A Study of Ado-trastuzumab Emtansine (T-DM1)-Induced Peripheral Neuropathy in HER2-positive Breast Cancer Patients

November 18, 2025 updated by: Mayo Clinic

A Study of the Natural History of Ado-trastuzumab Emtansine (T-DM1)-Induced Peripheral Neuropathy in HER2-positive Breast Cancer Patients

Researchers plan to study the natural history of ado-trastuzumab emtansine (T-DM1)-induced neuropathy both in patients without any history of neuropathy or previous neurotoxic agent use and in patients who have such a history.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Probability Sample

Study Population

Patients planning to receive three or more doses of Ado-trastuzumab emtansine (T-DM1) for HER2-positive metastatic breast cancer or for earlier-stage breast cancer. Patients must have previously used neurotoxic antineoplastic agents (excluding previous use of T-DM1), have pre-existing chemotherapy-induced peripheral neuropathy (CIPN), or have peripheral neuropathy secondary to other causes. Patients must also plan to continue clinical follow-up at the same institution where they enter the study.

Description

Inclusion Criteria:

  • Planning to receive three or more doses T-DM1 for HER2-positive metastatic breast cancer (any line) or for earlier-stage breast cancer. The patient may have received one dose of T-DM1, prior to study entry if it has not been longer than 14 days since that dose and that the patient will be able to complete the required baseline questionnaire within 14 days of their first dose of T-DM1.
  • Patients with previous use of neurotoxic antineoplastic agents (excluding previous use of T-DM1), pre-existing CIPN, or peripheral neuropathy secondary to other causes will be able to be enrolled in the study.
  • The patient plans to continue clinical follow-up at the same institution, where the patient entered the study.
  • Provide informed consent.
  • Ability to complete questionnaire(s) in English by themselves or with assistance.

Exclusion Criteria:

  • Previous use of T-DM1
  • Concomitant use of other neurotoxic anticancer agents including cisplatin, carboplatin, oxaliplatin, docetaxel, paclitaxel, vincristine, eribulin, vinorelbine, thalidomide, lenalidomide, bortezomib, or epothilones. If the patient used any of these previously, then they must have been stopped for at least 7 days prior to study entry.
  • Current use of commonly used drugs for the treatment of peripheral neuropathy, including duloxetine, gabapentinoids (pregabalin and gabapentin), venlafaxine, nortriptyline, or amitriptyline (including use of these medications for things other than neuropathy). If the patient used any of these previously, then they must have been stopped for at least 7 days prior to study entry.

Design Details

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
HER2 Metastatic Group
HER2 Metastatic Setting (defined by breast cancer that has spread outside of the breast and the immediately draining lymph node regions; stage IV)
HER2 Adjuvant Group
HER2 Adjuvant Setting (defined by breast cancer that is not known to have spread outside of the breast and the immediately draining lymph node regions; stages I-III). The Adjuvant Setting includes patients receiving neoadjuvant therapy.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in chronic neuropathy symptoms
Time Frame: Baseline, approximately 22 months
Measured using the European Organisation of Research and Treatment of Cancer Quality of Life Questionnaire-Chemotherapy-induced peripheral neuropathy (CIPN) twenty-item scale (EORTC QLQCIPN20), a validated instrument designed to elicit cancer patients' experience of symptoms and functional limitations related to chemotherapy-induced peripheral neuropathy. The total score of CIPN20, each of the three subscale scores (sensory, motor, autonomic), and each individual item of the CIPN20 tool will be computed following standard scoring algorithm and converted into a 0-100 scale; higher scores indicate greater severity of neuropathy symptoms.
Baseline, approximately 22 months

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 12, 2023

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
