Description of intervention(s) / exposure
Treatment: Drugs - ERAS-601
Treatment: Drugs - Cetuximab
Treatment: Drugs - Pembrolizumab

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.

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.

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.

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).

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).

Summary
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
