Prophylactic Aqueous Suppression +1 More for Glaucoma
Recruiting5 awardsPhase 4
Mississauga, Ontario
After implantation of an Ahmed glaucoma valve in patients with glaucoma, hyperencapsulation phase is an unwanted postoperative phenomenon, typically occurring with the free 3 months postoperatively. When this does occur, it is treated with aqueous suppressant eye drops. This study aims to determine if it is possible to reduce the rate of hyperencapsulation phase. Patients in the treatment group will receive aqueous suppressant eye drops before the hyperencapsulation phase starts. Treatment will be initiated once their intraocular pressure is above a pre-defined level, and will target a pre-defined range.

Latanoprost +2 More for Ocular Hypertension
Recruiting3 awards2 criteria
Sherbrooke, Quebec
Intraocular pressure (IOP) is considered to be the main risk factor for progression of glaucoma and therefore the main target of therapy. Pharmacologic treatment of glaucoma has changed considerably during the last decades due to the introduction of prostaglandin analogues. Three of these are commonly used in North America: latanoprost (Latanoprost T, Pfizer), Travoprost (Travatan TM, Alcon) and bimatoprost (Lumigan TM, Allergan). There have been several studies to evaluate their effectiveness. The three seem to be equivalent, according to the only study that has compared the molecules. Latanoprost is employed initially, due to its paucity of side effects when compared to the other two analogues. However, if it is not effective, several studies ahve shown that a result is possible using either travoprost or bimatoprost. No study has been conducted to date systematically comparing the three molecules in cases of resistance to latanoprost. In actuality, the investigators patients will receive treatment identical to current practice with the exception of the group continuing with latanoprost. Several studies confirm the benefit of changing prostaglandin analogues if the first has not signficantly decreased the IOP (Palmberg et al. 2004). Each prostaglandin has unique properties which may cause the mechanism of action to vary slightly among patients. (cf. Pharmacological Aspects) The goal of the study is thus to evaluate the efficaciousness of latanoprost, bimatoprost and travoprost in their IOP-lowering capacity in patients who do not initially respond to latanoprost.

Delray Beach, Florida
This trial tests a small device that releases medication inside the eye to help patients with high eye pressure due to glaucoma or ocular hypertension. The medication helps fluid drain from the eye, reducing pressure and preventing vision problems.
Rho-kinase Inhibitor
Netarsudil Ophthalmic +1 More for Normal Tension Glaucoma
Recruiting5 awardsPhase 4
Vestal, New York
Glaucoma is the second leading cause of blindness and the first leading cause of irreversible vision loss worldwide. The intraocular pressure (IOP) is the only modifiable risk factor for all the spectrum of glaucoma. Reducing IOP in glaucoma increases the likelihood of preventing progression of the disease and preserving the quality of life of the patient. Although prostaglandin analogs (PGAs) and prostamides (PMs) are de facto first-line treatment options for managing glaucoma, it is a common clinical experience to see their treatment effects plateau to a level beyond which no clinically significant IOP reduction is likely. It is also common to find minimal IOP treatment effects in the following conditions: patients with normal tension glaucoma (NTG), patients with thicker central corneal thickness (CCT), and patients with higher levels of corneal hysteresis (CH). CH is a possible proxy for the ability of the scleral tissue around the optic nerve to dissipate energy away from the optic nerve fibers. Netarsudil, a rho-kinase inhibitor was recently approved by the FDA for the treatment of glaucoma and ocular hypertension. There is a paucity of research on the efficacy of netarsudil in patients with NTG, thicker CCT, and higher levels of CH. This study aims to investigate the above issues by evaluating the efficacy of netarsudil and bimatoprost in subjects with NTG, thicker corneas, and higher levels of CH. Hypotheses * Netarsudil will have non-inferior efficacy compared to Bimatoprost in treating NTG. * Corneal thickness and corneal hysteresis will reduce the efficacy of netarsudil similar to bimatoprost in NTG. * Netarsudil will change corneal thickness and corneal hysteresis similar to bimatoprost in NTG.

Bimatoprost SR for Glaucoma
Recruiting2 awardsPhase 3
Sun City, Arizona
This trial tests a long-lasting eye medication called Bimatoprost SR. It is for people with certain eye conditions who can't use regular eye drops effectively. The medication works by helping fluid drain from the eye, reducing pressure. Bimatoprost has been widely used for glaucoma management, typically delivered via eye drops, but newer methods like sustained-release implants are being explored to improve efficiency.
Frequently Asked Questions
Do I need insurance to participate in a trial?
Almost all clinical trials will cover the cost of the 'trial drug' — so no insurance is required for this. For trials where this trial drug is given alongside an already-approved medication, there may be a cost (which your insurance would normally cover).
Is there any support for travel costs?
Many of the teams running clinical trials will cover the cost of transportation to-and-from their care center.
Will I know what medication I am taking?
This depends on the specific study. If you're worried about receiving a placebo, you can actively filter out these trials using our search.
How long do clinical trials last?
Some trials will only require a single visit, while others will continue until your disease returns. It's fairly common for a trial to last somewhere between 1 and 6 months.
Do you verify all the trials on your website?
All of the trials listed on Power have been formally registered with the US Food and Drug Administration. Beyond this, some trials on Power have been formally 'verified' if the team behind the trial has completed an additional level of verification with our team.
How quickly will I hear back from a clinical trial?
Sadly, this response time can take anywhere from 6 hours to 2 weeks. We're working hard to speed up how quickly you hear back — in general, verified trials respond to patients within a few days.
