Efficacy and Safety of Sanyong Jiedu Granules in Treating Lumps-Type Non-Lactational Mastitis: A Prospective Multicentre Randomised Controlled Trial

To evaluate the efficacy and safety of Sanyong Jiedu Granules in treating non-lactational mastitis with lump formation, and to investigate the relationship between its clinical efficacy and treatment duration.

Study Overview

Detailed Description

This study is a randomised controlled trial comprising three phases: the screening phase, the treatment phase and the follow-up phase.

  1. Screening phase: A total of 210 patients with mastitis who were not breastfeeding and met the inclusion and exclusion criteria were enrolled in either the experimental group or the control group, with 70 patients in each of Experimental Group 1, Experimental Group 2 and the control group.
  2. Treatment phase:

    Experimental Group 1: San Yong Jie Du Granules group: San Yong Jie Du Granules were taken with boiled water, 10 g per dose, three times daily, for 56 consecutive days or until symptoms were completely resolved or stabilised;

    Experimental Group 2: San Yong Jie Du Granules + guideline-based medication group:

    Treatment regimen for plasma cell mastitis:

    Patients without cephalosporin allergy: Oral cefuroxime axetil tablets (brand name: Dalixin®), 250 mg twice daily + oral metronidazole tablets, 0.4 g three times daily, for 7-10 consecutive days; In addition, take San Yong Jie Du Granules, 10g three times daily, for 56 consecutive days or until symptoms have completely resolved or stabilised; For patients allergic to cephalosporins: Oral levofloxacin tablets, 0.5g once daily + oral metronidazole tablets, 0.4g three times daily, for 7-14 consecutive days; In addition, take San Yong Jie Du Granules three times daily, 10g per dose, for 5-6 days or until symptoms have completely resolved or stabilised;

    Treatment regimen for granulomatous lobular mastitis:

    Take oral methylprednisolone tablets (brand name: Metrol®), 20 mg once daily, for 14 consecutive days. Once symptoms have subsided, gradually reduce the dose every 1-2 weeks to 16, 12, 8, and 4 mg/day; In addition, take San Yong Jie Du Granules, 10 g three times daily, for 56 consecutive days or until symptoms have completely resolved or stabilised;

    Control group: Standard guideline treatment group, i.e. treatment is based on the 2016 'Expert Consensus on the Diagnosis and Treatment of Non-lactational Mastitis' issued by the Breast Health and Breast Disease Prevention and Control Working Group of the Women's Health Branch of the Chinese Preventive Medicine Association. The two main types of non-lactational mastitis-plasma cell mastitis and granulomatous lobular mastitis-are treated in accordance with the expert consensus respectively.

    Treatment regimen for plasma cell mastitis:

    For patients without cephalosporin allergy: oral cefuroxime axetil tablets (brand name: Dalixin®), 250 mg twice daily, plus oral metronidazole tablets, 0.4 g three times daily, for 7-10 consecutive days.

    For patients allergic to cephalosporins: oral levofloxacin tablets, 0.5 g once daily, plus oral metronidazole tablets, 0.4 g three times daily, for 7-14 consecutive days.

    Treatment regimen for granulomatous lobular mastitis:

    Oral methylprednisolone tablets (brand name: Metrol®), 20 mg once daily for 14 consecutive days; following symptom relief, the dose should be gradually reduced every 1-2 weeks to 16, 12, 8, and 4 mg/day, and continued for 56 days or until symptoms are completely resolved or stabilised.

    Prior to the completion of the primary efficacy endpoint assessment (i.e. before week 8 of treatment), no destructive surgical procedures aimed at lesion clearance are permitted in any group, except in cases meeting the criteria for initiation of salvage therapy.

  3. Follow-up points and time windows: 2 weeks (±1 day) after commencement of medication, 4 weeks (±2 days) after commencement of medication, and upon completion of treatment/discontinuation of medication (±4 days).
  4. Follow-up period: Follow-up points and time windows: 4 weeks (±7 days) after discontinuation of treatment, 3 months (±7 days) after discontinuation of treatment.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Overall Response Rate
Time Frame: 4 weeks after taking the medication, 8 weeks after taking the medication

4 weeks after taking the medication, 8 weeks after taking the medication

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Lump Size
Time Frame: Baseline, 4 weeks after drug administration and 8 weeks after drug administration
The maximum diameter (longitudinal diameter) of the target lesion is measured by the investigator through imaging examinations (with breast ultrasound as the preferred method). If multiple lesions are present, one largest lesion is selected as the target lesion for tracking.Evaluate the percentage change in the maximum diameter of the target lesion relative to baseline at 4 weeks and 8 weeks post-treatment.
Baseline, 4 weeks after drug administration and 8 weeks after drug administration
NRS Score
Time Frame: Baseline,2, 4, and 8 weeks post-treatment, and 1 and 3 months after discontinuation of medication
A 0-10 point numerical rating scale (NRS) was used, where 0 points indicated "no pain" and 10 points indicated "the most severe imaginable pain." Investigators guided patients to rate their pain intensity based on the average pain level over the past 24 hours during the visit.The relative changes in NRS scores from baseline were evaluated at 2, 4, and 8 weeks post-treatment and at 1 and 3 months after discontinuation of medication.
Baseline,2, 4, and 8 weeks post-treatment, and 1 and 3 months after discontinuation of medication
Course of the disease
Time Frame: Baseline, 2 weeks after medication initiation (D14±3 days), 4 weeks after medication initiation (D28±5 days), and at treatment completion (D56/withdrawal ±7 days)

Imaging complete response: Imaging evaluation demonstrates complete resolution of all target lesions; Clinical response: The mass persists without clinical symptoms such as redness, swelling, heat, or pain.

Imaging assessment: Breast ultrasound examinations were performed at baseline, 4 weeks after medication initiation (D28±5 days), and at treatment completion (D56/withdrawal ±7 days). Investigators assessed the size of target lesions based on ultrasound findings during follow-up visits.

Clinical examination: Record the maximum diameter of the mass (unit: cm), tenderness level (using the NRS scoring system), and severity of clinical symptoms (cutaneous erythema, tissue swelling, and localized heat sensation) at baseline, 2 weeks after medication initiation (D14±3 days), 4 weeks after medication initiation (D28±5 days), and at treatment completion (D56/withdrawal ±7 days).

Recurrence Rate
Time Frame: Recurrence of disease activity within three months of the end of treatment
The assessment is conducted by the investigator during the visit based on the results of imaging examinations and clinical examinations.
Recurrence of disease activity within three months of the end of treatment
The total dose of steroid hormones or antibiotics from the initiation to the completion of treatment
Time Frame: The calculation begins on the day of randomization for the subjects (denoted as Day 0) and continues until the completion of treatment (Day 56/withdrawal)

Administration of steroid hormone medications : Record the specific dosage, route of administration, and duration of treatment for each patient per administration. For glucocorticoids, calculate the equivalent total dose of prednisone concurrently.

Administration of antibiotics: Record the specific dosage, route of administration, and duration of medication for each patient per administration.

The calculation begins on the day of randomization for the subjects (denoted as Day 0) and continues until the completion of treatment (Day 56/withdrawal)
