Portage Biotech Resumes Enrollment in Final Cohort of Dose Escalation for Port-6 in ADPORT-601 Trial
DOVER, Del., March 12, 2025 (GLOBE NEWSWIRE) -- Portage Biotech Inc. ("Portage" or the "Company") (NASDAQ:PRTG), a clinical-stage immuno-oncology company with a portfolio of innovative therapeutics, today announced the resumption of patient enrollment in the fourth and final cohort of the dose escalation stage for PORT-6, a highly selective A2A antagonist, within its ADPORT-601 Phase 1b clinical trial. Portage had previously paused this trial due to funding concerns; this resumption of the trial underscores the encouraging findings observed in earlier cohorts. After the completion of the PORT-6 arm of the ADPORT-601 study, Portage will evaluate the continuation of the study into its PORT-7 (potent and selective A2B antagonist) and combination arms, on a segment-by-segment basis.
Advancing to this final dose escalation reaffirms Portage's confidence in the safety and therapeutic potential of PORT-6, bringing the Company closer to identifying an optimal dose range for further clinical development.
"Our review of the preliminary data reinforces our confidence in PORT-6 and supports the decision to complete dose escalation," said Alexander Pickett, Chief Executive Officer of Portage Biotech. "We remain encouraged by the trial's progress and potential and look forward to sharing further clinical updates later this year."
Combining PORT-6 and PORT-7 for a More Comprehensive Immunotherapy Approach
In parallel, Portage is making final preparations for PORT-7, a potent and selective A2B antagonist, before dose escalation can commence in the same trial. The planned co-administration of PORT-6 and PORT-7 in ADPORT-601 will mark the first time two highly selective A2A and A2B antagonists are combined in patients, aiming to achieve a complete blockade of adenosine-induced immunosuppression in the tumor microenvironment. This innovative approach is designed to fully neutralize adenosine-mediated immune suppression, enhance anti-tumor responses, and broaden the impact of immunotherapy in solid tumors.
