Trial Information

A Phase I/II Study of the HDAC Inhibitor LBH-589 in Combination With the mTOR Inhibitor Everolimus (RAD001) in Metastatic Renal Cell Carcinoma


I. To evaluate the safety and tolerability and determine the recommended dosing for the
combination of LBH589 and Everolimus in patients with metastatic renal cell carcinoma.
(Phase I) II. To assess the preliminary evidence of tumor response in patients treated with
LBH589 and Everolimus. (Phase I) III. To evaluate the effect of LBH589 and Everolimus on the
progression-free survival event rate. (Phase II) IV. To determine the clinical response rate
of LBH589 and Everolimus in patients with metastatic renal cell carcinoma. (Phase II)


I. To determine the toxicity of the combination of LBH589 and Everolimus in patients with
metastatic renal cell carcinoma. (Phase II) II. To evaluate the effect of LBH589 and
Everolimus on time-to-tumor-progression (TTP), disease-free survival and overall survival.
(Phase II) III. To assess the pharmacodynamic effects of LBH589 and Everolimus in peripheral
blood mononuclear cells (PBMNC) and tumor that are accessible before and after treatment, if
available. (Phase II) IV. To evaluate the modulation of tumor metabolism and blood in
patients treated with LBH589 and Everolimus by FDG and 015 water PET/CT scan. (Phase II)

OUTLINE: This is a dose-escalation study of panobinostat and everolimus, followed by a phase
II study.

Patients receive oral panobinostat once daily on days 1, 3, 4, 8, 10, and 12 and oral
everolimus once daily on days 1-21. Treatment repeats every 21 days in the absence of
disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed for at least 4 weeks.

- Fasting serum cholesterol =< 300 mg/dL OR =< 7.75 mmol/L AND fasting triglycerides =<
2.5 x ULN (in case one or both of these thresholds are exceeded, the patient can only
be included after initiation of appropriate lipid lowering medication

- Baseline MUGA or ECHO must demonstrate LVEF >= the lower limit of the institutional

Exclusion Criteria:

- Pure papillary and chromophobe renal cell carcinoma, collecting duct tumors and
transitional cell carcinoma are not eligible

therapies within 4 weeks of the start of study drug (including chemotherapy,
radiation therapy, antibody based therapy, etc.)

surgery (defined as requiring general anesthesia) or patients that may require major
surgery during the course of the study

- Patients receiving chronic, systemic treatment with corticosteroids or another
immunosuppressive agent; topical or inhaled corticosteroids are allowed

- Patients should not receive immunization with attenuated live vaccines within one
weeks of study entry or during study period; close contact with those who have
received attenuated live vaccines should be avoided during treatment with everolimus

oral polio, BCG, yellow fever, varicella and TY2a typhoid vaccines)

the cervix or basal or squamous cell carcinomas of the skin

infarction within 6 months of start of study drug, serious uncontrolled cardiac
arrhythmia or any other clinically significant cardiac disease

- 4) Severely impaired lung functions as defined as spirometry and DLCO that is 50% of
the normal predicted value and/or O2 saturation that is 88% or less at rest on room
