A Phase II Trial of Calcitriol and Naproxen in Recurrent Prostate Cancer 3rd International Symposium on Vitamin D Analogs in Cancer Prevention and Therapy Srinivas, S., Feldman, D. INT INST ANTICANCER RESEARCH. 2009: 3605–10

Abstract

Androgen-deprivation therapy is commonly used in patients with progressive prostate cancer (PCa), but can be associated with unpleasant side-effects. The objective of the study was to determine whether treatment with calcitriol and naproxen is effective in safely delaying the growth and progression of PCa in men with early recurrent disease.Patients with biochemical relapse after local therapy for prostate cancer were treated with high dose calcitriol (DN101, Novacea) (45 microg once per week) and naproxen (375 mg twice daily) for one year and followed with serum PSA levels as well as imaging studies.Twenty-one patients were enrolled in the trial. Four patients met criteria for progression, with a PSA doubling time (PSADT) that decreased while on therapy. Fourteen patients had a prolongation of PSADT compared to baseline.Combination therapy with weekly calcitriol and daily naproxen is well tolerated by most patients and prolongation of PSADT was achieved in 75% of patients.
