A Study to Evaluate the Safety, Tolerability and Pharmacokinetics of IVT MHU650 in Macular Edema Patients

Phase 1

Completed

Conditions: Macular Edema
Neovascular Age-related Macular Degeneration
Diabetic Macular Edema
Retinal Vein Occlusion

Brief Summary: This was an open-label, multi-center, FIH study with a single ascending dose (SAD) design that assessed the safety, tolerability and pharmacokinetics (PK) of a single IVT dose of MHU650 in up to 24 participants with macular edema.

Detailed Description: A total of up to 4 cohorts were planned to be enrolled, with an additional lower or intermediate cohort of participants. First to third generation Japanese participants could be enrolled in all cohorts but were not required to be enrolled. The screening period for this study will be up to 60 days. A single dose of MHU650 intravitreal injection will be administered at Baseline / Day 1 in the study eye. The follow up period will last until Day 60 / end of study (EOS). A post study safety phone contact call will occur 30 days after the EOS visit.

Recruitment & Eligibility

Inclusion Criteria

Patients with macular edema in at least one eye, including those with focal or diffuse diabetic macular edema (DME), neovascular age-related macular degeneration (nAMD), or retinal vein occlusion (RVO). In the opinion of the investigator, the decrease in vision in the study eye must be due to macular edema.
Early Treatment Diabetic Retinopathy (ETDRS) letter score in the study eye must equal to or worse than 60 letters (approximately Snellen equivalent of 20/63) but better than 14 letters (20/500) at screening and baseline. The ETDRS score in the non-study eye should be ≥ 60 letters at screening and baseline.
Sufficiently clear ocular media and adequate pupil dilation to permit fundus photographs of adequate clarity to measure diameters of retinal arteries and veins
Vital signs as specified in the protocol

Key

Exclusion Criteria

Concomitant conditions or ocular disorders in the study eye which may, in the opinion of the investigator, confound the interpretation of study results, compromise visual acuity or require medical or surgical intervention during the study period
High risk and/or/ active proliferative diabetic retinopathy in the study eye, as per investigator assessment at both screening and baseline.
Participants with the following conditions in the study eye at screening or baseline must be excluded: structural damage of the fovea, vitreous hemorrhage, retinal detachment, vitreomacular traction, macular hole, retinal arterial occlusion, neovascularization of iris of any cause.
Laser photocoagulation (macular or panretinal) in the study eye during the 6-month period prior to baseline.
Patients with type 1or type 2 diabetes who have hemoglobin A1C of ≥ 12 at screening
Other ocular conditions as specified in the protocol
Systemic conditions as specified in the protocol

Primary Outcome Measures

Name	Time	Method
Number of participants with ocular and nonocular adverse events	Day 1 to Day 60	An adverse event (AE) is any untoward medical occurrence (e.g. any unfavorable and unintended sign \[including abnormal laboratory findings\], symptom or disease) in a clinical investigation participant after providing written informed consent for participation in the study.
Change from baseline in Best Correct Visual Acuity (BCVA ) by dose level and timepoint - Study Eye	Day 1 to Day 60	Best Correct Visual Acuity was assessed using Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity testing charts.
Change from baseline in Central subfield thickness (CSFT) (µm) in the study eye by dose level and timepoint	Day 1 to Day 60	Central subfield thickness was measured by spectral domain optical coherence tomography (SD-OCT).
Change from baseline in Intraocular pressure (IOP) (mmHg) in the study eye by dose level and timepoint	Day 1 to Day 60	Intraocular pressure was measured per the sites' local standard operating procedures, via tonometry.
