Explanation of Responses:

1. On May 8, 2024, certain private investment vehicles managed by Redmile Group, LLC ("Redmile"), including RedCo II Master Fund, L.P. ("RedCo II" and collectively with the other private investment vehicles managed by Redmile, the "Redmile Clients"), acquired, in an underwritten public offering, pre-funded warrants (the "Pre-Funded Warrants") to purchase Common Shares of the Issuer (the "Pre-Funded Warrant Shares") at a purchase price per Pre-Funded Warrant equal to $4.812.

2. The exercise price of the Pre-Funded Warrants is CHF 0.08 per Pre-Funded Warrant Share. Based on the May 8, 2024 exchange rate of $1.1013 USD to CHF 1.00, the exercise price of the Pre-Funded Warrants in US Dollars as of May 8, 2024 is approximately $0.088.

3. The Pre-Funded Warrants are exercisable by the holder at any time after their original issuance until the tenth anniversary of their original issuance, subject to a 9.99% beneficial ownership blocker. At any time during the last 90 days of the term of the Pre-Funded Warrants, the holder thereof may exchange a Pre Funded Warrant with the Issuer for a new Pre Funded Warrant to purchase the number of Pre-Funded Warrant Shares then remaining under such Pre-Funded Warrant, with a subsequent ten-year exercise period.
