We look forward to sharing more insights on our clinical and preclinical pipeline and our commercial launch efforts at our investor day in November.”

THIRD QUARTER 2021 FINANCIAL RESULTS

The financial results discussion compares Agios’ continuing operations. All periods have been adjusted to exclude discontinued operations related to the divested oncology business.

The year-over-year increase in R&D was driven primarily by start-up costs associated with the Phase 3 studies of mitapivat in thalassemia and sickle cell disease, as well as disease education and engagement efforts for mitapivat in PK deficiency, thalassemia and sickle cell disease.

Selling, General and Administrative (SG&A) Expenses: SG&A expenses for continuing operations were $27.2 million for the third quarter of 2021 compared to $28.3 million for the third quarter of 2020.

Non-Operating Income: Non-operating income included approximately $2.0 million from TIBSOVO^® (ivosidenib) royalties for the third quarter of 2021.

Net Loss: Net loss was $88.8 million for the third quarter of 2021 compared to a net loss of $99.0 million for the third quarter of 2020.

Cash Position and Guidance: Cash, cash equivalents and marketable securities as of Sept. 30, 2021, were $1.4 billion compared to $722.4 million as of Sept. 30, 2020. The company expects that its cash, cash equivalents and marketable securities will enable the company to execute its operating plan through major catalysts and to cash-flow positivity without the need to raise additional equity.
