On November 11, 2021 Gamida Cell Ltd. (Nasdaq: GMDA), an advanced cell therapy company committed to cures for cancer and other serious diseases, reported that completed a Type B Pre-Biologics License Application (BLA) meeting with the U.S. Food and Drug Administration (FDA) for omidubicel, a potentially life-saving treatment for patients with blood cancers in need of stem cell transplant (Press release, Gamida Cell, NOV 11, 2021, View Source [SID1234595304]). The FDA requested that Gamida Cell provide revised analysis of the manufacturing data generated at Gamida Cell’s wholly-owned commercial manufacturing facility to demonstrate the comparability to the omidubicel that was produced at the clinical manufacturing sites for the Phase 3 study. The FDA did not request additional clinical data to initiate the BLA submission once analytical comparability is demonstrated. The company will continue to work collaboratively with the FDA and anticipates submitting the BLA in the first half of 2022 in lieu of the company’s previous plan to submit the BLA by the end of 2021.

"Despite the delay in timing to bring omidubicel to patients after a potential FDA approval, we are encouraged by the FDA’s reaction to our Phase 3 data as the pivotal trial of omidubicel. We have gained further clarity with the FDA on the requirements for demonstrating comparability for our commercial manufacturing facility," said Julian Adams, Ph.D., Chief Executive Officer of Gamida Cell. "With the FDA’s feedback in hand, we believe that we are one step closer for omidubicel to be made available to patients in need."

Omidubicel, an investigational advanced cell therapy for allogeneic bone marrow transplant

Omidubicel is the foundational product based on Gamida Cell’s proprietary NAM-enabled cell expansion technology. It is the first cell therapy for bone marrow transplant to receive Breakthrough Therapy Designation from the FDA. The BLA submission will be based on the results of an international, randomized Phase 3 study of omidubicel that was designed to evaluate the safety and efficacy of omidubicel in patients with hematologic malignancies undergoing a bone marrow transplant compared to patients who received a standard umbilical cord blood transplant. The study achieved its primary endpoint, a statistically significant reduction in time to neutrophil engraftment, as well as all key secondary endpoints. A key milestone in a patient’s recovery, neutrophil engraftment is a measure of how quickly the stem cells a patient receives in a bone marrow transplant are established and begin to make healthy new cells. In the Phase 3 study, the median time to neutrophil engraftment was 12 days for patients randomized to omidubicel compared to 22 days for the comparator group (p < 0.001). Additionally, the study met key secondary endpoints related to the speed of platelet engraftment, decrease in infections and reduction in hospitalizations, all significant clinical measures in bone marrow transplant.

Acrivon’s Predictive Precision Proteomics (AP3) technology platform enables the development of drug-tailored OncoSignature companion diagnostics that link drug mechanisms to the active disease-driving processes of cancer in patients, uncovering drug sensitivity not achievable through traditional genomics analyses. Acrivon’s pipeline will be advanced in clinical trials selectively enrolling patients predicted to benefit from treatment based on its proprietary OncoSignature companion diagnostics. The company’s clinically advanced lead product candidate ACR-368 (also known as prexasertib, in-licensed from Eli Lilly and Company) is a potent, second generation CHK1/2 inhibitor which has shown durable, single-agent anticancer activity, including complete responses, in a proportion of patients across multiple cancers in Phase 2 studies.

"On the heels of the company’s recent public launch in late June, we are pleased to have attracted a top-tier syndicate of leading private/public investors that recognize the transformative potential of our platform and pipeline," said Peter Blume-Jensen, M.D., Ph.D., chief executive officer and founder of Acrivon. "Appropriate patient selection is one of the biggest unmet needs for targeted oncology therapeutics and is currently not possible for the majority of common solid cancers. We are excited to now leverage the broader potential of our AP3 platform, which enables us to decipher a drug’s true mechanism-of-action at high resolution and accurately match that with the disease-driving processes in a patient’s tumor. This allows us to not only predict individual patient response, but also identify new indications and rational drug combinations, as well as hurdles that block patient responses, such as resistance mechanisms. The initial application of our technology is for the development of ACR-368 and two other undisclosed pipeline programs targeting solid tumors."

