WATERTOWN, Mass., Nov. 15, 2021 (GLOBE NEWSWIRE) — Kala Pharmaceuticals, Inc. (NASDAQ:KALA), a commercial-stage biopharmaceutical company focused on the discovery, development and commercialization of innovative therapies for diseases of the eye, today reported financial results for the third quarter ended September 30, 2021 and provided a corporate update.

“We have made progress toward our goal of providing patients and physicians with a portfolio of innovative medicines and product candidates that can better treat diseases of the front and back of the eye,” said Mark Iwicki, Chief Executive Officer of Kala. “We continue to receive positive feedback from physicians and patients on EYSUVIS and saw 19% prescription growth in the third quarter compared to the prior quarter. In parallel, we continue to invest in advancing our pipeline and today announced the acquisition of Combangio and its lead product candidate, now known as KPI-012, a novel biologic for the treatment of rare ocular surface diseases. We believe that together with our rTKI and SEGRM programs, KPI-012 will serve as a key foundation for our long-term growth. We look forward to submitting an investigational new drug application to the U.S. Food and Drug Administration for KPI-012 and, subject to regulatory clearance, initiating a Phase 2/3 trial for persistent corneal epithelial defect in the third quarter of 2022.”

Third Quarter and Recent Business Highlights:

EYSUVIS® (loteprednol etabonate ophthalmic suspension) 0.25%: EYSUVIS became commercially available in January 2021 as the first and only FDA-approved medicine for the short-term (up to two weeks) treatment of the signs and symptoms of dry eye disease. Data from Symphony Health and the EYSUVIS patient hub indicate that 18,537 EYSUVIS prescriptions were filled in the third quarter of 2021, representing quarter-over-quarter growth of 19%. As of the week ended November 5, 2021, 50,862 prescriptions of EYSUVIS, including over 6,652 refill prescriptions, written by more than 5,502 unique prescribers, have been filled since the product launched in early January 2021.

As of the end of the third quarter of 2021, Kala has secured coverage for more than 99 million commercial lives, which represents approximately 60% of all commercially insured lives. In the third quarter, EYSUVIS added an additional 4.5 million covered lives through health plans and existing contracts with Express Scripts and OptumRx. Kala continues to engage in contract discussions with other commercial health plans and expects to further expand formulary coverage in the coming months. In addition, as of the end of the third quarter of 2021, EYSUVIS achieved 10% Medicare Part D coverage, an increase of 3% for the quarter and total coverage for EYSUVIS is 4.5 million Medicare Part D lives.

INVELTYS® (loteprednol etabonate ophthalmic suspension) 1%: 37,410 INVELTYS prescriptions were reported by Symphony Health in the third quarter of 2021, compared to 41,103 prescriptions reported in the second quarter of 2021. INVELTYS prescriptions declined in the quarter due to continued weakness in the ocular surgery market from COVID-19 as well as the removal of INVELTYS from the CVS/Caremark formulary coverage list. Kala believes that INVELTYS prescriptions and revenues will return to growth as the number of ocular surgeries return to pre-COVID levels. However, the Company is unable to project the specific timing or quantify the specific potential impact on future revenues given the continued uncertainty around the impact and duration of the COVID-19 pandemic on elective procedures, which includes ocular surgeries.

Development-Stage Pipeline: In a separate press release issued today, Kala announced the acquisition of Combangio, Inc., a private, clinical-stage company developing a novel investigational secretome therapy, now known as KPI-012, to address the complex wound healing process in persistent corneal epithelial defect (PCED) and other severe ocular diseases driven by impaired corneal healing. KPI-012 is initially in clinical development for the treatment of PCED, a rare disease with an estimated incidence in the U.S. of 100,000 cases per year and 238,000 cases per year in the U.S., E.U. and Japan combined, and has received Orphan Designation for the treatment of PCED by the U.S. Food and Drug Administration (FDA). Kala plans to submit an investigational new drug (IND) application to FDA for KPI-012 and, subject to regulatory clearance, initiate a Phase 2/3 trial of KPI-012 in the third quarter of 2022.

