Blackstone Life Sciences (BXLS)

1. Medicines brought to market by BXLS and development company employees and advisors (Nick Galakatos, Paris Panayiotopoulos, Kurt Wheeler, Barry Gertz, Dennis Henner, Ed Scolnick, Kiran Reddy, Francois Nader, Olivier Brandicourt, John Maraganore, Peter Honig, Elaine Caughey and Allison Jeynes) while they worked at BXLS, Clarus and at prior employers. The development of a medicine involves many professionals. The degree of involvement by a given BXLS, advisor, or development company professional varies medicine to medicine. Therefore, the performance shown reflects the contributions of a number of professionals and may not be indicative of any individual’s contributions to the transactions. The number of developed medicines is measured when a drug is approved in any jurisdiction.

2. As of September 30, 2024. Based on Phase III drug developments analyzed between 2010–2024. In deriving the Phase III success rate, Blackstone uses the same methodology as Evaluate Pharma, neither of which methodology incorporates data relating to approval for MedTech products. In determining the success rate, both Blackstone and Evaluate Pharma consider a drug’s approval by the US FDA or the EMA to each count as a separate, independent approval and a drug’s approval in each new indication to also be considered an approval when calculating the success rate. This methodology will result in a higher success rate than would otherwise result if only one of the aforementioned types of approval were used when calculating the success rate. For purposes of calculating the success rate, Blackstone does not include any Phase III trials that were never initiated. A trial is considered “initiated” when the first patient is enrolled in a clinical trial. For the avoidance of doubt, Blackstone considers suspended, abandoned, or never completed trials as “failures” when determining the success rate. Whereas Evaluate Pharma’s review period is as of January 1, 2000- May 31, 2018, BXLS’ review period is from 2010 to 2024, which coincides with the period beginning when BXLS, through a predecessor fund, made its first investment in a Phase III drug trial. Evaluate Pharma’s data represents their most recently available data. There are risks and limitations to comparing BXLS’ shortened period of review to Evaluate Pharma’s longer and different period because market conditions, including among others macroeconomic factors and regulatory and policy considerations, as well as other factors beyond BXLS’ control, change regularly and could adversely impact the likelihood of approval, thereby negatively impacting the industry’s and BXLS’ success rates in a given time period. These and numerous other factors may adversely affect the success rates, and thus success rates in one time period are not directly comparable to success rates of drugs evaluated in different time periods.
