To explore potential approaches for reducing CAR T-cell-related toxicities with axi-cel, several safety expansion cohorts were added to the pivotal ZUMA-1 trial. ZUMA-1 Cohort 3 was an exploratory safety cohort that investigated the use of the IL-6 receptor blocking antibody tocilizumab and anticonvulsant levetiracetam as prophylaxis against CRS and NEs in patients treated with axi-cel.

Hypomethylating agents (HMAs) have shown efficacy as salvage therapy by inducing an immune response and improving donor chimerism for myeloid neoplasm post-HCT.

The objective of this report is to delineate the iterative process of adapting an in-person sexual health intervention into a self-administered digital application called \"Sexual Health and Intimacy Following Transplant (SHIFT)\" and the refinement of SHIFT using stakeholder feedback. We used a five-step development model to adapt SHIFT that included: (1) implementation of a multimodal bio-psycho-social conceptual framework, (2) development of a comprehensive intervention manual and SHIFT content, (3) translation of the intervention manual into an interactive storyline with a focus on enhancing patient engagement, (4) creation of initial SHIFT wireframes, and (5) refinement of SHIFT through iterative alpha and beta testing. At each step, key stakeholders including HSCT survivors, HSCT clinicians, and experts in sexual health, psychology, and digital health provided iterative feedback. We adapted SHIFT based on our conceptual framework, prior in-person intervention work, and iterative stakeholder feedback in each application development stage. SHIFT incorporates medical information, educational materials, intimacy exercises, and activities to address the multiple etiologies of sexual health concerns in HSCT survivors. SHIFT includes strategies to enhance engagement including gamification, personalization, and incorporation of video from HSCT survivors and clinicians. Based on stakeholder feedback, SHIFT was refined with a focus on inclusivity of gender, sexual orientation, relationship status, and body image concerns. SHIFT is novel, patient-centered digital application to address sexual dysfunction in HSCT survivors. Iterative feedback from key stakeholders including HSCT survivors guided SHIFT adaptation and refinement, to optimize patient engagement and ensure inclusivity.
