Brief Summary:
This is a multicenter, randomized, 2 arm, open label, phase II study. It is designed to compare the efficacy and safety of abemaciclib combined with ET (letrozole or fulvestrant) versus a short course with induction chemotherapy with paclitaxel followed by maintenance therapy with abemaciclib combined with ET (letrozole or fulvestrant) in patients with previously untreated, unresectable locally advanced, or metastatic HR positive/HER2 negative breast cancer with aggressive disease criteria.
| Condition or disease | Intervention/treatment | Phase |

| Breast Cancer Metastatic | Drug: Abemaciclib Drug: Paclitaxel Drug: Letrozole Drug: Fulvestrant | Phase 2 |
The ABIGAIL study aims to provide consistent evidence that the combination of abemaciclib with ET -consisting of letrozole or fulvestrant-as first-line regimen is non-inferior to the optimal first-line chemotherapy -consisting of weekly paclitaxel-in terms of early ORR after the first 12 weeks of treatment in patients with HR-positive/HER2-negative ABC and at least one feature of aggressive disease associated with poor prognosis.

Patients with past HBV infection or resolved HBV infection (defined as having a negative hepatitis B surface antibody [HBsAg] test and a positive hepatitis B core antibody [HBcAb] test, accompanied by a negative HBV DNA test) are eligible. Patients positive for HCV antibody are eligible only if polymerase chain reaction (PCR) is negative for HCV RNA.
- Active bacterial or fungal infection at the time of enrolment (requiring antibiotics or antifungal agents at time of initiating study treatment).
- History of any of the following conditions: syncope of cardiovascular etiology, ventricular arrhythmia of pathological origin (including, but not limited to, ventricular tachycardia and ventricular fibrillation), or sudden cardiac arrest.
