    – Experienced leader in immuno-oncology drug development Robert Ilaria, Jr. to head eganelisib clinical development –

    – Brian Schwartz, M.D., transitioning from Consulting Chief Physician to Infinity's Board of Directors –

    Infinity Pharmaceuticals, Inc. (NASDAQ:INFI) a clinical-stage biotechnology company developing eganelisib, a potentially first-in-class, oral, immuno-oncology macrophage reprogramming therapeutic which is designed to address a fundamental biologic mechanism of immune suppression in cancer, today announced the appointment of Robert Ilaria, Jr., M.D. as Chief Medical Officer. In addition, Brian Schwartz, M.D., will be transitioning from his role as Consulting Chief Physician to the Infinity Board of Directors.

    "Robert's deep expertise in oncology drug development, with a focus in immuno-oncology – most recently leading the Celgene/BeiGene PD-1 inhibitor collaboration and Bristol Myers Squibb's CTLA-4 program, will be a tremendous asset to Infinity at this exciting point in the trajectory of eganelisib's development," said Adelene Perkins, Chief Executive Officer and Chair, Infinity Pharmaceuticals. "Robert's extensive experience in drug development will be critically important as we build upon the compelling eganelisib data presented over the last year and initiate future studies to maximize eganelisib's considerable potential."

    Dr. Ilaria said, "I'm thrilled to join Infinity at this important time in the development of eganelisib given the strength of the data generated to date across multiple indications and treatment settings which provide strong evidence that eganelisib has the potential to be a transformative therapy in immuno-oncology. These eganelisib data underscore the importance of reprogramming macrophages in the tumor microenvironment to improve outcomes for patients with some of the greatest unmet needs in solid tumors. I look forward to working to advance eganelisib in registration enabling studies to leverage the benefit shown for patients with urothelial cancer and triple negative breast cancer, including in patients who are PD-L1 negative for whom treatment options are limited."

    Dr. Schwartz said, "During my time leading eganelisib's development, I have been extremely encouraged by the data generated from MARIO-275, MARIO-3 and MARIO-1, which demonstrate notable improvements in overall survival and progression free survival in bladder cancer and initial evidence of durable clinical activity in triple negative breast cancer. These data, along with the demonstrated ability to overcome resistance to checkpoint inhibition in patients with melanoma and squamous cell cancer of the head and neck cancer, show consistent patient benefit and on-mechanism immune modulation with eganelisib across some of the most challenging patient populations and clinical settings. I'm thrilled to continue contributing to the development of eganelisib in the capacity of a board member and look forward to working with Robert to ensure a seamless transition as he takes the helm of clinical development at Infinity."

    Ms. Perkins added, "We are tremendously grateful for Brian's impactful contributions across our clinical programs through key data readouts that pave the way for future development and are delighted he will be joining the Infinity Board of Directors to provide continued strategic insight as we plan for a registration study in bladder cancer and determine the best path forward in triple negative breast cancer based on maturing data to be presented by year end."

    Dr. Ilaria joins Infinity from Bristol Myers Squibb where he was most recently the CTLA-4 Development Program Leader. He was previously Executive Medical Director, Global Clinical Research and Development at Celgene and Program Lead Physician for the PD-1 inhibitor tislelizumab partnership with BeiGene. Dr. Ilaria progressed through increasingly senior leadership roles in the global clinical development of over 20 drug candidates during 12 years at Eli Lilly and Company, resulting in Fast Track and Breakthrough Designations and accelerated approvals, and provided medical support for global regulatory submissions as well as launch and post-launch activities. Dr. Ilaria received his MD at University of Texas Southwestern Medical School, Dallas, Texas followed by internship/residency in internal medicine at Brigham and Women's Hospital, a research post-doctoral fellowship at Harvard Medical School and a hematology and medical oncology fellowship at Brigham and Women's Hospital and the Dana Farber Cancer Institute.

    Dr. Schwartz has over 25 years of experience as a drug development expert in pharmaceutical and biotechnology industries and has served as Infinity's consulting Chief Physician since early 2020. He was previously at ArQule for 10 years where he served as CMO prior to the acquisition by Merck & Co. of ArQule in late 2019. In senior leadership roles at ArQule, Ziopharm Oncology, Inc., Bayer AG, and LeoLabs, Inc., Dr. Schwartz has accumulated a number of successful new drug applications (NDAs), numerous investigational new drug (IND) applications, preclinical and clinical drug development programs. During his time in biotech, Dr. Schwartz acquired knowledge of investors relations, partnering and capital raising. Currently, in addition to the Infinity Board of Directors, Dr. Schwartz is a board member of Mereo Biopharma, Enlivex and Cyclacel pharmaceuticals and an advisor in different capacities to numerous biotech companies. Dr. Schwartz qualified as a medical doctor in South Africa followed by additional fellowship training in Canada.

