Rishabh Jain: Not Just Coffee, Even Pembrolizumab Works Better Before 11 AM

Rishabh Jain, Medical Oncologist at AIIMS, shared a post on X:

“Not just coffee – even pembrolizumab works better before 11 AM

Eur J Cancer 2025 | 9-center retrospective, n=450

1L Pembrolizumab monotherapy in advanced NSCLC

Timing groups:

Early ≤11:00 AM Late >11:00 AM

Results (PSM, n=206 | median f/u 62.5 mo):

  • OS: 43.7 vs 32.4 mo ➝ HR 0.67 (95% CI 0.46–0.97, p=0.03)
  • PFS: 13.8 vs 11.6 mo ➝ NS (HR 0.80)
  • irAEs ≥G3: 26.2% vs 13.6% (p=0.04)

Take-home:

First-dose timing may prime immune activation. Morning infusion → better OS, but higher severe irAEs.

A simple, low-cost tweak worth prospective testing.”
