Thanks, Mark! Enjoyed presenting these first clinical data exploring tumor-targeted CD28 costimulation alongside CD3 directed T cell engagement. Grateful for the collaborative effort from the J&J team, investigators, and especially the patients who made this research possible!
At #ESMO26 we introduced a new word, #RIPTAC, JNJ-6143. Introducing another innovation presented @sitcancer yesterday! FIH Investigational combo of Pasritamig our @JNJInnovMed KLK2xCD3 T-cell agent + our PSMA x CD28 co-stim JNJ-9401. Signal 1 & signal 2 together! #MyCompany

Thank you @sitcancer for the opportunity to share our work at #SITC26! It was a privilege to present these exciting early data and be part of such a fantastic meeting. Grateful to all the patients and collaborators who made this research possible! @drmnstein @CUCancerCenter
Thanks @LauraGrahamMD for a great presentation at #SITC26. Groundbreaking research is always the case at a @sitcancer Annual Meeting!
Great to speak with @OncLive about our #SITC2026 data combining KLK2×CD3 T-cell engagement with PSMA×CD28 costimulation in #mCRPC.
Encouraging early results with deep, durable PSA responses and favorable safety profile. Excited about the potential of this approach!
