  • Has uncontrolled brain metastases. Patients are allowed if brain metastasis has been previously treated with surgery, whole brain irradiation, and/or stereotactic radiosurgery and are considered controlled (controlled by the dose ≤10 mg/day of prednisone or equivalent) at the time of the first dose of investigational product. Radiological evaluation of brain metastasis will be performed only if the patient has symptoms. For asymptomatic patients, brain imaging during screening is not required.

About this study

Official title: A Phase 2 Multicenter, Open-Label, Single-Arm Study to Evaluate the Safety and Efficacy of Oral NRC-2694-A in Combination With Paclitaxel in Patients With Recurrent and/or Metastatic Head and Neck Squamous Cell Carcinoma, Who Progressed on or After Immune Checkpoint Inhibitor Therapy

This is a Phase 2, open-label, multicenter, single-arm study of NRC-2694-A in combination with paclitaxel in patients with R/M HNSCC with progression on or after ICI therapy.

A total of approximately 46 male and female patients will be enrolled. This sample size is based on Simon's 2-stage design with historical control ORR of 30% and a target ORR of 50%.

Read the detailed description

Patients with recurrent and/or metastatic unresectable Head and Neck Cancer have a poor prognosis and limited treatment options. Pembrolizumab and Nivolumab, both ICIs (Immune Checkpoint Inhibitors), are approved therapies for this condition. However, no approved treatment options exist for patients who progress on ICI therapies. Hence, there is an unmet medical need post-failure of ICI therapy. NRC-2694-A is an orally administered small-molecule tyrosine kinase inhibitor. It was discovered and developed by NATCO Pharma Ltd. NRC-2694-A demonstrated response in HNSCC patients in a Phase-I study as a monotherapy. This was further substantiated in a Phase-II study in combination with cisplatin/carboplatin and paclitaxel.

What is this clinical trial studying?

A Phase 2 study testing NRC-2694-A and Paclitaxel in people with Carcinoma and Recurrent and/or Metastatic Head and Neck Squamous Cell Carcinoma, run by NATCO Pharma Ltd. at 13 sites in 2 countries.

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 11 inclusion and 20 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 23 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 sites in United States, India. 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 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?

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 Praveen Myneni, MBBS (+91 40 23547532, drpraveen@natcopharma.co.in), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To determine if NRC-2694-A administered orally in combination with paclitaxel demonstrates objective response in patients with R/M HNSCC, who have had radiological progression on or after treatment with ICI therapies like pembrolizumab or nivolumab (time frame: Baseline through approximately up to 24 weeks). 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 23 Jan 2026.
