Patient case: 64-year-old female with Lung adenocarcinoma. Genetic variant: ALK Fusion. Other conditions: Emphysema.

Clinical trial: Trial of TKF Inhibition in Unresectable Stage III/IV BRAF/NRAS WT Melanoma

Summary: This is a phase II multi-center prospective basket trial designed to test the hypothesis that targeting specific kinase fusions in metastatic melanoma with pre-specified kinase inhibitors will result in objective tumor shrinkage and durable response. The study design is a 2 stage optimal design with a sample size of N=35, with n1=11 during stage I and n2=24 during stage II. If 1 or fewer responses are observed during stage I, the trial will be stopped. If 6 or fewer responses are observed by the end of stage II, the trial will be stopped.

Detailed description: This is a phase II prospective multi-center basket trial designed to test the hypothesis that targeting specific kinase fusions in metastatic melanoma with kinase inhibitors matched to the activated kinase fusion will result in tumor response. The study design is a 2-stage optimal design. Patients will be screened for one of the eligible fusion proteins using various assays developed in a CLIA-approved laboratory (targeted next-generation sequencing of tumor tissue, fluorescence in situ hybridization and immunohistochemistry) under a separate protocol. If identified, patients will be offered enrollment in this protocol and will be treated in one of five baskets.
  The dose of INC280 at 600 mg PO BID is based on the recommended phase II dose (RP2D) by Novartis. The dose of ceritinib at 750 mg PO daily is the FDA-approved dose for ALK-rearranged NSCLC resistant to intolerant to crizotinib. For regorafenib we will dose at 160 mg PO daily (first 21 days of each 28 day cycle) which is the FDA-approved dose for both colon cancer and GIST. The dose of entrectinib at 600 mg PO QD is the RP2D based on two Phase 1 studies conducted by Ignyta.

Palliative radiotherapy for bone lesions ≤ 2 weeks prior to starting INC280 is allowed.
  -  Receipt of any anti-cancer or investigational agent within 4 weeks or ≤ 5 half-lives of the agent (whichever is longer) prior to the first dose of INC280. If previous treatment is a monoclonal antibody, then the treatment must be discontinued at least 4 weeks before the first dose of INC280.
  -  Major surgery (e.g., intra-thoracic, intra-abdominal or intra-pelvic) within 4 weeks prior (2 weeks for resection of brain metastases) to starting INC280. Video-assisted thoracic surgery (VATS) and mediastinoscopy will not be counted as major surgery and patients can be enrolled in the study ≥ 1 week after the procedure.

  -  Presence or history of carcinomatous meningitis.
  -  Known symptomatic brain metastases requiring increasing doses of steroid to manage CNS symptoms within 2 weeks prior to study entry.
  -  Patients with asymptomatic brain metastases may be enrolled at the discretion of the Sponsor as long as the patient is stable and has not required increasing dose of steroids to manage CNS symptoms for at least 2 weeks prior to study enrollment.
  -  Patients requiring seizure prophylaxis must be taking non-enzyme-inducing anti- epileptic drugs (non-EIAED). If patients were previously on EIAEDs and these have been discontinued, they must be discontinued for at least 1 weeks prior to INC280 administration. If patients require an anti-epileptic medication, then a CYP3A4 non- EIAED can be used such as levetiracetam, valproic acid, gabapentin, topiramate or lacosamide.
  -  Pregnant or nursing women, or women intending to become pregnant during the study (where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive serum hCG laboratory test). Pregnant women are excluded from this study because the study drugs are either teratogenic or have unknown teratogenicity. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother, nursing women are excluded unless they discontinue breastfeeding during the study.
  -  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 for 7 days after the last dose of INC280. 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.
  -  Combination of any two of the following (i+ii or i+iii or ii+iii):
  -  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.
  -  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 6 weeks ago. 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.
  -  Sexually active males unless:
  -  A condom is used during intercourse while taking drug and 7 days after the last dose of entrectinib. Male patients should not father a child in the 7 days after the last dose of the study treatment.
  -  Male sterilization has taken place, with appropriate post-vasectomy documentation of the absence of sperm in the ejaculate. Condom use is also required in vasectomized men in order to prevent delivery of the drug via seminal fluid.
