Peptide Receptor Radionuclide Therapy With 90Y-Dotatoc in Relapsed/Refractory Diffuse Large B Cell and Mantle Cell Lymphomas (itTRIOlym)

This is an interventional treatment trial for DLBCL focused on measuring Relapsed/refractory diffuse large b cell, Relapsed/refractory mantle cell lymphomas, DLBCL, MCL, 90Y-DOTATOC, SSR-positive tumour Read More

Inclusion Criteria:

1. Male or Female, aged >18 years.
2. Histologically confirmed relapsed or refractory DLBCL or MCL not suitable to other treatments.
3. Patients with documented disease will be admitted to therapeutic phase only if the diagnostic PET/CT with 68Ga-DOTATOC images demonstrate a significant uptake in the tumour (SSR-positive tumour).
4. Patients must have at least one bidimensional measurable lesion with long axis > 15 mm at CT scan (MRI is allowed only if CT scan cannot be performed), according to Cheson Criteria.
5. Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2.
6. Life expectancy of at least 3 months.
7. Adequate cardiac function as assessed at echocardiography and ECG.
8. Conserved hematological, liver and renal parameters, and in particular: haemoglobin >= 9 g/dL, absolute neutrophil count (ANC) >= 1.5 x 109 /L, platelets >= 100 x 109 /L, bilirubin ≤1.5 X UNL (upper normal limit), Alanine aminotransferase (ALT) <2.5 X UNL (< 5 X UNL in presence of liver metastases), creatinine < 2 mg/dL
9. Patients must not have received other treatments with radiopeptides (e.g. 111In-pentetreotide, 177Lu-DOTATATE, 131I-MIBG).
10. If female of childbearing potential, agreement to use adequate contraceptive methods (e.g., oral contraceptives, condoms, or other adequate barrier controls, intrauterine contraceptive devices, or sterilization) beginning at screening visit and continuing until 3 months following last treatment with study drug. Negative serum pregnancy test for females of childbearing potential within 7 days of starting treatment.

Exclusion Criteria:

1. Pregnancy/breastfeeding (a pregnancy test not older than 7 days is mandatory).
2. Bone marrow invasion > 25 %.
3. Other concomitant neoplasm (excluding in situ basaliomas and radically treated cervical cancers); subjects must be free from other neoplasms at least 3 years. All acute toxic effects of any prior therapy (including surgery radiation therapy,chemotherapy) must have resolved to a grade <= 1 according to National Cancer Institute Common Terminology Criteria for Adverse Events Version 4.0 (CTCAE).
4. Evidence of myelodysplastic syndrome or other hematologic diseases
5. Patients treated with chemotherapy and therapeutic radiotherapy within 4 weeks.
6. Participation in another clinical trial with any investigational agents within 30 days prior to study screening.
7. Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
8. Positive serology for Hepatitis B (HB) defined as a positive test for Hepatitis B surface antigen (HbsAg). In addition, if negative for HBsAg but Hepatitis B core antibody (HBcAb) positive (regardless of HBsAb status), a hepatitis B virus (HBV) DNA test will be performed and if positive the subject will be excluded. Any patient with HBcAb positivity will receive anti viral prophylaxis during the study, according to the procedures suggested by local Hepatology service.
9. History of allergic reactions attributed to compounds of similar chemical or biologic composition.
10. Previous autologous stem cell transplant in the last 2 months.
