Enzalutamide With Ribociclib in Treating Patients With Metastatic Castrate-Resistant, Chemotherapy Naive Prostate Cancer That Retains Retinoblastoma Expression
Stopped: Sponsor-PI decision. An analysis of the primary endpoint concluded that the addition of ribociclib to standard of care enzalutamide did not demonstrate benefit, an all active subjects were removed from the study.

Plain-language summary
This phase Ib/II trial studies the safety, side effects, best dose, and effectiveness of ribociclib when given with enzalutamide in treating patients with castrate-resistant prostate cancer that has spread from the primary site (place where it started) to other places in the body (metastatic), is chemotherapy naive, and retains retinoblastoma expression. Testosterone can cause the growth of prostate cancer cells. Hormone therapy using enzalutamide may fight prostate cancer by blocking the use of testosterone by the tumor cells. Ribociclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Enzalutamide with ribociclib may be safe, tolerable and/or effective in treating metastatic, castrate-resistant, chemotherapy naive prostate cancer that retains retinoblastoma expression.

Inclusion Criteria:
* Willing and able to provide written informed consent and Health Insurance Portability and Accountability Act (HIPAA) authorization for the release of personal health information; NOTE: HIPAA authorization may be either included in the informed consent or obtained separately; consent and HIPPA authorization must be obtained prior to any screening procedures
* Histological or cytological proof of prostate cancer
* Documented progressive metastatic (m)CRPC based on at least one of the following criteria:
* PSA progression defined as 25% increase over baseline value with an increase in the absolute value of at least 2 ng/mL that is confirmed by another PSA level with a minimum of a 1 week interval and a minimum PSA of 2 ng/mL
* Soft-tissue progression defined as an increase \>= 20% in the sum of the longest diameter (LD) of all target lesions based on the smallest sum LD since treatment started or the appearance of one or more new lesions
* Progression of bone disease (evaluable disease) or (new bone lesion\[s\]) by bone scan
* Have testosterone \< 50 ng/dL; patients must continue primary androgen deprivation with an luteinizing hormone-releasing hormone (LHRH) analogue (agonist or antagonist) if they have not undergone orchiectomy
* Eastern Cooperative Oncology Group (ECOG) performance status of 0-1
* Patients on long term (\> 6 months) anti-androgen therapy (e.g., flutamide, bicalutamide, nilutamide) will need to be off anti-androgen for 4 weeks (w…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
