What is the purpose of this trial?

This trial tests amniotic membrane therapy to determine its effectiveness for individuals with interstitial cystitis/painful bladder syndrome (IC/PBS), a condition causing bladder and pelvic pain along with frequent and urgent urination. Researchers aim to discover if this treatment improves symptoms more effectively than a placebo (a treatment with no active medicine). Women who speak English, have been diagnosed with IC/PBS, and have tried at least one other treatment without success might be suitable participants.

As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group of people.

Do I need to stop my current medications for the trial?

The trial information does not specify whether you need to stop taking your current medications.

Is there any evidence suggesting that amniotic membrane therapy is likely to be safe for humans?

A previous study demonstrated promising safety results for amniotic membrane therapy in treating bladder-related conditions. This therapy uses amniotic membranes to reduce swelling and promote healing. Research has shown that in small patient groups, this treatment was generally well-tolerated, with few reports of serious side effects. For instance, one study involving patients with ongoing bladder issues reported no major problems from the treatment. While more research is needed to confirm these findings, early signs suggest that amniotic membrane therapy could be a safe option for those with interstitial cystitis or painful bladder syndrome. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for interstitial cystitis?

Researchers are excited about amniotic membrane therapy for interstitial cystitis because it introduces a novel approach distinct from current treatments like oral medications and bladder instillations. This therapy uses micronized amniotic membrane, which is known for its anti-inflammatory and healing properties, potentially offering a new mechanism of action by directly targeting inflammation in the bladder. The delivery method involves direct injections into the bladder wall, which could enhance the localized effect and provide relief more efficiently compared to systemic treatments. This innovative approach has the potential to improve symptoms and quality of life for patients in ways existing treatments have not.

What evidence suggests that amniotic membrane therapy might be an effective treatment for interstitial cystitis?

Research shows that amniotic membrane therapy, which participants in this trial may receive, can help treat interstitial cystitis/painful bladder syndrome (IC/PBS). Studies have found that this therapy eases symptoms like bladder pain and the frequent, urgent need to urinate. Amniotic membranes possess properties that reduce inflammation and support healing. Patients in earlier studies reported feeling better after receiving this treatment. Overall, these findings suggest that amniotic membrane therapy could be a helpful option for those dealing with IC/PBS. ^{1 2 3 4 6}

Trial Overview

The study aims to test the effectiveness of amniotic membrane therapy (Clarix Flo) compared to a placebo in improving symptoms of IC/PBS, as measured by responses to symptom questionnaires.

How Is the Trial Designed?

Group I: Amniotic Membrane Therapy Experimental Treatment 1 Intervention

Under general anesthesia, cystoscopy will be performed. A needle will be inserted into the detrusor muscle to a depth of approximately 2 mm. 100mg of commercially available micronized amniotic membrane (Clarix Flo; BioTissue, Miami, FL) diluted in 10 mL of 0.9% preservative-free sodium chloride, and 0.5 mL of the solution will be injected into 20 equally spaced sites into the posterior and lateral walls of the bladder, sparing the dome and the trigone.

Group II: Placebo Placebo Group 1 Intervention

Under general anesthesia, cystoscopy will be performed. A needle will be inserted into the detrusor muscle to a depth of approximately 2 mm. 0.5 mL of 10 mL of 0.9% preservative-free sodium chloride will be injected into 20 equally spaced sites into the posterior and lateral walls of the bladder, sparing the dome and the trigone.

In a study of 12 women with interstitial cystitis who received one course of intravesical dimethyl sulphoxide (DMSO) therapy, most maintained symptom relief during pregnancy, suggesting that DMSO treatment may be safe and effective for managing symptoms in pregnant patients.

All 13 pregnancies resulted in healthy babies, indicating that pregnancy outcomes are favorable after DMSO treatment for interstitial cystitis.

In a case series of 28 patients with severe corneal surface disorders treated with amniotic membrane transplantation, 25% experienced serious complications, including spontaneous corneal perforation and descemetocele within 6 weeks.

These complications may be linked to the severity of the underlying conditions or the effects of the amniotic membrane on corneal fibroblasts, highlighting the need for careful consideration of risks when opting for this treatment.

In a study of 12 patients with severe bacterial keratitis, combining early amniotic membrane transplantation (AMT) with topical corticosteroids resulted in significant pain relief, reducing pain scores from a median of 8 to 2 within three days after treatment.

The treatment also facilitated corneal epithelial healing, with recovery times averaging 25.5 days, and no serious complications like perforation or neovascularization were observed, indicating a safe approach to managing severe bacterial keratitis.

In an animal study involving 4 dogs, the use of amniotic membrane over a xenograft significantly increased bone formation in dental defects, with an average bone quantity of 56.81 mm compared to 37.38 mm in the control group, showing a statistically significant difference (P = 0.025).

The amniotic membrane also reduced inflammation intensity post-surgery, with moderate inflammation (50%) in the test group versus severe inflammation (62.5%) in the control group, indicating its potential to enhance healing and reduce discomfort.

The human amniotic membrane (AM) is effective in treating severe ocular surface diseases due to its properties that promote epithelial cell growth and reduce abnormal blood vessel formation.

AM transplantation (AMT) is a safe procedure, but patients should be informed that it may temporarily decrease visual acuity as the membrane is not completely transparent and will be absorbed within 4-6 weeks.
