Oral Posaconazole Three Times Per Day vs Weekly High Dose Amphotericin B Lipid Complex (ABLC)

August 22, 2016 updated by: M.D. Anderson Cancer Center

Phase III Clinical Trial of Oral Posaconazole 3 Times/Day vs Weekly High Dose Amphotericin B Lipid Complex (ABLC) for Prevention of Invasive Fungal Infections In Patients With Hematologic Malignancies & Hematopoietic Stem Cell Transplant

The objective of this study is to compare the safety and efficacy of ABLC versus oral Posaconazole in the prevention of invasive fungal infections in high risk patients with hematologic malignancies or hematopoietic stem cell transplant.

Primary objective is to demonstrate the low toxicity rate and low rate of invasive fungal infections associated with ABLC or Posaconazole prophylaxis.

Secondary objective will be to compare the cost effectiveness of these two prophylactic regimens.

Detailed Description

The Study Drugs:

ABLC is an antifungal drug that is commonly used to treat and/or prevent a variety of serious invasive fungal infections (IFIs). In this study, ABLC will be used for IFI prevention.

Posaconazole is a newer antifungal drug that is commonly used to prevent serious IFIs.

Study Groups:

If you are found to be eligible to take part in this study, you will be randomly assigned (as in the toss of a coin) to receive either posaconazole or ABLC. You will have an equal chance (50/50) of being assigned to either group. You and your study doctor will know which group you are in.

Study Drug Administration:

If you are assigned to the Posaconazole Group, you will take posaconazole 3 times a day by mouth for up to 6 weeks (Days 1-42). The study doctor will advise you about taking it with fatty meals and/or nutritional supplements.

If you are assigned to the ABLC Group, you will receive ABLC once a week by vein over 4-6 hours, for up to 6 weeks (from Day 1 through Day 42). If the creatinine level increases, the dose will be divided into 2 doses per week. The drug may be given in the hospital (if you are admitted to the hospital before or during the study) or at an outpatient treatment center.

Study Visits:

Once a week from Day 1 to Day 42, you will have the following procedures performed:

  • Blood (about 1 tablespoon) will be drawn for routine tests.
  • You will be asked about any medications and treatments you may be receiving.
  • You will be asked about any IFI symptoms that may have developed. You will also be asked about any side effects that may have occurred since your last visit. (You should contact the study doctor and/or study staff right away, if at any time you feel you have had a side effect.)

You may have certain routine diagnostic tests performed at any time in the study, if necessary to confirm you do not have an IFI. These tests may include blood collection (about 1 tablespoon), scans, skin tissue biopsy, and/or bronchoscopy.

Length of Study:

You will receive study treatment for up to 6 weeks (42 days). If you develop an IFI or any intolerable side effects, you will be taken off study early. You may also be taken off study if your neutrophil (a type of white blood cell) counts recover.

End-of-Treatment Visit:

Your End-of-Treatment visit will be on the last day you received the study drug (at most, 42 days after you started). The following procedures will be performed.

  • Blood (about 1 tablespoon) will be drawn for routine tests.
  • You will have a physical exam, including measurement of vital signs.
  • If the study doctor and/or your primary doctor thinks you may have an IFI, routine diagnostic tests may be performed.

Follow-up Visit:

Your follow up visit will be completed 7 - 14 days after your end-of-treatment visit. The following procedures will be performed:

  • You will be checked for any signs of IFI.
  • If your doctor suspects you have an IFI, a scan (such as an x-ray or CT scan) and/or bronchoscopy may be performed.
  • You will be asked about any medications and treatments you may be receiving, and any side effects you may have had.
  • Your vital signs will be checked, and a physical exam may be performed.
  • Blood (about 1 tablespoon) will be drawn for routine tests.
  • An ECG may be performed.

This is an investigational study. ABLC and posaconazole are FDA approved and commercially available for the treatment and prevention of IFIs. Posaconazole is FDA approved for the way it is being used in this study. The study dose and study schedule for ABLC, however, is considered experimental. Currently, this dose and schedule for ABLC is being used in research only.

Up to 100 patients will take part in this study. All will be enrolled at M. D. Anderson.

Description

Inclusion Criteria:

  1. Subjects: 18 years of age or above.
  2. Any allogeneic hematopoietic stem cell transplant (HSCT) patient who is at risk of invasive fungal infection (IFI) within 6 months of the transplant will be eligible for the study according to HSCT institutional anti-fungal prophylaxis guidelines.
  3. Subjects must be willing to give written informed consent and able to adhere to dosing and study visit schedule.
  4. Female subjects of childbearing potential must have a negative serum pregnancy test (beta-human chorionic gonadotropin [hCG]) at Baseline or within 96 hours before the start of study drug.
  5. Female subjects of childbearing potential must agree to use a medically accepted method of contraception prior to screening, while receiving protocol-specified medication, and for 30 days after stopping the medication. Acceptable methods of contraception include condoms with/without a spermicidal agent, diaphragm or cervical cap with spermicide, medically prescribed IUD (intrauterine device), oral/injectable hormonal contraceptive, surgical sterilization (e.g. hysterectomy/tubal ligation).

  2. Subjects who have taken the following drugs: terfenadine, cisapride, primazide, and ebastine; that are known to interact with azoles and that may lead to life-threatening side effects, within 24 hours before study drug administration.

Subjects who have taken the following drugs: cimetidine, rifampin, carbamezapine, phenytoin, rifabutin, barbiturates, isoniazid, and vinca alkaloids (vincristine, vinblastine); that are known to lower the serum concentration/efficacy of azole antifungal agents, within 24 hours before study drug administration.
  4. Subjects with a history of hypersensitivity or idiosyncratic reactions to azole agents or Amphotericin B.
