This is a multicenter, open label, nonrandomized, sequential dose escalation/dose ranging, multiple dose study designed to evaluate the safety, toxicity, and PK as well as preliminary efficacy of BTX-A51 alone and in combination with fulvestrant in subjects with advanced solid tumors. The study will be done in three phases, described below.
Phase 1a (Dose Escalation Phase):
The Phase 1a portion is designed to determine the dose limiting toxicities (DLTs), maximum tolerated dose (MTD), and recommended Phase 2 dose (RP2D) of orally administered BTX-A51. BTX-A51 will be administered once daily on a weekly schedule of 5 days on/2 days off. Dose escalation will proceed according to a modified 3+3 design. Each cycle will consist of 28 days (4 weeks), and the DLT observation period will be the first cycle (i.e., 28 days after initiation of dosing). A DLT may be observed in no more than 0 out of 3 or 1 out of 6 subjects who have completed the DLT observation period before the next cohort initiates accrual. Barring DLT, sequential dose escalation of BTX-A51 is planned with up to a total of 6 dose levels; on the basis of these an MTD will be identified. The MTD is defined as the highest dose level with a subject incidence of DLTs of 0 or 1 out of 6 during the first 28 days of study drug dosing. A minimum of 6 subjects needs to be treated at a dose level before this dose level can be deemed as the MTD.
Phase 1b (Monotherapy Dose Ranging Phase):
Dose expansion may begin when the RP2D has been determined. Up to 40 additional subjects at each of the 2 dose levels will be enrolled to evaluate safety and preliminary efficacy of BTX-A51 in subjects with estrogen receptor positive (ER+), human epidermal growth factor receptor 2 negative (HER2-), GATA3 mutant (mt) and wild-type (wt) metastatic breast cancer (mBC). Dosing in this phase of the study consists of the first cycle of therapy (i.e., 28 days).
Phase 1c (Combination Safety Phase):
The Phase 1c portion will evaluate the safety and tolerability of orally administered BTX-A51 at two dose levels combined with fulvestrant. The first combo cohort may be initiated after DEC review of the 6 subject lead-in phase of the high dose monotherapy cohort in Phase 1b. Dose escalation will proceed according to a 3+3 design. Each cycle will consist of 28 days (4 weeks), and the DLT observation period will be the first cycle (i.e., 28 days after initiation of dosing).

This study is a multicenter, international, open-label phase II study. Based on inclusion/exclusion criteria, eligible pre and postmenopausal patients with newly diagnosed metastatic luminal hormone receptor-positive and HER2 negative breast cancer, will be prospectively treated with a standard combination of hormone therapy (Letrozole or Anastrozole) and Palbociclib. This combination will continue until progression. Treatment response will be evaluated every three months using clinical and radiological assessments (Revised RECIST guidelines).
Patients will undergo serial liquid biopsies (blood tests) for plasma molecular fingerprinting by the Quantum Optics technology. This study will be the first program exploring the adjunction of the Quantum Optics technology on liquid biopsies to define individual 'molecular fingerprinting profiles' to predict the individual therapeutic effects of Palbociclib combined with Aromatase Inhibitors (AI) (plus ovarian function suppression (OFS) for pre/peri-menopausal patients) in luminal hormone receptor-positive and HER2 negative advanced breast cancer. Batteries of algorithmic tests will integrate the variables obtained by Quantum Optics (to evaluate the efficacy or not of the combination of Palbociclib + Aromatase Inhibitors (AI) ). This approach introduces the concept of singularity to break from the classic idea of "one size fits all".
Eligibility: 18 Years to · Female · To be enrolled in the study, patients should meet the following inclusion criteria:
1. Written informed consent before beginning specific protocol procedures including expected cooperation of the patients for the treatment and follow-up must be obtained and documented according to the local regulatory requirements.
