Study of Dato-DXd and durvalumab in persistent triple-negative breast cancer

Recruting new patients

Select region:


    What is this study about?

    This trial is about testing a combination of new treatments for triple-negative breast cancer which hasn’t fully responded to the first line of treatment. The new treatment includes a drug called Dato-DXd and a known drug called Durvalumab, both administered individually, or as a combination. This is compared to an already established treatment recommended by the doctor. The researchers are mainly interested in delaying the return of the cancer, and if the new drug with or without Durvalumab does a better job at this than the doctor-recommended treatment. Along with this main goal, the trial will also monitor how these treatments affect patients’ routine activities, their well-being, their levels of fatigue, the amount of Dato-DXd and related components present in the body, and any side effects and potential risks associated with these treatments.

      Study Steps

      How Complex Will My Study Be and What Phases Will I Go Through?

      The steps a patient needs to take in this clinical trial depend on the arm they are allocated to. For example, in one of the arms labeled “Dato-DXd in combination with Durvalumab”:

      1. The patient will receive Dato-DXd at a dose of 6 mg/kg intravenously (IV) every 3 weeks (Q3W) for a total of 8 cycles.
      2. In combination with Dato-DXd, the patient will also receive Durvalumab at a dose of 1120 mg IV Q3W for a total of 9 cycles.

      Please let me know if you need detailed information for the other arms within this clinical trial.

      4. History of another primary malignancy except for adequately resected basal cell carcinoma of the skin or squamous cell carcinoma of the skin, in situ disease (including ductal carcinoma in situ) that has undergone potentially curative therapy, or other solid malignancy treated with curative intent with no known active disease within 5 years before randomisation and of low potential risk for recurrence.

      Please ensure you meet these disease-related criteria to be eligible to participate in the study.

      Terms and conditions

      What Requirements I Have to Meet To Join This Study?

      When Am I Eligible to Join the Study?

      Inclusion Criteria:

      1. Age: Participants must be ≥ 18 years at the time of screening.
      2. Histologically Confirmed Invasive TNBC: TNBC stands for Triple-Negative Breast Cancer, which is a type of breast cancer that does not have receptors for estrogen, progesterone, or HER2/neu, making it more challenging to treat. Confirmation is done via tissue analysis according to the ASCO/CAP (American Society of Clinical Oncology/College of American Pathologists) guidelines.
      3. Residual Invasive Disease: After completing neoadjuvant therapy, participants must have residual invasive disease in the breast and/or axillary lymph node(s) evident during surgical resection.
      4. Neoadjuvant Therapy Completion: Participants must have completed at least 6 cycles of neoadjuvant therapy featuring an anthracycline and/or a taxane, with or without platinum chemotherapy, and with or without pembrolizumab.
      5. No Evidence of Relapse: Participants should show no signs of locoregional (local) or distant (spread to other body parts) cancer relapse.
      6. Surgical Removal: All clinically evident disease in the breast and lymph nodes must have been surgically removed.
      7. ECOG Performance Status: ECOG stands for Eastern Cooperative Oncology Group, which is a scale used to determine the activity level and the ability to care for oneself. Participants must have a performance status of 0 (fully active, able to carry on all pre-disease performance without restriction) or 1 (restricted in physically strenuous activity but ambulatory and able to carry out work of a light or sedentary nature).
      8. Tumor Sample: All participants must provide a Formalin-Fixed Paraffin-Embedded (FFPE) tumor sample from the surgery of the residual invasive disease for tissue-based analysis.
      9. No Adjuvant Systemic Therapy: Participants must not be undergoing any adjuvant systemic therapy before the study.
      10. Radiotherapy Completion: If radiotherapy is applicable, it must be completed prior to the initiation of the study intervention.
      11. Randomization Timing: There are specific intervals mentioned between completion of radiotherapy or surgery and the date of randomization into the study, depending on whether the participant has undergone post-operative radiation therapy.
      12. LVEF ≥ 50%: Participants must have a Left Ventricular Ejection Fraction of at least 50%, which measures how much blood the left ventricle of the heart pumps out with each contraction. Assessment should be via Echocardiogram (ECHO) or Multigated Acquisition (MUGA) scan within 28 days before randomisation.
      13. Eligible for Therapy Options: Participants should be eligible for one of the therapy options listed as per the investigator’s assessment.
      14. No Known Germline BRCA Mutations: Participants should not have any known pathogenic mutations in BRCA1 or BRCA2 genes, which are associated with increased risk of breast and ovarian cancers.
      15. Adequate Bone Marrow Reserve and Organ Function: This criterion ensures that the participant’s body can tolerate the treatment. The assessment should be within 7 days before randomisation.

      If there is a term or criterion that hasn’t been explained clearly or if you have any further questions, please let me know.

      What Reasons Could Exclude Me from the Study?

      You cannot take part in the study if you meet any of the following conditions:

      1. Stage IV (metastatic) Triple-Negative Breast Cancer (TNBC): This means breast cancer that has spread beyond the original area to other parts of the body.
      2. History of prior invasive breast cancer: If you’ve had breast cancer that has spread into surrounding breast tissue, or evidence that cancer has returned after previous treatment.
      3. Severe or uncontrolled medical conditions: This includes systemic diseases, history of organ transplant, active bleeding diseases, ongoing or active infections, and chronic gastrointestinal conditions associated with diarrhea or previous complicated diverticulitis.
      4. Another primary malignancy: Except for certain treated skin cancers and in situ diseases which are cured and considered low-risk of recurrence.
      5. Persistent toxicities caused by previous anticancer therapy: Toxicities not improved to Grade ≤1, excluding hair loss. Some irreversible toxicities that won’t be worsened by the study may be allowed, like certain types of hearing loss.

      Investigational Medicinal Product

      What Products Are Being Used in This Study?

      The drugs involved in the study are:

      1. Pembrolizumab (Active Substance: Pembrolizumab): An antineoplastic agent belonging to the class of immune checkpoint inhibitors. It works by blocking the programmed cell death 1 (PD-1) receptor on lymphocytes, which may directly promote antitumor immune responses.
      2. Durvalumab (Active Substance: Durvalumab): Another antineoplastic agent that is also part of the immune checkpoint inhibitors class. Durvalumab targets the programmed death-ligand 1 (PD-L1) which can be expressed by tumor cells or other cells within the tumor environment, thereby enabling the immune system to detect and attack tumors.
      3. Capecitabine (Active Substance: Capecitabine): A prodrug that is enzymatically converted to 5-fluorouracil (5-FU) in the body. As an antimetabolite antineoplastic agent, it interferes with DNA production in cells, thereby inhibiting tumor growth.
      4. Dato-DXd (Datopotamab deruxtecan, also known as DS-1062a): An experimental drug provided in the study. It is a type of antibody-drug conjugate which delivers cytotoxic drugs directly to cancer cells. Dato-DXd is designed to target a protein commonly found in cancer cells and release a chemotherapy-like drug inside those cells to destroy them.

      These active substances are used to stimulate the participants’ immune response against tumor cells or directly interfere with the tumor cell’s functions.
