Brief Summary:
  • To evaluate the safety and tolerability of escalating doses of ERAS-601 when administered as a monotherapy and in combination with other cancer therapies in study participants with advanced or metastatic solid tumors.
  • To determine the Maximum Tolerated Dose (MTD) and/or recommended dose (RD) of ERAS-601 when administered as a monotherapy and in combination with other cancer therapies.
  • To characterize the pharmacokinetic (PK) profile of ERAS-601 when administered as a monotherapy and in combination with other cancer therapies.
  • To evaluate the antitumor activity of ERAS-601 when administered as a monotherapy and in combination with other cancer therapies.

Condition or disease Intervention/treatment Phase
Advanced or Metastatic Solid Tumors Drug: ERAS-601 Drug: Cetuximab Drug: Pembrolizumab Phase 1

Detailed Description:
This is a first-in-human, Phase 1/1b, open-label, multicenter clinical study of ERAS-601 as a monotherapy and in combination with other cancer therapies. The study will commence with dose escalation of ERAS-601 monotherapy, followed by dose escalation of ERAS-601 in combination with other cancer therapies. Once the monotherapy MTD and/or RD has been determined, then dose expansion of ERAS-601 monotherapy may commence with enrollment of study participants with advanced or metastatic solid tumors harboring specific molecular alterations. Once the combination therapy MTD and/or RD has been determined, then dose expansion of that combination may commence with enrollment of study participants with advanced or metastatic solid tumors harboring specific molecular alterations.

Arm Intervention/treatment
Experimental: Dose Escalation (Part A): ERAS-601 monotherapy
ERAS-601 monotherapy will be administered in sequential ascending doses to study participants with advanced or metastatic solid tumors until unacceptable toxicity, disease progression, or withdrawal of consent.
Drug: ERAS-601
Administered orally

Experimental: Dose Escalation (Part B): ERAS-601 monotherapy
ERAS-601 monotherapy will be administered in sequential ascending doses to study participants with advanced or metastatic solid tumors until unacceptable toxicity, disease progression, or withdrawal of consent.
Drug: ERAS-601
Administered orally

Experimental: Dose Escalation (Part C): ERAS-601 monotherapy
ERAS-601 will be administered in sequential ascending doses to study participants with advanced or metastatic solid tumors until unacceptable toxicity, disease progression or withdrawal of consent.
Drug: ERAS-601
Administered orally

Experimental: Dose Escalation and Dose Expansion (Part D): ERAS-601 in combination with cetuximab
ERAS-601 will be administered in sequential ascending doses with cetuximab to study participants with advanced metastatic solid tumors until unacceptable toxicity, disease progression or withdrawal of consent. Once the combination therapy recommended dose has been determined, this will be administered to study participants with HPV negative advanced or metastatic head and neck squamous cell carcinoma (HNSCC) or colorectal cancer (CRC).
Drug: ERAS-601

Experimental: Dose Escalation and Dose Expansion (Part E): ERAS-601 in combination with pembrolizumab
ERAS-601 will be administered in sequential ascending doses with pembrolizumab to study participants with advanced metastatic solid tumors until unacceptable toxicity, disease progression or withdrawal of consent. Once the combination therapy recommended dose has been determined, this will be administered to study participants with HPV negative advanced or metastatic head and neck squamous cell carcinoma (HNSCC) or non small cell lung cancer (NSCLC).
Drug: ERAS-601
Administered orally

Drug: Pembrolizumab
Administered via intravenous infusion
Other Name: Keytruda
