Ovarian Suppression Evaluating Subcutaneous Leuprolide Acetate in Breast Cancer

Registration Number
NCT04906395
Lead Sponsor
Tolmar Inc.
Brief Summary

This is a phase 3, single arm, open-label study evaluating the effectiveness of TOL2506 to suppress ovarian function in premenopausal women with HR+, HER2-negative breast cancer. The study will also aim to assess the safety of TOL2506 in men with HR+, HER2-negative breast cancer. The Screening Period will be conducted in two parts: 1) an abbreviated, initial screening where premenopausal status will be determined prior to neoadjuvant or adjuvant chemotherapy (if planned) and 2) the full screening assessment conducted after neoadjuvant or adjuvant chemotherapy (or for subjects who enter the study without having received chemotherapy). Following the Screening Period, eligible subjects will enter into the 48 week Treatment Period in 1 of 2 groups: those who will receive tamoxifen concurrently with TOL2506 or those who will initiate therapy with an AI (letrozole, anastrozole, or exemestane) beginning 6 weeks after the first administration of TOL2506, upon confirmation that estradiol (E2) levels of \< 20 pg/mL (testosterone levels \< 50 ng/dL in males) have been achieved. After Week 12, subjects will be allowed to switch from receiving an AI to receiving tamoxifen or from tamoxifen to AI at the discretion of the Investigator. However, a switch is not permitted 28 days prior to a dosing visit (eg, Week 24, 36, and 48 where a pre-dose blood sample for PK and PD analysis will be drawn). At the end of the Treatment Period, upon completion of the End of Study Visit (Visit 9, Week 48) subjects may be eligible to participate in a Safety Extension Study under a separate Protocol.

Inclusion Criteria

Female

  1. Able to understand the investigational nature of this study and provide written informed consent prior to the participation in the trial

  2. Age 18 to 49, inclusive

  3. Diagnosis of Stage I, II, or III HR+, HER2-negative breast cancer (ER>1% and/or, PR>1%, HER2-negative per ASCO CAP guidelines)

  4. Is a candidate for endocrine therapy + ovarian suppression LH > 4 IU/L within 28 days prior to Day 1

  5. Is premenopausal as defined by:

    • E2 > 30 pg/mL
    • follicle stimulating hormone (FSH) < 40 IU/L
    • regular menses (eg, menstrual cycle length of 21 to 35 days) Note: premenopausal status must be determined before neo/adjuvant chemotherapy in patients for which it is planned or prior to Day 1 in patients who did not have prior chemotherapy. If premenopausal status was not determined prior to chemotherapy, E2 and FSH must meet the above criteria when measured 2 weeks or more after the end of the final cycle of chemotherapy.
Exclusion Criteria

  4. Eastern Cooperative Oncology Group (ECOG) performance status ≥ 3

  5. Unacceptable hepatic function as determined by any of the following:

    1. Alanine aminotransferase (ALT) ≥ 2X upper limit of normal (ULN)
    2. Aspartate aminotransferase (AST) ≥ 2X ULN
    3. Bilirubin ≥ 2X ULN

    1. Creatinine ≥ 3X ULN
    2. Creatinine clearance ≤ 30 mL/minute
    3. Creatinine clearance ≤ 60 mL/minute in subjects with bone density 1.5 standard deviations below the young adult normal mean
  7. History of significantly abnormal ECG or screening 12-lead ECG demonstrating any of the following:

    1. HR > 100 BPM
    2. QRS > 120 msec
    3. QTc > 450 msec
    4. PR > 220 msec
  8. Prior (within 28 days prior to Day 1) and/or concomitant use of medications known to prolong the QT/QTc interval

  9. Prior use of tamoxifen, other SERMs (eg, raloxifene) or antagonists (eg, fulvestrant), aromatase inhibitor, mammalian target of rapamycin (mTOR) inhibitors, or hormone replacement therapy within 3 months before breast cancer diagnosis

  10. Concomitant use of anticancer mediations other than those specified for use by the protocol

  11. Prior neoadjuvant or adjuvant endocrine therapy since diagnosis of breast cancer

  12. History of treatment for osteopenia/osteoporosis or baseline bone mineral density Z-score ≤ -2.0

  13. Prior (within 6 months prior to Day 1) or current use of drugs known to increase bone mineral density (ie, bisphosphonates, denosumab, teriparatide, abaloparatide, romosozumab) or use of supplements known to increase bone mineral density (ie, calcitonin, fluoride, strontium) within 28 days prior to Day 1

  14. 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)

  15. 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)

  16. 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

  17. Already receiving and/or previously received GnRH analogs within 1 year before breast cancer diagnosis

  18. Psychiatric, addictive, or other disorders that would preclude study compliance

  19. Use of medications that may impact subject safety and/or affect the PK of the drug and hormonal assessments including but not limited to:

    1. Oral or transdermal hormonal therapy within 30 days prior to subject's first visit
    2. Estrogen, progesterone, or androgens within 30 days prior to subject's first visit
    3. Hormonal contraceptives within 30 days prior to subject's first visit
    4. Medications known to result in clinically important decreases in bone mass taken within 6 months prior to subject's first visit
