Integrated data from 2 randomized, double-blind, placebo-controlled, phase 3 trials of active cellular immunotherapy with Sipuleucel-T in advanced prostate cancer

Abstract: BACKGROUND: Sipuleucel-T is an investigational active cellular immunotherapy product designed to stimu­ late an immune response against prostate cancer. The safety and efficacy of sipuleucel-T was evaluated in 2 identically designed, randomized, double-blind, placebo-controlled trials (D9901 and D9902A) conducted in men with advanced prostate cancer. METHODS: A total of 225 patients were randomized in D9901 or D9902A to sipuleucel-T (n ¼ 147) or placebo (n ¼ 78), given as 3 intravenous infusions approximately 2 weeks apart. Patients were followed for survival until death or a prespecified cutoff of 36 months after randomization. RESULTS: In the integrated analysis of D9901 and D9902A, patients randomized to sipuleu­ cel-T demonstrated a 33% reduction in the risk of death (hazard ratio, 1.50; 95% confidence interval, 1.10­ 2.05; P ¼ .011; log-rank). The treatment effect remained strong after performing adjustments for imbalances in baseline prognostic factors, poststudy treatment chemotherapy use, and non–prostate cancer-related deaths. Additional support for the activity of sipuleucel-T is provided by the correlation between a measure of the product’s potency, CD54 up-regulation, and overall survival. The most common adverse events asso­ ciated with treatment were chills, pyrexia, headache, asthenia, dyspnea, vomiting, and tremor. These events were primarily grade 1 and 2, with durations of 1 to 2 days. CONCLUSIONS: The integrated results of D9901 and D9902A demonstrate a survival benefit for patients treated with sipuleucel-T compared with those treated with placebo. The generally modest toxicity profile, coupled with the survival benefit, suggests a favorable risk-benefit ratio for sipuleucel-T in patients with advanced prostate cancer. Cancer 2009;115:3670–9.

Trp-p8, a Novel Prostate-specific Gene, Is Up-Regulated in Prostate Cancer and Other Malignancies and Shares High Homology with Transient Receptor Potential Calcium Channel Proteins

Abstract: We have identified and cloned a novel gene, trp-p8, by screening a prostate-specific subtracted cDNA library. The 5694-bp cDNA has a 3312-bp open reading frame, which codes for a 1104 amino acid putative protein with seven transmembrane domains. The predicted protein revealed significant homology with the transient receptor potential (trp) family of Ca(2+) channel proteins. Northern blot analysis indicated that trp-p8 expression within normal human tissues is mostly restricted to prostate epithelial cells. In situ hybridization analysis showed that trp-p8 mRNA expression was at moderate levels in normal prostate tissue and appears to be elevated in prostate cancer. Notably, trp-p8 mRNA was also expressed in a number of nonprostatic primary tumors of breast, colon, lung, and skin origin, whereas transcripts encoding trp-p8 were hardly detected or not detected in the corresponding normal human tissues.

Peptides as ns3-serine protease inhibitors of hepatitis c virus

Abstract: The present invention discloses novel peptide compounds which have HCV protease inhibitory activity as well as methods for preparing such compounds. In another embodiment, the invention discloses pharmaceutical compositions comprising such peptides as well as methods of using them to treat disorders associated with the HCV protease.

Sipuleucel-T immune parameters correlate with survival: an analysis of the randomized phase 3 clinical trials in men with castration-resistant prostate cancer

Abstract: Purpose Sipuleucel-T, the first FDA-approved autologous cellular immunotherapy for treatment of advanced prostate cancer, is manufactured by activating peripheral blood mononuclear cells, including antigen presenting cells (APCs), with a fusion protein containing prostatic acid phosphatase. Analysis of data from three phase 3 trials was performed to immunologically characterize this therapy during the course of the three doses, and to relate the immunological responses to overall survival (OS).