In addition, Kala continues to progress its development programs targeted to address front and back of the eye diseases. These programs, all of which are new chemical entities (NCEs), include a receptor Tyrosine Kinase Inhibitor candidate (rTKI), KPI-287, and selective glucocorticoid receptor modulators (SEGRMs). KPI-287 is administered via suprachoroidal delivery for the treatment of retinal diseases, including wet age-related macular degeneration (wet AMD). Kala expects to announce preclinical pharmacokinetics and efficacy data in the first quarter of 2022.

SEGRMs are a novel class of therapies designed to modify the downstream activity of the glucocorticoid receptor to exhibit the anti-inflammatory and immunomodulatory properties of corticosteroids while potentially avoiding the typical safety concerns of steroids. Kala expects to determine a development candidate in the first half of 2022. Kala owns all intellectual property and worldwide rights to its pipeline candidates.

Financial Results:
The financial results below contain both GAAP and non-GAAP financial measures. The non-GAAP financial measures exclude stock-based compensation expense, loss on extinguishment of debt, non-cash interest expense and depreciation and amortization. See “Non-GAAP Financial Measures” below; for a full reconciliation of Kala’s GAAP to non-GAAP financial measures, please refer to the tables at the end of this press release.

• Cash Position: As of September 30, 2021, Kala had cash and cash equivalents of $124.5 million, compared to $149.6 million of cash, cash equivalents and short-term investments as of June 30, 2021. This decrease primarily reflects cash used in operations. Cash and cash equivalents as of September 30, 2021 do not reflect the $5 million paid as upfront consideration for the acquisition of Combangio, which was announced in a separate press release this morning. Based on its current plans, including the costs to acquire Combangio and develop KPI-012, Kala anticipates that its cash resources as of September 30, 2021, together with anticipated revenue from EYSUVIS and INVELTYS and certain cost containment measures, will enable it to fund its operations until the second quarter of 2023.

Third Quarter 2021 Financial Results

• Net Product Revenues: For the quarter ended September 30, 2021, Kala reported net product revenues of $3.1 million, consisting of $1.83 million of net revenues from EYSUVIS sales and $1.24 million of net revenues from INVELTYS sales, compared to $2.2 million from INVELTYS sales for the same period in 2020.
• Cost of Product Revenues: For the quarter ended September 30, 2021, cost of product revenues was $0.9 million, compared to $0.7 million for the same period in 2020. Cost of product revenues increased due to units of EYSUVIS sold. Non-GAAP cost of product revenues was $0.9 million for the quarter ended September 30, 2021, compared to $0.7 million for the same period in 2020.
• SG&A Expenses: For the quarter ended September 30, 2021, selling, general and administrative (SG&A) expenses were $25.3 million, compared to $23.9 million for the same period in 2020.

The weighted average number of shares used to calculate net loss per share was 65.1 million for the quarter ended September 30, 2021 and 56.0 million for the quarter ended September 30, 2020.

Financial Results for the Nine Months ended September 30, 2021

• Net Product Revenues: For the nine months ended September 30, 2021, Kala reported net product revenues of $9.4 million, consisting of $5.1 million of net revenues from EYSUVIS sales and $4.3 million of net revenues from INVELTYS sales, compared to $4.1 million of net revenue from INVELTYS sales for the same period in 2020.
• Cost of Product Revenues: For the nine months ended September 30, 2021, cost of product revenues was $2.7 million, compared to $1.8 million for the same period in 2020. The increase was primarily due to units of EYSUVIS sold as well as the increase in total INVELTYS units sold during the nine months ended September 30, 2021, compared to the same period in 2020, partially offset by a reserve for excess INVELTYS inventory of $0.5 million recorded during the nine months ended September 30, 2020, which did not occur during the same period in 2021.

The increase was primarily due to an increase in costs as a result of the launch of EYSUVIS, including expansion of Kala’s field sales force and stock-based compensation costs. Non-GAAP SG&A expenses were $70.1 million for the nine months ended September 30, 2021, compared to $47.2 million for the same period in 2020.
• R&D Expenses: For the nine months ended September 30, 2021, R&D expenses were $9.1 million, compared to $15.0 million for the same period in 2020. The decrease was primarily due to costs incurred for STRIDE 3, Kala’s Phase 3 clinical trial of EYSUVIS, during the nine months ended September 30, 2020, which were not incurred during the same period in 2021, partially offset by increased spending on pipeline programs. Non-GAAP R&D expenses were $6.1 million for the nine months ended September 30, 2021, compared to $12.5 million for the same period in 2020.
• Operating Loss: For the nine months ended September 30, 2021, loss from operations was $83.4 million, compared to $67.2 million for the same period in 2020.

