Run by Janssen Research & Development, LLC · NCT07572006 · Data updated 2026-11-12

This study tests JNJ-95804306 in people with relapsed or refractory hematologic cancers to find a safe dose and see if it helps control the disease when given alone or with standard therapy.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults with relapsed or refractory AML/MDS (Arm A) or CLL/SLL (Arm B) who have exhausted or declined standard options and meet specific health criteria.

Probably not a fit

Patients with rapidly progressing disease, significant comorbidities, or inability to tolerate experimental therapies may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This Phase 1 trial has two parts: a dose-escalation portion to determine a safe and potentially effective dose (RP2D) of JNJ-95804306, and a dose-expansion portion to further assess safety and look for anti-tumor activity at the RP2D with or without standard-of-care therapy in hematological malignancies. Participants include those with AML/MDS in Arm A and CLL/SLL in Arm B who have exhausted other treatment options. The study will explore safety, tolerability, and preliminary signals of efficacy to guide future trials. Sites are in Indiana, Michigan, and New Jersey.

Why it matters

Potential benefit: If successful, participants might experience disease stabilization or tumor shrinkage and benefit from receiving a novel therapy.

How similar studies have gone: Earlier Phase 1 studies of similar investigational agents in blood cancers have shown manageable safety and early anti-tumor activity in some patients, though this approach is still exploratory.
