Trial summary

The investigators propose a new therapeutic approach by injecting Botulinum Toxin Type A (BTA) to the oblique and transverse heads of adductor muscle of the great toe. BTA works by binding presynaptically to high-affinity recognition sites on the cholinergic nerve terminals and decrease the release of acetylcholine… Read more about this study

About this study

Official title: Therapeutic Effect of Botulinum Toxin Type A in Addition to Total Contact Insole in Treating Painful Hallux valgus-a Pilot Study

The investigators propose a new therapeutic approach by injecting Botulinum Toxin Type A (BTA) to the oblique and transverse heads of adductor muscle of the great toe. BTA works by binding presynaptically to high-affinity recognition sites on the cholinergic nerve terminals and decrease the release of acetylcholine, causing a neuromuscular blocking effect. The investigators hypothesize that BTA injection may help to decrease the hallux valgus angle by decrease adductor hallucis muscle activation. Thereby enhance the therapeutic result of hallux valgus treated with total contact insole. The outcome measurement may shed light in treating patient with painful hallux valgus and document evidence for plantar pressure changes in acute, sub-acute and chronic stage.

Read the detailed description

This is a randomized, double-blind, placebo-controlled prospective study to assess the influence and efficacy of intramuscular (IM) Botulinum Toxin Type A (BTA) injection in patients with painful hallux valgus with the use of total contact insole.

Fifty feet with painful hallux valgus will be collected. Informed consent is obtained according to the hospital's medical ethics and the human clinical trial committee. The feet will be randomized into 2 groups: Group A (n=25, treatment group) and Group B (n=25, control group). Clinical diagnosis of hallux valgus is made based on observation of great toe lateral deviation. Inclusion criteria were hallux valgus with angle of at least 20°, single or bilateral hallux valgus. To obtain the hallux valgus angle, foot roentgenography in AP and sesamoid views under the weight bearing condition will be obtained. The angle formed by lines drawn to bisect the first metatarsal bone and the proximal phalanx of the great toe will be measured. The exclusion criteria include history of foot operations, rheumatoid and gouty arthritis, and any contraindication to BTA administration. Subjective data such as the Foot Function Index will be collected.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing BOTOX and Normal Saline (0.9% NaCl) in people with Hallux Valgus, run by Chang Gung Memorial Hospital at 1 site in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Sep 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

hallux valgus angle (time frame: up to 18 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01501500, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Sep 2013.
