Presentation Title: A Phase 1 Study of the Oral CDK9 Inhibitor Voruciclib in Relapsed/Refractory (R/R) B-Cell Lymphoma (NHL) or Acute Myeloid Leukemia (AML)
Session Title: Acute Myeloid Leukemias: Investigational Therapies, Excluding Transplantation and Cellular Immunotherapies: Poster III (616)
Presenter: Mathew Davids, MD, MMSc., Director, Clinical Research, Division of Lymphoma, Dana Farber Cancer Institute
Date: Monday, December 11, 2023, 6:00-8:00 PM (Pacific Time)
Publication Number: 4286

About the Phase 1 Study

The Phase 1 study is a two stage, open-label, 3+3 dose escalation and expansion study evaluating voruciclib, a CDK9 inhibitor, as a monotherapy and in combination with venetoclax (marketed as Venclexta), a BCL2 inhibitor. Inhibition of CDK9 blocks the production of Mcl-1, which is an established resistance mechanism to the BCL2 inhibitor venetoclax. The primary objectives of the study are to determine the safety and biologic effective dose of voruciclib monotherapy or voruciclib in combination with venetoclax. Secondary objectives of the study include assessing the preliminary efficacy, pharmacokinetics, pharmacodynamics, and biomarkers of voruciclib monotherapy or voruciclib in combination with venetoclax.

The first stage of the study, evaluating the dose and schedule of voruciclib as a single-agent in patients with relapsed and refractory ("R/R") acute myeloid leukemia ("AML") or B-cell malignances after failure of standard therapies, is now completed and the final results presented in the abstract. Stage 2 of the study is evaluating voruciclib in combination with standard dose venetoclax in patients with R/R AML.

About Voruciclib

Voruciclib is an orally administered cyclin-dependent kinase 9 ("CDK9") inhibitor with potential to treat both hematological malignancies and solid tumors. It is in clinical development for acute myeloid leukemia and B-cell malignancies. Applications in solid tumors are also being considered.

The CDK family of proteins are important cell cycle regulators responsible for the control of cell proliferation, differentiation, apoptosis, and DNA repair. CDK9, one of several members of the CDK family of proteins, functions as a gene transcription controller and is also involved in regulating protein degradation. Specifically, CDK9 is a promising target to treat a range of cancers because of its role in controlling two other proteins often dysregulated in cancerous cells: myeloid leukemia cell differentiation protein ("Mcl-1") and the MYC proto-oncogene protein ("MYC")

Mcl-1 is a member of the family of anti-apoptotic proteins which, when elevated, may prevent the cell from undergoing cell death. Inhibition of CDK9 blocks the production of Mcl-1, which is an established resistance mechanism to the B-cell lymphoma 2 ("BCL2") inhibitor venetoclax (marketed as Venclexta).

MYC regulates cell proliferation and growth. Upregulation of MYC is implicated in many human cancers and is frequently associated with poor prognosis and unfavorable patient survival. CDK9, in addition to being a transcription factor for MYC, also decreases phosphorylation of MYC protein that is implicated in stabilizing MYC in KRAS mutant cancers. Targeting MYC directly has historically been difficult, but CDK9 is a promising approach to target this oncogene.

"There is a high unmet need for solid tumor cancer treatments. I am excited to be an Investigator with the BASECAMP-1 pre-screening study, which identifies patients early in their clinical course for treatment with A2 Bio’s novel cell therapy platform," said Diane Simeone, M.D., Laura and Isaac Perlmutter Professor of Surgery at NYU.

"BASECAMP-1 provides patients an early opportunity to be identified and triaged to the appropriate EVEREST logic-gate Tmod CAR T trial. BASECAMP-1 is an innovative approach to preserve T cells for subsequent CAR-T manufacturing, in a patient’s clinical course before they are exposed to extensive chemotherapy," said William Go, M.D., Ph.D., Chief Medical Officer of A2 Bio.

BASECAMP-1 is a novel pre-screening protocol to identify a diverse set of patients with the genetic loss of HLA-A*02 in solid tumors, which is required to enroll in A2 Bio interventional trials.

