SAN DIEGO, CA, USA I May 05, 2025 I Janux Therapeutics, Inc. (Nasdaq: JANX) (Janux), a clinical-stage biopharmaceutical company developing a broad pipeline of novel immunotherapies by applying its proprietary technology to its Tumor Activated T Cell Engager (TRACTr) and Tumor Activated Immunomodulator (TRACIr) platforms, today announced the initiation of Phase 1b expansion studies in the ongoing ENGAGER-PSMA-01 trial. ENGAGER-PSMA-01 is a first-in-human, open-label, multicenter Phase 1 clinical trial designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy of JANX007 administered as monotherapy or in combination in adult patients with advanced metastatic castration-resistant prostate cancer (mCRPC). In December 2024, Janux reported positive interim clinical data from the Phase 1a dose escalation portion of the trial in 16 mCRPC patients with a median of four prior lines of therapy. At that time, the median radiographic progression-free survival (rPFS) reported was 7.4 months for all 16 patients.* As of April 21, 2025, updated results** have been achieved in the same 16 patients supporting the initiation of the Phase 1b expansion studies: *8/16 patients were noted as in-progress in the December 2024 reported results. **rPFS results based upon Kaplan-Meier estimate. In addition, Janux has selected a CRS-mitigation strategy to support the initiation of the Phase 1b expansion studies that is designed to maintain the CRS profile reported in December. The first Phase 1b expansion study will enroll taxane-naïve mCRPC patients and is designed to generate additional safety and efficacy data in this first and second line (1L/2L) patient population. This study will assess JANX007 monotherapy at two dose regimens (0.3/2/6mg and 0.3/2/9mg) with dosing administered once weekly or once every two weeks in mCRPC patients who have progressed on or after novel hormonal therapy (NHT). “Initiation of the taxane-naïve study marks an important step as we begin to evaluate JANX007 in earlier-line mCRPC patient populations,” said Zachariah McIver, D.O., Ph.D., Chief Medical Officer of Janux. “While therapeutic options for mCRPC have expanded, there remains a significant need for novel, non-chemotherapeutic approaches.” Janux plans to initiate three additional Phase 1b expansion studies, evaluating: “Improved efficacy and durability of responses has been observed by other prostate cancer drugs and TCEs when moving into earlier lines of therapy. There are also indications that safety with TCEs improve in earlier lines of therapy where disease burden is lower. We believe that these observations, coupled with the data seen in our Phase 1a dose escalation in later line patients, strongly support our decision to develop JANX007 in earlier lines of therapy,” said David Campbell, Ph.D., President and CEO of Janux. Additional data from JANX007 and JANX008 will be presented at future Janux events in the second half of 2025. Separately, Janux will host an R&D Day in mid-2025 highlighting product candidates identified from its preclinical pipeline to move into clinical trials. Janux’s TRACTr and TRACIr Pipeline Janux’s first clinical candidate, JANX007, is a TRACTr that targets prostate-specific membrane antigen (PSMA) and is being investigated in a Phase 1 clinical trial in adult patients with metastatic castration-resistant prostate cancer. Janux’s second clinical candidate, JANX008, is a TRACTr that targets epidermal growth factor receptor (EGFR) and is being studied in a Phase 1 clinical trial for the treatment of multiple solid cancers including colorectal carcinoma, squamous cell carcinoma of the head and neck, non-small cell lung cancer, renal cell carcinoma, small cell lung cancer, pancreatic ductal adenocarcinoma and triple-negative breast cancer. We are also generating a number of additional TRACTr and TRACIr programs for potential future development, some of which are at development candidate stage or later. We are currently assessing priorities in our preclinical pipeline. About Janux Therapeutics Janux is a clinical-stage biopharmaceutical company developing tumor-activated immunotherapies for cancer. Janux’s proprietary technology enabled the development of two distinct bispecific platforms: TRACTr and TRACIr.

