A plain-language read of the study's public EU CTIS listing. The study team confirms the details.

Who can take part

You may be able to join if

  • Signed informed consent form before any study-specific procedures are performed.
  • Male or female adult subject aged 18 to 85 years.
  • DME with presence of intraretinal and/or subretinal fluid in the study eye, with CST of ≥310 µm by SD-OCT at screening (Visit 1) (to be confirmed by CRC); CST is not part of the eligibility reconfirmation on Day 1 (Visit 2).
  • BCVA ETDRS letters score >35 letters (>20/200 Snellen equivalent) in the non-study eye at screening (ie, as per definition of monocular blindness).
  • BCVA ETDRS letters score ≤65 (Snellen 20/50) and ≥24 (Snellen 20/320) in the study eye at screening and baseline (Visit 1 and Visit 2).
  • Documented diagnosis of Type 1 or Type 2 diabetes mellitus and an HbA1c of ≤ 10.0% prior to screening (Visit 1) (historic values of HbA1c taken up to 2 months before the screening visit will be permissible otherwise the study site will collect a sample for analysis at screening [Visit 1]).

You likely can't join if

  • Macular edema considered to be because of a cause other than DME. Examples included: The macular edema is considered to be related to ocular surgery, clinical exam and/or OCT suggest that vitreoretinal interface abnormalities disease, acute macular degeneration (AMD), retinal vein occlusion (RVO), uveitis.
  • Currently enrolled in or have participated in any other clinical study involving a study drug or device, or in any other type of medical research, within 30 days before screening and up to completion of the current study.
  • Use of systemic corticosteroids (ie, oral, IM, IV, intranasal) within 1 month prior to Day 1 and no systemic corticosteroids anticipated throughout the study.
  • Any prior or concomitant systemic anti-VEGF treatment within 6 months prior to Day 1.
  • Any other medical condition that in the opinion of the investigator may affect BCVA, may put the subject at significant risk, may confound the study results, or may interfere significantly with the subject’s participation in the study.
  • Decrease in BCVA because of causes other than DME.

  • Negative urine pregnancy test at Visit 1, if women of childbearing potential (WOCBP) those who have experienced menarche and who are not surgically sterilized ([bilateral tubal ligation, hysterectomy or bilateral oophorectomy] or postmenopausal [12 months after last menses]) and must use adequate birth control throughout the study period (refer to Appendix 2 of the protocol).
What rules you out

  • Decrease in BCVA because of causes other than DME.
  • Known history of significant macular ischemia which would prevent gain in visual acuity in the study eye.
  • Any other ocular disease in the study eye that may cause substantial reduction in BCVA, including retinal detachment, vitreomacular traction, epiretinal membrane, vitreous hemorrhage or fibrosis involving the macula, ocular inflammation (uveitis), other retinal inflammatory or infectious diseases.
  • Active or suspected periocular or ocular infection in the study eye. Mild noninfectious blepharitis is accepted.
