MAPS

In MAPS, adding the anti-VEGF antibody bevacizumab to chemotherapy lengthened survival by about three months, the first improvement after pemetrexed.

OS 18.8 vs 16.1 months (HR 0.77). Bevacizumab is NCCN-listed for mesothelioma but never received an FDA indication; use varies. Established angiogenesis as a valid target in the disease.

Setting
Unresectable pleural mesothelioma, first line: cisplatin-pemetrexed ± bevacizumab

Phase 3

448 people took part
Overall survivalprimarysurvival endpoint
  • Median 18.8 vs 16.1 months with Chemotherapy + bevacizumab compared with Chemotherapy; about 2.7 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 23 percent lower chance of the event at any given time (hazard ratio 0.77, likely range 0.62 to 0.95).
  • Overall survival counts deaths from any cause, so it is the most direct measure of whether a treatment helps people live longer.
  • These results apply to the people the trial enrolled: Unresectable pleural mesothelioma, first line: cisplatin-pemetrexed ± bevacizumab. People in a different situation may not see the same effect.
