Clinical trial: Aurora A Kinase Inhibitor MLN8237 in Treating Patients With Unresectable Stage III-IV Melanoma

Summary: RATIONALE: Aurora A kinase inhibitor MLN8237 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
  PURPOSE: This phase II trial is studying how well Aurora A kinase inhibitor MLN8237 works in treating patients with unresectable stage III-IV melanoma

Detailed description: PRIMARY OBJECTIVES:
  I. Estimate the degree of clinical benefit based primarily on objective clinical responses with AURKA inhibitor, MLN8237 in patients with metastatic melanoma in a phase II, 2-stage trial for patients with measurable unresectable disease.
  SECONDARY OBJECTIVES:
  I. Assess the progression-free survival and overall survival for all patients enrolled.
  II. Define toxicities due to MLN8237 and characterize their severity both over a short and prolonged duration of administration.
  III. In patients entered on stage 1 of clinical trial whenever possible through pre-treatment biopsy and post-treatment surgical specimen, we will define target inhibition at tumor sites based on: AURKA autophosphorylation (AURKAThr288/AURKA), intra-tumoral drug levels, expression of p53-induced NOXA and PUMA expression, TPX2, (by IHC) and TUNEL as markers of apoptosis, cell cycle changes (mitotic index), proliferation (Ki-67), aneuploidy, and AKT phosphorylation.
  IV. All phase II trial patients enrolled on the 2nd stage will have pre- and post-treatment biopsies (post-day 7+/-3 days) to demonstrate that AURKA is inhibited based on autophosphorylation AURKA/AURKA^Thr 288, Histone H3 (at S10) phosphorylation, AKT phosphorylation, cell cycle changes (mitotic index), TPX2 (by IHC), proliferation (Ki-67), aneuploidy, and p53-induced NOXA and PUMA expression, and TUNEL as markers of apoptosis.
  V. Demonstrate any correlation between MLN8237 induced target inhibition at tumor sites and clinical benefit of MLN8237.
  VI. Characterize the de novo molecular mutational profile of the melanomas from all patients entered using a developed SNaPshot assay for melanoma in addition loss of regulatory proteins (i.e., PTEN), DNA copy numbers and gene expression (AURKA), and autophosphorylation of AURKA as well as AURKA localization by IHC.
  OUTLINE: Patients receive oral Aurora A kinase inhibitor MLN8237 every 12 hours on days 1-7. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
  After completion of study treatment, patients are followed up every 3 months for 1 year and then every 6 months for 5 years.

  4. INR<1.5,
  5. Creatinine < 1.5x institutional upper limit of normal (IULN), and/or an adequate renal function as defined by: Calculated creatinine clearance must be ≥ 40 mL/minute (Cockcroft-Gault).
  6. Aspartate and alanine aminotransferase < 2.5 x institutional upper limit of normal (IULN), bilirubin < 1.5x IULN
  -  Female subject is either post-menopausal or surgically sterilized or willing to use an acceptable method of birth control (i.e., a hormonal contraceptive, intra-uterine device, diaphragm with spermicide, condom with spermicide, or abstinence) for the duration of the study and for 3 months after the completion of the study. Male subject agrees to use an acceptable method for contraception for the duration of the study and for 3 months after the completion of the study
  -  A single regimen of prior chemotherapy for metastatic melanoma is allowed. Patients also may have received other immunotherapy or biologic therapy (including kinase inhibitors, antibodies to checkpoints CTLA4, PD1, PDL1, etc.) for metastatic melanoma and there is a limit of three therapy regimens
  -  No prior Aurora kinase inhibitor
  -  Completed prior chemotherapy a minimum of 4 weeks previously (6 weeks for BCNU and/or mitomycin C), 4 weeks for prior immune therapy, 6 weeks for antibodies to checkpoints CTLA4, PD1, PDL1, etc, and 2 weeks for targeted agents (i.e. inhibitors of MEK, BRAF, Akt, PI3K, mTORC1/2) or localized radiation therapy. All treatment All treatment related toxicity must have resolved to grade 2 or less or to a baseline level as well.
  -  Patients cannot receive concomitant radiation therapy at enrollment. While on protocol limited palliative radiotherapy extending over a small bone marrow field (10%) is allowed.
  -  Patients with brain metastases are allowed only if they are off systemic corticosteroids and stable for a minimum of 8 weeks.
  -  Patients must be 18 years of age or above and voluntary written informed consent must be obtained 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.
  -  Subject must be able to take oral medication and to maintain a fast as required before and after MLN8237 administration.
  Exclusion Criteria
