TRIESENCE Market Analysis and Financial Projection Experimental

Market Dynamics and Financial Trajectory for TRIESENCE

Introduction

TRIESENCE, a preservative-free synthetic corticosteroid developed by Novartis and now under the umbrella of Harrow Health, has been a crucial product in the ophthalmic pharmaceutical market. After a significant period of shortage, Harrow is relaunching TRIESENCE, marking a pivotal moment for both the company and the healthcare industry.

Historical Context and Acquisition

In January 2023, Harrow acquired the exclusive U.S. rights to five FDA-approved branded ophthalmic products from Novartis, including TRIESENCE, for $130 million plus an additional $45 million contingent on the commercial launch of TRIESENCE[3][4].

Product Indications and Importance

TRIESENCE (triamcinolone acetonide injectable suspension) 40 mg/mL is indicated for visualization during vitrectomy and the treatment of ocular inflammatory conditions unresponsive to topical corticosteroids. It is also used for conditions such as sympathetic ophthalmia, temporal arteritis, and uveitis. The product's preservative-free formulation reduces the risk of adverse reactions, making it a trusted and effective treatment option in ophthalmology[1][3][4].

Manufacturing and Supply Chain Challenges

TRIESENCE has been on the FDA Drug Shortage List for over five years due to manufacturing delays and supply chain issues. This shortage resulted in no inventory available in the U.S. market for over two years, creating a significant demand vacuum[1][3].

Relaunch and Manufacturing Updates

Harrow has successfully manufactured the first of three commercial-scale process performance qualification (PPQ) batches of TRIESENCE. The remaining two PPQ batches are scheduled, and if all batches meet specifications, TRIESENCE is set to relaunch in 2024. Harrow is committed to quickly building commercial inventories, although initial supplies may not fully meet market demand[1].

Market Readiness and Pre-Commercial Activities

Harrow has initiated pre-commercial activities, including discussions with strategic accounts for pre-orders. This proactive approach aims to ensure market readiness and smooth distribution once the product is relaunched[1][4].

Financial Impact and Revenue Potential

The relaunch of TRIESENCE is expected to have a significant financial impact on Harrow. The company has seen a 33% increase in revenues in the first quarter of 2024 compared to the prior year, partly due to the anticipation of TRIESENCE's return. Harrow expects to meet its 2024 revenue guidance of more than $180 million, with TRIESENCE contributing substantially to this growth[2].

Revenue Growth and Projections

Harrow's financial results for the first quarter of 2024 show net revenues of $34.6 million, a notable increase from the $26.1 million in the prior-year quarter. The company's gross margin and core gross margin remain strong, indicating a robust financial foundation for the relaunch of TRIESENCE[2].

Operational Expenses and Long-Term Potential

While the short-term operational expenses are expected to increase due to the manufacturing and pre-commercial activities, the long-term revenue potential of TRIESENCE is substantial. Investors are advised to monitor the completion of the remaining PPQ batches and initial sales figures to gauge the success of the relaunch[1][2].

Market Acceptance and Demand

The pent-up demand for TRIESENCE, given its absence for over two years, presents a unique opportunity for Harrow to regain market share quickly. Ophthalmologists and retina specialists have been eagerly awaiting the product's return, which is expected to improve patient outcomes significantly[1][3].

Competitive Landscape

Harrow's acquisition of TRIESENCE and other ophthalmic products from Novartis has positioned the company as a leader in the U.S. ophthalmic pharmaceutical market. The successful relaunch of TRIESENCE will further solidify Harrow's market position and complement its existing portfolio of ophthalmic prescription products[3][4].

Regulatory and Compliance Aspects

The transfer of the New Drug Application (NDA) for TRIESENCE from Novartis to Harrow was completed ahead of schedule, which was a critical step in advancing the product's relaunch strategy. This transfer ensured that Harrow could implement its market access, marketing, and inventory management strategies effectively[4].

• Market Readiness: Pre-commercial activities are underway to ensure smooth distribution and market readiness.
