Brief Summary:
Rationale: Serum eye drops (SEDs) are used to treat patients with severe signs and symptoms of dry eyes and other corneal defects. Serum is used in severe ophthalmic cases where conventional treatment and/or eye drops (artificial tears) have insufficient effect. The use of SEDs in dry eye patients usually has a rapid effect. Most patients claim the effect to be instantaneous, and most symptoms improve within 48-72 hours.
There is evidence suggesting that substances in serum may help in the healing of epithelial defects, such as epidermal growth factor, fibroblast growth factor, fibronectin, and/or vitamin A. However, the precise serum factor responsible for alleviating the patient's complaints is currently not known.
SEDs are considered as a blood product under EU blood legislation (Directive 2002/98/EC), as well as in New Zealand and Australia. Commonly, autologous SEDs are used, but they are replaced more and more by allogeneic SEDs prepared from donor serum. Allogeneic SEDs are derived from healthy voluntary, non-remunerated male donors with blood group AB, and have the benefit of blood bank controlled quality. They can be delivered from stock and are therefore quickly available for each patient.
For application of eye drops, generally administration systems with a drop size of 40 to 50 µl are used, further on referred to as conventional sized eye drops. From previous studies done with medicinal eye drops, it has been shown that smaller eye drops, so called micro drops, can be just as effective and sometimes even superior to conventional drops for treatment of eye disease. If micro drops are just as effective or maybe even superior to conventional sized eye drops is currently unknown for the use of SEDs. This study will compare the feasibility and effectiveness of allogeneic serum micro eye drops using the mu-Drop applicator to the conventional sized allogeneic eye drops using the Meise applicator. Both systems have a closed manufacturing system.
Objective: The main objective is to determine whether the administration of allogeneic serum micro eye drops is non-inferior in terms of effectiveness and safety as compared to the conventional sized drops.
Main study parameters/endpoints: The primary endpoint is the improvement in OSDI score by using SEDs (OSDI score after treatment minus OSDI score before treatment), independent of the drop size, showing non-inferiority for the use of micro drops as compared to conventional sized drops.
