Bellicum Pharmaceuticals Provides Operational Update and Reports Financial Results for the Fourth Quarter and Year Ended December 31, 2018

HOUSTON, March 12, 2019 (GLOBE NEWSWIRE) -- Bellicum Pharmaceuticals, Inc. (NASDAQ:BLCM), a leader in developing novel, controllable cellular immunotherapies for cancers and orphan inherited blood disorders, today reported financial results for the fourth quarter and full year ended December 31, 2018.

“We believe that Bellicum is well-positioned for an exciting and eventful 2019 as a result of our investments to strengthen our clinical development and executive teams over the past 24 months,” said Bellicum’s President & CEO Rick Fair. “Based on promising preclinical and initial clinical data on BPX-601, we have prioritized GoCAR-T^® candidates incorporating our iMC activation switch in our clinical development strategy. In addition to progressing our Phase 1/2 trial of BPX-601, we intend to submit IND applications for two novel, dual-switch GoCAR-T clinical programs in 2019. For rivo-cel™, we anticipate topline Phase 2 results in pediatric patients in the second quarter of 2019, which will form the basis for European Marketing Authorisation Application (MAA) submissions planned for late 2019.”

PROGRAM HIGHLIGHTS AND CURRENT UPDATES

Bellicum Advances and Expands Clinical Program for GoCAR-T Platform

BPX-601

• Bellicum completed enrollment in the dose-escalation portion of its ongoing Phase 1/2 study of BPX-601 in patients with advanced pancreatic cancer expressing prostate stem cell antigen (PSCA). Bellicum presented positive initial clinical data from Part 1 of the study at the ESMO Immuno-Oncology Congress in December 2018 and the Gastrointestinal Cancers Symposium in January 2019 that showed a promising safety profile. In several patients reported, enhanced cell expansion, prolonged cell persistence, and early evidence of clinical activity and disease control were observed. The trial protocol has been amended to add the complete lymphodepletion conditioning regimen cyclophosphamide/fludarabine (Cy/Flu) and to include patients with gastric and prostate cancers. Once this safety cohort has been completed, Bellicum plans to incorporate an additional cohort to evaluate repeat rimiducid dosing to re-activate iMC over time, which is intended to deepen and extend the treatment effect. Initial results from these cohorts are expected in 2019.

Controllable Dual-Switch Candidates

• BPX-603 is Bellicum’s first controllable dual-switch GoCAR-T product candidate, which incorporates both the iMC activation switch and the CaspaCIDe^® safety switch. BPX-603 is designed to target solid tumors that express the human epidermal growth factor receptor 2 antigen (HER2). HER2 is a validated antigen for cancer therapies, and academic CAR-T cell clinical studies have shown evidence of antitumor activity. These CAR-T approaches targeting HER2 have been limited by modest clinical efficacy and off-tumor/on-target toxicity. Bellicum believes that its dual-switch GoCAR-T technology may be uniquely suited to improve upon these earlier efforts by driving greater efficacy through iMC activation while enabling clinicians to manage any treatment-emergent toxicities with CaspaCIDe. Bellicum expects to submit an IND application for BPX-603 and to initiate a clinical trial in 2019.
• BPX-802 is a dual-switch GoCAR-T product candidate targeting an antigen expressed in hematological malignancies. Bellicum expects to submit an IND application for BPX-802 in late 2019.

Company Prepares for Rivo-cel Registration in E.U. for Pediatric Patients and Initiates Global Trial for Adult and Adolescent Patients

• Bellicum presented late interim analyses of the pediatric study BP-004 at ASH in December 2018. The results demonstrated that 90.9% of rivo-cel treated patients experienced Event Free Survival (EFS) at 180 days compared to 87.7% of patients undergoing matched unrelated donor (MUD) HSCT. Non-inferiority on EFS versus MUD HSCT is the primary endpoint for European regulatory review. The results also demonstrated that rivo-cel treated patients had high rates of relapse-free (82.9%) and overall (94.4%) survival with a median follow up of 20 months. Lastly, the results demonstrated a best overall response rate of 70% in patients that developed advanced or steroid-refractory GvHD when treated with rimiducid, with the majority being complete responses.
• The Company expects topline results from the BP-004 study in the second quarter of 2019 and intends to submit MAAs for rivo-cel and rimiducid in late 2019.
• The Company recently initiated THRIVE, a pivotal randomized global Phase 2/3 clinical trial of rivo-cel in adult and adolescent patients 12 years and older with intermediate- and high-risk acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS). In the Phase 3 portion of the trial, patients will be randomized to receive either a/b T cell and B-cell depleted haploidentical HSCT plus rivo-cel without GvHD prophylaxis, or a haploidentical HSCT followed by cyclophosphamide post-transplant, commonly referred to as the “Baltimore regimen,” which is the current standard of care for haplo-HSCT in the U.S. and Europe.

About BPX-601

BPX-601, the Company’s first GoCAR-T^® product candidate, incorporates iMC, Bellicum’s inducible co-activation domain. iMC (inducible MyD88/CD40) is designed to provide a powerful boost to T cell proliferation and persistence, and enable the CAR-T to override key immune inhibitory mechanisms, including PD-1 and TGF-beta. BPX-601 is being evaluated as a treatment for solid tumors expressing prostate stem cell antigen (PSCA), including pancreatic, gastric, and prostate cancers.

About Rivo-cel (BPX-501)

Rivo-cel™ (rivogenlecleucel) is an allogeneic polyclonal T-cell product designed to accelerate immune recovery after HSCT and to reduce relapse of leukemia following a stem cell transplant. The cell treatment contains a diverse repertoire of T cells which may contribute to a robust graft vs. leukemia effect. Rivo-cel’s anti-infective benefits may also reduce morbidity and mortality, as patients are highly susceptible to infection following a transplant. The product’s CaspaCIDe^® safety switch enables this approach by allowing physicians to reduce the number of alloreactive cells in the event of uncontrolled GvHD. Rivo-cel addresses a major unmet need in adult and pediatric leukemia, lymphoma and inherited blood disease patients following a haploidentical stem cell transplant.

About Bellicum Pharmaceuticals
