AN2 Therapeutics Provides Update on EBO-301 Phase 2/3 Study Evaluating Epetraborole for Treatment-Refractory Mycobacterium avium Complex (MAC) Lung Disease
AN2 Therapeutics (Nasdaq: ANTX) announced that the EBO-301 Phase 2/3 study evaluating epetraborole for treatment-refractory Mycobacterium avium Complex (MAC) lung disease will be discontinued. The Phase 2 part met its primary objective of demonstrating a higher patient-reported outcome (PRO)-based clinical response rate (39.5% vs. placebo 25.0%; p=0.19), but sputum culture conversion at Month 6 was similar between treatment arms (13.2% vs. 10.0%; p=0.64). No significant safety concerns were noted.
The company will shift focus to its boron chemistry platform and other pipeline programs, including Chagas disease and melioidosis. Restructuring and cost savings are expected to extend the cash runway through 2027. Further evaluation of the EBO-301 study results will inform future development of epetraborole for NTM lung disease.
AN2 Therapeutics (Nasdaq: ANTX) ha annunciato che lo studio EBO-301 di Fase 2/3 che valuta epetraborole per la malattia polmonare da Mycobacterium avium complesso (MAC) resistente al trattamento sarà interrotto. La parte di Fase 2 ha raggiunto il suo obiettivo principale dimostrando un tasso di risposta clinica basato su risultati riferiti dai pazienti (PRO) più elevato (39.5% rispetto al placebo 25.0%; p=0.19), ma la conversione della coltura di espettorato al mese 6 è stata simile tra i gruppi di trattamento (13.2% rispetto al 10.0%; p=0.64). Non sono state rilevate preoccupazioni significative per la sicurezza.
L'azienda si concentrerà sulla sua piattaforma di chimica del boro e su altri programmi in pipeline, inclusi la malattia di Chagas e la melioidosi. Si prevede che il ristrutturazione e il risparmio sui costi estenderanno la liquidità fino al 2027. Ulteriori valutazioni dei risultati dello studio EBO-301 informeranno lo sviluppo futuro di epetraborole per la malattia polmonare NTM.

AN2 Therapeutics (Nasdaq: ANTX) hat angekündigt, dass die EBO-301 Phase 2/3 Studie, die epetraborole zur Behandlung der behandlungsresistenten Mycobacterium avium Komplex (MAC) Lungenerkrankung bewertet, eingestellt wird. Der Teil der Phase 2 hat sein Hauptziel erreicht, eine höhere klinische Antwortquote, die auf Patientenergebnissen (PRO) beruht, zu demonstrieren (39,5 % gegenüber Placebo 25,0 %; p=0,19), jedoch war die Umstellung der Sputumkultur im Monat 6 zwischen den Behandlungsgruppen ähnlich (13,2 % gegenüber 10,0 %; p=0,64). Es wurden keine signifikanten Sicherheitsbedenken festgestellt.
Das Unternehmen wird seinen Fokus auf seine Borchemie-Plattform und andere Pipeline-Programme, einschließlich der Chagas-Krankheit und Melioidose, verlagern. Durch Umstrukturierungen und Kosteneinsparungen wird eine Liquidität bis 2027 erwartet. Eine weitere Bewertung der Ergebnisse der EBO-301 Studie wird die zukünftige Entwicklung von epetraborole für NTM Lungenerkrankungen beeinflussen.
- Phase 2 met primary objective with higher PRO-based clinical response rate.
- Epetraborole was generally well-tolerated with no significant safety concerns.
- Restructuring expected to extend cash runway through 2027.
- Focus on promising boron chemistry platform and pipeline programs in infectious diseases and oncology.
- EBO-301 study discontinued due to similar sputum culture conversion rates between treatment arms.
- Potentially lower-than-expected efficacy observed in Phase 3 led to pause in new patient enrollment.
The discontinuation of the EBO-301 Phase 2/3 study for epetraborole in treatment-refractory MAC lung disease is a significant setback for AN2 Therapeutics. While the study met its primary objective of demonstrating a higher PRO-based clinical response rate (
The company's pivot to focus on its boron chemistry platform and other pipeline programs is a strategic move to salvage value from this setback. The planned initiation of clinical trials for Chagas disease and melioidosis represents potential new avenues for growth, albeit in different therapeutic areas. This diversification strategy could help mitigate risks associated with single-product dependency.
The discontinuation of the EBO-301 study is likely to have a negative impact on AN2 Therapeutics' short-term prospects. However, the company's proactive approach to restructuring and cost-saving measures is a positive sign. By extending their cash runway through 2027, AN2 is buying time to develop its pipeline and potentially reach multiple milestones.
Investors should note the shift in focus to the company's boron chemistry platform and other programs. This diversification could reduce risk but also introduces uncertainty about future revenue streams. The company's ability to advance its pipeline, particularly in Chagas disease and melioidosis, will be crucial for its long-term value proposition. The continuation of non-dilutive funding for global health initiatives is a positive factor, potentially offsetting some R&D costs.
The failure of epetraborole in treatment-refractory MAC lung disease highlights the challenges in developing therapies for complex respiratory infections. However, AN2 Therapeutics' focus on boron chemistry remains intriguing. Boron's unique binding properties offer potential advantages in drug development, particularly for targets that have been difficult to address with traditional carbon-based molecules.
The company's pivot to Chagas disease and melioidosis represents a strategic shift towards neglected tropical diseases and biodefense. These areas often have less competition and potential for government support. The planned Phase 2 study in melioidosis, aiming to reduce the high mortality rate, could be particularly impactful if successful. Investors should watch for progress in these new indications and any emerging data from the company's early-stage oncology programs, which could provide new growth opportunities.
EBO-301 study to be discontinued following topline results from Phase 2 part of the study in treatment-refractory patients with MAC lung disease
AN2 plans to shift focus to internal boron chemistry platform and ongoing pipeline programs
Company restructuring and cost savings associated with discontinuation of the EBO-301 study expected to extend cash runway through 2027
The Phase 2 part of the study met its primary objective of demonstrating the potential validation of a novel patient-reported outcome (PRO) tool and a higher PRO-based clinical response rate in the epetraborole + OBR arm (
In February, the Company voluntarily paused new patient enrollment in the Phase 3 part of the study due to potentially lower-than-expected efficacy observed in blinded aggregate data. Based on the topline data announced today, the Company will terminate the Phase 2 (80 patients) and Phase 3 parts of the EBO-301 trial (97 patients enrolled prior to pause). Oral epetraborole 500 mg daily was generally well-tolerated and the study was not terminated due to safety concerns.
“These results are deeply disappointing as there is a high unmet need for new therapies in treatment-refractory MAC lung disease,” said Eric Easom, Co-founder, Chairman, President and CEO. “We sincerely thank the patients, investigators, study site staff and AN2 employees who were part of the journey to investigate the prospects of epetraborole in this very difficult-to-treat patient population.”
“In the coming months, we will further evaluate the results from the EBO-301 study and make informed decisions regarding potential future development of epetraborole for NTM lung disease in other patient populations. In the near-term, we plan to accelerate our R&D efforts on our boron chemistry platform where we believe we have several promising programs in infectious diseases and oncology. We plan to embark on a strategic restructuring and expect to extend our cash runway through 2027, focusing our cash resources on advancing our pipeline through multiple milestones,” said Easom.
AN2’s core technology approach is based on the use of boron chemistry for its research and development initiatives. Boron has a distinctive ability to bind with biological targets through a reversible covalent bond and the potential to address biological targets that have been difficult to inhibit using traditional carbon-based molecules.
