Introduction
Eravacycline dihydrochloride, marketed under the brand name Xerava, is a novel antimicrobial drug developed to combat serious bacterial infections. This article delves into the market dynamics and financial trajectory of eravacycline, highlighting its development costs, market performance, and the broader context of the antimicrobial drugs market.
Development and Approval Costs
The development and approval of eravacycline dihydrochloride are associated with significant costs. According to the Antimicrobial Drugs Market Returns Analysis, the estimated development and approval cost for Xerava was approximately $182.7 million in 2018 dollars[4].
When considering the capitalized costs, which include the cost of failures and the opportunity cost of capital, the figure rises to $1,471.4 million in 2018 dollars. This is relatively lower compared to other drug cohorts, such as oncology drugs, which have much higher capitalized development and approval costs[1].
Clinical Value and Comparative Benefit
Eravacycline dihydrochloride has been evaluated for its clinical value using various metrics, including the Overall Clinical Value Score. With European Health Technology Assessment (HTA) scores, Xerava's clinical value score is 209, and without HTA scores, it is 146. These scores indicate the drug's comparative added clinical benefit relative to other treatments for similar indications[4].
Market Performance
The market performance of Xerava is measured by its cumulative global sales since its market launch. According to the IQVIA MIDAS data, the first nine quarters of sales for Xerava amounted to $12.79 million in 2018 dollars. This figure is modest compared to the sales of oncology drugs but aligns with the general trend that antimicrobial drugs tend to have lower sales volumes due to their conservative use to prevent resistance[1][4].
Sales vs. Clinical Benefit
There is a correlation between the comparative added clinical benefit of a drug and its early market sales. Drugs with higher clinical benefit scores tend to have higher sales, although this relationship is more pronounced in the oncology cohort. For antimicrobial drugs like Xerava, the sales are significantly lower but still reflect the drug's clinical value[1].
Market Dynamics of Antimicrobial Drugs
The antimicrobial drugs market is characterized by growing demand, particularly in low- and middle-income countries (LMICs), but it is also marked by low profit margins and high development risks. The market is expected to grow to $55.8 billion by 2023, up from $38.3 billion in 2018, driven by increasing generic antibacterial demand[3].
However, the development of new antimicrobials is challenging due to the evolutionary arms race between pathogens and medicines, leading to resistance. This has resulted in a drying up of the global antibacterial pipeline, with only 15 new antibacterials approved since 2000, compared to 63 between 1980 and 2000[3].
Incentives for Antimicrobial R&D
To incentivize the development of new antimicrobial medicines, various "push" and "pull" mechanisms have been implemented. Push incentives include research grants, tax incentives, and public-private partnerships, while pull mechanisms involve guarantees of revenue through extended market exclusivity, accelerated regulatory pathways, or premium pricing. For example, the Generating Antibiotic Incentives Now (GAIN) Act in the United States grants an additional five years of market exclusivity to companies developing new antibacterials[3].
Regulatory Environment
The regulatory environment plays a crucial role in the market dynamics of antimicrobial drugs. The FDA's guidance and approval processes are critical for bringing new drugs like Xerava to the market. The FDA's current thinking on eravacycline dihydrochloride is outlined in their draft guidance, which reflects the agency's approach to ensuring the safety and efficacy of antimicrobial treatments[5].
Competitive Landscape
The competitive landscape for antimicrobial drugs is complex, with both large pharmaceutical companies and smaller biopharmaceutical firms involved. While some large companies have reduced their involvement in antimicrobial R&D due to low profit margins, a core group of companies remains committed to this area. Smaller biopharmaceutical companies are also increasingly focused on antimicrobial R&D, driven by the urgent need for new treatments[3].
Future Outlook
The future outlook for eravacycline dihydrochloride and other antimicrobial drugs is influenced by the ongoing battle against antimicrobial resistance (AMR). The need for new products is urgent, and the market is expected to continue growing, albeit with challenges related to resistance and low profit margins. Incentives and regulatory support will be crucial in sustaining R&D efforts in this critical therapeutic area.
