ClinConnect Summary

The clinical trial titled "Safety, Tolerability and Efficacy of Intravitreal KIO-104 in Patients with Macular Edema" is designed to investigate a new treatment, KIO-104, for people suffering from macular edema, a condition that causes swelling in the retina and can lead to vision problems. This study will take place at multiple locations and will involve participants who are between 18 and 85 years old. To be eligible, individuals must have a diagnosis of macular edema due to specific causes, such as diabetic retinopathy or previous eye surgery, and must meet certain health criteria.

If you participate in the study, you will receive KIO-104 through an injection into the eye affected by macular edema. The trial will monitor how safe the treatment is, how well it works, and how participants tolerate it. You will need to attend regular study visits and follow specific instructions, including avoiding certain medications during the trial. It's important to note that the study is not yet recruiting participants, so there will be more details available closer to the start date. If you or someone you know is interested in participating, keep an eye out for updates!

Eligibility criteria

• Inclusion Criteria:
• Participants must meet all the following criteria:
• • 1. Be aged 18 to 85 years inclusive at the time of consent.
• • 2. Provide informed consent prior to any study procedures, as stipulated by local laws, Ethics Committee (EC) and Regulatory Authority (RA) guidelines.
• • 3. Be willing and able to follow all study instructions, attend all study visits, and complete all study assessments.
• • 4. Have a clinical diagnosis of ME in the study eye secondary to non-infectious uveitis, retinal vein occlusion, diabetic retinopathy or cataract surgery.
• • 5. If currently receiving systemic corticosteroid therapy or immunosuppressive therapy (or any combination thereof), be on a stable dose of therapy for at least 3 months prior to Screening and during the study.
• • 6. Have a Central Subfield Thickness (CST) of ≥ 350 µm.
• 7. Have a Best Corrected Visual Acuity (BCVA) in the study eye of:
• • 1. ≤ 20/32 (Feet); logMAR ≥ 0.2
• • 2. ≥ 20/800 (Feet); log MAR ≤ 1.6
• • 8. Have media clarity and pupillary dilation sufficient for adequate visualization and assessment of the study eye.
• • 9. Be willing to avoid disallowed medications and treatments for the duration of the study.
• • 10. Agree to follow appropriate contraception requirements from screening until 3 months after the last dose of the study drug.
• • 1. Participants assigned female at birth who are of child-bearing potential (OCBP) must agree to a pregnancy test at Screening and prior to each dose of investigational medicinal product (IMP) and use an acceptable method of birth control including oral, transdermal, injectable, or implantable hormonal contraception, intrauterine device, abstinence from intercourse with partner assigned male at birth, or surgical sterilisation of partner assigned male at birth.
• • 2. Participants assigned female at birth are not OCBP if they have had a hysterectomy, bilateral oophorectomy, bilateral tubal ligation, or are post-menopausal by at least 12 months. Post-menopausal status of amenorrheic female participants should be confirmed at Screening through testing of follicle-stimulating hormone (FSH) as per analysing laboratory threshold.
• • 3. Participants assigned male at birth with a partner OCBP must be surgically sterile for at least 3 months prior to starting study drug, or ensure their partner uses contraception as outlined above, and must use a male condom. Participants assigned male at birth must not donate sperm from Screening until 3 months after the last dose of IMP.
• • 4. Participants who have practiced true abstinence for at least 1 year due to usual and preferred lifestyle choice are exempt from contraceptive requirements. If a participant who is abstinent becomes sexually active, they must agree to use appropriate contraception as described above.
• Exclusion Criteria:
• Participants must not meet any of the following criteria:
• • 1. Have media opacities (cornea, anterior or posterior synechia, cataract, vitreous haze and others) of either eye that preclude investigation and documentation of the posterior pole and intravenous fluorescein angiography, or optical coherence tomography evaluation in the study eye.
• • 2. Receive local or systemic biologicals (i.e. tumour necrosis factor \[TNF\]-blockers, B-cell blockers, cytokines, cytokine-blockers, receptor antagonists) 90 days prior to Day 1 or planned during the study.
• • 3. Receive treatment with cyclophosphamide or chlorambucil during the study.
• • 4. Receive intravitreal injections (including but not limited to anti-vascular endothelial growth factors) 90 days prior to Day 1 or planned during the study.
• • 5. Receive a posterior subtenon's or orbital floor injection of steroids 90 days prior to Day 1 or planned during the study.
• 6. Have any implantable corticosteroid-eluting device (Ozurdex, Iluvien, Retisert, triamcinolone intravitreal implant, fluocinolone intravitreal implant) in the study eye, with the following exceptions:
• • 1. If the device had been removed more than 90 days prior to Day 1 of the study.
• • 2. If Ozurdex® had been implanted at least 6 months before Day 1 of the study.
• • 3. If Iluvien® or Retisert® had been implanted at least 3 years before Day 1 of the study.
• • 4. Use of topical steroids are permissible provided the participant is receiving a stable dose for at least 3 months prior to Screening and during the study.
• • 7. Have ocular surgery (including cataract extraction, vitreoretinal or scleral buckling surgery) in the study eye, within 90 days prior to Day 1, or planned during the study.
• • 8. Have a capsulotomy in the study eye, within 30 days prior to Day 1, and during the study.
• • 9. Have Intraocular pressure (IOP) ≥ 25 mmHg in the study eye (glaucoma patients maintained on no more than one topical medication with IOP \< 25 mmHg are allowed to participate).
• • 10. Have ocular hypotony (IOP \< 6 mmHg).
• • 11. Have aphakia or anterior chamber lens in the study eye.
• • 12. Have visible scleral thinning, scleral ectasia or keratoconus in the study eye.
• • 13. Have presence of any ocular malignancy in either eye.
• • 14. Have evidence of any other clinically significant ocular disease that might interfere with the study assessments.
• • 15. Have ocular or periocular (either eye) or systemic infection and/or a temperature greater than 38.0°C, or the use of systemic or topical ocular antibiotics within 14 days of Day 1.
• • 16. Have a psychiatric condition that, in the investigator's opinion, precludes compliance with the protocol; past or present psychoses; past or present bipolar disorder; disorder requiring lithium; or within five years prior to screening, a history of suicide plan.
• • 17. Have any clinically significant abnormality at screening determined by medical and ophthalmic history, vital signs, clinical biochemistry, hematology, urinalysis, or a 12-lead electrocardiogram (ECG), as assessed by the investigator, which might interfere with the study assessments or the ability of the participant to complete the study.
• • 18. Have any other medical condition or significant co-morbidities, or any finding during screening, which in the view of the investigator is likely to interfere with the study or put the participant at risk, confound study data, or interfere significantly with study participation.
• • 19. Have participated in any other investigational drug or device clinical trial within 90 days prior to Day 1 or planning to participate in other investigational drug or device clinical trials during the study and within 90 days following Day 1.
