A Study of JNJ-70218902 in Participants With Advanced Stage Solid Tumors
- Conditions
- Neoplasms
- Interventions
- Drug: JNJ-70218902
- Registration Number
- NCT04397276
- Lead Sponsor
- Janssen Research & Development, LLC
- Brief Summary
The purpose of this study is to determine the recommended Phase 2 dose(s) (RP2D\[s\]) and maximum tolerated dose (MTD) of JNJ-70218902 in Part 1, and to determine the safety of JNJ-70218902 RP2D(s) in Part 2.
- Detailed Description
JNJ-70218902, the investigational drug, has been shown in pre-clinical studies to work by attaching to cancer cells and activating immune cells to kill these cancer cells. This study will be conducted in 2 parts: dose escalation (Part 1) and dose expansion (Part 2) and will enroll adult men with Metastatic Castration-Resistant Prostate Cancer (MCRPC). Study evaluations will include preliminary clinical efficacy, safety, pharmacokinetics, biomarkers and immunogenicity evaluations. This study is divided into 3 periods: screening, treatment and post-treatment. The total duration of the study will be 2.5 years approximately.

Group Intervention Description Part 1: Dose Escalation JNJ-70218902 Participants with metastatic castration-resistant prostate cancer (mCRPC) will receive JNJ-70218902. The dose levels will be escalated sequentially based on the decisions of the Study Evaluation Team (SET) until the recommended Phase 2 Dose (RP2D) has been identified. Part 2: Dose Expansion JNJ-70218902 Participants with mCRPC will receive JNJ-70218902 at the RP2D determined in Part 1.
- Primary Outcome Measures
Name Time Method Part 1 and Part 2: Number of Participants with AEs by Severity Up to 2.5 years Severity will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 5.0 with the exception of cytokine release syndrome (CRS), which will be graded according to the American Society for Transplantation and Cellular Therapy (ASTCT) guidelines. Severity scale ranges from Grade 1 (Mild) to Grade 5 (Death). Grade 1= Mild, Grade 2= Moderate, Grade 3= Severe, Grade 4= Life-threatening and Grade 5= Death related to adverse event.
Part 1 and Part 2: Number of Participants with Adverse Events (AEs) as a Measure of Safety and Tolerability Up to 2.5 years An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study.
Part 1: Number of Participants with Dose-Limiting Toxicity (DLT) Up to 21 days Number of participants with DLT will be assessed. The DLTs are specific adverse events and are defined as any of the following: high grade non-hematologic toxicity, or hematologic toxicity.
- Secondary Outcome Measures
Name Time Method Area Under the Serum Concentration-time Curve From t1 to t2 Time (AUC[t1-t2]) of JNJ-70218902 Up to 2.5 years AUC(t1-t2) is defined as the area under the serum concentration-time curve from time t1 to t2.
Minimum Observed Serum Concentration (Cmin) of JNJ-70218902 Up to 2.5 years Cmin is the minimum observed serum concentration of JNJ-70218902.
Maximum Observed Serum Concentration (Cmax) of JNJ-70218902 Up to 2.5 years Cmax is the maximum observed serum concentration of JNJ-70218902.
Time to Reach Maximum Observed Serum Concentration (Tmax) of JNJ-70218902 Up to 2.5 years Tmax is defined as time to reach maximum observed serum concentration.
Accumulation Ratio (RA) of JNJ-70218902 Up to 2.5 years Accumulation Ratio (RA) is calculated as area under the plasma concentration-time curve from time zero to 24 hours (AUC \[0-24\]) value at steady state divided by AUC (0-24) value after first dose.
Systemic Cytokine Concentrations Up to 2.5 years Cytokines concentration will be measured for biomarker assessment.
Serum Prostate Specific Antigen (PSA) Concentration Up to 2.5 years Serum prostate specific antigen (PSA) concentration will be measured.
Number of Participants With Anti-JNJ-70218902 Antibodies Up to 2.5 years Number of participants with anti-JNJ-70218902 antibodies will be assessed.
Duration of Response (DOR) Up to 2.5 years Duration of response (DOR) will be calculated from the date of initial documentation of a response (PR or better) to the date of first documented evidence of progressive disease, as defined in the PCWG3 or RECIST version 1.1 response criteria, or death due to any cause, whichever occurs first.
Area Under the Concentration-time Curve From Time Zero to End of Dosing Interval (AUCtau) of JNJ-70218902 Up to 2.5 years AUCtau is the measure of the serum drug concentration from time zero to end of dosing interval.
Objective Response Rate (ORR) Up to 2.5 years ORR is defined as the percentage of participants who have a Partial Response (PR) or better according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 without evidence of bone progression according to Prostate Cancer Working Group 3 (PCWG3).
