A Liquid-biopsy Informed Platform Trial to Evaluate Treatment in CDK4/6-inhibitor Resistant ER+/HER2- Metastatic Breast Cancer

The purpose of the pre-study screening is to test for biomarkers. The testing will be done using a sample of your blood. Patients will be sorted into one of the substudies, depending on eligibility and availability. Each substudy will be looking at what effects a new drug has on the patients and their breast cancer, as well as any side effects of the treatment. The purpose of each substudy is to see if the biomarkers that were identified at screening can be used to determine treatment outcomes, like how the cancer cells respond to treatment.


Complexity Level: 1

Eligibility: Patients (>=18yrs old, ECOG PS 0-1), life expectancy >=3 mo., must have advanced/metastatic ER+/HER2- breast cancer as per ASCO/CAP criteria that have objective progression on first line CDK4/6i+ET. One subsequent line of endocrine or target therapy is allowed. Pts may have received adjuvant/neoadjuvant systemic therapies; palliative cytotoxic chemotherapy is not permissible. All reversible prior toxicity related to prior therapies must have recovered to grade =<1 and have adequate washout. Measurable disease per RECIST 1.1. Consent to release of tissue block and biopsies. Women/men of childbearing potential must have agreed to use an effective contraceptive method. No history of other malignancies or uncontrolled /serious illnesses which would not permit the patient to be managed per protocol. Hypersensitivity to any of the study drug components. No CNS metastases. No pts who are unable to swallow oral meds/have impairment of GI function. No history of non-compliance.

Objectives: Primary: Centrally genotype ctDNA from patients with CDK4/6i+ET resistant ER+/HER2- metastatic breast cancer and evaluate whether biomarker selection improves outcomes as assessed by RECIST 1.1 overall response rate (ORR), or for select studies, clinical benefit rate (CBR). Secondary: Evaluate safety and toxicity of each substudy drug and summarize progression free and overall survival. Exploratory: Create and maintain a tissue/data bank for patients undergoing screening for enrollment to a treatment substudy, evaluate changes in liquid biopsy ctDNA and CTCs as surrogates of treatment outcomes, evaluate potential biomarkers of response, resistance and progression through exploratory corelative studies.

Liquid-Biopsy Monitoring for Patients not yet Eligible for Screening and Enrollment

The purpose of this study is to monitor and follow your progress through your standard treatment. To do this, tumour tissue and blood samples will be tested for biomarkers, and imaging scans will be looked at to see how they are responding to standard treatment. If progression occurs (cancer gets wose) and the patient needs to start other treatment, the patient may be able to take part in the main treatment portion of the IND.241 trial.


Complexity Level: 1

Eligibility: Patients (>=18yrs old), life expectnacy >=3 mo., must have advanced/metastatic ER+/HER2- breast cancer as per ASCO/CAP criteria that are on or about to initiate active treatment with standard first-line therapy with a CDK4/6 inhibitor combined with an aromatase inhibitor.Pts. who have progressed on, or within 12 mo. of completion of adjuvant therapy with an aromatase inhibitor may be treated with fulvestrant instead of an aromatase inhibitor.. Measurable disease per RECIST 1.1. Consent to release of tissue block and biopsies. Not pregnant or breastfeeding. No history of other malignancies or uncontrolled /serious illnesses which would not permit the patient to be managed per protocol. Hypersensitivity to any of the study drug components. No CNS metastases. No pts who are unable to swallow oral meds/have impairment of GI function. No history of non-compliance.

Objectives: Primary: To create and maintain a tissue and data bank including tumour and liquid biopsies and clinical data for patients receiving first line endocrine therapy plus CDK4/6i treatment.

Tailor RT: A Randomized Trial of Regional Radiotherapy in Biomarker Low Risk Node Positive and T3N0 Breast Cancer

Women with node positive breast cancer normally will receive endocrine therapy and some may receive chemotherapy to help prevent the cancer from coming back. Many women will also receive radiotherapy to the whole breast/chest area and the surrounding lymph glands (called regional radiotherapy). No one really knows whether patients with low risk breast cancer need to receive regional radiotherapy. Some women may be getting regional radiotherapy who do not need it. These women may be exposed to the side effects of their treatment without benefit. The purpose of this study is to compare the effects on women with low risk breast cancer of receiving usual care that includes regional radiation therapy, with receiving no regional radiation therapy. Researchers want to see if not giving this type of radiation treatment works as well at preventing breast cancer from coming back.


