DSMB in oncology usually look at survival results for safety purposes even if primary efficacy is something else like PFS or response.
Survival analysis could be more powerful even with fewer events than PFS if the hazard ratio was different.
that is, power also depends on how the events are distributed between the groups ( and over time).

I haven't followed this but i'd lean toward this being a positive event.
