Brief Summary:
The purpose of this study is to find out the effect that CFI-400945 and durvalumab have on breast cancer.

Condition or disease Intervention/treatment Phase
Breast Cancer Drug: CFI-400945 Drug: Durvalumab Phase 2

Detailed Description:

CFI-400945 is a new type of drug for breast cancer. Laboratory tests show that it works by blocking a specific protein called Polo-like Kinase 4 (PLK4) that is involved in cancer cell growth. CFI-400945 may slow down the growth of cancer cells or may cause cancer cells to die. This drug has been shown to shrink tumours in animals and has been studied in more than 60 patients. It appears to be well tolerated with few side effects. CFI-400945 seems promising but it is not clear if it can offer better results than standard therapy.

Durvalumab is a new type of drug for many types of cancer. Durvalumab is an immunotherapy drug and not a chemotherapy drug. Laboratory tests show that it works by allowing the immune system (PD-1 and PD-L1 interaction) to detect your cancer and reactivating the immune response. This may help to slow down the growth of cancer or may cause cancer cells to die. Durvalumab has been shown to shrink tumours in animals and has been studied in more than 6000 people. In laboratory studies, when used together with CFI-400945, results seem promising but it is not clear if it can offer better results than standard treatment alone. This is the first time that the combination of CFI-400945 and durvalumab has been tested in patients.

Inclusion Criteria:

  • Patients must have histologically and/or cytologically confirmed diagnosis of breast cancer, that is advanced/metastatic or unresectable, for which no curative therapy exists, and be negative for ER, PR and HER2 by ASCO/CAP criteria on the most recent sample. Patients with tumour with either low (< 10%) ER expression who are PR and HER2 negative, or ER and HER2 negative but with low PR (< 10%) may be enrolled after discussion and confirmation with CCTG
  • Only female patients will be enrolled
  • All patients must have a formalin fixed paraffin embedded tissue block (from primary or metastatic tumour) available and must have provided informed consent for the release of the block. At least 6 patients in Stage 1 and 10 in Stage 2 must have accessible disease suitable for biopsy, have provided informed consent for and be willing to undergo a tumour biopsy prior to treatment and again between cycle 3, Day 1-8.
  • Presence of clinically and/or radiologically documented disease. All radiology studies must be performed within 21 days prior to enrollment (within 28 days if negative).
  • All patients must have measurable disease as defined by RECIST 1.1. The criteria for defining measurable disease are as follows:

    • Chest x-ray ≥ 20 mm
    • CT scan (with slice thickness of 5 mm) ≥ 10 mm -> longest diameter
    • Physical exam (using calipers) ≥ 10 mm
    • Lymph nodes by CT scan ≥ 15 mm -> measured in short axis
  • Patients must be ≥ 18 years of age
  • Patients must have an ECOG performance status of 0 or 1
  • Patients must have a life expectancy of 3 months or longer
  • Laboratory Requirements (must be done within 7 days prior to enrollment) Absolute neutrophils ≥ 1.5 x 10^9/L Platelets ≥ 100 x 10^9/L Bilirubin ≤ 1.5 x ULN (upper limit of normal) AST and ALT ≤ 2.5 x ULN, ≤ 4.0 x ULN if patient has liver metastases Serum creatinine ≤ 1.5 x ULN or Creatinine clearance ≥ 50 mL/min
  • Patients must be able to swallow oral medications and have no known gastrointestinal disorders that may interfere with absorption (such as malabsorption).
  • Patients must have had at least 1 prior line of cytotoxic chemotherapy for breast cancer, in any setting, which must have included an anthracycline and a taxane (unless contraindicated). There is no limit to the number of prior chemotherapy regimens.
  • Patients may have received other therapies including endocrine therapy and/or targeted therapies (including CDK4/6 inhibitors and PARP inhibitors).
  • Patients may not have received prior immunotherapies of any kind, nor any agent targeting PLK4.
  • Patients must have recovered (to at least grade 0 or 1) from all reversible toxicity related to prior chemotherapy or systemic therapy and have adequate washout as follows: Longest of one of the following:

    • Two weeks,
    • 5 half-lives for investigational agents,
    • Standard cycle length of standard therapies.
  • Prior external beam radiation is permitted provided a minimum of 28 days (4 weeks) have elapsed between the last dose of radiation and date of enrollment. Exceptions may be made for low-dose, non-myelosuppressive radiotherapy after consultation with CCTG. Concurrent radiotherapy is not permitted.
  • Previous surgery is permitted provided that a minimum of 21 days (3 weeks) have elapsed between any major surgery and date of enrollment, and that wound healing has occurred.
  • Patient consent must be appropriately obtained in accordance with applicable local and regulatory requirements. Each patient must sign a consent form prior to enrollment in the trial to document their willingness to participate.
  • Patients must be accessible for treatment and follow-up. Patients enrolled on this trial must be treated and followed at the participating centre. This implies there must be reasonable geographical limits (for example: 1 ½ hour's driving distance) placed on patients being considered for this trial

  • Women of childbearing potential must have agreed to use a highly effective contraceptive method.
  • Women of childbearing potential will have a pregnancy test to determine eligibility as part of the Pre-Study Evaluation; this may include an ultrasound to rule-out pregnancy if a false-positive is suspected
  • Subjects should not donate blood while participating in this study, or for at least 90 days following the last infusion of durvalumab

Exclusion Criteria:

  • Patients with a history of other malignancies, except: adequately treated non-melanoma skin cancer, curatively treated in-situ cancer of the cervix, or other solid tumours curatively treated with no evidence of disease for > 2 years and which do not require ongoing treatment.
  • Patients with serious illnesses or medical conditions which would not permit the patient to be managed according to the protocol (including corticosteroid administration), or would put the patient at risk. This includes but is not limited to:

    • History of significant neurologic or psychiatric disorder which would impair the ability to obtain consent or limit compliance with study requirements.
    • Active infection requiring systemic therapy; (including any patient known to have active hepatitis B, hepatitis C or human immunodeficiency virus (HIV) or tuberculosis or any infection requiring systemic therapy).
    • Active peptic ulcer disease or gastritis.
