The Focus of the Study is to Assess the Effectiveness of Topical Ivermectin on Eliminating Eyelash Sleeves Clinical Trial
Treatment of Ocular Demodex Infestation With Topical Ivermectin Cream 1%
Patients with Demodex infestation of the eyelids will have the sleeves from both eyes cleaned off with microblepharoexfoliation. Afterwards, one eye will be randomly selected for treatment with topical ivermectin 1% cream. The treatment will be repeated on that eye 2 weeks later. Afterwards, the patients will present monthly for photographs of the eyelashes. The photographs will be reviewed by an ophthalmologist outside of our institution who will be blind to which eye was treated and independently grade the amount of sleeves in each eye. The follow-up will be for 6 months after the second treatment.
Informed Consent Form and Authorization to Use and Disclose Protected Health Information Sponsor / Study Title: Helm Vision Group / "Treatment of Ocular Demodex Infestation with Topical Ivermectin Cream" Principal Investigator: (Study Doctor) Craig Helm, MD Telephone: 661-259-3937 (24 Hours) Address: Helm Vision Group 27420 Tourney Rd. Suite 100 Valencia, CA 91355 Background and Purpose You are being asked to participate in this research study because you have been informed that you have an overgrowth of the eyelash mite (Demodex folliculorum). We expect to enroll 20 subjects in this study. Mites are small arthropods. Two of these species of mites are specific to humans and are named Demodex folliculorum and Demodex brevis. Demodex folliculorum lives within human hair follicles, whereas Demodex brevis lives in human sebaceous glands. It is not clearly understood how people get mites but the older one gets the more likely it is that mites will be present. Demodex mites have been determined to be a source of eye and eyelid problems for people of all ages, including children. Having Demodex overgrowth is not a result of poor hygiene. Normal face washing and even the use of baby shampoo lid scrubs do not kill the mites. Ultimately it is thought that everyone gets them, although not everyone seems to be bothered by them. However, they are a cause of suffering for many people. The presence of Demodex mites is can cause of chronic eyelid inflammation (blepharitis) as well as styes and chalazia (small lumps or cysts within the eyelid). Symptoms of blepharitis include eyelid irritation, redness and itching. Demodex may also be a cause of dry eye syndrome. The most commonly accepted treatment for eyelash mites involves the use of tea tree oil along the eyelash margin. This treatment though helpful does not usually result in elimination of the organism and can be very irritating depending upon the concentration of tea tree oil that is used. It is known that tea tree oil concentrations of at least 50% are required to kill the mites. Lower concentrations of tea tree oil are commercially available in eyelid wipes and may help to control the mite population but are insufficient to eradicate them. The purpose of this study is to evaluate the effectiveness of ivermectin cream 1% in eliminating the presence of Demodex infestation of the eyelash follicles. A secondary goal is to evaluate the effectiveness of ivermectin cream 1% in reducing the symptoms of dry eye if any. A third goal is to determine if study treatment with ivermectin 1% topical cream decreases the salinity of the tears. Ivermectin cream is FDA-approved for use in rosacea which is a common skin condition associated with redness that affects the face and upper chest. However, the FDA has not approved the use of ivermectin cream for the use of treating Demodex infestation of the eyelids. Therefore, the use of ivermectin cream in this study is investigational. What Will Happen During the Study? The study will randomly select one eye to be treated with anti-Demodex study treatment while the other eye will be designated as a control eye and will not be treated with the study treatment. Both eyes will have the eyelashes cleaned by microblepharoexfoliation (Blephex©). Blephex© is a treatment that uses a soft rotating foam brush soaked in a cleaning solution to remove the scale build-up along the eyelash margins. This build-up (or "biofilm") can constrict the opening of the oil glands (Meibomian glands) that are most important in lubricating the ocular (eye) surface. The Blephex© treatment also removes the debris left behind by the Demodex mites that encircles the base of the eyelashes which are infested. The Blephex procedure is performed after instilling a drop of anesthetic into the eyes. Each eyelid margin is then treated at the base of the eyelashes and lid margin to remove the scaly buildup along the lid margin and to remove the eyelash debris. The procedure takes less than 10 minutes to perform. Those eyes