Continued oncology pipeline advancement with a strategic focus on two priority pan-tumor programs: next-generation immunomodulator BNT327, a bispecific antibody targeting PD-L1 and VEGF-A1, and mRNA cancer immunotherapies Presented multiple clinical updates across oncology pipeline underlining BioNTech’s combination strategy in oncology with first data presented for the novel combination of BNT327 plus antibody-drug conjugates (“ADCs”) Development and commercial preparation for a 2025/2026 season variant-adapted COVID-19 vaccine First quarter 2025 revenues of €0.2 billion2, net loss of €0.4 billion and basic and diluted loss per share of €1.73 ($1.823) Maintained strong financial position with €15.9 billion in cash, cash equivalents and security investments as of March 31, 20254 Full year 2025 financial guidance confirmed Conference call and webcast scheduled for May 5, 2025, at 8:00 a.m. EDT (2:00 p.m. CEST) MAINZ, Germany, May 5, 2025 (GLOBE NEWSWIRE) -- BioNTech SE (Nasdaq: BNTX, “BioNTech” or “the Company”) today reported financial results for the three months ended March 31, 2025 and provided an update on its corporate progress. “In the first quarter of 2025, we demonstrated continued execution against our strategic focus areas, highlighted by data updates for our PD-L1xVEGF-A bispecific antibody candidate BNT327 and the progress in clinical evaluation of our focus programs and combination treatment approaches,” said Prof. Ugur Sahin, M.D., CEO and Co-Founder of BioNTech. “We will continue to focus on our key strategic programs as we remain steadfast in our vision to translate our science into survival for patients in need.” Financial Review for First Quarter 2025 Revenues reported were €182.8 million for the three months ended March 31, 2025, compared to €187.6 million for the comparative prior year period. Revenues during the first quarter of 2025 were mainly driven by revenues derived from BioNTech’s COVID-19 vaccine collaboration. Cost of sales were €83.8 million for the three months ended March 31, 2025, compared to €59.1 million for the comparative prior year period. The change was mainly due to a positive impact of an inventory revaluation in the first quarter of 2024. Research and development (“R&D”) expenses were €525.6 million for the three months ended March 31, 2025, compared to €507.5 million for the comparative prior year period. The increase was mainly driven by progressing late-stage clinical studies for candidates in BioNTech’s ADC and antibody portfolio. Sales, general and administrative (“SG&A”) expenses5, in total, amounted to €120.6 million for the three months ended March 31, 2025, compared to €132.6 million for the comparative prior year period. The decrease was primarily driven by a reduction in external services. Income taxes were realized with an amount of €29.6 million in tax income for the three months ended March 31, 2025, compared to €16.7 million in realized tax income for the comparative prior year period. Net loss was €415.8 million for the three months ended March 31, 2025, compared to a net loss of €315.1 million for the comparative prior year period. Cash and cash equivalents plus security investments as of March 31, 2025, reached €15,854.4 million, comprising €10,184.9 million in cash and cash equivalents, €3,542.0 million in current security investments and €2,127.5 million in non-current security investments. Basic and diluted loss per share was €1.73 for the three months ended March 31, 2025, compared to a basic and diluted loss per share of €1.31 for the comparative prior year period. Shares outstanding as of March 31, 2025, were 240,392,622, excluding 8,159,578 shares held in treasury. “Our revenues for the first quarter reflect the seasonal demand for COVID-19 vaccines and are in line with our expectations,” said Jens Holstein, CFO of BioNTech. “BioNTech’s robust financial position empowers us to pursue our strategic goal of evolving into a leading biotech company with multiple oncology products by 2030.” 2025 Financial Year Guidance Confirmed6 BioNTech expects its revenues for the full 2025 financial year to be in the range of €1,700 - €2,200 million and revenue phasing similar to 2024, primarily concentrated in the last three to four months, driving the full year revenue figure. The revenue guidance assumes: relatively stable vaccination rates, pricing levels and market share compared to 2024; estimated inventory write-downs and other charges by BioNTech’s collaboration partner Pfizer that negatively influence BioNTech’s revenues; anticipated revenues from a pandemic preparedness contract with the German government; and anticipated revenues from the BioNTech Group service businesses. Potential changes to the law or governmental policy, including tariffs and public health policy, and evolving public sentiment worldwide, could further negatively impact our anticipated revenues and expenses. Planned 2025 Financial Year Expenses and Capex BioNTech expects to continuously focus investments on R&D and scaling the business for late-stage development and commercial readiness in oncology, while remaining cost-disciplined. Strategic capital allocation will continue to be a key driver of the Company’s trajectory. As part of BioNTech’s strategy, the Company may continue to evaluate appropriate corporate development opportunities with the aim of driving sustainable long-term growth and create future value.The full interim unaudited condensed consolidated financial statements can be found in BioNTech’s Report on Form 6-K for the period ended March 31, 2025, filed today with the United States Securities and Exchange Commission (“SEC”) and available at www.sec.gov.

