Vernal keratoconjunctivitis Disease Understanding and Treatment Algorithm

Vernal keratoconjunctivitis (VKC) is a bilateral, usually seasonally recurrent, allergic inflammation of the conjunctiva, characterized by limbal gelatinous hypertrophy and/or upper tarsal giant conjunctival papillae. It is an IgE-mediated and T cell-mediated disease, leading to a chronic inflammation in which eosinophil, lymphocyte, and structural cell activation are involved. The disease may present in three clinical forms: tarsal, limbal and mixed form.

VKC mostly affects children and young adults living in warm climates worldwide. It begins typically in the first decade of life and resolves spontaneously after puberty even though in the most severe cases it can leave permanent lesions. It is characterized by intense itching, tearing, mucous secretions, and severe photophobia.

Diagnosis

There are no established diagnostic criteria for VKC and the diagnosis is based on the characteristic signs and symptoms of the disease. Because of no precise diagnostic criteria have been established, many mild or atypical cases may escape the diagnosis. Hyperemia, itching, photophobia, tearing and mucus discharge are typical symptoms of VKC. Large papilla on the upper tarsal conjunctiva and corneoscleral junction are hallmarks of VKC.

Treatment

Currently, there is no defined standard treatment algorithm for VKC, but there are many options available, and treatment should be tailored to the individual. Individuals treated should be monitored closely for the development of any corneal complications.

The current treatment options include mast cell stabilizers, antihistamines, nonsteroidal anti-inflammatory drugs (NSAIDs), topical corticosteroids, cyclosporine, and tacrolimus.

Mast cell stabilizers prevent the degranulation of mast cells. Commonly used mast cell stabilizers include cromolyn sodium and lodoxamide, which are frequently used as first-line therapy. Antihistamines are sometimes used in the treatment of VKC. They are most often used in alleviating the symptoms of mild disease, but they have limited utility in severe cases. More recent medications that combine antihistamine properties with mast cell stabilization include ketotifen and olopatadine.

NSAIDs (preservative‐free diclofenac (0.1%) eye drops) may be used in conjunction with other topical anti-inflammatory medications to provide rapid relief of symptoms; however, they have limited utility in those patients with corneal involvement.

Topical corticosteroids are one of the most effective drugs to control the signs and symptoms of VKC. Because of complications associated with their prolonged use, these are not prescribed as first‐line treatment. Cyclosporine, a fungal metabolite, decreases the signs and symptoms of VKC. Low doses of cyclosporine are used in some cases of VKC.

Tacrolimus has shown efficacy in clinical trials and it can be also used in patients with corneal involvement. Mitomycin‐C (0.01%) eyedrops were shown to decrease the mucous discharge, conjunctival hyperemia and limbal edema in VKC patients refractory to topical steroids and mast‐cell stabilizers. The allergen-specific immunotherapy (SIT) is indicated only when a clearly defined systemic hypersensitivity to identified allergens exists.

Marketed Drugs

Verkazia/Verkacia: Santen

Verkazia/Verkacia (0.1% cyclosporine), an immunomodulator that targets the underlying cause of the inflammation at the surface of the eye, controls the allergic response and inflammation. It is approved for the treatment of severe VKC in children from 4 years of age and adolescents.

Verkazia works differently to other licensed treatments, as it directly targets the underlying cause of the inflammation at the surface of the eye, controlling the allergic response and inflammation. It can be used over a sustained period which means that the use of steroids can be reduced. In clinical trials, Verkazia has been shown to significantly improve damage to the surface of the eye and reduce symptoms of severe VKC in children and adolescents (54% improvement vs. the control group given cationic emulsion. Verkazia was shown to improve the main symptoms of VKC: 68% improvement in light sensitivity; 58% in tearing; 72% in itching; and 67% in discharge.

Lodoxamide/Alomide: Novartis Pharmaceuticals/Alcon

Lodoxamide 0.1% (Alomide) is a mast cell stabilizer that is approximately 2,500 times more potent than cromolyn in the prevention of histamine release in several animal models. Lodoxamide is effective in reducing tryptase and histamine levels and the recruitment of inflammatory cells in the tear fluid after allergen challenge, as well as tear eosinophil cationic protein and leukotrienes (BLT and CysLT1) when compared to cromolyn. In early clinical trials lodoxamide (0.1%) was shown to deliver greater and earlier relief in patients with more chronic forms, such as VKC, including upper tarsal papilla, limbal signs (papilla, hyperemia, and Trantas' dots) and conjunctival discharge, and to improve epithelial defects seen in the chronic forms of conjunctivitis (VKC, GPC) than cromolyn. In patients with allergic conjunctivitis, it is approved for the treatment of VKC at a concentration of 0.1% four times daily. Lodoxamide may be used continuously for 3 months in children older than 2 years of age.

