Brief summary

The primary objective of this study is to determine the maximum tolerated dose (MTD) regimen for the combination therapy of LY573636 and pemetrexed that may be safely administered to patients with a solid tumor that is not amenable to curative therapy.

Interventions

Individualized dose is dependent on a patient's height, weight, and gender and is adjusted to target a specific exposure range corrected for a patient's laboratory parameters. Intravenous dosing is completed once per cycle (cycle equals either 21 or 28 days). Patients may continue on study drug until disease progression, unacceptable toxicity, or other withdrawal criteria are met. Patients are pretreated with folic acid \[350 micrograms (µg) to 1000 µg orally, daily\], Vitamin B12 (1000 µg intramuscular injection every 9 weeks), and dexamethasone \[4 milligrams (mg) orally, twice daily or equivalent\].

DRUGPemetrexed

375 to 500 milligrams per square meter (mg/m\^2), intravenous dosing is completed once per cycle (cycle equals either 21 or 28 days). Patients may continue on study drug until disease progression, unacceptable toxicity, or other withdrawal criteria are met. Patients are pretreated with folic acid (350 µg to 1000 µg orally, daily), Vitamin B12 (1000 µg intramuscular injection every 9 weeks), and dexamethasone (4 mg orally, twice daily or equivalent).

Design outcomes

Primary

MeasureTime frameDescription
Recommended Phase 2 DoseBaseline to toxicity [up to end of Cycle 1 (cycle = 21 or 28 days)]Based on maximum tolerated dose (MTD) in Cycle 1: highest dose where \<33% participants (pts) had dose-limiting toxicity (DLT). DLTs were adverse events (AE) possibly related to study drug or AEs that met any of National Cancer Institute's (NCI) Common Terminology Criteria for AEs (CTAE): Grade (G) 4 neutropenia lasting ≥5 days; G4 neutropenia with fever, G4 thrombocytopenia, G3 thrombocytopenia with bleeding, ≥G3 non-hematologic toxicity (except nausea/vomiting and diarrhea controlled by medication; electrolyte toxicity resolved with standard replacement treatment; alopecia; and elevated alanine aminotransferase or aspartate aminotransferase with preexisting hepatic metastasis, if agreed by investigator). Investigators, with sponsor, could declare a DLT if pt experienced increasing toxicity during treatment and it was clear that further treatment would expose pt to excessive risk. Enrollment was stopped during the dose-escalation phase, thus further dose-escalation was not explored.

Secondary

MeasureTime frameDescription
Number of Participants With Clinically Significant EffectsBaseline to end of study (up to 1 year of treatment plus 30-day follow-up)Clinically significant effects were defined as serious and other non-serious adverse events (AEs) regardless of causality. A summary of serious and all other non-serious AEs is located in the Reported Adverse Events module.
Percentage of Participants With a Tumor ResponseBaseline to progressive disease (up to 1 year of treatment plus 30-day follow-up)Tumor response was evaluated using Response Evaluation Criteria In Solid Tumors (RECIST) criteria and confirmed by repeat assessment. Complete Response (CR) was defined as the disappearance of all target lesions and the normalization of tumor marker levels for non-target lesions; Partial Response (PR) was defined as at least a 30% decrease in the sum of the longest diameter of target lesions. Percentage of participants with a tumor response = (number of participants with CR or PR/number of enrolled participants)\*100.

AUCalb is a surrogate measure of exposure to unbound (free) LY573636.

Outcome results

Primary

Recommended Phase 2 Dose

Based on maximum tolerated dose (MTD) in Cycle 1: highest dose where \<33% participants (pts) had dose-limiting toxicity (DLT). DLTs were adverse events (AE) possibly related to study drug or AEs that met any of National Cancer Institute's (NCI) Common Terminology Criteria for AEs (CTAE): Grade (G) 4 neutropenia lasting ≥5 days; G4 neutropenia with fever, G4 thrombocytopenia, G3 thrombocytopenia with bleeding, ≥G3 non-hematologic toxicity (except nausea/vomiting and diarrhea controlled by medication; electrolyte toxicity resolved with standard replacement treatment; alopecia; and elevated alanine aminotransferase or aspartate aminotransferase with preexisting hepatic metastasis, if agreed by investigator). Investigators, with sponsor, could declare a DLT if pt experienced increasing toxicity during treatment and it was clear that further treatment would expose pt to excessive risk. Enrollment was stopped during the dose-escalation phase, thus further dose-escalation was not explored.

Time frame: Baseline to toxicity [up to end of Cycle 1 (cycle = 21 or 28 days)]

Population: Enrollment was stopped during the dose-escalation phase and it was too early to assess the recommended dose for Phase 2 or to estimate the MTD, therefore zero participants were analyzed.

Secondary

Number of Participants With Clinically Significant Effects

Clinically significant effects were defined as serious and other non-serious adverse events (AEs) regardless of causality. A summary of serious and all other non-serious AEs is located in the Reported Adverse Events module.

Time frame: Baseline to end of study (up to 1 year of treatment plus 30-day follow-up)

Population: All enrolled participants: those who received 1 or more doses of LY573636 or pemetrexed.
