Detailed Description

This is a multicenter, open-label, single-arm, phase II Study to Evaluate the safety, tolerability, pharmacokinetics and preliminary Efficacy of intermittent oral dosing of CM082 tablets in Chinese patients with wAMD. The study will be performed in two different parts, dose-escalation phase (Part 1) and dose-expansion phase (Part 2). Subjects will receive CM082 orally twice daily for two weeks followed by two weeks off in four-week cycles. There are two dose levels, 25mg BID and 50mg BID. In part 1, the starting dose of 25mg BID(n=8) will be increased by 100% to the maximum dose of 50mg BID(n=8) if the number of patients who experience dose-limiting toxicities is less than 2 during the first cycle. In part 2, based on the relevant data from the dose escalation study, an expanded enrollment study was conducted at a safe and effective dose.Per dose group will enroll 12-24 patients. All patients will take CM082 until disease progression or unacceptable toxicity. The assessment of the safety and efficacy will be done every four weeks from 2nd-6th cycle and every 12 weeks after. Also, single/multiple dose pharmacokinetics in these patients will be studied.

Description

Inclusion Criteria:

  • Geographic atrophy involving the foveal center in the study eye.
  • Previous treatment with photodynamic therapy (PDT), external beam radiation, subfoveal focal laser photocoagulation, submacular surgery or transpupillary thermotherapy.
  • CNV due to causes other than AMD, including ocular histoplasmosis syndrome, angioid streaks, multifocal choroiditis, choroidal rupture, or pathologic myopia.
  • Any significant disease in the study eye that could compromise best-corrected visual acuity.
  • Clinically significant impaired renal or hepatic function.
  • Stroke within 12 months of the first dose or transient ischemic attack within 12 months of the first dose.
  • Symptomatic congestive heart failure, unstable angina, acute coronary syndrome, myocardial infarction or coronary artery revascularization, or arterial thrombosis within 6 months of start of study drug, inadequately controlled hypertension, or ventricular tachyarrhythmias requiring ongoing treatment.
  • QTc≥450 msec or subjects with a history of risk factors for Torsades de Pointes or other severe ECG abnormalities which are clinically relevant.
  • Trabeculectomy or aqueous shunt or valve in the study eye.
  • Use of any investigational agent or participation in any other clinical trial of an investigational agent or investigational therapy within thirty (30) days of the first dose.
  • Allergy to the ingredients of the study drug.
  • Women of childbearing age who are pregnant, breast-feeding or not using medically acceptable contraception; males who are unwilling to take adequate contraceptive measures.
  • Need to take any medicine that is a strong inhibitor or inducer of CYP3A4.
