Drug Details [pdf]

  • 1 INDICATIONS AND USAGE

    Ryzumvi is indicated for the treatment of pharmacologically-induced mydriasis produced by adrenergic agonists (e.g., phenylephrine) or parasympatholytic (e.g., tropicamide) agents.

  • 2 DOSAGE AND ADMINISTRATION

    Adults and pediatric patients aged 12 years or older: Instill 1 or 2 drops in each dilated eye following the completion of the ophthalmic examination or procedure. If 2 drops are instilled, the second drop should be administered 5 minutes after the first drop.

    Pediatric patients aged 3 to 11 years: Instill 1 drop in each dilated eye following the completion of the ophthalmic examination or procedure.

    One single-patient-use vial can be used to dose each dilated eye. Discard the single-patient-use vial immediately after use.

  • 3 DOSAGE FORMS AND STRENGTHS

    Ophthalmic solution: clear and colorless solution containing phentolamine 0.75% in a single-patient-use vial.

  • 4 CONTRAINDICATIONS

    None.

  • 5 WARNINGS AND PRECAUTIONS

    5.1 Uveitis

    Ryzumvi is not recommended when active ocular inflammation (e.g. iritis) is present because adhesions (synechiae) may form between the iris and the lens.

    5.2 Potential for Eye Injury or Contamination

    To avoid the potential for eye injury or contamination, care should be taken to avoid touching the vial tip to the eye or to any other surface.

    5.3 Use with Contact Lenses

    Contact lens wearers should be advised to remove their lenses prior to the instillation of Ryzumvi and wait 10 minutes after dosing before reinserting their contact lenses.

  • 6 ADVERSE REACTIONS

    6.1 Clinical Trials Experience

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

    Ryzumvi was evaluated in 642 subjects in clinical trials across various subject populations. The most common ocular adverse reactions reported in >5% of subjects were instillation site discomfort including pain, stinging, and burning (16%) and conjunctival hyperemia (12%). The only non-ocular adverse reaction reported in >5% of subjects was dysgeusia (6%).

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary

    There are no available data with Ryzumvi administration in pregnant women to inform a drug-associated risk. In animal toxicology studies, when phentolamine was administered orally to pregnant mice and rats during the period of organogenesis skeletal immaturity and decreased growth was observed in the offspring at doses at least 24-times the recommended clinical dose. Additionally, a lower rate of implantation was seen in pregnant rats treated with phentolamine administered at least 60-times the recommended clinical dose. No malformations or embryofetal deaths were observed in the offspring of pregnant mice, rats, and rabbits administered phentolamine during the period of organogenesis at doses of at least 24-, 60-, and 20-times, respectively, the recommended clinical dose (see Data). Ryzumvi should only be used during pregnancy if the potential benefit justifies the potential risk to the fetus.

    Data

    Animal Data

    Oral administration of phentolamine to pregnant rats and mice at doses at least 24-times the recommended clinical dose (based on a body weight per surface area (mg/m2) comparison with a 60-kg human) resulted in slightly decreased growth and slight skeletal immaturity of the fetuses. Immaturity was manifested by increased incidence of incomplete or unossified calcanei and phalangeal nuclei of the hind limb and of incompletely ossified sternebrae. At oral phentolamine doses at least 60-times the recommended clinical dose (based on a mg/m2 comparison with a 60-kg human), a slightly lower rate of implantation was found in rats. Phentolamine did not affect embryonic or fetal development in rabbits at oral doses at least 20-times the recommended dose (based on a mg/m2 comparison with a 60-kg human). No malformations or embryofetal deaths were observed in the rat, mouse or rabbit studies.

    8.2 Lactation

    Risk Summary

    There is no information regarding the presence of phentolamine in human milk, the effects on the breastfed infants, or the effects on milk production during lactation to inform risk of phentolamine ophthalmic solution 0.75% to an infant. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Ryzumvi and any potential adverse effects on the breastfed child from Ryzumvi.

    8.4 Pediatric Use

    The safety and effectiveness of Ryzumvi have been established in pediatric patients aged 3 to 17 years. No overall differences have been observed between pediatric and adult subjects [see Clinical Studies (14)].

    8.5 Geriatric Use

    No overall differences in safety and effectiveness have been observed between elderly and younger adult subjects.

  • 10 OVERDOSAGE

    No deaths due to acute poisoning with phentolamine have been reported. Overdosage with parenterally administered phentolamine is characterized chiefly by cardiovascular disturbances, such as arrhythmias, tachycardia, hypotension, and possibly shock. In addition, the following might occur: excitation, headache, sweating, visual disturbances, nausea, vomiting, diarrhea, or hypoglycemia. There is no specific antidote; treatment consists of appropriate monitoring and supportive care. Substantial decreases in blood pressure or other evidence of shock-like conditions should be treated vigorously and promptly.

