"Our core programs in pancreatic and breast cancer are both progressing rapidly towards registrational studies on the back of the impressive clinical data showing the potential of pelareorep as a backbone immunotherapy," said Dr. Matt Coffey, President and Chief Executive Officer. "Data reported at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting from our BRACELET-1 randomized phase 2 trial demonstrated robust improvements in objective response rate (ORR) and progression-free survival (PFS) with a hazard ratio of 0.29 (95% CI: 0.09, 0.98). This has unlocked the potential for including PFS as a dual endpoint in our registrational trial, which could considerably reduce the time to a pivotal readout. At the same time, pelareorep was selected for inclusion in the ongoing Precision Promise pancreatic cancer platform trial. Precision Promise, created by the Pancreatic Cancer Action Network, provides us with the opportunity to reduce the time and costs needed for a potential approval, and we are honored to have been selected for participation in this novel and exclusive trial."
Second Quarter and Subsequent Highlights
Breast Cancer Program
BRACELET-1 data demonstrated a >50% improvement in progression-free survival and a nearly three-fold increase in confirmed overall response rate
An oral presentation at the ASCO (Free ASCO Whitepaper) Annual Meeting featured results from a randomized trial of pelareorep in HR+/HER2- metastatic breast cancer. As of a March 3, 2023 cut-off date, BRACELET-1 data in the paclitaxel plus pelareorep cohort showed median PFS of 9.5 months, compared to 6.3 months in the paclitaxel monotherapy cohort. This resulted in a hazard ratio of 0.29 (95% CI: 0.09, 0.98), indicating the pelareorep-paclitaxel combination reduced the risk of disease progression by 71%. Confirmed ORR in these cohorts was 37.5% for paclitaxel plus pelareorep and 13.3% for paclitaxel. Overall survival data continues to mature as several patients are still on study. With these data, the HR+/HER2- metastatic breast cancer program is now phase 3-ready, and, with two randomized phase 2 trials showing meaningful benefits to patients, the focus is now on progressing to a registrational trial evaluating pelareorep-paclitaxel compared to paclitaxel alone.
Oncolytics hosted a key opinion leader (KOL) webinar on June 5, 2023 where breast cancer experts and the management team discussed recent data from the BRACELET-1 study. A link to the replay is available by clicking here.
Pancreatic Cancer Program
Pelareorep selected for inclusion in Precision Promise Pivotal Phase 3 Platform Trial
Pelareorep has been selected for inclusion as a new investigational treatment in Precision Promise. Created by the Pancreatic Cancer Action Network (PanCAN), Precision Promise is an innovative adaptive phase 3 clinical trial designed to streamline registration pathways for promising pancreatic cancer therapies. Inclusion is expected to accelerate the registrational pathway and reduce by half the phase 3 costs compared to a traditional trial. The study is designed to evaluate pelareorep in combination with a checkpoint inhibitor and the chemotherapeutic agents gemcitabine and nab-paclitaxel in comparison to gemcitabine and nab-paclitaxel standard of care therapy. This clinical study is expected to support the approval of the pelareorep combination therapy as a treatment for first-line metastatic pancreatic ductal adenocarcinoma.
Additional Immunotherapeutic Opportunity
Preclinical pelareorep-chimeric antigen receptor (CAR) T cell therapy combination program
A poster presentation at ASCO (Free ASCO Whitepaper) showed preclinical results of pelareorep synergistically enhancing CAR T cell therapy efficacy in murine solid tumor models (link to the poster). The results suggest pelareorep could substantially expand the commercial potential of CAR T cell therapy beyond hematologic malignancies to include solid tumors, which represent the vast majority of cancer cases. Oncolytics is currently advancing preclinical research collaborations evaluating pelareorep-CAR T cell combination therapies.
Financial Highlights
As of June 30, 2023, the Company reported $24.4 million in cash, cash equivalents, and marketable securities, then successfully closed a US$15 million public offering on August 8, 2023. On a pro forma basis, including the estimated US$13.6 million in net proceeds from the public offering, the Company’s cash, cash equivalents and marketable securities would have been approximately $42.7 million.
The net loss for the second quarter of 2023 was $7.4 million, compared to a net loss of $5.1 million for the second quarter of 2022. The basic and diluted loss per share was $0.12 in the second quarter of 2023, compared to a basic and diluted loss per share of $0.09 in the second quarter of 2022.
Net cash used in operating activities for the six months ended June 30, 2023 was $16.3 million, compared to $13.2 million for the six months ended June 30, 2022. The change reflected higher net operating activities and non-cash working capital changes.
General and administrative expenses for the second quarter of 2023 were $3.5 million, compared to $2.8 million for the second quarter of 2022. The increase was primarily due to higher investor relations activities and annual general meeting of shareholders costs.
Research and development expenses for the second quarter of 2023 were $3.7 million, compared to $3.2 million for the second quarter of 2022. The increase was primarily due to higher manufacturing expenses associated with an engineering production run along with process and analytical development activities and higher personnel-related expenses. The increase was partly offset by lower BRACELET-1 study costs.
