Default Clinical Trials Updates

The registration of clinical trials prior to the start of a clinical trial is now extremely important part of the protocol. Here is a statement from International Committee of Medical Journal Editors on Clinical trial Registration
Quote:
Altruism and trust lie at the heart of research on human subjects. Altruistic individuals volunteer for research because they trust that their participation will contribute to improved health for others and that researchers will minimize risks to participants. In return for the altruism and trust that make clinical research possible, the research enterprise has an obligation to conduct research ethically and to report it honestly. Honest reporting begins with revealing the existence of all clinical studies, even those that reflect unfavorably on a research sponsor's product.
Unfortunately, selective reporting of trials does occur, and it distorts the body of evidence available for clinical decision-making. Researchers (and journal editors) are generally most enthusiastic about the publication of trials that show either a large effect of a new treatment (positive trials) or equivalence of two approaches to treatment (non-inferiority trials). Researchers (and journals) typically are less excited about trials that show that a new treatment is inferior to standard treatment (negative trials) and even less interested in trials that are neither clearly positive nor clearly negative, since inconclusive trials will not in themselves change practice. Irrespective of their scientific interest, trial results that place financial interests at risk are particularly likely to remain unpublished and hidden from public view. The interests of the sponsor or authors notwithstanding, anyone should be able to learn of any trial's existence and its important characteristics.
The case against selective reporting is particularly compelling for research that tests interventions that could enter mainstream clinical practice. Rather than a single trial, it is usually a body of evidence, consisting of many studies, that changes medical practice. When research sponsors or investigators conceal the presence of selected trials, these studies cannot influence the thinking of patients, clinicians, other researchers, and experts who write practice guidelines or decide on insurance-coverage policy. If all trials are registered in a public repository at their inception, every trial's existence is part of the public record and the many stakeholders in clinical research can explore the full range of clinical evidence. We are far from this ideal at present, since trial registration is largely voluntary, registry data sets and public access to them varies, and registries contain only a small proportion of trials. In this editorial, published simultaneously in all member journals, the International Committee of Medical Journal Editors (ICMJE) proposes comprehensive trials registration as a solution to the problem of selective awareness and announces that all eleven ICMJE member journals will adopt a trials-registration policy to promote this goal.
The ICMJE member journals will require, as a condition of consideration for publication, registration in a public trials registry. Trials must register at or before the onset of patient enrollment. This policy applies to any clinical trial starting enrollment after July 1, 2005. For trials that began enrollment before this date, the ICMJE member journals will require registration by September 13, 2005, before considering the trial for publication. We speak only for ourselves, but we encourage editors of other biomedical journals to adopt similar policies. For this purpose, the ICMJE defines a clinical trial as any research project that prospectively assigns human subjects to intervention or comparison groups to study the cause-and-effect relationship between a medical intervention and a health outcome. Studies designed for other purposes, such as to study pharmacokinetics or major toxicity (e.g., phase 1 trials), would be exempt.
The ICMJE does not advocate one particular registry, but its member journals will require authors to register their trial in a registry that meets several criteria. The registry must be accessible to the public at no charge. It must be open to all prospective registrants and managed by a not-for-profit organization. There must be a mechanism to ensure the validity of the registration data, and the registry should be electronically searchable. An acceptable registry must include at minimum the following information: a unique identifying number, a statement of the intervention (or interventions) and comparison (or comparisons) studied, a statement of the study hypothesis, definitions of the primary and secondary outcome measures, eligibility criteria, key trial dates (registration date, anticipated or actual start date, anticipated or actual date of last follow-up, planned or actual date of closure to data entry, and date trial data considered complete), target number of subjects, funding source, and contact information for the principal investigator. To our knowledge, at present, only www.clinicaltrials.gov, sponsored by the United States National Library of Medicine, meets these requirements; there may be other registries, now or in the future, that meet all these requirements.
Registration is only part of the means to an end; that end is full transparency with respect to performance and reporting of clinical trials. Research sponsors may argue that public registration of clinical trials will result in unnecessary bureaucratic delays and destroy their competitive edge by allowing competitors full access to their research plans. We argue that enhanced public confidence in the research enterprise will compensate for the costs of full disclosure. Patients who volunteer to participate in clinical trials deserve to know that their contribution to improving human health will be available to inform health care decisions. The knowledge made possible by their collective altruism must be accessible to everyone. Required trial registration will advance this goal.
The purpose of this thread is to update with new trials that are registered at various sources related to the foot, lower limb and podiatry.

Effectiveness of Intensive Lipid Modification Medication in Preventing the Progression of Peripheral Arterial Disease (The ELIMIT Study)
Quote:
Peripheral arterial disease (PAD) occurs when arteries become narrowed or hardened because of a build-up of plaque or fat deposits. PAD develops most often in arteries in the legs, which can result in reduced blood flow to the legs and feet, occasionally causing leg pain and fatigue. Early identification of PAD and treatment with lifestyle changes or medications can help to keep legs healthy and lower risk for heart attack and stroke, but endovascular or surgical procedures may be necessary for people with severe PAD. Even after endovascular intervention, PAD symptoms must be continually monitored to prevent the development and progression of blockages in the arteries. The best approach for monitoring symptoms is still undetermined. This study will compare the effectiveness of an intensive combination of lipid modifying medications versus standard lipid modifying medications in treating people with significant PAD who have had an endovascular intervention.

