Safety and Efficacy of Faricimab in Patients With NPDR

The purpose of this Phase 2 study is comprised of two groups to evaluate the safety, tolerability, and efficacy of faricimab in patients with Non-Proliferative Diabetic Retinopathy.

Group 1: Subjects will be administered intravitreal faricimab every 4 through week 48 and then will be receive faricimab every 16 weeks with an end of study visit at week 96. At any visit after Week 48, if rescue criteria are met, faricimab 6mg will be given every 4 weeks and the subject will continue dosing through the end of the trial.

Group 2: Subjects are seen and observed every 16 weeks. Starting at Week 48, subjects will be administered intravitreal faricimab every 4 weeks from week 48 to week 92 with an end of study visit at week 96. At any visit before Week 48, if rescue criteria are met, faricimab will be given every 4 weeks and the subject will continue dosing through the end of the trial.

Eligibility Criteria:
Inclusion Criteria:

* Provide signed IRB-approved informed consent form (ICF) prior to any study-specific procedures
* Willing and able to comply with clinic visits and study-related procedures and likely to return for all study visits, in the investigator's judgement
* Men or women \&gt; 18 years of age at the time of signing the Informed Consent Form
* Diagnosis of diabetes mellitus (type 1 or type 2)
* For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use acceptable contraceptive methods that result in a failure rate of \&lt; 1% per year during the treatment period and for at least 3 months after the final dose of study treatment. A woman is considered to be of childbearing potential if she is post-menarcheal, has not reached a post-menopausal state (\&gt;12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus). The definition of childbearing potential may be adapted for alignment with local guidelines or requirements. Examples of acceptable contraceptive methods include bilateral tubal ligation, male sterilization, hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices, and copper intrauterine devices.

Contraception methods that do not result in a failure rate of \&lt; 1% per year such as male or female condom with or without spermicide; and cap, diaphragm, or sponge with spermicide are not acceptable.

The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the subject. If a subject is usually not sexually active but becomes active, they, with their partner, must comply with the contraceptive requirements of the study.

Ocular inclusion criteria for study eye:

Subjects must meet the following ocular inclusion criteria for the study eye for entry into the study:

* ETDRS BCVA \&gt; 20/400 in the study eye
* Non-proliferative diabetic retinopathy, as confirmed by the site investigator
* Substantial non-perfusion (defined as greater than 5 disc areas on Wide-Field Fluorescein Angiograph (WFFA)), as assessed by site investigator

Exclusion Criteria:

* Any known hypersensitivity to any of the components in the faricimab injection
* Any known hypersensitivity to any contrast media (e.g., fluorescein), dilating eye drops, disinfectants (e.g., iodine), or any of the anesthetics and antimicrobial preparations used by the site during the study
* Active cancer within the past 12 months prior to Screen/Baseline except for appropriately treated carcinoma in situ of the cervix, non-melanoma skin carcinoma, and prostate cancer with a Gleason score of ≤6 and a stable prostate-specific antigen for \&gt;12 months
* Stroke (cerebral vascular accident) or myocardial infarction within 6 months prior to Screen/Baseline
* Pregnant or breastfeeding, or intending to become pregnant during the study or within 3 months after the final dose of faricimab

  o Women of childbearing potential must have a negative urine pregnancy test at the Screen/Baseline visit for both Group 1 and Group 2. Women of childbearing potential must also have a negative urine pregnancy test on any visit where they will receive treatment with IP or rescue medication. Urine pregnancy tests must be completed prior to the administration of IP/rescue medication and prior to FA being performed.
* Participation in an investigational trial that involves treatment with any drug or device (with the exception of vitamins or minerals) within 3 months (or 5 half-lives, whichever is longer) prior to Screen/Baseline, or during the course of this study
* Any prior or concomitant systemic anti-VEGF treatment within 4 months prior to Screen/Baseline
* Any use of any prohibited therapies during times of prohibition.

Ocular exclusion criteria for study eye:

Subjects who meet any of the following exclusion criteria for the study eye will be excluded from study entry:

* Any history of treatment with anti-VEGF or any periocular or IVT corticosteroids in the study eye within 4 months prior to Screen/Baseline
* SD-OCT central subfield thickness (CST) measurement \&gt; 325 µm, in the study eye due to DME.
* Evidence of infectious ocular infection, in the study eye at Screen/Baseline
* Any pan-retinal photocoagulation (PRP) treatment received in the study eye prior to Screen/Baseline
* Retinal vein occlusion in the study eye
* Cystoid macular edema not attributed to diabetes (instead caused by epiretinal membrane, macular telangiectasia, Coats disease, and inherited retinal diseases) in the study eye
* Current vitreous hemorrhage obscuring imaging in the study and/or dilated indirect examination
* Any intraocular surgery (e.g., cataract surgery) within 4 weeks prior to Screen/Baseline in the study eye
* Active intraocular inflammation including scleritis at screening/baseline
