Barinthus Bio Completes Enrollment for Phase 2b HBV003 Clinical Trial in Chronic Hepatitis B and Phase 1 PCA001 Clinical Trial in Prostate Cancer Barinthus Biotherapeutics plc announced the completion of enrollment for two clinical trials: HBV003, a Phase 2b clinical trial of VTP-300 in adults with chronic hepatitis B (CHB); and PCA001, a Phase 1 clinical trial of VTP-850 in men with rising prostate-specific antigen (PSA) after definitive local therapy for prostate cancer (i.e., biochemical recurrence). The Phase 2b HBV003 trial (NCT05343481) has enrolled 121 participants and is designed to obtain critical dosing information for a potential functional cure regimen for CHB, with participants receiving VTP-300 and low-dose (LD) nivolumab. This trial design builds on positive monotherapy results from the clinical study HBV002, which included an evaluation of VTP-300 given alone and in combination with LD nivolumab. Earlier this year, interim data from the HBV003 trial was presented at the European Association for the Study of the Liver (EASL) Congress and demonstrated that treatment with VTP-300 and LD nivolumab is generally well-tolerated and led to a sustained decline in Hepatitis B surface antigen (HBsAg) levels. Participants reaching Day 169 were assessed for NUC therapy discontinuation eligibility in line with the study criteria, with 76% of participants meeting the criteria (n=16/21). 19% of the eligible participants (n=4/21) reached undetectable levels of HBsAg, with 2 of these patients maintaining undetectable levels for over 16 weeks. The PCA001 Phase 1 trial (NCT05617040) has enrolled 22 participants and is designed to determine the recommended Phase 2 dosing regimen of VTP-850 as well as evaluate safety and efficacy, as measured by PSA and T cell response. VTP-850 is a next-generation prostate cancer immunotherapeutic candidate which utilizes Barinthus Bio’s ChAdOx/MVA platform of two proprietary nonreplicating viral vectors in a sequential dosing approach.

Barthus Biotherapeutics plc Announces Updated Data from Two Clinical Trials in People with Chronic Hepat B Barinthus Biotherapeutics plc announced the presentation of updated data from two clinical trials in people with chronic hepatitis B (CHB) at the European Association for the Study of the Liver (EASL) Congress 2024. The presentations include updated interim data from the Phase 2b clinical trial (HBV003), as well as new interim EOT data from the Phase 2a clinical trial (IM-PROVE II, AB-729-202) in partnership with Arbutus Biopharma, both in people with CHB receiving ongoing SoC NUC therapy. Interim data from the HBV003 trial indicate that treatment with VTP-300 and low-dose nivolumab is generally well-tolerated and sustained HBsAg declines were observed across all groups, with some participants reaching undetectable levels of HBsAg. As of the data cutoff on April 15, 2024, 91 out of a planned 120 virally suppressed patients with CHB on stable NUC therapy were enrolled in the trial, 40 of whom had screening HBsAg =200 IU/mL as per the study protocol amendment in 2023 and 21 of whom had been assessed for NUC discontinuation. Participants reaching Day 169 were assessed to confirm if they were eligible to discontinue NUC therapy in line with the study criteria. Data presented focuses on participants with baseline HBsAg =200 IU/mL: 76% of assessed participants (n=16/21) were eligible for NUC discontinuation at EOT, 7 of these discontinued. 71% (n=5/7) remained off NUC therapy, up to 44 weeks post-discontinuation in one case. 19% of participants (n=4/21) across the groups assessed for NUC discontinuation, had undetectable HBsAg at any time. This has been maintained for =16 weeks in 2 cases. 67% of participants (n=14/21) across all groups assessed for NUC discontinuation had HBsAg <10 IU/mL at Week 24 or later. Robust T cell responses as measured by IFN? ELISpot were observed to all encoded antigens. There were no Serious Adverse Events (SAEs), Grade 3 or 4 Adverse Events (AEs) related to treatment. There was one treatment discontinuation due to an AE. The most common treatment-related AE was thyroid dysfunction, reported in 9% of participants (n=8/91) with normal Thyroid Function Tests reported in 7 of 8 (88%) at last recorded visit. Transient alanine transaminase (ALT) elevations occurred in 14 participants through to Day 85. Data from IM-PROVE II as of the data cutoff on April 12, 2024, indicate that treatment with imdusiran, Arbutus’ RNAi therapeutic candidate, followed by Barinthus Bio's T-cell stimulating immunotherapeutic candidate, VTP-300, was generally well-tolerated and observed to maintain low HBsAg levels during the post-treatment follow-up period. The data were presented today by Dr. Kosh Agarwal, MD, Consultant Hepatologist and Transplant Physician at the Institute of Liver Studies at King’s College Hospital, London, during a session focused on new treatments for viral hepatitis B at the EASL Congress. Dr. Agarwal presented the following data from 38 of 40 participants that were on stable NUC therapy throughout the treatment period. They received imdusiran (60mg every 8 weeks) for 24 weeks and were then randomized to receive either VTP-300 or placebo at Weeks 26 and 30: Robust reductions of HBsAg were observed during the imdusiran lead-in period with 95% of patients achieving HBsAg <100 IU/mL before undergoing dosing in the VTP-300 treatment or placebo groups. At 24-weeks post-EOT, there was a significant difference (p<0.05) in HBsAg levels between the VTP-300 treatment group (n=5) and placebo (n=6). 94% of participants (n=18/19) in the VTP-300 treatment group achieved HBsAg levels of <100 IU/mL and 36% had <10 IU/mL (n=7/19) at EOT (Week 48) compared to the placebo group, 84% (n=16/19) and 21% (n=4/19), respectively. ?Similarly, at 24-weeks post-EOT (Week 72), the VTP-300 treatment group had lower HBsAg levels with 80% of participants at <100 IU/mL (n= 4/5) and 60% at <10 IU/mL (n=3/5) than the placebo group, 16% (n=1/6) and 0% (n=0/6), respectively. 84% of participants (n=16/19) in the VTP-300 treatment group met criteria at EOT (Week 48) to discontinue NUC therapy vs 52% in the placebo group (n=10/19). In the VTP-300 treatment group, 20% of participants (n=1/5) achieved undetectable HBsAg at 24-weeks post-EOT and a further 20% of participants (n=1/5) had a >1.5log10 decline between the last two visits during the NUC therapy discontinuation follow-up period. Treatment with imdusiran and VTP-300 was generally well-tolerated. There were no reported SAEs, Grade 3 or 4 AEs or discontinuations due to treatment. The most common treatment-related AEs in two or more patients were injection site-related (both imdusiran and VTP-300) and transient ALT increases (imdusiran). Reported Earnings • May 14

