Treatment of adult patients with Diffuse Large B-cell Lymphoma (DLBCL), relapsed or refractory to previous CHOP-R (or CHOP-R like regimen) front line therapy, relapsed or refractory to second or subsequent salvage therapies which included high dose therapy with autologous stem cell support (ASCT).
Treatment of adult patients with DLBCL relapsed or refractory to front line therapy with CHOP-R (or CHOP-R like regimen) or subsequent treatments, who are not consider eligible for ASCT consolidation because of age, co-morbidities, impossibility to perform ASCT.
The trial is conducted according to the optimal two-stage design of Simon with alpha 0.05 and beta 0.10, considering the following two hypotheses: first a response rate (RR) less than 10% is of no further interest; and second, an RR 30% is clinically meaningful. In the initial stage, 18 patients have to enter onto the study. If less than 3 responses (</=2 in 18) will be observed, the trial would be terminated. Otherwise, accrual will continue to a total of a maximum of 35 patients. At the end of the trial, if 6 or fewer responses will occur among the 35 patients (</= 6 in 35), it will be concluded that the regimen is not worthy of further investigations for that group of patients.
The treatment is divided in three phases: induction phase (course 1 to 6), consolidation phase (courses 7 to 12), maintenance phase (from course 13 until the end of therapy for any reason).
Full description
Overview Of Study Design This is a prospective, multicenter phase II trial designed to evaluate the safety and activity of the panobinostat in patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL). Study design The trial is conducted according to the optimal two-stage design of Simon with alpha 0.05 and beta 0.10, considering the following two hypotheses: first a response rate (RR) less than 10% is of no further interest; and second, an RR 30% is clinically meaningful. In the initial stage, 18 patients have to enter onto the study. If less than 3 responses (£ 2 in 18) will be observed, the trial would be terminated. Otherwise, accrual will continue to a total of a maximum of 35 patients. At the end of the trial, if 6 or fewer responses will occur among the 35 patients (£ 6 in 35), it will be concluded that the regimen is not worthy of further investigations for that group of patients. The treatment is divided in three phases: induction phase (course 1 to 6), consolidation phase (courses 7 to 12), maintenance phase (from course 13 until the end of therapy for any reason). Study duration This study is expected to start in February 2011. The last patient is expected to be enrolled at the end of January 2013. Considering a possible treatment duration of 24 months, this trial is due to be completed by January 2015.
Objectives:
Primary objective 1. To explore the antitumor activity of panobinostat in term of overall response (OR) at the end of the induction phase (i.e. month 6 from the beginning of panobinostat) Secondary objectives
To explore the antitumor activity of panobinostat in terms of Complete Response (CR)
To assess the time to response (TTR)
To evaluate Progression Free Survival (PFS)
To assess the safety and tolerability of panobinostat
To evaluate the Overall Survival (OS) Exploratory objectives
To study the impact of pharmacogenetics in predicting the response to panobinostat 2. To study the impact of immunohistochemical patterns and patient's specific gene expression and response to panobinostat 3. To assess the correlation between "telomeric asset" and response to panobinostat

Inclusion criteria
Patient age is ≥ 18 years
Patient has an Eastern Cooperative Oncology Group (ECOG) performance status of ≤ 2
Patient has a history of DLBCL according to the WHO classification
Patient has progressive disease after receiving at least CHOP-R or CHOP-R like first line regimen, standard second line therapy (DHAP, ESHAP, ICE or similar salvage regimens) inclusive ASCT
Patient has progressive disease after receiving at least CHOP-R or CHOP-R like first line regimen and is not considered eligible for intensive salvage therapy including ASCT because of age, co-morbidities, impossibility to perform ASCT
Patient undergoes at baseline new lymphnode or other pathologic tissue biopsy for confirmation of diagnosis and biologic studies; bone marrow biopsy is not adequate for this purpose and should be performed only for staging. Patients with primary refractoriness, not eligible for intensive salvage therapy including ASCT, who performed a previous biopsy with stored frozen material 6 months or less before enrolment into the study do not have to repeat a new biopsy
Patient has at least one site of measurable nodal disease at baseline ≥ 2.0 cm in the longest transverse diameter as determined by CT scan (MRI is allowed only if CT scan can not be performed). Note: Patients with bone marrow involvement are eligible, but this criteria alone should not be used for disease measurement
Patient has the following laboratory values (labs may be repeated, if needed, to obtain acceptable values before screen fail):
Clinically euthyroid. Note: Patients are permitted to receive thyroid hormone supplements to treat underlying hypothyroidism
Written informed consent was obtained from the patient prior to any study-specific screening procedures
Patient has the ability to swallow capsules or tablets
Practice acceptable birth control.
Exclusion criteria
Patient has a history of prior treatment with a DAC inhibitors including panobinostat
Patient will need valproic acid for any medical condition during the study or within 5 days prior to the first panobinostat treatment
Patient has been treated with monoclonal antibody therapy (e.g., rituximab or anti CD-30 antibody, etc.) within 4 weeks of start of study treatment
Patient has been treated with any other anti lymphoma therapy within 3 weeks of start of study treatment
Patient is using any anti-cancer therapy concomitantly
Patient has been treated with > 5 prior systemic lines of treatment
Patient has received prior radiation therapy ≤ 4 weeks or limited field radiotherapy ≤ 2 weeks prior to start of study treatment
Patient treated with allogeneic hematopoietic stem cell transplant with active progressive cGVHD; patient has received DLI ≤ 6 weeks prior to start of study treatment; patient is planned to receive DLI
Patient has a history of another malignancy ≤ 3 years before study entry, with the exception of non-melanoma skin cancer and carcinoma in situ of uterine cervix

Patient has impaired cardiac function including any of the following:
Patient has any other clinically significant heart disease (e.g., uncontrolled hypertension)
Patient has an impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of panobinostat (e.g., ulcerative disease, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, obstruction, or stomach and/or small bowel resection)
Patient has unresolved diarrhoea ≥ grade 2
Patient has any other concurrent severe and/or uncontrolled medical condition(s) (e.g., uncontrolled diabetes mellitus, active or uncontrolled infection, chronic obstructive or chronic restrictive pulmonary disease including dyspnoea at rest from any cause) that could cause unacceptable safety risks or compromise compliance with the protocol
Patient has a known history of HIV seropositivity
Patient has active HBV hepatitis. The following categories of patients HBV positive but with non evidence of active hepatitis may be considered for the study and treated with panobinostat (see also Section 8.12 of the study protocol):
Patients with HCV active hepatitis are excluded from the study. Patient with no evidence of active hepatitis and/or advanced chronic liver disease according to liver biopsy or fibro-scan evaluation may be included into the study (see also Section 8.12 of the study protocol)
Patient is using medications that have a relative risk of prolonging the QT interval or of inducing "Torsade de Pointes", where such treatment cannot be discontinued or switched to a different medication prior to starting study drug
Women who are pregnant or breast feeding or women of childbearing potential (WOCBP) not willing to use a double method of contraception during the study and 3 months after the end of treatment. One of these methods of contraception must be a barrier method. WOCBP are defined as sexually mature women who have not undergone a hysterectomy or who have not been naturally postmenopausal for at least 12 consecutive months or had menses any time in the preceding 12 consecutive months. WOCBP must have a negative serum pregnancy test at baseline
