Brief Summary:
Phase 1 study to evaluate the safety and effect of Gedatolisib and PTK7-ADC for the treatment of triple negative breast cancer

Condition or disease Intervention/treatment Phase
Triple Negative Breast Cancer Metastatic Breast Cancer Drug: Gedatolisib Drug: PTK7-ADC Phase 1

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 18 participants
Intervention Model: Sequential Assignment
Intervention Model Description: Study will enroll 3 patients to the cohort 1 dose level. If 0 of 3 patients experience a DLT, the study will proceed to cohort 2. If 1 patient experiences a DLT, 3 additional patients will be enrolled into cohort 1. If 1 of 6 patients experience a DLT, the study will proceed and 3 patients will be enrolled to the cohort 2 dose level. If 0 patients experience a DLT in cohort 2, the study will proceed to cohort 3. If 1 patient experiences a DLT at cohort 2, 3 additional patients will be enrolled into cohort 2. If the study proceeds to cohort 3, 3 patients will be enrolled at this dose level. If 0 patients experience a DLT, the study will enroll an additional 3 patients at the cohort 3 dose level to better define the safety profile. If 1 of 3 patients experiences a DLT at cohort 3, 3 additional patients will still be enrolled into cohort 3. If 1 of 6 patients experience a DLT, the study will complete.

Arm Intervention/treatment
Experimental: Gedatolisb + PTK7-ADC Drug: Gedatolisib
Gedatolisb will be intravenously administered on Day 1, Day 8 and Day 15 of every 21 day cycle at a dose of 110 mg or 180mg depending on cohort assignment.

Drug: PTK7-ADC
PTK7-ADC will be administered on Day 1 of every 21 day cycle at a dose of 1.4mg/kg or 2.8 mg/kg depending on cohort assignment.
Other Name: PF-06647020




Primary Outcome Measures :
  1. Safety of Gedatolisb + PTK7-ADC using NCI CTCAE v4.0 [ Time Frame: through study completion i.e. up to 1 year ]
    safety and toxicity data will be assessed using NCI CTCAE v4.0 and tabulated and reported


Secondary Outcome Measures :
  1. Efficacy in all enrolled subjects [ Time Frame: 18 weeks ]
    efficacy as determined by clinical benefit at 18 weeks

  2. Overall response rate in all enrolled subjects [ Time Frame: through study completion i.e. up to 1 year ]
    efficacy as determined by overall response rate

  3. Progression free survival in all enrolled subjects [ Time Frame: through study completion i.e. up to 1 year ]
    efficacy as determined by progression free survival

  4. Pharmacodynamic determination of inhibition of PI3k signaling [ Time Frame: Cycle 1 Day 15 ]
    Pathological H-score will be determined from tissue obtained at screening and Cycle 1 Day 15. H-score will be compared to calculate percentage inhibition between samples.

  5. Pharmacodynamic determination modulation of Wnt pathway [ Time Frame: Cycle 1 Day 15 ]
    pathological H-score will be determined from tissue obtained at screening and Cycle 1 Day 15. H-score will be compared to calculate percentage change in expression between samples.

  6. Pharmacodynamic determination modulation of Wnt pathway [ Time Frame: Cycle 1 Day 15 ]
    RNA sequencing of tissue collected at screening and Cycle 1 Day 1 to compare Wnt pathway expression after treatment