Talymus/Tacrolimus: Senju Pharmaceutical

Tacrolimus is a strong, nonsteroidal immune suppressant isolated from Streptomyces tsukubaensi. It binds to FK506-binding proteins in T-lymphocytes and inhibits calcineurin activity. Calcineurin inhibition suppresses dephosphorylation of the nuclear factor of activated T-cells and its transfer into the nucleus, which suppresses the formation of T-helper (Th) 1 (interleukin [IL]-2, interferon γ) and Th2 cytokines (IL-4, IL-5). Tacrolimus also inhibits histamine release from mast cells, which is thought to alleviate allergic symptoms. Tacrolimus is up to 100 times more potent than cyclosporine.

Tacrolimus ointment is used widely for the treatment of atopic dermatitis. Topical tacrolimus (0.02–0.1%) has also been used to treat giant papillary conjunctivitis, AKC, and VKC, with good results. Furthermore, a tacrolimus 0.1% ophthalmic suspension has been used for the treatment of AKC and VKC with only 4 weeks of follow-up. Tacrolimus, 0.1% ointment, is a safe and effective treatment for VKC refractory to standard treatment and is used as a substitute for steroid treatments used to controlled disease activity.

Nomacopan: Akari Therapeutics

Nomacopan, which is a second-generation complement inhibitor, acts on complement component-C5, preventing the release of C5a and formation of C5b-9 (also known as the membrane attack complex, or MAC), and independently also inhibits leukotriene B4, or LTB4, activity, both elements that are co-located as part of the immune/inflammatory response. It is a small recombinant protein (16,740 Da) derived from a protein originally discovered in the saliva of the Ornithodoros moubata tick, where it modulates the host immune system to allow the parasite to feed without alerting the host to its presence or provoking an immune response.

Additionally, Nomacopan's biophysical properties allow it to be potentially used in a variety of formulations, including subcutaneous, intravenous, topical or inhaled routes of administration. Currently, Akari Therapeutics is investigating the molecule in phase I/II clinical trial in patients with atopic keratoconjunctivitis (including VKC, Sjögren’s syndrome, and mucous membrane pemphigoid).

Vernal keratoconjunctivitis Market Outlook

Treatment of VKC requires multiple approaches that include conservative measures and pharmacologic treatment. Patients and parents should be made aware of the prolonged duration of disease, its chronic evolution, and possible complications. Treatment should be based on the duration and frequency of symptoms and the severity of corneal involvement.

Currently available topical drugs for allergic conjunctivitis belong to several pharmacologic classes, such as vasoconstrictors, antihistamines, mast cell stabilizers, ‘dual-acting’ agents (with antihistaminic and mast cell stabilizing properties), non-steroidal anti-inflammatory agents, corticosteroids, and immunosuppressive drugs.

Mast cell stabilizers are the first-line drugs for VKC. Several studies have demonstrated the efficacy of 2% and 4% sodium cromoglicate (DSCG, cromolyn), nedocromil sodium 2%, lodoxamide tromethamine 0.1%, and spaglumic acid 4%.

Ocular drugs with antihistaminic activity may offer therapeutic advantages to patients with allergic conjunctivitis, including VKC, by inhibiting proinflammatory cytokine secretion from conjunctival epithelial cells. The first-generation antihistamines pheniramine and antazoline have a long safety record. The newer antihistamines such as levocabastine hydrochloride 0.5% and emedastine difumarate 0.05% have a longer duration of action (4–6 h) and are better tolerated than their predecessors.

A meta-analysis of randomized clinical trials in VKC showed a large number of studies evaluated the efficacy of common anti-allergic eye drops (levocabastine, lodoxamide, mipragoside, N-acetyl aspartyl glutamic acid, nedocromil sodium, DCG). Among these, lodoxamide appeared to be the most effective.

Papilock mini and Verkazia both produced by Santen (Osaka, Japan) are specifically indicated for the treatment of VKC.

Generally, NSAIDs employed in ocular allergy treatment inhibit both cyclooxygenase (COX)-1 and COX-2 enzymes. Also, Ketorolac, diclofenac and pranoprofen may be valid alternatives to steroids, since they have a proven effect on itching, intercellular adhesion molecule-1 expression, and tear tryptase levels. Indomethacin 1%, ketorolac 0.5%, and diclofenac 0.1% have shown effectiveness in the treatment of VKC.

Aspirin 0.5–1 g/day has been shown as a steroid-sparing factor in the treatment of VKC; however, it should be used with caution because of the well-known possible side effects.

In severe cases, systemic treatment with T-lymphocyte signals transduction inhibitors such as Cyclosporine A or tacrolimus may ameliorate both the dermatologic and ocular manifestations in critical patients who are refractory to conventional treatment.

Omalizumab, an anti-IgE recombinant, humanized, non-anaphylactogenic antibody, directed against the receptor-binding domain of IgE, may be used in VKC patients with high levels of total serum IgE. Calcineurin inhibitors are off-label treatments in the European Union.

As discussed, the current treatment for VKC depends solely on the use of antihistamines, mast cell inhibitors, and several other classes. But till now the treatment is only supportive and is not that effective. But due to the advancement of technology and a better understanding of the disease, several companies are trying to modify the treatment of VKC.

According to DelveInsight, VKC global market is expected to change in the study period 2017–2030.
