Dose Escalation of Lapatinib With Paclitaxel in Ovarian Cancer

June 17, 2025 updated by: Frederick R. Ueland, M.D.

A Phase I Dose-Escalation Study on the Safety of Lapatinib With Dose-Dense Paclitaxel in Patients With Platinum-Resistant Ovarian Cancer

This trial will be a phase I dose-escalation study of lapatinib and paclitaxel for platinum-resistant ovarian cancer, which will establish the phase II dose for subsequent efficacy trials.

Detailed Description

While ABCB1 (P-glycoprotein 1) upregulation after paclitaxel administration is well known, there is currently no clinically available method for preventing or overcoming it. To develop a therapy able to prevent ABCB1 upregulation and paclitaxel resistance, several ABCB1 inhibitors have been evaluated in combination with paclitaxel in preclinical model systems. Pulsed-dose lapatinib and paclitaxel are synergistic and inhibition of ABCB1 by lapatinib increases sensitivity to paclitaxel. Lapatinib is FDA approved, orally available, and previously studied in combination with weekly paclitaxel for breast cancer at doses of 1000mg to 1250mg daily (7000-8250mg per week). This trial will use twice-daily dosing of lapatinib at a starting dose of 750 mg for 2 days (1500mg a day and 3000mg weekly dose), which is less than half of the continuous dose and has been shown to achieve plasma concentrations at 48 hours that are associated with synergy. Therefore, these findings can be translated into a novel, well-tolerated, and convenient combination regimen with significant potential for clinical activity. This trial will be a phase I dose-escalation study of lapatinib and paclitaxel for platinum-resistant ovarian cancer, which will establish the phase II dose for subsequent efficacy trials.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
