Generic Name: ocriplasmin
Dosage Form: injection, solution


Jetrea® is a proteolytic enzyme indicated for the treatment of symptomatic vitreomacular adhesion.


. General Dosing Information

Must be diluted before use. For single-use ophthalmic intravitreal injection only. Jetrea must only be administered by a qualified physician.

. Dosing

The recommended dose is 0.125 mg (0.1 mL of the diluted solution) administered by intravitreal injection to the affected eye once as a single dose.

. Preparation for Administration

To prepare Jetrea for intravitreal injection, adhere to the following instructions:

  1. Remove the vial (2.5 mg/mL corresponding to 0.5 mg ocriplasmin) from the freezer and allow to thaw at room temperature (within a few minutes).

  2. Once completely thawed, remove the protective polypropylene flip-off cap from the vial (see Figure 1).

    Figure 1:

  3. The top of the vial should be disinfected with an alcohol wipe (see Figure 2).

  4. Using aseptic technique, add 0.2 mL of 0.9% w/v Sodium Chloride Injection, USP (sterile, preservative-free) into the Jetrea vial (see Figure 3) and gently swirl the vial until the solutions are mixed (see Figure 4).

    Figure 3:

    Figure 4:

  5. Visually inspect the vial for particulate matter. Only a clear, colorless solution without visible particles should be used.

  6. Using aseptic technique, withdraw all of the diluted solution using a sterile #19 gauge needle (slightly tilt the vial to ease withdrawal) and discard the needle after withdrawal of the vial contents (see Figure 5). Do not use this needle for the intravitreal injection.

    Figure 5:

  7. Replace the needle with a sterile #30 gauge needle, carefully expel the air bubbles and excess drug from the syringe and adjust the dose to the 0.1 mL mark on the syringe (corresponding to 0.125 mg ocriplasmin) (see Figure 6).

  9. Discard the vial and any unused portion of the diluted solution after single use.

. Administration and Monitoring

The intravitreal injection procedure should be carried out under controlled aseptic conditions, which include the use of sterile gloves, a sterile drape and a sterile eyelid speculum (or equivalent). Adequate anesthesia and a broad spectrum microbiocide should be administered according to standard medical practice.

The injection needle should be inserted 3.5 - 4.0 mm posterior to the limbus aiming towards the center of the vitreous cavity, avoiding the horizontal meridian. The injection volume of 0.1 mL is then delivered into the mid-vitreous.

Immediately following the intravitreal injection, patients should be monitored for elevation in intraocular pressure. Appropriate monitoring may consist of a check for perfusion of the optic nerve head or tonometry. If required, a sterile paracentesis needle should be available.

Following intravitreal injection, patients should be instructed to report any symptoms suggestive of endophthalmitis or retinal detachment (e.g., eye pain, redness of the eye, photophobia, blurred or decreased vision) without delay [see Patient Counseling Information (17)].

Each vial should only be used to provide a single injection for the treatment of a single eye. If the contralateral eye requires treatment, a new vial should be used and the sterile field, syringe, gloves, drapes, eyelid speculum, and injection needles should be changed before Jetrea is administered to the other eye, however, treatment with Jetrea in the other eye is not recommended within 7 days of the initial injection in order to monitor the post-injection course including the potential for decreased vision in the injected eye.

Repeated administration of Jetrea in the same eye is not recommended [see Nonclinical Toxicology (13.2)].

After injection, any unused product must be discarded.

No special dosage modification is required for any of the populations that have been studied (e.g. gender, elderly).

. Decreased Vision

A decrease of ≥ 3 line of best corrected visual acuity (BCVA) was experienced by 5.6% of patients treated with Jetrea and 3.2% of patients treated with vehicle in the controlled trials [see Clinical Studies (14)].

The majority of these decreases in vision were due to progression of the condition with traction and many required surgical intervention. Patients should be monitored appropriately [see Dosage and Administration (2.4)].

. Intravitreal Injection Procedure Associated Effects

Intravitreal injections are associated with intraocular inflammation / infection, intraocular hemorrhage and increased intraocular pressure (IOP). In the controlled trials, intraocular inflammation occurred in 7.1% of patients injected with Jetrea vs. 3.7% of patients injected with vehicle. Most of the post-injection intraocular inflammation events were mild and transient. Intraocular hemorrhage occurred in 2.4% vs. 3.7% of patients injected with Jetrea vs. vehicle, respectively. Increased intraocular pressure occurred in 4.1% vs. 5.3% of patients injected with Jetrea vs. vehicle, respectively.

