Clinical trial: Study of Oral Ceritinib in Patients With ALK and ROS1 Activated Gastrointestinal Malignancies

Summary: The available data indicate that Ceritinib has substantial anti-tumor activity in patients with anaplastic lymphoma kinase (ALK) and ROS1 rearranged non-small cell lung cancer (NSCLC). This trial will investigate the potential of Ceritinib in patients with advanced gastrointestinal malignancies with ALK and ROA1 rearrangement, and for whom there is no available therapeutic option.

Detailed description: This is a single-arm, open-label, multicenter, phase II study of ceritinib in adult patients with ALK- and ROS1 activated colorectal, cholangiocarcinoma, pancreatic, hepatic, gastric, or esophageal adenocarcinoma. An estimated 500 patients will be screened for ALK and ROS1 by fluorescence in situ hybridization (FISH) and immunohistochemistry (IHC) per institutional standard of care (SOC), and/or ALK/ROS1 by next-generation sequencing (NGS). At least 30 identified patients will be treated with ceritinib per protocol. Treatment with ceritinib will continue until patient experiences unacceptable toxicity that precludes further treatment, discontinues treatment at the discretion of the investigator or patient, starts a new anticancer therapy and/or dies.
  Male and female patients aged 18 or over that have colorectal adenocarcinoma, cholangiocarcinoma, pancreatic, hepatocellular, gastric or esophageal adenocarcinoma that contain an activated ALK gene due to rearrangement, mutation, amplification, translocation or other mechanisms. Patients must have been pretreated with cytotoxic chemotherapy.

Eligibility: Inclusion Criteria:
  1. Histologically or cytologically confirmed diagnosis of inoperable colorectal adenocarcinoma, pancreatic, hepatocellular, cholangiocarcinoma, small bowel, gastric or esophageal adenocarcinoma that carries an activated ALK or ROS1 pathway
  2. Age 18 years or older at the time of informed consent.
  3. Patients must have received at least 1 line of cytotoxic chemotherapy
  4. Patients must have archival tissue sample available, collected either at the time of diagnosis or any time since.
  - If archival tissue is unavailable, patient must be eligible and willing to undergo a fresh tissue biopsy
  5. Patients must have recovered from all toxicities related to prior anticancer therapies to grade ≤ 2 (CTCAE v 4.03) provided that concomitant medication is given prior to initiation of treatment with LDK378, except for patients with grade 2 nausea/vomiting and/or grade 2 diarrhea despite optimal supportive therapy who will not be allowed to participate in the study. Additionally, patients with any grade of alopecia are allowed on treatment.
  6. Cohort Expansion Phase: Patient must have measurable lesions as defined by RECIST version 1.1 criteria.
  7. ECOG performance status 0-2
  8. Patients must have normal organ and marrow function as defined below: Bone marrow function defined as the following: An absolute neutrophil count ≥ (ANC) 1,500/mcl. Platelets ≥ 75,000/mcl. Hemoglobin ≥ 8 g/dl.
  9. Renal function defined as the following: Serum creatinine less than or equal to 1.5 x institutional upper limit normal (ULN). Calculated or measured creatinine clearance (CrCL) ≥ 30 mL/min
  10. Hepatic function defined as the following: Serum total bilirubin < 1.5 x ULN. AST (SGOT), ALT (SGPT), and alkaline phosphatase ≤ 3.0 x ULN. Serum albumin ≥ 2.5 g/dl. If liver involvement, AST, ALT, and alkaline phosphatase ≤ 5.0 x ULN.
  11. Serum amylase ≤ 2 x ULN and serum lipase ≤ 1 x ULN
  12. Fasting plasma glucose ≤175 mg/dL (≤9.8 mmol/L)
  13. Patient must have the following laboratory values or have the following laboratory values corrected with supplements to be within normal limits at screening:
  -  Potassium ≥ lower limit of normal (LLN)
  -  Magnesium ≥ LLN
  -  Phosphorus ≥ LLN
  -  Total calcium (corrected for serum albumin) ≥ LLN
  14. A male subject of fathering potential must use an adequate method of contraception to avoid conception throughout the study [and for up to 12 weeks after the last dose of study drug] to minimize the risk of pregnancy. If the partner is pregnant or breastfeeding, the subject must use a condom. A condom is required to be used also by vasectomized men in order to prevent delivery of the drug via seminal fluid.
  15. Women of childbearing potential (WOCBP) must be using an adequate method of contraception to avoid pregnancy throughout the study and for up to 12 weeks after the last dose of study drug to minimize the risk of pregnancy. WOCBP must have a negative serum or urine pregnancy test within 72 hours before the start of the investigational product. Highly effective contraception methods include:
  -  Total abstinence (when this is in line with the preferred and usual lifestyle of the subject. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception.
  -  Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy) or tubal ligation at least six weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment.
  -  Male sterilization (at least 6 months prior to screening) with the appropriate post-vasectomy documentation of the absence of sperm in the ejaculate. For female subjects on the study the vasectomized male partner should be the sole partner for that subject.
  -  Combination of any two of the following (a+b or a+c or b+c):
  -  Use of oral, injected or implanted hormonal methods of contraception or other forms of hormonal contraception that have comparable efficacy (failure rate < 1%), for example hormone vaginal ring or transdermal hormone contraception.
  -  Placement of an intrauterine device (IUD) or intrauterine system (IUS).
  Barrier methods of contraception: Condom or Occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/vaginal suppository.
  In case of use of oral contraception, women should have been stable on the same pill for a minimum of 3 months before taking study treatment.
  Women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g., age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks prior to screening. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential.
