Durable clinical benefits induced by IMV’s T cell therapy in combination with Merck’s Keytruda in subjects with PD-L1 Positive r / r DLBCL presented at ASH Annual Meeting


DARTMOUTH, Nova Scotia – (Commercial wire(NASDAQ: IMV; TSX: IMV) (“IMV” or the “Company”), a clinical-stage bio-pharmaceutical company that is pioneering a new class of cancer immunotherapies and vaccines against infectious diseases, today announces that lasting clinical benefits are induced By combining treatment of IMV’s t cell therapy with Merck’s Keytruda® (Pembrolizumab) in subjects with PD-L1 positive recurrent / refractory diffuse large B cell lymphoma (R / R DBLCL) have been presented at the American Society of Hematology (Ash) annual meeting.

“Compared to currently approved therapies, this combination has demonstrated a promising duration of response with limited adverse events in this difficult-to-treat patient population,” said Drs. . The improved clinical response in this subset of patients with PD-L1 expression is an exciting scientific finding. .1 And is more likely caused by the complementary mechanisms of action of the two immunotherapies. ”

“These are exciting early data and the potential synergistic action of the two immunotherapists paves the way for a new treatment paradigm with combination therapies,” said Dr. Joanne Schindler, Chief Medical Officer at IMV. “We will also evaluate the combination therapy with Merck in other solid tumor indications and we look forward to exploring the potential of what we have seen in the SPiReL study. ”

In his presentation at the annual ASH conference, Dr. Neil Berinstein describes the results of the SPiReL study:

  • In the PD-L1 + population (n = 7), subjects

    • Have a higher median progression free survival (PFS) of 230 days, compared with the PD-L1 negative subjects (70 days) with a p-value of 0.007, suggested for a strong predictive biomarker for this treatment combination.

    • Demonstrated an objective response in six subjects, including three subjects who had completed one year of study treatment,

    • Demonstrated an ORR and a DCR at 85.7%.

  • Peripheral blood was assessed for Survivin-specific ELISpot responses in 15 subjects with available samples. All 3 subjects with a CR and 3 of 4 subjects with PR had positive ELISpot responses while only 1 subject with SD and 1 subject with PD demonstrated Survivin-specific ELISpot response, suggested of an association between the clinical responses with the mechanism of action of DPXs -Survivac.

  • Treatment is well tolerated. The majority of treatment-related adverse events are grade 1 and 2 severity. A majority of these are injection site reactions associated with the subcutaneous administration of DPX-Survivac.

The poster presentation of dr. Berinstein is available under the section for Scientific Publications & Posters on the IMV website and is also available on the ASH meeting platform.

Biomarkers related to clinical response were also discussed at a poster presentation at the Society for Immunotherapy of Cancer (CITC) 35th Anniversary Annual Meeting, and during a webcast hosted by IMV on 12 November 2020.

About DPX-Survivac

DPX-Survivac is the main candidate in IMV’s new class of immunotherapy that generates targeted and sustained capabilities in vivo. Treatments with DPX-Survivac T cell therapy have shown a favorable safety profile in all clinical studies.

IMV’s T cell therapy, DPX-Survivac, consists of Survivin-based peptides formulated in IMV’s proprietary delivery platform (DPX). IMV’s lead compound is designed to generate a sustained cytotoxic T cell response against cancer cells that present Survivin peptides on their surface.

Survivin, recognized by the National Cancer Institute (NCI) as a promising tumor-associated antigen, is widely over-expressed in most cancer types, and plays an essential role in antagonizing cell death, supporting tumor-associated angiogenesis and promoting resistance to chemoth. IMV has identified more than 20 cancer indications in which the DPX-Survivac can be targeted.

DPX-Survivac has received fast track designation from the US. It. Food and Drug Administration (FDA) as maintenance therapy in advanced ovarian cancer, as well as orphan drug designation status of the US. It. FDA and the European Medicines Agency (EMA) in Ovarian Cancer.

About the SPiReL study

“SPiReL” is a phase 2 Non-randomized, open label, efficacy and safety study of a new immunotherapy combination with DPX-Survivac and Pembrolizumab. Intermittent low dose cyclophosphamide is given as an immune modulator. Subjects with R / R incurable DLCL and Survivin expression are eligible for participation. The primary outcome is to document the objective response rate using modified Cheson criteria for the combination treatment. Secondary objectives include safety, duration of response and time to further treatment. Exploratory endpoints include T cell response, tumor immune cell infiltration and biomarker analysis. To date, 24 subjects have been enrolled.
