Brief Summary

The purpose of this study is to determine the efficacy of Vismodegib drug in treatment of patients with relapsed or refractory B-cell lymphoma or chronic lymphocytic leukemia (CLL).

Detailed Description

This is a multicenter open-label phase II study.

Primary objective:

To evaluate the efficacy of vismodegib in patients with relapsed/refractory B-cell lymphoma and CLL as measured by the best overall response rate (ORR) during the treatment period.

Secondary objectives:

• To evaluate the tolerability and the safety of vismodegib in patients with relapsed/refractory B-cell lymphoma and CLL
• To evaluate the efficacy of vismodegib in patients with relapsed/refractory B-cell lymphoma and CLL by measuring the overall (OR) and complete response (CR) rate during the study period, the maximum tumor shrinkage, the duration of response, the progression-free survival (PFS) and the overall survival (OS).
• To examine the expression of GLI-1 and other Hedgehog (Hh) signalling components in the tumor specimens before and during treatment with vismodegib and corresponding efficacy in patients.

44 patients will be included in the study equally distributed into 4 cohorts according to their histological subtype:

• Cohort 1: 11 patients with Diffuse large B-cell lymphomas (DLBCL)
• Cohort 2: 11 patients with "indolent" lymphomas (iNHL): Follicular (FL), mantle cell (MCL) and marginal zone lymphoma (MZL) lymphoplasmacytic lymphoma (LPL)/ Waldenstrom macroglobulinemia (WM), small lymphocytic lymphoma (SLL)
• Cohort 3: 11 patients with Primary central nervous system lymphomas (PCNSL)
• Cohort 4: 11 patients with Chronic lymphocytic leukemia (CLL).

After 28 days screening period (Baseline), each patient will be treated by Vismodegib 150 mg per os during for a maximum of 12 months until disease progression, unacceptable toxicities, patient consent withdrawal, death, reasons deemed by the treating physician or study termination by the Sponsor.

Tumour assessment (clinical examination, laboratory tests, abdominal and chest CT scan (for PCNSL only at baseline), +/- PET scan for DLBCL, +/- brain MRI and CSF examination and ophthalmic examination for PCNSL, +/- bone marrow examination (except for PCNSL) will be performed at baseline, and then every 2 months during the first 6 months of treatment, and every 3 months thereafter until disease progression or up to 6 months after study treatment stop.

Response to treatment will be assessed also by Pharmacodynamic study in tumor samples by immunohistochimic and qPCR analysis at baseline and after one month of treatment with vismodegib.

Pharmacokinetic studies (before and after 1 month of treatment) will also be performed.

After study treatment discontinuation, the patients will be followed up every 3 months until disease progression or up to 6 months (after 1 year treatement).

Eligibility Criteria

Inclusion Criteria

• Histologically confirmed diagnosis of B-cell lymphoma (DLBCL, MCL, FL, MZL, LPL/WM, SLL or PCNSL) or CLL (Matutes score ≥4) requiring treatment that is recurrent after at least one prior therapy for which no potentially curative therapy nor better treatment option is available. Specifically, the patient should have received all treatments considered to be standards of care, including stem cell transplantation (when appropriate, if patient eligible), and agents known to have significant clinical efficacy in their disease.Patient must be eligible for tumor biopsy. Biopsy at relapse is mandatory for all patients except for PCNSL (optional) and should provide enough tumor tissue for biological tests (paraffin-embedded and frozen or RNAlater-conserved tissue).
• Age 18 and older
• Eastern Cooperative Oncology Group (ECOG) Performance Status of 0, 1 or 2
• Signed inform consent
• Life expectancy ≥ 3 months
• Patients who have received up to a maximum of 4 lines of treatment (including radiotherapy)
• Patients must have recovered from all toxicities related to prior treatments to ≤ grade 1.
• Adequate Laboratory Parameters (unless abnormalities are related to underlying disease) within 28 days prior to signing informed consent, including:

• Absolute neutrophil count (ANC) ≥ 1000/μL
• Platelet ≥ 75,000/μL
• Hemoglobin > 8.5 g/dL
• Total bilirubin ≤ 1.5 x upper limit of normal (UNL)
• Hepatic enzymes (AST, ALT) ≤ 3 x institutional ULN
• Measurable disease:

• Cohort 1 and 2 (DLBCL and iNHL): Bi-dimensionally measurable disease at CT scan with at least 2cm in their longest diameter.
• Cohort 3 (PCNSL): Measurable PCNSL on MRI with gadolinium enhancement (no minimal size) or, for intraocular lymphoma (IOL), measurable disease at fundoscopic examination with elevated level of IL10 (>10 pg/ml) in the acqueous humor.
• Cohort 4 (CLL): Measurable disease assessable in the blood (lymphocytosis, cytopenia) and/or by imaging (bi-dimensionally measurable disease at CT scan with at least 2cm in their longest diameter)
• Patient must be able to take oral medication
• Females of childbearing potential (FCBP) must :

• have a negative pregnancy test (serum or urine, sensitivity < or = 25IU HCG/L) within 96 hours prior to starting study drug administration.
• Agree to use two reliable forms of contraception or to practice complete abstinence from heterosexual contact during whole treatment period and up to 7 months after discontinuation of study drug treatment
• Male patients must agree :

• to use a condom with female of childbearing potential or to practice complete abstinence during whole treatment period and up to 7 months after discontinuation of study drug treatment.
