A Dose Escalation/Expansion Study of ERAS-601 in Patients With Advanced or Metastatic Solid Tumors

Phase 1
Active, not recruiting
Conditions
Advanced or Metastatic Solid Tumors
Interventions
Registration Number
NCT04670679
Lead Sponsor
Erasca, Inc.
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.

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.
