About this study

Official title: A Single-center, Open-Label, Drug Interaction Study to Determine the Effects of Apatinib on the Metabolism of CYP3A4/5 and CYP2C9 Probe Drugs in Patients With Solid Tumors

Apatinib, an oral inhibitor of vascular endothelial growth factor receptor 2(VEGFR-2), inhibits multiple cytochrome P450 (CYP450) enzymes in vitro. This study in patients with advanced cancer evaluated the effect of Apatinib on CYP450 function by comparing the pharmacokinetics of CYP-specific probe drugs in the presence and absence of Apatinib. The probes used included Nifedipine (CYP3A specific), warfarin (CYP2C9 specific).

Read the detailed description

This open-label study consists of a drug interaction phase that (part A) and a drug-continuation phase (part B). Patients will receive CYP450-probe drugs, and PK assessments will be performed before apatinib-administration and aſter once-daily administration of apatinib for 5 days (the predicted time point when steady-state plasma apatinib concentrations will have been achieved).

Being tested
Apatinib, Nifedipine GTIS, Warfarin Potassium

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ApatinibDrug

    Apatinib at a dosage of 750mg will be administered daily from day 9 of phase A

  • Nifedipine GTISDrug

    Also called Nifedipine

    Nifedipine at a dosage of 30mg will be administered at day 1 and day 14 of phase A

  • Warfarin PotassiumDrug

    Also called warfarin

    Nifedipine at a dosage of 3mg will be administered at day 3 and day 16 of phase A

Study groups in NCT03245307
Study groupRoleWhat they receive
TreamentExperimentalIn phase A, subjects receiving a single 30 mg oral dose of Nifedipine controlled-release tablets and wash-out for 2 days,a single 3 mg oral dose of warfarin tablets and wash-out for 12 days, then apatinib 750 mg once daily with a single 30 mg oral dose of Nifedipine controlled-release tablets co-administered on day 6 ,a a single 3 mg oral dose of warfarin tablets co-administered on day 9.
Receives: Drug: Apatinib; Drug: Nifedipine GTIS; Drug: Warfarin Potassium

What is being measured

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

  1. Area under the plasma concentration versus time curve (AUC) of warfarin or nifedipine

    AUC0~t of warfarin and nifedipine in the absence or in presence of apatinib will be defined

    Measured: 1 year

Secondary outcomes (1)
  1. Number of participants with treatment-related adverse events as assessed by CTCAE v4.0

    to assess safety and tolerability of apatinib combined with warfarin or nifedipine in patients with advanced solid tumors. The vital signs, ECG, laboratory values and adverse events (AE and SAE) were judged according to NCI-CTCAE V4.0 criteria

    Measured: Day 1 to 21 ( Phase A)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Apatinib, Nifedipine GTIS and Warfarin Potassium in people with Cytochrome P450 Interaction, run by Jiangsu HengRui Medicine Co., Ltd. at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 7 Feb 2018. 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 China. 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 this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Area under the plasma concentration versus time curve (AUC) of warfarin or nifedipine (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Feb 2018.
