NCT05151744

Brief Summary

Study BP43464 is a phase II, multicenter, randomized, double-masked active comparator-controlled study designed to assess the efficacy, safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of vamikibart in combination with, anti-vascular endothelial growth factor (VEGF) inhibitor, ranibizumab compared with ranibizumab alone in participants with diabetic macular edema. Only one eye will be chosen as the study eye. The duration of the study will be 76 weeks.

Outcome Measures

Primary Outcomes (1)

  • Change From Baseline in Best Corrected Visual Acuity (BCVA) Averaged Over Week 44 and Week 48 in Treatment-naïve Participants

    BCVA was measured via Early Treatment Diabetic Retinopathy Study (ETDRS) chart at a starting distance of 4 meters using a set of three Precision vision\^TM or Lighthouse distance acuity charts (modified ETDRS Charts 1, 2, and R) prior to dilating eyes by a trained and certified visual acuity (VA) examiner. The BCVA letter score ranges from 0 to 100 letters. Higher scores and gain in BCVA from baseline indicate improvement in VA. This analysis used a Mixed Model for Repeated Measurements (MMRM) model.

    Baseline, Week 44 and Week 48

Secondary Outcomes (28)

  • Number of Participants With Systemic and Ocular Adverse Events (AEs)

    Up to Week 72

  • Change From Baseline in BCVA Averaged Over Week 44 and Week 48 in Previously Treated Participants

    Baseline, Week 44 and Week 48

  • Change From Baseline in BCVA Averaged Over Week 44 and Week 48 in Overall ITT Population

    Baseline, Week 44 and Week 48

  • Change From Baseline in BCVA Averaged Over Week 32 and Week 36, in Treatment-naïve Participants

    Baseline, Week 32 and Week 36

  • Change From Baseline in BCVA Averaged Over Week 32 and Week 36, in Previously Treated Participants

    Baseline, Week 32 and Week 36

  • +23 more secondary outcomes

Study Arms (2)

Arm A: Vamikibart + Ranibizumab

EXPERIMENTAL

Participants will receive vamikibart, 1 milligram (mg) administered as intravitreal (IVT) injection in combination with ranibizumab, 0.5 mg IVT, on Day 1 and every fourth week (Q4W) up to Week 44, for a total of 12 injections, followed by an observational period up to Week 72.

Drug: VamikibartDrug: Ranibizumab

Arm B: Ranibizumab

ACTIVE COMPARATOR

Participants will receive ranibizumab, 0.5 mg IVT, from Day 1 and Q4W in combination with sham up to Week 44, for a total of 12 injections, followed by an observational period up to Week 72.

Drug: RanibizumabOther: Sham Procedure

Interventions

Vamikibart will be administered by IVT injection in the study eye.

Also known as: RO7200220
Arm A: Vamikibart + Ranibizumab

Ranibizumab will be administered by IVT injection in the study eye.

Also known as: Lucentis
Arm A: Vamikibart + RanibizumabArm B: Ranibizumab

Sham is a procedure that mimics an IVT injection and involves the blunt end of an empty syringe (without a needle) being pressed against the anesthetized eye.

Arm B: Ranibizumab

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Diagnosis of diabetes mellitus (Type 1 or Type 2)
  • Macular thickening secondary to diabetic macular edema (DME) involving the center of the macula
  • Decreased visual acuity attributable primarily to DME
  • Ability and willingness to provide written informed consent and to comply with the study protocol
  • Willingness to allow Aqueous Humor collection
  • For women of childbearing potential: agreement to remain abstinent or use at least one highly effective contraceptive method that results in a failure rate of \<1% per year during the treatment period and for at least 12 weeks after the final dose of study treatment

You may not qualify if:

  • Hemoglobin A1c (HbA1c) of greater than (\>) 12%
  • Uncontrolled blood pressure, defined as a systolic value greater than (\>)180 millimeters of mercury (mmHg) and/or a diastolic value \>100 mmHg while a patient is at rest
  • Currently pregnant or breastfeeding, or intend to become pregnant during the study
  • Prior treatment with panretinal photocoagulation or macular laser to the study eye
  • Any intraocular or periocular corticosteroid treatment within the past 16 weeks prior to Day 1 to the study eye
  • Prior Iluvien or Retisert implants within 3 years prior to Day 1 to the study eye
  • Prior or concomitant treatment with anti-VEGF therapy within 8 weeks prior to Day 1 to the study eye; Vabysmo\^TM within 16 weeks prior to Day 1, prior Beovu® is not permitted
  • Prior administration of IVT brolucizumab (Beovu®): ever; vamikibart: \</=24 weeks prior to Day 1) in either eye
  • Any proliferative diabetic retinopathy
  • Active intraocular or periocular infection or active intraocular inflammation in the study eye
  • Any current or history of ocular disease other than DME that may confound assessment of the macula or affect central vision in the study eye
  • Any current ocular condition which, in the opinion of the investigator, is currently causing or could be expected to contribute to irreversible vision loss due to a cause other than DME in the study eye
