Brief Summary:
The purpose of this study is to test the safety and tolerability of PMD-026 in patients with metastatic breast cancer and triple negative breast cancer. PMD-026 is a targeted oral agent designed to kill tumor cells in metastatic breast cancer and triple negative breast cancer.

Condition or disease Intervention/treatment Phase
Metastatic Breast Cancer Triple Negative Breast Cancer Drug: PMD-026 Phase 1

Detailed Description:

This study will evaluate the safety and tolerability of PMD-026 using an accelerated titration design to define the MTD in metastatic breast cancer, followed by an expansion at the RP2D in triple negative breast cancer. All patients will receive daily oral doses of PMD-026 until either disease progression or unacceptable toxicity. Patients will have disease assessments initially after 6 weeks of treatment, and every 9 weeks thereafter.

Patients enrolled to the Dose Escalation Phase must have histologically or cytologically diagnosed metastatic breast cancer that has progressed on or after standard of care therapy. Patients enrolled to the Dose Expansion Phase must have histologically or cytologically diagnosed metastatic triple negative breast cancer from initial diagnosis (ER/PgR <1%, HER2 negative) that has progressed on or after standard of care therapy. All patients must provide tumor tissue (archival preferred) prior to study entry.

A subset (N=12) of patients in Part 2 of the study will participate in a 1- week evaluation of the effect of food on PMD-026 oral absorption.

PMD-026 is an oral, reversible small molecule inhibitor of RSK1-4 with high selectivity for RSK2. High levels of RSK2 expression have been associated with worse overall survival in breast cancer. Inhibiting RSK2 may inhibit growth of breast cancer.

Primary Outcome Measures :
  1. Incidence of Treatment-Emergent Adverse Events (Safety and Tolerability) [ Time Frame: Through study completion, an average of 12 weeks ]
    Toxicities will be assessed in each patient by tracking the occurrence of graded Adverse Events (AEs). AEs will be graded according to the National Cancer Institute Common Terminology for Adverse Events (NCI CTCAE) v5.0.

  2. Maximum tolerated dose (MTD) of PMD-026 [ Time Frame: Up to 21 days ]
    The MTD will be defined as the dose level at which no more than one of six patients experiences a dose limiting toxicity (DLT) after 21 days of treatment have occurred, with the next higher dose having at least 2 of 3 or 2 of 6 patients experiencing a DLT.

  3. Recommended Phase 2 Dose (RP2D) of PMD-026 [ Time Frame: Up to 14 months ]
    The RP2D will be determined following the determination of the MTD and an overall assessment of safety as determined by the Safety Committee.

  4. Efficacy in Patients [ Time Frame: 6 weeks ]
    Anti-tumor activity (efficacy) will be assessed in all patients.


Secondary Outcome Measures :
  1. Plasma Concentration [ Time Frame: 24 hours ]
    The plasma concentration will be measured as part of pharmacokinetic (PK) testing.

  2. Time to Response [ Time Frame: 6 weeks ]
    The time to response will be evaluated by disease assessments.

  3. Duration of Response [ Time Frame: 6 weeks ]
    The duration of response will be evaluated by disease assessments from time of first response (CR or PR) to time of disease progression.

  4. Effect of food on PMD-026 PK [ Time Frame: 24 hours ]
    The effect of food on plasma concentration will be measured as part of pharmacokinetic (PK) testing.


Other Outcome Measures:
  1. RSK2 Expression [ Time Frame: 6 weeks ]
    RSK2 expression will be evaluated in breast cancer tissue through immunohistochemistry (IHC).

  2. PMD-026 Activity in Tissue [ Time Frame: 6 weeks ]
    PMD-026 activity will be evaluated in Lehmann subtypes in breast cancer tissue.

  3. RSK2 Expression and Response [ Time Frame: 12 weeks ]
    The relationship between RSK2 expression and response will be evaluated following RSK2 IHC and disease assessments.

  4. PMD-026 pharmacodynamics and RSK signaling [ Time Frame: 2 weeks ]
    PMD-026 pharmacodynamics will be evaluated on RSK signaling.
