Up to Day 3

The AUC (0-infinity) is the area under the plasma concentration-time curve from time zero to infinite time, calculated as the sum of AUC(last) and C(last)/lambda(z); wherein AUC(last) is area under the plasma concentration-time curve from time zero to last quantifiable time, C(last) is the last observed quantifiable concentration, and lambda(z) is elimination rate constant.

SAD: Apparent Elimination Half-life (t1/2)
Up to Day 3

t1/2 is apparent elimination half-life of JNJ-64264681 associated with the terminal slope (z) of the semi-logarithmic drug concentration-time curve.

MAD: Apparent Elimination Half-life (t1/2)
Up to Day 13

t1/2 is apparent elimination half-life of JNJ-64264681 associated with the terminal slope (z) of the semi-logarithmic drug concentration-time curve.

MAD: Accumulation Ratio
Up to Day 13

MAD: Accumulation Ratio obtained by dividing AUC of JNJ-64264681 at two different time points.

ArmTypeDescription
Part A: Dose escalation: JNJ-64264681 and JNJ-67856633EXPERIMENTALParticipants will receive JNJ-64264681 and JNJ-67856633 will be administered together until disease progression, intolerable toxicity, withdrawal of consent, or the investigator.
Part B: Cohort Expansion: JNJ-64264681 and JNJ-67856633EXPERIMENTALParticipants will receive JNJ-64264681 and JNJ-67856633 at the recommended Phase 2 dose (RP2D) determined in Part 1.
JNJ-64264681: Dose Escalation and ExpansionEXPERIMENTALParticipants will receive oral administration of JNJ-64264681 capsule at a dose assigned by the sponsor Study Evaluation Team (SET), based on the available safety, pharmacokinetics, and pharmacodynamics data in dose escalation treatment group (Part 1); and recommended Phase 2 dose (RP2D) determined in Part 1 in cohort expansion treatment group (Part 2).
Single Ascending Dose (SAD)EXPERIMENTALThe SAD part will consist of 6 escalating dose cohorts and 1 fed cohort of healthy male participants, 2 dose escalating cohorts of healthy female participants, and 1 solid dose formulation (capsule) cohort of healthy male participants, who will be dosed after completion of the dose escalation cohorts. Participants in each cohort (except for the solid dose formulation cohort) will receive JNJ-64264681 or Placebo on Day 1, orally. In the solid dose formulation cohort, participants will receive JNJ-64264681 capsule on Day 1. Doses for the female cohorts and fed cohort will be selected based on safety, tolerability, pharmacokinetics (PK),and pharmacodynamic (PD) data from preceding cohorts and the dose for the solid dose formulation cohort will be selected and approximately equal to a dose previously studied in the single ascending dose cohorts.
Multiple Ascending Dose (MAD)EXPERIMENTALThe MAD part will consist of 3 dose escalation cohorts of males and females. Participants will receive once-daily oral doses of JNJ-64264681 or placebo for 10 consecutive days.

Frequently asked questions about JNJ-64264681

What is JNJ-64264681 used for?

JNJ-64264681 is an investigational small molecule being studied for the treatment of non-Hodgkin lymphoma and chronic lymphocytic leukemia. It has also been evaluated in healthy volunteers to assess its safety, tolerability, and pharmacokinetics. The drug is currently in Phase 1 clinical development and is not yet approved by regulatory authorities.

Who makes JNJ-64264681?

JNJ-64264681 is being developed by Johnson & Johnson, a multinational pharmaceutical company traded on the New York Stock Exchange under the ticker symbol JNJ. The company is conducting clinical trials to evaluate the drug's safety and efficacy in patients with certain blood cancers.

What phase is JNJ-64264681 in?

JNJ-64264681 is in Phase 1 clinical development. All three clinical trials involving the drug have been completed, including studies in healthy volunteers and in patients with non-Hodgkin lymphoma and chronic lymphocytic leukemia. The drug remains investigational and has not received FDA approval.

What clinical trials is JNJ-64264681 in?

JNJ-64264681 has been studied in three completed Phase 1 trials. NCT03607513 evaluated the drug in healthy participants in Belgium. NCT04210219 studied it in patients with non-Hodgkin lymphoma and chronic lymphocytic leukemia across multiple countries. NCT04657224 evaluated JNJ-64264681 in combination with another investigational drug, JNJ-67856633, in the same patient populations.

Is JNJ-64264681 the same as JNJ-67856633?

No, JNJ-64264681 and JNJ-67856633 are two different investigational drugs. They were studied together in a Phase 1 clinical trial (NCT04657224) for the treatment of non-Hodgkin lymphoma and chronic lymphocytic leukemia, but they are distinct compounds being developed by Johnson & Johnson.
