The oral presentation outlines OPTIMIZE-1, an open-label, multicenter, Phase 1b/2 study, assessing the safety and efficacy of mitazalimab (CD40 mAb agonist) in combination with standard of care chemotherapy mFOLFIRINOX. The trial study met its primary endpoint, with mitazalimab showing a manageable safety profile and promising DoR associated with a clinically meaningful survival benefit.

Furthermore, there was a significant correlation between treatment-induced increases in natural killer T (NKT) cells and T cells expressing CD38 and depth of response, strongly suggestive of a mitazalimab-dependent contribution to deep anti-tumor responses.

The 5-year overall survival rate for metastatic pancreatic ductal adenocarcinoma (mPDAC) is less than 5%, and current systemic therapies are associated with poor outcomes. The OPTIMIZE-1 data have also recently been published in the peer-reviewed The Lancet Oncology and presented in two posters at the 2024 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting.

Alligator expects to report 18-month survival follow-up data from OPTIMIZE-1 at the end of June 2024, and that these will provide further insights into the potential of mitazalimab.

"We are pleased to present these exciting results with mitazalimab to the scientific community at ESMO (Free ESMO Whitepaper) GI. It is an important validation of the potential of our product candidate to make a meaningful difference to pancreatic cancer patients, who currently have a very poor prognosis and limited treatment options," said Dr. Sumeet Ambarkhane, CMO of Alligator Bioscience. "In particular, the long-lasting responses and related biomarker associations reported in OPTIMIZE-1 demonstrate a critical immunomodulatory contribution of mitazalimab. The increase in ORR and PFS, compared to FOLFIRINOX alone, are superior outcomes and mitazalimab also showed a favorable safety profile. Taken as a whole, these are very encouraging data which form the basis of planning mitazalimab’s development in a randomized Phase 3 study."
About the OPTIMIZE-1 data
Results from the OPTIMIZE-1 trial showed mitazalimab in combination with mFOLFIRINOX had a confirmed ORR of 40.4% in 57 evaluable patients (unconfirmed ORR was 50.9%). Median DoR was 12.5 months and the median OS was 14.3 months. Median Progression Free Survival (PFS) was 7.7 months. These data compare favorably to the historically reported outcomes with FOLFIRINOX (ORR 31.6%, mDoR 5.9 months, mOS 11.1 months and mPFS 6.4 months)[1]. The recently approved new treatment regimen of NALIRIFOX was associated with an ORR of 42%, mDoR of 7.3 months, mPFS 7.4 months and a mOS of 11.1 months[2].

About pancreatic cancer
Pancreatic cancer is the 12th largest cancer by number of patients. It is expected to become the second leading cause of cancer death in the western world by 2030. There are about 200,000 annual cases in the U.S. and the EU, with very poor prognosis: five-year survival is about 10% and median survival about 6 months. For 80% of patients, the only option is chemotherapy that offers only marginal benefit. FOLFIRINOX is expected to be the preferred first line regimen in the U.S. and the EU for patients with good performance status.

"The transformative impact that the ALPHA3 trial could have on the treatment of first line LBCL is hard to overstate," said David Chang, M.D., Ph.D., President, Chief Executive Officer and Co-Founder of Allogene. "Our investigational allogeneic CAR T product is designed to eliminate the complex logistics that have hindered autologous CAR T adoption to date and open the door for access by doctors in the community setting. ALPHA3 will proactively offer this potentially curative modality only to those patients who are likely to relapse."

The ALPHA3 trial will screen patients who are likely to relapse after 1L treatment for enrollment in the trial by using the Foresight CLARITY Investigational Use Only (IUO) MRD test, powered by PhasED-Seq, which recently received Investigational Device Exemption (IDE) approval from the U.S. Food and Drug Administration (FDA). Leveraging CLARITY’s ultra-sensitive MRD technology, cema-cel will be administered as a one-time infusion immediately upon detection of MRD at the completion of six cycles of R-CHOP or other standard 1L chemoimmunotherapy regimen. When given as a "7th cycle" of frontline treatment to eligible patients with MRD, consolidation treatment with cema-cel has the potential to meaningfully improve 1L cure rates in LBCL.

"Following the FDA Advisory Committee’s recent recommendation to include MRD as an endpoint to accelerate clinical trials in multiple myeloma, the ALPHA3 trial is yet another step forward towards broader implementation of MRD detection in drug development and clinical decision making," said Dr. Sandra Close, Chief Operating and Compliance Officer at Foresight Diagnostics. "We believe the Foresight CLARITY MRD platform has the performance to enable actionable treatment decisions at end of therapy when residual disease levels are challenging to detect using conventional methods."

