Prostate Cancer Clinical Trials

Cabozantinib (XL184) for Advanced Malignancies
A Randomized Discontinuation Study of XL184 in Subjects With Advanced Solid Tumors
Status Conditions Phase Study ID
Closed Advanced Solid Tumors Phase II NCT00940225
Summary

The purpose of this study is to determine whether or not Cabozantinib (XL184) demonstrates anti-tumor activity in selected tumor types under a randomized discontinuation trial (RDT) design. Subjects who have responded to study drug after 12 weeks of open-label XL184 administration will continue to take XL184. Subjects who are clearly progressing will discontinue study treatment and subjects who demonstrate stable disease will be randomized to either XL184 or placebo. For individual patients, once disease progression is observed, the blind will be broken and subjects who were randomized to placebo will be offered the option to receive open-label XL184. Subjects who progressed while taking XL184 will discontinue study treatment.

Emerging data may support enrollment in an open-label, non-randomized expansion cohort (NRE). Subjects with prostate and ovarian cancers will enroll in these expansion cohorts. Other tumor types may similarly be expanded, as supporting data emerges.

Criteria

Inclusion Criteria:

  • The subject has a cytologically or histologically and radiologically confirmed, advanced, recurrent, or metastatic solid tumor of the nine types listed below:

    • Castration-Resistant Prostate Cancer (CRPC)
    • Hepatocellular Carcinoma (HCC)
    • Gastric or Gastroesophageal Junction Cancer
    • Melanoma
    • Small Cell Lung Cancer (SCLC)
    • Ovarian cancer, primary peritoneal or fallopian tube carcinoma

    • Non-Small Cell Lung Cancer (NSCLC)
  • Certain requirements for prior therapies may apply
  • The subject has documented progressive disease at screening
  • Subjects having any tumor type of other than CRPC must have at least one lesion that is not within a previously irradiated field and is measurable on CT or MRI scan
  • The subject has recovered to baseline or CTCAE ≤ Grade 1 from toxicities related to prior treatment (some exceptions apply)
  • The subject is ≥ 18 years old on the day of consent
  • Tissue samples from archival or fresh tissue, or a tissue block of the subject's tumor
  • The subject has an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
  • The subject has adequate organ function
  • The subject is capable of understanding and complying with the protocol requirements and has signed the informed consent document
  • Sexually active fertile subjects (male and female), and their partners, must agree to use medically accepted methods of contraception during the course of the study and for 3 months after the last dose of the study drug(s)
  • Female subjects of childbearing potential must have a negative pregnancy test at screening
Exclusions (conditions that would prevent participation in this study)

Exclusion Criteria:

  • The subject has experienced clinically-significant hematemesis or hemoptysis of >0.5 teaspoon of red blood, or other signs indicative of pulmonary hemorrhage within 3 months before the first dose of study treatment
  • The subject has a cavitating pulmonary lesion(s) or a pulmonary lesion abutting or encasing a major blood vessel

  • The subject requires concomitant treatment, in therapeutic doses, with anticoagulants such as warfarin or Coumadin-related agents, heparin, thrombin or FXa inhibitors, and antiplatelet agents (low-dose aspirin (≤81 mg/day), low-dose warfarin (≤1mg/day, and prophylactic low molecular weight heparin (LMWH) are permitted)
  • The subject has uncontrolled, significant intercurrent illness
  • The subject is unable to swallow capsules
  • The subject is pregnant or breastfeeding
  • The subject has a previously-identified allergy or hypersensitivity to components of the study treatment formulation
  • The subject is unable or unwilling to abide by the study protocol or cooperate fully with the investigator or designee
  • The subject has had another diagnosis of malignancy requiring systemic treatment within the last two years, unless non-melanoma skin cancer, in-situ carcinoma of the cervix, or superficial bladder cancer
