Summary
This trial is testing a new drug called PF-06821497 to see if it can help adults with certain hard-to-treat cancers. The drug is taken by mouth and is being studied alone or with other treatments to check its safety and effectiveness in stopping cancer growth.
Who is the study for?
This trial is for adults with advanced lung cancer, prostate cancer resistant to hormone therapy, or follicular lymphoma. Participants must have a confirmed diagnosis, adequate organ function, and an ECOG Performance Status of 0 or 1 (fully active or restricted in physically strenuous activity but ambulatory). They should not be using certain foods/drugs that affect the study medication.
What is being tested?
PF-06821497 is being tested in this Phase 1 trial to find out the best dose and its safety for treating relapsed/refractory small cell lung cancer (SCLC), castration-resistant prostate cancer (CRPC), and follicular lymphoma (FL). The study will gradually increase doses for new patients based on how earlier participants respond.
What are the potential side effects?
Potential side effects of PF-06821497 are not specified here but may include typical reactions seen with cancer treatments such as nausea, fatigue, blood count changes leading to increased infection risk, liver function alterations, and possible allergic reactions.

Research Highlights
Information in this section is not a recommendation. We encourage patients to speak with their healthcare team when evaluating any treatment decision.Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
Common treatments for prostate cancer include androgen deprivation therapy (ADT), which reduces androgen levels to prevent cancer growth, and androgen receptor inhibitors like enzalutamide and abiraterone, which block androgen signaling. Additionally, poly(ADP-ribose) polymerase (PARP) inhibitors target DNA repair mechanisms in cancer cells with homologous recombination repair (HRR) deficiencies.
Understanding these mechanisms is crucial for patients as it helps tailor treatments based on the molecular characteristics of their cancer, potentially improving efficacy and reducing side effects. Novel agents like PF-06821497, which may target specific molecular pathways, represent a promising area of research, offering hope for more effective and personalized therapies.
