Study Endpoints

Primary Endpoints

Part 1: Number of Participants with Adverse Events (AE) by Severity
Up to approximately 2 years 10 months

An AE is any untoward medical occurrence in a participant administered a pharmaceutical (investigational or non investigational) product. An AE does not necessarily have a causal relationship with the treatment. Severity of AEs will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version (v) 5.0. by using standard grades as follows: Grade 1: Mild; asymptomatic or mild symptoms; Grade 2: Moderate; minimal, local or noninvasive intervention indicated; Grade 3: Severe but not immediately life threatening; hospitalization or prolongation of hospitalization indicated; Grade 4: Life-threatening consequences; and Grade 5: Death related to AE.

Part 1: Number of Participants with Dose-Limiting Toxicities (DLTs)
Up to 28 days

High grade hematologic or non-hematologic toxicities with exceptions and/or toxicities leading to treatment discontinuation will be regarded as DLT.

Part 1: Number of Participants with AEs by Severity Related to Delivery Device and/or Procedure
Up to approximately 2 years 10 months

An AE is any untoward medical occurrence in a participant administered a pharmaceutical (investigational or non investigational) product. An AE does not necessarily have a causal relationship with the treatment. Participants with AEs related to delivery device and/or procedure will be reported.

Part 1: Number of Participants who Received Planned Total Dose per Level
Up to approximately 28 days

Number of participants who received planned total dose per level will be reported.

Part 2: Administered Tumor Response Rate
Up to approximately 2 years 10 months

Administered tumor response rate is defined as the percentage of JNJ-1761981 administered lesions that achieve complete response (CR) or partial response (PR).

Frequently asked questions about JNJ-1761981

What is JNJ-1761981 used for?

JNJ-1761981 is an investigational small molecule being developed for the treatment of neoplasms, which are abnormal growths of tissue that can be benign or malignant. It is currently being studied in a Phase 1 clinical trial in participants with solid tumors. The drug is not yet approved and remains in clinical development.

Who makes JNJ-1761981?

JNJ-1761981 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 a Phase 1 clinical trial to evaluate the safety and tolerability of this investigational small molecule in patients with solid tumors.

What phase is JNJ-1761981 in?

JNJ-1761981 is in Phase 1 clinical development. It is an investigational drug, meaning it has not been approved by regulatory authorities. The ongoing Phase 1 trial is recruiting participants with solid tumors in the United States to study the drug's safety, tolerability, and other early-stage outcomes.

What clinical trials is JNJ-1761981 in?

JNJ-1761981 is being studied in one active clinical trial with the identifier NCT07525141, titled 'A Study of JNJ-1761981 in Participants With Solid Tumors.' This Phase 1 trial is recruiting 66 participants aged 18 years and older with neoplasms in the United States. The trial is controlled but not randomized or double-blinded.

Is JNJ-1761981 FDA approved?

JNJ-1761981 is not FDA approved. It is an investigational drug currently in Phase 1 clinical development. The ongoing trial is recruiting participants to evaluate the drug's safety and other characteristics in patients with solid tumors. Approval would require successful completion of clinical trials and regulatory review.
