Osimertinib clinical trials, in English

Osimertinib (Tagrisso) records typically require an EGFR mutation listed in the protocol. Adjuvant, first-line, and post-progression studies are different NCT numbers. We do not interpret your NGS report. Search the same name on ClinicalTrials.gov.

Phase 2: testing Osimertinib for Advanced Lung Non-Small Cell Carcinoma

This phase II trial studies how well osimertinib works in treating patients with non-small cell lung cancer with EGFR exon 20 insertion mutation that is stage IIIB-IV or has come back after a period of improvement (recurrent). Osimertinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Phase 2: testing Osimertinib for Metastatic Non-small Cell Lung Cancer

This study will compare the effectiveness of osimertinib alone with the combination of osimertinib and chemotherapy (carboplatin and pemetrexed) in people with metastatic lung cancer that has a change (mutation) in the gene EGFR. Osimertinib alone is the usual treatment for metastatic EGFR-mutant lung cancer.

Phase 1 / Phase 2: testing quaratusugene ozeplasmid for Carcinoma, Non-Small Cell Lung

The purpose of this randomly assigned study is to determine the safety and how well it works of quaratusugene ozeplasmid (Reqorsa) added to osimertinib in NSCLC patients with activating EGFR mutations who have progressed while on treatment with osimertinib. Quaratusugene ozeplasmid consists of non-viral lipid nanoparticles that encapsulate a DNA plasmid with the TUSC2 tumor suppressor gene and is the first systemic gene therapy for cancer.

Phase 1: testing Osimertinib for Metastatic Lung Non-Small Cell Carcinoma

This phase Ib trial is to find out the best dose, possible benefits and/or side effects of osimertinib and tegavivint as first-line therapy in treating patients with EGFR-mutant non-small cell lung cancer that has spread to other places in the body (metastatic). Osimertinib and tegavivint may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Phase 2: testing Osimertinib for Lung Non-Small Cell Carcinoma

This phase II trial tests how well biologically guided radiation therapy (BgRT) and stereotactic body radiation therapy (SBRT) with osimertinib works for the treatment of EGFR positive non-small cell lung carcinoma that has spread from where it first started (primary site) to a limited number of anatomic sites (oligoprogressive). BgRT is radiation that uses specialized imaging to during treatment to target the active tumor and direct radiation to tumors in order to kill and shrink tumor cells.

This single-site, biomarker-enriched, randomly assigned Phase II study will evaluate osimertinib with or without cyclosporine A (CsA) in metastatic epidermal growth factor receptor (EGFR )-mutant non-small cell lung cancer (NSCLC) \[exon 19 deletion or L858R\]. All consented, baseline circulating tumor DNA (ctDNA)-positive patients receive a 3-week osimertinib run-in; those with persistent ctDNA ("shedders") are randomly assigned 1:1 to continue osimertinib or osimertinib+CsA.

Phase 2: testing Osimertinib for Non-Small Cell Lung Cancer

The goal of this clinical trial is to learn whether adding stereotactic radiosurgery (SRS) or fractionated stereotactic radiotherapy (SRT), delivered on a linear accelerator (LINAC), to osimertinib improves control of brain metastases in adults with stage IV non-small cell lung cancer (NSCLC) carrying a sensitizing EGFR mutation (exon 19 deletion or exon 21 L858R) whose brain metastases cause neurological symptoms (present at diagnosis or arising during osimertinib treatment). The main questions it aims to answer are: * What proportion of participants achieve an intracranial objective response (complete or partial response by RANO-BM criteria)?

FAQ: Osimertinib studies

Are there recruiting Osimertinib clinical trials?

This snapshot currently includes 26 recruiting records that name Osimertinib (or an alias) as an intervention. Also searched as Tagrisso. Confirm the intervention list on ClinicalTrials.gov; names can appear in combination studies.

Does a Osimertinib listing mean the drug is approved for that use?

No. ClinicalTrials.gov lists research studies. An NCT number is not prescribing information and is not an FDA approval for you.

Is PlainTrials affiliated with the maker of Osimertinib?

No. Brand and generic names are copied from public registry intervention fields so you can find the matching NCT record.
