventricles and cranial subarachnoid space, which was well tolerated with no treatment-related adverse events of greater than grade 1. All four patients treated to date in Cohorts 1 and 2 were observed to have prompt and complete rhenium (186Re) obisbemeda distribution throughout the cerebrospinal fluid (CSF) subarachnoid space that was durable to 28 days. All patients showed a decreased CSF tumor cell count by microfluidic chamber assay after treatment, ranging from 46% to 92%. Board Change • Nov 16

Plus Therapeutics Presents Positive Phase 1 Data from ReSPECT-GBM Clinical Trial at the European Society for Medical Oncology Congress 2022 Plus Therapeutics, Inc. announced Phase 1 data from the ReSPECT-GBM Phase 1/2a dose escalation clinical trial evaluating the Company’s lead investigational targeted radiotherapeutic, Rhenium-186 NanoLiposome (186RNL), in recurrent glioblastoma (GBM) in an oral presentation at the European Society for Medical Oncology (ESMO) Congress 2022, being held September 9-13, 2022 in Paris, France. The oral presentation titled, The ReSPECT-GBM Phase 1/2a Dose Escalation Trial of Rhenium-186 NanoLiposome (186RNL) in Recurrent Glioma via Convection Enhanced Delivery (CED) & Planned Phase 2b Trial, reviews data from the Phase 1 ReSPECT-GBM trial which evaluated 23 adult patients with recurrent GBM across 8 cohorts of increasing dose and treated over a seven-year period. Key findings include: No dose-limiting toxicities (DLT) have been observed and the procedure is very well tolerated with a strong safety profile. Minimal systemic radiation has been observed and the majority of adverse events have been mild or moderate and considered causally unrelated to the procedure. Improved median overall survival (OS) rates correlated with the absorbed tumor radiation dose. When patients were stratified based on receipt of either a therapeutic or a subtherapeutic absorbed dose of radiation to the tumor, a statistically significant improvement in survival was observed. Specifically, patients receiving a therapeutic absorbed radiation dose (>100 Gray) had a median OS of 22.9 (95% CI of 8.8-42.3) months compared to those receiving a subtherapeutic absorbed radiation dose (<100 Gray) whose median OS was 5.6 months (95% CI of 1.6-9.4). Currently, three patients remain alive, all in the therapeutic group. Feasibility to deliver up to at least 20 times more radiation to the tumor than the standard of care, external beam radiation therapy (EBRT). A maximum of 32.2 mCi in 12.3 mL of volume has been delivered in and near the tumors, and a maximum average absorbed dose of radiation of 740 Gray has been successfully administered in a single procedure. Average absorbed radiation dose to the tumor increased in latter dosing cohorts with greater administered doses of Re-186 ß-particle radiation, larger drug convection enhanced delivery (CED) infusate volumes, more catheters used (up to 4 versus 1), and higher convection flow rates. In cohorts 5 and later, 82% of patients received a therapeutic radiation dose of >100Gray. Single-photon emission computerized tomography and (SPECT)/CT scanning were used during treatment to compute tumor coverage and dosimetry. Post treatment imaging analyses, including MRI, relative cerebral blood volume (rCBV) analysis and treatment response assessment maps (TRAMs) correlated with a positive tumor response and confirmed the presence of pseudoprogression in patients with positive tumor responses. ReSPECT-GBM will proceed to an NIH and U.S. Food and Drug Administration (FDA) approved Phase 2 trial in the U.S. at the current non-DLT 186RNL dose and will expand exploring higher radiation doses in larger volumes to treat larger tumors. Additionally, two or more 186RNL administrations, if indicated, will be evaluated and reviewed with the FDA, as well as expanded safety, imaging and efficacy data to support a planned future registrational trial.

Plus Therapeutics, Inc. Presents Positive Data from Ongoing ReSPECT™ Clinical Trials at the Annual Conference on CNS Clinical Trials and Brain Metastases Plus Therapeutics, Inc. presented positive data from two ongoing clinical trials of its lead investigational drug, Rhenium-186 Nanoliposome (186RNL), in the treatment of recurrent glioblastoma (GBM) and leptomeningeal metastases (LM) at the 2022 Annual Conference on CNS Clinical Trials and Brain Metastases. The conference is co-sponsored by the Society for Neuro-Oncology (SNO) and the American Society of Clinical Oncology (ASCO) and is being held August 12-13, 2022 in Toronto, Canada. The oral presentation, titled Safety and Feasibility of Rhenium-186 Nanoliposome (186RNL) in Leptomeningeal Metastases Phase 1/2a Dose Escalation Trial [LOCL-04], demonstrated that the 186RNL dose administered through an intraventricular catheter at 6.6 mCi in 5.0 mL achieved absorbed doses of 18.7 to 29.0 Gy to the ventricles and cranial subarachnoid space, which was well tolerated with no treatment-related adverse events of greater than grade 1. Furthermore, all three patients in the cohort were observed to have prompt and complete 186RNL distribution throughout the cerebrospinal fluid (CSF) subarachnoid space that was durable past one week and very well tolerated. Importantly, all patients showed a decreased CSF cell count by microfluidic chamber assay after treatment, ranging from 65% to 92% which was also durable. Dr. Brenner also presented a poster titled, Safety and Feasibility of Rhenium-186 NanoLiposome (186RNL) in Recurrent Glioma: the ReSPECT™ Phase 1 Trial [LOCL-08], which demonstrated that in 23 subjects with recurrent GBM receiving a single administration of 186RNL, significant overall survival benefits were observed in those achieving an average absorbed radiation dose greater than 100 Gy to the tumor compared to those with less absorption. These findings suggest a correlation in increasing convected drug volume and radiation dose with improvement in overall survival of patients and to date, 80% of patients in cohorts 5-7 met the threshold of high levels of absorption greater than 100 Gy. Data show 186RNL treatment is safe and well-tolerated, with no adverse events (AEs) with outcome of death or discontinuations. At the time of the presentation, four patients remain alive. Cohort 7 of the trial, with an increased dose of 186RNL (31.2 mCi and infusate volume 12.3 mL), is currently enrolling. Annuncio • Jul 14

