Brief Summary:
This phase I trial identifies the side effects and best dose of DS-8201a and olaparib in treating patients with HER2-expressing cancers that have spread to other places in the body or cannot be removed by surgery or endometrial cancer. Olaparib is a drug that blocks an enzyme involved in many cell functions, including the repair of deoxyribonucleic acid (DNA) damage. Blocking this enzyme may help keep tumor cells from repairing their damaged DNA, causing them to die. DS-8201a is an antibody-drug conjugate. This agent has two components: an antibody component and a chemotherapy component. The antibody component is attached to the chemotherapy molecules. Upon administration of DS-8201a, the antibody targets and binds to tumor cells that have abundant HER2 (human-epidermal growth factor receptor 2), which is a protein on the surface of some tumor cells. The chemotherapy then enters the cells and blocks DNA replication in the tumor cells with abundant HER2, causing them to die. Giving DS-8201a and olaparib may shrink or stabilize the cancer.

Experimental: Treatment (trastuzumab deruxtecan, olaparib)
Patients receive trastuzumab deruxtecan IV over 30-90 minutes on day 1 and olaparib PO BID on days 1-21 or days 8-14 of each cycle. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients taking olaparib BID on days 1-21 undergo collection of blood samples at the following times: baseline, days 1, 2, 8, and 15 of cycle 1, day 1 of cycle 2, days 1, 8, and 15 of cycle 3, day 1 of cycle 4, day 1 of every fourth cycle after cycle 4 and then at treatment end. Patients taking olaparib BID on days 8-14 undergo collection of blood samples at the following times: baseline, days 1, 2, 8, 9, and 15 of cycle 1, days 1 and 8 of cycle 2, days 1, 8, and 15 of cycle 3, day 1 of cycle 4, day 1 of every fourth cycle after that, and at treatment end. Patients undergo biopsy at baseline, and then on day 3 or day 10 of cycle 1. Patients also undergo echocardiography and CT throughout the trial.

Primary Outcome Measures :
- Maximum tolerated dose/recommended phase 2 dose [ Time Frame: Up to 42 days ]Will be measured by Common Terminology Criteria for Adverse Events version (v) 5.0 and analyzed using descriptive statistics.
- Incidence of adverse events [ Time Frame: Up to 30 days post treatment ]
Secondary Outcome Measures :
- Objective response rate (ORR) [ Time Frame: Up to 30 days post treatment ]ORR will be evaluated by Response Evaluation Criteria in Solid Tumors (RESIST) 1.1 criteria to determine the best overall response for evaluable patients.
- Clinical benefit rate (CBR) [ Time Frame: Up to 30 days post treatment ]CBR will be evaluated by RESIST 1.1 criteria to determine the best overall response for evaluable patients.
- Duration of response (DOR) [ Time Frame: Up to 30 days post treatment ]DOR will be evaluated by RESIST 1.1 criteria to determine the best overall response for evaluable patients. DOR will be described using the method of Kaplan-Meier.
- HER2 expression [ Time Frame: At baseline ]HER2 expression on archival specimens will be analyzed using current American Society of Clinical Oncology (ASCO)/College of American Pathologists (CAP) breast cancer and gastric cancer scoring methods. The levels of HER2 expression (0, 1+, 2+, or 3+) will be determined and the number and percentage of patients in each category will be reported. Chi-squared test and regression modeling may be used to investigate any possible relationship of HER2 biomarker levels with anti-tumor efficacy.
- Plasma pharmacokinetic (PK) profiles [ Time Frame: Up to 30 days post treatment ]PK will be analyzed using descriptive statistics. Analysis of variance and regression model may be used to investigate any possible relationship of PK biomarker levels with anti-tumor efficacy
- Markers of deoxyribonucleic acid (DNA) damage response (DDR) [ Time Frame: At baseline and on-treatment ]Markers of DDR will be measured by multiplex IF in tumor specimens at baseline and on-treatment in patients with uterine serous carcinoma in the dose expansion cohort and correlating these markers with response.
Other Outcome Measures:
- HER2 expression [ Time Frame: Up to 30 days post treatment ]Correlation between HER2 expression, immunohistochemistry (IHC), and response may be evaluated by Chi-squared test and regression model.
- Formation of topoisomerase I cleaved complex formation (TOP1cc) in blood samples [ Time Frame: Up to 30 days post treatment ]Will measure the formation of formation TOP1cc in blood specimens and correlate with response in the dose escalation and in the dose expansion Will be analyzed using descriptive statistics.
- Formation of TOP1cc in tumor specimens [ Time Frame: At baseline and on-treatment ]Will measure the formation of TOP1cc in tumor specimens at baseline and on-treatment and correlate with response in patients with uterine serous carcinoma in the dose expansion. Will be analyzed using descriptive statistics.
- Changes in HER2 expression [ Time Frame: Baseline up to 30 days post treatment ]Will measure changes in HER2 expression over the course of treatment by IHC and immunoMRM and correlate with response in patients with uterine serous carcinoma in the dose expansion. Will be analyzed using descriptive statistics.
- Biomarkers of response and resistance [ Time Frame: Up to 30 days post treatment ]Will be analyzed using descriptive statistics.