BarinthuBarinthus Biotherapeutics plc Announces Topline Data from Phase 1b/2 APOLLO Trial of VTP-200 in Persistent High-Risk Human Papillomavirus (HPV) Infections Barinthus Biotherapeutics plc announced topline final data from the APOLLO trial (also known as HPV001), a completed randomized, placebo-controlled Phase 1b/2 dose-ranging trial of VTP-200 in women with low-grade cervical lesions associated with persistent hrHPV infection. APOLLO (NCT04607850) was a randomized, placebo-controlled Phase 1b/2 multi-center trial of 108 participants across the UK and EU evaluating the safety, tolerability and immunogenicity of VTP-200 in women aged 25-55 with persistent hrHPV infection and low-grade cervical lesions. The primary objective was to evaluate the safety and tolerability of VTP-200. The trial was also designed to assess the effect of VTP-200 on clearance of hrHPV infection and cervical lesion(s), as well as select appropriate doses for further development. The APOLLO study met its primary safety endpoint, demonstrating that VTP-200 was generally well-tolerated and was administered with no treatment-related grade 3 or higher unsolicited AEs and no treatment-related SAEs. The hrHPV clearance rate of 60% at Month 12 was observed in group 2, which included the dose of ChAdOx, compared to a 33% clearance rate in the placebo group. Groups 1, 3, 4 and 5 showed 12%, 11%, 33% and 36% hrHPV clearance rates, respectively. The study also evaluated cervical lesion clearance rates in participants with both reported lesions at screening and visualization of the cervical transformation zone at 12 months (n=57). The cervical lesion clearance rate of 67% was observed in group 2 and group 5, both received the dose of ChAdOx, compared to 39% in the placebo group. Groups 1, 3 and 4 showed 40%, 20% and 33% cervical lesion clearance rates, respectively. Pooled data from the five active dose groups showed no significant improvement in hrHPV clearance or cervical lesion clearance rates in comparison to the placebo group. Future development options for the VTP-200 program are currently being evaluated with further analyses ongoing. New Risk • Apr 05
New minor risk - Share price stability The company's share price has been volatile over the past 3 months. It is more volatile than 75% of American stocks, typically moving 12% a week. This is considered a minor risk. Share price volatility indicates 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. It also 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. Currently, the following risks have been identified for the company: Major Risks Earnings are forecast to decline by an average of 13% per year for the foreseeable future. Revenue is less than US$1m (US$802k revenue). Minor Risks Currently unprofitable and not forecast to become profitable over next 3 years (US$126m net loss in 3 years).