The ALPHA3 trial will be conducted in a wide array of cancer treatment centers, including community cancer centers where most earlier line patients seek care. This randomized study will enroll approximately 240 patients and is designed to demonstrate a meaningful improvement in event free survival (EFS) in patients treated with cema-cel relative to patients who receive the current standard of care (observation). Efficacy analyses are expected to occur in 2026 and will include an interim EFS analysis monitored by the independent Data Safety Monitoring Board (DSMB) in 1H 2026 and the data readout of the primary EFS analysis in 2H 2026 with a potential biologics license application (BLA) submission targeted for 2027.

About Cemacabtagene Ansegedleucel (cema-cel)
Cemacabtagene ansegedleucel, or cema-cel is a next generation anti-CD19 AlloCAR T investigational product for the treatment of large B cell lymphoma (LBCL). In June 2022, the U.S. Food and Drug Administration granted Regenerative Medicine Advanced Therapy (RMAT) designation to cema-cel in third line (3L) r/r LBCL. The ALPHA3 pivotal Phase 2 trial in first line (1L) consolidation for the treatment of LBCL launched in June 2024. Allogene has oncology rights to cema-cel in the US, EU and UK with options for rights in China and Japan.

About the ALPHA3 Trial
Over 60,000 patients are expected to be treated for LBCL annually in the US, the EU and the UK. While first line (1L) R-CHOP or other chemoimmunotherapy is effective for most patients, approximately 30% will relapse and require subsequent treatment. The current standard of care (SOC) after 1L treatment has been simply to "watch and wait" to see if the disease relapses. The pivotal Phase 2 ALPHA3 study takes advantage of cema-cel as a one-time, off-the-shelf treatment that can be administered immediately upon discovery of MRD following six cycles of R-CHOP or other chemoimmunotherapy, positioning it to become the standard "7th cycle" of frontline treatment available to all eligible patients with MRD.

On June 20, 2024 Escend Pharmaceuticals, Inc., a privately held oncology company, reported a poster presentation with initial data from the Australasian Leukaemia and Lymphoma Group’s (ALLG) investigator-initiated Phase I/II platform study (MYDAS-T MDS05 domain 1) evaluating ES-3000 alone and in combination with ASTX727 at European Hematology Association (EHA) (Free EHA Whitepaper) (EHS) in Madrid, Spain (Press release, Escend Pharmaceuticals, JUN 20, 2024, View Source [SID1234644464]).

The poster is entitled, ‘Combining oral Wnt/β catenin/inflammasome pathway inhibitor, a bis-benzylisoquinoline alkaloid (ES-3000) with oral decitabine/cedazuridine (ASTX727)* as a treatment strategy for myelodysplasia’. The primary objectives of the initial phase of the trial are to assess the safety profile of ES-3000 and determine the recommended phase 2 dose and dosing schedule of ES-3000 in combination with fixed-dose decitabine/cedazuridine (ASTX727). The results indicate a response in 40% of evaluable patients who received ES-3000 as a single agent. The dose-limiting toxicities as per BION modeling allowed the study to dose escalate.

The current agreement lasts for one year with an opportunity for Astellas to extend to two years.

Alexander disease is an ultra-rare and progressive central nervous system (CNS) disorder caused by mutations in the glial fibrillary acidic protein (GFAP) gene that usually has a fatal outcome. Most affected patients do not live beyond their first few years. Alexander disease affects astrocytes, a type of cell that makes up the majority of cells in the CNS and leads to the destruction of white matter in the brain, causing progressively worsening severe intellectual and physical disabilities; and eventually affected individuals will lose life-sustaining abilities.1

Yoshitsugu Shitaka, Ph.D., Chief Scientific Officer at Astellas

"We are pleased to partner with UMass Chan, a leading medical academic center in Massachusetts, and help foster innovation in this important ecosystem. At Astellas, we strive to find innovative ways to treat patients with the highest unmet medical needs, who have traditionally been left behind, including rare and ultra-rare diseases.

Gene therapy is a complex breakthrough area where traditional approaches might not be sufficient or optimal, and ultra-rare diseases like Alexander disease cannot be appropriately addressed with the usual pharma models. Only by working alongside all the key players such as patients, physicians, academic centers, can we advance pioneering work to challenge the status quo, by turning innovative science into meaningful treatments for those patients who are waiting."

The sponsored research agreement supports investigations being done by Jun Xie, PhD, associate professor of microbiology & physiological systems, and Guangping Gao, PhD, the Penelope Booth Rockwell Professor in Biomedical Research, professor of microbiology & physiological systems, director of the Horae Gene Therapy Center and co-director of the Li Weibo Institute for Rare Diseases Research at UMass Chan, who have developed an adeno-associated virus vector that can express a small RNA silencer that suppresses the mutant proteins that cause AxD in mice.
