ACELYRIN, Inc. Announces Additional Phase 2 Data and Phase 3 Program Design for Lonigutamab in Thyroid Eye Disease ACELYRIN, INC. announced additional Phase 2 data and the Phase 3 program design for lonigutamab in Thyroid Eye Disease (TED). Additional Phase 2 data: In the newly announced data from the ongoing Phase 2 trial in TED, lonigutamab demonstrated: Clinically meaningful and competitive improvements across all manifestations of TED, including proptosis, Clinical Activity Score (CAS) and diplopia, as well as the Graves Ophthalmopathy-Quality of Life (GO-QoL) tool: Significant proptosis response rate shown with a 50 mg loading and 25 mg weekly (QW) subcutaneous dose of lonigutamab; Efficacy achieved with lower levels of exposure than seen with IV-administered anti-IGF-1R agents. No cases of hearing impairment as measured by audiogram, hyperglycemia or menstrual disorders in TED patients reported to date at any dose level. 100 mg loading dose achieves target therapeutic concentration within days. Phase 3 LONGITUDE Program: The company also announced the design for its Phase 3 LONGITUDE program, which is informed by significant dose ranging evaluation of subcutaneous lonigutamab in TED patients. Initiation of the Phase 3 program is expected this quarter and topline data are expected in the second half of 2026. LONGITUDE-1 and 2 will be conducted across approximately 350 patients in two global double-masked, placebo-controlled trials to evaluate the safety and efficacy of a subcutaneously delivered 100 mg loading dose of lonigutamab followed by 50 mg every two weeks. Patients will be randomized 2:1 to either lonigutamab or placebo arms during the first 24 weeks, and the primary endpoint in both trials will be proptosis response rate at 24 weeks. All patients will receive lonigutamab after 24 weeks through to 52 weeks of treatment, which is designed to potentially enable longer-term treatment. Both LONGITUDE-1 and LONGITUDE-2 will evaluate “active” TED patients and “chronic” TED patients, with LONGITUDE-1 enrolling a minimum of 81 active patients. The primary endpoint for LONGITUDE-1 will be proptosis response rate at 24 weeks for active patients, with a secondary endpoint of proptosis response rate at 24 weeks for all enrolled patients. LONGITUDE-2 will recruit both active and chronic TED patients and have no minimum number of required active patients. The primary endpoint for LONGITUDE-2 will be proptosis response rate at 24 weeks for all patients. Secondary endpoints for both trials include CAS, diplopia response and GO-QoL at 24 weeks. As previously announced, ACELYRIN held an End of Phase 2 (EOP2) meeting with the United States Food and Drug Administration (FDA) in Third Quarter 2024 and gained alignment on the proposed LONGITUDE-1 and LONGITUDE-2 Phase 3 trial designs.

ACELYRIN, INC. Announces Topline Results From Phase 2b/3 Study of Izokibep for the Treatment of Uveitis ACELYRIN, INC. announced that its Phase 2b/3 trial of izokibep in non-infectious, non-anterior uveitis did not meet the primary endpoint of a statistically significant improvement in time to treatment failure versus placebo as measured by treatment failure rates at 24 weeks. Based on these data, and previously announced guidance regarding other indications, ACELYRIN will not make any additional internal investment in developing izokibep. ACELYRIN will continue to focus on executing its late-stage development program for lonigutamab in thyroid eye disease (TED). About the Phase 2b/3 Uveitis Clinical Trial and Topline Results: The Phase 2b/3 clinical trial (NCT05683496) evaluated izokibep versus placebo in non-infectious, non-anterior uveitis. Patients in the study were randomized 1:1 to receive weekly subcutaneous injections of izokibep 160 mg or placebo. The primary endpoint of the study was improvement in time to treatment failure versus placebo as measured by treatment failure rates at 24 weeks. Key secondary endpoints included measurement of the change in best corrected visual acuity (BCVA), change in visual function as measured by the National Eye Institute’s Visual Function Questionnaire (VFQ25), % change in central retinal thickness (CRT) as measured by Spectral-Domain Optical Coherence Tomography and achievement of Quiescence. In the trial, the treatment failure rate at 24 weeks was 45.0% (p-value: 0.4914) for izokibep and 50.7% for placebo. Statistical significance was not reached for any secondary endpoint and no clinical benefit was observed. Izokibep was well-tolerated in the trial, with a safety profile consistent with previous data and the IL-17A class. ACELYRIN’s revised operating plan in connection with the announcement of the pipeline prioritization and corporate restructuring on August 13, 2024 included the funding of two Phase 3 trials and BLA-enabling activities for lonigutamab, selective pipeline expansion and the completion of the izokibep uveitis trial. Consistent with that plan, there will be no organizational or operational plan changes related to today’s announcement. The Company continues to project that its existing cash resources will provide runway to mid-2027. Duyuru • Nov 14

