Patient selection Patients must have had histologically confirmed

Patient selection Patients must have had histologically confirmed melan oma with evidence for metastatic disease, either regional in transit metastases not amenable to complete surgical resection or distant metastases. Treating physicians were required to discuss available standard therapies including DTIC and IL 2 prior to enrolling patients. Eligibility cri teria included Wortmannin msds the presence of at least two accessible lesions amenable to excisional biopsy for correlative assays. measurable disease in addition to the lesions planned Inhibitors,Modulators,Libraries for biopsy. absence of brain metastases. no al lergies to azoles. no more than one prior immunotherapy for metastatic disease. no prior chemotherapy for any stage of disease. ECOG perform ance status of at least 1. at least 18 years of age. non pregnant and non nursing.

laboratory parameters within the following range absolute neutrophil count 1500 ul. platelet count 100,000ul. bilirubin 1. 5 mgdL. creatinine 2. 0 mgdL. Treatment plan R115777 was administered Inhibitors,Modulators,Libraries orally at a dose of 300 mg twice per day for 21 days of a 28 day cycle. Disease re staging was performed every 2 cycles. Patients could re main on treatment until unacceptable toxicity or disease progression occurred. Prior to initiation of treatment, and again during week 7, an excisional biopsy was required to be performed for biologic correlates. At the same time points, heparinized blood was obtained for analysis of effects on T cells. Evaluation of response and toxicities Disease assessment was performed using RECIST criteria every two cycles. Toxicity evaluation was performed at least once per cycle.

Dose reductions were allowed, with dose level ?1 at 200 mg BID, dose level ?2 at 100 mg BID, and Inhibitors,Modulators,Libraries dose level ?3 being permanent discontinuation. For neurologic toxicity grade 2, drug was held until reso lution to grade 1 Inhibitors,Modulators,Libraries and continued at a 1 level dose reduc tion. If the toxicity did not resolve within one week, then drug was permanently discontinued. For hematologic toxicities, if a grade 4 toxicity was observed then drug was held for up to 2 weeks. If resolution occurred to grade 1, then drug was resumed at a 1 level dose reduction. For other toxicities, if a grade 3 event was attributed to drug, then treatment was held up to 2 weeks. If toxicity resolved to grade 1, then drug was resumed at a 1 level dose re duction. If toxicity did not resolve within 2 weeks then drug was permanently discontinued.

For any grade 4 non hematologic toxicity attributed to drug, treatment was permanently discontinued. Statistical considerations A 3 stage design was used to allow for early termination if the drug appeared ineffective in this patient popula tion. A maximum of 40 patients was targeted for enroll ment, with the null hypothesis that the response rate is less than or equal to 0. 05 versus Inhibitors,Modulators,Libraries the alternative hypothesis that the response rate is greater http://www.selleckchem.com/products/FTY720.html than or equal to 0. 20.
