HealiAid Collagen Wound Dressing in Patients Undergoing Breast Tumor Surgery

Official title

Safety Observation of HealiAid Collagen Wound Dressing in Patients Undergoing Breast Tumor Surgery: A Post-Market Clinical Trial

Overview

The goal of this clinical trial is to evaluate the safety of the collagen wound dressing (HealiAid) in breast tumor patients with surgical treatment. The main questions it aims to answer are: 1. To record the incidence of the postoperative complications and adverse events (AEs) after applying the HealiAid wound dressing in patients undergoing surgery for breast tumor. 2. To evaluate the patients' satisfaction and quality of life using the Breast Q questionnaire before surgery and at weeks 2, 12, 26, and 52 after the surgery. 3. To evaluate the patients' results of vital signs, hematology tests, tumor marker tests, breast ultrasonography, and mammography after the surgery. Participants will undergo a breast surgery. Within the surgery procedure, the tumor will be completely removed with a margin of 1-2 cm surrounding healthy tissue and the wounds will be cleaned properly before the patients receive the HealiAid Collagen Wound Dressing at treatment visit, and six follow up visits at week 1, 2, 4, 12, 26 and 52.

Detailed description

This study is an open label, multicenter post-market clinical follow-up study with a single arm group design. Included patients with confirmed diagnosis of breast tumor who are candidates for surgical treatment, including breast partial mastectomy (BPM), breast conserving surgery (BCS), sentinel lymph node dissection (SLND) and/or axillary lymph node dissection (ALND).

Within the surgery procedure, the tumor is completely removed with a margin of 1-2 cm around healthy tissue. Wounds are then cleaned properly before applying the HealiAid Collagen Wound Dressing. HealiAid is soft and pliable. It can be adjusted to the size of the wound, and it is recommended to apply one to four pieces per wound. HealiAid Collagen Wound Dressing will be kept in place until absorbed completely.

The rehabilitation and the related introduction postoperative will follow the hospital protocols, patients will be advised to mobilize the ipsilateral arm within a few hours after surgery.

Patients will be visited at weeks 1, 2, 4, 12, 26, and 52 after surgery and assessed for surgical site wound and AE assessment. Additionally, photographs of the breast appearance are taken post-surgery before discharge and at weeks 12, and 52 after the surgery. Patient's quality of life (QoL) and satisfaction are evaluated using the Breast-Q questionnaire on screening day, before surgery on day 1, and at weeks 2, 12, 26, and 52 after the surgery.

Vital signs including respiratory rate, pulse, blood pressure and temperature will be continuously measured during the patients' hospitalization period following the surgery, which is estimated to last up to 3 days.

For the follow up examination, the breast ultrasonography will be performed at week 2 and 26 and week 52, and mammography will be performed at week 52. The hematology test and Tumor marker test will be performed at week 26.

All hypothesis tests are two-sided, use α=0.05, if P\<0.05, it is considered statistically significant. For inferential statistics, comparison of quantitative data, use the t-test or Wilcoxon rank sum test. For count data comparison, use Chi-square test or Fisher's exact test. For continuous data comparison, use repeated measured ANOVA test. For main/significant safety indicators, consider the influence of center or other stratification factors and perform Pearson correlation test (with baseline data as covariates).

Interventions

Primary outcome measures

• Incidence of the postoperative complications and adverse events [Time frame: Day0 through out 52 weeks]

Secondary outcome measures (6)

• Satisfaction and quality of life [Time frame: before surgery and at weeks 2, 12, 26, and 52 after the surgery.]
• Number of participants with abnormal vital sign results [Time frame: From post-surgery until discharge, assessed up to 3 days.]
• Number of participants with abnormal laboratory tests results [Time frame: Week 26 after the surgery.]
• Number of participants with abnormal tumor marker test results [Time frame: Week 26 after the surgery.]
• Breast ultrasonography [Time frame: Weeks 2, 26, and 52 after the surgery]
• Mammography [Time frame: Week 52 after the surgery]

Eligibility criteria

Inclusion criteria

• Age 18-70 years old.
• Patients are diagnosed with a benign or malignant breast tumor, that tumor size of ≦ 5 cm and no distant metastasis assessed by the imaging (breast ultrasonography, mammography, or MRI) and pathologic examination within 12 weeks before screening. If a benign breast tumor is identified through imaging and subsequently removed via surgery performed after the subject's enrollment in the study, the pathology report from that surgery should be used instead of any previous report.
• Patients diagnosed with a breast tumor, or those with a history of radiation and chemotherapy, who are scheduled to undergo surgery such as partial mastectomy, breast-conserving surgery, sentinel lymph node dissection, and/or axillary lymph node dissection .
• Patients who understand and are able to comply with follow-up visits and treatment during the trial period.
• Patients who are willing and capable of providing written informed consent. Not a person subject to a sentence of guardianship or subject to judicial guardians.

• Have a history of severe allergies or are allergic to collagen.
• Collagen vascular disease.
• History of serious postoperative complications.
• Infected wound.
• Patients who require emergency surgery.
• Patients with coagulation dysfunction, such as abnormal preoperative coagulation time (prothrombin time (PT)>18 seconds or partial thromboplastin time (PTT) >50 seconds)
• Patients with untreated or unstable diabetes, that the fasting blood sugar >180 mg/dL or postprandial blood sugar >200 mg/dL.
• Patients with untreated or unstable chronic diseases, such as hypertension, hyperlipidemia, cardiovascular disease, stroke.
