“Prior to the launch of Inveltys, all available post-surgical corticosteroids were approved with four-times-a-day dosing. This more frequent dosing requirement can lead to issues for both doctors and patients.

Corticosteroids are the foundation of therapy for post-ocular surgery care, with the key goal of controlling inflammation and pain which is caused by surgical trauma to the eye. The use of ocular steroids post-surgery is to achieve a rapid reduction of inflammation and to promote healing of the eye. Therefore, ensuring close adherence to the steroid regimen is a critical factor for physicians in the post-surgery care of the patient and eventual overall success of the procedure. Inveltys is the first ocular corticosteroid approved for BID dosing,” Kim Brazzell, PhD, chief medical officer of Kala, told Healio.com/OSN.

Inveltys successfully completed two phase 3 clinical trials that showed statistical significance for its primary efficacy endpoints of complete resolution of inflammation and pain at postoperative day 8 through day 15 compared with placebo.

“We believe that Inveltys will address some key unmet needs for ocular surgery patients by delivering strong efficacy with a favorable safety profile and with a less frequent dosing regimen of BID compared to QID for all existing corticosteroids,” Brazzell told Healio.com/OSN. 

Approval of Inveltys is the next triumph in ocular drug delivery. Using mucus penetrating particle technology to enhance penetration of loteprednol, the drug demonstrated efficacy in controlling postoperative pain and inflammation with twice daily dosing. It is now much easier for our surgical patients to get in all of their postop drops, with an active compound that is trusted by surgeons for its safety.

Mucus Penetrating Particle Technology (MPP)

A method that could provide more uniform and longer-lasting drug and gene delivery to mucosal surfaces holds the potential to greatly improve the effectiveness of prophylactic and therapeutic approaches for numerous diseases and conditions, including sexually transmitted infections, cystic fibrosis, chronic rhinosinusitis, inflammatory bowel disease, and glaucoma to name a few. However, the body’s natural defenses, including adhesive, rapidly cleared mucus linings coating nearly all entry points to the body not covered by skin, has limited the effectiveness of drug and gene delivery by nanoscale delivery systems. This article discusses the recent development of the “mucus-penetrating particle” or “MPP” nanotechnology, and how it has been used to both enhance understanding of the nanoscale barrier properties of human mucus secretions, and to achieve more uniform and longer-lasting drug delivery to mucosal tissues following topical administration. Drug loaded MPPs possess non-adhesive coatings that allow them to rapidly penetrate mucus layers through openings in the mucus mesh at rates nearly as fast as they would penetrate pure water. Critically, MPPs allow enhanced drug and gene delivery to mucosal tissues without diminishing the protective function of mucus. Recent progress in the development of MPPs as a biophysical tool to probe the length-scale dependent rheological properties of mucosal secretions and as a method for drug and gene delivery is highlighted.

MPP for Ocular Drug Delivery Research

Enhanced drug exposure to the ocular surface typically relies on inclusion of viscosity-enabling agents, whereas delivery to the back of the eye generally focuses on invasive means, such as intraocular injections. Using our novel mucus-penetrating particle (MPP) technology, which rapidly and uniformly coats and penetrates mucosal barriers, we evaluated if such drug formulations could increase ocular drug exposure and improve topical drug delivery.

Results

We demonstrated in animals that administration of LE-MPP increased exposure at the ocular surface and posterior compartments. Furthermore, using a rabbit vascular leakage model, we demonstrated that biologically effective drug concentrations of LE were delivered to the back of the eye using the MPP technology. We also demonstrated that a novel RTKi formulated as MPPs provided drug levels to the back of the eye above its cellular inhibitory concentration.

Fix your cataracts and never wear glasses again.

Conclusions

Topical dosing of MPPs of LE or KAL821 enhanced drug exposure at the front of the eye, and delivered therapeutically relevant drug concentrations to the back of the eye, in animals.

Translational Relevance

These preclinical data support using MPP technology to engineer topical formulations to deliver therapeutic drug levels to the back of the eye and could provide major advancements in managing sight-threatening diseases.

Contraindications 

INVELTYS is contraindicated in most viral diseases of the cornea and conjunctiva including epithelial herpes simplex keratitis (dendritic keratitis), vaccinia, and varicella, and also in mycobacterial infection of the eye and fungal diseases of ocular structures. 

Warnings and Precautions

  • Intraocular pressure (IOP) increase – prolonged use of corticosteroids may result in glaucoma with damage to the optic nerve, defects in visual acuity and fields of vision. If this product is used for 10 days or longer, IOP should be monitored. 
  • Cataracts – Use of corticosteroids may result in posterior subcapsular cataract formation. 
  • Delayed healing – Use of steroids after cataract surgery may delay healing and increase the incidence of bleb formation. In those diseases causing thinning of the cornea or sclera, perforations have been known to occur with the use of topical steroids. The initial prescription and renewal of the medication order should be made by a physician only after examination of the patient with the aid of magnification such as slit lamp bio-microscopy and, where appropriate, fluorescein staining. 
  • Bacterial infections – Prolonged use of corticosteroids may suppress the host response and thus increase the hazard of secondary ocular infections. In acute purulent conditions, steroids may mask infection or enhance existing infection. 
  • Viral infections – Use of a corticosteroid medication in the treatment of patients with a history of herpes simplex requires great caution. Use of ocular steroids may prolong the course and may exacerbate the severity of many viral infections of the eye (including herpes simplex). 
  • Fungal Infections – Fungal infections of the cornea are particularly prone to develop coincidentally with long-term local steroid application. Fungus invasion must be considered in any persistent corneal ulceration where a steroid has been used or is in use. 

