a phase i study of alisertib + r-epoch for treatment of myc-positive aggressive b-cell lymphomas

Conditions: Diffuse Large B-cell Lymphoma; Follicular Lymphoma; Burkitt Lymphoma

Summary: this phase i/ib study is designed to establish the safety and maximum tolerated dose (mtd, which will also be the recommended phase ii dose (rp2d)) of the aurora kinase a inhibitor alisertib when combined with dose-adjusted (da)-r-epoch (rituximab, etoposide, doxorubicin, vincristine, cyclophosphamide and prednisone) in patients with cd20-positive diffuse large b-cell lymphoma (dlbcl), transformed follicular lymphoma or burkitt lymphoma positive for myc gene rearrangement (myc+). filgrastim or peg-filgrastim is also included with each cycle of r-epoch. once we identify the mtd, an expansion cohort limited to the myc+ dlbcl population will be opened to further characterize clinical activity and safety. secondary objectives include estimates of complete response rate (cr) and progression free survival (pfs). we will also explore for associations between baseline kinome signatures and/or rna sequencing and cr, and identify differential kinome and transcriptome prior to and during treatment.

(world health organization, global alert and response (gar), hepatitis b (who.int/csr/disease/hepatitis/ whocdscsrlyo20022/en/index4.html) * patient agrees to consume no more than 1 standard unit of alcohol per day during the study and for 30 days from the last dose of alisertib. a standard unit of alcohol is defined as a 12 oz beer (350 ml), 1.5 oz (45 ml) of 80-proof alcohol, or one 6-oz (175 ml) glass of wine. * women of childbearing potential (wocbp) must have negative pregnancy test within 7 days prior to d1 of treatment * female subjects must be: * post-menopausal for at least one year before the screening visit, or * surgically sterilized, or * willing to use an acceptable method of birth control (ie, a hormonal contraceptive, intra-uterine device, diaphragm with spermicide, condom with spermicide, or abstinence) for the duration of the study. * male subject, even if surgically sterilized (ie, status post-vasectomy), agrees to: * use an acceptable method for contraception (effective barrier contraception or: * completely abstain from heterosexual intercourse) during the entire study treatment period through 4 months after the last dose of alisertib. * ability to swallow oral medications * as determined by the enrolling physician or protocol designee, ability of the patient to understand and comply with study procedures for the entire length of the study * sufficient data to calculate the international prognostic index (ipi) score at baseline: * age * stage of disease * ldh * ecog performance status * number of extranodal sites * voluntary written informed consent before performance of any study-related procedure not part of normal medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to future medical care. * adequate left ventricular function with ejection fraction ≥ 40% by echocardiogram or muga scan. exclusion criteria * cns involvement of dlbcl * major surgery within 4 weeks prior to entry * receiving any other concurrent cytotoxic, biologic agent(s) or investigational agent ; note: concurrent intrathecal chemotherapy for cns prophylaxis allowed per institutional standards * receipt of investigational drugs within 14 days before d1 of alisertib * prior administration of an aurora a kinase-targeted agent, including alisertib * patients with a "currently active" second malignancy other than non-melanoma skin cancers, non-invasive bladder cancer, "low risk" adenocarcinoma of the prostate and carcinoma in situ of the cervix. patients are not considered to have a "currently active" malignancy if they have completed therapy and are free of disease for ≥ 3 years. * treatment with clinically significant enzyme inducers, such as the enzyme-inducing antiepileptic drugs phenytoin, carbamazepine or phenobarbital, or rifampin, rifabutin, rifapentine or st. john's wort within 14 days prior to the first dose of alisertib and during the study. * radiation therapy to more than 25% of the bone marrow (note: whole pelvic radiation is considered to be over 25%) * prior allogeneic bone marrow or organ transplantation * known gi disease or gi procedures that could interfere with the oral absorption or tolerance of alisertib;
