Patient case: 50-year-old male with prostate cancer; genetic feature: ATM deletion

Clinical trial: Ceritinib in Mutation and Oncogene Directed Therapy in Thyroid Cancer

Summary: This is an, open-label, protocol designed to evaluate the activity of targeted therapy in anaplastic/undifferentiated thyroid cancer. Arm A will evaluate ATC/UTC with mutations or rearrangements detected in the ALK gene.
  There is no effective treatment for anaplastic thyroid cancer in the locally recurrent or metastatic setting. Ceritinib will be administered to the patient until disease progression by RECIST 1.1, unacceptable toxicity, withdrawal of consent, or discontinuation of the trial for any other reason.
  The primary focus of this arm of the protocol is identifying ceritinib's activity in anaplastic or undifferentiated thyroid cancer patients. Those patients with mutations identified in their ALK gene by sequencing their tumor samples, or with the established ALK abnormalities will be treated with ALK-inhibitors. These include the Ventana assay and Vysis FISH probe, and patients with tumors positive by this assay will also be considered eligible for therapy on the trial.
  Therapeutic Portion:
  ARM A: ALK Abnormality IND Ceritinib 750 mg orally daily on Day 1 Continue q4 weeks x 2 cycles
  Primary Endpoint: The development of progression; new recurrence or distant metastasis, as well as enlargement of an existing metastasis on radiographic imaging.
  Secondary Endpoints:
  1. Overall response rate for patients treated with ceritinib as part of the study.
  2. Death of study participant due to any cause.

Detailed description: This is an, open-label, protocol designed to evaluate the activity of targeted therapy in anaplastic/undifferentiated thyroid cancer. Arm A will evaluate ATC/UTC with mutations or rearrangements detected in the ALK gene.
  There is no effective treatment for anaplastic thyroid cancer in the locally recurrent or metastatic setting. Ceritinib will be administered to the patient until disease progression by RECIST 1.1, unacceptable toxicity, withdrawal of consent, or discontinuation of the trial for any other reason.
  The primary focus of this arm of the protocol is identifying ceritinib's activity in anaplastic or undifferentiated thyroid cancer patients. Those patients with mutations identified in their ALK gene by sequencing their tumor samples, or with the established ALK abnormalities will be treated with ALK-inhibitors. These include the Ventana assay and Vysis FISH probe, and patients with tumors positive by this assay will also be considered eligible for therapy on the trial.
  The goal of this multi-center, multi-arm trial is to measure the impact of treating metastatic anaplastic thyroid cancer patients with targeted therapy selected for these patients due the presence of a genetic mutation or other aberration. This trial will serve as a framework by which new biomarker-drug combinations can be identified and added as new arms.
  Therapeutic Portion:
  ARM A: ALK Abnormality IND Ceritinib 750 mg orally daily on Day 1 Continue q4 weeks x 2 cycles
  Primary Endpoint: The development of progression; new recurrence or distant metastasis, as well as enlargement of an existing metastasis on radiographic imaging. CT scans of the neck, chest, abdomen and pelvis will be performed at baseline and every two cycles (cycles are 28 days long) according to standard of care. Other imaging of these areas such as PET/MRI will be allowed if CT cannot be performed. MRI of the brain will be performed at baseline and as clinically indicated. Wherever it can be safely given, radiographic contrast agents should be given for the imaging studies.
  Secondary Endpoints:
  1. Overall response rate for patients treated with ceritinib as part of the study.
  2. Death of study participant due to any cause.

Eligibility: Inclusion Criteria:
  1. Histologically or cytologically confirmed diagnosis of anaplastic thyroid cancer or undifferentiated thyroid cancer that demonstrates mutation in the ALK gene as assessed by sequencing of the tumor specimen for Arm A. Other ALK abnormalities as detected by the approved FISH test (Abbott Molecular Inc), using Vysis breakapart probes (defined as 15% or more positive tumor cells); or the Ventana IHC test will also be seen as evidence of ALK abnormality and meeting eligibility requirement.

  10. Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive hCG laboratory test.
  11. Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during dosing and agree to continue for 3 months after the last dose of study treatment. 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):
  1. 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.
  2. Placement of an intrauterine device (IUD) or intrauterine system (IUS).
  3. 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.
  12. Sexually active males unless they agree to use a condom during intercourse while taking drug and agree to continue for 3 months after the last dose of study treatment. Male patients for 3 months should not father a child in this period. A condom is required to be used also by vasectomized men in order to prevent delivery of the drug via seminal fluid.
