Clinical Trial Summary

The goal of this clinical research study is to learn the amount of posaconazole that is in the body at different time points when given to patients with leukemia. The safety of this drug will also be studied.

Objectives:

Primary:

To study the plasma pharmacokinetics of posaconazole in patients with newly diagnosed acute myelogenous leukemia (AML) or high-risk myelodysplastic syndrome (HR-MDS) undergoing induction chemotherapy or relapsed or refractory patients who will receive salvage chemotherapy.

Secondary:

To evaluate the safety of posaconazole given as prophylaxis.


Description:

Chemotherapy can lower immune system function, which can cause fungal infections to occur more easily. The standard treatment for prevention of such infections includes drugs such as voriconazole and liposomal amphotericin B that help prevent fungus from growing.

The Study Drug:

Posaconazole is designed to block the ergosterol synthesis (a part of the fungal membrane). This may help to prevent fungal infections.

Study Drug Administration:

If you are found to be eligible to take part in this study, you will take posaconazole by mouth 3 times per day. Posaconazole is a liquid. You should take the study drug after a full meal or with a liquid nutritional supplement (such as a protein shake). If you are not able to eat food, you should take it with a carbonated beverage (such as soda).

Food and Drug Diary:

You will be also be given a food and drug diary where you will write down the time you took each dose. You should also record the time eaten and describe what you ate or drank at each meal. This information will be used to find out the number of calories and amount of protein, carbohydrates, and fat you have consumed. You will be given a small bag where you can keep the drug and diary. You should return this diary after the last blood draw.

Blood Draws for Pharmacokinetics (PK) Testing:

While you are on study, blood (about 1 teaspoon each time) will be drawn for PK testing. PK testing measures the amount of study drug in the body at different time points.

- Days 1, 3, and 10, before your first dose of study drug and 3, 5, and 10 hours after the first dose of the day

- Days 2 and 4, about 24 hours after the first dose the day before

Blood (about 1 teaspoon) will also be drawn for PK testing 1 time at any of the following time points:

- Before you start a new dose of study drug, if the dose needs to be raised

- If you stop taking the study drug due to intolerable side effects or a fungal infection

Note that if you are not already in the hospital on the days of the PK blood draws, you will need to stay at the hospital for about 10 hours on these days.

Length of the Study:

You will take the study drug for up to 42 days. You will be taken off study if you experience intolerable side effects, if you develop an invasive fungal infection, or if the doctor thinks it is in your best interest.

This is an investigational study. Posaconazole is FDA approved and commercially available for the prevention of fungal infections.

Up to 25 patients will take part in the study. All will be enrolled at MD Anderson.

Eligibility Inclusion Criteria:

1.

4. Patients agree to medically approved forms of contraception

5. Patients on prior antifungal prophylaxis with voriconazole, itraconazole or fluconazole are eligible if they completed 3 days wash-out period if on voriconazole, or 14 days wash-out period if on itraconazole or 7 days wash-out period if on fluconazole

Exclusion Criteria:

1. Patients with history of anaphylaxis attributed to azole compounds

2. Patients with clinical or other evidence that indicates that they have proven or probable invasive fungal infection prior to enrollment (EORTC criteria)

3. Patients with baseline total bilirubin levels > 3 times the upper normal limits (i.e. > 3.0 mg/dl); or baseline SGPT > 5 times upper limit normal.

4. Patients receiving any medication that is contraindicated with the use of posaconazole

5. Patients with baseline creatinine levels NCI grade 3 or above (> 3.0 - 6.0 X ULN)

6. Patients with baseline QTc prolongation NCI grade 1 or above (QTc > 0.45 - 0.47 seconds).

Outcome

Type Measure Description Time frame Safety issue
Primary Maximum Observed Concentration in Plasma (Cmax) Pharmacokinetic samples were obtained on day 1, day 3 and day 10 of prophylaxis. A total of 15 samples (3 ml each sample) per participant were obtained, with thrice daily dosing planned around standard meal times. On day 1 and day 3 of prophylaxis sampling was done pre dose (0), and at 3, 5, 10 and 24 hours (±10 minutes) post dose from the time of the first dose of the day. On day 10 of prophylaxis sampling was done pre dose (0), and at 3, 5, and 10 hours (±10 minutes) post dose from the time of the first dose of the day.
Posaconazole levels were assayed by high performance liquid chromatography (HPLC). The testing range for posaconazole is from 125 - 5000 ng/ml. There are no established therapeutic ranges for posaconazole.
Pharmacokinetics: Day 1, Day 3 and Day 10 of prophylaxis.
