Background:

Sometimes solid tumors progress on standard therapy, or there is no standard therapy for them. Standard therapy for cancer is usually surgery, radiation, immunotherapy drugs, or chemotherapy. Researchers want to see if a drug called DS-8201a is better or worse than standard therapy for some cancers. DS-8201a binds to a protein called HER2 that is present on some cancer cells. DS-8201a damages the cancer cells DNA, which kills the cells.

Objective:

To learn how DS-8201a affects the levels of certain proteins and immune cells in tumors, and how well the drug works against the cancer cells in tumors.

Eligibility:

Adults age 18 and older with advanced cancer that expresses the HER2 protein.

Design:

Participants will be screened with a medical history and physical exam. Their tumor will be measured with computed tomography (CT) or magnetic resonance imaging scans. They will have heart tests and an eye exam. They will give blood samples.

Some screening tests will be repeated during the study.

Participants will get DS-8201a intravenously through an arm vein. It is given in 21-day cycles. They will get the drug for as long as their cancer does not get worse, they can tolerate the side effects, and they agree to stay on the study.

Participants will have biopsies to measure the effect of DS-8201a on their tumor cells and the immune cells within their tumor. The biopsies will be collected through a CT-guided procedure before participants start to get DS-8201a and twice while they are getting DS-8201a. They may have an extra optional biopsy if their tumor returns.

Participants will have a follow-up doctor s visit and call 40 days after treatment ends.

11. Patients who are Human Immunodeficiency Virus (HIV) positive may participate IF they meet the following eligibility requirements:

-They must be stable on their anti-retroviral regimen, and they must be healthy from an HIV perspective.

-They must have a CD4 count of greater than 250 cells/mcL over the past 6 months on this same anti-retroviral regimen and must not have had a CD4 count <200 cells/micro l over the past 2 years, unless it was deemed related to the cancer and/or immunotherapy-induced bone marrow suppression.

--For patients who have received chemotherapy in the past 6 months, a CD4 count <250 cells/microL during chemotherapy is permitted as long as viral loads were undetectable during this same chemotherapy.

- They must have an undetectable viral load and a CD4 count greater than or equal to 250 cells/microL within 8 days of enrollment.

- They must not be currently receiving prophylactic therapy for an opportunistic infection and must not have had an opportunistic infection within the past 6 months. HIV-infected patients should be monitored every 12 weeks for viral load and CD4 counts.

12. For patients with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated.

13. Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load.

14. Patients with treated brain metastases are eligible if follow-up brain imaging after central nervous system (CNS)-directed therapy shows no evidence of progression for greater than or equal to 1 month after treatment of the brain metastases.

15. Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial.

16. The effects of DS-8201a on the developing human fetus are unknown. For this reason and because HER2 antibodies conjugated to topoisomerase 1 inhibitor agents are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control or abstinence) prior to study entry and for the duration of study participation and for at least 7 months after the last dose of study drug. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of DS-8201a administration.

17. Women of non-child-bearing potential defined as pre-menopausal females with a documented tubal ligation or hysterectomy; or postmenopausal defined as 12 months of spontaneous amenorrhea (in questionable cases, a blood sample with simultaneous follicle-stimulating hormone [FSH] >40 mIU/mL and estradiol <40 pg/mL [<147 pmol/L] is confirmatory) are eligible. Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the contraception methods outlined for women of childbearing potential if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of post-menopausal status prior to study enrollment. For most forms of HRT, at least 2-4 weeks 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 post-menopausal status, they can resume use of HRT during the study without use of a contraceptive method.

18. Subjects must not freeze, donate, or retrieve for their own use ova or sperm starting at screening, throughout the study period, and for at least 4.5 months after the final study drug administration. Preservation of sperm or ova should be considered prior to enrollment in this study.

19. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with DS-8201a, breastfeeding should be discontinued if the mother is treated with DS-8201a.

EXCLUSION CRITERIA:

1. Patients who have had:

-Chemotherapy (including antibody drug therapy, retinoid therapy, hormonal therapy for cancer) within:

--4 weeks or five half-lives, whichever is shorter, for small-molecule targeted agents such as 5-fluorouracil-based agents, folinate agents, weekly paclitaxel or

--6 weeks for nitrosoureas or mitomycin C or

-Immunotherapy, including monoclonal antibody therapy, within 4 weeks.

2. Patients with any of the following pulmonary-related illnesses:

-A history of (non-infectious) interstitial lung disease (ILD)/pneumonitis that required steroids, current ILD/pneumonitis, or for whom suspected ILD/pneumonitis cannot be ruled out by imaging at screening.

-Clinically severe pulmonary compromise resulting from intercurrent pulmonary illnesses including, but not limited to, any underlying pulmonary disorder (i.e., pulmonary emboli within three months of the study enrollment, severe asthma, severe chronic obstructive pulmonary disease (COPD) grade 3-4 per GOLD criteria, restrictive lung disease, pleural effusion, etc.), and any autoimmune, connective tissue, or inflammatory disorders with potential pulmonary involvement (i.e., Rheumatoid arthritis, Sjogren's, sarcoidosis, etc.), or prior pneumonectomy.

3. Patients who have had radiation therapy within 4 weeks (or palliative stereotactic radiation therapy within 2 weeks).

4. Patients who have had a major surgery within 4 weeks.

5. Patients who are receiving any other investigational agents.

6. Patients with a medical history of myocardial infarction within 6 months before enrollment, symptomatic congestive heart failure (CHF) (New York Heart Association Class II to IV), or with troponin levels consistent with myocardial infarction (as defined according to the assay manufacturer) 28 days prior to enrollment.

7. History of allergic reactions attributed to compounds of similar chemical or biologic composition to DS-8201a (e.g., other topoisomerase I inhibitors) or the inactive ingredients in the drug product.

8. Patients who have a history of severe hypersensitivity reactions to other monoclonal antibodies.

9. Patients with a Fridericia s formula corrected QT interval (QTcF) prolongation to >470 ms (females) or >450 ms (males) based on average of the screening triplicate 12-lead ECG.

10. Patients with spinal cord compression or clinically active central nervous system metastases, defined as untreated and symptomatic, or requiring therapy with corticosteroids or anticonvulsants to control associated symptoms.

11. Patients with an uncontrolled infection requiring IV antibiotics, antivirals, or antifungals.

12. Patients with 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 (e.g., Grade 2 chemotherapy-induced neuropathy) may be eligible per the discretion of the Investigator after consultation with the Sponsor Medical Monitor or designee. Subjects should no longer be symptomatic nor require treatment with corticosteroids or anticonvulsants and must have recovered from the acute toxic effect of radiotherapy

13. Patients with substance abuse or any other medical conditions that would increase the safety risk to the subject or interfere with participation of the subject or evaluation of the clinical study in the opinion of the Investigator.

14. Patients with uncontrolled intercurrent illness.

15. Patients with psychiatric illness/social situations that would limit compliance with study requirements.

16. Pregnant women are excluded from this study because DS-8201a is a HER2 antibody conjugated to a topoisomerase 1 inhibitor agent with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with DS-8201a, breastfeeding should be discontinued if the mother is treated with DS-8201a.

17. Patients are not allowed to receive chloroquine/hydroxychloroquine. Patients receiving chloroquine/hydroxychloroquine require a washout of > 14 days.