Derek DiRocco, Ph.D., partner at RA Capital and member of the board added, "Acrivon’s lead asset ACR-368 has demonstrated impressive monotherapy activity in several cancers, and the late-stage Phase 2 development strategy using their proprietary patient selection methodology can lead to multiple accelerated approval opportunities in these high unmet need cancers. We are impressed by the company’s foundational technologies and believe they are broadly applicable to therapeutics beyond ACR-368 and have the potential to usher in a new era of precision-based medicine beyond the industry’s current approaches, which are largely limited to the use of genomic biomarkers."

"We are thrilled by the support from these notable investors," said Kristina Masson, Ph.D., co-founder and site head of Acrivon AB, Acrivon’s phospho-proteomic and drug discovery hub located in Medicon Village, Lund, Sweden. "We have strategically built our phospho-proteomics capabilities here to leverage the proximity to our academic co-founder, professor Jesper Olsen at the University of Copenhagen, Denmark, who is a recognized leader in the field of phospho-proteomics. Likewise, our structure-guided drug discovery programs benefit from local expertise in structural biology and medicinal chemistry. The excellent infrastructure and world-leading proteomics expertise established at our hub in Scandinavia remains a major competitive advantage for Acrivon, and we are excited to also welcome several European investors to join our investor syndicate."

About Acrivon Precision Predictive Proteomics
Acrivon Predictive Precision Proteomics, AP3, is a proprietary, streamlined approach to develop patient selection tumor biopsy tests, called OncoSignature tests. The technology is engineered to be agnostic to underlying genetic alterations and enables identification and treatment of the patients whose tumors are regulated by and sensitive to the drug based on direct protein measurement of the critical tumor-driving mechanisms. The AP3 approach leverages unbiased differential global phosphoproteomic drug profiling using mass spectrometry, biased tumor model analyses, and quantitative multispectral in situ imaging of patient derived xenograft (PDX) in vivo models and intended-use tumor samples and clinical trial biopsies, to identify and evaluate biomarkers. The output of AP3 is clinically actionable, drug-tailored, proprietary OncoSignature tests. These are automated, quantitative protein multiplex imaging tests applied to pretreatment tumor biopsies as a companion diagnostic (CDx) to select and treat the patients predicted to benefit from the drug. The AP3 method is broadly applicable across drugs and is a transformative, efficient method to accurately match the right therapy to the right patient.

About ACR-368 (also known as prexasertib)
ACR-368 is a potent, selective inhibitor of CHK1 and CHK2 which has shown deep durable single agent activity, including complete responses, in a proportion of patients across several Phase 2 studies of platinum-resistant ovarian cancer and in squamous cell cancers, including anal cancer for which FDA has granted orphan drug designation. ACR-368 has been tested in >1,000 patients as monotherapy and in combination, showing excellent pharmacokinetic and pharmacological properties and a favorable safety profile at the recommended Phase 2 dose across monotherapy studies. Acrivon has obtained exclusive, world-wide rights to develop and commercialize ACR-368 under a license agreement with Eli Lilly and Company.

Poster #795 entitled, "APVO603: A dual 4-1BB and OX40 bispecific approach utilizing ADAPTIR technology designed to deliver a conditional T cell/NK response against solid tumors," will be presented and displayed on-site on Saturday, November 13th in Washington, D.C. Data in the poster showed that APVO603 enhanced dose-dependent control of in vitro tumor cell lysis when paired with a bispecific T-cell engager when compared either alone. Of note, investigators show that APVO603 has minimal impact on regulatory T cell suppression of CD8+ T cells’ proliferation in vitro.

"APVO603 is a differentiated bispecific antibody with the potential to leverage the benefits of 4-1BB and OX40 in a single agent. Further, the tethering of molecules has the potential to reduce safety risks and improve potency profiles by targeting responses specifically to sites of active inflammation and limiting on-target toxicity," said Hilario Ramos, Senior Director of Immunobiology at Aptevo. "In addition, the data presented here demonstrate that this combination has the potential to promote anti-tumor responses two-fold. First, by improving the fitness of exhausted effector CD8+ T cells. Second, by reducing the potential for activation of suppressive responses by T regulatory subsets. This dual biological mechanism of action offers the potential for development of a compound that acts against both solid and hematologic tumors and in the presence of addition immunomodulatory treatments or modalities such as CAR T or adoptive immune cell therapies."

Aptevo CEO Marvin White commented, "We are very encouraged by the results reported in this poster, and we are excited to continue to develop APVO603 and provide this update on our progress as we work to advance the compound."
