@SuyogCancer Endpoint choice depends on the treatment:
Novel mechanism, drug-free interval possible, OS too long to follow → use PFS.
Later-line moved upfront → use OS + mandatory crossover.
@BenCreelan@BenjaminBesseMD Immunotherapy stops at 2 yrs in clinical trials. If discontinuation caused relapse, PFS should plummet after that — but it doesn't. This points more toward resistance than stopping treatment. No wonder rechallenge ORR isn't great.
@ArndtVogel@HEP_Journal Neoadjuvant ≠ Conversion therapy. The former aims to minimize the risk of progression (ORR is not important!) , while the latter pursues a greater depth of response.
@ChandrakanthMv Comparing concurrent vs. just the 1st step of sequential therapy is an unfair comparison. A positive PFS is no surprise, but it comes at the cost of losing a line of therapy for post-progression survival.
@OscarTahuahua Did they use a placebo control? Both groups should ideally have morning and afternoon infusions to rule out bias. It’s a low-cost measure that would effectively control for the psychological and lifestyle impact of the infusion time itself.

@NiuSanford RTOG 1112 started at 2013. CARES-310 started at 2019. IMbrave 150 result was published at 2020. RTOG 1112 was early terminated at 2021 because of slow enrollment.
