• To evaluate antitumor activity of ERAS-007 in various solid tumors.
• To evaluate the safety and tolerability of ERAS-007 (BID-QW) and ERAS-601 (twice daily for three weeks on and 1 week off (BID 3/1)) when administered in combination.
• To determine the Maximum Tolerated Dose (MTD) and/or Recommended Dose (RD) of ERAS-007 administered in combination with ERAS-601.
• To characterize the pharmacokinetic (PK) profile of ERAS-007 and ERAS-601 when administered in combination.

Detailed Description

This is a Phase 1b/2, open-label, multicenter clinical study of ERAS-007 monotherapy (QW or BID-QW) administered either QW or BID-QWand ERAS-007 (BID-QW) in combination with ERAS-601 (BID 3/1). The monotherapy RD on a weekly schedule has been determined to be 250 mg QW in a previous study. The dose escalation phases of this study will test ERAS-007 monotherapy administered BID-QW as a monotherapy or in combination with ERAS-601 in participants with any solid tumor. The monotherapy RD on a weekly schedule has been determined to be 250 mg QW in a previous study. In parallel, the dose expansion phase of this study will test ERAS-007 monotherapy administered at the RD of 250 mg QW in participants with advanced or metastatic solid tumors harboring specific molecular alterations. Once sufficient safety and PK data are available from the BID-QW dose escalation phase, the Sponsor will then determine the optimal dose and schedule of ERAS-007 administered as a monotherapy.

Eligibility Criteria

Inclusion Criteria

• Age ≥ 18 years.
• Willing and able to give written informed consent.
• Have histologically or cytologically confirmed advanced or metastatic solid tumor with a relevant molecular alteration (as applicable).
• There is no available standard systemic therapy available for the patient's tumor histology and/or molecular biomarker profile; or standard therapy is intolerable, not effective, or not accessible; or patient has refused standard therapy.
• Recovered from all toxicities associated with prior treatment to acceptable baseline status.
• Have ECOG performance status of 0 or 1 with an anticipated life expectancy of > 12 weeks.
• Willing to comply with all protocol-required visits, assessments, and procedures.
• Able to swallow oral medication.

Exclusion Criteria

• Currently receiving another study therapy or has participated in a study of an investigational agent and received study therapy within 4 weeks of the first dose of ERAS-007.
• Received previous treatment with an ERK inhibitor.
