Study Endpoints

Primary Endpoints

Progression Free Survival (PFS) at the Time of Primary Results
From date of randomization until date of progression or date of death from any cause, whichever comes first, assessed up to approximately 39 months

Progression-free survival (PFS) is the time from randomization to the earliest date of RECIST 1.0 assessment of disease progression (with radiological evidence), death from any cause, or censoring. Disease progression was assessed by the Investigator and defined by RECIST v1.0 as a 20% increase in the sum of the longest diameter of target lesions, a measurable increase in a non-target lesion, or the appearance of new lesions.

Secondary Endpoints

Progression Free Survival (PFS) at the Time of Final Analysis
From date of randomization until date of progression or date of death from any cause, whichever comes first, assessed up to approximately 45 months
Overall Survival (OS) (IIT Population)
From date of randomization until date of death from any cause, assessed up approximately 165 months
Overall Survival (OS) (Central HER2+ Population)
From date of randomization until date of death from any cause, assessed up approximately 165 months

Frequently asked questions about lapatinib ditosylate

What is lapatinib ditosylate used for?

Lapatinib ditosylate is an investigational small molecule studied for breast cancer. It has been evaluated in HER2/Neu-positive metastatic breast cancer, where it was compared with trastuzumab alongside chemotherapy. The clinical program focuses on biomarker-selected patients whose tumors express the relevant receptor target.

What does lapatinib ditosylate target?

Lapatinib ditosylate targets EGFR and ERBB2, also known as HER2. It is an inhibitor of these receptor tyrosine kinases, which are involved in signaling that drives tumor cell growth in breast cancer. Targeting both receptors is intended to block that signaling in ERBB2-positive disease.

Who makes lapatinib ditosylate?

Lapatinib ditosylate is developed by Novartis AG, which trades under the ticker NVS. Novartis is the sponsor associated with the clinical development program for this small molecule in breast cancer.

What phase is lapatinib ditosylate in?

Lapatinib ditosylate is in Phase 3 clinical development. It is investigational and has not been established as approved for breast cancer. The Phase 3 trial in HER2/Neu-positive metastatic breast cancer has completed, and no active trials are currently listed for this asset.

What clinical trials is lapatinib ditosylate in?

Lapatinib ditosylate has been studied in the completed Phase 3 trial NCT00667251, titled Chemotherapy and Lapatinib or Trastuzumab in Treating Women With HER2/Neu-Positive Metastatic Breast Cancer. The trial enrolled 652 women aged 18 and older across the United States, Europe, Asia, and other regions, with an active-controlled design.
