Verastem Oncology Inc. CEO Dan Paterson said he is “not expecting a huge bolus [of ovarian cancer patients] at the beginning” of Avmapki/Fakzynja’s launch, but momentum will build over time. “Based on our market research, this [drug] is the most likely thing for them to go on next,” he added, noting that patients tend to be on the drug for an average of 18 months.
