Korábbi kezelés

• Low trauma fracture(s) occurring within 12 months prior to subject's first visit (defined as a fracture that results from a fall from a standing height or less, excluding fingers, toes, face and skull)
• Already receiving and/or previously received GnRH analogs within 1 year before breast cancer diagnosis
• Use of medications that may impact subject safety and/or affect the PK of the drug and hormonal assessments including but not limited to:

• Exposure to any investigational agent within 30 days prior to the first dose of TOL2506
  • See contact information to obtain inclusion/exclusion criteria for males

Más betegség

• History of treatment for osteopenia/osteoporosis or baseline bone mineral density Z-score ≤ -2.0
• Conditions that preclude bone mineral density measurement (lumbar spine/bilateral hip surgery with hardware in place, abdominal clips, umbilical ring [not willing to remove] or weight that exceeds the DEXA machine limitation)
• Psychiatric, addictive, or other disorders that would preclude study compliance
• Known hypersensitivity, idiosyncratic, or allergic reactions to GnRH, GnRH agonist/analogs or to any of the components of the IP

Laborértékek

  • Alanine aminotransferase (ALT) ≥ 2X upper limit of normal (ULN)
  • Aspartate aminotransferase (AST) ≥ 2X ULN
  • Bilirubin ≥ 2X ULN
  • Alkaline phosphatase ≥ 2X ULN

• History of significantly abnormal ECG or screening 12-lead ECG demonstrating any of the following:
  • HR > 100 BPM
  • QRS > 120 msec
  • QTc > 450 msec
  • PR > 220 msec
• Prior (within 28 days prior to Day 1) and/or concomitant use of medications known to prolong the QT/QTc interval
• Any other medical condition or serious illness, presence of a second malignancy under current treatment or follow-up, or the presence of clinically significant findings on the physical exam, laboratory testing, medical history (including conditions that may be associated with low bone mass), that in the opinion of the Investigator may interfere with trial conduct, subject safety, or interpretation of study results

• Breastfeeding
• Life expectancy < 12 months
• Eastern Cooperative Oncology Group (ECOG) performance status ≥ 3
• Sexually active with a male partner and not willing to use non-hormonal contraceptive methods throughout the study

• Female
• Able to understand the investigational nature of this study and provide written informed consent prior to the participation in the trial
• Age 18 to 49, inclusive
• Diagnosis of Stage I, II, or III HR+, HER2-negative breast cancer (ER>1% and/or, PR>1%, HER2-negative per ASCO CAP guidelines)
• Is a candidate for endocrine therapy + ovarian suppression LH > 4 IU/L within 28 days prior to Day 1
• Is premenopausal as defined by:
  • E2 > 30 pg/mL
