Brief Summary

Brief Summary:

The purpose of this clinical trial is to evaluate the safety, tolerability, preliminary efficacy, and immunogenicity of EVM14 administered intramuscularly (IM) alone and in combination with pembrolizumab in patients with selected solid tumors.

Detailed Description

EVM14C101 study is a First in Human(FIH), open-label, multiregional, multicenter study conducted in 2 Phases: Phase I and Phase IIa. In Phase I, EVM14 will be administered intramuscularly(IM) as a monotherapy (Mono Cohort) and in combination with pembrolizumab (Combo Cohort) in patients with solid tumors to assess the safety and tolerability, immunogenicity, preliminary efficacy of EVM14 as monotherapy and in combination with pembrolizumab. Based on the safety and immunogenicity data of Phase I, dose of EVM14 will be selected for the Phase IIa. In Phase IIa, the safety and tolerability, preliminary efficacy, and immunogenicity of EVM14 in combination with pembrolizumab will be further assessed in patients with solid tumors.

Inclusion Criteria
  1. Selected types of solid tumor that are pathologically confirmed unresectable advanced, recurrent, or metastatic.
  2. Patients with at least 1 evaluable lesion assessed by Investigators within 28 days prior to the first dose of study treatment as defined per RECIST v1.1.

  4. Life expectancy ≥ 3 months.
  5. Patients must have adequate organ function.

Exclusion Criteria
  1. Has disease that is suitable for local treatment administered with curative intent.

  3. Histologically/cytologically confirmed nasopharynx cancer. Has non-squamous histology NSCLC. If small cell elements are present, the patient is ineligible.
  4. Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis.
  5. Has a diagnosis of immunodeficiency.
  6. Use of systemic corticosteroid (> 10 mg/day prednisone or equivalent) or other immunosuppressive medication within 14 days before the first dose of study treatment.
  7. Has active autoimmune disease that has required systemic treatment in past 2 years or history of autoimmune disease that has possibility of relapse or at risk of having these conditions.
  8. Poorly controlled co-morbidity, including but not limited to poorly controlled hypertension (systolic blood pressure ≥ 160 mmHg and/or diastolic blood pressure ≥ 100 mmHg) and poorly controlled type 2 diabetes, or other serious conditions requiring systemic treatment. Active gastric or duodenal ulcer.
  9. Cerebrovascular events (stroke, transient ischemic attack, etc.) within 6 months prior to the first dose of study treatment.
  10. QTcF interval male > 450 msec; female > 470 msec Or serious cardiovascular disease within 6 months prior to the first dose of study treatment
  11. The left ventricular ejection fraction (LVEF) < 50% during the screening period.
  12. History of Stevens-Johnson syndrome or toxic epidermal necrolysis syndrome.
  13. Patients known to be human immunodeficiency virus (HIV)-positive or have acquired immune deficiency syndrome (AIDS).
