About this study

Official title: An Open-Label, Phase 2 Basket Study of Neratinib in Patients With Solid Tumors With Somatic Activating HER Mutations

Read the detailed description

This is an open-label, multicenter, multinational, Phase 2 basket study exploring the efficacy and safety of neratinib as monotherapy or in combination with other therapies in participants with HER (EGFR, HER2) mutation-positive solid tumors. The study has a basket design and includes several cohorts, either defined by an actionable somatic mutation or by actionable mutation and tumor histology, including HER2 mutant breast, HER2 mutant cervical, HER2 mutant salivary gland, and EGFR Exon 18 mutant Non-small cell lung cancers.

The trial will consist of a screening period, a treatment period, and an end of treatment visit occurring when neratinib is discontinued for any reason, a safety follow-up visit occurring 28 days after the last dose of neratinib and a survival follow-up period.

Conditions: Solid Tumors Harboring Somatic HER2 or EGFR Exon 18 Mutations
Being tested: Neratinib, Fulvestrant, Trastuzumab, Paclitaxel
Keywords: Neratinib, Nerlynx, Breast, Solid Tumors, Cancer, HER2 mutations, EGFR mutations, Fulvestrant, Trastuzumab, Cervical, Salivary, ERBB2, Exon 18, Metastatic, HR Positive, Lung, Non-Small Cell Lung Cancer (NSCLC)
Medical subject headings: Neoplasms, Neoplasm Metastasis, Carcinoma, Non-Small-Cell Lung

Questions about this trial

What is this clinical trial studying?

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 5 inclusion and 6 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 12 Mar 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 60 sites in United States, Spain, Israel, France, Italy and 8 more countries. 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?

Yes. Results are posted in the registry (first posted 12 Mar 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Confirmed Objective Response Rate (ORR) by Independent Central Review (Breast Cancer With Prior CDK46i Cohort) (time frame: From enrollment date to first confirmed Complete or Partial Response, whichever came earlier, assessed up to 58 months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01953926, which also lists 10 linked publications.

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 12 Mar 2024.
