A Phase 2 Study of VS-7375 in Patients With KRAS G12D-Mutated Non-Small Cell Lung Cancer (TARGET-D 202)

June 15, 2026 updated by: Verastem, Inc.

A Phase 2, Open-label Study of VS-7375, an Oral KRAS G12D (ON/OFF) Inhibitor, in Patients With Previously Treated, Advanced KRAS G12D-Mutated Non-Small Cell Lung Cancer (TARGET-D 202)

This study will assess the safety and efficacy of VS-7375 alone and in combination with cetuximab in patients with metastatic KRAS G12D - mutated Non-Small Cell Lung Cancer

Description

Inclusion Criteria:

  • Histopathology confirmed unresectable locally advanced or metastatic NSCLC
  • Measurable disease per RECIST 1.1
  • Local testing confirmed KRAS G12D mutation (tissue required for confirmatory central testing)
  • ECOG PS=0 or 1
  • Adequate organ function
  • Received prior treatment with a platinum-based chemotherapy regimen and an immune checkpoint inhibitor in the advanced, non-resectable setting.
  • Have documented disease progression during or following their most recent prior line of therapy.

Patients with 2L/3L on stable or preferred dose:

  • Received at least 1 and no more than 2 prior systemic lines of therapy for advanced (in the unresectable locally advanced or metastatic setting) NSCLC.

Patients with 2L-4L with brain metastases:

  • Received at least 1 and no more than 3 prior systemic lines of therapy for advanced (in the unresectable locally advanced or metastatic setting) NSCLC.
  • Have asymptomatic and untreated brain metastases
  • At least 1 untreated measurable brain lesion per mRECIST v1.1 with a long axis ≥ 0.5 cm and ≤ 3 cm.

Exclusion Criteria:

  • Have any other documented co-existing common RAS mutation(s)
  • Prior anti-cancer Tx within 4 weeks or drug-specific timeline within first treatment dose, whichever shorter
  • Major surgery within 4 weeks of first treatment dose
  • Radiation therapy (RT) within 1 week of first treatment dose
  • History of drug-induced Interstitial Lung Disease
  • Receipt of prior direct RAS inhibitor
  • Untreated or symptomatic CNS metastasis
  • Receipt of strong CYP3A4 inhibitor/inducer or CYP3A4 sensitive substrates with narrow therapeutic index within 14 days or drug-specific timeline within first treatment dose, whichever is shorter
  • Receipt of PPI or H2 blocker within 5 days
  • Inability to swallow oral medication
  • Other protocol-defined inclusion/exclusion criteria may apply
