Study Overview

Trial to Evaluate Safety and Tolerability of GP-2250 in Combination With Gemcitabine

This is a phase 1 first in human, dose escalation trial of GP-2250 administered in combination with gemcitabine in subjects with advanced pancreatic cancer previously treated with 5-fluorouracil-based chemotherapy. Prior radiosensitization with gemcitabine, the use of 5-fluorouracil, FOLFIRINOX or Nab-paclitaxel/gemcitabine in the neoadjuvant setting, and prior pancreaticoduodenectomy (Whipple procedure) is allowed. If prior treatment with gemcitabine was at therapeutic doses, a minimum of 3 months must have elapsed since the end of such treatment. As a precursor to 5-FU use of capecitabine-based chemotherapy is also permitted.

This trial used a Bayesian Optimal Interval (BOIN) dose escalation design of GP-2250 as a single-dose monotherapy (Cycle 1 only) followed by combination therapy with gemcitabine for Cohorts 1 through 5. Following implementation of Amendment 7 and beginning with dose Cohort 6 and all subsequent cohorts, the trial will use a 3+3 dose escalation design, and will continue as single-dose monotherapy (Cycle 1 only) followed by combination therapy with gemcitabine. Subjects will continue to receive treatment until disease progression assessed by RECIST V1.1 criteria, clinical disease progression as assessed by the Investigator, development of a dose limiting toxicity, unacceptable toxicity, subject request for withdrawal, Investigator assessment that risk outweighs benefit, or study closure by the Sponsor.

Treatment

Allocation:
Na

Interventional Model:
Single Group

Masking:
None

Arms and Interventions

Participant Group/ArmIntervention/Treatment
EXPERIMENTAL: GP-2250 Monotherapy

GP-2250 in doses of 250 mg up to 30 grams intravenously on Days -7, 1, 8, 15 (Cycle 1) and Cycle 2 and all subsequent cycles on Days 7, 8, 15 of a 28-day cycle with gemcitabine 1000 mg/m2 on Days 1, 8, 15 days of the cycle.

DRUG: GP-2250

  • GP-2250 monotherapy for pharmacokinetics and safety; GP-2250 plus gemcitabine for safety, tolerability, pharmacokinetics, and biomarker assessments
Primary Outcome MeasuresMeasure DescriptionTime Frame
Dose Limiting Toxicity (DLT)Dose Limiting Toxicity - dose at which toxicity causes cessation of dose escalations.12-24 months
Secondary Outcome MeasuresMeasure DescriptionTime Frame
Carbohydrate Antigen 19-9 (CA-19-9)A type of antigen released by pancreatic cancer cells and usually changes as disease progression or regressions occurs. Measurement of changes, if any, will be assessed in each patient.12-24 months
Effect on diseaseTo assess the preliminary efficacy of GP 2250 in combination with gemcitabine6-12 months
