NCT03471663

Brief Summary

This is a phase I, open-label study of D-0502 single agent and D-0502 in combination with standard dose of palbociclib to assess the safety and tolerability, identify an MTD, and/or RP2D, evaluate the PK properties and evaluate preliminary anti-tumor activities in women with advanced or metastatic ER-positive, HER2-negative breast cancer.

Eligibility Criteria

Age18 Years+
Sexfemale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Histologically-proven, ER-positive, HER2-negative locally advanced, inoperable, and/or metastatic breast cancer.
  • Female patients with menopausal status:
  • i. Postmenopausal status defined as meeting at least one of the following criteria:
  • Have undergone a bilateral oophorectomy any time in life;
  • Age ≥60 years, or
  • Age \<60 years but have cessation of regular menses ≥12 months with follicle stimulating hormone (FSH) value \>40 milli-international units per milliliter (mIU/mL) and an estradiol value \<40 picograms per milliliter (pg/mL) (140 picomoles per liter \[pmol/L\]).
  • ii. Premenopausal or perimenopausal concurrently given a luteinizing hormone-releasing hormone (LHRH) agonist starting at least 4 weeks before the start of trial therapy and is planned to continue LHRH agonist during the study.
  • Patients meeting all the following criteria:
  • Has had at least 6 months of endocrine therapy for metastatic ER+ breast cancer prior to disease progression;
  • Limited number of prior chemotherapy, endocrine therapy, and targeted therapy for advanced or metastatic disease
  • Radiological or objective evidence of disease progression on or after the last systemic therapy prior to starting current study treatment.
  • For phase Ia: Not eligible for standard therapy that would confer clinical benefit to the patient.

You may not qualify if:

  • Patients with prior anticancer or investigational drug treatment within the following windows are excluded:
  • Participants with prior anticancer or investigational drug treatment within the following windows are excluded:
  • Any anti-cancer therapy (including endocrine therapy, chemotherapy, targeted therapy, etc.) less than 30 days before first dose of study treatment.
  • Any investigational drug therapy less than 28 days or 4 half-lives (whichever is shorter) prior to first dose of study treatment.
  • Patients with untreated or symptomatic or progressive central nervous system (CNS) metastases.