    Infinity Pharmaceuticals, Inc. (NASDAQ:INFI) ("Infinity" or the "Company"), a clinical-stage biotechnology company developing eganelisib, a potentially first-in-class, oral, immuno-oncology macrophage reprogramming therapeutic which has been shown to reverse a fundamental biologic mechanism of immune suppression in cancer and activate an anti-tumor immune response, today presents data updates from MARIO-275, the Company's randomized, placebo-controlled Phase 2 study evaluating the efficacy and safety of eganelisib in combination with nivolumab (Opdivo®) in platinum-refractory, I/O naïve patients with advanced UC as well as data from MARIO-3, the Company's ongoing Phase 2 study evaluating eganelisib in a novel triple combination in the front-line setting with atezolizumab (Tecentriq®) and nab-paclitaxel (Abraxane®) in patients with unresectable locally advanced or metastatic TNBC.

    Adelene Perkins, Chief Executive Officer and Chair, Infinity Pharmaceuticals, said, "Today we report data indicating that eganelisib re-programs macrophages in the tumor microenvironment, turning pro-tumor, M2, macrophages into anti-tumor, M1, macrophages and improves outcomes for patients in two distinct types of cancer. Specifically, when combined with current standard of care therapies, the data showed that eganelisib increased overall survival in patients with metastatic urothelial cancer and prolonged progression free survival in patients with TNBC. These data provide preliminary, but compelling evidence of eganelisib's potential to improve outcomes for patients with these two types of cancer. Validation of the fundamental biologic hypothesis of eganelisib, and the resulting prospect of patient benefit, gives us great confidence in the future of eganelisib, Infinity and our ability to realize our vision of bringing better therapies to patients. In the months ahead, Infinity plans to work with investigators, key opinion leaders and regulatory authorities to carefully choose the most appropriate clinical paths forward and expects to provide an update by year end, together with an update on our maturing TNBC data."

    Brian Schwartz, M.D., consulting Chief Physician, Infinity Pharmaceuticals, said, "The promising survival benefit was noted after over a year of following MARIO-275 patients versus the control arm as well as compared to historical trials including CheckMate-275, particularly given the magnitude of the unmet need in 2L UC, including in the PD-L1 negative patient population. These results are reinforced by the progression free survival data which we presented at ASCO GU in February 2021 as well as the translational data that support our thesis that eganelisib reprograms macrophages in the tumor microenvironment and that validate eganelisib's mechanism of action. We believe overall survival represents a key registrational endpoint, and given these exciting new OS data, we are exploring the optimal study design for a potential registration study and expect to provide a program update by the end of 2021."

    Erika Hamilton, M.D., Director, Breast Cancer and Gynecologic Cancer Research Program, Tennessee Oncology, and Lead Study Investigator for MARIO-3, said, "The emerging progression free survival data from MARIO-3 are very encouraging and suggest that the impressive disease control rate observed, regardless of PD-L1 status, is translating to a benefit in progression free survival. These results are consistent with the results from MARIO-275, which show the similar translation of disease control into a meaningful survival benefit for patients. For patients with TNBC, the potential to extend progression free survival, regardless of PD-L1 status, would be a transformational breakthrough. We are on track to complete enrollment by year end, and with the majority of patients still on treatment, look forward to presenting additional, more mature data at that time."

    MARIO-275 Key Data Updates:

    • 49 patients were enrolled in the trial with the last patient enrolled in June 2020.
    • Median overall survival (mOS) in the intent to treat (ITT) population was 15.4 months (6.2, NE) on the eganelisib plus nivolumab combination arm as compared to 7.9 months (2.3, NE) on the control arm of nivolumab alone with a hazard ratio of 0.62 (0.28, 1.36), which reflects a 38% lower probability of death on the combination arm.
      • At the one-year landmark, 59% of patients in the ITT population receiving the eganelisib plus nivolumab combination remained alive, compared to 32% in the nivolumab control arm.
    • The mOS benefit observed in patients with PD-L1(-) tumors was the same as in the ITT population, with a mOS of 15.4 months (4.7, NE) on the eganelisib plus nivolumab combination arm as compared to 7.9 months (1.9, NE) on the control arm of nivolumab alone with a hazard ratio of 0.60 (0.21, 1.71), which reflects a 40% lower probability of death on the combination arm.
      • At the one-year landmark, 54% of the patients with PD-L1(-) tumors receiving the eganelisib plus nivolumab combination remained alive, compared to 17% in the nivolumab control arm.
    • The most common treatment emergent adverse events (TEAEs) across all doses, all causality, were pyrexia (33.3%), decreased appetite (30.3%), pruritus (27.3%), asthenia (27.3%), rash (27.3%), disease progression (27.3%) and increased alanine aminotransferase (24.2%); and the most common ≥Grade 3 TEAEs across all doses, all causality, were disease progression (27.3%), anemia (12.1%), and hepatic AEs including hepatotoxicity (15.2%), increased ALT (12.1%) and increased AST (12.1%) with no Hy's Law. No Grade 5 hepatic AEs were reported.
    • Translational data: Gene expression studies from peripheral blood, followed by gene set enrichment analysis using Hallmark gene signature sets show the pro-inflammatory interferon gamma and interferon alpha pathways were the most significantly enriched pathways in the combination arm when comparing Day 15 to baseline, regardless of PD-L1 status, with higher enrichment scores and lower p values than on the control arm. These data are consistent with eganelisib's mechanism of action which decreases immune suppression and increases immune activation.