. Potential for Lens Subluxation

One case of lens subluxation was reported in a premature infant who received an intravitreal injection of 0.175 mg (1.4 times higher than the recommended dose) [see Pediatric Use (8.4)]. Lens subluxation was observed in three animal species (monkey, rabbit, minipig) following a single intravitreal injection that achieved vitreous concentrations of ocriplasmin 1.4 times higher than achieved with the recommended treatment dose. Administration of a second intravitreal dose in monkeys, 28 days apart, produced lens subluxation in 100% of the treated eyes [see Nonclinical Toxicology (13.2)].

. Retinal Breaks

In the controlled trials, the incidence of retinal detachment was 0.9% in the Jetrea group and 1.6% in the vehicle group, while the incidence of retinal tear (without detachment) was 1.1% in the Jetrea group and 2.7% in the vehicle group. Most of these events occurred during or after vitrectomy in both groups. The incidence of retinal detachment that occurred pre-vitrectomy was 0.4% in the Jetrea group and none in the vehicle group, while the incidence of retinal tear (without detachment) that occurred pre-vitrectomy was none in the Jetrea group and 0.5% in the vehicle group.

. Dyschromatopsia

Dyschromatopsia (generally described as yellowish vision) was reported in 2% of all patients injected with Jetrea. In approximately half of these dyschromatopsia cases there were also electroretinographic (ERG) changes reported (a- and b-wave amplitude decrease).


The following adverse reactions are described below and elsewhere in the labeling:

  •   Decreased Vision [see Warnings and Precautions (5.1)]
  •   Intravitreal Injection Procedure Associated Effects [see Warnings and Precautions (5.2) and Dosage and Administration (2.4)]
  •   Potential for Lens Subluxation [see Warnings and Precautions (5.3)]
  •   Retinal Breaks [see Warnings and Precautions (5.4) and Dosage and Administration (2.4)]

. Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates in one clinical trial of a drug cannot be directly compared with rates in the clinical trials of the same or another drug and may not reflect the rates observed in practice.

Approximately 800 patients have been treated with an intravitreal injection of Jetrea. Of these, 465 patients received an intravitreal injection of ocriplasmin 0.125 mg (187 patients received vehicle) in the 2 vehicle-controlled studies (Study 1 and Study 2).

The most common adverse reactions (incidence 5% - 20% listed in descending order of frequency) in the vehicle-controlled clinical studies were: vitreous floaters, conjunctival hemorrhage, eye pain, photopsia, blurred vision, macular hole, reduced visual acuity, visual impairment, and retinal edema.

Less common adverse reactions observed in the studies at a frequency of 2% - < 5% in patients treated with Jetrea included macular edema, increased intraocular pressure, anterior chamber cell, photophobia, vitreous detachment, ocular discomfort, iritis, cataract, dry eye, metamorphopsia, conjunctival hyperemia, and retinal degeneration.

Dyschromatopsia was reported in 2% of patients injected with Jetrea, with the majority of cases reported from two uncontrolled clinical studies. In approximately half of these dyschromatopsia cases there were also electroretinographic (ERG) changes reported (a- and b-wave amplitude decrease).

. Immunogenicity

As with all therapeutic proteins, there is potential for immunogenicity. Immunogenicity for this product has not been evaluated.

. Postmarketing Experience

The following adverse reactions have been identified during post-approval use of Jetrea. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

  • Cystoid macular edema
  • Night blindness
  • Pupillary reflex impaired
  • Visual symptoms perceived in the contralateral eye or bilaterally


.  Pregnancy

Teratogenic Effects

Pregnancy Category C. Animal reproduction studies have not been conducted with ocriplasmin. There are no adequate and well-controlled studies of ocriplasmin in pregnant women. It is not known whether ocriplasmin can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. The systemic exposure to ocriplasmin is expected to be low after intravitreal injection of a single 0.125 mg dose. Assuming 100% systemic absorption (and a plasma volume of 2700 mL), the estimated plasma concentration is 46 ng/mL. Jetrea should be given to a pregnant woman only if clearly needed.

. Nursing Mothers

It is not known whether ocriplasmin is excreted in human milk. Because many drugs are excreted in human milk, and because the potential for absorption and harm to infant growth and development exists, caution should be exercised when Jetrea is administered to a nursing woman.

.  Pediatric Use

The use of Jetrea in pediatric patients is not recommended. A single center, randomized, placebo controlled, double masked clinical study to investigate the safety and efficacy of a single intravitreal injection of 0.175 mg ocriplasmin in pediatric subjects as an adjunct to vitrectomy was conducted in 24 eyes of 22 patients. There were no statistical or clinical differences between groups for the induction of total macular PVD, any of the secondary endpoints or adverse events.

.  Geriatric Use

In the clinical studies, 384 and 145 patients were ≥ 65 years and of these 192 and 73 patients were ≥ 75 years in the Jetrea and vehicle groups respectively. No significant differences in efficacy or safety were seen with increasing age in these studies.


