1. Participant must be more than 18 years of age inclusive, at the time of signing the informed consent.
2. Patients who are willing and capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form.
3. Participants with pathologically documented breast cancer that:
- is unresectable or metastatic
- HER2-positive expression (IHC 3 positive or IHC 2 positive with ISH positive) as confirmed by laboratory assessment within last 1 year of study enrolment.
- was previously treated with an anti HER-2 based regimen
4. Adequate bone marrow function, within 14 d before enrolment
5. Adequate renal function within 14 d before enrolment.
6. Adequate hepatic function within 14 d before enrolment.
7. Adequate hepatic function within 14 d before enrolment.
8. Female subjects of reproductive/childbearing potential must agree to use a highly effective form of contraception or avoid intercourse during and upon completion of the study and for at least 7 mo after the last dose of trastuzumab deruxtecan. Male subjects must agree to inform all potential female partners that they are participating in a clinical trial of a drug that may cause birth defects. Male subjects must also agree to either avoid intercourse or that they and/or any female partners of reproductive/childbearing potential will use a highly effective form of contraception during and upon completion of the study and for at least 4.5 mo after the last dose of trastuzumab deruxtecan.
9. Non-childbearing potential is defined as pre-menopausal females with a documented tubal ligation or hysterectomy; or postmenopausal defined as 12 mo of spontaneous amenorrhea. Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use 1 of the contraception methods for women of childbearing potential if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of postmenopausal status prior to study enrolment. For most forms of HRT, at least 2 to 4 wk will elapse between the cessation of therapy and the blood draw; this interval depends on the type and dosage of HRT. Following confirmation of their postmenopausal status, they can resume use of HRT during the study without use of a contraceptive method.
10. Male subjects must not freeze or donate sperm throughout the study period beginning at Cycle 1 Day 1 and for at least 4.5 mo after the last dose of trastuzumab deruxtecan or Preservation of sperm should be considered prior to enrollment in this study.
11. Female subjects must not donate ova or retrieve them for their own use from the time of Screening and throughout the study treatment period, and for at least 7 mo after the last dose of trastuzumab deruxtecan.
1. Prior treatment with T-DXd
2. Uncontrolled or significant cardiovascular disease, including any of the following:
a. History of myocardial infarction within 6 months before enrolment
b. History of symptomatic congestive heart failure (New York Heart Association Class II to IV);
c. Corrected QT interval (QTc) prolongation to less than 470 ms (females) or less than 450 ms (male);
d. LVEF more than 50% within 28 d prior to treatment initiation.
3. Has a history of (noninfectious) ILD/pneumonitis that required steroids, has current ILD/pneumonitis, or where suspected ILD/pneumonitis cannot be ruled out by imaging at Screening.
4. Spinal cord compression or clinically active central nervous system (CNS) metastases, defined as untreated or symptomatic, or requiring therapy with corticosteroids or anticonvulsants to control associated symptoms.
- Subjects with clinically inactive brain metastases may be included in the study.
- Subjects with treated brain metastases that are no longer symptomatic and who require no treatment with corticosteroids or anticonvulsants may be included in the study if they have recovered from the acute toxic effect of radiotherapy. A minimum of 2 wk must have elapsed between the end of whole brain radiotherapy and study enrollment.
5. Has a history of severe hypersensitivity reactions to either the drug substances or inactive ingredients in the drug product or to other mAbs.
6. Uncontrolled infection requiring IV antibiotics, antivirals, or antifungals.
7. Known human immunodeficiency virus (HIV) infection or active hepatitis B or C infection.
8. Unresolved toxicities from previous anticancer therapy, defined as toxicities (other than alopecia) not yet resolved to Grade less than or equal to 1 or baseline. Subjects with chronic Grade 2 toxicities may be eligible per the discretion of the investigator after consultation with the Sponsor Medical Monitor or designee (eg, Grade 2 chemotherapy-induced neuropathy).
9. Therapeutic radiation therapy or major surgery within 4 wk before enrolment or palliative stereotactic radiation therapy within 2 wk before enrolment.
10. Systemic treatment with anticancer therapy (immunotherapy [non-antibody-based therapy], retinoid therapy, or hormonal therapy) within 3 wk before enrolment; antibody-based-anticancer-therapy within 4 wk before enrolment; or treatment with nitrosoureas or mitomycin C within 6 wk before randomization; or treatment with small-molecule targeted agents within 2 wk or 5 half-lives before enrolment, whichever is longer.
11. Participation in a therapeutic clinical study within 3 wk before enrolment (for small-molecule targeted agents, this non-participation period is 2 wk or 5 half-lives, whichever is longer), or current participation in other investigational procedures.
12. Pregnant, breastfeeding, or planning to become pregnant.
13. Clinically severe pulmonary compromise resulting from intercurrent pulmonary illnesses including, but not limited to, any underlying pulmonary disorder (ie, pulmonary emboli within 3 months of the study enrollment, severe asthma, severe chronic obstructive pulmonary disease [COPD], restrictive lung disease, pleural effusion etc), and any autoimmune, connective tissue or inflammatory disorders with pulmonary involvement (ie, rheumatoid arthritis, Sjögren’s, sarcoidosis etc), or prior pneumonectomy