    MARIO-3 Key Data Updates:

    • This data update includes 43 patients enrolled with 38 evaluable, which compares to 20 patients enrolled with 13 evaluable at our update at the San Antonio Breast Cancer Symposium in December 2020.
    • 86.8% (33/38) of evaluable patients demonstrated tumor reduction.
    • Disease control rate (DCR)
      • 78.2% (18/23) DCR in patients with PD-L1 negative tumors: complete response (CR) 0% (0/23), partial response (PR) 47.8% (11/23), stable disease (SD) 30.4% (7/23)
      • 91.7% (11/12) DCR in patients with PD-L1 positive tumors: CR 16.7% (2/12), PR 50% (6/12), SD 25% (3/12)
      • 84.2% (32/38) DCR in all patients: CR 5.3% (2/38), PR 50% (19/38), SD 28.9% (11/38)
    • Early progression free survival (PFS)
      • In patients with PD-L1(-) tumors, PFS was extended as compared to benchmark data for atezolizumab and nab-paclitaxel alone, increasing from 5.6 months to 7.3 months (3.5, NA).
      • In patients with PD-L1(+) tumors, PFS was extended as compared to benchmark data for atezolizumab and nab-paclitaxel alone, increasing from 7.5 to 11.2 months (5.3, 11.2).
      • In the ITT population, PFS was extended as compared to benchmark data for atezolizumab and nab-paclitaxel alone, increasing from 7.2 months to 7.4 months (5.3, NA).
    • MARIO-3 did not demonstrate any new or additive safety signals compared to benchmark trials. The most common TEAEs, all causality, were nausea (51.2%), fatigue (48.8%), alopecia (32.6%), diarrhea (32.6%), rash maculo-papular (30.2%) increased ALT (27.9%) with only one Grade 4 and increased AST (25.6%) with one grade 4. No Hy's Law or Grade 5 hepatic AEs were reported, and only one patient permanently discontinued study treatment due to an elevated liver function test.
    • Quantification across 11 paired tumor biopsies shows increased immune activation and decreased immune suppression including an increase in CD8+ T cells, activated T cells, and anti-tumor M1 macrophages and a decrease in tumor cells and pro-tumor M2 macrophages resulting in an increase in the M1:M2 ratio.
    • Paired tumor biopsy data show 5 of 8 patients with PD-L1(-) tumors converting to PD-L1(+) two months after treatment utilizing the 1% PD-L1 cutoff standard. PD-L1 expression also increased in the three patients with PD-L1(+) tumors who started the study above the 1% cutoff. None of the patients converting to PD-L1(+) or patients with PD-L1(+) tumors who experienced increased PD-L1 expression had disease progression.

    About Infinity and Eganelisib

    Infinity is an innovative biopharmaceutical company dedicated to advancing novel medicines for people with cancer. Infinity is advancing eganelisib, a first-in-class, oral immuno-oncology development candidate that selectively inhibits PI3K-gamma, in multiple clinical studies. MARIO-275 is a global, randomized, controlled combination study of eganelisib combined with Opdivo® in I/O naïve urothelial cancer. MARIO-3 is the first eganelisib combination study in front-line advanced cancer patients and is evaluating eganelisib in combination with Tecentriq® and Abraxane® in front-line TNBC and in combination with Tecentriq and Avastin® in front-line RCC. In collaboration with Arcus Biosciences, Infinity is evaluating a checkpoint inhibitor-free, novel combination regimen of eganelisib plus etrumadenant (AB928, a dual adenosine receptor antagonist) plus Doxil® in advanced TNBC patients. In 2019, Infinity completed enrollment in MARIO-1, a Phase 1/1b study evaluating eganelisib as a monotherapy and in combination with Opdivo (nivolumab) in patients with advanced solid tumors including patients refractory to checkpoint inhibitor therapy. With these studies Infinity is evaluating eganelisib in the anti-PD-1 refractory, I/O-naïve, and front-line settings.
