SNV4818 in Participants With Advanced Solid Tumors

Purpose

This study is testing a new medicine, SNV4818, for people with advanced cancers. The researchers want to find out if SNV4818 is safe, well-tolerated, and effective in treating solid tumors. They are investigating different doses in order to find the safest and most effective one.

Arm Groups

ArmDescriptionAssigned Intervention
Experimental
SNV4818 Monotherapy 		Participants will receive oral, daily doses of SNV4818 as a single agent as part of either dose escalation or dose expansion cohorts. The SNV4818 dose level participants receive will depend upon the study part to which they are assigned. Dose escalation participants will be assigned to small cohorts of ascending SNV4818 dose levels. Dose expansion participants will receive one of the SNV4818 dose levels recommended for further evaluation.
  • Drug: SNV4818
    SNV4818 is a tablet taken orally. Dose and frequency are dependent upon treatment arm.
Experimental
SNV4818+Fulvestrant Combination 		Participants will receive oral, daily doses of SNV4818 in combination with a standard dose of Fulvestrant as part of either dose escalation or dose expansion cohorts.. The SNV4818 dose level participants receive will depend upon the study part to which they are assigned. Dose escalation participants will be assigned to small cohorts of ascending SNV4818 dose levels. Dose expansion participants will receive one of the SNV4818 dose levels recommended for further evaluation.
  • Drug: SNV4818
    SNV4818 is a tablet taken orally. Dose and frequency are dependent upon treatment arm.
  • Drug: Fulvestrant
    Fulvestrant is administered via an intramuscular injection. It will be given at a dose of 500 mg (2-250 mg/5 mL injections)
