Details and patient eligibility

About

A one-year, randomized, attention placebo-controlled trial investigating the value of comprehensive adherence specific interventions, over the course of one year, to enhance adherence in both (a) newly diagnosed open-angle glaucoma, or ocular hypertension patients, naive to medical therapy and (b) those who have failed monotherapy with any prostaglandin analogue (and are therefore candidates for adjunctive therapy) who then are randomized to receive only travoprost monotherapy. Subjects will be randomized to two different interventions involving direct physician education, each of which will take approximately the same amount of physician time: The first will be intensive adherence education that will continue throughout the year. The second will be intensive eye care education, but without any direct adherence education. All patients participating in the study will be monitored for adherence by the TDA. The study will demonstrate for the first time the role of adherence-specific training in improving patient adherence and will validate the TDA in monitoring and improving adherence in glaucoma. This will correlate with prior work that has documented that greater adherence is associated with marked improvement in intraocular pressure (IOP) control. A second goal will be seeing whether improving adherence will change the course of glaucoma therapy by making therapeutic failures into therapeutic successes by reducing the need for adjunctive therapy using only monotherapy with travoprost.

Trial design

Primary purpose: Health Services Research

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: None (Open label)

---

107 participants in 2 patient groups, including a placebo group

A

Active Comparator group

Description:

Intervention will consist of intensive teaching on the nature of glaucoma, value of IOP control, need to adhere to medical therapy and counseling on the proper use of travoprost eye drops.

Treatment:

Device: TDA adherence monitor for travoprost therapy

B

Placebo Comparator group

Description:

Intervention with travoprost therapy and TDA monitoring. Patients of this arm will also be prescribed travoprost and will be followed up in a standard clinical fashion. This group will receive a comparable amount of personal physician attention, but will not be given adherence, or glaucoma education and will not be told that their adherence will be monitored. Their attention placebo intervention will discuss the importance and techniques of good "eye health" (sunglasses, vitamins, cataract development, etc but no details, or discussion of either glaucoma or adherence) will insure that the study results are not a result of a change in physician attention to a patient, per se, rather than adherence training.

Treatment:

Device: TDA and travoprost monotherapy
