Phase I Trial of Combination of FOLFIRI and SOM 230

This is an interventional treatment trial for Gastrointestinal Tumor focused on measuring colon, rectum, small bowel, pancreas, gastric, esophageal, metastatic, unresectable, GI, combination therapy, dose escalation, solid tumor Read More

Inclusion Criteria:

• Histologically proven metastatic/unresectable gastrointestinal malignancies (colon, small bowel, pancreas, gastric and esophageal cancer, etc.) not amenable to curative surgical therapy, for whom FOLFIRI can be considered a standard treatment
• Have had at least 1 prior treatment for all GI tumors except for small bowel adenocarcinoma as FOLFIRI can be considered standard first line therapy for that particular tumor.
• Measurable disease as per Response Evaluation Criteria in Solid Tumors (RECIST) criteria
• ≥ 4 weeks since any major surgery, completion of radiation, or completion of all prior systemic anticancer therapy (adequately recovered from the acute toxicities of any prior therapy)
• Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2
• Adequate bone marrow function as shown by: absolute neutrophil count (ANC) ≥ 1.5 x 10^9/L, Platelets ≥ 100 x 10^9/L, hemoglobin (Hgb) > 9 g/dL
• Adequate liver function as shown by: serum bilirubin ≤ 2 x upper limit of normal (ULN), and serum transaminases activity ≤ 3 x ULN
• Adequate renal function as shown by serum creatinine ≤ 1.5 x ULN
• Fasting serum cholesterol ≤300 mg/dL OR ≤7.75 mmol/L AND fasting triglycerides ≤ 2.5 x ULN. Note: In case one or both of these thresholds are exceeded, the patient can only be included after initiation of appropriate lipid lowering medication.
• Women of childbearing potential (WOCBP) must have a negative serum pregnancy test within 14 days of the administration of the first study treatment. Women must not be lactating.
• Signed informed consent to participate in the study must be obtained from patients after they have been fully informed of the nature and potential risks by the investigator (or his/her designee) with the aid of written information

Exclusion Criteria:

• Prior treatment with irinotecan. Irinotecan with radiation will be allowed if > 4 weeks.
• Any cytotoxic chemotherapy, radiation, immunotherapy, or any investigational drug within the preceding 3 weeks of starting the study treatment
• History of liver disease, such as cirrhosis or chronic active hepatitis B and C
• History of, or current alcohol misuse/abuse within the past 12 months
• Known gallbladder or bile duct disease, ( ie infection or cholecystitis) acute or chronic pancreatitis
• Have undergone major surgery within 4 weeks prior to study enrollment
• Uncontrolled brain or leptomeningeal metastases, including patients who continue to require glucocorticoids for brain or leptomeningeal metastases. Patients who have been treated at least 4 weeks prior to enrollment, and have a computed tomography (CT) scan or magnetic resonance imaging (MRI) of brain within 4 weeks of enrollment, which shows no evidence of progression of disease in brain, are allowed to enroll.
• Patients with uncontrolled diabetes mellitus defined as hemoglobin A1c (HbA1c) >8% despite therapy or a fasting plasma glucose > 1.5 ULN. Note: At the principal investigator's discretion, non-eligible patients can be re-screened after adequate medical therapy has been instituted.
• Symptomatic cholelithiasis
• Have congestive heart failure: New York Heart Association (NYHA) Class III or IV and unstable angina
• History of syncope or family history of idiopathic sudden death
• Sustained or clinically significant cardiac arrhythmias including sustained ventricular tachycardia, ventricular fibrillation, clinically significant bradycardia, advanced heart block (Mobitz II or higher atrioventricular nodal block AV)) , patients with prolonged corrected QT interval (QTc) (longer than 470 milliseconds) or a history of acute myocardial infarction within the 6 months preceding enrollment. (The "QT interval" is the time between the start of the Q wave and the end of the T wave in the cardiac electrical cycle. The "QTc" is the QT interval corrected for heart rate.)
• Risk factors for Torsades de Pointes such as hypokalemia, hypomagnesemia, cardiac failure, clinically significant/symptomatic bradycardia, or high-grade AV block
• Concomitant disease(s) that could prolong QT such as autonomic neuropathy (caused by diabetes or Parkinson's disease), human immunodeficiency virus (HIV), cirrhosis, uncontrolled hypothyroidism or cardiac failure
• Patients found to have sustained ventricular tachycardia, ventricular fibrillation, advanced heart block (Mobitz II or higher AV nodal block) , prolonged QTc (average longer than 470 milliseconds) in the holter monitor at the screening time. (this only applies to patients in cohorts of 60 mg of SOM 230 or higher)
• Concomitant medication(s) known to prolong the QT interval (patient must be off the drug for 2 weeks to be eligible)
• Presence of active or suspected acute or chronic uncontrolled infection or with a history of immunocompromise, including a positive HIV test result
• Any severe and/or uncontrolled medical conditions or other conditions that could affect their participation in the study such as: Severely impaired lung function; Any active (acute or chronic) or uncontrolled infection/ disorders; Nonmalignant medical illnesses that are uncontrolled or whose control may be jeopardized by the treatment with the study therapy
• Known or suspected allergy or hypersensitivity to any component of FOLFIRI, somatostatin analogues or any component of the pasireotide or octreotide long acting release (LAR) formulations
• No active malignancy except for nonmelanoma skin cancer or in situ cervical cancer or treated cancer from which the patient has been continuously disease free more than 5 years
• Women pregnant or breast feeding, or women/men able to conceive and unwilling to practice an effective method of birth control. WOCBP must have a negative serum pregnancy test within 14 days prior to administration of pasireotide. Oral, implantable, or injectable contraceptives may be affected by cytochrome P450 interactions, and are therefore not considered effective for this study
• Unwilling to or unable to comply with the protocol
