Ipilimumab For Advanced, Refractory Melanoma: A Report Of The Israeli Cohort Of Expanded Access Program

e20039 Background: As the first agent to show survival advantage in metastatic melanoma, Ipilimumab (Yervoy, BMS) is being gradually introduced into health services worldwide. Itu0027s unique immune mediated side effects requires the incorporation of follow-up guidelines to prevent toxic sequella. We report on safety and efficacy results of refractory melanoma patients (pts) treated on an international expanded access program of Ipilimumab. Methods: Between 4/2010 and 12/2011 183 pts were treated. Pts received Ipilimumab 3 mg/kg q3w for 4 doses. Pts with evidence of clinical benefit at week 12 (CR, PR or SD), were eligible for re-induction upon progression. Results: All pts were pretreated for metastatic disease (median:1 line,range 1-5). 140 pts(77%) had M1c disease, 63 pts(34%) had brain metastasis and 84 (46%) had LDH above ULN, reflecting poor prognostic characteristics of this cohort. Patients received 3.6 doses of Ipilimumab on average. 11% received less than 4 cycles due to toxicity. Grade 3/4 immune-r...
