PDS Implant with Ranibizumab for Age-Related Macular Degeneration
(Portal Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new method to treat neovascular age-related macular degeneration (nAMD), a condition affecting vision. It uses a Port Delivery System (PDS) to deliver ranibizumab (also known as Lucentis or Susvimo), a medication designed to improve eye health and vision over the long term. Those previously involved in specific studies about nAMD and treated with anti-VEGF injections (medications that reduce blood vessel growth in the eye) might find this trial suitable. Participants will undergo various procedures with the PDS to evaluate its effectiveness and safety. As a Phase 3 trial, this treatment represents the final step before FDA approval, offering a chance to contribute to advancing eye care.
Will I have to stop taking my current medications?
The trial requires that participants do not use certain medications, as there is a 'Prohibited Therapy' list. If you are on any continuous medications, you may need to stop them if they are on this list. Please consult with the trial coordinators for specific details.
What prior data suggests that the PDS implant with ranibizumab is safe for age-related macular degeneration?
Research has shown that the Port Delivery System (PDS) with ranibizumab is generally safe and well-tolerated for individuals with neovascular age-related macular degeneration (nAMD). This system continuously delivers the drug, helping to maintain vision over several years. Consequently, patients require fewer eye injections, which many find more convenient.
Early results from ongoing studies suggest that after four years, the PDS remains effective and has similar safety outcomes compared to traditional monthly injections. The PDS with ranibizumab has already received approval in the United States for treating nAMD, supporting its safety for this condition.
As with any treatment, side effects can occur. However, current data from these studies provide a positive view of the treatment’s safety. Discussing potential risks and benefits with a healthcare provider is important for making informed decisions about joining a clinical trial.12345Why do researchers think this study treatment might be promising for age-related macular degeneration?
Researchers are excited about the PDS (Port Delivery System) implant with ranibizumab for age-related macular degeneration (AMD) because it offers a new way to deliver medication. Unlike traditional treatments that require frequent eye injections, this implant continuously delivers ranibizumab directly to the eye, potentially reducing the need for repeated injections. This innovative delivery method could provide more consistent treatment and improve patient comfort and convenience. Additionally, the implant's ability to maintain drug levels over extended periods could enhance the effectiveness of AMD management.
What evidence suggests that the PDS implant with ranibizumab could be effective for age-related macular degeneration?
Research has shown that the Port Delivery System (PDS) with ranibizumab effectively treats wet age-related macular degeneration (nAMD). This trial includes various treatment arms, such as Sub-study 1 and Sub-study 2, where participants receive the PDS implant with ranibizumab. Studies indicate that this system can maintain vision for up to five years with only two refills a year. This treatment provides a continuous supply of medicine, which many people prefer over monthly injections. Early trial results suggested it keeps vision stable and offers reliable, long-term benefits. The PDS is specifically designed to help manage vision loss in those with wet age-related macular degeneration.14678

Experimental Treatment
Participants who received an updated PDS implant, have \< 48 weeks post-re-implantation follow-up and one refill exchange visit in the main study, will undergo one refill-exchange procedure with ranibizumab 100 mg/mL Q24W post main study re-implantation visit.
Participants who received an updated PDS implant, have \< 24 weeks post-re-implantation follow-up and no refill exchange visit in the main study, will undergo two refill-exchange procedures with ranibizumab 100 mg/mL Q24W post main study re-implantation visit.
Participants will undergo re-implantation with the updated PDS implant and receive 2 refill-exchanges of ranibizumab 100 mg/mL Q24W.
Participants will receive PDS implant using TPC on Day 1 followed by refill-exchanges of ranibizumab 100 mg/mL via the PDS Q24W.
Participants from Study WR42221 randomized to the Q36W arm, who will continue to be treated with refill-exchanges of ranibizumab 100 mg/mL Q36W. Participants will be in the study for a minimum of 144 weeks and may continue after Week 144 until the PDS has received Health Authority approval (or non-approval) in their respective country and/or until the decision to close the study has been made by the sponsor.
