"During the first quarter, we advanced our portfolio of innovative ADCs and accelerated preparations for two potential product launches next year," said Mark Enyedy, ImmunoGen’s President and Chief Executive Officer. "We saw a limited delay in patient enrollment in the pivotal SORAYA trial for our lead program, mirvetuximab soravtansine, which has shifted the anticipated timing of top-line data from the third into the fourth quarter of this year and the projected submission of the BLA into the first quarter of 2022. We have also experienced some COVID-related impact on accrual to our confirmatory MIRASOL trial and now expect the read-out on the primary endpoint to move from the second into the third quarter of 2022. Beyond SORAYA and MIRASOL, we are commencing several studies to move mirvetuximab into earlier lines of ovarian cancer therapy, including an investigator-sponsored trial of mirvetuximab in combination with carboplatin in the neoadjuvant setting that initiated this quarter. We are also supporting a randomized study comparing mirvetuximab combined with carboplatin to standard of care in patients with recurrent platinum-sensitive disease and have submitted a protocol to FDA for a single-arm study of mirvetuximab monotherapy in later-line platinum-sensitive patients, with both studies anticipated to begin enrollment in the second half of this year. Finally, we were pleased to receive notice that mature data from our mirvetuximab plus Avastin doublet cohort in recurrent ovarian cancer, regardless of platinum status, have been selected for an oral presentation at ASCO (Free ASCO Whitepaper) in June."
Enyedy added, "We continued enrollment for our second pivotal program, IMGN632, in patients with frontline and relapsed/refractory BPDCN, with top-line data expected in the first half of 2022. IMGN632 is also in ongoing development in AML, both as a monotherapy and in combinations. Moving to our earlier-stage portfolio, we presented preclinical data at AACR (Free AACR Whitepaper) last month on IMGC936, our first-in-class ADAM9-targeting ADC, demonstrating anti-tumor activity in multiple solid tumor models, and we advanced dose escalation in the Phase 1 study for this program. IND-enabling activities for our next-generation anti-FRα ADC, IMGN151, are on track to submit an application to the FDA by the end of 2021. With pre-commercial activities underway, we look forward to a meaningful year ahead with a number of important milestones across the business as we work towards bringing our first two therapies to market next year."

FINANCIAL RESULTS
Revenues for the quarter ended March 31, 2021 were $15.7 million, compared with $13.3 million for the quarter ended March 31, 2020, which consisted primarily of non-cash royalty revenues.
Operating expenses for the first quarter of 2021 were $44.6 million, compared with $37.1 million for the same quarter in 2020. The increase was largely driven by research and development expenses, which were $34.4 million in the first quarter of 2021, compared with $27.4 million for the first quarter of 2020. This increase was primarily due to greater clinical trial expenses driven by costs related to the MIRASOL, SORAYA, and IMGC936 studies, greater external manufacturing costs, and greater personnel and temporary staffing costs. General and administrative expenses for the first quarter of 2021 increased to $10.2 million, compared to $8.9 million for the first quarter of 2020, primarily due to increased professional fees and personnel costs, including greater stock-based compensation. Operating expenses for the first quarter of 2020 included a $0.8 million restructuring charge related to retention costs.
Net loss for the first quarter of 2021 was $34.1 million, or $0.17 per basic and diluted share, compared to a net loss of $29.1 million, or $0.17 per basic and diluted share, for the first quarter of 2020. Weighted average shares outstanding increased to 198.8 million for the 2021 period from 166.9 million in the prior year.
ImmunoGen had $283.1 million in cash and cash equivalents as of March 31, 2021, compared with $293.9 million as of December 31, 2020, and had $2.1 million of convertible debt outstanding in each period. Cash used in operations was $44.6 million for the first three months of 2021, compared with cash used in operations of $28.3 million for the same period in 2020. Capital expenditures were $(0.9) million for the first quarter of 2021, compared with net proceeds from the sale of equipment of $1.4 million for the first quarter of 2020.
FINANCIAL GUIDANCE
ImmunoGen’s financial guidance for 2021 remains unchanged:
revenues between $65 million and $75 million;
operating expenses between $200 million and $210 million; and
cash and cash equivalents at December 31, 2021 to be between $140 million and $150 million.
ImmunoGen expects that its current cash will fund operations into the second half of 2022.