Operational Review for the First Quarter 2025, Key Post Period-End Events and 2025 Outlook Selected Oncology Pipeline Updates Next-Generation Immunomodulators BNT327, formerly also known as PM8002, is a bispecific antibody candidate combining PD-L1 checkpoint inhibition with VEGF-A neutralization. In March 2025, at the European Lung Cancer Congress (“ELCC”), preliminary data from two Phase 2 clinical trials conducted in China in first-line extensive-stage small cell lung cancer (“ES-SCLC”) and second-line small cell lung cancer (“SCLC”) were presented. Preliminary data from the ongoing single-arm, open-label Phase 2 clinical trial (NCT05844150) evaluating BNT327 in combination with chemotherapy as a first-line treatment in patients with ES-SCLC showed anti-tumor activity and an acceptable safety profile with no new safety signals beyond those typically described for chemotherapy agents and anti-PD-(L)1 and anti-VEGF monotherapies. These data were the first presented for BNT327 as a potential first-line treatment in ES-SCLC supporting the ongoing global randomized Phase 3 clinical trial ROSETTA Lung-01 (NCT06712355). Preliminary data from the ongoing Phase 2 clinical trial (NCT05879068) evaluating BNT327 in combination with chemotherapy as a second-line treatment in patients with SCLC showed anti-tumor activity, which was observed regardless of prior immuno-oncology treatment, and an acceptable safety profile. In April 2025, at the American Association for Cancer Research (“AACR”) Annual Meeting 2025, first data were presented for the novel combination of the PD-L1xVEGF-A bispecific antibody candidate BNT327 with various ADC candidates. Interim data from the ongoing Phase 1/2 clinical trial (NCT05438329) evaluating BNT327 with BNT325/DB-1305, a TROP2-targeting ADC candidate being developed in collaboration with Duality Biologics (Suzhou) Co. Ltd. (“DualityBio”), in patients with advanced/metastatic solid tumors showed a manageable safety profile and early signs of anti-tumor activity in a cohort with patients with platinum-resistant ovarian cancer (“PROC”). Across the 13 efficacy evaluable patients with PROC, seven patients achieved partial response and three stable disease. Responses were also observed in patients with non-small cell lung cancer (“NSCLC”) or triple-negative breast cancer (“TNBC”). Preliminary data from the ongoing single-arm, open-label Phase 2 clinical trial (NCT05844150) evaluating BNT327 in combination with chemotherapy as a first-line treatment in patients with ES-SCLC showed anti-tumor activity and an acceptable safety profile with no new safety signals beyond those typically described for chemotherapy agents and anti-PD-(L)1 and anti-VEGF monotherapies.

