"We continue to build our case for pelareorep to be an important immunotherapy in multiple large and in-need cancer indications," said Dr. Matt Coffey, President and Chief Executive Officer. "The ESMO (Free ESMO Whitepaper) presentations show the first batch of survival data from first-line metastatic pancreatic cancer patients exceeds the historical averages recorded in control trials, aligning with the positive response data we first reported at SITC (Free SITC Whitepaper) last year. They also reveal that pelareorep can generate an immune response in heavily pre-treated metastatic colorectal cancer patients. I’m pleased to note that GOBLET has now reported consecutive indications where pelareorep-based therapy has met the success criteria for efficacy, validating our decision to explore pelareorep in gastrointestinal indications in combination with the checkpoint inhibitor atezolizumab. The compelling GOBLET results were instrumental in obtaining a US$5 million grant from PanCAN to explore pelareorep in combination with modified FOLFIRINOX (mFOLFIRINOX) with and without atezolizumab in pancreatic cancer patients."
Dr. Coffey continued, "Having already observed efficacy signals in pancreatic cancer from the combination of pelareorep and atezolizumab plus the standard of care regimen gemcitabine and nab-paclitaxel, we believe that with encouraging efficacy signals from a pelareorep and mFOLFIRINOX combination, we have the potential to become the go-to treatment option for a substantial number of pancreatic cancer patients."
Third Quarter and Subsequent Highlights
Pancreatic Cancer Program
Updated data reported at ESMO (Free ESMO Whitepaper) shows robust survival and translational data
A poster with data from the pancreatic cancer cohort of the Phase 1/2 GOBLET study was presented at the European Society for Medical Oncology (EMSO) Congress 2023 (link to the PR, link to the poster). This study cohort was designed to evaluate pelareorep in combination with atezolizumab and the chemotherapeutic agents gemcitabine and nab-paclitaxel in patients with advanced or metastatic pancreatic cancer. The efficacy results presented exceeded those from earlier studies, including a 62% objective response rate, a median progression-free survival of 7.2 months, an interim median overall survival of 10.6 months, and a 46% interim 12-month survival rate. These data also demonstrated the ability of pelareorep-based combination therapy to induce the expansion of both pre-existing and new T-cell clones from the tumor. This combination therapy has already been selected for inclusion in the Precision PromiseSM Pivotal Phase 3 Platform Trial (link to the PR).
Pancreatic Cancer Action Network (PanCAN) award and grant
Oncolytics was awarded the Therapeutic Accelerator Award, which includes a US$5 million grant from PanCAN, to initiate a Phase 1/2 randomized clinical trial of pelareorep combined with modified FOLFIRINOX, with or without the checkpoint inhibitor atezolizumab (link to the PR). We anticipate that the combination therapy that performs best will be further evaluated in a licensure-enabling study, such as the Precision PromiseSM Pivotal Phase 3 Platform Trial. The combination of pelareorep, gemcitabine, nab-paclitaxel, and atezolizumab has already been selected for inclusion in Precision Promise, with the trial expected to open in the first half of 2024.
Colorectal Cancer Data
ESMO presentation shows the third-line colorectal cancer cohort met its success criteria for efficacy
A poster presentation at ESMO (Free ESMO Whitepaper) announced interim results from the third-line metastatic colorectal cancer cohort of the Phase 1/2 GOBLET study (link to the PR, link to the poster). In a patient population that failed two prior lines of treatment, six of 15 patients recorded stable disease as their best response, and four had stable disease at week 16 or later, thereby meeting the prespecified success criteria for stage 1 of the study. The disease control rate was 40%, the median progression-free survival was 2.8 months, the median overall survival was 8.0 months, and the 12-month survival rate was 33%.
Breast Cancer Program
AWARE-1 abstract data reported at SITC (Free SITC Whitepaper) reinforces pelareorep’s ability to remodel the tumor microenvironment, poster to be available later today
Additional data from the AWARE-1 breast cancer study was reported in an abstract at the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) 38th Annual Meeting. AWARE-1 evaluated early-stage breast cancer patients in two cohorts who received pelareorep and letrozole with and without atezolizumab. The study met its primary endpoint of CelTIL score (a measurement of cellularity and tumor-infiltrating lymphocytes), with the arm that included atezolizumab showing enhanced outcomes. Further analysis of the tumor microenvironment of patient tissue samples was performed using imaging mass cytometry (IMC). The data show increased PD-L1 positive cells and an increase in cytotoxic T cells, amongst other benefits, which make the tumor microenvironment more amenable to treatment. The SITC (Free SITC Whitepaper) poster embargo lifts at 9 a.m. Pacific Time today, November 3, 2023, and the poster will be available on the Oncolytics website shortly after that.
Financial Highlights
As of September 30, 2023, the Company reported $40.0 million in cash and cash equivalents, with a projected cash runway for at least 12 months.
Net cash used in operating activities for the nine months ended September 30, 2023 was $22.3 million, compared to $17.4 million for the nine months ended September 30, 2022. The change reflected higher net operating activities.
General and administrative expenses for the third quarter of 2023 were $5.2 million, compared to $2.4 million for the third quarter of 2022. The increase was primarily due to higher investor relations activities and the portion of the public offering transaction costs allocated to general and administrative expenses.
Research and development expenses for the third quarter of 2023 were $5.8 million, compared to $3.7 million for the third quarter of 2022. The increase was primarily due to higher manufacturing expenses as we completed a scaled-up engineering production run and the associated batch testing. The increase was partly offset by lower clinical trial expenses related to clinical and safety data management.
The net loss for the third quarter of 2023 was $9.9 million, compared to a net loss of $4.4 million for the third quarter of 2022. The basic and diluted loss per share was $0.14 in the third quarter of 2023, compared to a basic and diluted loss per share of $0.08 in the third quarter of 2022.
