  • "Reproxalap demonstrates positive phase 3 results for dry eye"

    "Topical ocular reproxalap improved ocular dryness more than vehicle in the first part of a phase 3 trial, Aldeyra Therapeutics announced in a press release.

    The ongoing, adaptive, two-part, multicenter, randomized, vehicle-controlled, double-masked, parallel-group phase 3 RENEW trial compared 0.25% topical ocular reproxalap, a novel, small-molecule immune-modulating covalent inhibitor of reactive aldehyde species, and vehicle in patients with moderate to severe dry eye disease.

    The study’s first part, which included 422 subjects, aimed to confirm dosing regimen, endpoints and sample size for its second part.

    Patients in the constant dosing group received either four-times-daily reproxalap or vehicle for 12 weeks, while those in the induction-maintenance dosing group received four-times-daily reproxalap or vehicle for 4 weeks followed by twice-daily reproxalap or vehicle for 8 weeks.

    The induction-maintenance dosing group experienced greater activity vs. vehicle than the constant dosing group and therefore will advance to the second part of the RENEW trial, which is expected to start in the first half of 2020, the release said.

    “The rapid amelioration of symptoms followed by symptomatic control in the induction-maintenance dosing regimen supports the potential of reproxalap to treat a wide range of dry eye disease states, from severe flares to persistent symptoms,” David Clark, MD, chief medical officer of Aldeyra, said in the release. “In addition, consistent with our positive phase 3 results in allergic conjunctivitis, reproxalap is one of the first dry eye disease drugs to demonstrate activity in reducing ocular itching, a prominent symptom associated with dry eye disease exacerbation, which is especially common during allergy seasons.”

    Reproxalap was also statistically superior to vehicle in visual analog scale ocular endpoints for itching, foreign body sensation, discomfort, photophobia and pain."

      I think yes, in another article this new drug is compared to Restasis and Xiidra; both that are used to treat MGD as well.

      "Within the dry eye market, reproxalap has solid advantages that will distinguish it from the currently marketed drugs—in the US, Allergan’s Restasis (cyclosporine 0.05%) and Shire’s Xiidra (lifitegrast) are the only approved brands for dry eye syndrome and are well-established blockbusters. In comparison, reproxalap is a first-in-class therapy with a novel mechanism of action, with no significant side effects, and a rapid onset of action. Restasis can take up to six months to show its effects and both Restasis and Xiidra can cause a stinging sensation in the eye.

      Reproxalap’s positive Phase IIb data certainly is welcome news for dry eye patients and immediately boosted Aldeyra’s shares. However, Aldeyra may still face an uphill battle in trying to secure a strong position in the dry eye market. Reproxalap’s frequency of administration could be the main barrier to uptake, considering it is administered four times a day, while both Restasis and Xiidra are administered twice per day. Key opinion leaders (KOLs) interviewed for GlobalData’s Dry Eye Syndrome report highlighted that simplified administration frequency is a major unmet need in this market, and reproxalap is not expected to address this.

      In addition, Allergan and Shire have invested a significant amount into aggressive advertising campaigns for their respective brands, so a company like Aldeyra, which currently does not have a dedicated ophthalmology sales force, marketing team, or even the global reach of these big pharma companies, will be heavily reliant on a future partnership to fully realize the potential of reproxalap in a timely manner. Lastly, there are other late-stage pipeline drugs for dry eye that will challenge reproxalap’s uptake, namely RegeneRx’s RGN-259, which KOLs viewed to be the strongest pipeline asset for this market. Given the numerous market dynamics, reproxalap’s Phase III results and a partnership with an established pharma company will be crucial to establish this new player in the dry eye market"