A2 Bio has partnered with Tempus, a leader in precision medicine, to bring the latest technology to patient screening. In BASECAMP-1, tumor tissue of patients at A2 clinical sites is tested through Tempus’ xT NGS diagnostic to identify patients with permanent genetic loss of HLA-A*02 in their tumors. In addition, Tempus connects patients with HLA loss screened through standard of care to A2 clinical investigators through the AWARE program.

Once eligibility is met, patients from BASECAMP-1 can be leukapheresed with their cells stored for future manufacturing for a current or future A2 Bio interventional trial. BASECAMP-1 is open at 13 sites across the United States.

EVEREST-1 (NCT05736731) is a seamless Phase 1/2 study for A2B530, the first autologous logic-gated cell therapy developed from A2 Bio’s proprietary Tmod platform. The Tmod platform utilizes a dual-receptor design consisting of an activator that targets tumor cells and a blocker that protects normal cells. A2B530 consists of an activator that targets carcinoembryonic antigen (CEA) and a blocker that targets HLA-A*02.

The EVEREST-1 poster will highlight the study design for A2B530, which is actively dosing patients with pancreatic, colorectal and lung cancers. If a patient is ready for treatment, A2B530 can be manufactured for a patient from their apheresis that has already been collected and stored at A2 Bio via the BASECAMP-1 study. EVEREST-1 is open at 8 sites across the United States.

EVEREST-2 (NCT06051695), A2 Bio’s second clinical program, is a seamless Phase 1/2 study for A2B694, which targets mesothelin (MSLN) with a blocker that targets HLA-A*02. Patients with pancreatic, lung, colorectal, ovarian and mesothelioma are currently being pre-screened through the BASECAMP-1 study.

About A2B530

A2B530 consists of an activator that targets carcinoembryonic antigen (CEA) and a blocker that targets HLA-A*02. CEA is a tumor-associated antigen expressed at high levels in colorectal, pancreatic and non-small cell lung cancers, but also in healthy gut tissues. HLA-A*02 is expressed in normal tissues and permanently lost via genetic deletion in tumor tissues in the patient population eligible for EVEREST-1. A2B530’s dual-receptor design is intended to provide selective killing of tumor tissues that express CEA and have lost the HLA-A*02 gene permanently.

About A2B694

A2B694 consists of an activator that targets mesothelin (MSLN) and a blocker that targets HLA-A*02. MSLN is a tumor-associated antigen expressed at high levels in mesothelioma, ovarian, colorectal, pancreatic, and non-small cell lung cancers, but also in healthy tissue such as the lining of the heart and lung. HLA-A*02 is expressed in normal tissues and permanently lost via genetic deletion in tumor tissues in the patient population eligible for EVEREST-2. A2B694’s dual-receptor design is intended to provide selective killing of tumor tissues that express MSLN and have lost the HLA-A*02 gene permanently.

About OMS906

OMS906 is an investigational human monoclonal antibody targeting mannan-binding lectin-associated serine protease-3 (MASP-3), the key activator of the complement system’s alternative pathway. The complement system plays a central role in inflammation and becomes activated as a result of tissue damage or microbial infection. Responsible for the conversion of pro-complement factor D to complement factor D, MASP-3 is believed to be the premier target in the alternative pathway – it has the lowest native circulating level and low relative clearance compared to the other alternative pathway proteins and, unlike C5 and C3 blockers, MASP-3 inhibition leaves intact the lytic arm of the classical pathway, important for fighting infection. Also, unlike other components of the alternative pathway, MASP-3 is believed not to be an acute phase reactant, which could provide a significant advantage to MASP-3 inhibitors, like OMS906, over other alternative pathway inhibitors. MASP-3 inhibitors are thought to have preventive or therapeutic effects across a broad range of diseases including paroxysmal nocturnal hemoglobinuria (PNH), hemolytic uremic syndrome (HUS), atypical HUS, traumatic brain injury, arthritis, wet age-related macular degeneration, ischemia-reperfusion injury, transplant-related complications and other immune-related disorders.