Phase 1b expansion study initiated in taxane-naïve mCRPC patients Updated data from Phase 1a dose escalation support initiation of Phase 1b dose expansion Updates on JANX007 and JANX008 expected in the second half of 2025 Janux to host R&D Day in mid-2025 highlighting preclinical pipeline progression to the clinic SAN DIEGO--(BUSINESS WIRE)-- Janux Therapeutics, Inc. (Nasdaq: JANX) (Janux), a clinical-stage biopharmaceutical company developing a broad pipeline of novel immunotherapies by applying its proprietary technology to its Tumor Activated T Cell Engager (TRACTr) and Tumor Activated Immunomodulator (TRACIr) platforms, today announced the initiation of Phase 1b expansion studies in the ongoing ENGAGER-PSMA-01 trial. ENGAGER-PSMA-01 is a first-in-human, open-label, multicenter Phase 1 clinical trial designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy of JANX007 administered as monotherapy or in combination in adult patients with advanced metastatic castration-resistant prostate cancer (mCRPC). In December 2024, Janux reported positive interim clinical data from the Phase 1a dose escalation portion of the trial in 16 mCRPC patients with a median of four prior lines of therapy. At that time, the median radiographic progression-free survival (rPFS) reported was 7.4 months for all 16 patients.* As of April 21, 2025, updated results** have been achieved in the same 16 patients supporting the initiation of the Phase 1b expansion studies: Median rPFS of 7.5 months (n=16) Median rPFS of 7.9 months for patients treated at 6mg and 9mg target doses (n=9) 6-month rPFS of 65% (n=16) 6-month rPFS of 78% for patients treated at 6mg and 9mg target doses (n=9) Safety data remained consistent with the December 2024 data disclosure (n=16) *8/16 patients were noted as in-progress in the December 2024 reported results. **rPFS results based upon Kaplan-Meier estimate. In addition, Janux has selected a CRS-mitigation strategy to support the initiation of the Phase 1b expansion studies that is designed to maintain the CRS profile reported in December. The first Phase 1b expansion study will enroll taxane-naïve mCRPC patients and is designed to generate additional safety and efficacy data in this first and second line (1L/2L) patient population. This study will assess JANX007 monotherapy at two dose regimens (0.3/2/6mg and 0.3/2/9mg) with dosing administered once weekly or once every two weeks in mCRPC patients who have progressed on or after novel hormonal therapy (NHT). “Initiation of the taxane-naïve study marks an important step as we begin to evaluate JANX007 in earlier-line mCRPC patient populations,” said Zachariah McIver, D.O., Ph.D., Chief Medical Officer of Janux. “While therapeutic options for mCRPC have expanded, there remains a significant need for novel, non-chemotherapeutic approaches.” Janux plans to initiate three additional Phase 1b expansion studies, evaluating: JANX007 in combination with an androgen receptor inhibitor in taxane-experienced mCRPC patients JANX007 monotherapy in PARP inhibitor-resistant mCRPC patients JANX007 monotherapy in NHT- and taxane-experienced mCRPC patients designed to support OPTIMUS dose selection for registrational studies “Improved efficacy and durability of responses has been observed by other prostate cancer drugs and TCEs when moving into earlier lines of therapy. There are also indications that safety with TCEs improve in earlier lines of therapy where disease burden is lower. We believe that these observations, coupled with the data seen in our Phase 1a dose escalation in later line patients, strongly support our decision to develop JANX007 in earlier lines of therapy,” said David Campbell, Ph.D., President and CEO of Janux. Additional data from JANX007 and JANX008 will be presented at future Janux events in the second half of 2025. Separately, Janux will host an R&D Day in mid-2025 highlighting product candidates identified from its preclinical pipeline to move into clinical trials. Janux’s TRACTr and TRACIr Pipeline Janux’s first clinical candidate, JANX007, is a TRACTr that targets prostate-specific membrane antigen (PSMA) and is being investigated in a Phase 1 clinical trial in adult patients with metastatic castration-resistant prostate cancer. Janux’s second clinical candidate, JANX008, is a TRACTr that targets epidermal growth factor receptor (EGFR) and is being studied in a Phase 1 clinical trial for the treatment of multiple solid cancers including colorectal carcinoma, squamous cell carcinoma of the head and neck, non-small cell lung cancer, renal cell carcinoma, small cell lung cancer, pancreatic ductal adenocarcinoma and triple-negative breast cancer. We are also generating a number of additional TRACTr and TRACIr programs for potential future development, some of which are at development candidate stage or later. We are currently assessing priorities in our preclinical pipeline. About Janux Therapeutics Janux is a clinical-stage biopharmaceutical company developing tumor-activated immunotherapies for cancer. Janux’s proprietary technology enabled the development of two distinct bispecific platforms: TRACTr and TRACIr. The goal of both platforms is to provide cancer patients with safe and effective therapeutics that direct and guide their immune system to eradicate tumors while minimizing safety concerns. Janux is currently developing a broad pipeline of TRACTr and TRACIr therapeutics directed at several targets to treat solid tumors. Janux has two TRACTr therapeutic candidates in clinical trials, the first targeting PSMA is in development for prostate cancer, and the second targeting EGFR is being developed for colorectal carcinoma, squamous cell carcinoma of the head and neck, non-small cell lung cancer, renal cell carcinoma, small cell lung cancer, pancreatic ductal adenocarcinoma and triple-negative breast cancer.
