Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a Phase 1 and Phase 2 study to determine the safety profile, RDR and/or MTD, DLT, PK/PD, and preliminary antitumor activity of INV-9956 in adult patients with advanced mCRPC.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a Phase 1 and Phase 2 study to determine the safety profile, RDR and/or MTD, DLT, PK/PD, and preliminary antitumor activity of INV-9956 in adult patients with advanced mCRPC.

The entire study consists of two parts: Phase 1 for dose escalation and Phase 2 for dose expansion. The screening period for all phases is up to 28 days, and one treatment cycle is 28 days.

The investigational drug will be co-administered with once daily (QD) dexamethasone 1.5 mg and fludrocortisone acetate 0.1 mg as corticosteroid replacement therapy.

2. History of pituitary or adrenal dysfunction.
3. Poorly controlled diabetes mellitus.
4. Clinically significant abnormality in serum potassium and sodium.
5. Have a serious nonmalignant disease (eg, hydronephrosis, liver failure, or other conditions) that could compromise protocol objectives in the opinion of the Investigator and/or the Sponsor.
