As a result, Imugene is now recruiting for cohort 2 of each of the arms (IT and intravenous/IV) in the combination study, in addition to cohort 4 of each of the arms of the monotherapy dose escalation.Imugene MD & CEO Leslie Chong said: "We’ve now seen a very significant number of patients dosed with VAXINIA as part of the MAST study, with those patients suffering as a result of a variety of tumour types. It’s exciting that we’re getting so close to finding out the impact that this treatment is having for these patients in need."
The multicenter Phase 1 MAST trial commenced by delivering a low dose of VAXINIA to patients with metastatic or advanced solid tumours who have had at least two prior lines of standard of care treatment. The City of Hope-developed oncolytic virus has been shown to shrink colon, lung, breast, ovarian and pancreatic cancer tumours in preclinical laboratory and animal models. Overall, the study aims to recruit up to 100 patients across approximately 10 trial sites in the United States and Australia.
The clinical trial is titled "A Phase I, Dose Escalation Safety and Tolerability Study of VAXINIA (CF33- hNIS), Administered Intratumorally or Intravenously as a Monotherapy or in Combination with Pembrolizumab in Adult Patients with Metastatic or Advanced Solid Tumours (MAST)." The trial commenced in May 2022 and is anticipated to run for approximately 24 months while being funded from existing budgets and resources.
