Dr. Iglesias served as Chief Medical Officer at Senti Biosciences, Biothera Pharmaceuticals, Bionomics Ltd., Abraxis Bioscience Inc. and as Vice President, Clinical Development at Celgene.

Operational Expansion in the USA

IMV has now established a U.S. subsidiary and an office in Cambridge, Massachusetts, a world-leading biotech research hub with a large geographical concentration of biotech and pharmaceutical companies, world-renowned universities, research centers, and a highly skilled talent pool.

This new corporate office will serve as a springboard to accelerate future business development and other initiatives.

Clinical Programs with Maveropepimut-S (MVP-S, Formerly Named DPX-Survivac)

Phase 2B Study in Relapsed/Refractory DLBCL ("r/r DLBCL")

In the previous Phase 2 clinical study (SPiReL), MVP-S in combination with Merck’s KEYTRUDA and intermittent low dose cyclophosphamide (CPA) showed promising data with 50% Overall Response Rate (ORR) and 78.6% Disease Control Rate (DCR) in evaluable patients. Also, PD-L1 expression has been identified as a potential predictive biomarker of response, as PD-L1+ patients demonstrated 85.7% ORR and 85.7% DCR. Most commonly reported events are Grade 1 and 2 injection site reactions, 20.8% subjects reported Grade 3 or above adverse events.

The Company announced in April that it entered into an agreement with Merck (NYSE: MRK) to initiate a Phase 2B clinical trial to evaluate its lead compound, MVP-S, in combination with KEYTRUDA^® (pembrolizumab), Merck’s anti-PD-1 therapy, in a Phase 2B study r/r DLBCL.

The trial was initiated in June 2021, and the first sites have since been activated. PD-L1 will be assessed for every potential patient considered for enrollment.

Phase 2 DeCidE1 Study in Advanced, Recurrent Ovarian Cancer

IMV has recently completed the DeCidE1 clinical trial evaluating MVP-S in association with CPA in patients with advanced recurrent ovarian cancer. The final patient completed the study after more than 2 years of clinical benefit with MVP-S. In this study, many subjects have been through several lines of prior treatment and 57.9% patients were platinum resistant. Overall, the treatment was well tolerated with most adverse events being injection site reactions. At the 2-year cut-off, the overall survival rate in this cohort was 44.9% with a median overall survival of 19.9 months, results that support further clinical evaluation of this treatment.

Translational analyses from this trial confirm generation of tumor-antigen directed T cells by MVP-S. The details of these translational analyses have been submitted for presentation at upcoming scientific meetings. These data will also inform the discussion and design of a Phase 2B clinical study to be submitted to the FDA.

Recent Financing Strengthens IMV’s Financial Position

Public Offering

On July 20, 2021, IMV announced the closing of a public offering of 14,285,714 units at a price to the public of $1.75 per Unit, for aggregate gross proceeds to the Corporation of approximately $25 million (Estimated net proceeds are $23 million). Each unit is comprised of one common share and three-quarters of one common share purchase warrant. Each Warrant entitles the holder thereof to purchase one common share at a price of $2.10 per common share, subject to adjustment in certain events, for five years until July 20, 2026. If the warrants are fully exercised, they can represent approximately $22.5M of additional gross proceeds.

Overview of Second Quarter 2021 Financial Results

On June 30, 2021, the Company had cash and cash equivalents of $22.8 million and working capital of $24.6 million, compared with $36.3 million and $35.6 million, respectively at December 31, 2020. Subsequent to June 30, 2021, the Company completed the above-mentioned public offering of 14,285,714 units at $1.75 per unit for gross process of $25 million (estimated net proceeds of $23 million) resulting in pro-forma cash and cash equivalents of $45.8 million as of June 30, 2021. Based on its current plan, IMV expects its current cash position will be sufficient to fund operations for more than 12 months.

Research and development expenses were $5.2 million for the three months ended June 30, 2021, compared with $3.8 million for the three months ended June 30, 2020. This increase of $1.4 million was mainly due to startup costs for the Phase 2B trial in DLBCL, the timing of manufacturing activities for MVP-S and DPX-SurMAGE, and an increase in headcount. These increases were partly offset by a decrease in costs for the pre-clinical development of DPX-COVID-19 and costs for the ongoing basket trial of MVP-S in several cancer indications.

General and administrative expenses were $3.4 million for the three months ended June 30, 2021, compared with $2.2 million for the three months ended June 30, 2020. This increase of $1.2 million was mainly attributable an increase in the Company’s Directors and Officers insurance premium as a result of rate increases in mid-2020, an increase in headcount and an increase in recruiting fees for new executives and board members.

Government assistance totaled $1.2 million for the three months ended June 30, 2021, compared with $1 million in Q2 2020. This increase in mainly driven by the revaluation of the Nova Scotia loan upon receipt of the 2-year deferral of repayments partly offset by a decrease in various government grants for the development of DPX-COVID-19, consistent with the decrease in development expenses described above.

The net loss and comprehensive loss of $7.4 million ($0.11 per share) for the three months ended June 30, 2021, was $2.6 million higher than the net loss and comprehensive loss of $4.8 million ($0.08 per share) for the three months ended June 30, 2020.

For the six-month period ended June 30, 2021, the net loss and comprehensive loss of $14.3 million ($0.21 per share) was $2.3 million higher than the net loss and comprehensive loss of $12.0 million ($0.24 per share) for the six-month period ended June 30, 2020. The higher net loss is primarily the result of a $1.1 million increase in R&D expenses and a $2 million increase in general and administrative expenses partly compensated by a $1 million increase in government assistance mainly towards COVID-19 vaccine development as well as the revaluation of the loan with the province of Nova Scotia upon receipt of the above-mentioned amendment.

As of August 10, 2021, the number of issued and outstanding common shares was 82,142,629 and a total of 15,705,452 stock options, warrants and deferred share units were outstanding.

About IMV

IMV Inc. is a clinical stage biopharmaceutical company dedicated to making immunotherapy more effective, more broadly applicable, and more widely available to people facing hard-to-treat cancer and other unmet medical needs. IMV is pioneering a novel class of cancer immunotherapies based on the Company’s proprietary delivery platform (DPX). This patented technology leverages a differentiated mechanism of action that generates a targeted and durable immune activation with limited side effects. IMV’s lead candidate, maveropepimut-S (formerly named DPX-Survivac), is a T cell-activating immunotherapy that combines the utility of the platform with a novel cancer target: survivin. IMV is currently assessing maveropepimut-S in breast and advanced ovarian cancer, as well as a combination therapy in multiple clinical studies with Merck. IMV is also developing another DPX-based immunotherapy: DPX-SurMAGE, a dual targeted immunotherapy to be evaluated in subjects with bladder cancer later this year.