The clinical data on the effects of Jetrea overdose are limited. One case of accidental overdose of 0.250 mg ocriplasmin (twice the recommended dose) was reported to be associated with inflammation and a decrease in visual acuity.


Ocriplasmin is a recombinant truncated form of human plasmin with a molecular weight of 27.2 kDa produced by recombinant DNA technology in a Pichia pastoris expression system.

Jetrea is a sterile, clear and colorless solution with no preservatives in a single-use glass vial containing 0.5 mg ocriplasmin in 0.2 mL solution for intravitreal injection after dilution.

Each vial contains 0.5 mg ocriplasmin (active) and 0.21 mg citric acid, 0.75 mg mannitol, sodium hydroxide (for pH adjustment) and water for injection. The pH of the solution is 3.1.


.  Mechanism of Action

Ocriplasmin has proteolytic activity against protein components of the vitreous body and the vitreoretinal interface (VRI) (e.g. laminin, fibronectin and collagen), thereby dissolving the protein matrix responsible for the vitreomacular adhesion (VMA).

.  Pharmacokinetics

The intravitreal pharmacokinetics of ocriplasmin were determined in a clinical study in patients scheduled for vitrectomy where 0.125 mg ocriplasmin (corresponding to an average concentration of 29 mcg ocriplasmin per mL vitreous volume [approximately 4.3 mL/eye]) was administered as a single intravitreal dose at different time points prior to vitrectomy. The mean ocriplasmin activity levels decreased with time from injection to time of sampling as illustrated in Table 1, according to a second order kinetic process. At 24 hours post injection the levels in the vitreous were below 3% of the theoretical concentration reached immediately after injection.

Because of the small dose administered (0.125 mg), detectable levels of ocriplasmin in systemic circulation are not expected after intravitreal injection.

Ocriplasmin enters the endogenous protein catabolism pathway through which it is rapidly inactivated via its interactions with protease inhibitor α2-antiplasmin or α2-macroglobulin.


.  Carcinogenesis, Mutagenesis, Impairment of Fertility

No carcinogenicity, mutagenicity or reproductive and developmental toxicity studies were conducted with ocriplasmin.

.  Animal Toxicology and/or Pharmacology

The ocular toxicity of ocriplasmin after a single intravitreal dose has been evaluated in rabbits, monkeys and minipigs. Ocriplasmin induced an inflammatory response and transient ERG changes in rabbits and monkeys, which tended to resolve over time. Lens subluxation was observed in the 3 species at ocriplasmin concentrations in the vitreous at or above 41 mcg/mL, a concentration 1.4-fold above the intended clinical concentration in the vitreous of 29 mcg/mL. Intraocular hemorrhage was observed in rabbits and monkeys.

A second intravitreal administration of ocriplasmin (28 days apart) in monkeys at doses of 75 mcg/eye (41 mcg/mL vitreous) or 125 mcg/eye (68 mcg/mL vitreous) was associated with lens subluxation in all ocriplasmin treated eyes. Sustained increases in IOP occurred in two animals with lens subluxation. Microscopic findings in the eye included vitreous liquefaction, degeneration/disruption of the hyaloideocapsular ligament (with loss of ciliary zonular fibers), lens degeneration, mononuclear cell infiltration of the vitreous, and vacuolation of the retinal inner nuclear cell layer. These doses are 1.4-fold and 2.3-fold the intended clinical concentration in the vitreous of 29 mcg/mL, respectively.


The efficacy and safety of Jetrea was demonstrated in two multicenter, randomized, double masked, vehicle-controlled, 6 month studies in patients with symptomatic vitreomacular adhesion (VMA). A total of 652 patients (Jetrea 464, vehicle 188) were randomized in these 2 studies. Randomization was 2:1 (Jetrea:vehicle) in Study 1 and 3:1 in Study 2.

Patients were treated with a single injection of Jetrea or vehicle. In both of the studies, the proportion of patients who achieved VMA resolution at Day 28 (i.e., achieved success on the primary endpoint) was significantly higher in the ocriplasmin group compared with the vehicle group through Month 6 (Table 2 and Figure 7).

Total posterior vitreous detachment (PVD) induction in symptomatic vitreomacular adhesion patients was evaluated by B-scan ultrasound. A statistically significantly higher percentage of Jetrea treated patients achieved total PVD at Day 28 compared to vehicle treated patients in Study 1 (16% vs. 6%; p=0.014) and in Study 2 (11% vs. 0%; p<0.01).

The number of patients with at least 3 lines increase in visual acuity was numerically higher in the ocriplasmin group compared to vehicle in both trials, however, the number of patients with at least a 3 lines decrease in visual acuity was also higher in the ocriplasmin group in one of the studies (Table 3 and Figure 8).
