brentuximab vedotin and lenalidomide in patients with relapsed/ refractory t-cell lymphoma or hodgkin lymphoma

Conditions: Lymphoma, T-Cell, Cutaneous; Lymphoma, T-Cell, Peripheral; Hodgkin Lymphoma

Summary: this study is investigating the combination of brentuximab vedotin and lenalidomide in the treatment of relapsed/refractory peripheral t cell lymphoma or cutaneous t cell lymphoma or hodgkin lymphoma. it is hypothesised that lenalidomide may augment the actions of brentuximab vedotin in these patient groups. the primary objective of the study is to determine the maximum tolerated dose of the combination treatment, which can be used in subsequent studies. the study will also investigate disease response and survival. participants will receive brentuximab vedotin (once every 21 days i.e. 1 cycle) and lenalidomide (daily from day 1 -14 of each cycle) for a maximum of 48 weeks and will be followed for a subsequent 6 months after the end of treatment.


Eligibility criteria:
inclusion criteria: 1. male or female patients of 18 years or older. 2. patient must have a diagnosis of a cd30+ hodgkin lymphoma or cd30+ peripheral t-cell lymphoma. patients with either hodgkin lymphoma or t-cell lymphoma must have expression of cd30 in ≥10% of lymphoma cells. patients with ctcl will be considered for inclusion even if cd30 immunohistochemical staining with berh2 antibody is low or negligible (\<10%). 1. peripheral t-cell lymphoma: patients must be considered relapsed or refractory after at least one prior chemotherapeutic regimen or be considered by the investigator to be not suitable for chemotherapy 2. cutaneous t-cell lymphoma: patients must be relapsed or refractory to one prior systemic therapy or be considered by the investigator to be not suitable for chemotherapy 3. patients with hodgkin lymphoma and one of the following: i. relapsed or refractory after at least 2 prior chemotherapy-containing regimens ii.considered unsuitable for chemotherapy 3. voluntary written informed consent must be given before performance of any study- related procedure. 4. female patient is either post-menopausal for at least 1 year before the screening visit or surgically sterile or if of childbearing potential, agree to practice 2 effective methods of contraception, at the same time, from the time of signing the informed consent through 6 months after the last dose of study drug, or agrees to completely abstain from heterosexual intercourse. 5. male patients, even if surgically sterilized, (i.e., status post vasectomy) agree to practice effective barrier contraception during the entire study period and through 6 months after the last dose of study drug, or agrees to completely abstain from heterosexual intercourse. 6. performance status of ecog ≤2. 7. clinical laboratory values as specified below. blood tests must be within 10 days of patient registration: * absolute neutrophil count \>1.5 x109/l, or \>1.0 x109/l in the setting of known marrow involvement by tumour. * platelet count ≥75x109/l. * total bilirubin must be \< 1.5 x the upper limit of the normal (uln) unless the elevation is known to be due to gilbert syndrome. * alt or ast must be \< 2.5 x the upper limit of the normal range. ast or alt may be elevated up to 5 times the uln if their elevation can be reasonably ascribed to the presence of haematologic/solid tumor in liver. * serum creatinine must be \ 40 ml/minute. * haemoglobin must be ≥ 80g/l. 8. patients must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy (except alopecia) prior to registration. exclusion criteria: 1. female patients who are both lactating and breast-feeding or have a positive serum pregnancy test during the screening period or a positive pregnancy test on planned cycle 1, day 1 prior to first dose of study drug. 2. any serious medical or psychiatric illness that could, in the investigator's opinion, potentially interfere with the completion of treatment according to the protocol. 3. symptomatic neurologic disease compromising normal activities of daily living or requiring medication/s, including signs or symptoms of progressive multifocal leucoencephalopathy (pml). 4. any sensory or motor peripheral neuropathy greater than or equal to grade 2 at registration. 5. known history of any of the following cardiovascular conditions 1. new york heart association (nyha) class iii or iv heart failure (see appendix 18.1). 2. evidence of current uncontrolled cardiovascular conditions, including cardiac arrhythmias, congestive heart failure (chf), angina, or electrocardiographic evidence of acute ischemia or active conduction system abnormalities. 3. a left-ventricular ejection fraction \<50% 6. any active systemic viral, bacterial, or fungal infection requiring systemic intravenous antibiotics or systemic antifungal therapies within 2 weeks prior to registration. 7. patients that have not completed any prior treatment chemotherapy and/or other investigational agents within at least 5 half-lives of last dose of that prior treatment. 8. known hypersensitivity to recombinant proteins, murine proteins, or to any excipient contained in the drug formulation of brentuximab vedotin or lenalidomide. 9. known human immunodeficiency virus (hiv) positive. 10. known hepatitis b surface antigen (hbsag)-positive, or known or suspected active hepatitis c infection. patients who are hepatitis b core antibody positive with no evidence of active disease, i.e. hbsag negative/ negative hepatitis b viral load, will still be considered eligible for inclusion, but must receive viral suppressive therapy for the duration of the trial. 11. active systemic malignancy likely to require treatment within the next two years, or previous diagnosis of another malignancy with residual disease. patients with non-melanoma skin cancer or carcinoma- in-situ of any type are not excluded if they have undergone complete resection. 12. previous exposure to brentuximab vedotin.
