Full Title of Study: “A Phase II Trial of LDK378 as the First or Second-line Therapy in ROS1 and /or ALK Over-expressed Advanced Intrahepatic or Hilar Cholangiocarcinoma”
- Study Type: Interventional
- Study Design
- Intervention Model: Single Group Assignment
- Primary Purpose: Treatment
- Masking: None (Open Label)
- Study Primary Completion Date: January 2018
Sample size: LDK378 will be considered as an active agent and deserved for further development. Considering 10% dropout rate, total 34 patients will be included.
Step 1: LDK378 in suitable patients:
Collect tumor tissue for immunohistochemistry staining to confirm the status of ROS1 or ALK expression. If the patient fits all criteria, LDK378 750 mg ( p.o.) daily, with 3 week as a treatment cycle.
Step 2: Evaluation of tumor response according to RECIST 1.1 version
1. Evaluation will be done at baseline and every 6 weeks
2. Evaluation will be performed with CT or MRI and the response is defined as follows:
- Complete response – the disappearance of all target lesions.
- Partial response – at least a 30% decrease in the sum of the longest diameter of target lesions compared to the baseline sum longest diameter.
- Progressive disease – at least a 20% increase in the sum of the longest diameter of target lesions compared to the smallest sum longest diameter recorded since the treatment started or the appearance of one, or more new lesions, or reappearance of any lesion that had disappeared, or clear worsening of any assessable disease, or appearance of any new lesion or site.
- Stable disease – neither sufficient shrinkage to qualify for partial response nor sufficient increase to qualify for progressive disease, compared to the smallest sum longest diameter since the treatment started
- Drug: LDK378
- LDK378 750 mg ( p.o.) daily, with 3 week as a treatment cycle.

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.

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.
