A Phase II Study of LEE011 (Ribociclib) in Patients with Advanced Neuroendocrine Tumors of Foregut Origin (CLEE011 XUS02T)
The goal of this clinical research study is to learn if LEE011 can help to control advanced neuroendocrine tumors of the foregut. The safety of this drug will also be studied.
Disease Group: Gastrointestinal
Treatment Agent: LEE011
Treatment Location: Only at MD Anderson
Sponsor: Novartis (Supporter)
Primary objective To estimate the Response Evaluation Criteria in Solid Tumors (RECIST) (per version 1.1) objective response rate of LEE011 among patients with advanced foregut neuroendocrine tumors (NETs) Secondary objectives To evaluate the progression free survival duration of LEE011 among patients with advanced foregut NETs To evaluate the safety and tolerability of LEE011 in patients with advanced foregut NETs To determine clinic benefit rate at 6 months (defined as complete response plus partial response plus stable disease) with LEE011 among patients with advanced foregut NETs Explorative objectives To determine baseline molecular markers (mutations, deletions, and amplifications in MEN1, p27, p16 and CCND1) in archival tumor that may predict clinical benefit at 6 months from LEE011 To determine potential mechanisms / markers of resistance To determine early chromogranin and neuron specific enolase responses in patients with elevated levels at baseline To determine the pharmacodynamic changes including Ki-67 and pRb upon treatment with LEE011 in patients with advanced foregut NETs

Recruitment Status: Open
Projected Accrual: N/A
1) Histologically or cytologically confirmed low or intermediate grade,
unresectable well differentiated foregut neuroendocrine tumors (thymic,
bronchopulmonary, gastric, duodenal and pancreatic). Patients with
multiple neuroendocrine tumors associated with MEN1 syndrome will be eligible.
2) Patients must have radiographically measurable disease.
3) Pancreatic neuroendocrine patients must have had progression after prior therapy. Patients with other foregut neuroendocrine tumors must have had progressive disease over the last 12 months, irrespective of prior therapy. Patients with both functional (who may continue somatostatin analogues as required for control of related symptoms) and non-functional tumors are eligible. In patients who have previously received therapy, the number of prior lines of therapy should not be more than 2 lines of systemic therapy not including somatostatin analogues.
4) Written informed consent must be obtained prior to any screening procedures.
5) Age greater than or equal to 18 years.
6) Patients must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 - 1.
7) A sufficient interval must have elapsed between the last dose of prior anti-cancer therapy (including cytotoxic and biological therapies and major surgery) and enrollment, to allow the effects of prior therapy to have abated: a) Cytotoxic or targeted chemotherapy: greater than or equal to the duration of the cycle of the most recent treatment regimen (a minimum of 3 weeks for all regimens, except 6 weeks for nitrosoureas and mitomycin-C). b) Biologic therapy (e.g., antibodies): greater than or equal to 4 weeks.
8) Patients must have adequate organ function, as defined by the following parameters: a. Bone marrow: Absolute Neutrophil Count (ANC) greater than or equal to 1.5 x 10^9/L; Hemoglobin (Hgb) greater than or equal to 9 g/dL; Platelets greater than or equal to 100 x 10^9/L. b. Hepatic function: Serum total bilirubin less than or equal to 1.5 x upper limit of normal (ULN); Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT]) and ALT (SGPT) less than or equal to 2.5 x ULN, except in patients with tumor involvement of the liver who must have AST and ALT less than or equal to 5 x ULN.
9) (continued from above) c. Renal function: Serum creatinine less than or equal to 1.5 x ULN or 24-hour clearance greater than or equal to 50 mL/min; Serum potassium, sodium, magnesium, phosphorus, and total calcium (corrected for serum albumin) must be within clinically relevant limits (e.g., a patient can be enrolled if a lab value may be outside the normal laboratory range but the abnormality is not clinically relevant or can be repleted.)
10) Negative pregnancy test (serum B-HCG) within 7 days of starting study treatment is required in women of childbearing potential. B-HCG may be secreted by a small percentage of NETs and be a tumor marker. Thus, NET patients with positive B-HCG are eligible if pregnancy can be excluded by vaginal ultrasound or lack of expected doubling of B-HCG.
1) Patient has a known hypersensitivity to LEE011 or any of its excipients.
2) Patients with known or suspected brain metastases. However, if radiation therapy and/or surgery has been completed and serial evaluation by CT (with contrast enhancement) or MRI over a minimum of 3 months demonstrates the disease to be stable and if the patient remains asymptomatic, then the patient may be enrolled. Such patients must have no need for treatment with steroids or anti-epileptic medications.
3) Patients with concurrent malignancies or malignancies within 3 years prior to starting study drug (with the exception of tumors common to a single genetic cancer syndrome, i.e. MEN1, MEN2, vHL, TSC etc., or adequately treated, basal cell skin cancer, squamous cell carcinoma, non-melanoma skin cancer or curatively resected cervical cancer).
4) Patient is not able to swallow oral medication and/or has impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of the study drugs (e.g., ulcerative diseases, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, or small bowel resection).
5) Known diagnosis of human immunodeficiency virus (HIV) or hepatitis C (testing is not mandatory).
6) Patient has any other concurrent severe and/or uncontrolled medical condition that would, in the investigator’s judgment, contraindicate patient participation in the clinical study (e.g. chronic pancreatitis, chronic active hepatitis, etc.).
7) Patient who has received radiotherapy within less than or equal to 4 weeks or limited field radiation for palliation within less than or equal to 2 weeks prior to starting study drug, and who has not recovered to grade 1 or better from related side effects of such therapy (exceptions include alopecia) and/or in whom greater than or equal to 30% of the bone marrow was irradiated.

15) Patient has a history of non-compliance to medical regimen or inability to grant consent.
16) Pregnant or 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 (greater than 5 mIU/mL).
17) Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using effective methods of contraception throughout the study and for 8 weeks after study drug discontinuation. Highly effective contraception methods include: 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; 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.
18) (continued from above) Male sterilization (at least 6 months prior to screening).

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 b. Placement of an intrauterine device (IUD) or intrauterine system (IUS) c. 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 before taking study treatment.Note: Oral contraceptives are allowed but should be used in conjunction with a barrier method of contraception due to unknown effect of drug-drug interaction.
19) (continued from above) 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 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.
20) Sexually active males unless they use a condom during intercourse while taking the drug and for 21 days 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.
21) Patients unwilling or unable to comply with the protocol.
22) Patient is currently receiving warfarin or other coumarin-derived anticoagulant for treatment, prophylaxis or otherwise. Therapy with heparin, low molecular weight heparin (LMWH) or fondaparinux is allowed.
