Plazomicin’s Failure to Commercialise: A Deep Dive into Financial Analysis and Lessons for the Antibiotic Investment Ecosystem

Plazomicin, a new antibiotic developed by Achaogen Inc., was once hailed as a potential game-changer in the fight against multi-drug resistant bacteria. However, in September 2019, Achaogen announced that it was discontinuing the commercialisation efforts for Plazomicin due to financial reasons. This unexpected development raised significant concerns and sparked a debate within the antibiotic investment ecosystem. In this analysis, we will delve deep into Plazomicin’s financial performance, identify key contributing factors to its failure, and discuss the broader implications for the antibiotic investment ecosystem.

Financial Performance of Plazomicin

Plazomicin received FDA approval in January 2018 for the treatment of complex urinary tract infections (cUTI) caused by specific Gram-negative bacteria. Despite this milestone, Plazomicin’s financial performance did not meet expectations. According to Achaogen’s Q3 2019 earnings report, the company recorded a net loss of $161.5 million for the first nine months of 2019, compared to a net loss of $84.9 million during the same period in 2018. The primary reason for this significant increase in losses was the higher operating expenses related to commercialisation efforts.

Commercialisation Efforts and Market Competition

Achaogen’s decision to discontinue commercialisation efforts for Plazomicin was influenced by several factors. First, the antibiotic market is highly competitive and crowded with established players like Merck & Co.’s Recarbrio and Pfizer’s Zavicefta.

Consequently, it became increasingly challenging for Achaogen to secure a substantial market share for Plazomicin.

Reimbursement and Pricing Challenges

Additionally, Plazomicin faced significant challenges related to reimbursement and pricing. In the US, Medicare’s Administration Competitive Bidding Program (ACB) established a payment rate for Plazomicin that was much lower than what Achaogen anticipated. This pricing pressure made it difficult for the company to recoup its investment and generate profitability. Moreover, Plazomicin’s high cost compared to other available treatment options further limited its market penetration.

Lessons for the Antibiotic Investment Ecosystem

Plazomicin’s failure to commercialise provides valuable lessons for the antibiotic investment ecosystem. First, it highlights the importance of conducting thorough market analysis and identifying competitive differentiation before investing in a new antibiotic. Second, it underscores the need to consider reimbursement and pricing challenges that can significantly impact market penetration and profitability. Lastly, it emphasizes the importance of collaboration between industry, regulatory agencies, and payers to develop sustainable antibiotic pricing models that incentivise innovation while maintaining affordability for patients.
