E.1.1 | Medical condition(s) being investigated |
Triple negative breast cancer
|
|
E.1.1.2 | Therapeutic area | Diseases [C] - Cancer [C04] |
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess whether adding LCL161 to weekly paclitaxel enhances the efficacy of paclitaxel in women with triple negative breast cancer,
analyzed separately in the gene expression signature negative and
positive groups. |
|
E.2.2 | Secondary objectives of the trial |
1. To characterize the safety and tolerability of the LCL161/paclitaxel
combination compared to weekly paclitaxel alone.
2. To evaluate whether combination treatment with LCL161 and
paclitaxel is associated with increased apoptosis compared to weekly
paclitaxel alone.
3. To evaluate the PK of LCL161 when given in combination with
Paclitaxel
4. To assess other indicators of disease response for the LCL161 +
Paclitaxel combination compared to paclitaxel alone.
5. To assess whether adding LCL161 to weekly paclitaxel enhances the
efficacy of paclitaxel in women with triple negative breast cancer
regardless of tumor gene expression signature status
6. To assess whether use of the gene expression signature identifies
tumors more likely to respond to treatment with LCL161 and paclitaxel
7. To assess whether the gene expression signature is correlated with
response to single agent paclitaxel
