A Study of LY3039478 in Participants With Advanced Cancer

December 5, 2025 updated by: Eli Lilly and Company

A Phase 1 Study of LY3039478 in Patients With Advanced or Metastatic Cancer

The purpose of this study is to find a recommended dose level of LY3039478 that can safely be taken by participants with advanced cancer or cancer that has spread to other parts of the body, including but not limited to lymphoma. The study will also explore changes to various markers in blood cells and tissue. Finally, the study will help to document any tumor activity this drug may have.

Detailed Description

In Part A of this study, participants with advanced/metastatic cancer (including lymphoma) will receive increasing doses of LY3039478 to define the dose level for Part B, C, D and E. In Part B, C, D and E LY3039478 will be explored at a predefined fixed dose level. Participants in Part B and D must have a defined alteration in a certain molecular pathway. Enrollment of participants in Part B, C, D and E will start once Part A is completed. In Part F participants will receive increasing doses of LY3039478 in combination with prednisone to define the maximum tolerated dose level.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Part A and F: Number of Participants With Dose Limiting Toxicities (DLTs)
Time Frame: Baseline through the end of Cycle 1, Up to 28 Days
DLT was defined as an adverse event (AE) during Cycle 1 (Up to 28 Days) that was related to LY3039478 and fulfilled any 1 of the following criterion using the National Cancer Institute Common Terminology Criteria for Adverse Events, version 4.0 (NCI-CTCAE v 4.0): CTCAE Grade 3 non-hematological toxicity with a few exceptions, CTCAE Grade 4 hematological toxicity of greater than 5 days duration, any febrile neutropenia,Grade 3 thrombocytopenia with bleeding or Grade 4 thrombocytopenia, Any other significant toxicity deemed by the primary investigator and Lilly clinical research personnel to be dose limiting (for example, any toxicity that is possibly related to the study medication that requires the withdrawal of the participant from the study during Cycle 1).
Baseline through the end of Cycle 1, Up to 28 Days
Part A: Recommended Phase 2 Dose of LY3039478 : Maximum Tolerated Dose (MTD)
Time Frame: Baseline though the end of cycle 1 (28 days cycle)
MTD is defined as the highest tested dose that has less than 33% probability of causing a DLT during Cycle 1.
Baseline though the end of cycle 1 (28 days cycle)
Part B, C, D and E: Recommended Phase 2 Dose of LY3039478 : Maximum Tolerated Dose (MTD)
Time Frame: Baseline through the end of cycle 1 (28 days Cycle)
MTD is defined as the highest tested dose that has less than 33% probability of causing a DLT during Cycle 1.
Baseline through the end of cycle 1 (28 days Cycle)
Part F1 and F2: Recommended Phase 2 Dose of LY3039478
Time Frame: Baseline Up to 2 Months
Parts F1 and F2 compared loading dose three time per week with prednisone versus two times per week with prednisone. Even though the trial may have found an MTD, it did not identify an Recommended Phase 2 dose (RP2D).
Baseline Up to 2 Months
Part B, C, D, E and F: Percentage of Participants With Complete Response (CR) or Partial Response (PR) (Objective Response Rate [ORR])
Time Frame: Baseline to Disease Progression or Participant Discontinuation (Up To 20 Months)

Objective response is complete response (CR) + partial response (PR), as classified by the investigators according to the Response Evaluation Criteria In Solid Tumors (RECIST 1.1 ) guidelines. CR is disappearance of all target and non-target lesions; PR is greater than or equal to (>=) 30% decrease in sum of longest diameter of target lesions. Objective response rate is calculated as a total number of participants with CR or PR divided by the total number of participants treated multiplied by 100.

Analysis Population Description: Part D: 50 mg LY3039478 (Cohort 5) was assessed using Cheson criteria. Zero participants were analyzed for Part D: 50 mg LY3039478 (Cohort 4) because data were not collected. Data was not reported because both enrolled participants discontinued treatment early-one on Day 1 due to investigator decision and the other on Day 26 due to myocardial infarction, with no efficacy assessments performed.

Baseline to Disease Progression or Participant Discontinuation (Up To 20 Months)

Objective response is complete response (CR) + partial response (PR), as classified by the investigators according to the Response Evaluation Criteria In Solid Tumors (RECIST 1.1 ) guidelines.

The time from the date of first evidence of a confirmed complete to the date of objective progression or the date of death from any cause (whichever is earlier) as classified by RECIST 1.1 guidelines. For each participant who is not known to have died or to have had a progression of disease as of the data-inclusion cut-off date, duration of response will be censored at the date of last objective response assessment prior to the date of any subsequent systemic anticancer therapy. Progressive Disease (PD) is an increase of at least 20% in the sum of the diameters of target lesions, taking as reference the smallest sum on study (included baseline sum if that was the smallest on study). In addition, the sum must have demonstrated an absolute increase of at least 5 mm (the appearance of 1 or more new lesions was considered progression).

Part B, C, D, E and F: Progression Free Survival (PFS)
Time Frame: Baseline to Objective Progression or Death from Any Cause (Up To 17 Months)

Progression-free survival(PFS) time is defined as the time from the date of study enrollment to the first date of PD(symptomatic or objective) or death due to any cause,whichever occurs first.For participants who are not known to have died or progressed as of the data-inclusion cut-off date,PFS time will be censored at the date of the last objective progression-free disease assessment prior to the date of any subsequent systemic anticancer therapy. Progressive Disease(PD) is an increase of at least 20% in the sum of the diameters of target lesions,taking as reference the smallest sum on study(included baseline sum if that was the smallest on study).In addition, the sum must have demonstrated an absolute increase of at least 5 mm(the appearance of 1 or more new lesions was considered progression).

Part B, C, D, E and F: Overall Survival (OS)
Time Frame: Baseline to Date of Death from Any Cause (Up To 49 Months)
Overall Survival (OS) was defined as the time from the date of study enrollment to the date of death from any cause. For participants not known to have died as of the data cut-off date, OS time was censored at the last contact date the participants was known to be alive prior to the cut-off date.
