NCT ID NCT07101328

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This early-stage trial tests a new drug called LY4152199 in about 215 adults with certain types of blood cancer (like follicular lymphoma or diffuse large B-cell lymphoma) that have already been treated. The drug is designed to help the body's immune cells attack the cancer. The main goals are to find a safe dose and to see if the drug can shrink tumors. Participants may continue treatment as long as they benefit.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
LY4152199 (a drug that helps immune cells attack cancer cells)
What this could lead to
If it works, this could point toward a new treatment option for people with certain types of blood cancer that have not responded to other therapies.
What could go wrong
This is a very early (Phase 1) trial, so the main goal is safety, not proof of effectiveness. The drug may not work or could cause serious side effects.

Phase 1 Dose Escalation (Cohort A) Participants - Must have histologically confirmed relapsed/refractory B-cell malignancy. Phase 1 Dose Optimization (Cohort B) Participants \- Must have histologically confirmed relapsed/refractory diffuse large B-cell lymphoma (DLBCL) de novo or transformed from follicular lymphoma (FL). Exclusion Criteria: All Participants * Known or suspected peripheral blood involvement by malignant cells with an absolute lymphocyte count of greater than or equal to (≥) 5000 cells per microliter (μL). * Known or suspected central nervous system (CNS) involvement by systemic lymphoma. * Current or history of CNS disease, such as stroke, epilepsy, CNS vasculitis, or neurodegenerative disease * Any unresolved toxicities from prior therapy greater than National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 Grade 2 at the time of starting trial treatment except for alopecia. * Autologous stem cell transplantation within 100 days of this study for post autologous transplant individuals. * Residual symptoms of neurotoxicity or cytopenias from prior chimeric antigen receptor T-cell therapy (CAR-T) or bispecifics. Exception: Cytopenia related to prior CAR-T or bispecifics allowed if they meet the adequate organ function criteria. * Known or suspected history of macrophage activation syndrome or hemophagocytic lymphohistiocytosis (HLH). * Active second malignancies, unless in remission, with life expectancy greater than 2 years with Sponsor approval. * History of autoimmune disease * Significant cardiovascular disease * Active uncontrolled systemic bacterial, viral, fungal, or parasitic infection (except for fungal nail infection), or other clinically significant active disease process * Vaccination with a live vaccine within 4 weeks prior to signing informed consent form (ICF). * Have current or had a history of severe allergic or anaphylactic reactions to monoclonal antibody therapy (or recombinant antibody-related fusion proteins). * Prior treatment with B-cell activating factor receptor (BAFF-R) directed therapies (e.g., monoclonal antibody, CAR-T or bispecific antibody). * Pregnant and/or planning to breastfeed during the trial or within 90 days of the last dose of study intervention. * Known hypersensitivity to any component or excipient of LY4152199.
