Oceana Therapeutics近日宣布了其填充剂NASHA® DX(商品名,Solesta ®)的一项随机对照临床试验结果。Solesta®是一种混悬于稳定透明质酸中的聚糖酐,经肛管粘膜下注射用于治疗大便失禁患者。该项发表在《柳叶刀》上的研究纳入了来自美国和欧洲的206例年龄在18-75岁的患者,达到其主要和次要终点,并显示了该疗法的疗效和安全性。

这项试验由Oceana Therapeutics和Q-Med AB赞助。2009年6月,Q-Med AB 给予Oceana Therapeutics Solesta全球独家销售权,并从此对产品的有效性和安全性对照研究进行合作。在研的Solesta采用了专有的NASHA技术,其是为保守治疗无效的大便失禁患者开发的一种微创治疗。Solesta是一种用于门诊患者无需麻醉的注射用凝胶。

2010年12月,美国食品和药物管理局(FDA)的胃肠病学和泌尿学器械专家小组推荐Solesta用于美国众多罹患大便(肠)失禁患者的治疗。

注射填充剂治疗可改善大便失禁症状,注射填充剂给药方法简单且安全、严重副作用少,当其他治疗不足以缓解大便失禁的症状时或可将其作为一种辅助/额外治疗,” Oceana Therapeutics首席医务官Howard Franklin博士说。”这意味着,注射填充剂为大便失禁患者带来了一种重要的新选择,其可以作为保守疗法(如饮食控制)和更侵袭性干预疗法(如手术)之间的过渡治疗手段。

Manufacturer:

Oceana Therapeutics, Inc.

Pharmacological Class:

Tissue bulking agent.

Active Ingredient(s):

Dextranomer microspheres 50mg/mL, sodium hyaluronate 15mg/mL; gel for submucosal inj.

Indication(s):

Treatment of fecal incontinence in patients who have failed conservative therapy (eg, diet, fiber therapy, anti-motility drugs).

Pharmacology:

Solesta is a biocompatible tissue bulking agent, consisting of dextranomer microspheres and stabilized sodium hyaluronate. While the exact mechanism of action has not been identified, it is hypothesized that Solesta may narrow the anal canal and allow for better sphincter control.

Clinical Trials:

Clinical data supporting the safety and effectiveness of Solesta are available from three clinical studies. The main body of clinical evidence came from a multi-center, prospective, randomized, Sham (placebo) controlled study of the product’s effectiveness and safety. The study included 206 patients (136 Solesta, 70 Sham) and consisted of a 6-month double-blinded phase followed by an open label phase in which patients originally randomized to Sham treatment were offered Solesta. The primary efficacy objective of the study required: 1) demonstrating a statistically significant Solesta effect after 6 months of treatment; 2) meeting a pre-defined threshold for clinical significance; and 3) showing durability of the Solesta benefit up to 12 months after treatment. All three of these endpoints were met. Additionally, patients have been followed for over 2 years and the corresponding data showed no decline in effectiveness.

Legal Classification:

Rx

Adults:

See literature. Bowel preparation of rectum using enema required prior to injection. Prophylactic antibiotics are recommended. Inject slowly in deep submucosal layer in the proximal part of the high pressure zone of the anal canal about 5mm above the dentate line. Four 1mL injections are to be given in the following order: posterior, left lateral, anterior, right lateral. Keep needle in place for 15–30 seconds to minimize leakage. A new needle should be used for each syringe and inj site. Post-treatment: Avoid hot baths and physical activity during first 24hrs, antidiarrheal drugs, sexual intercourse, strenuous physical activity for 1 week, anal manipulation for 1 month. Re-treatment: If needed, may repeat with max 4mL no sooner than 4 weeks after first injection. Point of injection should be made in between initial injections, shifted 1/8 of a turn.

Children:

<18yrs: not recommended.

Contraindication(s):

Active inflammatory bowel disease. Immunodeficiency disorders or ongoing immunosuppressive therapy. Previous radiation treatment to the pelvic area. Significant mucosal or full thickness rectal prolapse. Active anorectal conditions (eg, abscess, fissures, sepsis, bleeding, proctitis, other infections). Anorectal atresia, tumors, stenosis or malformation. Rectocele. Rectal varices. Presence of existing implant in anorectal region.

Warnings/Precautions:

Should only be used by physicians experienced in anorectal procedures who have successfully completed training and a certification program in Solesta inj procedure. Do not inject intravascularly; may cause vascular occlusion. Avoid inj in midline of anterior wall of rectum in men with enlarged prostate. Complete external sphincter disruption. Significant chronic anorectal pain. Previous anorectal procedures. Bleeding diathesis. Pregnancy. Nursing mothers.

Interaction(s):

Concomitant anticoagulants, antiplatelets: increased risk of bleeding at inj site.

Adverse Reaction(s):

Anal hemorrhage, anorectal discomfort, chills, diarrhea, inj site hemorrhage, pain.

How Supplied:

Syringe (1mL)—4 (w. needles)
