Brief Summary:

The purpose of this study is to find the highest dose of durvalumab that can be tolerated without causing very severe side effects when receiving standard treatment and to see what effects the study drug has on this type of cancer.

The researchers doing this study are also interested in looking for markers that will help predict which patients are most likely to be helped by durvalumab when receiving standard treatment and what effects durvalumab has on this type of cancer.

Condition or disease Intervention/treatment Phase
Metastatic Breast Cancer Drug: Durvalumab Drug: Trastuzumab Phase 1

Detailed Description:

The standard or usual treatment for this type of disease at this point is to receive a drug called trastuzumab that targets the HER-2 receptor. Durvalumab is a new type of drug for many types of cancer. This drug is an antibody and laboratory tests show that it works by allowing the immune system 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 a few people and seems promising but it is not clear if it can offer better results than standard treatment alone.

The use of durvalumab when receiving standard treatment is being studied because it is thought that one way of over-coming resistance to the standard therapy is to add a drug that activates the immune system, as durvalumab has been shown to do, thus "re-sensitizing" immune function to kill cancer cells.

Inclusion Criteria:

  • Patients must have histologically and/or cytologically confirmed HER-2 positive (assessed locally and by current ASCO/CAP criteria) breast cancer that is advanced/metastatic/recurrent or unresectable and for which no curative therapy exists.
  • Patients enrolled to the RP2D / expansion cohort must have accessible disease suitable for biopsy and have consented to biopsy prior to treatment and at the end of cycle 1. Paired biopsies are strongly recommended in all patients.
  • Presence of clinically and/or radiologically documented disease. All radiology studies must be performed within 28 days prior to registration (within 35 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 to longest diameter
    • Physical exam (using calipers) ≥ 10 mm
    • Lymph nodes by CT scan ≥ 15 mm to measured in short axis
  • Patients must be ≥ 18 years of age.
  • Patients must have an ECOG performance status of 0, 1, or 2.

Previous Therapy

  • Must have had prior exposure to a taxane, trastuzumab and pertuzumab* and preferably also prior exposure to TDM-1.

    • Taxane and pertuzumab may have been in the adjuvant or neoadjuvant setting.
    • Must not be eligible for further trastuzumab treatment per provincial / formulary guidelines (i.e. patient has had two prior lines of either trastuzumab or lapatinib).
    • Must have received at least one HER-2 based therapy in the palliative setting. * Note: exceptions to the requirement for prior pertuzumab may be given. Consult CCTG.

Cytotoxic Chemotherapy:

  • There is no limit to the number of prior regimens.

Other Systemic Therapy:

  • There is no limit to the number of prior regimens; however, patients may not have had prior immune therapies.
  • Patients must have recovered 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.
  • Radiation:

    • 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 registration. Exceptions may be made for low-dose, non-myelosuppressive radiotherapy after consultation with NCIC CTG. Concurrent radiotherapy is not permitted.
  • Surgery:

    • Previous surgery is permitted provided that a minimum of 28 days (4 weeks) have elapsed between any major surgery and date of registration, and that wound healing has occurred.

Female partners of a male subject must use a highly effective method of contraception throughout this period. Cessation of birth control after this point should be discussed with a responsible physician.
  • Subjects should not donate blood while participating in this study, or for at least 90 days following the last infusion of durvalumab, or until the time specified in the prescribing information of trastuzumab, whichever occurs longest.
  • Patient consent must be appropriately obtained in accordance with applicable local and regulatory requirements. Each patient must sign a consent form prior to registration in the trial and prior to tests which are considered to be study specific to document their willingness to participate.
  • Patients who cannot give informed consent (i.e. mentally incompetent patients, or those physically incapacitated such as comatose patients) are not to be recruited into the study. Patients competent but physically unable to sign the consent form may have the document signed by their nearest relative or legal guardian. Each patient will be provided with a full explanation of the study before consent is requested.
  • Patients must be accessible for treatment and follow up. Patients registered 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.

If test is positive, pregnancy testing may then include an ultrasound to rule-out pregnancy if a false-positive is suspected. For example, when beta-human chorionic gonadotropin is high and partner is vasectomized, it may be associated with tumour production of hCG, as seen with some cancers. Patient will be considered eligible if an ultrasound is negative for pregnancy.
