A Phase II Study of FOLFOX Combined With Nab-Paclitaxel (FOLFOX-A) in the Treatment of Metastatic or Advanced Unresectable Gastric, Gastro-Esophageal Junction Adenocarcinoma. Big Ten Cancer Research Consortium: BTCRC-GI15-015
This is an open label, single-arm phase II, multi-institutional trial to evaluate the efficacy and safety of the combination of nab-paclitaxel and FOLFOX (FOLFOX-A) as first line therapy for patients diagnosed with histologically-confirmed advanced gastric/GEJ adenocarcinoma.
All patients will receive FOLFOX-A on days 1 and 15 of each cycle (1 cycle = 28 days). Nab-paclitaxel will be given at a dose of 150 mg/m2 IV over 30 minutes, followed by oxaliplatin IV 85 mg/m2 and leucovorin IV 400 mg/m2 over 2 hours, and 5-FU as a continuous IV infusion over Day 1 and Day 2 (for a total dose of 2400mg/m2 over 46-48 hours.). Radiographic assessment will be performed at baseline and every other cycle (starting with Cycle 3) to evaluate response to treatment by RECIST Version 1.1 guidelines. Patients may continue to receive treatment until disease progression or unacceptable toxicity.
Inclusion Criteria:
Subject must meet all of the following applicable inclusion criteria to participate in this study:
Written informed consent and HIPAA authorization for release of personal health information. NOTE: HIPAA authorization may be included in the informed consent or obtained separately.
Age ≥ 18 years at the time of consent.
ECOG Performance Status of 0-1 within 28 days prior to registration.
Histologically-confirmed advanced or metastatic unresectable gastric carcinoma, or adenocarcinoma of the gastroesophageal junction.
Prior neoadjuvant or adjuvant chemotherapy, hormonal therapy, immunotherapy, radiation or chemoradiotherapy must have been completed at least 6 months prior to documented recurrence or metastatic disease. NOTE: patients must not have received previous systemic treatment for metastatic disease.
Evaluable disease according to RECIST v1.1 for solid tumors, within 28 days prior to registration.
Demonstrate adequate organ function as described below; all screening labs to be obtained within 28 days prior to registration.
Females of child-bearing potential (defined as a sexually mature woman who (1) has not undergone hysterectomy [the surgical removal of the uterus] or bilateral oophorectomy [the surgical removal of both ovaries] or (2) has not been naturally postmenopausal for at least 24 consecutive months [i.e., has had menses at any time during the preceding 24 consecutive months]) must:
Either commit to true abstinence* from heterosexual contact (which must be reviewed on a monthly basis), or agree to use and be able to comply with effective contraception without interruption 28 days prior to starting investigational product (IP), and while on study medication (including dose interruptions) and for 30 days following the last dose of IP; and
Have a negative serum pregnancy test (β -hCG) result at screening and agree to ongoing pregnancy testing prior to each treatment and after the end of study therapy. This applies even if the subject practices true abstinence* from heterosexual contact.
Male subjects must practice true abstinence* or agree to use a condom during sexual contact with a pregnant female or a female of childbearing potential while participating in the study, during dose interruptions and for 6 months following IP discontinuation, even if he has undergone a successful vasectomy.
Exclusion Criteria
Subjects meeting any of the criteria below may not participate in the study:
Her-2 positive gastric tumor.
Treatment with any investigational products within 28 days prior to study registration.
Preexisting peripheral neuropathy is not allowed from any cause.
Known history of Human Immunodeficiency Virus (HIV) or Hepatitis C (baseline testing is not required).
Patients with active sepsis or pneumonitis
Known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Subjects with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging for at least four weeks prior to trial registration and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not using steroids for at least 7 days prior to trial registration.
Known hypersensitivity to fluorouracil (5-FU), oxaliplatin, or other platinum agents.
Known hypersensitivity to nab-paclitaxel or any of its excipients.
History of slowly progressive dyspnea and unproductive cough, or pulmonary conditions such as sarcoidosis, silicosis, idiopathic pulmonary fibrosis, hypersensitivity pneumonitis or multiple allergies. See section 6.5.1.
Has known dihydropyrimidine dehydrogenase deficiency (DPD) deficiency (testing not required)
Ongoing or active infection requiring systemic treatment (must be afebrile for ≥ 48 hours prior to study registration)
Uncontrolled intercurrent illness including, but not limited to any of the following:
Pregnant or breastfeeding (NOTE: breast milk cannot be stored for future use while the mother is being treated on study).
Known additional malignancy within the past 3 years. Exceptions include treated localized basal cell or squamous cell carcinoma of the skin, in situ cervical or vulvar carcinoma that has undergone potentially curative therapy, superficial bladder tumors (Ta, Tis & T1), ductal carcinoma in situ (DCIS) of the breast and low grade prostate cancer (Gleason sore 6). Any cancer curatively treated > 3 years prior to registration with no clinical evidence of recurrence is permitted.
Psychiatric illness/social situations that would limit compliance with study requirements.
Any other illness or condition that the treating investigator feels would interfere with study compliance or would compromise the patient's safety or study endpoints
