  • Association between serum concentrations of DS-8201a and Top1cc formation [ Time Frame: Up to day 1 of cycle 3 (each cycle is 21 days) or optionally, up to time of disease progression or restaging follow-up ]
    The association between serum concentrations of DS-8201a and Top1cc formation will be assessed by computing the sample correlation between the area under the DS-8201a serum concentration curve (AUC) and the initial change in Top1cc (from baseline to cycle 1 day 7 [C1D7]). Will also compute the sample correlation between the maximum serum concentration of DS-8201a and the initial change in Top1cc (from baseline to C1D7). These relationships will also be summarized graphically using scatterplots and overlaid LOWESS curves.
  • Incidence of adverse events [ Time Frame: Up to 30 days post-treatment ]
    Descriptive analyses of Common Terminology Criteria for Adverse Events data will be performed, as will analysis of anti-drug antibodies.
  • Overall response rate [ Time Frame: From the start of the treatment until disease progression/recurrence ]
    Will estimate the overall response rate (complete response + partial response) among eligible patients who have received at least one dose of DS-8201a. A 95% confidence interval for this response rate will also be computed. For this analysis, response classifications will follow Response Evaluation Criteria in Solid Tumors version 1.1 guidelines.

Descriptive Information
Brief Title  ICMJE Testing the Biological Effects of DS-8201a on Patients With Advanced Cancer
Official Title  ICMJE Pilot Study of DS-8201a Pharmacodynamics in Patients With HER2-Expressing Advanced Solid Tumors
Brief Summary This phase I trial studies the biological effects of DS-8201a on patients with HER2 positive cancer that has spread to other places in the body (advanced). DS-8201a works by binding to a protein called HER2 that is present on the surface of tumor cells. This allows DS-8201a to kill the tumor cells by damaging their deoxyribonucleic acid (DNA), resulting in tumor cell death. This study looks at how DS-8201a may affect the levels of certain proteins and immune cells in tumors and how well the drug works against tumor cells by examining cells from a small piece tumor taken before and after DS-8201a is given.
Detailed Description

PRIMARY OBJECTIVE:

I. To assess the effects of trastuzumab deruxtecan (DS-8201a) on total Top1 levels in biopsy specimens from patients with HER2-expressing advanced solid tumors, at early and late post-treatment time points, thereby establishing the degree and duration of DS-8201 target engagement.

SECONDARY OBJECTIVES:

I. To assess any associations between serum concentrations of DS-8201a and the effects of DS-8201a on total Top1 levels in tumor biopsy specimens.

II. To determine the safety and tolerability of DS-8201a administered intravenously every 3 weeks, in 21-day cycles, at a dose of 5.4 mg/kg.

III. To determine the overall response rate (complete response [CR] + partial response [PR]) for patients administered intravenously with DS-8201a every 3 weeks, in 21-day cycles, at a dose of 5.4 mg/kg.

EXPLORATORY OBJECTIVES:

I. To evaluate the effects of DS-8201a on CD8+ T cell infiltration and activation in tumor, tumor PD-L1 and HER2 expression, and DDR signaling (gamma H2AX, RAD51, and phosphorylated [p]NBS1) in biopsy specimens.

II. To examine genomic alterations in circulating tumor DNA (ctDNA) that may be associated with DS-8201a response or resistance.

III. To examine any associations between baseline tumor HER2 amplification or HER2 expression level and response to DS-8201a.

IV. To evaluate the effects of DS-8201a on tumor levels of HER2 and DDR-associated proteins.

V. To examine any tumor genomic alterations that may be associated with resistance to DS-8201a.

VI. To evaluate anti-drug antibodies following administration of DS-8201a.

OUTLINE:

Patients receive trastuzumab deruxtecan intravenously (IV) over 30-90 minutes on day 1. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 40 days.

  • 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
  • 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
  • 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
  • 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
  • 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:

  • 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
  • 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 Global Initiative for Obstructive Lung Disease [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.
  • Patients who have had radiation therapy within 4 weeks (or palliative stereotactic radiation therapy within 2 weeks)
  • Patients who have had a major surgery within 4 weeks
  • Patients who are receiving any other investigational agents
  • 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
  • Patients who have a history of severe hypersensitivity reactions to other monoclonal antibodies
  • 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
  • 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 electrocardiogram (ECG)
  • 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
  • Patients with an uncontrolled infection requiring IV antibiotics, antivirals, or antifungals
  • 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 (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
  • 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
  • Patients with uncontrolled intercurrent illness
  • 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
  • Patients are not allowed to receive chloroquine/hydroxychloroquine. Patients receiving chloroquine/hydroxychloroquine require a washout of > 14 days
