|Condition or disease||Intervention/treatment||Phase|
|Erectile Dysfunction, CTCAE Impotence Prostate Adenocarcinoma||Drug: Atorvastatin Drug: Pentoxifylline Dietary Supplement: Vitamin E Compound||Phase 2|
I. To estimate the proportion of patients who achieve a clinically significant improvement in erectile dysfunction (ED) when treated with a combination of atorvastatin or patient's currently prescribed statin, vitamin E, and pentoxifylline (PAVE).
I. To report the safety profile of PAVE. II. To report the rate of choosing other ED treatments after PAVE.
Patients receive atorvastatin orally (PO) once daily (QD) for up to 6 weeks in the absence of disease progression or unacceptable toxicity. Beginning week 7, patients receive atorvastatin PO QD, vitamin E PO QD, and pentoxifylline PO thrice daily (TID) for up to 12 months in the absence of disease progression or unacceptable toxicity.

Experimental: Treatment (atorvastatin, vitamin E, pentoxifylline)
Patients receive atorvastatin PO QD for up to 6 weeks in the absence of disease progression or unacceptable toxicity. Beginning week 7, patients receive atorvastatin PO QD, vitamin E PO QD, and pentoxifylline PO TID for up to 12 months in the absence of disease progression or unacceptable toxicity.
Dietary Supplement: Vitamin E Compound
- Change in International Index of Erectile Function (IIEF) scores [ Time Frame: Baseline up to 12 months ]Patients' baseline erectile dysfunction (ED) levels will be reported along with the proportion for patients who improve by at least 1 level according to the IIEF for each time point measured. The proportion will be reported along with a 95% credible interval implementing a non-informative prior of beta (0.33, 0.67). Additionally, the proportion of patients who ever improve by at least 1 level will be reported overall.
- Incidence of adverse events (AEs) [ Time Frame: Up to 12 months ]The safety profile of the pentoxifylline, atorvastatin and vitamin E (PAVE) combination will be reported for each cohort, with adverse events summarized by grade and time to onset to first grade 3 adverse event.
- Rate of choosing other ED treatments after PAVE [ Time Frame: Up to 12 months ]The number of patients who drop out of the study to start an ED prescription medication will be reported.
- Baseline patient features [ Time Frame: Baseline ]Exploratory analyses will be utilized to determine whether baseline patient features can predict response to PAVE or adverse events.
