In subjects harbouring an activating oncogenic driver mutation, after progression on one or more SOC mutation-targeting TKI, per local SOC guidelines, or for whom no SOC mutation-targeting TKI is available. TKI therapy need not be the most recent prior therapy. Subjects harbouring an activating EGFR mutation are not eligible;

    • Diagnosed or suspected congenital long QT syndrome;
    • Any history of clinically significant ventricular arrhythmias (such as ventricular tachycardia, ventricular fibrillation, or Torsades de pointes);
    • Prolonged QTc interval on electrocardiogram (ECG); QTc must be less than CTCAEv5.0 Grade 2 (≤480 msec) using Fridericia's or Bazett's correction formula with a manual reading by the investigator if required. The ECG may be repeated for evaluation of eligibility after management of correctable causes for observed QTc prolongation;
    • Any history of second- or third-degree heart block;
    • Heart rate <45 beats per minute on ECG in the presence of clinical symptoms (e.g., hypotension, evidence of hypoperfusion);
  • Severely impaired (defined as Child-Pugh Class C) hepatic dysfunction;

Exception would be effectively treated past history of non-melanoma skin cancer or in-situ cervical cancer with no evidence of active disease. Patients with a history of other malignancies are eligible if they have been continuously disease free for at least 2 years after definitive primary treatment;
  • Other severe acute or chronic medical condition that may increase the risk associated with study participation or study drug administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the subject inappropriate for entry into this study;
  • Use of narrow therapeutic index drugs that are CYP2D6 substrates (procainamide, pimozide, and thioridazine etc.) from screening to randomization.

5. Study Description

Brief Summary
Eligible subjects will be allocated to one of four cohorts based on tumour type and presence of specific biomarker. Subjects will receive open-label Dacomitinib as tablets for oral administration on a continuous daily basis at a dose of 30 mg for one cycle. After one cycle, a toxicity assessment will be conducted. Subjects with >=G2 toxicity attributable to dacomitinib, will continue dacomitinib at 30 mg orally once daily. In subjects with <=G1 toxicity, investigator and subjects will make a shared decision for dose escalation of dacomitinib to 45 mg orally once daily or continuation of dacomitinib at 30 mg orally once daily. Subjects will then continue on therapy until disease progression, new systemic anticancer therapy instituted, intolerable toxicities, withdrawal of consent, death, or investigator decision dictated by protocol compliance, whichever occurs first.
