Trial summary

NPX372 is an antibody drug (protein drug) that blocks a specific protein which is found to be increased on the surface of cancer cells called B7-H7 and, at the same time, binds to immune cells (T cells) through a receptor called CD3. The effect of this binding is to activate T cells to kill cancer cells with B7-H7. Read more about this study

About this study

Official title: A Phase 1 Dose-Escalation Study of NPX372, a Bispecific Antibody Targeting B7-H7 and CD3, in Selected Solid Tumor Malignancies

NPX372 is an antibody drug (protein drug) that blocks a specific protein which is found to be increased on the surface of cancer cells called B7-H7 and, at the same time, binds to immune cells (T cells) through a receptor called CD3. The effect of this binding is to activate T cells to kill cancer cells with B7-H7.

In this research study we are:

  • Evaluating the safety and possible effectiveness of NPX372.
  • Identifying a safe and tolerable dose or doses for further study.

Participants who are treated will receive an intravenous (IV) infusion of NPX372 if their disease has not progressed, and be closely monitored by the treating physicians.

Read the detailed description

NPX372 is being developed as a therapeutic in solid tumor malignancies including non-small cell lung cancer (NSCLC), renal cell carcinoma (RCC), colorectal carcinoma (CRC), pancreatic adenocarcinoma (PDAC), biliary tract tumors, ovarian carcinoma, and gastric/gastro-esophageal carcinoma. This study is a Phase 1 study with primary dose-escalation occurring in the aforementioned solid tumor malignancies (main cohorts). Backfill cohorts from a selected subset of these tumor types will be utilized to enrich for dose optimization in participants whose tumors have high B7-H7 expression determined by prospective screening of archival tissue.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • NPX372Drug

    NPX372 is administered by IV infusion. The first cycle will be 3 weeks long and NPX372 will be given on the first day and one week later during this 3-week period. For most dose levels, the first day's dose (C1D1) will be a lower dose, which will serve as a "priming dose". The full dose will start on the second dose. After the first two doses, NPX372 will be administered every other week for up to 6 months. After that time, NPX372 will be given about once a month. Treatment may continue for up to 2 years as long as the patient is deriving benefit.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing NPX372 in people with Metastatic Malignant Neoplasm, run by NextPoint Therapeutics, Inc. at 6 sites in United States.

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 16 inclusion and 15 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: looking for participants now, as of the sponsor's last update on 8 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in United States. 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 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.

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

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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

Contact Trials nextpointtx ((508) 214-1115, trials@nextpointtx.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of Dose Limiting Toxicity (DLT) (time frame: From first dose through 21 days). The study lists 6 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 8 Sep 2026.
