A Study of Romidepsin (Depsipeptide) in Combination With Gemcitabine in Patients With Pancreatic and Other Advanced Solid Tumors

Phase 1

Completed

• Conditions: Pancreatic Cancer
• Interventions: Drug: Romidepsin; Drug: Gemcitabine

• Registration Number: NCT00379639
• Lead Sponsor: Celgene

Brief Summary

This was a phase I dose escalation trial designed to determine the maximum tolerated dose (MTD) for the combination of romidepsin (depsipeptide) and gemcitabine. The study was originally planned as a Phase I/II; however only Phase I of the study was conducted.

Exclusion Criteria

• Prior treatment with romidepsin or gemcitabine

• Prior chemotherapy treatment within 3 weeks prior to the first day of treatment or prior treatment with an investigational agent within 4 weeks prior to the first day of treatment. Patients must have recovered from all therapy-related toxicities (Common Terminology Criteria grade ≤ 1)

• Prior radiotherapy within 4 weeks prior to the first day of treatment. Patients who have not fully recovered or whose acute toxicity related to prior radiotherapy has not returned to baseline are ineligible.

• Prior surgery within 3 weeks prior to the first day of treatment, excluding surgical biopsies and port placements

• Concomitant use of any other anti-cancer therapy

• Concomitant use of any investigational agent

• Use of any investigational agent within 4 weeks of study entry

• Any known cardiac abnormalities, including congenital long QT syndrome, QTcF interval >480 milliseconds, myocardial infarction within 12 months of study entry, coronary artery disease (CAD), congestive heart failure (CHF), evidence of cardiac ischemia at screening, known history of sustained ventricular tachycardia (VT), ventricular fibrillation (VF), Torsade de Pointes, or cardiac arrest, hypertrophic cardiomegaly or restrictive cardiomyopathy chronic hypertension, any cardiac arrhythmia requiring anti-arrhythmic medication

• Serum potassium <3.8 mmol/L or serum magnesium <2.0 mg/dL (electrolyte abnormalities can be corrected with supplementation to meet inclusion criteria)

• Concomitant use of drugs that may cause a prolongation of the QTc

• Concomitant use of CYP3A4 inhibitors

• Clinically significant active infection

• Known infection with human immunodeficiency virus (HIV), hepatitis B, or hepatitis C

• Inadequate bone marrow or other organ function as evidenced by:

  • Hemoglobin <9 g/dL (Transfusions and/or erythropoietin are permitted.)
  • Absolute neutrophil count (ANC) ≤1.5 x 10^9 cells/L
  • Platelet count <100 x 10^9 cells/L or platelet count <75 x 10^9 cells/L if bone marrow disease involvement is documented
  • Total bilirubin >2.0 x upper limit of normal (ULN)
  • Aspartate transaminase/serum glutamic oxaloacetic transaminase (AST/SGOT) and alanine transaminase/serum glutamic pyruvic transaminase (ALT/SGPT) >2.0 x ULN or >3.0 x ULN in the presence of demonstrable liver metastases
  • Serum creatinine >2.0 x ULN

• Patients who are pregnant or breast-feeding

• Any significant medical or psychiatric condition that might prevent the patient from complying with all study procedures

Arm && Interventions

Group	Intervention	Description
Romidepsin / Gemcitabine	Gemcitabine	Participants were to receive 7, 10 or 12 mg/m\^2 of romidepsin intravenously on either Days 1, 8 and 15 (Schedule A) or Days 1 and 15 (Schedule B) of each 28-day cycle, followed by 800 or 1000 mg/m\^2 of gemcitabine. Subsequent doses of both drugs were based on treatment-related toxicities. The planned duration of study therapy was 6 cycles or until disease progression occurred. Patients who responded could continue beyond 6 cycles until disease progression or until a withdrawal criterion was met.

Primary Outcome Measures

Name	Time	Method
Number of Participants With a Dose-limiting Toxicity (DLT)	28 days	Toxicities were assessed according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), V 3.0. A DLT was one of the following, if considered at least possibly related to study treatment: Grade 4 neutropenia for ≥5 days or febrile neutropenia; Grade 4 thrombocytopenia or need for a platelet transfusion; ≥ Grade 3 nausea and/or emesis despite using optimal antiemetic therapy; ≥ Grade 3 diarrhea despite using maximal supportive therapy; Any clinically significant Grade 3 or 4 nonhematologic toxicity; Inability to administer all doses in cycle 1.
Number of Participants With Adverse Events (AEs)	From the date of first dose to 30 days after last dose (up to 236 days).	AEs were graded for severity according to the National Cancer Institute Common Terminology Criteria (NCI CTCAE), V 3.0: Grade 1: Mild; Grade 2: Moderate; Grade 3: Severe (prevents normal everyday activities); Grade 4: Life-threatening or disabling; Grade 5: Death.; A serious AE is associated with events that pose a threat to a patient's life or functioning, require hospitalization, is a congenital anomaly/birth defect or is an important medical event or condition that may jeopardize the patient and may require medical or surgical intervention to prevent one of the above outcomes.
Best Overall Response	Disease assessments were performed within 4 weeks of first dose and every 8 weeks thereafter (up to 236 days).	Disease response was determined by the Investigator according to Response Evaluation Criteria in Solid Tumors (RECIST) criteria using computed tomography or magnetic resonance imaging: Complete Response (CR): Disappearance of all target lesions; Partial Response (PR): At least a 30% decrease in the sum of the longest diameter (LD) of target lesions; Progressive Disease (PD): At least a 20% increase in the sum of the LD of target lesions or the appearance of ≥1 new lesions; Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD.