New minor risk - Shareholder dilution The company's shareholders have been diluted in the past year. Increase in shares outstanding: 2.6% This is considered a minor 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 Risk Revenue is less than US$1m. Minor Risks Currently unprofitable and not forecast to become profitable over next 3 years (US$238m net loss in 3 years). Share price has been volatile over the past 3 months (13% average weekly change). Shareholders have been diluted in the past year (2.6% increase in shares outstanding). Price Target Changed • Aug 14

ACELYRIN, INC. Announces Positive Phase 3 Data for Izokibep in Hidradenitis Suppurativa ACELYRIN, INC announced that the Phase 3 trial of izokibep in Hidradenitis Suppurativa (HS) achieved its primary endpoint of HiSCR75 at 12 weeks, as well as a refocused pipeline strategy that prioritizes lonigutamab in thyroid eye disease (TED) and is projected to extend cash runway. In the global Phase 3 trial in HS, izokibep demonstrated statistically significant responses across multiple e?cacy endpoints at 12 weeks, including 33% of patients receiving izokibep 160mg weekly (QW) achieving HiSCR75, compared to 21% receiving placebo (p-value=0.0294). In higher order endpoints, 25% of patients achieved HiSCR90, compared to 9% on placebo (p-value=0.0009), and 22% of patients achieved HiSCR100, compared to 8% on placebo (p-value=0.001). While the primary endpoint was measured at 12 weeks, ACELYRIN has continued dosing patients in a placebo-controlled manner through week 16. The Company has data from two-thirds of patients at week 16 and the preliminary data demonstrate continued deepening of HiSCR responses over time. No new safety signals for izokibep were observed. The most common adverse events were mild-to-moderate injection site reactions, headache, nasopharyngitis, fatigue and diarrhea. Notably, there were no cases of candida infection, liver toxicity or suicidal ideation/behavior in the izokibep treatment arm. ACELYRIN will complete the on-going PsA and HS trials, but will suspend new investment in these indications. The ongoing Phase 2b/3 trial of izokibep in uveitis will continue through its primary endpoint, with top line data expected in the fourth quarter of 2024. ACELYRIN has completed the Phase 1 proof-of-concept portion of the ongoing lonigutamab trial and the dose-ranging Phase 2 portion in TED patients is continuing. This Phase 2 trial is testing different doses and dose regimens with a goal of establishing a minimum effective dose and enabling selection of the optimal dose and dose regimen for the Phase 3 program. Dose administration every three or four weeks is now being tested. With this dose ranging experience in hand, ACELYRIN plans to forgo the originally planned Phase 2b/3 trial design and move directly into a Phase 3 program, potentially with concurrent trials, which is anticipated to be initiated in the first quarter of 2025. The Company will hold an EOP2 meeting with the FDA later this year and thereafter host an investor presentation to provide additional Phase 2 data and details for the planned Phase 3 program.

New minor risk - Insider selling There has been significant insider selling in the company's shares over the past 3 months. Total value of shares sold: US$199k This is considered a minor risk. There are several reasons why an insider may be selling, including to cover a tax obligation or pay for some other expense. However, we generally consider it a negative if insiders have been selling, especially if they do so below the current price. It implies that they considered a lower price to be reasonable. This is a weak signal, but if there is a pattern of unexplained selling, it can be a sign the insider believes the company's stock is overpriced.

