ABECMA generated $72M U.S. commercial revenue in 2Q; continues to track toward upper end of $250-$300M revenue guidance for 2022

Results from prespecified interim analysis of KarMMa-3 trial shows ABECMA (idecabtagene vicleucel) significantly improves progression-free survival versus standard regimens in relapsed and refractory multiple myeloma

Ended quarter with $399M cash, cash equivalents, and marketable securities; revising 2022 net cash spend to $245-265M; maintaining cash runway into 2025

Conference call at 8:00 a.m. ET

2seventy bio, Inc. (Nasdaq: TSVT), a leading immuno-oncology cell therapy company, today reported financial results and recent highlights for the second quarter ended June 30, 2022.

“As 2seventy continues our first year as a new company, we remain on a solid growth trajectory with ongoing progress commercially with ABECMA and across our pipeline,” said Nick Leschly, chief kairos officer. “We were extremely pleased to announce this morning that the prespecified interim analysis of our KarMMa-3 Phase 3 study of ABECMA met the primary endpoint of progression-free survival with a safety profile that was consistent with prior studies. We look forward to sharing these results with regulators with the goal of treating multiple myeloma patients in earlier lines. We will share additional data from the KarMMa-3 study, our plans for future investment in ABECMA, and pipeline and portfolio updates throughout 2H22 as we continue our mission to develop innovative, un-incremental treatments for people living with cancer.”

ABECMA Commercial Summary and Business Update

Bristol Myers Squibb (BMS) reported total U.S. ABECMA (idecabtagene vicleucel; ide-cel) second quarter revenues of $72 million, representing 29% growth over the prior quarter. We continue to experience strong commercial demand and remain on track to achieve the upper end of our stated 2022 U.S. ABECMA revenue guidance of $250-300M. Given the continued strong demand and our growing belief in the potential for ABECMA to play an important role in earlier lines, we are continuing to advance our manufacturing strategy to expand capacity across the supply chain.

We reported share of collaboration loss of $4.3 million for the second quarter, which includes our share of gross profit/loss less costs associated with the commercialization of ABECMA in the U.S. In 2022, the collaboration experienced increased ABECMA manufacturing costs driven primarily by higher than anticipated vector costs. This has resulted in higher charges to 2seventy as part of our 50% share of U.S. costs with BMS. BMS is actively working with the vector manufacturer to lower costs and increase manufacturing capacity and 2seventy is supporting BMS in this work. Vector supply remains on track to meet our commercial plan for 2022 and we are continuing to invest in increasing manufacturing capacity in the future.

Given the increase in ABECMA costs that are shared by BMS with 2seventy, we are increasing our net cash spend guidance for 2022 to $245-265 million. All other spend for the rest of our business continues to track in line with previous guidance. We continue to forecast cash runway into 2025 based on current operating plans. This runway is sufficient to achieve important milestones across our business.

RECENT HIGHLIGHTS

• KARMMA-3 STUDY DELIVERS AT INTERIM: MET PRIMARY ENDPOINT - 2seventy, in partnership with BMS announced this morning positive topline results from the KarMMa-3 Phase 3 Study of ABECMA in adults with relapsed and refractory multiple myeloma who have had two to four prior lines of therapy and are refractory to the last regimen. This makes ABECMA the first B-cell maturation antigen (BCMA)-directed CAR T cell therapy to demonstrate superiority versus standard regimens in a randomized controlled trial. The study met its primary endpoint of demonstrating a statistically significant improvement in progression-free survival. Treatment with ABECMA also showed an improvement in the key secondary endpoint of overall response rate compared to standard regimens. Follow-up for overall survival, a key secondary endpoint, remains ongoing. Safety results were consistent with the well-established and predictable profile demonstrated in the pivotal KarMMa trial. The companies expect to present additional data from this study at a medical meeting in the future and discuss these findings with health authorities.
• ABECMA REAL-WORLD DATA AT ASCO – In June 2022, the largest data set to date for ABECMA patients treated in the commercial setting was presented at the 2022 American Society of Clinical Oncology (ASCO) Annual Meeting by the Multiple Myeloma Cell Therapy Consortium of academic institutions. The data presented were consistent with what was seen in the pivotal KarMMa study, reinforcing the efficacy and safety profile of ABECMA, even with 77% of the patients having comorbidities which would have rendered them too sick to participate in the KarMMa clinical trial.
• ADDITIONAL ASCO PRESENTATIONS – Additional updates from 2seventy bio’s portfolio of oncology cell therapies were presented at the meeting, including a correlative analysis, in partnership with BMS, defining patient profiles associated with manufacturing and clinical success in patients treated with ide-cel, a trial in progress poster on CRC-403, a phase 1/2 study on bbT369 in patients with relapsed and/or refractory B-NHL, and a trial in progress poster on PLAT-08, a phase 1 study of SC-DARIC-33 in relapsed or refractory pediatric and young adult acute myeloid leukemia (AML), presented by Seattle Children’s Therapeutics.

UPCOMING ANTICIPATED MILESTONES

• Anticipated $250-300 million total U.S. commercial revenue in 2022; profits and losses shared with BMS

• Increasing manufacturing capacity expected over 2022 and in the future
• KarMMa-2 study in high-risk multiple myeloma proof-of-concept data in 2022

SELECT SECOND QUARTER 2022 FINANCIAL RESULTS

• BMS reported total U.S. revenues of $72 million for ABECMA for the three months ended June 30, 2022. 2seventy bio and BMS share equally in all profits and losses related to development, manufacturing and commercializing ABECMA in the U.S. We reported share of collaboration loss of $4.3 million and $9.6 million for the three months and six months ended June 30, 2022, which includes our share of gross profit/loss less costs associated with the commercialization of ABECMA in the U.S. The collaboration reported a loss this quarter due to continued investment in manufacturing scale-up and commercialization.
• Total 2seventy revenues were $13.5 million for the three months ended June 30, 2022 compared to $7.3 million for the three months ended June 30, 2021. Total revenues were $21.9 million for the six months ended June 30, 2022 compared to $19.2 million for the six months ended June 30, 2021. The increase for the three- and six-month period was primarily driven by an increase in collaboration revenue during the second quarter of 2022, primarily attributable to an increase in collaboration-related activities with Regeneron.
• Research and development expenses were $68.4 million for the three months ended June 30, 2022 compared to $63.7 million for the three months ended June 30, 2021. Research and development expenses were $137.7 million for the six months ended June 30, 2022, compared to $141.3 for the six months ended June 30, 2021. The increase for the three-month period was primarily driven by an increase in material production costs and IT and other facility-related costs. The decrease for the six-month period was primarily driven by decreased collaboration research funding costs, which is primarily driven by a decrease in our share of research and development costs under our collaboration with BMS.
• Selling, general and administrative expenses were $17.3 million for the three months ended June 30, 2022, compared to $21.4 million for the three months ended June 30, 2021. Selling, general and administrative expenses were $41.1 million for the six months ended June 30, 2022, compared to $46.0 million for the six months ended June 30, 2021. The decrease for both the three- and six-month periods was primarily driven by decreased employee compensation expenses, reflective of efforts to streamline 2seventy’s operating model and a decrease in IT and other facility-related costs.
• Net loss was $77.4 million for the three months ended June 30, 2022, compared to $84.0 million for the three months ended June 30, 2021. Net loss was $163.1 million for the six months ended June 30, 2022, compared to $171.2 million for the six months ended June 30, 2021.

• 2seventy bio ended the second quarter of 2022 with cash, cash equivalents and marketable securities of $398.6 million.