Arbutus Biopharma Corporation and Barinthus Biotherapeutics plc Present Preliminary Data from Phase 2A Clinical Trial Combining Imdusiran with VTP-300 at AASLD Arbutus Biopharma Corporation and Barinthus Biotherapeutics plc announced preliminary data from the Phase 2a clinical trial (AB-729-202) combining Arbutus' RNAi therapeutic, imdusiran (AB-729), with Barinthus Bio's T-cell stimulating immunotherapeutic, VTP-300, and standard-of-care nucleos(t)ide analogue (NA) therapy. Clinical trial AB-729-202 enrolled 40 non-cirrhotic, virally suppressed cHBV patients that were on stable NA therapy. The patients initially received imdusiran (60mg every 8 weeks) for 24 weeks and were then randomized to receive either VTP-300 or placebo at week 26 and 30 (and conditionally at week 38 if they experienced a >0.5 log10 decline in HBsAg between weeks 26 and 34), in addition to ongoing NA therapy. The preliminary data include a subset of patients that received the two dose VTP- 300 regimen (28/40 patients) and available follow-up data to week 48 (12/40 patients) and showed the following: · Robust reductions of HBsAg were seen during the imdusiran treatment period (-1.86 log10 mean reduction from baseline after 24 weeks of treatment). This decline in HBsAg is comparable to the declines seen with imdusiran in other clinical trials conducted to date. · 97% of the imdusiran treated patients (33/34) had HBsAg <100 IU/mL at the time of the first VTP-300/placebo dose. VTP-300 treatment appears to contribute to the maintenance of low HBsAg levels in the early post-treatment period, as the mean HBsAg levels in the placebo group begin to increase starting ~12 weeks after the last dose of imdusiran. All VTP-300 treated patients have maintained HBsAg <100 IU/mL through week 48, 60% have maintained HBsAg <10 IU/mL, and all have qualified to stop NA therapy. Preliminary immunology data suggests HBV-specific T cell IFN- production is enhanced in patients receiving imdusiran plus VTP-300 compared to placebo. The preliminary safety data from this trial demonstrate that imdusiran and VTP-300 were both safe and well-tolerated. There were no serious adverse events, Grade 3 or 4 adverse events or treatment discontinuations. Reported Earnings • Nov 11

Vaccitech plc Announces Positive Final Data EASL Congress for Phase 1B/2 HBV002 Study in Adults with Chronic Hepatitis B Vaccitech plc announced present positive final data from the HBV002 clinical trial at the European Association for the Study of the Liver (EASL) Congress 2023 – The International Liver CongressTM taking place June 21-24 in Vienna, Austria. HBV002 (NCT04778904) is a Phase 1b/2a clinical trial of VTP-300 in adults with chronic Hepatitis B (CHB). The data will be presented as a poster at EASL on, June 24 (Poster ID: SAT-198), by Eleanor Barnes, Professor of Hepatology and Experimental Medicine at Oxford University. Meaningful, durable reductions of Hepatitis B Surface Antigen (HBsAg) were seen in all participants with a >0.5 log10 reduction in HBsAg who received VTP-300 alone (Group 2) or in combination with a single administration of low-dose PD-1 inhibitor, nivolumab (Group 3). Two of five patients with baseline HBsAg below 100 IU/mL in Group 3, developed a non-detectable HBsAg level, which continued eight months after last dose. Reductions in HBsAg were most prominent in those with lower baseline HBsAg. Importantly, all participants who received VTP-300 and experienced a >0.5 log10 reduction in HBsAg had durable responses with reductions in HBsAg persisting through to the last measurement eight months post-final dose. VTP-300, encoding Hepatitis B virus (HBV) genotype C antigens, led to a decline in HBsAg in the majority of people infected with genotypes B and C viruses. In addition, VTP-300-induced T cells showed cross-reactivity to the core antigen from genotypes A to E in ELISpot assays using PBMC from VTP-300-treated healthy subjects and genotype-specific peptides A-E. A robust T cell response was generated against all VTP-300 antigens and was highest in the VTP-300 alone group. In that group, there was a relation between ELISpot responses and HBsAg decline.

Vaccitech plc Doses First Patient in Pca001, A Prostate Cancer Phase 1/2 Clinical Trial of Vtp-850 Vaccitech plc announced the dosing of the first patient in the PCA001 clinical trial (NCT05617040). PCA001 is a multi-centre, Phase 1/2 clinical trial designed to determine the recommended Phase 2 regimen and evaluate the safety, efficacy, as measured by prostate-specific antigen (PSA) response, and T cell response of VTP-850 monotherapy in men with rising PSA after definitive local therapy for their disease (i.e., biochemical recurrence). VTP-850 is a next-generation prostate cancer immunotherapeutic candidate which utilizes Vaccitech's sequential dosing approach of two proprietary nonreplicating viral vectors, ChAdOx and MVA. PCA001 builds on the previous promising data from the University of Oxford VANCE01 (NCT02390063) and ADVANCE (NCT03815942) trials, Phase 1 and Phase 1/2 clinical trials respectively, of VTP-800, the first-generation product candidate which encoded 5T4, an antigen expressed by most prostate cancers.1,2 VTP-850 is a multi-antigen immunotherapeutic candidate containing four prostate-associated antigens: PSA, PAP, STEAP1 and 5T4. The first phase of the trial is enrolling participants in the US, with plans to open further sites in Italy and Spain. Major Estimate Revision • May 19
