A Phase Ib Trial of LY2157299 (TGFβR1 Kinase Inhibitor) With Paclitaxel in Patients With Triple Negative Metastatic Breast Cancer

This phase I trial studies the side effects and best dose of Galunisertib when given together
with paclitaxel in treating patients with androgen receptor negative or triple negative
breast cancer that has spread to other places in the body. Some tumors need growth factors,
which are made by the body's white blood cells, to keep growing. Galunisertib may interfere
with growth factors and help cause tumor cells to die. Drugs used in chemotherapy, such as
paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the
cells, by stopping them from dividing, or by stopping them from spreading. Giving
Galunisertib together with paclitaxel may kill more tumor cells.

PRIMARY OBJECTIVES:

I. To assess the safety and tolerability of paclitaxel when administered with LY2157299
(Galunisertib).

II. To determine the maximally tolerated dose (MTD) of paclitaxel + LY2157299. III. To
determine the recommended dose of paclitaxel with LY2157299 for phase II studies.

SECONDARY OBJECTIVES:

I. To evaluate the efficacy, as measured by median progression free survival (PFS), of
paclitaxel + LY2157299 in patients with metastatic androgen receptor negative triple negative
metastatic breast cancer.

II. To evaluate the efficacy, as measured by clinical benefit rate (CBR), of paclitaxel +
LY2157299 in patients with androgen receptor negative metastatic triple negative metastatic
breast cancer.

III. To determine the overall response rate (ORR) of paclitaxel + LY2157299 in patients with
androgen receptor negative metastatic triple negative breast cancer.

TERTIARY OBJECTIVES:

I. To interrogate the entire coding sequence of 236 cancer-related genes (3,769 exons) plus
47 introns from 19 genes often rearranged or altered in cancer.

II. Nanostring analysis of established gene expression signatures. III. Determine breast
cancer subtype by PAM50 testing and correlate with response.

IV. To measure changes in circulating plasma transforming growth factor beta 1 (TGFB1),
interleukin (IL)-6, and cluster of differentiation 34 (CD34) positive (+), peripheral blood
mononuclear cells (PBMCs) induced by LY2157299.

OUTLINE: This is a dose-escalation study of Galunisertib.

Patients receive paclitaxel intravenously (IV) on days 1, 8, and 15. Patients also receive
Galunisertib orally (PO) twice daily (BID) on days 1-14. Courses repeat every 28 days in the
absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up periodically.

[FFPB] or fresh frozen tissue from original diagnosis or metastatic setting) for
correlative studies; patients will not be able to start study drugs without tumor
tissue availability; patients without available tumor tissue can still participate if
willing to have a fresh biopsy of a metastatic lesion that is deemed to be medically
safe (except for bone metastases)

- Any number of prior therapies as long as patients have adequate performance status and
meet all other eligibility criteria.

- Patients must be able to swallow and retain oral medication

- Pre-menopausal patients must have a negative pregnancy test and agree to use birth
control methods while participating in the study; women of childbearing age and their
male counterparts should use a barrier method of contraception during and for 3 months
following protocol therapy

- Patients must complete all screening assessments as outlined in the protocol
