Summary

  • To evaluate the safety and tolerability of escalating doses of ERAS-007 in combination with other cancer therapies in study participants with advanced GI malignancies.
    • To determine the Maximum Tolerated Dose (MTD) and/or Recommended Dose (RD) of ERAS-007 administered in combination with other cancer therapies.
    • To evaluate the antitumor activity of ERAS-007 in combination with other cancer therapies.
    • To evaluate the PK profiles of ERAS-007 and other cancer therapies when administered in combination.

Description

This is a Phase 1b/2, open-label, multicenter clinical study evaluating ERAS-007 in combination with other cancer therapies in study participants with GI malignancies. This study will serve as a platform study, allowing for evaluation of safety/tolerability and efficacy of ERAS-007 in combination with other cancer therapies. The study will initially commence with dose escalation of ERAS-007 administered in combination with encorafenib and cetuximab in study participants with metastatic colorectal cancer (CRC) harboring B-Raf proto-oncogene, serine/threonine kinase (BRAF) V600E mutation; and dose escalation of ERAS-007 administered in combination with palbociclib in study participants with metastatic CRC harboring Kirsten rat sarcoma (KRAS) or neuroblastoma rat sarcoma (NRAS) mutations. Dose expansion will follow and will test ERAS-007 administered at the RD identified from each dose escalation arm in study participants with metastatic CRC.

Inclusion Criteria

Age 18 years

Palliative radiation 7 days prior to first dose of study drug
Symptomatic brain metastasis or leptomeningeal disease
Gastrointestinal conditions that may affect absorption of oral medications
Active infection requiring systemic therapy, or history of HIV infection, hepatitis B virus, or hepatitis C virus
History of chronic inflammatory bowel disease or Crohn's disease requiring medical intervention (immunomodulatory or immunosuppressive medications or surgery) 12 months prior to first study drug dose
Active, clinically significant interstitial lung disease or pneumonitis
Impaired cardiovascular function or clinically significant cardiovascular disease
History of thromboembolic or cerebrovascular events 6 months prior to first dose
Major surgery within 28 days of enrollment, or anticipation of major surgery during study treatment
Known intolerance or contraindication to encorafenib, cetuximab, or palbociclib
Pregnant or breastfeeding women
Any evidence of severe or uncontrolled systemic disease or evidence of any other significant clinical disorder or laboratory finding that renders the patient inappropriate to participate in the study
