Brief Summary

This study is an open-label, multicenter, phase Ia/Ib study. The study will evaluate the safety, tolerability and preliminary efficacy of IBI363 in subjects with advanced, relapsed or metastatic solid tumors or lymphoma, determine the maximum tolerated dose (MTD) or maximum administered dose (MAD), and thus determine the recommended phase 2 dose (RP2D).

Conditions

Solid Tumors or Lymphoma

Outcome Measures

Primary Outcomes (7)

• Number of dose-limiting toxicity (DLT)

  Incidence of dose-limiting toxicity (DLT) events

  21 days during the first 3-week cycle

• incidence of adverse events (AE), serious adverse events (SAEs), treatment-emergent AEs (TEAEs) and immune-related AEs (irAEs)

  AE is defined as an medical problem that happens during treatment with a drug or other therapy. An SAE is any untoward medical occurrence that, at any dose results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability or incapacity, is a congenital anomaly/birth defect or is an important medical event that may jeopardize the participant or may require medical or surgical intervention to prevent one of the other outcomes listed before. A TEAE will be defined as any new AE that begins, or any pre-existing condition that worsens in severity, after at least 1 dose of study treatment has been administered. irAEs will be assessed.

  up to 90 days after the last administration

• Number of participants with abnormality in vital signs

  Blood pressure, pulse, respiratory rate, and temperature will be assessed.

  up to 90 days after the last administration

• Number of participants with abnormality in hematology parameters

  Blood samples will be collected to evaluate hemoglobin, white blood cell (WBC) count, platelets and coagulation factors including international normalized ratio (INR), activated partial thromboplastin time (aPTT) and prothrombin time (PT)

  up to 90 days after the last administration

• Number of participants with abnormality in clinical chemistry parameters

  Blood samples will be collected to evaluate sodium, potassium, calcium, magnesium, chloride, glucose, creatinine, urea or blood urea nitrogen (BUN), bicarbonate, amylase, bilirubin, alkaline phosphatase, aspartate aminotransferase (AST), alanine aminotransferase (ALT), total protein, albumin, lactate dehydrogenase and lipase.

  up to 90 days after the last administration

• Number of participants with abnormality in routine urinalysis parameters

  Urine samples will be collected to evaluate specific gravity, leucocyte esterase, nitrite, blood, bilirubin, protein, glucose, ketones and urobilinogen.

  up to 90 days after the last administration

• Number of participants with abnormality in ECG parameters

  12-lead ECG will be obtained using an ECG machine. Participants will be in supine or a semi-recumbent position (about 30 degrees of elevation) and rested for approximately 2 minutes before ECGs are recorded.

  up to 90 days after the last administration

Secondary Outcomes (14)

• maximum concentration (Cmax)

  Up to 2 years

• area under the curve (AUC)

  Up to 2 years

• clearance (CL)

  Up to 2 years

• half-life (t1/2) of IBI363

  Up to 2 years

• volume of distribution (V)

  Up to 2 years
