Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Drugs - Blinatumomab
Treatment: Drugs - Pembrolizumab

Experimental: Cohort Ia: Blinatumomab 9/28 µg/day + Pembrolizumab - Participants received blinatumomab administered as a continuous intravenous infusion (CIVI) for 8 weeks followed by a 28-day treatment-free interval. Participants with stable disease or better may have received a second 28-day consolidation cycle. The starting dose of each cycle was 9 µg/day for the first 7 days then 28 µg/day for the remaining days of treatment.

Starting on Day 15 participants also received 200 mg pembrolizumab administered by intravenous (IV) infusion every 3 weeks (Q3W) until disease progression or for up to 35 cycles.

Experimental: Cohort IIa: Blinatumomab 9/28/56 µg/day + Pembrolizumab - Participants received blinatumomab administered as a continuous intravenous infusion for 8 weeks followed by a 28-day treatment-free interval. Participants with stable disease or better may have received a second 28-day consolidation cycle. The starting dose of each cycle was 9 µg/day for the first 7 days, 28 µg/day for 7 days then 56 µg/day for the remaining days of treatment.

Starting on Day 19 participants also received 200 mg pembrolizumab administered by IV infusion Q3W until disease progression or for up to 35 cycles.

Experimental: Cohort IIIa: Blinatumomab 9/28/112 µg/day + Pembrolizumab - Participants received blinatumomab administered as a continuous intravenous infusion for 8 weeks followed by a 28-day treatment-free interval. Participants with stable disease or better may have received a second 28-day consolidation cycle. The starting dose of each cycle was 9 µg/day for the first 7 days, 28 µg/day for 7 days then 112 µg/day for the remaining days of treatment.

Starting on Day 19 participants also received 200 mg pembrolizumab administered by IV infusion Q3W until disease progression or for up to 35 cycles.

Experimental: Expansion Cohort - This cohort will test the maximum tolerated dose of blinatumomab in combination with pembrolizumab identified in Part 1 of the study.


Treatment: Drugs: Blinatumomab
Up to 2 cycles of blinatumomab may be given, where cycle 1 lasts 8 weeks, and cycle 2 lasts 28 days. The treatment is given as a continuous intravenous infusion.

Treatment: Drugs: Pembrolizumab
One cycle of pembrolizumab is a 200 mg IV injection lasting 30 minutes. One cycle will be given every 3 weeks until disease progression, or for a maximum of 35 cycles.
