Trial summary

The purpose of this study is to assess the effect LY2603618 on a protein [enzyme cytochrome P (CYP) 2D6] which is involved in the metabolic pathway of Desipramine in participants with cancer. This is a drug interaction study so the treatment of the disease will not be the main purpose of the study. Read more about this study

About this study

Official title: A Study in Cancer Patients to Evaluate the Ability of LY2603618 to Act as an Inhibitor of CYP2D6 Using Desipramine as a Probe Substrate

The purpose of this study is to assess the effect LY2603618 on a protein [enzyme cytochrome P (CYP) 2D6] which is involved in the metabolic pathway of Desipramine in participants with cancer. This is a drug interaction study so the treatment of the disease will not be the main purpose of the study.

The study involves two single doses of 50 milligrams (mg), 1 tablet by mouth, on Day 1 of Period 1 and 2. In Period 1 Desipramine will be administered alone. In Period 2 Desipramine will be administered in combination with LY2603618. LY2603618 will be administered as a 275mg intravenous (IV) infusion over 1 hour (hr).

Desipramine will be administered at the end of the LY2603618 infusion. Information about any side effects that may occur will also be collected.

Secondary outcomes (1)
  1. Number of Participants With a Tumor Response

    Tumor response is complete response (CR) + partial response (PR), as classified by the investigators according to the Response Evaluation Criteria In Solid Tumors (RECIST) criteria (Version 1.1). CR is the disappearance of all target and non-target lesions and PR is a ≥30% decrease in sum of longest diameter of target lesions. Number of participants with a tumor response is the total number of participants with CR or PR.

    Measured: Baseline to study completion up to 11 cycles of 21-day cycles

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing LY2603618, Desipramine and Pemetrexed in people with Cancer, run by Eli Lilly and Company at 1 site in United States.

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 12 inclusion and 13 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: finished, as of the sponsor's last update on 25 Oct 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 United States. 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?

Yes. Results are posted in the registry (first posted 25 Oct 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Plasma Pharmacokinetics of LY2603618: the Maximum Concentration of LY2603618 in the Plasma (Cmax) (time frame: Period 2 only: Predose, 1, 2, 4, 6, 8, 12, 24, 48, 72, 96, 120 and 144 hours post dose). The study lists 6 primary outcomes in all. 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 25 Oct 2018.
