CONSENSI Market Analysis and Financial Projection Experimental

Market Dynamics and Financial Trajectory for the Drug: Consensi

Introduction

Consensi, a combination drug of amlodipine and celecoxib, was approved by the FDA on May 31, 2018, for the treatment of hypertension and pain associated with osteoarthritis. Despite its innovative formulation, the drug's market performance and financial trajectory have been marked by significant challenges.

FDA Approval and Initial Market Entry

Consensi was developed by Kitov Pharmaceuticals, later known as Purple Biotech Ltd., and represented a unique combination of a calcium channel blocker (amlodipine) and a nonsteroidal anti-inflammatory drug (celecoxib)[1].

Commercialization Challenges

From the outset, Consensi faced substantial commercialization hurdles. The drug's entry into the market was anticipated to be competitive, given the established presence of both amlodipine and celecoxib as standalone treatments.

Termination of Distribution Agreement

A critical turning point came on February 9, 2022, when Purple Biotech Ltd. announced the termination of the agreement with the U.S. distributor for Consensi. This decision was driven by the conclusion that commercialization of Consensi was unlikely to generate significant revenue or achieve profitability in the near term[1].

Discontinuation of Consensi

As a result of the financial projections, Purple Biotech Ltd. decided to discontinue Consensi to reduce the expenses associated with maintaining the product. The marketing end date for Consensi was set for July 27, 2022[1].

Revenue and Profitability Issues

The failure of Consensi to achieve profitability highlights broader issues within the pharmaceutical industry. For branded prescription drugs, manufacturers typically capture a significant portion of the revenue, with approximately $76 out of every $100 spent going to the manufacturers. However, this does not necessarily translate to profitability for every drug, especially those with limited market demand or intense competition[2].

Market Concentration and Pricing

The pharmaceutical supply chain is highly concentrated, with top players dominating significant market shares. This concentration can lead to higher consumer prices and complex pricing dynamics. For Consensi, navigating this landscape proved challenging, particularly in a market where generic alternatives and established brand names already held strong positions[2].

Economic Implications of Drug Development

The development and pricing of pharmaceuticals are influenced by various economic factors, including the cost of research and development (R&D), the size of the target patient population, and the presence of government incentives. For Consensi, the combination of amlodipine and celecoxib did not generate enough value to justify the R&D investments and ongoing costs associated with its maintenance[3].

Role of Pharmacy Benefit Managers (PBMs) and Insurers

Pharmacy benefit managers and insurers play a crucial role in the pharmaceutical supply chain, negotiating prices and influencing the profitability of drugs. However, their large market power can sometimes result in higher profits for these intermediaries rather than lower prices for consumers. In the case of Consensi, the lack of favorable negotiations with PBMs and insurers may have further exacerbated its commercial challenges[2].

Consumer Impact

The discontinuation of Consensi affects patients who were relying on this specific combination therapy for their hypertension and osteoarthritis. This highlights the broader issue of drug accessibility and affordability, where patients often bear the brunt of market dynamics and financial decisions made by pharmaceutical companies.

Lessons Learned

The story of Consensi serves as a cautionary tale for pharmaceutical companies. It underscores the importance of thorough market analysis, robust financial planning, and strategic partnerships in the highly competitive and regulated pharmaceutical industry.

Future Outlook

For drugs like Consensi, the future hinges on the ability to demonstrate significant clinical value and economic viability. This involves not only meeting regulatory requirements but also navigating the complex web of market forces, including pricing negotiations and supply chain dynamics.

Key Takeaways

• Commercialization Challenges: Consensi faced significant commercialization hurdles, leading to its discontinuation.
• Financial Projections: The drug was not expected to generate significant revenue or achieve profitability.
• Market Concentration: The pharmaceutical supply chain is highly concentrated, affecting pricing and profitability.
• Economic Factors: R&D costs, patient population size, and government incentives influence drug development and pricing.
• Role of PBMs and Insurers: These intermediaries play a crucial role in negotiating prices and influencing drug profitability.