Complexity Level: 2

Eligibility: 1) Newly diagnosed histologically proven invasive carcinoma of the breast with no evidence of metastases. 2) Must have been treated by BCS or mastectomy with clear margins of excision. 3) Patients with T3N0 disease are eligible. 4) Patients with disease limited to nodal micrometastases are eligible. 5) If treated by an axillary dissection must have 1-3 positive axillary nodes. 6) If treated by a SLNB alone must have only 1-2 positive axillary nodes. 7) Must be ER greater than or equal to 1% and Her2 negative on local testing. 8) Must have an Oncotype DX recurence score of 25 or less. 9) Must consent to provision of tissue and blood for mandatory correlative studies 10) Must have had endocrine therapy initiated or planned for greater than or equal to 5 years 11) ECOG performance status must be 0,1 or 2. 12) Age must be greater than or equal to 35 years.

Objectives: Primary: To compare the breast cancer recurrence-free interval (BCRFI) between patients that received regional RT or not, defined as time from randomization to time of invasive recurrent disease in the ipsilateral chestwall, breast, regional nodes, distant sites or death due to BC. Secondary: 1) Invasive disease-free survival (DFS); 2) Breast cancer mortality; 3) Overall survival (OS); 4) Locoregional recurrence-free interval (LRRFI); 5) Distant recurrence-free interval (DRFI); 6) Toxicity; 7) Arm volume and mobility 8) Patient reported outcomes (PROs) and Quality of Life (QOL); 9) Cost effectiveness Tertiary: 1) To establish a comprehensive tumour bank; 2) To evaluate the ability of intrinsic subtype to predict study outcomes and the effect of regional RT on these outcomes; 3) To evaluate other radiation signatures to prognosticate and predict effect of regional RT; 4) To describe the prevalence of ctDNA and evaluate its prognostic ability

COMPASSHER2 Residual Disease (RD), A Double-Blinded, Phase III Randomized Trial of T-DM1 and Placebo Compared with T-DM1 and Tucatinib

The purpose of this study is to determine how well trastuzumab emtansine (T-DM1) and tucatinib work in preventing breast cancer from coming back (relapsing) in patients with high risk, HER2 positive breast cancer. T-DM1 is a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug, called DM1. Trastuzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as HER2 receptors, and delivers DM1 to kill them. Tucatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving T-DM1 and tucatinib may work better in preventing breast cancer from relapsing in patients with HER2 positive breast cancer compared to T-DM1 alone.


Complexity Level: 2

Eligibility: Confirmed HER2-positive breast cancer, who received neoadjuvant chemotherapy, have had total mastectomy with no gross residual disease at the margin of resection, or breast-conserving surgery with histologically negative margins of excision. Must have axilla evaluated with either sentinel node biopsy or axillary lymph node dissection. Patients must have adequate hepatic, renal, and bone marrow function. Patients must not be pregnant and not nursing, must be 18 years or older (male or female), and ECOG Performance Status of 1 or less.

Objectives: The primary objective is to determine if the iDFS with T-DM1 and tucatinib is superior to the iDFS in the control arm (T-DM1 + placebo) when administered to high-risk patients with HER2-positive breast cancer and residual disease after neoadjuvant HER2-directed therapy. Secondary objectives: (1) To evaluate whether treatment with tucatinib plus T-DM1 compared to treatment with T-DM1 alone (T-DM1 plus placebo) improves the following: overall survival (OS), breast cancer free survival (BCFS), distant recurrence-free survival (DRFS), disease-free survival (DFS), brain metastases-free survival (BMFS). (2) To evaluate whether treatment with tucatinib plus T-DM1 compared to treatment with T-DM1 alone (T-DM1 plus placebo) reduces the incidence of brain metastases.

A Randomized Phase III Trial of Paclitaxel Versus Paclitaxel Plus Bevacizumab (rhuMAb VEGF) as First-Line Therapy for Locally Recurrent or Metastatic Breast Cancer.