Non-GAAP Financial Measures:
In this press release, the financial results of Kala are provided in accordance with accounting principles generally accepted in the United States (GAAP) and using certain non-GAAP financial measures. The items included in GAAP presentations but excluded for purposes of determining non-GAAP financial measures for the periods presented in this press release are stock-based compensation expense, loss on extinguishment of debt, non-cash interest expense and depreciation and amortization. Management believes this non-GAAP information is useful for investors, taken in conjunction with Kala’s GAAP financial statements, because it provides greater transparency and period-over-period comparability with respect to Kala’s operating performance. These measures are also used by management to assess the performance of the business. Investors should consider these non-GAAP measures only as a supplement to, not as a substitute for, or as superior to, measures of financial performance prepared in accordance with GAAP. In addition, these non-GAAP financial measures are unlikely to be comparable with non-GAAP information provided by other companies. For a reconciliation of these non-GAAP financial measures to the most comparable GAAP measures, please refer to the table at the end of this press release.

About EYSUVIS:
EYSUVIS (loteprednol etabonate ophthalmic suspension) 0.25% is approved for the short-term (up to two weeks) treatment of the signs and symptoms of dry eye disease. EYSUVIS utilizes Kala’s AMPPLIFY® mucus-penetrating particle (MPP) Drug Delivery Technology to enhance penetration of loteprednol etabonate (LE) into target tissue of the ocular surface. In preclinical studies, the AMPPLIFY Drug Delivery Technology increased delivery of LE into target ocular tissues more than three-fold compared to an active LE comparator by facilitating penetration through the tear film mucins. EYSUVIS was approved by the FDA on October 26, 2020. Kala believes that EYSUVIS’ broad mechanism of action, rapid onset of relief of both signs and symptoms, favorable tolerability and safety profile and the potential to be complementary to existing therapies, offer a differentiated product profile for the short-term treatment of dry eye disease, including the management of dry eye flares.

EYSUVIS, as with other ophthalmic corticosteroids, 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. The initial prescription and each 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 biomicroscopy, and, where appropriate, fluorescein staining. Prolonged use of corticosteroids may result in glaucoma with damage to the optic nerve, as well as defects in visual acuity and fields of vision. Corticosteroids should be used with caution in the presence of glaucoma. Renewal of the medication order should be made by a physician only after examination of the patient and evaluation of the IOP. Use of corticosteroids may result in posterior subcapsular cataract formation. Use of corticosteroids may suppress the host response and thus increase the hazard of secondary ocular infections. In acute purulent conditions, corticosteroids may mask infection or enhance existing infection. Use of a corticosteroid medication in the treatment of patients with a history of herpes simplex requires great caution. Use of ocular corticosteroids may prolong the course and may exacerbate the severity of many viral infections of the eye (including herpes simplex). Fungal infections of the cornea are particularly prone to develop coincidentally with long-term local corticosteroid application. Fungus invasion must be considered in any persistent corneal ulceration where a corticosteroid has been used or is in use. The most common adverse drug reaction following the use of EYSUVIS for two weeks was instillation site pain, which was reported in 5% of patients.

About INVELTYS:
INVELTYS (loteprednol etabonate ophthalmic suspension) 1% is a twice-a-day corticosteroid for the treatment of post-operative inflammation and pain following ocular surgery. INVELTYS utilizes Kala’s proprietary AMPPLIFY mucus-penetrating particle (MPP) Drug Delivery Technology to enhance penetration of loteprednol etabonate (LE) into target tissues of the eye. In preclinical studies, the AMPPLIFY Drug Delivery Technology increased delivery of LE into target ocular tissues more than three-fold compared to an active LE comparator by facilitating penetration through the tear film mucins. INVELTYS was approved by the FDA on August 22, 2018. Kala believes INVELTYS has a favorable profile for the treatment of inflammation and pain following ocular surgery, due to its twice-a-day dosing regimen.

INVELTYS, as with other ophthalmic corticosteroids, 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. A 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. Use of corticosteroids may result in posterior subcapsular cataract formation. 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 biomicroscopy and, where appropriate, fluorescein staining. 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. 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 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. In clinical trials, 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.
