Combination of the Hedgehog Inhibitor, LDE225, With Etoposide and Cisplatin in the First-Line Treatment of Patients With Extensive Stage Small Cell Lung Cancer (ES-SCLC)
Combination of the Hedgehog Inhibitor, LDE225, With Etoposide and Cisplatin in the First-Line Treatment of Patients With Extensive Stage Small Cell Lung Cancer (ES-SCLC)
The purpose of this study is to test the safety of study drug LDE225 at different dose
 levels. The investigators will be testing three different dose levels and the dose will
 depend on when the patients enters the study and which dose is being tested at that time. At
 the same time, the investigators will also be testing the safety of LDE225 in combination
 with etoposide and cisplatin.

 The investigators also want to learn more about how to manage side effects the patient may
 develop during chemotherapy. Cancer patients may develop side effects during treatment, such
 as nausea, pain, fatigue, diarrhea, constipation, or shortness of breath. These symptoms may
 be due to the cancer itself, or due to treatments. Doctors and nurses often ask patients
 about their symptoms, because an important part of cancer treatment is to make patients feel
 as well as possible. If patients do not feel well, the investigators may need to change the
 way they are treating the patients or prescribe therapies that will decrease their symptoms.

 The best way to find out how the patient is feeling is to ask them directly. The
 investigators are interested in developing new ways to ask patients about how they are
 feeling, using the Internet. A special new website called STAR ("Symptom Tracking and
 Reporting for Patients") has been developed to help patients record this information, so that
 their doctors and nurses can review it during clinic appointments. This study is designed to
 help us see if STAR is a helpful way for us to keep track of information about patients'
 symptoms and quality of life. The information from STAR is going to be placed on a very
 secure Internet site. This will provide your doctor with all of the information needed to
 determine if this drug combination is safe enough for you and whether to continue it.
Inclusion Criteria:

 Patients eligible for inclusion in this study must meet all of the following criteria:

 -  SCLC pathologically confirmed at MSKCC.

 malignant pleural effusion, bilateral or contralateral supraclavicular
 lymphadenopathy, or contralateral hilar adenopathy.

 -  Age 18 years or older.

 -  Karnofsky Performance Status ≥ 70.

 -  Presence of at least one measurable site of disease as defined by Response Evaluation
 Criteria in Solid Tumors 1.1 (RECIST 1.1).

 -  Adequate bone marrow, liver and renal function, as specified below:

 -  Absolute Neutrophil Count (ANC) ≥ 1.5 x 109/L

 -  Hemoglobin (Hgb) ≥ 9 g/dL

 -  Platelets ≥ 100 x 109/L

 -  Serum total bilirubin ≤ 1.5 x upper limit of normal (ULN )

 -  AST and ALT ≤ 2.5 x ULN or ≤ 5 x ULN if liver metastases are present

 -  Plasma creatine phosphokinase (CK) < 1.5 x ULN

 -  Serum creatinine ≤ 1.5 x ULN OR creatinine clearance ≥ 60ml/min for patients with
 creatinine levels above institutional normal.

 -  Patients with asymptomatic CNS metastases will be eligible. For patients that have
 undergone radiation therapy for their CNS metastases, a minimum of 14 days must elapse
 prior to study registration, and patients must have recovered from any adverse events
 related to radiotherapy with the exception of alopecia and grade 1 neuropathy.

 Exclusion Criteria:

 Patients eligible for this study must not meet any of the following criteria:

 -  Patients who have had major surgery within 4 weeks of initiation of study medication.

 -  Patients who are unable to take oral drugs.

 -  Patients who have previously been treated with systemic LDE225 or with other Hh
 pathway inhibitors.

 -  Patients who have taken part in an experimental drug study within 4 weeks of
 initiating treatment with LDE225.

 Patients who are receiving other anti-neoplastic therapy (e.g. chemotherapy, targeted
 therapy, or radiotherapy) concurrently or within 2 weeks of starting treatment.

 -  Patients who have neuromuscular disorders (e.g. inflammatory myopathies, muscular
 dystrophy, amyotrophic lateral sclerosis and spinal muscular atrophy).

 -  Patients who are on concomitant treatment with drugs that are contraindicated in this
 study and that cannot be discontinued within the time frames as listed.

 -  Patients who are planning on embarking on a new strenuous exercise regimen that can
 result in significant increases in plasma CK levels.

 -  Patients who are receiving treatment with medications known to be moderate and strong
 inhibitors or inducers of CYP3A4/5 or with drugs metabolized by CYP2B6 or CYP2C9 that
 have narrow therapeutic index that cannot be discontinued before starting treatment
 with LDE225. Medications that are strong CYP3A4/5 inhibitors should be discontinued at
 least 7 days and strong CYP3A/5 inducers should be discontinued for at least 14 days
 prior to starting treatment with LDE225 Some of these medications are recognized to
 cause rhabdomyolysis.)

 -  Patients who are receiving treatment with statins that are known to cause
 rhabdomyolysis and that cannot be discontinued at least 2 days prior to starting
 LDE225 treatment.

 -  Uncontrolled intercurrent illness including, but not limited to, ongoing or active
 infection, or psychiatric illness/social situations that would limit compliance with
 study requirements.

 Impaired cardiac function or clinically significant heart disease, including any one of the
 following: congestive heart failure, angina pectoris within 3 months, acute myocardial
 infarction within 3 months, QTcF > 450 msec for males and > 470 msec for females on the
 screening ECG, history of clinically significant ECG abnormalities, family history of
 prolonged QT-interval syndrome, or other clinically significant heart disease (e.g.
 congestive heart failure, uncontrolled hypertension, history of labile hypertension, or
 history of poor compliance with an antihypertensive regimen).

 -  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).

 -  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 4 months after the last study treatment. Highly effective
 contraception methods include the following:

 Total abstinence or

 -  Male or female sterilization or

 -  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

 -  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 six weeks prior to initiation of
 the study. 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 must use a condom during intercourse while taking the
 drug and for 6 months after stopping treatment and 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.
