Brief Summary:

The purpose of this study during the Dose Escalation stage is to assess the safety and tolerability of 3 ascending doses of ASP7317 in participants with age-related macular degeneration (AMD), of which one dose will be selected for evaluation of efficacy and safety during the Proof of Concept (PoC) stage of the study.

The primary purpose of the study during the PoC stage is to assess the safety, tolerability and superiority of ASP7317 at low cells/dose and the selected dose compared to untreated control and ASP7317 low cells/dose versus the selected dose in best corrected visual acuity (BCVA). This study will also assess safety by incidence of graft failure or rejection with a 13-week regimen of immunosuppression therapy.

Efficacy will also be assessed by the differences among ASP7317 at low cells/dose, ASP7317 at the selected dose and the untreated control group in other functional and structural parameters and patient reported outcomes during the PoC stage.

During the Extension stage this study will assess the safety and tolerability of ASP7317 at the most efficacious dose from PoC in participants randomized to the untreated control group.


Condition or disease Intervention/treatment Phase
Age-Related Macular Degeneration Drug: ASP7317 Other: Placebo Drug: tacrolimus Drug: mycophenolate mofetil (MMF) Phase 1 Phase 2

Detailed Description:

This is a two stage study followed by an extension stage. Stage 1 is a Phase 1b dose escalation evaluation of 3 doses of ASP7317; Stage 2 is Phase 2 Proof of Concept (PoC) investigation and Stage 3 is the extension stage which offers treatment options for participants randomized to the untreated control group in Stage 2.

During the dose escalation stage participants will be treated in each of the 3 dose cohorts (low cells/dose; medium cells/dose; high cells/dose). Doses will be administered to the study eye via a subretinal injection. Four weeks after the last participant in each dose cohort is treated, the independent Data Safety Monitoring Board (DSMB) will review data and images. Depending on the safety data there will be a recommendation to continue enrollment in the current cohort, or open enrollment for the next higher dose; stop dose escalation; investigate a lower dose or repeat a dose level.

The PoC stage will begin immediately following the decision of the Dose Escalation Committee (DEC) on the selected dose. Participants will be randomized in a 1:1:1 ratio to either the low cells/dose; the selected cells/dose or an untreated control group. Doses will be administered to the study eye via a subretinal injection for the low cells/dose and the selected cells/dose.

All participants treated with ASP7317 in the Dose Escalation and PoC stage will receive 13 weeks of immunosuppressive therapy (IMT) starting 1 week prior to day of transplant and continuing for 12 weeks post-transplant. If the primary outcome for PoC is demonstrated for the low cells/dose and the selected cells/dose then participants in the untreated control group who completed the 26 week visit are allowed to cross over to treatment with ASP7317 provided the participants remain suitable for immunosuppression therapy and ASP7317.

At the last study visit or time of withdrawal participants receiving ASP7317 will be consented to participate in the safety surveillance period of the study (under a separate protocol 7316-CL-0007), which will continue to monitor the participants for long-term safety via an annual questionnaire.

Arm Intervention/treatment
Experimental: ASP7317 Dose Escalation
Successive cohorts of participants (3 participants/ 3 cohort) will be treated in each escalating dose cohort (low cells/dose; medium cells/dose; high cells/dose). All participants in the low cells/dose and medium cells/dose cohorts may be treated simultaneously. The high cells/dose cohort will require sentinel dosing. After the first participant is dosed with high cells/dose and followed for 6 weeks the independent Data Safety Monitoring Board (DSMB) will review the safety data and images and recommend if the second and third participants may be treated with high cells/dose. One of the 3 doses will be selected for evaluation of efficacy and safety during the Proof of Concept (PoC) stage of the study. All participants will receive 13 weeks of immunosuppressive therapy (IMT) starting 1 week prior to day of transplant and continuing for 12 weeks posttransplant.
