Randomized Controlled Trial Comparative Study Clinical Trial
Phase I/II randomized trial evaluating the safety and clinical effects of repifermin administered to reduce mucositis in patients undergoing autologous hematopoietic stem cell transplantation.
To evaluate the safety of repifermin (keratinocyte growth factor-2) administered before and after autologous hematopoietic stem cell transplantation (auto-HSCT). A preliminary analysis of the ability of keratinocyte growth factor-2 to prevent mucositis was also done. ⋯ Repifermin was well tolerated. Repifermin given before and after auto-HSCT seems to be active in reducing mucositis, but a larger trial will be necessary to determine the efficacy of repifermin with this dose schedule.

Randomized Controlled Trial Multicenter Study Clinical Trial
Results of a multicenter randomized phase II trial of thalidomide and prednisone maintenance therapy for multiple myeloma after autologous stem cell transplant.
We report a multicenter, randomized phase II trial conducted to assess the tolerability of combined thalidomide and prednisone maintenance in multiple myeloma. Eligibility required administration of melphalan (200 mg/m2) with blood stem cell support within 1 year of treatment onset and initiation of maintenance within 60 to 100 days after stem cell infusion. All patients received 50 mg of prednisone by mouth on alternate days and thalidomide at a starting dose of either 200 or 400 mg daily by mouth. ⋯ Eighty-eight percent of all patients dose-reduced thalidomide and 72% of all patients dose-reduced prednisone within 2 years of beginning maintenance. The median progression-free survival post-transplant is 32.3 months, or 42.2 months from diagnosis. Only the 200 mg of thalidomide arm of this trial met our definition of a tolerable maintenance therapy, defined as no dose reductions or discontinuation due to toxicity in at least 65% of patients for a minimum of 6 months, thus establishing a dosing schedule for phase III trials.
