  • In the study of overweight and obese subjects, a placebo-adjusted weight loss of 6.3% was achieved at 6 weeks of treatment with 1.8 mg once weekly dose, surpassing the 2% pre-established treatment target
    
    
  • The multi-dose regimen was well-tolerated without the need for dose titration
  • No subject dropouts related to drug administration reported within the first 6 weeks of treatment
    
    
    
    
• Advancing to ALT-801 12-week data readout on three cohorts, expected in September 2021

Financial Results for the Three and Six Months Ended June 30, 2021

• Altimmune had cash, cash equivalents, short-term investments and restricted cash totaling $217.9 million at June 30, 2021 compared to $216.0 million at December 31, 2020. Through utilization of at-the-market (ATM) offerings during the second quarter of 2021, Altimmune raised net proceeds of $18.2 million and a total of $52.4 million since the beginning of the year.
• Revenue was $0.1 million for the three months ended June 30, 2021 compared to $0.7 million in the same period in 2020. The change in revenue quarter over quarter was primarily due to a decrease in BARDA revenue during the current period due to the timing of clinical trials and development activities for NasoShield.
• Research and development expenses were $13.3 million for the three months ended June 30, 2021, compared to $16.6 million in the same period in 2020. The change was primarily the result of increased expenses of $9.7 million primarily related to development activities for the Company’s COVID-19 programs, offset by a decrease of $13.0 million resulting from changes in the fair value of contingent consideration liability connected with the acquisition and development of ALT-801.
• General and administrative expenses were $3.7 million for the three months ended June 30, 2021 compared to $2.5 million in the same period in 2020. The increase during the quarter is primarily due to increased stock compensation expense and additional labor related costs.
• An impairment on construction-in-progress of $8.1 million was recognized for the three months ended June 30, 2021 related to the build out of a commercial scale manufacturing suite for the Company’s recently terminated COVID-19 vaccine program. No impairment was recognized in the prior year.
• Net loss for the three months ended June 30, 2021 was $24.8 million, or $0.60 net loss per share, compared to $16.8 million in the same period in 2020, or $0.94 net loss per share. Net loss for the six months ended June 30, 2021 was $39.7 million, or $0.99 net loss per share, compared to $20.7 million in the same period in 2020, or $1.25 net loss per share.
