Details and patient eligibility

About

  • To evaluate the safety and tolerability of escalating doses of ERAS-801 in study participants with recurrent glioblastoma multiforme (GBM).
  • To determine the Maximum Tolerated Dose (MTD) and/or Recommended Dose (RD) of ERAS-801.
  • To evaluate the antitumor activity of ERAS-801.
  • To evaluate the PK profile of ERAS-801.

Full description

This is a Phase 1, open-label, multicenter clinical study evaluating ERAS-801 as a monotherapy. The study will initially commence with dose escalation of ERAS-801 in study participants with recurrent GBM. Once the MTD and/or RD has been determined from dose escalation, then dose expansion of ERAS-801 may commence in study participants with recurrent GBM harboring alterations in epidermal growth factor receptor (EGFR).
