Title
Thymosin Alpha 1, Interferon Alpha, or Both, in Combination With Dacarbazine in Patients With Malignant Melanoma
A Phase II, Multicentre, Open, Randomised, Dose Ranging Study to Investigate the Efficacy of Combination Therapy Containing Dacarbazine (DTIC) Plus Low Dose Interferon Alpha (aIFN) Plus Thymosin a1 Versus Both DTIC Plus Thymosin a1 and DTIC Plus aIFN in Patients With Advanced -Stage Metastatic Malignant Melanoma

dacarbazine thymalfasin interferon alpha-2b ...Study Participants
488The purpose of the study is to test safety and efficacy of different doses of thymosin alpha 1 (1.6 mg, 3.2 mg, and 6.4 mg) in combination with dacarbazine and with or without Interferon alpha in treating patients affected by stage IV melanoma.
Primary end-point is Tumor Response evaluated according to Response Evaluation Criteria In Solid Tumors (RECIST). Secondary end-points are Overall Survival and Progression Free Survival.
Ninety-five patients are allocated to each arm to test the hypothesis that P0 <= 0.05 vs the alternative hypothesis that P1 >= 0.15 (alpha = 5%, within-group statistical analysis beta = 95%).
Dacarbazine 800 mg/m2 IV on day 1;Interferon alpha 3MIU SC on day 11 and 18; Thymosin-alpha-1 1.6 mg SC from day 8 to 11 and from day 15 to 18 of each 28 day cycle up to 6 cycles or until progression or unacceptable toxicity develops.
Dacarbazine 800 mg/m2 IV on day 1; Interferon alpha 3MIU SC on day 11 and 18; Thymosin-alpha-1 3.2 mg SC from day 8 to 11 and from day 15 to 18 of each 28 day cycle up to 6 cycles or until progression or unacceptable toxicity develops.
Dacarbazine 800 mg/m2 IV on day 1; Interferon alpha 3MIU SC on day 11 and 18 Thymosin-alpha-1 6.4 mg SC from day 8 to 11 and from day 15 to 18 of each 28 day cycle up to 6 cycles or until progression or unacceptable toxicity develops.
Dacarbazine 800 mg/m2 IV on day 1; Thymosin-alpha-1 3.2 mg SC from day 8 to 11 and from day 15 to 18 of each 28 day cycle up to 6 cycles or until progression or unacceptable toxicity develops.

Tumor response is measured according to Response Evaluation Criteria In Solid Tumors (RECIST) computing number of Complete Response plus Partial Response
The survival time for each patient is defined as the time between randomization and death. Patients lost to follow-up or still alive at the date of last evaluation have been censored.
Progression Free Survival is defined as the time from the randomization to progression or death
