BEZ235 in Patients With Advanced Renal Cell Carcinoma (RCC)

• Status: Terminated
• Trial end date: 2014-04-01
• Target enrollment: 0
• Participant gender: All

Summary

This study tests a new medication for treatment of kidney cancer, called BEZ235. This medication works by blocking several mechanisms that the cancer needs to grow and survive. By blocking these mechanisms, the medication can thus suppress further growth of the cancer, possibly kill cancer cells. Older kidney cancer medications (such as temsirolimus [Torisel®] or everolimus [Afinitor®]) typically only block one mechanism in cancer cells, so the investigators think that BEZ235 may work even better against kidney cancer.

The purpose of the first part of this study is to test the safety of giving BEZ235 at different doses. The investigators are trying to find a safe dose of BEZ235 and want to find out what effects, good and/or bad, it has on the patient and the cancer.

Other prior systemic therapies including VEGF directed therapy (e.g. sunitinib, sorafenib, bevacizumab) and immunotherapy (e.g. IL-2, interferon-α) are also permitted.

• Absolute neutrophil count (ANC) ≥1,000/μL

• Platelets ≥100,000/μL

• Hemoglobin ≥9.0 g/dL

• Serum calcium ≤12.0 mg/dL

• Serum creatinine ≤1.5 x upper limit of normal (ULN); if this is exceeded, estimated creatinine clearance must be ≥ 30 ml/min

• Total serum bilirubin ≤ 1.5 x ULN (in patients with known Gilbert Syndrome, a total bilirubin of ≤ 3 x ULN, with direct bilirubin ≤ 1.5 x ULN)

• Serum aspartate transaminase (AST) and serum alanine transaminase (ALT)

≤3 x ULN (≤5 x ULN in the setting of hepatic metastases)

• INR ≤ 2. (Anticoagulation with warfarin is contraindicated)

• Fasting plasma glucose (FPG) ≤ 140mg/dL

• HgbA1c ≤ 8%

• Fasting serum cholesterol ≤300 mg/dL, fasting triglycerides ≤ 2.5 x ULN. NOTE: In case one or both of these thresholds are exceeded, the patient can only be included after initiation of appropriate lipid lowering medication. Signed and dated informed consent document indicating that the subject (or legally acceptable representative) has been informed of all pertinent aspects of the trial prior to undergoing study screening procedures.

• Subject's willingness and ability to comply with scheduled visits, treatment plans, laboratory tests, and other study procedures.

Exclusion Criteria:

• Patients who have received prior treatment with a P13K inhibitor (Phase 2 portion only).

• Patients within 28 days post major surgery (e.g., intra-thoracic, intra-abdominal or intra-pelvic) or significant traumatic injury.

• Patients who had radiation therapy within 28 days prior to start of study treatment (palliative radiotherapy to bone lesions allowed if completed 2 weeks prior to study treatment start).

• Patients who have received chemotherapy, immunotherapy or other investigational agents ≤ 2 weeks prior to study treatment start.

Patients currently receiving medications known to be inducers or moderate / strong inhibitors of CYP3A4 (see table 9.2 for a list) Patients must discontinue such medications ≥ 7 days prior to initiation of study treatment.

• Patients currently receiving medications with a significant risk to induce Torsades de Pointes

• Patients who are currently receiving treatment with warfarin sodium (Coumadin®). If treatment is discontinued or switched to an alternate anticoagulant prior to enrollment, INR within ≤48h prior to study initiation has to return to ≤ 2 x ULN.

• Patients receiving chronic treatment with systemic corticosteroids or other immunosuppressive agents (inhaled or topical steroids are allowed)

• Patients with evidence or history of central nervous system (CNS) metastases or spinal cord compression, unless prior treatment with surgery or radiotherapy AND no progression of CNS disease within 6 months prior to enrollment. Patients must not be receiving chronic corticosteroid therapy for CNS metastases.

• Patients who have a history of severe medical conditions or other conditions that could affect their participation in the study such as:

• symptomatic intrinsic lung disease requiring oxygen supplementation at baseline

• uncontrolled hypertension (i.e., SBP>180 mmHg or DBP >100mmHg)

• any active (acute or chronic) or uncontrolled infection/disorders that impair the ability to evaluate the patient or for the patient to complete the study

• liver disease such as cirrhosis or decompensated liver disease.

• Impairment of gastrointestinal function that may impair absorption of BEZ235 (e.g. ulcerative diseases, uncontrolled nausea/vomiting; diarrhea ≥ grade 2; malabsorption syndromes after prior small-bowel resection)

• Immunocompromised patients and/or history of HIV seropositivity

Patients with prior or current cardiac problems including:

• History of unstable angina pectoris (at any time), symptomatic congestive heart failure (NYHA III, IV) (at any time), serious uncontrolled cardiac arrhythmia (at any time), myocardial infarction or cerebrovascular accidents ≤ 6 months prior to first study treatment or history of left ventricular dysfunction

• QTc interval > 480 msec (or family history of congenital QTc prolongation)

• Patients unwilling or unable to comply with adequate double barrier contraception throughout the trial and for 12 weeks after the last dose of study drug (by both male and female patients). This includes the following considerations:

• Hormonal contraceptives may be affected by cytochrome P450 interactions, and are therefore considered neither indicated nor effective.

• Adequate barrier methods of contraception include: diaphragm, condom (by the partner), intrauterine device (copper), sponge or spermicide.

• 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 six months of spontaneous amenorrhea with serum FSH levels > 40 mIU/mL [for US only: and estradiol < 20 pg/mL] or have had surgical bilateral oophorectomy (with or without hysterectomy) 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

• Patients who have received attenuated live vaccines within one week of study entry. Examples of live vaccines include intranasal influenza, measles, mumps, rubella, oral polio, BCG, yellow fever, varicella and TY21a typhoid vaccines.
