ProAgio In Previously Treated Advanced Pancreatic Cancer And Other Solid Tumor Malignancies

Study Overview

ProAgio in Previously Treated Advanced Pancreatic Cancer and Other Solid Tumor Malignancies

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.

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. Patients will also be offered optional co-administration of gemcitabine (Gem). The expansion cohort will contain two arms: A) Biopsy Arm (8 participants), and B) Standard Arm (8 participants). Tumor biopsies performed pre- and post- (on Cycle 2 Day 2-3) ProAgio treatment are optional for participants enrolled in the Standard Arm, but mandatory for participants enrolled in the Biopsy Arm.

Primary Outcome Measures	Measure Description	Time Frame
Determine Recommended Phase 2 Dose (RP2D)	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.	3 Years

Secondary Outcome Measures	Measure Description	Time Frame
Safety and Tolerability of ProAgio	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.	3 Years
Evaluate the Maximum Plasma Concentration of ProAgio	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 Years
Evaluate the area under the curve of ProAgio	Statistical analysis of study data will calculate the area under the plasma concentration curve for each study subject that received ProAgio.	3 Years
Evaluate the Serum half-life of ProAgio	ProAgio Serum half-life will be determined using standard statistical calculations. .	3 Years
Evaluate the volume of distribution of ProAgio	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.	3 Years
Rate of study drug elimination in research participants	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.	3 Years
Objective Response Rate (ORR)	Make a preliminary assessment of anti-tumor activity by measuring objective response rate (ORR),	3 Years
Disease control rate (DCR).	Make a preliminary assessment of anti-tumor activity by measuring disease control rate at 18 weeks (DCR).	At 18 Weeks
Assess serum tumor marker CA19-9 or appropriate tumor specific marker.	Make a preliminary assessment of anti-tumor activity by measuring change in relevant serum tumor marker CA19-9 appropriate tumor specific marker.	Day 1 of each treatment cycle and 30 days after the last dose of study therapy.

Accepts Healthy Volunteers:

Histologic or cytologic diagnosis of a solid tumor malignancy for which no curative therapy exists.
Individuals must have evaluable disease, either by clinical exam, biochemical markers (including but not limited to CA 19-9 serum tumor marker for pancreatobiliary cancer, or other appropriate tumor marker in other tumor types), and/or radiographic studies.

All individuals must have advanced or recurrent disease and have received at least one prior systemic treatment. Specifically:

Individuals with metastatic, locally advanced/unresectable, or borderline resectable pancreatic cancer at diagnosis, must have received at least one prior systemic treatment and still be considered ineligible for potentially curative resection.

Individuals in the Biopsy Arm of the expansion cohort must have disease amenable to safe biopsy and willingness to undergo the procedure.
All individuals must be more than 14 days removed from most recent standard of care or experimental drug treatment for their tumor.
Age ≥18 years. Because no dosing or adverse event data are currently available on the use of ProAgio in individuals <18 years of age, children are excluded from this study.
ECOG performance status ≤ 2 (Karnofsky ≥>60%).

Individuals of child-bearing potential (IOCBP) and individuals able to father a child men must agree to use an effective method of contraception as follows:
IOCBP must agree to use an effective method of contraception (barrier, surgical sterilization, abstinence) prior to study entry, for the duration of study participation, and for at least 6 months after the last dose of study drug(s).
Individuals able to father a child must agree to use an effective method of contraception (barrier, surgical sterilization, abstinence) for the duration of the study treatment and up to 6 months after the last dose of the study drug(s). We also will recommend individuals able to father a child with IOCBP partners to ask them to be on an effective birth control (hormonal, intrauterine device [(IUD)], surgical sterilization.
Ability of individual to understand and the willingness to sign a written informed consent document.

Diagnosis of primary malignant CNS tumor.
Individuals 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.

Pregnant or nursing individuals 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.
Individuals with leptomeningeal disease or with CNS metastases that are untreated, have required steroid treatment within the last 4 weeks, or anti-convulsant therapy in the last 14 days.
