"We are pleased FDA has granted Breakthrough Therapy designation for IMGN632, our novel CD123-targeted ADC, as it underscores the urgent need for effective and well-tolerated treatments for patients with this rare and aggressive cancer," said Mark Enyedy, ImmunoGen’s President and Chief Executive Officer. "We look forward to continuing to work with FDA to further define the development path for IMGN632 in BPDCN, in addition to pursuing our ongoing evaluation of IMGN632 in AML and other hematological malignancies."

According to FDA guidelines, Breakthrough Therapy designation is designed to expedite the development and review of drugs that are intended to treat a serious condition and have generated preliminary clinical evidence that the drug may demonstrate substantial improvement over available therapy. Breakthrough Therapy designation was granted for IMGN632 based on the findings from the BPDCN cohort of the first-in-human study of IMGN632, for which initial data were presented in an oral session at the American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting in 2019. Updated data from the IMGN632 monotherapy BPDCN dose expansion cohort will be presented at ASH (Free ASH Whitepaper) this December.

ABOUT IMGN632
IMGN632 is a CD123-targeting ADC in clinical development for hematological malignancies, including blastic plasmacytoid dendritic cell neoplasm (BPDCN), acute myeloid leukemia (AML), and acute lymphocytic leukemia (ALL). IMGN632 is currently being evaluated in multiple cohorts, including monotherapy for patients with BPDCN and minimal residual disease positive (MRD+) AML following frontline induction therapy and in combinations with Vidaza (azacitidine) and Venclexta (venetoclax) for patients with relapsed/refractory AML. IMGN632 uses one of ImmunoGen’s novel indolino-benzodiazepine (IGN) payloads, which alkylate DNA without crosslinking. IGNs have been designed to have high potency against AML blasts, while demonstrating less toxicity to normal marrow progenitors than other DNA-targeting payloads.

ABOUT BLASTIC PLASMACYTOID DENDRITIC CELL NEOPLASM
BPDCN is a rare form of blood cancer that has features of both leukemia and lymphoma, with characteristic skin lesions, lymph node involvement, and frequent spread to the bone marrow. This aggressive cancer requires intense treatment often followed by stem cell transplant. Despite the recent approval of a CD123-targeting therapy, the unmet need remains high for patients, particularly in the relapsed/refractory setting.

PLX9486 + Sunitinib Combination data to be presented in Oral CTOS Abstract

Cogent’s lead precision therapy is PLX9486, a potent and selective precision kinase inhibitor that is designed to target KIT mutations present in Systemic Mastocytosis and GIST. New details of the open-label Phase 1/2 clinical study testing the combination of PLX9486 with sunitinib in 18 adult patients with advanced GIST, will be presented as an oral presentation at the upcoming 2020 CTOS Annual Meeting.

Title: The Potent and Selective Kit Inhibitor PLX9486 Dosed in Combination with Sunitinib Demonstrates Promising Progression Free Survival (PFS) in Patients with Advanced Gastrointestinal Stromal Tumor (GIST): Final Results of a Phase 1/2 Study

Date: Friday, November 20, 2020 from 11:30 a.m. – 12:30 p.m. ET

Presenter: Jonathan Trent, M.D., Ph.D., University of Miami Health System, Sylvester Comprehensive Cancer Center

The oral presentation will contain detailed results from the combination of PLX9486 and sunitinib in patients with advanced GIST. Previously announced topline results demonstrated 11 months median progression free survival with the combination of PLX9486 and sunitinib in heavily treatment-experienced patients with advanced GIST, with two-thirds of patients having previously received three or more lines of therapy. PLX9486 was well-tolerated, and the most commonly occurring treatment emergent adverse events (TEAEs) were predominantly £ Grade 2. PLX9486 has been dosed in more than 50 patients both as a single agent and as part of a combination therapy. Based on the data, Cogent believes the combination of PLX9486 and sunitinib has the potential to address an unmet medical need in patients living with GIST.

About AO-176

AO-176 is a humanized anti-CD47 IgG2 antibody with a potential best-in-class profile. AO-176 is highly differentiated, with the potential to improve upon the safety and efficacy profile relative to other agents in this class of innate checkpoint inhibitors. AO-176 works by blocking the "don’t eat me" signal, the standard mechanism of anti-CD47 antibodies. Beyond blocking this signal, AO-176 has additional mechanisms, including directly killing tumor cells and inducing DAMPs (Damage Associated Molecular Patterns), resulting in Immunogenic Cell Death. Importantly, AO-176 binds preferentially to tumor cells, instead of to normal cells, and binds even more potently to tumors in their acidic microenvironment (low pH). Publications and presentations on AO-176 can be found at our Pubs & Posters page.

AO-176 is being evaluated in Phase 1/2 clinical trials for the treatment of patients with select solid tumors and multiple myeloma. In a Phase 1 trial in solid tumors, AO-176 demonstrated encouraging safety and evidence of anti-tumor activity when administered as a single agent. Additional information about these trials may be found at www.clinicaltrials.gov using the trial identification number NCT03834948 (solid tumors) or NCT04445701 (multiple myeloma).
