About this study

Official title: The Effect of Glucose Level and Diabetes Mellitus on the Plasma Minimum Steady-state Concentration Ctrough of Olaparib in Patients With Ovarian Cancer

Monitored therapy of olaparib concentrations in the blood of diabetic population probably will assess the need for individual dosing of the drug.

The project concerns on the monitored therapy of olaparib in a population of patients with DM, hyperglycemia and normal glucose level.

Currently, there are no studies assessing the effect of comorbidities and of the administered drugs on the pharmacokinetics of olaparib.

Read the detailed description

The research is conducted at the Poznan University of Medical Sciences, and the Poznan, Poland with the approval from the Bioethics Committee, University of Medical Sciences, Poznan, Poland (697/20). The subjects of the research: the C through of olaparib in the patients with ovarian cancer who received olaparib The patients included in the study if they met the following criteria: treatment with olaparib above four days, age >18 years; no history of allergy to olaparib. The chief criteria for exclusion included allergy to olaparib, age under 18 years, status of the patient which do not allowed the patient to continue the study.

Administration and blood sampling The patients with an ovarian cancer treated with olaparib (tablets in dose 300mg/12h, 250mg/12h, 200 mg/12h or capsules 400mg/12h, 200mg/12h, 100 mg/12h).

Blood samples (2 mL) collected at steady state before morning drug administration. The blood samples transferred into heparinised tubes and centrifuged at 2880 g for 10 min at 4 °C. Next the plasma transferred to propylene tubes and stored at - 20 °C until analysis.

Assays The concentrations of olaparib in plasma assayed using the high-performance liquid chromatography (HPLC) method with ultraviolet (UV) detection. The method validated according to European Medicines Agency guideline. The method validation confirmed good precision (CV% <15%), accuracy (92.3-115.0%) and linearity (r=0.9994) in the range of 100-4000 ng/mL.

The severity of olaparib adverse effects assessed by CTCAE (Common Terminology Criteria for Adverse Events) v.5.0 scale.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. correlation between glucose level and C through.olaparib in the blood of the patients with ovarian cancer

    There is idea to check the correlation of C through of the olaparib taken by the patients with diabetes melitus and ovarian cancer and the correlation of C through and glucose of the patients with hyperglycemia diagnosed during olaparib treatment

    Measured: through study completion, an average of 1 year

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 18 Oct 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Poland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does the primary outcome measure?

correlation between glucose level and C through.olaparib in the blood of the patients with ovarian cancer (time frame: through study completion, an average of 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05081765, which also lists 13 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
