Tesaro’s niraparib is a highly selective poly(ADP-ribose) polymerase (PARP) 1/2 inhibitor that can induce synthetic lethality in tumor cells with homologous recombination DNA repair deficiencies (HRD), including germline BRCA-mutated tumours.  It received a lot of attention yesterday following the company’s announcement that the phase 3 trial successfully met its primary endpoint.  The trial was expected to readout this month, so it was bang on schedule.

ASCO 2016 Posters 5

Braving the scrum in the ASCO 2016 poster hall

The results generated a lot of discussion and also a bunch (half a dozen!) of questions from readers, since there was a lot noise around the top-line data in the press release, but very little real analysis or context.

I was planning on rolling out the draft posts we have been working on Gems from the Poster Halls, which included one focused on ovarian cancer.  It therefore makes sense to combine the poster analysis with a reader Q&A on ovarian cancer, including a detailed look at Tesaro’s niraparib as there are some important subtleties that many have missed.

Inevitably this ended up as a rather meaty analysis rather than the quick review I originally intended!