To be eligible for this trial, patients should be better than class 2B
- The effects of DS-8201a and olaparib on the developing human fetus are unknown. For this reason and because HER2 antibody conjugated to a topoisomerase 1 inhibitor agents as well as PARP inhibitors are known to be teratogenic; thus, women of child-bearing potential and men must agree to use highly effective contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for at least 7 months (women of childbearing potential [WOCBP] only) 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 and olaparib administration
- 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 child-bearing 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
- Male subjects must not freeze or donate sperm starting at screening and throughout the study period, and at least 4 months after the final study drug administration. Preservation of sperm should be considered prior to enrollment in this study
- Female subjects must not donate, or retrieve for their own use, ova from the time of screening and throughout the study treatment period, and for at least 7 months after the final study drug administration
- Ability to understand and the willingness to sign a written informed consent document. Participants with impaired decision-making capacity (IDMC) who have a legally-authorized representative (LAR) and/or family member available will also be eligible
Exclusion Criteria:
- Patients who have had chemotherapy (including antibody drug therapy) within 4 weeks with the following exceptions: 1 week for weekly paclitaxel; 2 weeks or five half-lives, whichever is longer, for small-molecule targeted agents such as 5-fluorouracil-based agents, folinate agents, hormonal agents; or 6 weeks for nitrosoureas or mitomycin C
- Patients who have had radiation therapy within 4 weeks
- Patients who have had a major surgery within 4 weeks
- Patients who are receiving any other investigational agents
- For the dose expansion cohort: Patients who have received prior PARP inhibitors
- Patients with a history of (non-infectious) interstitial lung disease (ILD)/pneumonitis that required steroids, has current ILD/pneumonitis, or where suspected ILD/pneumonitis cannot be ruled out by imaging at screening
- Patients with 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], 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
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to DS-8201a, the inactive ingredients in the drug product, olaparib, or severe hypersensitivity to other monoclonal antibodies
- Patients receiving any medications or substances that are moderate or strong inhibitors or inducers of CYP3A are ineligible. Because the lists of these agents are constantly changing, it is important to regularly consult a frequently-updated medical reference. As part of the enrollment/informed consent procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product
- Patients with a medical history of myocardial infarction within 6 months before randomization/enrollment, symptomatic congestive heart failure (CHF) (New York Heart Association class IIb to IV), troponin levels consistent with myocardial infarction as defined according to the manufacturer 28 days prior to randomization
- Patients with a corrected QT interval (QTc) prolongation to > 470 ms (females) or > 450 ms (males) based on average of the screening triplicate 12-lead electrocardiogram (ECG)
- Patients with multiple primary malignancies within 3 years, except adequately resected non-melanoma skin cancer, curatively treated in-situ disease, and other solid tumors curatively treated
- Patients with an uncontrolled infection requiring IV antibiotics, antivirals, or antifungals
- Patients receiving chloroquine or hydroxychloroquine will require a washout period of >= 14 days to be eligible for the study
- Patients with unresolved toxicities from previous anticancer therapy, defined as toxicities (other than alopecia) not yet resolved to grade =< 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 (e.g., grade 2 chemotherapy-induced neuropathy)
- Patients with psychiatric illness/social situations that would limit compliance with study requirements
- 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. These potential risks may also apply to other agents used in this study
