Description
Summary
The purpose of this study is to test the safety and tolerability of PMD-026 in patients with metastatic breast cancer. PMD-026 is a targeted oral agent designed to kill tumor cells in metastatic breast cancer.
Official Title
Ph 1/1b/2 Multicenter, Open-Label, FIH Dose Esc & Dose Exp Study to Assess Safety and Tolerability of Orally Administered PMD-026 as a Single Agent and in Combination in Patients With Metastatic or Locally Advanced (Inoperable) RSK2+ Breast Cancer
Details
Combination with fulvestrant (Part 3):
This study will prospectively enroll RSK2+ (≥75% nuclear staining with ≥2+ in staining intensity) HR+, and human epidermal growth factor receptor 2 negative (HER2-) patients to evaluate PMD-026 in combination with a standard dose and schedule of fulvestrant. Fulvestrant will be dosed per the package insert (500 mg IM, Day 1 and 15 of the first 28-day cycle, then Day 1 of every cycle thereafter) in combination with PMD-026 at the RP2D (200 mg, PO, Q12h) determined in the monotherapy phase of the study. Up to 20 patients will be enrolled with locally advanced or metastatic HR+/HER2- breast cancer previously treated with a CDK4/6 inhibitor in combination with endocrine therapy.
The combination regimen will have a safety lead-in cohort of 6 patients. The SRC will review the safety data after the sixth patient has been treated for at least 28 days. If determined to be safe, up to 14 additional patients will receive the combination for a total of 20 patients. A Bayesian safety monitoring rule will be used to evaluate the rate of DLTs during expansion. Specifically, the rule will be applied after data is available for the 6th DLT-evaluable patient.

Eligibility
You can join if…
Open to people ages 18 years and up
, Combination with fulvestrant (Part 3):
- Available archival or FFPE
- RSK2 positive (≥75% nuclear staining with ≥2+ in staining intensity) as assessed by central lab from available archival or fresh tumor tissue (FFPE).
- Histologically or cytologically diagnosed HR+, HER2- defined as both
- >1% expression of ER and/or PgR receptor
- ≤ 1+ by IHC for HER2, or FISH negative. If 2+ by IHC for HER2 combined with FISH negative
- Diagnosis of adenocarcinoma of the breast with evidence of either locally advanced disease not amendable to resection or radiation with curative intent or metastatic disease not amendable to curative therapy
- Must be appropriate candidates for endocrine therapy
- Previously received at least 1 line of endocrine therapy for MBC or had recurrence while on adjuvant endocrine therapy for locally advanced breast cancer
- Discontinued endocrine therapy at least 15 days prior to first dose of PMD-026
- At least 1 measurable target lesion as defined by RECIST v1.1
- Progression on or after treatment with a CDK4/6 inhibitor in combination with endocrine therapy inhibitor in the locally advanced or metastatic setting
- Has not received fulvestrant in the locally advanced or metastatic setting. Note: If prior to study entry, a patient initiates fulvestrant in combination with targeted therapy and becomes intolerant of the targeted therapy before progression, that patient may enroll if PMD-026 is initiated within 48 days of start of fulvestrant and no missed doses of fulvestrant occurred.
- Not eligible for an AKT or PI3K inhibitor
- Adequate hematologic, hepatic, and renal function as assessed by laboratory parameters
- Toxicity related to prior therapy resolved to at least Grade 1 (alopecia excepted) or to at least Grade 2 with prior approval of the Medical Monitor
You CAN'T join if...
