About
The purpose of this study is to find out if a new drug, LDE225, is safe and has beneficial effects when combined with paclitaxel in women with platinum resistant ovarian cancer. Platinum resistant ovarian cancer refers to recurrent ovarian cancer that has undergone chemotherapy inclusive of a platinum compound (e.g. carboplatin or cisplatin).
Full description
Ovarian cancer remains the deadliest gynecologic cancer with a fairly low long-term cure rate. LDE225 is a new type of drug that inhibits or blocks a pathway responsible for cancer cell growth. LDE225 is an investigational drug that has been used either solely or in combination with chemotherapy in other types of cancer but not in ovarian cancer. Research evidence suggests that by combining LDE225 and paclitaxel together, ovarian cancer cells may become more responsive to treatment.

Inclusion criteria
Recurrent epithelial ovarian, fallopian tube or primary peritoneal carcinoma Histologic confirmation of the original primary tumor is required
Papillary serous, endometrioid, clear cell, undifferentiated and mixed histologies
Platinum resistant or refractory disease as per standard clinical and Gynecologic Oncology Group definition. Patients have had a treatment-free interval of less than 6 months from last platinum-based treatment to recurrence or progression during platinum based therapy
Patients must have received at least one-prior platinum based chemotherapy regimen, to include cisplatin, carboplatin or other organoplatinum compound, for treatment of primary or recurrent ovarian, fallopian tube or primary peritoneal cancer
Patients must have received a taxane as part of their prior treatment
Measurable disease is required. By definition, measurable disease is at least one lesion that can be accurately measured in at least one dimension with the longest dimension to be recorded. Each lesion must be ≥ 20 mm when measured by conventional techniques, including palpation, plain x-ray, CT, MRI or ≥ 10 mm when measured by spiral CT imaging
Patients must have one target lesion to be utilized in order to assess response per RECIST criteria
ECOG Performance statuses of 0, 1, or 2
Adequate organ function as evidenced by:
Signed informed consent.
Female patients of any ethnic group. Female patients must be surgically sterile, postmenopausal (no menses for at least one year), or using medically approved method of contraception (excluding rhythm, withdraw or abstinence)
Age greater than or equal to 19
Recovery from effects of any recent surgery, chemotherapy and/or radiation
Exclusion criteria
Patients with pathology demonstrating mucinous, carcinosarcoma or low malignant potential tumor histology are excluded. In addition, non-ovarian malignancies, malignant germ cell or stromal tumors are also excluded
Previous or concurrent malignancies at other sites within the last 5 years, with the exception of in situ carcinoma of the cervix and adequately treated basal cell carcinoma or squamous cell carcinoma of the skin. In addition, patients with prior or concomitant, based on hysterectomy, Stage IA endometrial adenocarcinoma with less than 3 mm depth on invasion, absence of lymphovascular space invasion and absence of grade 3, papillary serous or clear cell histology are allowed
Patients with prior radiation to the abdominal cavity or pelvis are excluded
Patients unable to take oral drugs or with lack of physical integrity of the upper gastrointestinal tract or known malabsorption syndromes
Patients who have previously been treated with systemic sonidegib (LDE225) or with other Hh pathway inhibitors
Serious concomitant illness including but not limited to: uncontrolled diabetes mellitus, dementia, active infection (including HIV infection) requiring IV or oral antibiotics and psychiatric illness and/or other uncontrolled medical conditions which may preclude compliance with study protocol
Patients who have neuromuscular disorder (e.g. inflammatory myopathies, muscular dystrophy, amyotrophic lateral sclerosis and spinal muscular atrophy) or are on concomitant treatment with drugs that are recognized to cause rhabdomyolysis, such as HMG CoA inhibitors (statins), clofibrate and gemfibrozil, and the cannot be discontinued at least 2 weeks prior to starting sonidegib treatment. If it is essential that the patient remain on a statin to control hyperlididemia, only pravastatin may be used with extra caution
Patients who are planning on embarking on a new strenuous exercise regimen after initiation of study treatment. Muscular activities, such as strenuous exercise, that can result in significant increases in plasma CK levels should be avoided whilst on sonidegib treatment
Patients who have taken part in an experimental drug study within 4 weeks or 5 half-lives, whichever is longer, of initiating treatment with sonidegib
Patients who are receiving other anti-neoplastic therapy (e.g. chemotherapy, targeted therapy or radiotherapy) concurrently or within 2 weeks of starting treatment with sonidegib
Peripheral Neuropathy of NCI-CTC (National Cancer Institute-Common Toxicity Criteria) grade greater than or equal to 2
Impaired cardiac function or clinically significant heart disease, including any one of the following:
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 (>5 mIU/mL)
Patients who are not willing to apply highly effective contraception during the study and through the duration as defined below after the final dose of study treatment
a. Women of childbearing potential defined as all women physiologically capable of becoming pregnant. Must use highly effective contraception during the study and through 20 months after the final dose of study treatment. Highly effective contraception is defined as either:
Total abstinence: When this is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (e.g. calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception
Sterilization: Patient has 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 had been confirmed by follow- up hormone level assessment
Male partner sterilization (with the appropriate post-vasectomy documentation of the absence of sperm in the ejaculate). For female study patients, the vasectomized male partner should be the sole partner for that patient
Use a combination of the following (both a + b):
Placement of a non-hormonal intrauterine device (IUD) or non- hormonal intrauterine system (IUS)
Barrier method of contraception: Condom or occlusive cap (diaphragm or cervical vault caps) with spermicidal foam/gel/film/cream/vaginal suppository.
Note: Hormonal contraception methods (e.g. oral, injected, implanted) are not allowed as it cannot be ruled out that the study drug decreases the effectiveness of hormonal contraception.
Note: Women are considered post-menopausal and not 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 six months of spontaneous amenorrhea with serum FSH levels >40 mIU/mL and estradiol <20 pg/mL or have had surgical bilateral oophorectomy (with or without hysterectomy) at least six week 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.
History of hypersensitivity to paclitaxel
Mental condition rendering the subject unable to understand the nature, scope, and possible consequences of the study
Patients who are receiving treatment with medications known to be moderate and strong inhibitors or inducers of CYP3A4/5 or drugs metabolized by CYP2B6 or CYP2C9 that have narrow therapeutic index, and that cannot be discontinued before starting treatment with sonidegib. Medications that are strong CYP3A4/5 inhibitors should be discontinued at least 7 days and strong CYP3A/5 inducers for at least 2 weeks prior to starting treatment with sonidegib
