Calderasib plus subcutaneous pembrolizumab for KRAS G12C non-small cell lung cancer

A Phase 3, Randomized, Open-label, Multicenter Clinical Study to Evaluate the Safety and Efficacy of MK-1084 in Combination With Subcutaneous Pembrolizumab and Berahyaluronidase Alfa (MK-3475A) Versus MK-3475A in Combination With Pemetrexed/Platinum (Carboplatin or Cisplatin) Chemotherapy as First-line Treatment of Participants With KRAS G12C-Mutant, Advanced or Metastatic Nonsquamous NSCLC (KANDLELIT-007)

PHASE3 · Merck Sharp & Dohme LLC · NCT07190248

This trial will test whether adding the KRAS G12C drug calderasib to subcutaneous pembrolizumab helps people with advanced nonsquamous non‑small cell lung cancer live longer without the cancer growing compared with pembrolizumab plus chemotherapy.

What this trial studies

This is a phase 3, randomized study comparing calderasib combined with subcutaneous pembrolizumab versus subcutaneous pembrolizumab with standard platinum‑based chemotherapy (pemetrexed plus cisplatin or carboplatin) in patients with advanced nonsquamous NSCLC. Calderasib is a targeted therapy directed at the KRAS G12C mutation, and the pembrolizumab is given in a subcutaneous formulation with hyaluronidase. The main goal is to determine whether the calderasib combination prolongs the time patients live without disease progression compared with the chemotherapy arm. The trial is conducted at multiple U.S. centers and is sponsored by Merck Sharp & Dohme LLC.

Who should consider this trial

Good fit: Adults with unresectable nonsquamous NSCLC (Stage IIIB/IIIC or Stage IV) whose tumors harbor a KRAS G12C mutation and who meet other health and treatment‑history criteria are the intended participants.

Not a fit: Patients with small cell lung cancer or mixed tumors containing small cell elements, active inflammatory bowel disease requiring immunosuppression, uncontrolled cardiovascular or gastrointestinal conditions, or other disqualifying prior treatments are unlikely to be eligible or to benefit from this trial.

Why it matters

Potential benefit: If successful, the combination could extend progression‑free survival for patients with KRAS G12C NSCLC and might reduce or delay the need for conventional chemotherapy.

How similar studies have performed: Earlier-phase studies of KRAS G12C inhibitors and of PD‑1 immunotherapy have shown clinical activity, and combinations are promising but not yet proven in large randomized trials, so this phase 3 trial addresses that open question.
