Study of MEDI4736 (Durvalumab) With or Without Tremelimumab Versus Standard of Care Chemotherapy in Urothelial Cancer

A phase 3 trial of Durvalumab, Tremelimumab, Cisplatin, Carboplatin and Gemcitabine in bladder & urothelial cancer, run by AstraZeneca, active and no longer recruiting.

Active

Study of MEDI4736 (Durvalumab) With or Without Tremelimumab Versus Standard of Care Chemotherapy in Urothelial Cancer is a phase 3 interventional study registered as NCT02516241 by AstraZeneca, with 1126 participants enrolled, started 2015-11-02 and due to reach its primary completion in 2020-01-27. Interventions recorded: MEDI4736 (Durvalumab), Tremelimumab, Cisplatin, Carboplatin and Gemcitabine. Results have been posted on the registry.

Setting

A Phase III, Randomized, Open-Label, Controlled, Multi-Center, Global Study of First-Line MEDI4736 (Durvalumab) Monotherapy and MEDI4736 (Durvalumab) in Combination With Tremelimumab Versus Standard of Care Chemotherapy in Patients With Unresectable Stage IV Urothelial Cancer

To Assess the Efficacy of Durvalumab + Tremelimumab Combination Therapy Versus SoC in Terms of OS in Full Analysis Setprimarysurvival endpoint

Median 15.1 vs 12.1 months with Combination Therapy compared with Standard of Care; about 3 months longer for half the group.
A median is a midpoint: half the people did better than this and half did worse, so it is not a prediction for any one person.
Put another way, the treated group had about 15 percent lower chance of the event at any given time (hazard ratio 0.85).

The p-value (0.0751) means the difference could plausibly be due to chance.
Overall survival counts deaths from any cause, so it is the most direct measure of whether a treatment helps people live longer.

To Assess the Efficacy of Durvalumab Monotherapy Versus SoC in Terms of OS in PD-L1-High Analysis Setprimarysurvival endpoint

Median 14.4 vs 12.1 months with Monotherapy compared with Standard of Care; about 2.3 months longer for half the group.
A median is a midpoint: half the people did better than this and half did worse, so it is not a prediction for any one person.
Put another way, the treated group had about 11 percent lower chance of the event at any given time (hazard ratio 0.89).

The p-value (0.3039) means the difference could plausibly be due to chance.
Overall survival counts deaths from any cause, so it is the most direct measure of whether a treatment helps people live longer.

PFS, Full Analysis Set -Durvalumab + Tremelimumab Combination Therapy vs SoC and Durvalumab Mono Therapy vs SoCsurrogate endpoint

Median 3.7 vs 2.3 months with Combination Therapy compared with Monotherapy; about 1.4 months longer for half the group.
A median is a midpoint: half the people did better than this and half did worse, so it is not a prediction for any one person.
Other groups: Standard of Care 6.7 months.

This is a surrogate endpoint: it measures the cancer being controlled or absent on scans and tests, which often, but not always, translates into living longer.

Objective Response Rate (ORR), Full Analysis Set -Durvalumab + Tremelimumab Combination Therapy vs SoC and Durvalumab Mono Therapy vs SoCresponse endpoint

36.3 vs 25.7 out of 100 had their tumour shrink with Combination Therapy compared with Monotherapy; 10.6 more per 100.
Roughly one extra person helped for every 9 treated. That is a rough figure taken from the two percentages, not a guarantee for any one person.
Other groups: Standard of Care 49.1 of 100.

A response rate counts how many people had their tumours shrink by a set amount; shrinking is encouraging but does not by itself show that people live longer or feel better.

Caveats

These results apply to the people the trial enrolled: A Phase III, Randomized, Open-Label, Controlled, Multi-Center, Global Study of First-Line MEDI4736 (Durvalumab) Monotherapy and MEDI4736 (Durvalumab) in Combination With Tremelimumab Versus Standard of Care Chemotherapy in Patients With Unresectable Stage IV Urothelial Cancer. People in a different situation may not see the same effect.

Numbers are from the trial as recorded here; see the source links in the table below. This is orientation, not medical advice: ask your team how closely the trial population matches you.