Adverse Reactions 

The most common adverse drug reactions were eye pain (1%) and posterior capsular opacification (1%). These reactions may have been the consequence of the surgical procedure.

FDA Accepts Inveltys: First Two Times Daily Ocular Steroid

Inveltys (loteprednol etabonate ophthalmic suspension 1%) is the first twice-daily ocular steroid for the therapy of inflammation and pain after ocular surgical procedure to be approved by the FDA.

” Prior to the launch of Inveltys, all offered post-surgical corticosteroids were approved with four-times-a-day application. This more frequent dosing requirement can bring about concerns for both doctors and also patients. Corticosteroids are the foundation of treatment for post-ocular surgical treatment, with the vital objective of controlling inflammation and pain which is brought on by surgical trauma to the eye. Making use of eye steroids post-surgery is to accomplish a quick reduction of inflammation and also to promote recovery of the eye. Consequently, guaranteeing close adherence to the steroid regimen is an essential factor for medical professionals in the post-surgery treatment of the patient as well as ultimate overall success of the treatment. Inveltys is the first eye corticosteroid authorized for BID dosing, (as compared to more frequent dosing earlier),” Kim Brazzell, PhD, chief medical officer of Kala, told Healio.com/ OSN.

Inveltys efficiently finished two phase 3 clinial trials that showed statistical significance for its key efficacy endpoints of full resolution of inflammation and also pain at postoperative day 8 through day 15 compared with placebo.

” Our company believes that Inveltys will resolve some vital unmet requirements for eye surgical treatment patients by delivering solid efficiency with a positive safety record and with a much less regular application program of BID compared to QID for all existing corticosteroids,” Brazzell informed Healio.com/ OSN.

Authorization of Inveltys is the next victory in ocular medication delivery. Utilizing mucus penetrating particle technology to enhance penetration of loteprednol, the medicine showed efficacy in regulating postoperative discomfort and also inflammation with twice everyday dosing. 

Mucus Penetrating Particle Technology (MPP)

A method that can provide even more uniform and also longer-lasting medication as well as gene delivery to mucosal surface areas holds the possibility to substantially improve the efficiency of prophylactic as well as therapeutic strategies for countless illnesses and also problems, including sexually transmitted infections, cystic fibrosis, persistent rhinosinusitis, inflammatory bowel disease, and glaucoma to name a few.

It was demonstrated in animals that management of LE (loteprednol etabonate ophthalmic suspension 1%) – MPP boosted exposure at the eye surface area as well as posterior areas. In other words, use of MPP technology boosted drug delivery where needed. In addition, using a rabbit vascular leakage model, it was demonstrated that naturally reliable medicine concentrations of LE were delivered to the back of the eye utilizing the MPP technology. It was additionally demonstrated that a novel receptor tyrosine kinase inhibiting (RTKi) formulated as MPPs provided medicine levels to the rear of the eye above its cellular inhibitory concentration.

Conclusions

Topical dosing of MPPs of LE improved drug exposure at the front of the eye, and also delivered therapeutically appropriate medicine focus to the rear of the eye, in pets.


Translational Significance
These preclinical data support using MPP technology to engineer topical formulations to supply therapeutic medicine levels to the rear of the eye as well as might offer major developments in taking care of sight-threatening conditions.

Contraindications
INVELTYS is contraindicated in most viral conditions of the cornea and also conjunctiva consisting of epithelial herpes, simplex keratitis (dendritic keratitis), vaccinia, as well as varicella, as well as also in mycobacterial infection of the eye as well as fungal diseases of ocular structures. It should not be used in the presence of these conditions.


Warnings as well as Precautions.
– Intraocular stress (IOP) increase – long term use of corticosteroids may lead to glaucoma, with damage to the optic nerve, defects in visual acuity and field of vision. If this product is made use of for 10 days or longer, IOP must be monitored.


– Cataracts – Use of corticosteroids may result in posterior subcapsular cataract development.
– Delayed recovery – Use of steroids after cataract surgical treatment may delay healing as well as boost the occurrence of bleb development. In disease creating thinning of the cornea or sclera, perforations have actually been understood to accompany use of topical steroids. The first prescription and renewal of the drug order need to be made by a physician only after evaluation of the patient with the aid of magnification techniques such as slit lamp bio-microscopy and, where appropriate, fluorescein staining. Use of the drug is to be made only by prescription of your ophthalmologist and under constant supervision and monitoring.
– Bacterial infections – Prolonged use of corticosteroids might reduce the host action as well as hence boost the danger of additional ocular infections. In acute purulent problems, steroids may mask infection or enhance existing infection.
– Viral infections – Use of a corticosteroid medication in the treatment of patients with a background of herpes simplex calls for great care. Use of ocular steroids might extend the course and might intensify the extent of several viral infections of the eye (including herpes simplex).
– Fungal Infections– Fungal infections of the cornea are especially prone to develop together with long-term local steroid application. Fungus invasion must be thought about in any persistent corneal ulceration where a steroid has been made use of or remains in use. Therefore it is imperative that you remain in touch with your ophthalmologist while making use of corticosteroids.

Adverse Reactions

One of the most common adverse medication responses were eye discomfort (1%) and also posterior capsular opacification (1%). These reactions might have been the consequence of the surgery.
