Brief Summary:
The study is a first-in-human, Phase I study to assess the safety of ProAgio in participants with advanced solid tumor malignancies including pancreatic cancer.

Condition or disease Intervention/treatment Phase
Advanced Pancreatic Cancer Solid Tumor Malignancies Drug: ProAgio Phase 1

Detailed Description:

Pancreatic cancer is the third leading cause of death from cancer in the United States. The median overall survival for patients with metastatic disease who are receiving the most effective combination of chemotherapy regimens remains less than 1 year.

ProAgio has been evaluated in nonclinical pharmacology, safety pharmacology, pharmacokinetic (PK), and toxicity studies. It has demonstrated efficacy at treating pancreatic cancer and prolonging survival in mice.

ProAgio is being developed for intravenous (IV) administration. All participants will receive ProAgio until disease progression, unacceptable toxicity, or withdrawal from study. Subjects in the dose escalation cohorts who will be administered ProAgio at doses ranging from 3.2 to 36.8 mg/kg.

Following the dose escalation phase, an expansion cohort of patients with advanced nonendocrine pancreatic adenocarcinoma will be administered ProAgio at the maximum tolerated dose (MTD) from the dose escalation phase. The expansion cohort will comprise 16 subjects, divided into two blocks (n=8 each) of patients who agree to have optional pre and post-treatment biopsies, and those who decline the optional biopsies.

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. Determine Recommended Phase 2 Dose (RP2D) [ Time Frame: 3 Years ]
    Following completion of the dose escalation cohort, all available data relating to the pharmacokinetics, pharmacodynamics, efficacy and safety of ProAgio will be reviewed by the study team including the Principle Investigator, clinical pharmacology collaborators and the sponsor. A single ideal dose will then be selected for further investigation in the dose escalation cohort. This ideal dose may or may not be the same as the MTD.


Secondary Outcome Measures :
  1. Safety and Tolerability of ProAgio [ Time Frame: 3 Years ]
    Toxicities will be tabulated and reported per dose level according to grade and type of toxicity experienced. This will take place during the dose escalation phase as well as during the expansion phase.

  2. Evaluate the Maximum Plasma Concentration of ProAgio [ Time Frame: 3 Years ]
    ProAgio concentrations will be measured by a validated ELISA assay modified from the assay used in non-clinical studies. This PK data will be used to mathematically describe the kinetic disposition of ProAgio in humans following the current dosing schedule.

  3. Evaluate the area under the curve of ProAgio [ Time Frame: 3 Years ]
    Statistical analysis of study data will calculate the area under the plasma concentration curve for each study subject that received ProAgio.

  4. Evaluate the Serum half-life of ProAgio [ Time Frame: 3 Years ]
    ProAgio Serum half-life will be determined using standard statistical calculations. .

  5. Evaluate the volume of distribution of ProAgio [ Time Frame: 3 Years ]
    If there are sufficient participant data available, a population PK analyses will be conducted to identify covariates that may be significantly associated with the inter-individual variability for a particular PK parameter (e.g. clearance of volume of distribution).The NCI CPP may also conduct dose-response and/or exposure-response analyses that will assess PK/PD relationships with relevant biomarkers, clinical response, and adverse event data.

  6. Rate of study drug elimination in research participants [ Time Frame: 3 Years ]
    58 study participants will have study drug concentration levels analyzed with regard to drug elimination. Results will be expressed in units of inverse time, i.e. 1/hr or 1/day.

  7. Objective Response Rate (ORR) [ Time Frame: 3 Years ]
    Make a preliminary assessment of anti-tumor activity by measuring objective response rate (ORR),

  8. Disease control rate (DCR). [ Time Frame: At 18 Weeks ]
    Make a preliminary assessment of anti-tumor activity by measuring disease control rate at 18 weeks (DCR).

  9. Assess serum tumor marker CA19-9 or appropriate tumor specific marker. [ Time Frame: Day 1 of each treatment cycle and 30 days after the last dose of study therapy. ]
    Make a preliminary assessment of anti-tumor activity by measuring change in relevant serum tumor marker CA19-9 appropriate tumor specific marker.

    • Total bilirubin <1.5 X institutional ULN
    • creatinine within normal institutional limits

  • OR

    • creatinine clearance >60 mL/min/1.73 m2 for participants with creatinine levels above institutional normal
    • Serum albumin > 2.5 mg/dl without intravenous supplementation

  • Participants must have:

    • Resting systolic blood pressure < 145 and diastolic blood pressure < 90.
    • Baseline QTcF interval of = 470 ms
    • Baseline resting heart rate > 45 beats per minute and <100 beats per minute
  • The effects of ProAgio on the developing human fetus are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation and for the 3 months following the last dosing of study drug. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately.
  • Ability of subject to understand and the willingness to sign a written informed consent document.

Exclusion Criteria:

  • Diagnosis of primary malignant CNS tumor.
  • Participants who are receiving any other investigational agents.
  • Evidence of significant, uncontrolled concomitant diseases which could affect compliance with the protocol or interpretation of results, including but not limited to significant pulmonary disease other than that related to the primary cancer, uncontrolled diabetes mellitus, unstable angina, significant cardiovascular disease (such as New York Heart Association Class III or IV cardiac disease) and/or psychiatric illness/social situations within 12 weeks that would limit compliance with study requirements.
  • Participants with known diagnosis of a chronic neurologic disorders (such as multiple sclerosis, Huntington's disease, Parkinson's disease, or uncontrolled epilepsy) which causes motor disturbance, visual disturbance or seizure and could confound assessment of neurologic toxicity caused by the study drug.
  • Pregnant or nursing women are excluded from this study because ProAgio is an agent with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with ProAgio, breastfeeding should be discontinued if the mother is treated with ProAgio.

  • Participants with active or uncontrolled infections are excluded.
  • Participants with HIV and detectable viral load are excluded. Patents on appropriate highly active anti-retroviral therapy with undetectable viral load are eligible.
  • Participants with a history of Hepatitis B or C are excluded unless there is documented evidence of effective treatment and/or cure with undetectable viral load.
  • Participants with recent (within < 28 days) thromboembolic disease including but not limited to acute coronary syndrome, stroke, or transient ischemic attack, recent deep vein thrombosis or pulmonary embolism are excluded.
  • Participants with thromboembolic disease including but not limited to acute coronary syndrome, stroke, or transient ischemic attack, recent deep vein thrombosis or pulmonary embolism who have continued symptoms, or who are not on stable doses of appropriate antiplatelet / anticoagulant regimens are excluded.
