- The stock price of Ocuphire Pharma Inc (NASDAQ: OCUP) increased by over 65% pre-market today. This is why it happened.
The stock price of Ocuphire Pharma Inc (NASDAQ: OCUP) – a clinical-stage ophthalmic biopharmaceutical company focused on developing and commercializing therapies for the treatment of refractive and retinal eye disorders – increased by over 65% pre-market today. Investors responded positively to the company announcing that the first subjects have been enrolled in the MIRA-3 Phase 3 pivotal trial evaluating Nyxol Eye Drops in the reversal of pharmacologically-induced mydriasis (dilation of the pupil).
And with 6 sites enrolling subjects within days of activation and 10 more sites expected to start screening shortly, top-line results from the MIRA-3 trial are expected in early 2022 (around the end of the first quarter).
MIRA-3 Trial Design for Nyxol
Nyxol is a proprietary, preservative-free, ophthalmic formulation of phentolamine mesylate designed to reduce pupil size by inhibiting or relaxing the iris dilator muscle. And MIRA-3 is a multi-center, randomized, parallel-arm, double-masked, placebo-controlled study of the safety and efficacy of Nyxol (0.75% phentolamine ophthalmic solution) to reverse pharmacologically-induced mydriasis in healthy subjects.
The MIRA-3 trial was designed to enroll approximately 330 subjects aged 12 and older. And after screening, eligible subjects are randomized 2:1 to one of the 2 treatment arms (Nyxol or placebo, respectively) and will receive 1 of 3 approved mydriatic agents approximately 1 hour prior to receiving study treatment drops.
The randomization will be 3:1:1 to a mydriatic agent (2.5% phenylephrine, 1% tropicamide, or Paremyd, respectively). And the primary efficacy endpoint is the percentage of subjects’ study eyes returning to ≤ 0.2 mm from baseline photopic pupil diameter at 90 minutes. The secondary endpoints include pupil diameter (at multiple time points from 30 minutes to 24 hours), accommodation, and a patient questionnaire, as well as new assessments of glare disability, glare tolerability, and pupillary response to light.
Ocuphire is collaborating closely on the Nyxol programs with leading clinical research organization Oculos Development Services (subsidiary of iuvo BioScience) — which has been instrumental in the successful completion of the first two RM trials. And the enrollment of these trials has been remarkably expeditious due to the straightforward trial design and the engagement of experienced optometry and ophthalmic practice sites. Together, there is a high degree of confidence to deliver top-line results in the first quarter of 2022 after just initiating in the middle of this quarter.
“The safety and efficacy of Nyxol for reversal of mydriasis have been demonstrated in our prior MIRA-1 Phase 2b and MIRA-2 Phase 3 clinical trials. Both of these trials successfully met their primary and multiple secondary endpoints with statistical significance. We know that over half of patients take 6 hours or longer, sometimes 24 hours, to return to their normal pre-dilated pupil size. Our prior data on Nyxol showed that 50% of patients returned to baseline by 90 minutes and 80% by 3 hours. A positive outcome in MIRA-3 comparable to the results achieved in MIRA-2 will position us to submit an NDA for Nyxol for reversal of mydriasis in late 2022. Successful completion of MIRA-3, as well as our planned smaller pediatric safety study, will bring the total number of patients treated with Nyxol to over 500, out of over 900 study subjects.”

“Providing the best care to my patients is my top priority. Therefore, I am eager to adopt treatments that enhance the patient experience. As a retinal specialist, there is simply no substitute for dilation when it comes to disease management and treatment, including chronic intravitreal injections for wet AMD or DME. With the ability to return many patients safely to baseline pupil diameter within an hour or two, Nyxol can provide substantial benefit. We dilate almost all of our patients, and I would be excited to offer Nyxol to my patients following dilation in order to optimize their care.”

“In current practice, to achieve an optimal examination of the retina, ophthalmologists and optometrists regularly dilate patients to perform monitoring and screening for diseases of the eye. Patients often complain after dilation, citing unwanted symptoms including photophobia, loss of accommodation, inability to read clearly, inability to return to work and subjective discomfort for hours. Other patients actually forgo dilation completely at annual visits, limiting our ability to perform a comprehensive exam. There are no currently approved treatments available, and it is exciting to see the steady advancement towards potential FDA approval for Nyxol. Nyxol is a drop that has demonstrated rapid reversal of dilation in dark and light irides. It can also be used to more quickly reverse the most commonly used mydriatic agents such as phenylephrine and tropicamide. Nyxol could be widely used in our clinical practices, which could increase dilated exams and promote better overall eye health in our patient population.”
