This is a phase I/II study to find the highest dose of hydroxychloroquine that can be given safely with itraconazole in patients with advanced platinum-resistant epithelial ovarian cancer. The study will also determine the safety, tolerability, and initially determine whether the combination is useful in the treatment of patients with advanced platinum-resistant epithelial ovarian cancer.

Primary Outcome Measures:
  • Maximum tolerated dose of hydroxychloroquine [ Time Frame: 5 years ]
    Highest dose of hydroxychloroquine that is safe and tolerable that can be given in combination with itraconazole.

Secondary Outcome Measures:
  • Median progression-free survival [ Time Frame: 5 years ]
    Median duration of time from start of treatment to time of progression or death.

  • Overall response rate [ Time Frame: 5 years ]
    Proportion of patients achieving complete response or partial response.

Estimated Enrollment: 52
Anticipated Study Start Date: May 1, 2017
Estimated Study Completion Date: October 1, 2022
Estimated Primary Completion Date: May 1, 2022 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Hydroxychloroquine and Itraconazole

Hydroxychloroquine, orally (by mouth), at a dose of 100 mg, 200 mg, 400 mg, or 600 mg, twice a day, every day.

Itraconazole, orally (by mouth) at 300 mg, twice a day, every day.

Drug: Hydroxychloroquine
Hydroxychloroquine is approved/used for the treatment of rheumatoid arthritis, and discoid and systemic lupus erythematosus, as well as suppressive treatment and treatment of acute attacks of malaria.
Drug: Itraconazole
Itraconazole is approved and used for the treatment of certain systemic fungal infections.


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Aged 18 years or older.
  • Histologically or cytologically confirmed epithelial ovarian cancer.
  • Platinum-resistant or refractory disease defined as a radiological or clinical progression less than six months after having finished platinum-based chemotherapy.
  • ECOG performance status equal to or less than 1.
  • Have clinically or radiographically documented measurable disease.
  • All systemic therapy must have been completed 4 weeks or greater prior to enrollment with radiologic evidence of radiological disease progression.
  • Life expectancy should be more than 3 months.
  • Receiving any medications or substances that are inhibitors or inducers of CYP3A4 are ineligible.
  • Acceptable laboratory requirements within 7 days prior to enrollment
  • Treated and asymptomatic brain metastases are eligible. Patients that received palliative radiation (for brain metastases) are eligible if they have been asymptomatic for at least 2 weeks with use of maintenance steroid therapy, and last received radiation at least 4 weeks prior to start of therapy.
  • Have the ability to understand and willing to sign a written informed consent document.

Exclusion Criteria:

  • Have not recovered (grade 1 or less) from adverse events related to previous treatments are excluded with the exception of alopecia and lymphopenia. Peripheral sensory neuropathy must be at grade 2 or less.
  • Have any other prior malignancy from which the patient has been disease free for less than 3 years, with the exception of adequately treated and cured basal or squamous cell skin cancer, superficial bladder cancer, carcinoma in situ of any site or any other cancer.
  • History of allergic reactions attributed to compounds of similar chemical or biologic composition to itraconazole or hydroxychloroquine.
  • Known G6PD deficiency due to the risk of hemolytic anemia with the use of hydroxychloroquine.
  • Known retinopathy due to the risk of worsening retinopathy with hydroxychloroquine.
  • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic or asymptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
  • Chronic Hepatitis B or hepatitis C infections should be excluded because of potential effects on hepatic function and/ or drug interactions.
  • Human Immunodeficiency Virus (HIV) infection.
  • Already have a clinical indication for treatment with itraconazole (e.g. chronic candidiasis or other fungal infection) or hydroxychloroquine (e.g. lupus).
