FORTIFY – PLN-101095 Phase 1a/1b Indication Expansion Trial
PLN-101095 is currently being evaluated in a Phase 1a/1b open-label, dose-escalation and indication expansion trial (NCT06270706) to evaluate the safety, tolerability, pharmacokinetics, and preliminary evidence of antitumor activity of PLN-101095 when administered orally in combination with pembrolizumab, in patients with immune checkpoint inhibitor (ICI)-refractory advanced or metastatic solid tumors. Pliant is currently enrolling patients in the Phase 1b trial portion of FORTIFY consisting of three cohorts of patients with non-small cell lung cancer (NSCLC), tumors with high tumor mutational burden or clear cell renal cell carcinoma. Patients will be treated for 14 days with PLN-101095 dosed at 1,000 mg twice daily as monotherapy, after which pembrolizumab will be added as combination therapy.
