Summary of HORIZON Interim Data
Melflufen continues to demonstrate promising activity in patients with RRMM, many of whom also have EMD. According to these interim study results, patients demonstrated an ORR of 28% and a clinical benefit rate (CBR) of 40%.
Median PFS is 4.0 months in the ongoing study and duration of response (DOR) is 4.4 months. The majority of patients evaluated (86%) achieved SD or better.
Treatment was generally well tolerated with manageable toxicity, nonhematologic AEs were infrequent and the rate of discontinuation due to AEs was low. Treatment-related SAEs occurred in 20% of patients and were most commonly febrile neutropenia (5%) and thrombocytopenia (2%).
The median age of patients in the clinical study was 64 years. 62% of patients in the study had high-risk cytogenetics, 29% of patients were ISS stage III and 60% of the patients had EMD. The median number of prior lines of therapy was five and the median time since initial diagnosis was 6.2 years.

According to an abstract of data from ANCHOR, of the 10 patients in the arm receiving melflufen with Darzalex there was a 100 percent overall response rate (ORR) at the 30mg dose cohort and a 50 percent response rate at the 40mg cohort. For the five receiving melflufen and bortezomib, the response rate was 100 percent in the 30mg cohort and zero percent at the 40mg dose.
Meanwhile, the company is planning to pursue accelerated FDA approval based on the HORIZON study, with a regulatory filing anticipated in early 2020. According to the EHA abstract for that study, the median PFS for the 95 patients treated as of the Feb. 6 cutoff was four months, with a 10 month median overall survival (OS) and an ORR of 30 percent. Data presented at ASH from a previous cutoff date showed a 33 percent ORR.
