Patient case: 64-year-old male with gastric cancer; genetic feature: ERBB2 amplification

Clinical trial: A Phase I-II Study of HM781-36B Combined With Paclitaxel and Trastuzumab in HER-2 Positive Advanced Gastric Cancer

Summary: [Phase I] The main objective of this study is to evaluate the safety, tolerability and determine the Recommended Dose (RD) of HM781-36B(Poziotinib)combined with Paclitaxel and Trastuzumab
  [Phase II] The main objective of this study is to evaluate anticancer activity through determination of response rate of HM781-36B(Poziotinib)combined with Paclitaxel and Trastuzumab in patients with HER-2 positive advanced gastric cancer

Detailed description: Besides the main objectives, there are other objectives as follows:
  [Phase I]
  1. To assess the pharmacokinetic profile of HM781-36B(Poziotinib) combined with Paclitaxel and Trastuzumab
  2. To evaluate anticancer activity of HM781-36B(Poziotinib) combined with Paclitaxel and Trastuzumab in patients with HER-2 positive advanced gastric cancer
  3. To evaluate PFS(Progression-Free Survival), TTP (Time To Tumor Progression), and DOR (Duration of Overall Response)
  [Phase II]
  1. To assess the safety, tolerability of HM781-36B(Poziotinib) combined with Paclitaxel and Trastuzumab
  2. To evaluate tumor response through determination of disease control rate , PFS(Progression-Free Survival), TTP (Time To Tumor Progression), and DOR (Duration of Overall Response)

Eligibility: Inclusion Criteria:

  Exclusion Criteria:
  1. Patients with a history of hypersensitivity to Trastuzumab and who have been treated with medicine including Cremophor EL
  2. Patients who have a current active malignancy other than gastric adenocarcinoma (with exception of non-melanoma skin cancer or cervical cancer in situ)
  3. Patients who have previously received taxane-based chemotherapy
  4. The presence of central nervous system metastases
  5. Patients who have a blood tumor such as leukemia, or who had previously received, or are planning to receive, the bone marrow transplant
  6. Patients with uncontrolled infection
  7. Patients who have GI malabsorption or difficulty taking oral medication
  8. Patients with following diseases are excluded:
  9. Patients with psychiatric or congenital disorder which can affect adherence or make hard to follow the requirements of the protocol
