No results posted yet for this study

Summary

The aim of this Phase 1b/2 study is to investigate the safety, efficacy, and pharmacokinetics (PK) of a single dose of LS301-IT, a novel fluorescence imaging agent developed by Integro Theranostics (IT), administered by intravenous (IV) injection in female patients undergoing partial mastectomy for DCIS (whether or not undergoing planned SLNB) or Stage I-II primary invasive breast cancer undergoing SLNB. Safety is the primary objective of this study, followed by efficacy that will be assessed from fluorescence imaging observations and data.

DRUG

LS301-IT 0.025 mg/kg

The dose of LS301-IT planned to be administered to the first cohort of patients is 0.025 mg/kg. Depending on the results the dose for subsequent cohorts will be increased to 0.05, 0.075, and 0.1 mg/kg; the dose may also be decreased (by 50% as necessary). The optimal dose determined in Periods 1 and 2 will be administered to patients in Period 3.

DRUG

LS301-IT 0.05 mg/kg

Depending on the results the dose for subsequent cohorts will be increased to 0.05, 0.075, and 0.1 mg/kg; the dose may also be decreased. The optimal dose determined in Periods 1 and 2 will be administered to patients in Period 3.
