What this trial studies

This clinical trial aims to assess the safety, tolerability, pharmacokinetics, and therapeutic activity of GI-101/GI-101A, both as a standalone treatment and in combination with pembrolizumab, lenvatinib, or local radiotherapy, for patients with advanced or metastatic solid tumors. The study is structured into six parts, including dose-escalation and expansion cohorts for both GI-101 and GI-101A, allowing for a comprehensive evaluation of these therapies. Participants will be monitored for anti-tumor effects and any adverse reactions throughout the trial.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older with measurable advanced solid tumors and adequate organ function.

Not a fit: Patients with active CNS metastases, second malignancies, or uncontrolled infections may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for patients with advanced solid tumors, potentially improving their outcomes.

How similar studies have performed: Other studies have shown promise with similar immunotherapy approaches, indicating potential for success in this novel combination.