randomized to the study treatment group will then have the ivermectin cream 1% applied to the base of the eyelashes, eyelids and surrounding skin. The cream will be left in place for 10 to 15 minutes after which point the excess cream will be wiped from the lashes with a saline soaked gauze pad. At the initial or "baseline" visit each subject will complete a questionnaire which asks questions regarding dry eye and blepharitis symptoms. A TearLab® test will be performed to measure the saltiness of your tears. The TearLab® test involves taking a tiny sample of your tears from each eye and using a machine to analyze it and determine the salt content. This is used as a measure of the degree of dryness of your eyes. The test is painless. Photographs of the eyelashes of all four eyelids will then be taken to document the extent of the mite infestation of the eyelids. Mites often leave debris at the base of eyelashes. This debris is called "cylindrical dandruff" or "sleeves." Next, a Blephex© treatment will be performed to remove all of the debris that the mites leave around the eyelashes. Repeat photographs will then be taken to document the successful removal of the mite debris. Afterwards, subjects will be randomized into either the study treatment group or the control group. Study Treatment Group: Blephex© and study treatment with ivermectin 1% cream Control Group: Blephex© only. Subjects in the study treatment group will return 2 weeks later for a second application of ivermectin 1% cream. Photographs, TearLab® tests and the dry eye questionnaire will be repeated at the 2-week and monthly intervals from the date of study treatment for 6 months. The study will end after 6 months. At this point the control eye will be treated and both eyes treated if necessary. Risks, Side Effects, and/or Discomforts Ivermectin Ivermectin is a drug that has been in worldwide use since 1981 and has proven to be generally very safe. It is on the World Health Organization's List of Essential Medicines, the safest and most effective medicines needed in a health system. We are using ivermectin cream to avoid the risks associated with its oral use. However it is important that you are aware of all risks associated with ivermectin. Although oral ivermectin is considered to be safe, a single case of ivermectin-induced severe hepatitis was reported in Switzerland in 2006 using a single dose of 15 mg. The use of oral ivermectin has been also associated with the following side effects: - Fatigue (0.9% of subjects) - Abdominal pain (0.9%) - Anorexia (0.9%) - Constipation (0.9%) - Diarrhea (1.8%) - Nausea (1.8%) - Vomiting (0.9%) - Dizziness (2.8%) - Sleepiness (0.9%) - Vertigo (0.9%) - Tremors (0.9%) - Itching (2.8%) - Rash (0.9%) - Hives (0.9%) - Low white blood cell count (3%) - Elevated liver enzymes (2%) - Anemia It has also been reported that ivermectin can increase the effect of warfarin (blood thinners, such as Coumadin) when used together. The use of ivermectin cream has been associated with: - Burning - Itching - Redness - Stinging of the skin and eyes. In this study we will apply the ivermectin cream around the eyelids and leave it in place for 10 to 15 minutes. After this period we will remove the excess cream. In our experience to date we have had subjects experience ocular burning and temporary blurring of vision but no other side effects. The blurring of vision has been temporary and in no case interfered with safe driving. It is possible to have an allergic reaction of the skin to the ivermectin cream although we have not observed this. Absorption of the ivermectin into the body is assumed to be minimal. BlephEx© You may feel a tickling sensation during the procedure. The eyelid skin may be somewhat irritated afterwards for an hour or two. Unforeseen Risks Since the use of the study treatment is investigational, there may be other risks that are unknown. Additionally, there may be unknown risks to a pregnancy, embryo, or fetus if you or your female partner become pregnant. Study Expectations You will be enrolled in the study for a 180-day period. During the study period, you will be asked to refrain from using any other type of medicated pad to clean the eyelids and will not be allowed to use any product containing tea tree oil, including tea tree oil-containing soap on the face. Any prescribed glaucoma drops may be used as there are no anti-Demodex properties known with these medications. Antibiotic drops or steroid drops may be prescribed for other ocular conditions as the need arises and will not exclude you from participation in this study. Alternatives to Participation You do not have to be in this study to receive treatment for your condition. Please talk to the study doctor about your options before you decide whether or not you will take part in this study.
