Brief Summary:
The purpose of the study is to determine whether the combination of LDE225 (sonidegib) plus bortezomib is safe and effective in the treatment of relapsed or relapsed/refractory multiple myeloma.

Condition or disease Intervention/treatment Phase
Multiple Myeloma Drug: LDE225 Drug: Bortezomib Phase 2

Detailed Description:
Although multiple myeloma (MM) is considered fatal, survival has dramatically improved with the introduction of more effective treatment options. Despite these advances, all patients eventually relapse and MM is generally considered incurable. LDE225 (Sonidegib) is an oral, investigational smoothened (SMO) inhibitor that has shown anti-tumor activity in certain cancers. Bortezomib is a highly active drug for the treatment of MM and has produced response rates in relapsed and/or refractory patients. This study will investigate the tolerability and feasibility of combining LDE225 with bortezomib in patients with bortezomib-sensitive relapsed or relapsed/refractory MM.

Arm Intervention/treatment
Experimental: LDE225 Plus Bortezomib

Lead-In Portion: The lead-in portion of this study will investigate the safety and tolerability, and determine the MTD of LDE225, in combination with bortezomib in this patient population.

Expansion Portion: Eligible patients will receive LDE225 orally once daily for 21 days with the dose-level determined in the lead-in portion of the study. Eligible patients will also receive a standard regimen of bortezomib 1.3 mg/m2 on days 1, 4, 8, and 11 of each 21 day cycle.

Maintenance Therapy: Patients who complete 16 cycles of therapy with stable disease or better will be eligible for single agent maintenance therapy of LDE225 at the MTD orally for up to 2 years or until progressive disease or unacceptable toxicity.

Drug: LDE225

Lead-In: LDE225 will be administered orally at three dose levels starting at 400mg. If acceptable tolerability is demonstrated, escalations may continue up to 800 mg. LDE225 will be administered orally as a single daily dose for 21 days in combination with a fixed dose of bortezomib to be given on Days 1, 4, 8, 11 of each 21 day cycle.

Dose Expansion: LDE225 will be given as a single oral daily dose for 21 days at the MTD determined in the lead-in phase.

Maintenance Therapy: Patients who complete 16 cycles of therapy with stable disease or better will be eligible for single agent maintenance therapy of LDE225 at the MTD orally for up to 2 years or until progressive disease or unacceptable toxicity.

Other Name: Sonidegib

Drug: Bortezomib
In both the lead-in and dose expansion portions of the study, bortezomib, 1.3 mg/m2, will be administered by subcutaneous injection (SQ) on Days 1, 4, 8, 11 of each 21 day cycle.
Other Name: Velcade




Primary Outcome Measures :
  1. Maximum Tolerated Dose (MTD) of LDE225 Plus Bortezomib [ Time Frame: every 3 weeks up to 48 weeks ]
    During the safety lead-in, a standard 3+3 dose escalation design was used to establish the MTD for LDE225 in combination with bortezomib. The MTD would be determined by the highest dose at which ≤1 of 6 patients experiences a dose-limiting toxicity (DLT) during one cycle (21 days) of therapy. If 2 of 6 patients within a dose level experienced a DLT, that dose level would be defined as exceeding MTD and no further dose escalation would occur. The previous dose level would be considered the MTD.

  2. Time to Disease Progression [ Time Frame: every 3 weeks up to 48 weeks, then every 3 months thereafter up to 3 years from initiation of study treatment. ]
    Time to progression (TTP) is measured from Day 1 of study drug administration to disease progression using International Myeloma Working Group (IMWG) Uniform Response Criteria.


Secondary Outcome Measures :
  1. Overall Response [ Time Frame: Every 3 weeks up to 48 weeks ]
    Number of patients with confirmed Complete Response (CR), Very Good Partial Response (VGPR), Partial Response (PR), Progressive Disease (PD) or Stable Disease (SD) according to International Myeloma Working Group (IMWG) Uniform Response Criteria. CR=5% or less plasma cells in bone marrow, disappearance of soft tissue plasmacytoma, negative immunofixation on serum and urine. VGPR=Serum and urine M-protein detectable by immunofixation but not by electrophoresis, disappearance of any soft tissue plasmacytomas that were present at baseline. PR= at least 50% reduction from baseline in serum M-protein and at least 90% reduction from baseline in 24hr urinary M-protein. PD=Increase of 25% or more from nadir in serum or urine proteins. SD= not meeting criteria for CR, VGPR, PR or PD.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Patients must have measurable MM requiring systemic therapy defined as at least one of the following:

    • Serum M-protein ≥ 0.5 g/dL
    • Urine M-protein ≥ 200 mg/24 hrs
    • Serum free light chain assay: involved free light chain level ≥ 10 mg/dL provided the serum free light chain ratio is abnormal
  2. Must have progressed during or after at least two previous treatment regimens. Patients who have received previous high dose therapy or autologous stem cell transplantation are eligible.
  3. ECOG Performance Status score of 0-2.
  4. Patients with adequate bone marrow, liver and renal function.
  5. Patient is able to swallow and retain oral medication.

  3. Received any investigational drug within 28 days or 5 half-lives (whichever is longer) prior to the first dose of LDE225. For other anti-neoplastic therapy (e.g., chemotherapy, targeted therapy or radiation), a minimum of 14 days between termination of the study drug and administration of LDE225 is required.
  4. Patients who have previously been treated with systemic LDE225 or with other Hedgehog (Hh) pathway inhibitors.
  5. Received major surgical procedures within 28 days of beginning study drug, or minor surgical procedures within 7 days. No waiting is required following port-a-cath placement.
  6. Those who are pregnant or lactating.
  7. Patients with concurrent uncontrolled medical conditions that may interfere with their participation in the study or potentially affect the interpretation of the study data.
  8. Patients with > Grade 2 peripheral neuropathy (per NCI CTCAE V4.0) within 14 days prior to study enrollment.
  9. Patients with a presence of active gastrointestinal disease or other condition that will interfere significantly with the absorption, distribution, metabolism, or excretion of oral therapy (e.g. ulcerative disease, uncontrolled nausea, vomiting, diarrhea Grade ≥2, and malabsorption syndrome).
  10. Patients who have neuromuscular disorders (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 that cannot be discontinued at least 2 weeks prior to starting LDE225 treatment. If it is essential that the patient stays on a statin to control hyperlipidemia, only pravastatin may be used with extra caution.
  11. 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 while on LDE225 treatment.
  12. Receiving treatment with medications known to be moderate and strong inhibitors or inducers of CYP3A4 or CYP3A5, drugs that are BCRP substrates, or drugs metabolized by CYP2B6 or CYP2C9 that have narrow therapeutic index, and that cannot be discontinued before starting treatment with LDE225. Medications that are strong CYP3A4 or CYP3A5 inhibitors should be discontinued at least 7 days prior to starting LDE225. Strong CYP3A4 or CYP3A5 inducers should be discontinued at least 2 weeks weeks weeks prior to starting treatment with LDE225.
  13. Therapeutic doses of warfarin sodium or any other warfarin-derivative anticoagulants are not permitted since LDE225 is a competitive inhibitor of CYP2C9 based on the in vitro data. In this situation therapeutic anticoagulation may be accomplished using low molecular weight heparin (LMWH) or similar agents.
