Brief Summary:

To evaluate the relative efficacy of three commonly utilized regional corticosteroids for the regional treatment of uveitic macular edema: periocular triamcinolone acetonide; intravitreal triamcinolone acetonide; intravitreal dexamethasone implant. The primary efficacy measure will be percent change in central subfield thickness as measured by OCT at 8 weeks. Participants will continue in the study for 24 weeks in order to evaluate relative effects of the 3 treatment strategies on the duration of treatment effects, requirement for additional injections, and adverse effects.

Note: The planned sample size for the POINT Trial was 267 subjects. On 17 July 2017, with 192 subjects enrolled, the Data and Safety Monitoring Committee (DSMC) reviewed the planned interim analysis and recommended that the goals of the trial could be accomplished by completing follow-up of enrolled subjects without the recruitment of additional subjects. Per the DSMC recommendations, recruitment was suspended and follow-up of enrolled subjects was completed according to the protocol.


Condition or disease Intervention/treatment Phase
Macular Edema Uveitis Drug: Periocular triamcinolone 40 mg Drug: Intravitreal triamcinolone 4 mg Drug: Dexamethasone intravitreal implant Phase 3

Detailed Description:

Macular edema is the most common structural complication and leading cause of visual loss in patients with uveitis. Regional injections of corticosteroids are the most frequently used treatments specifically for uveitic macular edema but there is a lack of high quality evidence to guide choice of drug (e.g., triamcinolone acetonide, dexamethasone) and route of administration (e.g. periocular, intravitreal). The question of how to approach regional treatment of uveitic macular edema is a key question for ophthalmologists treating these patients. The Periocular and Intravitreal Corticosteroids for Uveitic Macular Edema (POINT) Trial is a randomized trial designed to compare the relative efficacy of three regional corticosteroids commonly utilized for the initial regional treatment of uveitic macular edema, periocular triamcinolone (Kenalog® , Bristol-Myers Squibb Company, Princeton, NJ), intravitreal triamcinolone (Triesence™, Alcon Pharmaceuticals, Fort Worth, TX), and the intravitreal dexamethasone implant (Ozurdex®, Allergan, Irvine CA) will be conducted by the MUST Research Group clinical centers throughout the U.S. and one each in Australia and the UK. After signing informed consent and undergoing eligibility evaluation, eligible patients will be randomized to one of the three study treatments to be administered at the first study visit. Randomization is by participant, if both eyes meet eligibility requirements then both eyes receive assigned treatment. The design outcome is the percent change in central subfield macular thickness on OCT from baseline to the 8 week visit. After assessment of the primary outcome at 8 weeks, second injections and best medical judgment will be used if macular edema has not improved as follows:

Eye(s) meeting trial eligibility criteria receive initial injection of assigned treatment at P01 visit.

Second injection of assigned treatment permitted at 8 week visit for periocular triamcinolone and intravitreal triamcinolone and at 12 week visit for intravitreal dexamethasone if

  • Eye does not meet the improvement definition (a 20% decrease in central subfield thickness of the macula) or
  • Eye has a normal central subfield thickness but has cystoid spaces in the 1 mm central subfield or
  • ME is worse after initial improvement

And the following repeat injection criterion are met:

• IOP of ≤21 or mm Hg and treatment with ≤3 IOP-lowering agents;

Eyes demonstrating no improvement or worsening of ME as measured by the central submacular thickness on OCT (at week 12 for periocular and intravitreal triamcinolone arms and at week 20 for intravitreal dexamethasone arm) are considered primary treatment non-responders.

Primary Outcome Measures :
  1. Proportion of Baseline Central Subfield Thickness Observed at 8 Weeks [ Time Frame: At baseline and 8 weeks ]

    The primary outcome is the change in central subfield thickness from baseline to 8 weeks measured on a relative scale as the the proportion of the baseline central subfield thickness. Values less than 1 indicate a decrease in retinal thickness with lower values indicating greater decreases. Smaller values are better.

    The time point of 8 weeks was chosen for assessment of the primary outcome because it encompasses the window for maximum benefit for all three treatment strategies. Retinal thickness was evaluated using masked assessments of OCT images.



Secondary Outcome Measures :
  1. Proportion of Baseline Central Subfield Thickness Observed at 24 Weeks [ Time Frame: At baseline and the 24 week visit ]
    The primary outcome is the change in central subfield thickness from baseline to 24 weeks measured on a relative scale as the the proportion of the baseline central subfield thickness. Values less than 1 indicate a decrease in retinal thickness with lower values indicating greater decreases. Smaller values are better.The time point of 24 weeks was chosen to evaluate the duration of response and the need for additional injections.Retinal thickness was evaluated using masked assessments of OCT images.

  2. Proportion of Eyes With >= 20% Reduction in Macular Thickness (or Normalization Even if <20% Reduction) at 8 Weeks [ Time Frame: Over 8 weeks of follow-up ]
    Proportion of eyes with >=20% reduction in macular thickness (or normalization of macular thickness even if there is <20% reduction) at 8 weeks.

  3. Proportion of Eyes With >= 20% Reduction in Macular Thickness (or Normalization Even if <20% Reduction) at 24 Weeks [ Time Frame: Over 24 weeks of follow-up ]
    Proportion of eyes with >=20% reduction in macular thickness (or normalization of macular thickness even if there is <20% reduction) at 24 weeks

  4. Proportion of Eyes With Resolution of Macular Edema at 8 Weeks [ Time Frame: Over 8 weeks of follow-up ]
    Proportion of eyes with resolution of macular edema defined as normalization of the macular thickness (i.e., < 260 um on the standardized scale) at 8 weeks. The greater the proportion the more eyes achieved resolution of macular edema.

  5. Proportion of Eyes With Resolution of Macular Edema at 24 Weeks [ Time Frame: Over 24 weeks of follow-up ]
    Proportion of eyes with resolution of macular edema defined as normalization of the macular thickness (i.e., <260 um on the standard scale) at 24 weeks.

  6. Change in Best-corrected Visual Acuity at 8 Weeks [ Time Frame: Over 8 weeks of follow-up ]
    Mean change in best-corrected visual acuity from baseline to 8 weeks. Participants' visual acuity was measured by certified examiners with best refractive correction in place.Participants were challenged with reading letters on lines of the standard ETDRS eye chart (5 letters per line). Lines became smaller as participants progressed from the top to the bottom of the chart. Participants read down the chart until no more meaningful readings could be made and were scored by how many letters could be correctly identified. More letters read is associated with higher visual acuity.

  7. Change in Best-corrected Visual Acuity at 24 Weeks [ Time Frame: Over 24 weeks of follow-up ]
    Mean change in best-corrected visual acuity from baseline to 24 weeks. Participants' visual acuity was measured by certified examiners with best refractive correction in place.Participants were challenged with reading letters on lines of the standard ETDRS eye chart (5 letters per line). Lines became smaller as participants progressed from the top to the bottom of the chart. Participants read down the chart until no more meaningful readings could be made and were scored by how many letters could be correctly identified. More letters read is associated with higher visual acuity.

  8. Number of Eyes With Vitreous Hemorrhage [ Time Frame: During 24 weeks of follow-up ]
    Count of eyes with vitreous hemorrhage as an immediate complication of injection.

  9. Number of Eyes With Retinal Tear or Detachment [ Time Frame: During 24 weeks of follow-up ]
    Count of eyes with retinal tears or detachments during the course of follow-up.

  10. Number of Eyes With Endophthalmitis [ Time Frame: During 24 weeks of folllow-ip ]
