GI-108 monotherapy for people with advanced or metastatic solid tumors
Official title: An Open-label, Multicenter, Dose Escalation and Expansion Phase 1/2 Study to Evaluate the Safety, Tolerability and Pharmacokinetics, and Anti-tumor Activity of GI-108, an Anti-CD73-IgG4 Fc-IL-2v Bispecific Fusion Protein, as a Single Agent in Patients With Advanced or Metastatic Solid Tumors
Run by GI Innovation, Inc. · NCT07172802 · Data updated 2026-11-12
We are testing GI-108 by itself to see if it is safe and can shrink tumors in people with advanced or metastatic solid tumors, including lung, head and neck, and pancreatic cancers.

Is this trial a fit for you?
✓Likely a good fit
Adults (≥18 years) with measurable advanced or metastatic solid tumors, ECOG performance status 0–1, adequate organ and marrow function, and prior therapy–related toxicities resolved to Grade ≤1 are the intended candidates.
✕Probably not a fit
Patients with active CNS metastases or carcinomatous meningitis, active hepatitis B or C, active tuberculosis, uncontrolled infections, or inadequate organ function are unlikely to benefit or be eligible.

What this trial studies
This open-label, multicenter phase 1/2 trial gives GI-108 as a single agent to adults with advanced or metastatic solid tumors. The study uses a dose-escalation phase to establish a maximum tolerated or recommended phase 2 dose, followed by dose-expansion cohorts that may be enriched for specific tumor types or characteristics. Primary assessments include safety, tolerability, pharmacokinetics and pharmacodynamics, with anti-tumor activity measured by RECIST v1.1. There is no control arm and cohort expansion decisions are made by a Safety Monitoring Committee based on emerging safety, PK, PD and efficacy data.
Why it matters
Potential benefit: If successful, GI-108 could offer a new immune-based treatment that boosts anti-tumor responses and may shrink tumors in these hard-to-treat cancers.
How similar studies have gone: Related approaches targeting CD73 or using engineered IL-2 variants have shown promising early-phase signals but are not yet proven in later-stage trials.
