Rhea-AI Filing Summary

Opus Genetics reported encouraging early results from its Phase 1/2 OPGx-LCA5-1001 trial of OPGx-LCA5, a gene therapy for Leber congenital amaurosis type 5. The treatment has been well tolerated in all six participants (three adults and three pediatric), with no ocular serious adverse events or dose-limiting toxicities and only mild, expected eye-related side effects not attributed to the study drug.

All three pediatric participants with severe baseline vision impairment showed improvements across several vision measures after a single subretinal injection, including an average 0.3 logMAR gain in visual acuity and more than a 1 log unit increase in cone sensitivity to red and blue light, alongside mobility and microperimetry benefits. In adults, improvements in visual acuity were sustained through 18 months. The company plans to meet with the U.S. Food and Drug Administration in the fourth quarter of 2025 to discuss these results and potential next steps for the program.

Positive

  • Early efficacy signals in small trial: All three pediatric participants with severe baseline vision impairment showed a 0.3 logMAR average visual acuity gain and >1 log unit cone sensitivity improvement after OPGx-LCA5 treatment.
  • Favorable safety profile so far: Six treated participants (three adults and three pediatric) had no ocular serious adverse events or dose-limiting toxicities, and ocular side effects were mild and anticipated.
  • Durability indication in adults: Combined adult data suggest visual acuity improvements were sustained through 18 months, supporting potential longer-term benefit in this early-stage study.

Negative

  • None.

Insights

Early OPGx-LCA5 data show safety and functional vision gains in a very small trial.

The company describes OPGx-LCA5 as well tolerated in six treated participants, with no ocular serious adverse events or dose-limiting toxicities. Reported ocular side effects were mild and expected, and not related to the study drug, which is important for a first-in-human gene therapy program targeting Leber congenital amaurosis type 5.

All three pediatric participants reportedly improved on multiple functional vision measures, including an average 0.3 logMAR visual acuity gain and more than a 1 log unit increase in cone sensitivity to red and blue light, plus mobility and microperimetry benefits. Adult participants showed visual acuity gains that were sustained through 18 months, suggesting durability within this limited dataset.

The company plans a meeting with the U.S. Food and Drug Administration in the fourth quarter of 2025 to review the OPGx-LCA5-1001 results and discuss next steps. Outcomes from that interaction, and additional data as the trial progresses, will shape how this early safety and efficacy profile may translate into later-stage development plans.

Item 7.01
Regulation FD Disclosure.

On September 30, 2025, Opus Genetics, Inc., a Delaware corporation (the “Company”), issued a press release announcing three-month data from the pediatric cohort and 18-month data from the adult cohort of its ongoing Phase 1/2 clinical trial (the “OPGx-LCA5-1001 Trial”) evaluating OPGx-LCA5, an investigational gene augmentation therapy for Leber congenital amaurosis type 5 (“OPGx-LCA5”). A copy of the press release is furnished herewith as Exhibit 99.1.

In connection with the foregoing, the Company announced that it would be discussing the OPGx-LCA5-1001 Trial, among other things, on a webcast and conference call on September 30, 2025. A presentation prepared for the purposes of the webcast and conference call is furnished herewith as Exhibit 99.2. The Company has also made the presentation available to investors on the “Events” section of the Company’s website at https://ir.opusgtx.com.

The information in this Item 7.01 of this Current Report on Form 8-K, and Exhibits 99.1 and 99.2, are furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), nor shall each be deemed incorporated by reference in any filing made by the Company under the Securities Act of 1933, as amended, or the Exchange Act, whether made before or after the date hereof, except as expressly set forth by specific reference in such a filing. The Company undertakes no obligation to update, supplement or amend the materials attached hereto as Exhibits 99.1 and 99.2.

Item 8.01
Other Events.

The Company reported positive data from the OPGx-LCA5-1001 Trial evaluating OPGx-LCA5. OPGx-LCA5 has been well tolerated in all six participants treated to date (three adults and three pediatric participants), with no ocular serious adverse events or dose-limiting toxicities observed. All ocular adverse events were mild in severity and anticipated, with no events related to the study drug. One pediatric participant had a pre-existing cataract that worsened at three months, attributed to the surgical procedure, which did not obscure improvements in retinal sensitivity.

Three pediatric participants with severe baseline vision impairment received a single subretinal injection of OPGx-LCA5. All three pediatric participants provided evidence of improvements across multiple measures of visual function, including a group average of a 0.3 logMAR improvement in visual acuity and a >1 log unit improvement in cone sensitivity to both red and blue light on full-field stimulus testing, with additional evidence of functional benefit on mobility testing and microperimetry. Additionally, the combined adult data from the three adult participants supports that improvements in visual acuity were sustained through 18 months. The Company expects to meet with the U.S. Food and Drug Administration in the fourth quarter of 2025 to discuss the OPGx-LCA5-1001 Trial results and next steps for the program.
