“These data reinforce the potential of EYSUVIS to transform the treatment landscape for dry eye disease,” said Dr.
“I’m pleased to hear the exciting news that EYSUVIS has successfully achieved the primary and key secondary endpoints in the STRIDE 3 clinical trial,” said Dr.
“We are thrilled with the results of STRIDE 3, which build on our prior clinical experience with EYSUVIS in our Phase 2, STRIDE 1 and STRIDE 2 trials,” said
If approved, Kala intends to commercialize EYSUVIS in
STRIDE 3 Topline Results:
STRIDE 3 was a multicenter, randomized, double-masked, placebo-controlled, parallel-arm study, comparing EYSUVIS to vehicle (placebo), each dosed four times a day (QID) for two weeks in 901 patients with dry eye disease. The ITT population consisted of 447 patients in the EYSUVIS treatment group and 454 patients receiving vehicle. Patients who met initial screening and inclusion/exclusion criteria then underwent a two-week run-in period with vehicle. Patients who continued to meet inclusion/exclusion criteria after the run-in were then randomized to receive either EYSUVIS or vehicle for two weeks. ODS was graded daily by the patient over the entire course of the trial using a visual analog grading scale (measured on a scale ranging from 0 to 100 mm) recorded in a patient diary.
STRIDE 3 achieved both of its independent primary endpoints, demonstrating a statistically significant reduction in the symptom endpoint of ODS from baseline to day 15 compared to vehicle control in both the overall ITT population (p=0.0002) and in a pre-defined subgroup of ITT patients with more severe baseline ocular discomfort (p=0.0007), defined as patients who scored greater than or equal to 68 mm in baseline ocular discomfort. These data replicate the achievement of both primary symptom endpoints of STRIDE 1 (p<0.0001 in the overall ITT population and p=0.0008 in the pre-defined ITT subgroup with more severe ocular discomfort at baseline). Statistical significance was also achieved in the key secondary endpoint of conjunctival hyperemia at day 15 in the ITT population (p<0.0001). This result replicates the achievement of the results of STRIDE 1 and STRIDE 2, where statistical significance was demonstrated for conjunctival hyperemia at day 15 in the ITT population as a prespecified primary endpoint in each of those trials. Statistical significance was also achieved for the key secondary endpoint of ODS at day 8 in the ITT population (p=0.0282), which was consistent with STRIDE 1 (p=0.0011) and STRIDE 2 (p=0.0408). Significant improvement was also observed for corneal staining in the ITT population (p=0.0042), consistent with the result in STRIDE 2 (p=0.0314).
EYSUVIS was well-tolerated in this trial, consistent with prior clinical trials. The most common adverse event observed in STRIDE 3 was instillation site pain, which was reported by 2.9% in the EYSUVIS group compared to 1.5% in the vehicle group. Elevations in intraocular pressure (IOP), a known side effect with topical corticosteroid administration, were similar between the two groups, with no patients in either the EYSUVIS or vehicle group experiencing an increase in IOP of 5 mmHg or greater that resulted in an IOP of greater than 21 mmHg in the study eye.

Kala is developing EYSUVIS (loteprednol etabonate ophthalmic suspension) 0.25% for the temporary relief of the signs and symptoms of dry eye disease utilizing a two-week course of therapy. Dry eye disease is a chronic, episodic, multifactorial disease affecting the tears and ocular surface and can involve tear film instability, inflammation, discomfort, visual disturbance and ocular surface damage. EYSUVIS utilizes Kala's AMPPLIFY™ mucus-penetrating particle (MPP) Drug Delivery Technology to enhance penetration of loteprednol etabonate (LE) into target tissue of the eye. Kala has completed one Phase 2 and three Phase 3 clinical trials, STRIDE 1, STRIDE 2 and STRIDE 3 (STRIDE - Short Term Relief In Dry Eye) for EYSUVIS. Kala believes that EYSUVIS' broad mechanism of action, rapid onset of relief of both signs and symptoms, favorable tolerability and safety profile and the potential to be complementary to existing therapies, could result in a preferred profile for the management of dry eye flares and other dry eye associated conditions.
Kala is a biopharmaceutical company focused on the discovery, development and commercialization of innovative therapies for diseases of the eye. Kala has applied its AMPPLIFYTM mucus penetrating particle Drug Delivery Technology to a corticosteroid, loteprednol etabonate (LE), designed for ocular applications, resulting in the
