Janssen Research & Development, LLC
Brief Summary

The purpose of the study is to identify the maximum tolerated dose (MTD) of JNJ-64619178 in participants with relapsed/refractory B cell non-Hodgkin lymphoma (NHL) or advanced solid tumors and also to identify the recommended Phase 2 dose(s) (RP2Ds) of JNJ-64619178 for NHL and advanced solid tumors (Part 1) and to confirm the tolerability of JNJ-64619178 in participants with lower risk myelodysplastic syndromes (MDS) (Part 2).

Detailed Description

The study is designed to determine the maximum tolerated dose (MTD) of JNJ-64619178, and to select a dose(s) and regimen(s) that may be used in future clinical development. Study evaluations will include safety, pharmacokinetics, biomarkers and efficacy evaluations (Disease Assessments). Adverse events will be evaluated throughout the study. The study is divided into 4 periods: a screening phase, a pharmacokinetic run-in phase, a treatment phase, and a post treatment follow-up phase. An end-of-treatment visit will be completed less than or equal (\<=) 30 days (+7 days) after the last dose of study drug or prior to the start of a new anticancer therapy, whichever comes first.

GroupInterventionDescription
Part 1: Dose escalation and RP2D SelectionJNJ-64619178Participants with solid tumors or non-Hodgkin lymphoma (NHL) will receive JNJ-64619178 orally as per the assigned sequential cohorts and doses will be escalated based on the review of all available data including, but not limited to, pharmacokinetic, pharmacodynamic, safety, and clinical activity. One or more recommended Phase 2 dose(s) (RP2Ds) may be determined for further exploration.
Part 2:Dose Confirmation and ExpansionJNJ-64619178Participants with myelodysplastic syndromes (MDS) will receive JNJ-64619178 at a dose less than or equal to the RP2D selected in Part 1 for 24 weeks, or longer if there is evidence of clinical benefit. The dose level of JNJ-64619178 may be adjusted based on observed toxicities.
Primary Outcome Measures
NameTimeMethod
Part 1 and Part 2: Number of Participants with Dose-limiting Toxicities (DLTs)Approximately 3 years

DLTs are defined as certain non-hematologic and hematologic toxicities of Grade 3 or higher.

Secondary Outcome Measures
NameTimeMethod
Part 1 and Part 2: Maximum Plasma Concentration (Cmax) of JNJ-64619178Approximately 3 years

Cmax is the maximum observed plasma concentration.

Part 1 and Part 2: Apparent Total Systemic Clearance of Drug (CL/F) after Extravascular AdministrationApproximately 3 years

Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.

Part 1 and Part 2: Accumulation Index (RA)Approximately 3 years

Accumulation Index (RA) is calculated as AUC (0-24) value at steady state divided by AUC (0-24) value after first dose.

Part 1 and Part 2: Number of Participants with Adverse Events (AE)Approximately 3 years

AE is any untoward medical occurrence in participant who received study drug without regard to possibility of causal relationship.

Part 1 and Part 2: Number of Participants with Abnormal Vital SignsApproximately 3 years

Number of participants with abnormality in vital signs (temperature, pulse/heart rate, and blood pressure) will be reported.

Part 1 and Part 2: Number of Participants with Laboratory AbnormalitiesApproximately 3 years

Number of participants with laboratory abnormalities (serum chemistry, hematology, and coagulation, and disease-related laboratory abnormalities) will be reported.

Part 1 and Part 2: Area Under the Plasma Concentration Versus Time Curve From Time Zero to End of Dosing Interval (AUCtau)Approximately 3 years

AUCtau is the measure of the plasma drug concentration from time zero to end of dosing interval.

Part 1 and Part 2: Minimum Plasma Concentration (Cmin)Approximately 3 years

Cmin is the minimum observed plasma concentration.

Part 1 and Part 2: Volume of Distribution at Steady-State Influenced by the Fraction Absorbed (Vss/F)Approximately 3 years

Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired blood concentration of a drug. Steady state volume of distribution (Vss) is the apparent volume of distribution at steady state which is estimated by (D/AUC\[0-infinity\])\* (AUMC\[0-infinity\])/(AUC\[0-infinity\]) where D is the dose of study drug, AUMC(0-infinity) is the area under the first moment curve extrapolated to infinity and AUC (0-infinity) is the area under the plasma concentration-time curve from time zero to infinite time. All these parameters will be assessed as influenced by the fraction absorbed.

Part 1 and Part 2: Plasma Decay Half-Life (t1/2)Approximately 3 years

Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.

Part 1 and Part 2: Plasma Concentration of Symmetric Dimethyl-Arginine (SDMA)Approximately 3 years

Plasma concentration of symmetric dimethyl-arginine (SDMA) will be evaluated.

Overall response rate (ORR) is defined as the percentage of participants who have a PR or better. Per Lugano classification, PR is defined as greater than or equal (\>=) 50 percent (%) decrease in size of target lesions.

Part 1 and Part 2: Number of Participants with AE by SeverityApproximately 3 years

Severity will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE). Severity scale ranges from Grade 1 (Mild) to Grade 4 (Life-threatening).

PD (per RECIST 1.1) defined as at least 20% increase in the sum of the longest diameters of index lesions or unequivocal progression of non-index lesions. Per Lugano classification, PD: target lesions larger; clear progression of non-target lesions; or new tumor lesions; new or recurrent bone marrow involvement; splenomegaly + 2 centimeter (cm) or +50%.

Part 1: Percentage of Participants with Solid Tumors Showing Overall Response of PR or BetterApproximately 3 years

Overall response rate (ORR) is defined as the percentage of participants who have a PR or better. PR criteria in solid tumors (RECIST) is \>= 30 percent (%) decrease in the sum of the diameters of all index lesions compared with baseline in 2 observations at least 4 weeks apart, in absence of new lesions or unequivocal progression of non-index lesions.

Part 2: Red Blood Cell (RBC) Transfusion Independence (TI) RateApproximately 3 years

Percentage of participants with TI, defined as being without any transfusion during any consecutive 8 weeks (56 days) between the first dose of study drug and treatment discontinuation.

Part 1: Clinical Benefit RateApproximately 3 years

Clinical benefit rate is defined as percentage of participants who have a complete response (CR), PR and sustained stable disease of 12 weeks or more. Sustained stable disease of 12 weeks or more is defined as participants with stable disease assessment maintained for about 12 weeks or longer from baseline.
