the change of clinical development plan

A Phase I, open-label, multicenter dose-escalation study to assess the safety, tolerability, pharmacokinetics and preliminary anti-tumor activity of hmpl-309 in patients with advanced solid tumors

There are two stages to this study: a dose-escalation stage and a dose-expansion stage.

Dose-escalation stage: hmpl-309 administered orally once every day(QD) to patients with locally advanced or metastatic solid tumors for whom standard therapy either does not exist or has proven to be ineffective or intolerable. Dose-expansion stage: hmpl-309 administered orally 300mg once every day(QD) to patients which is only for patients with EGFR positive oesophageal carcinoma.

Inclusion Criteria:

• Histopathology confirmed solid tumors
• Failed to standard treatment or no standard treatments for uncontrolled, recurrent and/or metastatic advance tumor (whatever previous surgery conditions)

Dose-escalation stage:

<300mg/day cohort no requiremnet for pathological pattern >300mg/day cohort required NCSLC, head and net squamous carcinoma, or oesophageal carcinoma Dose-expansion stage required oesophageal carcinoma

• significant cardiovascular disease, including II-IV atrioventricular block, acute myocardial infarction within 6 months, significant angina or Coronary artery bypass graft
• Known existing interstitial lung disease
• Female patients who are pregnant or feeding, or childbearing potential patient with pregnant testing positive
