Brief Summary:
This is a Phase 1b, open-label, dose escalation study to evaluate the safety, tolerability, PK, and immunogenicity of an ADG116-pembrolizumab combination regimen in patients with advanced/metastatic solid tumors. Study drug ADG116, is an anti -CTLA-4 fully human monoclonal antibody that specifically binds to human CTLA-4. Pembrolizumab is a PD-1 receptor-blocking antibody (a humanized IgG4 monoclonal antibody) which is indicated for the treatment of patients across a number of indications. The treatment strategy of using anti-PD 1 therapy combined with anti-CTLA-4 therapy is to explore the potential of combination checkpoint inhibition regimens for the enhanced antitumor efficacy results.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Patients must meet all of the following inclusion criteria to be eligible for participation in this study:

    1. ≥ 18 years of age at the time of informed consent.
    2. Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1 with no deterioration over the previous 2 weeks.
    3. Patients with advanced or metastatic solid tumors, histologically or pathologically confirmed, who have progressed after all standard therapies, or for whom no further standard therapy exists. Patients who have declined standard therapy or have no access to standard therapy may be enrolled and the reasons for lack of access need to be documented.
    4. Patients should have at least 1 measurable lesion at baseline according to the definition of RECIST v1.1. Lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions.
    5. Patients previously treated with anti-CTLA 4 checkpoint inhibitors or anti programmed cell death 1 (PD-1)/L1 will also be recruited if they meet all eligibility criteria. For anti-PD-1/L1 patients, patients must have progressed on treatment with an anti PD 1/L1 monoclonal antibody (mAb) administered either as monotherapy, or in combination with other checkpoint inhibitors or other therapies. Anti PD-1/L1 treatment progression is defined by meeting all of the following criteria:

      1. Has received at least 2 doses of an approved anti-PD-1/L1 mAb.
      2. Has demonstrated disease progression (PD) after PD-1/L1 as defined by RECIST v1.1. The initial evidence of PD is to be confirmed by a second assessment no less than 4 weeks from the date of the first documented PD, in the absence of rapid clinical progression.
      3. Progressive disease has been documented within 12 weeks from the last dose of anti-PD-1/L1 mAb.

      i. Progressive disease is determined according to iRECIST. ii. This determination is made by the Investigator. Once PD is confirmed, the initial date of PD documentation will be considered the date of disease progression.

    6. Adequate hematologic function, defined by the following:

      1. Absolute neutrophil count (ANC) ≥ 1.5 × 109/L, without the use of granulocyte colony stimulating factor such as filgrastim within 2 weeks prior to study treatment.
      2. Platelet count ≥ 100 × 109/L without transfusion within 2 weeks (≤ 14 days) prior to study treatment.
      3. Hemoglobin ≥ 9 g/dL without transfusion or erythropoietin within 2 weeks (≤ 14 days) prior to study treatment.
    7. Aspartate transaminase (AST) and alanine aminotransferase (ALT) ≤ 2.5 × upper limit of normal (ULN), and total bilirubin ≤ 1.5 × ULN. Exceptions: Patients who have serum bilirubin increases due to documented underlying Gilbert's Syndrome or familial benign unconjugated hyperbilirubinemia may be enrolled. Patients with known liver metastases or patients with hepatocellular carcinoma may be enrolled with AST, ALT, and/or total bilirubin ≤ 5 × the ULN.
    8. Adequate renal function defined by either a creatinine clearance ≥ 45 mL/min (by Cockcroft-Gault formula) or serum creatinine (SCr) ≤ 1.5 × ULN
    9. Coagulation tests, defined by the following:

      1. Activated partial thromboplastin time (aPTT) ≤ 1.5 × ULN.
      2. International normalized ratio (INR) ≤ 1.5 × ULN. Exception: INR 2 to ≤ 3 × ULN is acceptable for patients on Warfarin anticoagulation.
    10. Left ventricular ejection fraction (LVEF) ≥ 50% measured by multiple-gated acquisition (MUGA) or echocardiogram (ECHO.).
    11. Previous antitumor therapy (including endocrine, chemoradiotherapy/ radiotherapy, targeted therapy, or immunotherapy) that has ended at least 4 weeks prior to administration of ADG116. Focal radiation therapy for symptom relief must have been completed at least 2 weeks prior to the first dose of ADG116. Participants must have recovered from all radiation-related toxicities, not require corticosteroids, and not have had radiation pneumonitis. A 1-week washout is permitted for palliative radiation (≤ 2 weeks of radiotherapy) to non-CNS disease. Exception: hormonal therapy for prostate cancer is allowed (Section 6.7).
    12. Previous AEs have been improved to baseline or Grade ≤ 1 NCI CTCAE v5.0 (except for patients with alopecia). Participants with Grade ≤ 2 neuropathy may be eligible. Participants with endocrine-related AEs Grade ≤ 2 requiring treatment or hormone replacement may be eligible.

Exclusion Criteria:
