Arm Intervention/treatment
Experimental: HPN536-2001 - Part 1 (Dose Escalation)
HPN536 is IV administered once weekly for about 1 hour. Doses will vary between cohorts as MTD is being determined.
 Biological: HPN536
Dose escalation: HPN536 is a tri-specific recombinant protein construct (Tri-specific T Cell Activating Construct [TriTAC®]) containing 3 humanized antibody derived binding domains
Experimental: HPN536-2001 - Part 2 (Dose Expansion)
HPN536 is IV administered once weekly for about 1 hour at the recommended phase 2 dose established in Part 1
 Biological: HPN536
Dose expansion: HPN536 is a tri-specific recombinant protein construct (Tri-specific T Cell Activating Construct [TriTAC®]) containing 3 humanized antibody derived binding domains


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Assessment of Adverse Events by CTCAE 5.0 of HPN536 [ Time Frame: 3 years ]
    Assess safety and tolerability at increasing dose levels of HPN536 in successive cohorts of patients with of patients with epithelial ovarian cancer, fallopian tube cancer, primary peritoneal cancer, pancreatic adenocarcinoma, or mesothelioma (pleural and primary peritoneal) by adverse events (CTCAE v5.0)

  2. Determine MTD/RP2D [ Time Frame: 2 years ]
    Estimate the maximum tolerated dose (MTD) or select the recommended Phase 2 dose (RP2D)

  3. Efficacy of HPN536 at the recommended Phase 2 dose: overall response rate (ORR) [ Time Frame: 1 year ]
    Evaluate overall response rate (ORR) as assessed by RECIST

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

  1. One of the following progressive advanced or metastatic cancers:

    1. Epithelial ovarian, fallopian tube, or primary peritoneal cancer that is platinum refractory or platinum resistant
    2. Pancreatic adenocarcinoma that is locally advanced, and now with progressive disease on or after front-line treatment
    3. Malignant mesothelioma with epithelioid histology, pleural or peritoneal
  2. For Part 2 only - Measurable disease according to RECIST v1.1 for patients with epithelial ovarian, fallopian tube, or primary peritoneal cancer, pancreatic adenocarcinoma, and peritoneal mesothelioma, and mRECIST v1.1 for patients with pleural mesothelioma
  3. Available archival tissue sample, or fresh biopsy tissue sample must be obtained prior to enrollment. For Part 2 only- a fresh biopsy tissue sample is required.

  4. Adequate bone marrow function, including:

    1. Absolute neutrophil count (ANC) ≥1500/mm3 or ≥1.5 x 109/L
    2. Platelets ≥100,000/mm3 or ≥100 x 109/L
    3. Hemoglobin (Hgb) ≥9 g/dL
  5. Adequate renal function, including estimated creatinine clearance ≥30 mL/min

  6. Adequate liver function, including:

    1. Total serum bilirubin ≤1.5 x upper limit of normal (ULN) unless the patient has documented Gilbert syndrome in which case the maximum total serum bilirubin should be <5 mg/dL
    2. Aspartate and alanine transaminase (AST and ALT) ≤2.5 x ULN or AST/ALT ≤5 x ULN for patients with liver metastases
  7. Serum albumin ≥30 mg/mL

Key Exclusion Criteria:

  1. Brain metastases unless previously treated. Patients with previously treated brain metastases may participate provided they are clinically stable for at least 4 weeks prior to study entry, and have no evidence of new or enlarging brain metastases
  2. Evidence of retroperitoneal fibrosis, mesothelial surface (pleura, pericardium, peritoneum) thickening of ≥4 mm; significant or increasing pleural/pericardial effusions, ascites or pericarditis at baseline deemed unrelated to the underlying malignancy basedon computed tomography (CT), magnetic resonance imaging (MRI), or echocardiogram (ECHO); or prior history of pleurodesis, retroperitoneal fibrosis or mediastinal fibrosis.
  3. Previous Grade 3/4 infusion or hypersensitivity reaction (not immunotoxicity) to treatment with another monoclonal antibody.
  4. For patients with tumor types other than pleural mesothelioma: Ascites requiring >1 paracentesis for therapeutic purposes (i.e., not for diagnosis) within 1 month prior to Cycle 1 Day 1.
