About

This study will treat patients with advanced NSCLC with EGFR or HER2 mutation who have progressed following prior therapy. This is the first time this drug is tested in patients, and so it will help to understand what type of side effects may occur with the drug treatment. It will also measure the levels of drug in the body and preliminarily assess its anti-cancer activity as monotherapy.

Full description

A Phase I/II, Open-Label, Multicenter Study to Assess the Safety, Tolerability, Pharmacokinetics and Anti-tumor Efficacy of Sunvozertinib in Patients with Advanced Non-Small Cell Lung Cancer (NSCLC) with EGFR or HER2 mutation. This study includes dose escalation, dose expansion, food effect (Part A) and dose extension (Part B).

Inclusion criteria

  • Aged at least 18 years old, be able to provide a signed and dated, written informed consent.
  • With documented histological or cytological confirmed locally advanced or metastatic NSCLC with EGFR or HER2 mutations.
  • (ECOG) performance status 0-1.
  • Predicted life expectancy ≥ 12 weeks
  • Patient must have measurable disease according to RECIST 1.1.
  • Patients with brain metastasis (BM) can be enrolled under the condition that BM is previously treated and stable, neurologically asymptomatic and does not require corticosteroid treatment.
  • Adequate organ system function.

Part A Dose expansion: Dose expansion cohort 5: NSCLC patients with EGFR Exon20ins, who have not received prior systemic therapy (treatment naïve).

Part B Dose extension:

  • Patients must have histologically or cytologically confirmed locally advanced or metastatic NSCLC with documented EGFR Exon20ins mutation in tumor tissue from a local CLIA-certified laboratory (or equivalent) or Sponsor designated central laboratory prior to the study entry.
  • Patients should have received at least 1 line, but no more than 3 lines of systemic therapy for metastatic/locally advanced disease.

Exclusion criteria

  • For part B: Patients who have received prior treatment with Poziotinib or TAK788 or other EGFR/HER2 exon20 insertion inhibitors should be excluded. Prior treatment with currently approved EGFR TKIs for sensitizing or T790M resistance mutations, such as gefitinib, erlotinib, osimertinib, afatinib and dacomitinb, are allowed unless the patient had an objective response and subsequent progression assessed by the investigator.
  • Treatment with EGFR or HER2 antibodies, major surgery (excluding placement of vascular access), or onco-immunotherapy (e.g. immune checkpoint inhibitors PD-1, PD-L1, CTLA-4) within 4 weeks before the first administration of Sunvozertinib.
  • Any cytotoxic chemotherapy, investigational agents or other anticancer drugs from a previous treatment regimen or clinical study within 14 days before the first administration.
  • Radiotherapy with a limited field of radiation for palliation within 1 week of the first dose or with a wide field of radiation which must be completed within 4 weeks before the first administration.
  • Receiving (or unable to stop using) medications or herbal supplements known to be potent inhibitors or inducers of CYP3A within 1-2 weeks before the first administration.
  • Any unresolved toxicities from prior therapy greater than CTCAE grade 1 at the time of starting Sunvozertinib with the exception of alopecia and grade 2 prior platinum-therapy related neuropathy.
  • Spinal cord compression or leptomeningeal metastasis.
  • As judged by the investigator, any evidence of severe or uncontrolled systemic diseases, which would jeopardize compliance with the protocol, or active infection including hepatitis B, hepatitis C, human immunodeficiency virus (HIV) and COVID-19 (per local practice).
  • Any of the following cardiac criteria: (1) Mean resting corrected QT interval (QTc) > 470 msec obtained from 3 electrocardiograms (ECGs); (2) Any clinically significant abnormalities in rhythm, conduction or morphology of resting ECG, e.g., complete left bundle branch block, third degree heart block, and second-degree heart block, PR interval > 250 msec. (3) Any factors that increase the risk of QTF prolongation, such as heart failure, hypokalemia, congenital long QT syndrome, family history of long QT syndrome or unexplained sudden death under 40 years of age in first degree relatives or any concomitant medication known to prolong the QT interval; (4) Prior history of atrial fibrillation within 6 months of first administration of Sunvozertinib, except prior drug treatment related and recovered.
  • Past medical history of interstitial lung disease, drug-induced interstitial lung disease, radiation pneumonitis which required steroid treatment, or any evidence of clinically active interstitial lung disease.
  • Refractory nausea and vomiting, chronic gastrointestinal diseases, inability to swallow the formulated product or previous significant bowel resection that would preclude adequate absorption of Sunvozertinib.
  • History of hypersensitivity to active or inactive excipients of Sunvozertinib or drugs with a similar chemical structure or class to Sunvozertinib.
  • Women who are pregnant or breast feeding.
  • Involvement in the planning and conduct of the study.
  • Judgment by the investigator that the patient should not participate in the study if the patient is unlikely to comply with study procedures, restrictions and requirements.
