A Phase I Open-label, Multicenter Dose Escalation Study to Assess the Safety, Tolerability and Pharmacokinetics (PK) of PLB1001 in Patients With Met-positive (Met+) Advanced Non-small Cell Lung Cancer (NSCLC) (NCT02896231)

This phase I, first-in-human dose-escalation study was conducted to determine the maximum tolerated dose (MTD), recommended phase II dose (RP2D), dose-limiting toxicities (DLTs), pharmacokinetics (PK) profile, and preliminary antitumor activity of PLB1001.
  • Drug: PLB1001
    PLB1001 is a capsule in the form of 25 mg and 100mg, twice daily.
    • Bozitinib
Ages eligible for Study
18 Years and older
Genders eligible for Study
Accepts Healthy Volunteers
Inclusion Criteria:
  • Signed Informed Consent Form
  • Age≥18 years
  • Histologically or cytologically confirmed advanced non-small cell lung cancer
  • Must have evidence of c-Met positivity from the results of molecular pre-screening evaluations
  • At least one measurable lesion as per RECIST v1.1
  • Patients must have recovered from all toxicities related to prior anticancer therapies to grade ≤ 1
  • ECOG Performance Status of 0-2
Exclusion Criteria:
  • Previous or current treatment with a c-Met inhibitor or HGF-targeting therapy
  • Symptomatic central nervous system (CNS) metastases that are neurologically unstable or requiring increasing doses of steroids to control, and patients with any CNS deficits.
  • Clinically significant, uncontrolled heart diseases. Unstable angina History of documented congestive heart failure (New York Heart Association functional classification > II) Uncontrolled hypertension defined by a Systolic Blood Pressure (SBP) ≥ 140 mm Hg and/or Diastolic Blood Pressure (DBP) ≥ 90 mm Hg Arrhythmias
  • Active peptic ulcer disease or gastritis
  • Adverse events from prior anti-cancer therapy that have not resolved to Grade ≤ 1, except for alopecia
  • Major surgery within 4 weeks prior to starting PLB1001
  • Previous anti-cancer and investigational agents within 4 weeks before first dose of PLB1001. If previous treatment is a monoclonal antibody, then the treatment must be discontinued at least 6 weeks before first dose of PLB1001.
  • Pregnant or nursing women
  • Involved in other clinical trials < 30 days prior to Day 1
This is a Phase I, open-label, multicentre study of PB1001 administered orally to patients with Met-positive (Met+) advanced NSCLC. The study includes a Dose-escalation Part (part A)and a Dose Expansion Part(part B). The aim of the part A is to estimate the MTD and to identify the dose limited toxicity(DLT) and the recommended phase II dose (RP2D) for PLB1001 single agent as well as to determine the PK/PD profile .Once response has been observed in certain dose level ,then followed by the expansion part to further assess the clinical efficacy and safety of PLB1001 single agent. Aprox. 40 patients will be enrolled in PART A, while 20-30 patients for expansion cohort .

PLB1001 is a potent selective c-Met inhibitor. PLB1001 acts on cancer by blocking abnormal cmet-mediated signalling, leading to profound tumour growth inhibition in xenografts of non-small cell lung cancer (NSCLC) tumours. Preliminary data from a c-Met inhibitor INC 280 has provided possibility on the safety and clinical activity of PLB1001 monotherapy in this patient population.