A Comparison of Steel and Bioabsorbable Screw Fixation of Lisfranc Foot Injuries
Quote:
I hypothesize that absorbable screw fixation of the foot's Lisfranc ligaments does not yield significant differences in postoperative foot stability, ligament function, and symptoms when compared to steel screw fixation. In addition, absorbable screw fixation of the Lisfranc ligaments offers the advantage that a second surgical procedure to remove the screw is not necessary.

This clinical trial has just been registered:
Insulin Infusion and Infectious Foot Ulcers(IIIFU)
Quote:
Normoglycemia is important for the outcome of surgical and medical conditions. Insulin infusions have been studied to achieve normoglycemia during these circumstances and have proved to be useful. Insulin given by subcutaneous injections has longer duration compared to intravenous given insulin which makes it more difficult to control. The hypothesis behind the trial is the concept that insulin infusion is more effective in reaching normoglycemia in diabetic subjects during foot ulcer infection and surgical wound infection.

The study evaluates a target controlled insulin infusion or conventional therapy as antidiabetic treatment during foot ulcer infection and surgical wound infection.
Secondary efficacy parameter will be hospital stay, laboratories for inflammation and oxidative stress.

The CARROT trial: CAllus Reduction Reinforcing Orthotic Therapy - the effectiveness of sharp scalpel debridement of callus as a component of complex long-term interventions for painful forefoot plantar callosities in patients with rheumatoid arthritis
Quote:
This is a randomised controlled trial (RCT) of patients with rheumatoid arthritis (RA) and painful forefoot plantar callosities receiving either debridement of painful forefoot plantar callosities plus conservative therapies or conservative therapies alone.

Hypothesis:
The addition of repeated sharp scalpel debridement of callus to a long-term care plan offers no greater reduction in pain or improvement in functional status than a low-risk, long-term care plan based on conservative self care, footwear advice, padding and/orthoses.

Study on the Role of Decompression of Lower Extremity Nerves for the Treatment of Patients With Symptomatic Diabetic Neuropathy With Chronic Nerve Compression (DNND)
Quote:
Potential candidates for the study are patients who have symptomatic painful diabetic neuropathy who have not responded to medical treatment (glucose control, pain medications) for at least one year and continue to have severe pain.

It is thought today that one third of patients with diabetic neuropathy may have superimposed nerve compression in the nerves in the leg, or in other words the nerves may be pressed by the surrounding tissue. This nerve compression is what might be contributing to the pain, and often loss of sensation at the bottom of your feet. The principle is similar to carpal tunnel syndrome which is pressure of a nerve in the wrist. Carpal tunnel syndrome is seen in 14-30% of patients with diabetes compared to 2% in the general population.

This study involves one year of close care and follow-up. As a part of this study, you will have regular evaluations by a foot care specialist from Physical Medicine and Rehabilitation, receive glucose management tips from a Diabetic Nurse Educator, and also have specialized, non-invasive testing in the Neurology department. The care that you would receive for being a part of this study is highly exceptional due to the various departments involved and their dedication to this research.

Initial data supports success rates at around 80% in terms of significant alleviation of pain and restoration of at least protective sensation and long term follow ups have suggested decrease in prevalence of infections, ulcerations, and amputations.

Quote:
The purpose of this study is to regain range of motion of the great toe with dynamic splinting which will help reduce great toe's pain and swelling.
Quote:
Device: Metatarsophalangeal Extension Dynasplint System
Dynamic Splinting utilizes the protocols of Low-Load, Prolonged-Duration Stretch (LLPS) with calibrated, adjustable tension to increase the Total End Range Time (TERT) to reduce contracture. This unit is worn for 30 minutes, three times per day, (while seated or resting in bed) totaling 1.5 hours per day.
Other: Standard of Care
The current standard of care in treating Hallux Limitus will be given to all patients regardless of randomized categorization, and this includes: analgesic and nonsteroidal anti-inflammatory drugs (NSAIDs), orthotics with medial stiffness, and reduction of great toe movement in motions such as kneeling or squatting with the toes in an extended position.

Phase II Combination Stem Cell Therapy for the Treatment of Severe Leg Ischemia (MESENDO)
Sponsored by: TCA Cellular Therapy
Quote:
The purpose of this research study is to compare in patients with double-sided claudication if the transplant of a combination of stem cells obtained from the bone marrow of the same patient will contribute to the formation of new blood vessels in one of the severly diseased ischemic limbs(legs)versus the control limb that receives a placebo product.

