Treatment Arms

ArmTypeDescription
Part 1 - Dose Escalation and BackfillsEXPERIMENTALAim: Doses of LNCB74 will be escalated to determine the maximum tolerated dose (MTD), maximum administered dose (MAD) and/or recommended Phase 2 dose (RP2D). One or more dose levels will be backfilled for safety and additional biomarker data.
Part 2 - Dose Expansion / OptimizationEXPERIMENTALAim: The objectives of the Part 2 Dose Expansion/Optimization are: i) to evaluate safety, tolerability, anti-tumor activity, and pharmacodynamics of LNCB74 in a more homogenous population and ii) characterize the minimally safe and effective dose in a particular tumor type and determine recommended Phase 2 dose(s) (RP2D).

Interventions

NameTypeDescription
LNCB74DRUGLNCB74 is an antibody drug conjugate being evaluated as a potential treatment for participants with advanced solid tumors. Participants will receive LNCB74 into the vein (IV; intravenously) in 21-day dosing cycles. Participants will continue treatment in the absence of unacceptable toxicities and unequivocal disease progression.

Frequently asked questions about LNCB74

What is LNCB74 used for?

LNCB74 is an investigational small molecule being developed for the treatment of ovarian cancer. It is also being studied in other advanced or metastatic solid tumors, including breast cancer, endometrial cancer, biliary tract cancer, and non-small cell lung cancer. The drug is currently in Phase 1 clinical development.

What does LNCB74 target?

LNCB74 targets B7-H4, a protein that is part of the B7 family of immune checkpoint molecules. By targeting B7-H4, the drug aims to modulate the immune response against tumors. This mechanism is being evaluated in a Phase 1 clinical trial for advanced solid tumors.

Who makes LNCB74?

LNCB74 is being developed by NextCure, Inc., a biopharmaceutical company. The company's stock is traded under the ticker symbol NXTC. NextCure is conducting a Phase 1 clinical trial to evaluate the safety and efficacy of LNCB74 in patients with advanced solid tumors.

What phase is LNCB74 in?

LNCB74 is in Phase 1 clinical development. It is an investigational drug and has not been approved by the FDA. The ongoing Phase 1 trial is recruiting patients to evaluate the drug's safety, tolerability, and preliminary efficacy in advanced solid tumors.

What clinical trials is LNCB74 in?

LNCB74 is being studied in a Phase 1 clinical trial with the identifier NCT06774963. This trial is titled 'A Phase 1 Study of LNCB74 in Advanced Solid Tumors' and is currently recruiting participants in the United States. The trial aims to enroll 145 patients with various advanced solid tumors.

Is LNCB74 the same as B7-H4?

No, LNCB74 is not the same as B7-H4. LNCB74 is the drug candidate, while B7-H4 is the molecular target that the drug binds to. B7-H4 is a protein expressed on tumor cells, and LNCB74 is designed to interact with this target to potentially treat cancer.
