Brief Summary

The receptor tyrosine kinase AXL is a pathway that plays a crucial role in metastasis and chemoresistance. Overexpression of AXL has been associated with metastasis, recurrence, and chemoresistance in various cancer including ovarian cancer\[16, 17\]}. Targeting AXL is an attractive approach because it is overexpressed among patients with epithelial ovarian cancer and strongly associated with advanced stages, high grade cancer and shorter median survival time. AVB-S6-500 is a potent AXL inhibitor by binding to the ligand Gas6. Pre-clinical studies found that AVB-S6-500 was efficacious in ovarian cancer xenograft tumor models. Interventions which would increase the proportion of patients achieving pCR in this patient population could impact survival favorably and are of interest for study.

Outcome Measures

Primary Outcomes (7)

  • Maximum tolerated dose (MTD) of AVB-S6-500 in combination with and following conventional chemotherapy and maintenance

    * The study will employ the Bayesian optimal interval design (BOIN) to find the MTD. * Select as the MTD the dose for which the isotonic estimate of the toxicity rate is closest to the target toxicity rate. If there are ties, select the higher dose level when the isotonic estimate is lower than the target toxicity rate and select the lower dose level when the isotonic estimate is greater than or equal to the target toxicity rate.

    Completion of the enrollment and treatment of all patients (estimated to be approximately 26 months)

    -Hematologic DLT any of the following that occur during the 1st cycle (C) that are possibly (pos), probably (prob), or definitely (def) related to the study treatment: * Grade (Gr.) 4 neutropenia or thrombocytopenia \> 7 day * Febrile neutropenia w/ temp \> 38.5 °C * Gr. 4 anemia or Gr. 4 thrombocytopenia which requires transfusion therapy on more than 2 occasions in 7 days * Gr. thrombocytopenia w/ bleeding Non-hematologic DLT is any pos, prob, or def related Gr. 3 or grade 4 non-hematologic toxicity that occurs during C1 with the following exceptions: * Gr. 3/4 nausea/vomiting/anorexia that returns to Gr. 1 prior to the start of C2 * Gr. 3 nausea/vomiting or diarrhea \< 72 hours with adequate antiemetic and other supportive care starting with C2 * Gr. 3 triglycerides will only be considered a DLT for patients who have grade 3 in spite of appropriate lipid lowering drug therapy * Gr. 3 rash (patients who have received 2 weeks of supportive care treatment w/ no improvement)

    Through completion of 1st cycle for all patients (estimated to be 13 months)

  • Tolerability of the combination at the MTD of AVB-S6-500 assessed in combination with standard neoadjuvant chemotherapy as measured by treatment discontinuation

    Through completion of treatment (estimated to be 14 months)

  • Tolerability of the combination at the MTD of AVB-S6-500 assessed in combination with standard neoadjuvant chemotherapy as measured by number of dose interruption/reductions

    Through completion of treatment (estimated to be 14 months)

  • Tolerability of the combination at the MTD of AVB-S6-500 assessed in combination with standard neoadjuvant chemotherapy as measured by use of supportive therapies

    Through completion of treatment (estimated to be 14 months)

  • Tolerability of the combination at the MTD of AVB-S6-500 assessed in combination with standard neoadjuvant chemotherapy as measured by number of hospital admissions

    Through completion of treatment (estimated to be 14 months)

  • Tolerability of the combination at the MTD of AVB-S6-500 assessed in combination with standard neoadjuvant chemotherapy as measured by number of deaths

    Through completion of treatment (estimated to be 14 months)

Secondary Outcomes (5)

  • Objective clinical response (cOR) of AVB-S6-500 in combination with and following conventional chemotherapy and maintenance

    At the time of interval debulking (approximately 9-12 weeks)

  • Pathological complete response (pCR) at the time of interval debulking surgery of AVB-S6-500 in combination with and following conventional chemotherapy and maintenance

    At the time of interval debulking (approximately 9-12 weeks)

  • Progression-free survival (PFS) at 1 year after debulking surgery of AVB-S6-500 in combination with and following conventional chemotherapy and maintenance

    1 year after debulking surgery (approximately 64 weeks)

  • Progression-free survival (PFS) at 2 years after debulking surgery of AVB-S6-500 in combination with and following conventional chemotherapy and maintenance

    2 years after debulking surgery (approximately 116 weeks)

  • Overall survival (OS) by long-term follow-up of AVB-S6-500 in combination with and following conventional chemotherapy and maintenance

    5 years after completion of treatment (approximately 74 months)

  • Adenocarcinoma not otherwise specified (NOS)
  • Disease must be considered "bulky" by the clinician (unresectable via primary debulking surgery) and in need of neoadjuvant chemotherapy prior to debulking surgery. This assessment of unresectability can be made via imaging or laparoscopic scoring.
  • Must have pre-treatment tumor tissue available or agree to tissue collection from IR-guided biopsy.
  • Any hormonal therapy directed at the malignant tumor must be discontinued at least one week prior to registration. Continuation of hormone replacement therapy is permitted.
  • At least 18 years of age.

  • A history of other malignancy ≤ 3 years previous with the exception of basal cell or squamous cell carcinoma of the skin which were treated with local resection only. Patients with concomitant endometrial cancer diagnosed at the time of the ovarian cancer are allowed to participate if the endometrial cancer is FIGO stage IB or less.
  • Currently receiving any other (non-study) cytotoxic chemotherapy.
  • Currently receiving any other investigational agents or has received an investigational agent within 4 weeks of start of study treatment.

  • Abnormal gastrointestinal function (nausea or vomiting). This includes GI obstruction or bleeding or signs/symptoms thereof within 3 months of study enrollment. Patients with a history of abdominal fistula will be considered eligible if the fistula was surgically repaired or has healed, there has been no evidence of fistula for at least 6 months, and patient is deemed to be at low risk of recurrent fistula.
  • Significant cardiac disease history including:
  • Clinically significant atrial or ventricular arrhythmias requiring treatment
  • Medically controlled congestive heart failure
  • Significant angina or clinically and/or electrocardiographically documented myocardial infarction within the past year
  • Clinically significant valvular disease
  • Non-healing wound, ulcer, or bone fracture.
