Study Endpoints

Primary Endpoints

Percentage of Participants With Hematological Improvement (HI)
Baseline through end of study treatment (24 weeks)

Percentage of participants with hematological improvement (HI) based on International Working Group (IWG) 2006 criteria in participants with very low, low, and intermediate-risk myelodysplastic syndromes treated with Galunisertib plus best supportive care, as assessed by the International Prognostic Scoring System (IPSS-R). To be classified as an HI responder, the HI response must have lasted at least 8 weeks (56 days).

Percentage of Participants Who Are Transfusion-free or Have Hemoglobin (Hb) Increase ≥1.5 Grams/Deciliter Maintained for 8 Weeks During Phase 3
Baseline through end of study treatment (24 weeks)

Comparison of the percentage of participants with very low-, low-,and intermediate-risk MDS who were transfusion-free or had an increase ≥1.5 g/dL in hemoglobin (Hb) maintained for at least 8 weeks within the first 24 weeks of treatment with galunisertib plus best supportive care or placebo plus best supportive care and assessed by IPSS-R. The Phase 3 portion of this study was not conducted because efficacy level required in phase 2 to move forward to phase 3 was not achieved.

Overall Survival (OS)
Randomization to Date of Death from Any Cause (Up To 20.5 Months)

OS is defined as the time from the date of randomization until death from any cause. For participants not known to have died by the data-inclusion cutoff date, OS is censored at the last date they were known to be alive.

Proportion of Patients With Completion of 4 Cycles of CT + GB
2 years

Completion of 4 cycles of CT + GB- completion of a cycle will be defined as receiving both carboplatin/paclitaxel and taking ≥75% of the doses of GB for the cycle.

Number of Participants with Galunisertib in Combination with Durvalumab Dose-Limiting Toxicities (DLTs)
Cycle 1 (28 Days)
Estimated Change from Baseline in Fridericia-corrected QT Interval (QTcF) by Specific Galunisertib Concentrations
Baseline through 72 hours after administration of study drug
Change from Baseline in Immune Cell Subsets
Baseline up to Cycle 6 (Cycle = 28 Days)
Change from Baseline in Serum Cytokines
Baseline up to Cycle 6 (Cycle = 28 Days)
Change from Baseline in Humoral Immunity
Baseline up to Cycle 6 (Cycle = 28 Days)
Phase 1b: Maximum Tolerated Dose (MTD) of Galunisertib in Combination With Nivolumab
Cycle 1 through Cycle 2 (Up to 2 Months)

The MTD is defined as the highest tested dose that has less than 33% probability of causing a dose limiting toxicity (DLT).

Phase 1b: Recommended Phase 2 Dose
Time of first phase 1b dose until time of last phase 1b dose (up to 1 year)

The recommended Phase 2 dose was the highest dose where less than 1/3 of participants experienced dose limiting toxicities (DLTs). The recommended dose was determined based on a review of overall toxicity, dose reductions, omissions, and pharmacokinetic information from Phase 1b.

Phase 2: Overall Survival (OS)
Baseline to date of death from any cause (up to 2 years)

Overall survival is defined as the time from the date of randomization to the date of death from any cause. For each participant who is not known to have died as of the data-inclusion cut-off date for a particular analysis, overall survival duration was censored for that analysis at the date of last prior contact.

Frequently asked questions about Galunisertib

What is Galunisertib used for?

Galunisertib is an investigational small molecule being studied for use in oncology, including myelodysplastic syndromes, neoplasms, glioblastoma, carcinosarcoma, ovarian cancer, and solid tumors. It is developed by Eli Lilly and Company and is currently in clinical trials, though it is not yet approved by the FDA.

How does Galunisertib work?

Galunisertib is a small molecule that targets the TGF-beta receptor, inhibiting its activity. By blocking this pathway, it aims to disrupt tumor growth and progression. This mechanism is being explored in various cancer types, including glioblastoma and solid tumors, as part of Eli Lilly's oncology pipeline.

Who makes Galunisertib?

Galunisertib is developed by Eli Lilly and Company, a pharmaceutical company traded on the NYSE under the ticker LLY. The drug is currently in clinical development for multiple oncology indications, including glioblastoma and solid tumors, though it has not yet received regulatory approval.

What phase is Galunisertib in?

Galunisertib is in Phase 1 clinical development, with one completed Phase 1 trial. It has also been studied in a Phase 2 trial for recurrent glioblastoma, which is completed. The drug remains investigational and is not yet approved by the FDA for any indication.

What clinical trials is Galunisertib in?

Galunisertib has been studied in several completed trials, including NCT01373164 for metastatic cancer and pancreatic cancer, NCT01582269 for recurrent glioblastoma, NCT02752919 in healthy participants, and NCT03206177 for carcinosarcoma of the uterus or ovary. These trials have collectively enrolled over 390 participants.

Is Galunisertib the same as LY2157299?

Galunisertib is also known as LY2157299, an alternative name used in clinical research. It is a small molecule TGF-beta receptor inhibitor developed by Eli Lilly and Company. The drug is being investigated for various cancers, including glioblastoma and solid tumors, but is not yet approved.
