"There is significant unmet need for new treatment options for pancreatic cancer," said Anil Singhal, Chief Executive Officer of Trishula Therapeutics. "We look forward to building on the promising Phase 1 results to potentially advance the treatment landscape with TTX-030, which may bring benefit to patients with advanced pancreatic cancer."

The study is designed to enroll approximately 180 patients globally. Patients will be randomized equally into three study arms, receiving TTX-030 and chemotherapy (gemcitabine and nab-paclitaxel); TTX-030 and chemotherapy plus budigalimab; or chemotherapy alone. The primary endpoint of the trial is progression free survival (PFS) in a biomarker-enriched population. Secondary endpoints include PFS in the overall population, safety, objective response rate, duration of response and overall survival. Further information on the study can be found at (clinicaltrials.gov link).

Trishula will continue to develop TTX-030 in collaboration with AbbVie Inc. Per the terms of the collaboration agreement, at the conclusion of this Phase 2 study, AbbVie will have an exclusive option to license TTX-030 for further development.

About TTX-030TTX-030 is a potential first-in-class, anti-CD39 antibody designed to inhibit the activity of CD39, an enzyme that converts adenosine triphosphate (ATP) to adenosine monophosphate (AMP), the initial step in the generation of adenosine in the tumor microenvironment. TTX-030 prevents the formation of immune-suppressive extracellular adenosine and maintains high levels of immune-activating extracellular ATP, stimulating dendritic and myeloid-derived cells promoting both innate and adaptive anti-tumor immunity.

As of October 31, 2023, 17 patients (17/18, 94.4%) experienced Treatment-Emergent Adverse Events (TEAEs), with 16 patients (16/18, 88.89%) reporting drug-related Treatment-Related Adverse Events (TRAEs). Notably, all of these adverse events were of grade 1 or 2 severity, and no TRAEs of grade 3 or higher were observed. TEAEs with an incidence of over 20% included abdominal pain (4/18, 22.2%), urinary tract infection (5/18, 27.28%), nausea (6/18, 33.3%), hypokalaemia (4/18, 22.2%) and hypotension (6/18, 33.3%). 7 patients (7/18, 38.89%) experienced Serious Adverse Events (SAEs), none of which were drug-related.

Overall, MVR-T3011 IV showed great safety profile at Phase I clinical study. Currently, there are 12 evaluable patients. According to RECIST 1.1, patients with endometrial, appendiceal, and gallbladder cancer demonstrated a significant reduction in tumor burden. The maximum reduction exceeded 15% compared to the baseline.

Simultaneously, Company is conducting a series of clinical exploratory studies in China for multiple tumor types. By combining PK/PD data from Phase I clinical study in both the U.S. and China, our goal is to devise a development strategy for a registrational Phase II clinical study targeting real unmet clinical needs.

Chairwoman and CEO Dr. Grace Guoying Zhou said that, "The development of intravenously administered oncolytic virus products has long been a challenging bottleneck. Oncolytic viruses must overcome numerous hurdles, such as neutralization by antibodies or the risk of cytokine storms, in order to effectively reach tumor sites with a sufficient number of viruses to achieve anti-tumor effects. With the successful Phase I clinical study results of MVR-T3011 IV, global first clinical-stage intravenous oHSV product, our company is now fully confident and committed to expediting clinical explorations in colorectal cancer, non-small cell lung cancer, and other indications, including combination treatments with immune checkpoint inhibitor or chemotherapy. Our goal is to bring the benefits of intravenous oncolytic virotherapy to cancer patients as swiftly as possible."

About MVR-T3011

MVR-T3011, ImmVira’s proprietary 3-in-1 oHSV, is a novel genetically engineered oHSV, which aims to achieve the most favorable profile of attenuated HSV-1 with replication potency in tumor cells and highly restricted replication in normal cells. Its incorporation of two latest and well-validated exogenous genes, PD-1 antibody and IL-12, further enhances immune responses in the tumor microenvironment.
