The Committee discussed the evidence from the supporting ICON7 trial. It heard from the clinical specialists that the strengths of this trial were that it included some UK patients, and used the most appropriate definitions of progression, disease staging and surgical debulking. The clinical specialists stated that patients in the optimal debulking subgroups differed between the GOG‑0218 and ICON7 trials. The clinical specialists considered that this is shown by fewer patients in the group with optimally debulked cancer in GOG‑0218 having complete resection (that is, no visible disease) than in ICON7. The Committee also heard from the clinical specialists that this might be because another trial, conducted at the same time as GOG‑0218, may have enrolled the patients who had complete resection. The Committee noted that the information on the proportion of patients with stage 3 and 4 disease in ICON7 who had completely resected disease was not available, and that the marketing authorisation for bevacizumab did not specify complete or incomplete resection. The Committee also noted that, in ICON7, no patient crossover was allowed after disease progression. The Committee was aware of the disadvantages of ICON7 relative to the NICE decision problem, including its open-label design and inclusion of some patients with stage 1 and 2 cancer, which is not covered by the marketing authorisation for bevacizumab. In addition, the trial used a lower dose and shorter duration of bevacizumab treatment than is now licensed. Nevertheless, 81% of the patients were covered by the marketing authorisation and the Committee considered that the results from the trial contributed to the body of knowledge about the efficacy of bevacizumab plus paclitaxel and carboplatin for advanced ovarian cancer.
