Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

On the basis of empirical evidence and clinical practice, the investigators have developed a formula called Tumor-shrinking Decoction (TSD) used in the treatment of uterine fibroids (UFs). The investigators preliminary clinical observation has demonstrated the benefits of TSD in improving UFs.

TSD is composed of 15 individual Chinese medicines: Astragalus Membranaceus, Semen Coicis, Poria, Curcuma longa L, and Fritillaria Thunbergii Miq, Cassia twig, Pollen typhae, Resina draconis, Lithospermum erythrorhizon, Halloysitum Rubrum, Rhizoma Corydalis processed with vinegar, Hirudo, Calcined corrugated sub , Oyster Shell and Laminaria Japonica Aresch.

It is hypothesized that TSD can effectively reduce the fibroid size and improve the symptoms associated with UFs and the greater anti-tumor potency of TSD is associated with higher therapeutic doses.

To test this hypothesis, one 16-week, double-blind, randomized, two-dose trial will be conducted in patients with symptomatic UFs to determine whether the high dose (217 g/day) of TSD could produce significantly greater effects in reducing the fibroid size and improving its related symptoms and biochemical profiles compared to the lower dose (69 g/day).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Numerous Chinese medicine preparations have been shown to possess therapeutic potential in relieving uterine fibroids (UFs) symptoms and shrinking the volume of fibroids without significant adverse effects, although the clinical efficacy needs to be further confirmed with rigorously designed.On the basis of empirical evidence and clinical practice, the investigators have developed a formula called Tumor-shrinking Decoction (TSD) used in the treatment of UFs. The investigators preliminary clinical observation has demonstrated the benefits of TSD in improving UFs.

TSD is composed of 15 individual Chinese medicines. According to traditional Chinese medicine (TCM) doctrine, most UFs are developed due to the deficiency of vital energy and the stasis of blood, resulting in the formation of pathological massive tissues. Individual Chinese medicines constituting TSD can be classified into three classes based on TCM-defined pharmacological actions: (i) Tonifying qi and resolve phlegm: Astragalus Membranaceus, Semen Coicis, Poria, Curcuma longa L, and Fritillaria Thunbergii Miq; (ii) Resolve stasis, stopping bleeding and relieve pain: Cassia twig, Pollen typhae, Resina draconis, Lithospermum erythrorhizon, Halloysitum Rubrum, Rhizoma Corydalis processed with vinegar; and (iii) Softening hardness and dissipate binds: Hirudo, Calcined corrugated sub , Oyster Shell and Laminaria Japonica Aresch.

Indeed, the investigators previous studies of cultured cells and animals have revealed that TSD robustly inhibits fibroid cell growth and proliferation. The investigators therefore hypothesize that TSD can effectively reduce the fibroid size and improve the symptoms associated with UFs and the greater anti-tumor potency of TSD is associated with higher therapeutic doses.

To test this hypothesis, one 16-week, double-blind, randomized, two-dose trial will be conducted in patients with symptomatic UFs to determine whether the high dose (217 g/day) of TSD could produce significantly greater effects in reducing the fibroid size and improving its related symptoms and biochemical profiles compared to the lower dose (69 g/day).
