First-in-human Study of a New Treatment (4A10) for Patients With Relapsed or Hard-to-treat Acute Lymphoblastic Leukemia or Lymphoblastic Lymphoma, Focused on Safety and How the Drug Behaves in the Body and Early Signs of Effect. (ALT-101)

A First in Human, Phase 1, Open-Label Study on the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of 4A10 Monotherapy In Patients With Relapsed or Refractory Acute Lymphoblastic Leukemia or Lymphoblastic Lymphoma

ALT-101 is a first-in-human Phase 1 clinical trial testing a new antibody drug called 4A10 in patients with relapsed or hard-to-treat acute lymphoblastic leukemia (ALL) or lymphoblastic lymphoma.

4A10 is a targeted therapy designed to recognize and attach to a specific protein (CD127) found on leukemia cells. Once it binds, it works in two ways: it blocks growth signals that help cancer cells survive, and it helps the immune system find and destroy those cancer cells.

In this study, patients receive 4A10 through an intravenous (IV) infusion once a week. The main goal of the trial is to find out if the drug is safe, what dose can be given, and how the body processes it. Researchers will also look for early signs that the treatment may be working.

The study starts with small groups of patients receiving increasing doses to carefully monitor safety. Each patient is closely observed during the first treatment cycle (about 4-6 weeks) to watch for side effects. If the treatment is helping and is well tolerated, patients may continue treatment for up to six cycles.

Overall, this study is an early step in testing a new, targeted immune-based therapy for difficult-to-treat blood cancers.

Armi e interventi

Gruppo di partecipanti / Arm
Intervento / Trattamento
Sperimentale: Single Arm
Participants receive 4A10 administered by intravenous route according to the protocol-defined dosing schedule in 28-day cycles until disease progression, unacceptable toxicity, withdrawal of consent, or discontinuation per investigator decision.
Droga: 4A10
4A10 (Molecule B4532) is an investigational human Immunoglobulin G Subclass 1 (IgG1) monoclonal antibody that specifically binds CD127 (Interleukin-7 receptor alpha subunit, IL-7Rα). CD127 is a component of the interleukin-7 receptor and the thymic stromal lymphopoietin receptor (TSLPR), which are expressed on T-cell acute lymphoblastic leukemia (T-ALL) and pre-B-cell acute lymphoblastic leukemia (B-ALL) cells.
