A phase 1/2 study of rigosertib in patients with myelodysplastic syndromes (MDS) and MDS progressed to acute myeloid leukemia.

This Phase 1/2, dose-escalating study of rigosertib enrolled 22 patients with higher-risk myelodysplastic syndromes (MDS) (n=9) and acute myeloid leukemia (AML; n=13) who had relapsed or were refractory to standard therapy and for whom no second-line therapies were approved. Patients received 3- to 7-day continuous intravenous infusions of rigosertib, an inhibitor of Ras-effector pathways that interacts with the Ras-binding domains, common to several signaling proteins including Raf and PI3 kinase. Rigosertib was administered at doses of 650-1700mg/m/day in 14-day cycles.

The Incidence and Health Care Resource Burden of the Myelodysplastic Syndromes in Patients in Whom First-Line Hypomethylating Agents Fail.

Background: Although hypomethylating agents (HMAs) are effective and approved therapies for patients with myelodysplastic syndromes (MDS), many patients do not benefit from treatment, and nearly all ultimately stop responding to HMAs. The incidence and cost burden of HMA failure are unknown yet needed to appreciate the magnitude and significance of such failure.

Methods: We analyzed a de-identified dataset of over 5 million individuals with private health insurance in the U.

Cost-effectiveness of treatments for high-risk myelodysplastic syndromes after failure of first-line hypomethylating agent therapy.

Purpose: To evaluate optimal salvage therapy in high-risk myelodysplastic syndromes patients who have failed a first-line hypomethylating agent (HMA) therapy, given that treatment choice is challenging.

Methods: Using published literature and expert opinion, we developed a Markov model to evaluate the cost-effectiveness of current treatments for patients who failed first-line HMA therapy. The model predicted costs, life years, quality-adjusted life years and incremental cost-effectiveness ratios.

Multinational, double-blind, phase III study of prednisone and either satraplatin or placebo in patients with castrate-refractory prostate cancer progressing after prior chemotherapy: the SPARC trial.

Purpose: This multinational, double-blind, randomized, placebo-controlled, phase III trial assessed the efficacy and tolerability of the oral platinum analog satraplatin in patients with metastatic castrate-refractory prostate cancer (CRPC) experiencing progression after one prior chemotherapy regimen.

Patients And Methods: Nine hundred fifty patients were randomly assigned (2:1) to receive oral satraplatin (n = 635) 80 mg/m(2) on days 1 to 5 of a 35-day cycle and prednisone 5 mg twice daily or placebo (n = 315) and prednisone 5 mg twice daily. Primary end points were progression-free survival and overall survival (OS).

Satraplatin, an oral platinum, administered on a five-day every-five-week schedule: a pharmacokinetic and food effect study.

Purpose: The study aimed to assess the pharmacokinetic behavior of satraplatin under fasted and fed conditions, and its safety and preliminary antitumor activity in adults with advanced solid tumors.

Experimental Design: Satraplatin was administered orally at 80 mg/m(2) once daily with prophylactic antiemetics for 5 consecutive days every 5 weeks. Patients were randomized to receive day 1 and day 5 doses of satraplatin in either the fed or fasted state, the order being reversed for cycle 2.
