What You Need to Know Before You Apply

What is the purpose of this trial?

The purpose of this research study is to assess the ability of AMDX- 2011P to identify amyloid deposits in the retina of participants with Primary Open Angle Glaucoma (POAG).

Do I have to stop taking my current medications for the trial?

The trial protocol does not specify whether you need to stop taking your current medications.

What safety data is available for AMDX-2011P in treating glaucoma?

The safety data for AMDX-2011P, also known as omidenepag isopropyl, includes several studies. A 3-month study in Japanese patients with open-angle glaucoma evaluated its adverse reactions. A Phase 3 study assessed its safety in patients with primary open-angle glaucoma or ocular hypertension who did not respond well to latanoprost. Phase 2 studies demonstrated its tolerability in patients with primary open-angle glaucoma and ocular hypertension, identifying 0.002% as the optimal dose. The RENGE study assessed its long-term safety over 12 months in patients with open-angle glaucoma or ocular hypertension. ^{1 2 3 4 5}

Is AMDX-2011P a promising treatment for Glaucoma?

The information provided does not mention AMDX-2011P or its effectiveness for treating glaucoma, so we can't say if it's promising based on this data. ^{6 7 8 9 10}

What data supports the idea that AMDX-2011P for Glaucoma is an effective treatment?

The available research does not provide any specific data on the effectiveness of AMDX-2011P for Glaucoma. Instead, it focuses on other treatments like the XEN45 implant and Aurolab aqueous drainage implant. Without direct data on AMDX-2011P, we cannot conclude its effectiveness for Glaucoma based on the provided information. ^{11 12 13 14 15}

The Aurolab aqueous drainage implant (AADI) demonstrated a higher complete success rate (68.42%) compared to the Ahmed glaucoma valve (AGV) (26.31%) at 6 months, indicating better long-term efficacy in managing refractory glaucoma.

While the AGV initially resulted in lower intraocular pressure (IOP) at 1 week post-surgery, by 6 months, the IOP levels were comparable between both groups, suggesting that AADI may provide sustained control of IOP with fewer required medications.
