Patients with terminal stage of metastatic non-small cell lung cancer, metastatic triple negative breast cancer, or advanced or metastatic pancreatic adenocarcinoma resisting to standard therapies.

This is a multi-site, single arm, Phase II study designed to explore the efficacy of OMT-111 in patients with terminal stage solid tumors resistant to standard therapies.

Subjects who voluntarily provide written consent to participate in this study undergo screening tests within 4 weeks prior to the first dose of investigational product. Those who meet the inclusion/exclusion criteria are enrolled in the study.

1 cycle consists of 4 weeks (28 days). Each week consists of 5 days of treatment and 2 days of treatment-free interval (20 days of treatment and 8 days of treatment-free interval per cycle in total). This study is planned to enroll approximately 76 subjects including 42 subjects with lung cancer, 22 subjects with breast cancer, and 12 subjects with pancreatic cancer. Treatment will be provided for 12 cycles (48 weeks). During the study, tests and procedures to evaluate the efficacy and safety will be carried out according to the planned schedule.

Inclusion Criteria:

• Breast Cancer

  1. Female at least 18 years old or older at the time of informed consent
  2. Histologically or cytologically confirmed triple negative ductal adenocarcinoma of breast
  3. Patients who have visceral metastatic lesions not amenable by resection or radiotherapy (e.g., multiple visceral lesions)
  4. ECOG PS (Eastern Cooperative Oncology Group Performance Status): 0-2
  5. Patients with a life expectancy ≥ 12 weeks as judged by the investigator
  6. At least one measurable lesion or evaluable lesion defined by the Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1

• Pancreatic Cancer

  1. Male or female at least 18 years old or older at the time of informed consent

  5. Patients with a life expectancy ≥ 12 weeks as judged by the investigator
  6. At least one measurable lesion or evaluable lesion defined by the Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1

• Lung Cancer

  1. Male or female at least 18 years old or older at the time of informed consent
