About this study

Official title: A Phase I/II Study to Evaluate the Safety Clinical and Biological Activity of a Humanized Monoclonal Antibody Targeting Netrin-1 (NP137) in Combination With Standard AZACITIDINE+ VENETOCLAX in Patients With Refractory Acute Myeloid Leukemia

The aim of this study is to investigate the safety and the clinical activities of NP137 when combined with Azacitidine and Venetoclax in patients with refractory acute myeloid leukemia after 2 cycles of Azacitidine and Venetoclax.

Read the detailed description

The dual treatment, VENETOCLAX and AZACITIDINE, is the standard of care for patients with newly diagnosed AML who are ineligible for intensive chemotherapy. However, upfront resistance as well as relapse following initial response demonstrate the need to improve this therapeutic strategy.

NP137 is a first-in-class humanized monoclonal antibody targeting specifically and selectively Netrin-1. Based on data collected from non clinical studies NP137 should act in synergy with VENETOCLAX and AZACITIDINE to reactivate and enhance the apoptotic pathway in AML cells.

The herein proposed study to assess the safety (Safety run in/ phase I part) and the preliminary efficacy signal (extension phase II part) of the NP137 when combined to AZACITIDINE AND VENETOCLAX in patients with refractory acute myeloid leukemia after 2 cycles of Azacitidine and Venetoclax.

This study will be an open-label, Phase I/II trial. the first part, consists to a safety run to assess the security and the tolerability of the drugs combination from the first 6 to 12 first patients enrolled into the study. All patients will receive a fixed dose of NP137 at the RP2D (Recommended Phase 2 Dose) determined from the First in human NP137 study(DL1) . A dose deescalation of NP137 is planned to DL-1 according to the Dose Limiting Toxicities observed during this period. The second part will be will be then conducted as a phase II using an adaptive Bayesian approach allowing to quickly stop treatment without evidence of efficacy. The clinical activity will be assessed based on ELN (European LeukemiaNet) criteria 2027 for the Acute Myeloid Leukemia.

Receives: Drug: NP137; Drug: Azacitidine Injection; Drug: Venetoclax

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Safety run in part : Incidence of Dose Limiting Toxicities (DLT)

    To assess the safety of the proposed therapeutic combination [NP137 + AZACITIDINE VENETOCLAX] according to the incidence of Dose Limiting Toxicities (DLT) as defined per protocol.

    Measured: 4 weeks

  2. Phase II part : Objective Response Rate (ORR)

    To investigate the clinical activity of the proposed therapeutic combination [NP137 + AZACITIDINE + VENETOCLAX] through the Objective Response Rate (ORR) over the 4 cycles of AZACITIDNE +VENETOCLAX+ NP137 administration.

    ORR will be defined as the proportion of patients with a complete remission (CR) or complete remission with incomplete hematologic recovery (CRi), as best overall response over the 4 cycles of the study combination.

    Measured: 16 weeks

Secondary outcomes (15)
  1. Adverse events

    Incidence of any adverse events graded according to NCI-CTCAE V5.0

    Measured: from the date of first intake of study drug until to 90 days after study drug discontinuation, (at least up to 12 months for the last patient in)

  2. Duration of response

    Measurement of the duration of response (CR/CRi)

    Measured: from the time of first documented response until the first progression or death, (at least up to 12 months for the last patient in)

  3. Best overall response (BOR)

    Best overall response, is determined by the best response designation. For subjects without documented progression or subsequent anticancer therapy, all available response designations will contribute to the BOR determination :from the date of first intake of study drug until progression or at time of initiation of a new anti-cancer treatment

    Measured: Every 28 days, up to 1 year

  4. Objective Response Rate

    Objective Response Rate after 2 cycles of study treatment defined as the proportion of participants who achieve: complete remission (CR) or complete remission with incomplete hematologic recovery (CRi) after 2 cycles of treatment (2 cycles of A+V including 4 injections of NP137)

    Measured: 8 weeks

  5. Overall survival

    Overall survival measured from the date of treatment start to the date of death from any cause; patients not known to have died at last follow-up are censored on the date they were last known to be alive.

    Measured: Until up to 1 year follow-up of the last patient enrolled

  6. Progression Free survival

    Progression Free survival defined as the time from the initiation of the study treatment until first evidence of disease treatment failure : from the date of first intake of study drug until progression

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing NP137, Azacitidine Injection and Venetoclax in people with Acute Myeloid Leukemia Refractory, run by Centre Leon Berard at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 31 inclusion and 23 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 20 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: low recruitment rate). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety run in part : Incidence of Dose Limiting Toxicities (DLT) (time frame: 4 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Feb 2025.