Limb Ischemia (LI) is a severe obstruction of the arteries which seriously decrease blood flow to the extremities (mainly feet and legs) and has progressed to the point of severe pain and even skin ulcers or sores.

LI needs conprehensive treatment since the condition will not improve on its own. The overall goal of treatment is to reduce pain and increase blood flow to improve symptoms or save the leg and feet. In many cases, current options for treatment including medications, surgery or endovascular procedures have not been successful.

In the last few years, investigators have explored therapies aimed to increase blood flow to the isschemic vessel by transplanting cells that will promote the development of new vessels in the diseased leg.

The study hypothesis is based on the concept that the process of formation of new blood vessels is complex and requires the participation of several types of stem cells and growth factors. The lack of any of these components will produce vessels which are immature and unable to provide appropriated blood supply to the leg.

Patients eligible to participate in the this study are those suffering from double-sided claudication with poor circulation or severe leg blockages, which are not candidates for surgical procudures.

Once the mixture of stem cells is prepared and the patient's bone marrow is ready, cells will be transplanted into the calf muscle of one the the diseased legs while the other diseased leg will recieve the placebo. Clinical study to evaluate and compare the effacacy of the stem cell transplant will be performed for six months post cell transplant.

This clinical trial has just been registered:
Comparison of Two Methods of Negative Pressure Wound Therapy
Quote:
The current standard for negative pressure wound therapy is the Vacuum Assisted Closure Device (VAC), a commercial system that utilizes a computerized suction pump to apply negative pressure to an open-cell poly-urethane foam dressing sealed over a wound. The VAC system is effective but has some drawbacks:

The system is expensive.
There us conflicting data about the effectiveness of VAC therapy for infected wounds.
VAC therapy is difficult to use (and frequently fails) in wounds with excess fluid drainage, and in wounds near body orifices.
Over the past 4 years, we have accumulated additional experience with negative pressure wound therapy using wall suction applied to sealed gauze dressings with about 30 patients. We call this method G-SUC and have used it when we have been unable to maintain a dressing seal with the VAC system (due to excess drainage or wound location), for management if infected wounds. We have found this method to be effective without any specific negative side effects.

Our specific aims are:

Compare the effectiveness of G-SUC and standard VAC therapy. Outcomes measured for each method will include the proportional change in wound size over 1 - 2 weeks.
Compare the effectiveness of G-SUC and VAC system in controlling wound infections as measured by the number of patients who are able to clear infection by 4 days.
Compare the failure of each method of therapy by documenting the number of dressing that cannot be maintained because of fluid or suction.
Measure and compare the cost of wound treatment with the two methods including direct cost and time spent at the bed side performing the dressing change.
Our hypotheses are:

G-SUC and VAC are equivalent for the treatment of uncomplicated wounds in the acute care, in-patient setting.
G-SUC is more effective than VAC for management of infected wounds.
G-SUC is more versatile than VAC, and functional G-SUC dressings can be maintained in situations where functional VAC dressings cannot.
Negative pressure therapy with G-SUC is less costly than VAC.

Ischemic Foot Ulcers: Is Intervention Better Than Wound Care Alone
Quote:
This research study will compare two approved standard of care treatment modalities for the management of ischemic foot ulcers. The ischemic foot ulcer (wound) on your foot is a result of a blocked artery in your leg. The wound can sometimes be healed with wound care alone, which includes dressing changes with creams and removing (debriding) the dead tissue. Alternatively, the significant narrowing or blockage in one of the arteries in your leg can be treated with several endovascular treatment techniques including:

angioplasty, also called percutaneous transluminal angioplasty (PTA) and/or
stent placement
atherectomy
The hypothesis of this study is that early endovascular or surgical intervention in subjects with moderate arterial insufficiency and a non-healing foot ulcer results in a higher overall incidence of wound healing in a significantly shorter period of time.

The Effect of Anti-Inflammatory Analgesics on Pain Following Hallux Valgus Surgery
Quote:
Purpose
The effects of NSAIDs and Coxibs on the formation of bone and fracture healing have been a matter of debate since long 1,2.

There is, however, limited data in humans and further prospective randomised studies are warranted. Rueben and Ekman studied in a prospective randomised double blind study the effects of celecoxib, a selective cox-II-inhibitor, on pain and bone healing following spine surgery. They found significant effects on reduction of pain and need for opioid analgesics postoperatively but could see no negative effects the numbers of "none-unions" at a 1-year follow up 3.

In a similar prospective randomised double-blind study design significant effects in reduction of pain and need for rescue analgesia was seen from the use of celecoxib in the perioperative multi-modal pain strategy for cruciate-ligament reconstruction and no negative effects could bee seen on six month follow-up of the strength of the reconstructed ligament 4,5.

The aim of the present study is to further study the effects of the perioperative use of etoricoxibe, a selective cox-II-inhibitor, in a prospective randomised double-blind study on bone healing, pain and need for rescue analgesia in patients undergoing elective Hallux Valgus surgery with a standardised surgical technique ad modum Turan.