  • 11 DESCRIPTION

    Ryzumvi (phentolamine ophthalmic solution) 0.75% is a sterile, clear and colorless solution for topical ophthalmic use containing 1% phentolamine mesylate (equivalent to 0.75% phentolamine). The product does not contain an anti-microbial preservative. The chemical name of phentolamine mesylate is 3-[[(4,5-dihydro-1H-imidazol-2-yl)methyl](4-methylphenyl)amino]phenol; methanesulfonic acid (parent phentolamine: [3-[[(4,5-dihydro-1H-imidazol-2-yl)methyl](4-methylphenyl)amino]phenol]) and the molecular formula is C18H23N3O4S (parent C17H19N3O). The molecular weight of phentolamine mesylate is 377.46 and the chemical structure is:

    Phentolamine Mesylate Structural Formula

    Each mL of Ryzumvi contains phentolamine mesylate 10 mg as the active ingredient (equivalent to 7.5 mg phentolamine as the free base). Inactive ingredients are: mannitol, sodium acetate trihydrate, and water for injection. Hydrochloric acid and/or sodium hydroxide are added to adjust pH (4.5 to 5.5), and the solution is overlaid with nitrogen.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Ryzumvi is a relatively non-selective alpha-1 and alpha-2 adrenergic antagonist. Dilation of the pupil is primarily controlled by the radial iris dilator muscles surrounding the pupil; these muscles are activated by the alpha-1 adrenergic receptors. Phentolamine reversibly binds to these receptors on the iris dilator muscle, thereby reducing pupil diameter. Phentolamine directly antagonizes the mydriatic effect of an α-1 adrenergic agonist, and indirectly reverses mydriasis induced by muscarinic antagonist effects on the iris sphincter muscle.

    12.2 Pharmacodynamics

    The onset of action after administration of Ryzumvi generally occurs in 30 minutes, with the maximal effect seen in 60 to 90 minutes, and the effect lasting at least 24 hours.

    12.3 Pharmacokinetics

    Phentolamine systemic exposure was evaluated in a Phase 3 trial (MIRA-3) following topical ocular administration of a total of 3 drops, each of 0.03 mL, of phentolamine ophthalmic solution 0.75%. The peak concentration levels are achieved between 15 minutes and 1 hour after dosing with the median value of 0.45 ng/mL.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    Carcinogenesis

    Carcinogenicity studies with Ryzumvi have not been conducted.

    Mutagenesis

    Phentolamine was not mutagenic in the in-vitro bacterial reverse mutation (Ames) assay. In the in-vitro chromosomal aberration study in Chinese hamster ovary cells, numerical aberrations were slightly increased after a 4-hour exposure to phentolamine without metabolic activation, and structural aberrations were slightly increased after a 4-hour exposure to phentolamine with metabolic activation only at the highest concentrations tested, but neither numerical nor structural aberrations were increased after a 20-hour exposure without metabolic activation. Phentolamine was not clastogenic in two in-vivo mouse micronucleus assays.

    Impairment of Fertility

    The effect of phentolamine on female fertility has not been studied. Male rats treated with oral phentolamine for nine weeks (four weeks prior to mating, 3 weeks during the mating period and 2 weeks after mating) were mated with untreated females. At doses up to 648-times human therapeutic exposure levels at the Cmax, no adverse effects on male fertility parameters or on reproductive parameters in the untreated females mated with the treated males were observed.

  • 14 CLINICAL STUDIES

    The efficacy of Ryzumvi for the reversal of mydriasis was demonstrated in two, randomized, double-masked, vehicle-controlled trials; MIRA-2 (NCT#04620213) and MIRA-3 (NCT#05134974). A total of 553 subjects, aged 12 to 80 years, who had mydriasis induced by instillation of phenylephrine or tropicamide or a combination of hydroxyamphetamine hydrobromide and tropicamide (Paremyd) were randomized. Subjects with light and dark irides were included in both trials. Two drops (study eye) or one drop (fellow eye) of Ryzumvi or placebo (vehicle) were administered one hour after instillation of the mydriatic agent. The percentage of subjects with study eyes returning to ≤0.2 mm from baseline pupil diameter was statistically significantly greater (p<0.01) at all time points measured from 60 minutes through 24 hours in the Ryzumvi group compared with the placebo (vehicle) group across both of the MIRA-2 and MIRA-3 trials (see Figure 1).

    Figure 1. Percentage of subjects with study eyes returning to ≤0.2 mm from baseline pupil diameter by time point in the MIRA-2 and MIRA-3 Trials

    The efficacy of MIRA-2 and MIRA-3 also showed that the change from maximum pupil dilation in study eyes and fellow eyes was statistically significantly different between the Ryzumvi-treated group and the placebo-treated group at all time points from 60 minutes through 24 hours post-treatment (p<0.01). Pupil size at 24 hours was 1 mm smaller than baseline. These results were consistent regardless of whether phenylephrine or tropicamide/Paremyd were used as mydriatic agents (Figure 2, Figure 3; respectively).

    The efficacy of Ryzumvi was similar for all age ranges including pediatric subjects aged 3 to 17 years. Pediatric subjects aged 12 to 17 years (n=27) were treated in MIRA-2 and MIRA-3 and pediatric subjects, aged 3 to 11 years (n=11) were treated in MIRA-4, (NCT#05223478).
