What this trial studies

This study investigates the effects of a new medication called PF-08046032, both alone and in combination with another drug, sasanlimab, in adults with advanced cancers, including specific types of lymphomas and solid tumors. The trial is divided into three parts: the first part tests PF-08046032 alone at increasing doses, the second part evaluates the combination of PF-08046032 and sasanlimab in patients who have either progressed on prior treatments or have not yet received standard therapies, and the third part further assesses this combination in selected tumor types. The goal is to determine the safety and effectiveness of these treatments in patients with advanced malignancies.

Who should consider this trial

Good fit: Ideal candidates include adults with advanced lymphomas or solid tumors who have progressed on or after standard treatments.

Not a fit: Patients with early-stage cancers or those who have not received any prior treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for patients with advanced cancers that have not responded to existing therapies.

How similar studies have performed: Other studies have shown promise with similar approaches, particularly in targeting advanced malignancies with novel therapies.
