Dose-Escalation Study of LY573636-sodium and Liposomal Doxorubicin in Patients With Advanced Solid Tumors

A Phase 1b, Multicenter, Dose-Escalation Study of LY573636-sodium in Combination With Liposomal Doxorubicin in Patients With Advanced Solid Tumors

The goal of this study is to determine the dose of LY573636-sodium (hereafter referred to as LY573636) that can be administered safely in combination with liposomal doxorubicin in patients with advanced cancer who have failed a prior treatment.

The study consists of a dose escalation phase to the maximum tolerated dose (MTD) and a dose confirmation phase in patients with platinum resistant epithelial ovarian, fallopian tube or primary peritoneal cancer who have never been treated with doxorubicin.

Arms and Interventions

Participant Group / Arm

Intervention / Treatment

Experimental: LY573636 + Liposomal Doxorubicin

Drug: LY573636-sodium; Individualized dose is dependent on participant's height, weight, gender and is adjusted to target a specific exposure range corrected for a participant's laboratory parameters. Intravenous dosing is done on Day 1 of a 28-day cycle. Participants may continue on study drug until disease progression, unacceptable toxicity, cumulative dose of 550 milligrams per square meter (mg/m²) of liposomal doxorubicin or doxorubicin is reached, or other withdrawal criterion is met.; Other Names: Tasisulam-sodium; Drug: Liposomal Doxorubicin; 40 mg/m² on Day 1, given intravenously of each 28-day cycle Participants may continue on study drug until disease progression, unacceptable toxicity, cumulative dose of 550 mg/m² of liposomal doxorubicin or doxorubicin is reached, or other withdrawal criterion are met.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Recommended Phase 2 Dose	Recommended Phase 2 dose was determined by maximum tolerated dose (MTD), which is corrected for the participant's predose albumin to identify the albumin-corrected exposure range of LY 573636 when combined with liposomal doxorubicin. MTD is the highest dose with <33% of participants having a dose-limiting toxicity (DLT) in the first 28-day cycle of treatment. DLT is an adverse event (AE) that is likely related to the study drug or combination and fulfills any 1 of the following: Common Terminology Criteria for AE (CTCAE, Version 3.0) Grade (Gr) 4 hematologic toxicity; Gr 3 nonhematologic toxicity (excluding controllable nausea/vomiting or diarrhea and alopecia); Gr 3 electrolyte toxicity that is not resolved with standard treatments. Those who enter the study with Gr 2 hepatic enzyme abnormalities, DLT for an isolated Gr 3 hepatic enzyme abnormality is determined by investigators; a DLT can be declared if a participant experiences increasing toxicity during treatment.	Predose up to 28 days postdose in Cycle 1

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Participants With Clinically Significant Events	Clinically significant events are defined as serious adverse events (SAEs), regardless of causality, during the study including the 30-day follow-up period. A summary of SAEs and other nonserious adverse events is located in the Reported Adverse Event section. Death due to progressive disease was not considered as an SAE.	Baseline to study completion up to 18.49 months
Pharmacokinetics: Maximum Concentration (Cmax) of LY573636		Predose, 30 minutes (min), 2 hours (h), 4 h, 166 h, 360 h and 698 h postdose in Cycle 1; Predose, 30 min, 2 h, 4 h, 166 h, 360 h and 698 h postdose in Cycle 2; Predose, 166h, 360h and 698 h postdose in Cycle 3
Number of Participants With Tumor Response	Number of participants with tumor response = number of participants with complete response (CR) + number of participants with partial response (PR), as classified by the investigators according to the Response Evaluation Criteria In Solid Tumors (RECIST) guidelines. CR is the disappearance of all target and non-target lesions; PR is a ≥30% decrease in the sum of longest diameter of target lesions.	Baseline to measured progressive disease up to 4.7 months
Pharmacokinetics: Area Under the Curve of LY573636 Above the Albumin Corrected Threshold (AUCalb)	LY573636 has been found to be highly bound to albumin. AUCalb is a surrogate measure of exposure to unbound (free) LY573636.	Predose, 30 min, 2 h, 4 h, 166 h, 360 h and 698 h postdose in Cycle 1; Predose, 30 min, 2 h, 4 h, 166 h, 360 h and 698 h postdose in Cycle 2; Predose, 166h, 360h and 698 h postdose in Cycle 3

Other Outcome Measures

Outcome Measure	Time Frame
Number of Participants Who Died Due to Progressive Disease During the 30 Days Following Discontinuation From Study Treatment	From date of randomization until up to 30 days post study treatment discontinuation, assessed up to 4.7 months
