Oneof the authors of that paper was Austin Bradford Hill, who is credited as having conceived the modern RCT. Both vemurafenib (in braf V600 mutant melanoma) and ipilimumab showed superior OS compared with dtic in the two separate trials. Most responses were evident at the first radiologic assessment at 6 weeks; however, some patients did not respond until after receiving therapy for more than 6 months. The dosing regimen of 1 mg/kg of IV nivolumab when combined with ipilimumab will remain unchanged until after therapy with ipilimumab is complete when the regimen will change to a 240 mg dose every 2 weeks until disease progression or intolerable toxicity. After randomization, the two (or more) groups of subjects are followed in exactly the same way and the only differences between them is the care they receive. 46 In practice, clinical investigators in RCTs often find it difficult to maintain impartiality. Law MR, Kawasumi Y, Morgan SG (2011). Given the rapid development of new agents and combinations, patients and their physicians are encouraged to consider treatment in a clinical trial for initial treatment and at the time of progression. Designing randomised trials in health, education and the social sciences: an introduction. "Allocation concealment in randomised trials: defending against deciphering" (PDF). "A Mock Randomized Controlled Trial With Audience Response Technology for Teaching and Learning Epidemiology". Evidence (vemurafenib Previously untreated patients: The approval of vemurafenib was supported by an international, multicenter trial ( brim-3 NCT01006980) that screened 2,107 patients with previously untreated stage iiic or IV melanoma for the braf V600 mutation and identified 675 patients via the Cobas 4800 braf. The primary endpoint was survival. Twenty patients had non- braf V600E mutations: 19 with braf V600K and 1 with braf V600D. Median RFS had not been reached in the combination arm (95 CI,.5not reached) and was.6 months (95 CI,.722.1) in the placebo group. A multicenter, randomized, controlled study (EST-1690) conducted by the same investigators compared the same high-dose interferon alpha regimen with either a low-dose regimen of interferon alpha-2b (3 mU/m2 of body surface qd given subcutaneously three times per week for 104 weeks) or observation. Evidence (excision The Intergroup Melanoma Surgical Trial Task 2b compared 2-cm versus 4-cm margins for patients with melanomas that were 1 mm to 4 mm thick.
