What was measured

The objective response rate was a secondary efficacy endpoint of the study and was defined by the percentage of patients in the study population with a best overall response of Complete Response (CR) or Partial Response (PR) as assessed by the investigator. Best overall response was defined per RECIST (version 1.1) recorded from randomization until progression or end of study. RECIST (v 1.1) criteria does not require confirmation of response, but an additional, more stringent analysis was also conducted, with designation of CR (or PR) requiring confirmation of response at least 4 weeks following the initial assessment of CR (or PR). Stable disease (SD) required an assessment of SD at least 6 weeks after starting treatment. Subjects with insufficient data for response classification were classified as Not Evaluable for best overall response, and as a non-responder for objective response, in the ITT population. Treatment groups are as indicated for the primary outcome of OS.

Groups in this outcome

MM-398 Arm A (Mono Therapy Comparison)

• MM-398 120 mg/m2 IV on Day 1of a 3 weekly cycle Patients who were homozygous for UGT1A1\*28 allele received the first cycle of therapy at a reduced dose of 80 mg/m2. If the patient did not experience any drug related toxicity after the first administration of MM-398, from cycle 2 onwards, the dose could be increased in increments of 20 mg/m2 up to a maximum of 120 mg/m2.

5-FU + Leucovorin (Arm B) (Mono Therapy Comparison)

* 5-FU 2000 mg/m2 IV over 24-hours, every week for 4 weeks (days 1, 8, 15 and 22), followed by 2 weeks of rest, in a 6 week cycle * Leucovorin l + d racemic form 200 mg/m2, or l form 100 mg/m2 IV over 30 minutes, every week for 4 weeks (days 1, 8, 15 and 22), followed by 2 weeks of rest, in a 6 week cycle.

MM-398 + 5-FU + Leucovorin(Arm C) Combo Therapy Comparison

* MM-398 80 mg/m2 IV every 2 weeks Patients who were homozygous for UGT1A1\*28 allele and were randomized to Arm C, received the first cycle of therapy at a reduced dose of 60 mg/m2. If the patient did not experience any drug related toxicity after the first administration of MM-398, from cycle 2 onwards, the dose could be increased to 80 mg/m2. * 5-FU 2400 mg/m2 IV over 46-hours, and * Leucovorin l + d racemic form 400 mg/m2, or l form 200 mg/m2 IV over 30 minutes, every 2 weeks

5-FU + Leucovorin (Combo Therapy Comparison)

* 5-FU 2000 mg/m2 IV over 24-hours, every week for 4 weeks (days 1, 8, 15 and 22), followed by 2 weeks of rest, in a 6 week cycle * Leucovorin l + d racemic form 200 mg/m2, or l form 100 mg/m2 IV over 30 minutes, every week for 4 weeks (days 1, 8, 15 and 22), followed by 2 weeks of rest, in a 6 week cycle.
