Merck Sharp & Dohme Inc. (MSD, NYSE: MRK) announced the initiation of KANDLELIT‑007, a Phase 3 clinical trial evaluating calderasib (MK‑1084), an investigational oral selective KRAS G12C inhibitor, in combination with KEYTRUDA QLEX (pembrolizumab + berahyaluronidase alfa-pmph) for the first‑line treatment of patients with KRAS G12C‑mutant, advanced or metastatic nonsquamous non‑small cell lung cancer (NSCLC).
Clinical Trial Design
| Item | Detail |
|---|---|
| Study Name | KANDLELIT‑007 (NCT07190248) |
| Phase | Phase 3 |
| Design | Randomized, unblinded open‑label, multicenter |
| Population | Newly diagnosed KRAS G12C‑mutant advanced/metastatic nonsquamous NSCLC |
| Enrollment | ~675 patients globally |
| Regimen | Calderasib (oral QD) + KEYTRUDA QLEX (SC) vs. KEYTRUDA QLEX + pemetrexed + carboplatin/cisplatin (IV) |
| Primary Endpoint | Progression‑free survival (PFS) in PD‑L1 TPS ≥ 1% patients |
| Key Secondary Endpoints | PFS in all participants, OS, ORR, DOR, safety (PD‑L1 ≥ 1% and all comers) |
Product Profile
Calderasib (MK‑1084):
- Mechanism: Potent, specific, covalent KRAS G12C inhibitor
- Administration: Oral once daily
KEYTRUDA QLEX:
- Fixed‑combination: Pembrolizumab (PD‑1 blocker) + berahyaluronidase alfa
- Mechanism: Hyaluronidase enhances dispersion for subcutaneous pembrolizumab delivery
Synergistic Rationale: KRAS G12C inhibition sensitizes tumors to PD‑1 blockade, while SC administration improves patient convenience.
Market Opportunity: KRAS G12C NSCLC
Disease Burden:
- Global Incidence: ~45,000 KRAS G12C‑mutant NSCLC cases annually (US: 13,000; China: 18,000)
- Current Standard: Chemo‑immunotherapy (ORR ≈ 30‑40%, mPFS ≈ 6 months)
- Market Size: ¥8‑10 billion China opportunity; $3‑4 billion US opportunity by 2030
Competitive Landscape:
- Sotorasib (Amgen) and adagrasib (Mirati/BMS) approved for later lines only
- No approved first‑line KRAS G12C therapy globally
Financial Implications
Investment: Merck will allocate USD 250‑300 million for KANDLELIT‑007 trial execution.
Peak Sales Potential: If successful, the combination could generate $2‑3 billion globally, with KEYTRUDA franchise benefiting from extended lifecycle.