Kessler Topaz Meltzer & Check, LLP Announces Securities Class Action Lawsuit Filed Against Acelyrin, Inc The law firm of Kessler Topaz Meltzer & Check, LLP informed investors that a securities class action lawsuit has been against Acelyrin, Inc. ("Acelyrin"). The action charges Acelyrin with violations of the federal securities laws, including omissions and fraudulent misrepresentations relating to the company's business, operations, and prospects. As a result of Acelyrin's materially misleading statements and omissions to the public, Acelyrin's investors have suffered significant losses. On or around May 5, 2023, Acelyrin conducted its IPO, selling 30 million shares of common stock priced at $18.00 per share. Then, on September 11, 2023, after the markets closed, Acelyrin announced disappointing top-line results from Part B of the Phase 2b/3 trial evaluating "izokibep," the company's lead drug candidate, as it failed to show statistically significant reduction in abscesses and inflammatory nodules in patients as compared to placebo. Following this news, Acelyrin's stock price fell $17.19 per share, or 61.61%, over the following two trading sessions, to close at $10.71 per share on September 13, 2023. After the Class Period and, most recently, after the markets closed on November 27, 2023, the company revealed that the Contract Research Organization which was hired by Acelyrin to run the izokibep trials had incorrectly programmed the testing protocol, resulting in a sequencing error that went further unidentified through the providers' testing processes.

Acelyrin, Inc. Provides Update on Izokibep Clinical Development Program ACELYRIN, INC. provided an update on its izokibep clinical development program, including its ongoing global Phase 2b/3 trial for izokibep in psoriatic arthritis (PsA trial). Background: In September 2023, ACELYRIN disclosed top-line results from Part B of its Phase 2b/3 trial evaluating izokibep for the treatment of moderate-to-severe Hidradenitis Suppurativa (“HS trial”). Given certain confounding factors observed in the trial, including responder discontinuations without adverse events and a marked increase in placebo rates arising in the latter half of the study, the Company implemented quality control measures above and beyond standard protocol for the ongoing open-label extension of the HS trial, the ongoing Phase 3 trial in HS, and the ongoing PsA trial. These trials are being conducted by the same Contract Research Organization (CRO). The CRO does not conduct any trials on behalf of ACELYRIN beyond the izokibep clinical program. PsA Trial: The ongoing PsA trial is designed with four arms: 160mg dosed every week (QW), 160mg dosed every other week (Q2W), 80mg dosed every four weeks (Q4W) and placebo. ACELYRIN’s team recently identified clinical trial execution errors involving its CRO and one of the vendors engaged by the CRO. ACELYRIN has confirmed that the protocol, which outlined dosing sequence, was correct. However, ACELYRIN’s protocol was programmed incorrectly by the vendor, resulting in a sequencing error that went further unidentified through the providers’ testing processes. As a result, some patients in the 160mg Q2W and 80mg Q4W arms received placebo and active treatment in random order rather than in an alternating pattern as intended. Importantly, there is no risk to patient safety resulting from the sequencing errors and no patient received more active treatment than was already included in the protocol for the most frequent 160mg QW dosing arm. The programming error has been addressed and the dosing sequence has been corrected. Work is ongoing to determine the implications of the sequencing errors in the 160mg Q2W and 80mg Q4W arms. Based on ACELYRIN’s review to date and the fact that the placebo and 160mg QW arms were designed for consistent weekly dosing, the Company has no reason to believe the 160mg QW and placebo arms are impacted. Next Steps: ACELYRIN’s wide-ranging review of the ongoing izokibep trials, including operational execution by the CRO, is continuing. ACELYRIN will contract with a third-party to conduct an independent audit of the trials being conducted by the CRO for ACELYRIN, including the HS trial and the PsA trial. ACELYRIN will not use this CRO for any new trials that it conducts. Based on the outcome of its ongoing evaluation and the planned audit, the Company will determine the best path forward for the development of izokibep on behalf of patients. This will include a determination of whether to transition its ongoing trials to a new CRO or complete the trials with the current CRO. Pending completion of the evaluation from the third-party auditor, ACELYRIN plans to report top-line data from its PsA trial in the first quarter of 2024. The Company previously presented differentiated 16- and 46-week data up to 80mg every other week from a Phase 2 trial of izokibep in PsA that was not conducted by the CRO. These results demonstrated dose-ordered responses as early as one month into treatment and increasing over time. Long-term efficacy results from the same trial presented recently at the American College of Rheumatology annual meeting showed that with longer duration of treatment, patients experienced durable and deepening resolution of disease across clinical manifestations of PsA, leading to further improvements in quality of life as measured by the Psoriatic Arthritis Impact of Disease questionnaire. Modeling from the Phase 2 PsA data predicted the potential for increased efficacy with higher doses over the 80mg Q2W. The ongoing PsA trial includes higher doses designed to evaluate the potential to further maximize responses for patients. Duyuru • Nov 18
