Portage Biotech Highlights First Patient Dosed in IMP-MEL Study of PORT-2 for the Treatment of Melanoma and Non-Small Cell Lung Cancer (NSCLC)
- Novel iNKT agonist leads to a broad reprogramming of the innate and adaptive immune system to target cancer
- PORT-2 has the potential to re-sensitize checkpoint-resistant tumors to treatment with PD-1 antibodies
Preclinical data for PORT-2 demonstrated good tolerability and a strong cancer-specific B- and T-cell response. It also showed a robust innate and adaptive immune response and an increase in expression of PD-L1 on cancer cells. Combining PORT-2 with checkpoint inhibitors led to increased immune activation and PD-L1 expression, suggesting rationale for enhanced activity of the combination treatment.
“PORT-2 offers a novel, targeted approach to address a variety of today’s most common cancers, many of which are often elusive or resistant to treatment. Preclinical data show that our iNKT agonist can stimulate a broad response from both the innate and adaptive immune systems, helping the body recognize and attack these cancers,” said Dr.
The IMP-MEL study is expected to enroll 100 patients at
“Checkpoint inhibitor therapies have enormous opportunity in the treatment of solid tumors, but unfortunately, many cancers develop a resistance to these therapies leaving many patients without adequate treatment options,” said
The IMP-MEL study is part of a comprehensive clinical development plan to evaluate Portage’s iNKT agonist therapies, PORT-2 and PORT-3. PORT-3, which is a nanoparticle co-formulation of IMM60 and a NY-ESO-1 peptide antigen, is also currently being evaluated in a Phase 1 clinical trial initiated in