Eligibility: Patients must have histologically or cytologically confirmed adenocarcinoma of the breast with measurable or nonmeasurable locally recurrent or metastatic disease. Locally recurrent disease must not be amenable to resection with curative intent. All scans or x-rays used to document measurable or nonmeasurable disease must be done within 4 weeks prior to randomization. Patients with breast cancer overexpressing HER-2 (gene amplification by FISH or 3+ overexpression by immunohistochemistry) are not eligible unless they have received prior therapy with Herceptin. HER-2 testing is strongly encouraged. Therefore patients with unknown HER-2 status are not eligible unless the treating physician has determined that Herceptin-based therapy would be inappropriate or not indicated. Patients must not have had prior chemotherapy for locally recurrent or metastatic breast cancer. Prior hormonal therapy for locally recurrent or metastatic disease is allowed, but this must have been discontinued

Objectives: To determine the time to treatment failure of patients with chemotherapy naive metastatic breast cancer randomized to treatment with either paclitaxel alone or paclitaxel plus bevacizumab. To compare the objective response rate, duration of response, overall survival and time to progression of paclitaxel to that of the combination of paclitaxel plus bevacizumab.

A Phase III Trial Evaluating the Role of Chemotherapy as Adjuvant Therapy for Premenopausal Women with Endocrine Responsive Breast Cancer who Receive Endocrine Therapy


Complexity Level: 2

Eligibility: Premenopausal women with histologically proven, resected breast cancer with ER and/or PgR positive tumors for whom there is an uncertain role for adding chemotherapy to the adjuvant treatment program. Patients should be randomized within 12 weeks after surgery prior to commencing any adjuvant systemic therapy.

Objectives: This trial will evaluate the worth of adding adjuvant chemotherapy for premenopausal women with steroid hormone receptor positive early invasive breast cancer who receive ovarian function suppression plus either tamoxifen or exemestane for five years. The use of chemotherapy will be determined by randomization. The method of ovarian function suppression (GnRH analogue for five years, surgical oophorectomy or ovarian irradiation) and the choice of tamoxifen or exemestane will be determined by the investigator.

MAC8 (NSABP B-37)

A Randomized Clinical Trial of Adjuvant Chemotherapy for Radically Resected Loco-Regional Relapse of Breast Cancer.


Complexity Level: 2

Eligibility: Histologically proven local &/or regional recurrence of invasive breast cancer following primary treatment with mastectomy or breast conserving treatment. Surgical resection with radiotherapy (ro) or (ri). No evidence of distant mets. Measurement of hormone receptors in the recurrent tumour. Medically suitable for chemo of 3-6 months. Completed baseline QOL. Informed consent and agree to data and material transfer. Geographically accessible for f/u.

Objectives: Primary: To determine the efficacy of adjuvant chemotherapy, in terms of disease-free survival, in women with radically resected loco-regional relapsed breast cancer. Secondary: To determine systemic disease-free and overall survival; sites of recurrence, incidence of second (non-breast) malignancies, and causes of death without relapse of breast cancer; and to determine the quality of life of patients treated with this regimen.

MAP1

A Randomized Feasibility Study of Letrozole in Postmenopausal Women at Increased Risk for Development of Breast Cancer as Evidenced by High Breast Density


Eligibility: Healthy, postmenopausal women or those postmenopausal women who have had prior breast cancer with a receptor positive tumour, either ER or PR or equivocal or unknown breast cancer or who have had prior DCIS (receptor status not required), who have either not had adjuvant endocrine therapy or are more than six months from the completion of adjuvant endocrine therapy and who are eligible by virtue of the appearance of increased radiological density, grade 4, 5 or 6, on routine mammographic screening

Objectives: To determine the proportion of women who have a decrease in breast density of at least one grade after treatment for one year; to determine if the decrease in density grade is sustained one year after cessation of therapy; to evaluate specific changes related to other end-organ effects i.e. bone density, lipid metabolism, etc.

MAP2

A Randomized Study of the Effect of Exemestane (Aromasin) versus Placebo on Breast Density in Postmenopausal Women at Increased Risk for Development of Breast Cancer


Eligibility: Healthy, postmenopausal women who have increased radiological density occupying >25% of the breast tissue on routine screening mammogram.

Objectives: To determine whether treatment with exemestane for one year in women with spontaneously increased breast density leads to a decrease in breast density of at least >1 grade 12 months after randomization; to determine if the decrease in breast density grade is sustained one year after stopping treatment; to determine the correlation between the grade of breast density and bone density at base line and at 12 months; to assess overall safety (bone and lipid metabolism, toxicity); to compare menopause-specific quality of life.
