VANCOUVER, BC, Sept. 8, 2025 /PRNewswire/ -- USA News Group News Commentary – The FDA's unprecedented wave of Breakthrough Therapy Designations through August has accelerated development timelines for life-saving cancer treatments[1], while major pharmaceutical companies deployed several multi-billion-dollar strategic partnerhips (with one topping $11 billion) to secure next-generation immunotherapies[2]. These recent designations are creating momentum for companies advancing breakthrough oncology platforms including Oncolytics Biotech Inc. (NASDAQ: ONCY), HUTCHMED (China) Limited (NASDAQ: HCM), CG Oncology, Inc. (NASDAQ: CGON), C4 Therapeutics, Inc. (NASDAQ: CCCC), and IDEAYA Biosciences, Inc. (NASDAQ: IDYA).
Industry analysts expect the antibody-drug conjugate market to reach $50 billion by 2030[3], driven by 16 approved therapies and accelerating clinical pipelines. Immuno-oncology revenues jumped from $94 billion to $109.39 billion in 2025 alone[4], as leading institutions recognize the transformative potential of precision-targeted therapies and combination treatment approaches for previously untreatable cancers.
Oncolytics Biotech Inc. (NASDAQ: ONCY) has announced impressive clinical data in metastatic colorectal cancer that could accelerate the company's path to registration. The latest results show pelareorep achieved a median progression-free survival of 16.6 months compared to just 5.7 months with standard treatments, representing approximately 2.5 times longer disease control in KRAS mutant colorectal cancer patients.
Even more striking, overall survival reached 27.0 months versus the typical 11.2 months, representing a dramatic improvement in one of oncology's most challenging areas. This data comes from the REO 022 trial testing pelareorep with FOLFIRI and bevacizumab in second-line treatment.
"These studies validate pelareorep's mechanism of action and present a clear opportunity to accelerate the pursuit of a registration-enabled study in the underserved KRAS mutant subset of mCRC patients," said Jared Kelly, CEO of Oncolytics. "Given pelareorep's activity in this difficult-to-treat cancer and other RAS-mutated gastrointestinal ("GI") tumors, including metastatic pancreatic and anal cancers, we believe pelareorep is positioned to become the premier platform immunotherapy in the GI space."
The company plans to work with regulators to define a path toward registration in KRAS mutant colorectal cancer.
The results extend beyond survival numbers. Translational studies confirmed pelareorep actually replicates inside tumor cells while activating immune responses, including dendritic cell maturation and CD8+ T cell activation. This proves the drug's ability to transform "cold" tumors into "hot" targets responsive to immunotherapeutic treatments.
Pelareorep represents a systemically delivered oncolytic virus that reprograms the immune system against cancer. Unlike traditional chemotherapy that attacks cells indiscriminately, this immunotherapy selectively targets cancer while mobilizing the body's natural defenses.
The company is simultaneously advancing toward registration-enabling trials in first-line metastatic pancreatic ductal adenocarcinoma (mPDAC), where survival data proved equally compelling. Clinical results showed a 21.9% two-year overall survival rate compared to the 9.2% historical benchmark for standard chemotherapy protocols.
Importantly, pelareorep demonstrated a 62% objective response rate when combined with chemotherapy and checkpoint inhibitors. This matters because checkpoint inhibitors currently lack approval for pancreatic cancer, suggesting pelareorep may unlock immunotherapy effectiveness in historically resistant tumors.
Oncolytics recently provided updated safety data for pelareorep, which has been administered to over 1,200 patients across multiple studies. The most common side effects remain mild flu-like symptoms, with data showing pelareorep doesn't modify the safety profile of established chemotherapy regimens.
The company confirmed ongoing discussions with the U.S. Food and Drug Administration (FDA) to finalize pivotal study parameters for pancreatic cancer, targeting potential trial initiation activities by Q4 2025. Pelareorep holds both Fast Track and Orphan Drug designations from the FDA for pancreatic cancer, facilitating expedited review processes.
Recent leadership changes reflect an execution-focused approach. CEO Jared Kelly and Chief Business Officer Andrew Aromando both contributed to Ambrx Biopharma's US$2 billion acquisition by Johnson & Johnson. Oncolytics eliminated its At-the-Market and Equity Line financing facilities, suggesting confidence in current cash resources to reach key development milestones.
With survival benefits approaching 3× standard care in colorectal cancer and regulatory discussions advancing for pancreatic cancer trials by Q4 2025, Oncolytics appears positioned at a critical inflection point where proof-of-concept has evolved into potential registration-enabling studies. The company's dual-track approach in gastrointestinal cancers, combined with an experienced leadership team and FDA Fast Track designation, suggests pelareorep may soon transition from clinical promise to commercial reality.

In other recent industry developments and happenings in the market include:
HUTCHMED (China) Limited (NASDAQ: HCM) highlighted clinical data from multiple oncology studies at the 2025 World Conference on Lung Cancer and CSCO Annual Meeting, showcasing updated analysis from savolitinib's SACHI, SAVANNAH and Phase IIIb confirmatory studies in non-small cell lung cancer patients.
The company will present first-time clinical data of HMPL-653, a novel CSF-1R inhibitor, from a Phase I study in patients with tenosynovial giant cell tumor. Savolitinib, an oral and highly selective MET tyrosine kinase inhibitor being jointly developed with AstraZeneca, continues advancing through multiple clinical programs targeting various lung cancer indications.
According to Hutchmed's announcement, updated analysis from savolitinib's SACHI, SAVANNAH and a Phase IIIb confirmatory study in non-small cell lung cancer patients will be presented at WCLC 2025.
The comprehensive clinical program spans investigator-initiated studies of fruquintinib and surufatinib across multiple cancer types, with HUTCHMED positioning itself as an innovative commercial-stage biopharmaceutical company committed to bringing targeted therapies from in-house discovery to patients worldwide. The company has successfully marketed its first three medicines in China, with its lead compound also approved globally, including in the US, Europe and Japan.
CG Oncology, Inc. (NASDAQ: CGON) continues to demonstrate best-in-disease durability with its cretostimogene immunotherapy, reporting an additional 12 patients achieving complete response at 24 months in the BOND-003 Cohort C study. The robust 24-month complete response rate of 41.8% observed in 46 out of 110 patients with high-risk non-muscle invasive bladder cancer unresponsive to BCG treatment represents unprecedented durability in this heavily pretreated patient population. Notably, 90% of 12-month responders remained disease-free at 24 months, while 96.6% of patients were free from progression to muscle-invasive disease at 24 months.
"Based on the latest data cut, I remain very encouraged that if approved, cretostimogene will represent an important, bladder-sparing advancement in the management of high risk non-muscle invasive bladder cancer in patients who have disease that is unresponsive to BCG," said Trinity J. Bivalacqua, MD, PhD, Urologic Oncology at Penn Medicine and Co-Director, Genitourinary Cancer Service Line, Abramson Cancer Center.