Plus Therapeutics Completes Enrollment of Cohort 1 Respect-Lm Phase 1/2A Trial Plus Therapeutics, Inc. announced the completion of enrollment in the first cohort of the ReSPECT-LM Phase 1/2a dose escalation clinical trial of Rhenium-186 NanoLiposome ((186) RNL) for the treatment of leptomeningeal metastases. The investigational drug, (186) RNL, is a proprietary nanoscale compound with a unique chelated radioisotope that is administered locally as a single dose via a conventional Ommaya reservoir. Rhenium-186 is a dual energy emitter (beta and gamma) with a short average path length for high precision, low dose rate that is safer for normal tissues, and high radiation density that overwhelms innate DNA repair mechanisms. The dual energy emission allows real time evaluation and monitoring of the (186) RNL administration. The ReSPECT-LM trial (NCT05034497) is a multicenter, sequential cohort, open-label, single dose, dose escalation Phase 1/2a study using a modified Fibonacci 3+3 study design. It will evaluate the maximum tolerated dose (MTD), maximum feasible dose (MFD), safety and efficacy of a single administration of (186) RNL via intraventricular catheter for LM following standard surgical, radiation and/or chemotherapy treatment. The primary endpoints of the study are the incidence and severity of adverse events/serious adverse events and dose limiting toxicities. Secondary endpoints include overall response rate, duration of response, progression free survival and overall survival. The ReSPECT-LM Phase 1/2a clinical trial follows preclinical studies in which tolerance to doses of (186) RNL as high as 1,075 Gy was shown in animal models with LM with no observed significant toxicity. Treatment led to marked reduction in tumor burden in two animal models of LM. In November 2021, the Company announced that the FDA granted Fast Track designation to (186) RNL for the treatment of LM. Fast Track designation confers several benefits to the drug development program including more frequent meetings with and written communication from FDA, eligibility for Accelerated Approval and Priority Review, if relevant criteria are met, and Rolling Review, which allows a drug company to submit completed sections of its New Drug Application (NDA) for review by FDA, rather than wait until every section of the NDA is completed before the entire application can be reviewed.

Plus Therapeutics Reports Positive Clinical Outcomes from ReSPECT-GBM Trial at the Society of Nuclear Medicine and Molecular Imaging 2022 Annual Meeting Plus Therapeutics, Inc. announced it will present positive data on its lead investigational drug, Rhenium-186 NanoLiposome (186RNL), from the Phase 1/2a ReSPECT™-GBM dose escalation clinical trial in patients with recurrent glioblastoma (GBM) during an oral presentation at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) 2022 Annual Meeting, on June 14 at 10:20 AM PT in Vancouver, British Columbia, Canada. According to the interim data, 186RNL delivered via convection enhanced delivery (CED) provides direct therapy with high radiation absorbed doses for local tumor control with minimal brain and whole-body radiation exposure. 186RNL’s tumor-killing effects were observed when greater than 100 Gy doses are delivered to greater than 80% of a tumor without dose-limiting toxicity. The presentation, titled “Rhenium-186-NanoLiposome (186RNL) in the treatment of relapse/recurrent glioblastoma (rGBM): a novel approach to cancer therapy,” outlines data from the ReSPECT-GBM trial, substantially funded by the U.S. National Institutes of Health/National Cancer Institute, which has thus far evaluated 24 adult patients with recurrent GBM across seven cohorts of increasing dose. To date, there have been no significant adverse events during the dose escalation. The company expects to initiate a Phase 2/registrational trial of 186RNL in patients with recurrent GBM by the end of 2022. In addition, the Company is continuing to evaluate 186RNL in leptomeningeal metastases as part of the ReSPECT-LM Phase 1/2a dose escalation clinical trial and is in late-stage planning for the treatment of pediatric ependymoma and high-grade GBM.
