Market Dynamics and Financial Trajectory for the Drug: Seromycin (Cycloserine)
Introduction
Seromycin, known chemically as cycloserine, is an antibiotic used to treat multi-drug resistant tuberculosis (MDR TB), a rare and life-threatening form of tuberculosis. Developed in 1955, it has been a crucial component in the treatment regimen for MDR TB. Here, we delve into the market dynamics and financial trajectory of this essential medicine.
Historical Context and Development
Cycloserine was first approved by the FDA in 1964 and was initially owned by Eli Lilly and Co.[4].
It has been sold under the trade name Seromycin since its approval, making it one of the older drugs still in use today.
Ownership and Supply Chain
The rights to cycloserine have changed hands several times. As of recent years, the ownership is held by Purdue GMP Center Inc.[4].
Prior to this, The Chao Center, part of the Purdue Research Foundation, was involved in its production and distribution, particularly focusing on ensuring its availability for patients who could not afford it[1].
Pricing Controversies
One of the most significant events in the financial trajectory of cycloserine was the attempted price hike by Rodelis Therapeutics in 2015. Rodelis acquired the rights to cycloserine from The Chao Center with plans to increase the price from $480 to $10,800 for a 30-pill prescription. This move was met with widespread outrage and was eventually reversed after The Chao Center requested the rights back, citing that the price increase was not in line with their intentions[1][4].
Current Pricing and Accessibility
Following the reversal, The Chao Center decided to raise the price of cycloserine but to a much more moderate level, from $480 to about $1,050 per bottle. This increase was aimed at sustaining the production costs and ensuring the drug's continued availability[1].
Despite being available since 1964, the accessibility of cycloserine remains a concern due to its high cost. The question remains whether a medicine is truly accessible if it is unaffordable for many patients[4].
Market Fragmentation and Demand
The market for second-line drugs (SLDs) like cycloserine, used in treating MDR TB, is highly fragmented. This fragmentation is exacerbated by country-to-country variations in treatment regimens and the introduction of new drugs. Achieving market stability and reliable forecasting is challenging due to these factors[3].
Financing and Funding Challenges
The financing of MDR TB treatment, including drugs like cycloserine, is complex. Only about 39% of available funds are actually used by countries for MDR TB treatment regimens, leading to an unpredictable market for manufacturers and donors. This situation makes it difficult to ensure a stable and uninterrupted supply of the drug[3].
Role of Global Funders
Key funders such as the Global Fund, UNITAID, and individual governments play a crucial role in the MDR TB market. There is a need for these stakeholders to cooperate more effectively to stimulate price competition and ensure predictable and timely treatment delivery. Innovative financing initiatives, such as those employed by GAVI, aim to improve predictability and flexibility of funding, ensuring sufficient and uninterrupted drug supply[3].
Impact of New Drugs and Technologies
The introduction of new drugs and diagnostic technologies, such as GeneXpert, can significantly impact the market dynamics. These innovations can help determine the actual need for drugs like cycloserine more accurately and improve market certainty. However, they also introduce new challenges in forecasting and managing the market[3].
Clinical Use and Efficacy
Beyond its use in MDR TB, cycloserine has been explored for other clinical applications. For instance, it has shown promise as an adjunctive treatment in psychiatric conditions when combined with transcranial magnetic stimulation (TMS). Clinical trials have indicated that cycloserine can enhance the efficacy of TMS in treating depression[5].
Regulatory and Production Costs
The Chao Center, which previously managed the production of cycloserine, reported significant losses due to the high costs of complying with regulatory requirements. This financial strain is a common challenge for producers of rare and orphan drugs, highlighting the need for sustainable funding models to support their production[1].
Public and Political Response
The attempted price hike of cycloserine in 2015 drew significant public and political attention. Presidential candidates and other public figures weighed in on the issue, highlighting the broader problem of price gouging in the specialty drug market. This public outcry underscores the need for transparent and fair pricing practices in the pharmaceutical industry[1].
Key Takeaways
