"Building on the momentum generated in the first half of 2023, we delivered a strong third quarter highlighted by significant ELAHERE revenue growth and the achievement of key operational milestones," said Mark Enyedy, ImmunoGen’s President and Chief Executive Officer. "With a 36% increase in sequential quarterly net sales and over $210 million in product revenue through the first nine months of the year, ELAHERE is tracking towards one of the most successful first product launches in oncology in a decade. We also made important progress in our effort to bring ELAHERE to eligible patients around the world with the acceptance of the MAA by the EMA and the NDA by the NMPA, and the establishment of a collaboration with Takeda to deliver ELAHERE in Japan."
Enyedy continued, "In addition, we advanced the ELAHERE development program and are pleased to report that our PICCOLO trial in platinum-sensitive ovarian cancer has met the primary endpoint of objective response rate based on an interim efficacy assessment. With a number of patients remaining on treatment and longer follow-up required to establish mature response durability of ELAHERE in this patient population, we anticipate an ORR of at least 48% when we report full data in mid-2024. Turning to our second pivotal program, PVEK, we continue to advance our 802 study and look forward to reporting data from our PVEK/VEN/AZA triplet in frontline AML at ASH (Free ASH Whitepaper) in December. We also continued to monitor the NSCLC cohort with IMGC936 and advanced dose escalation with IMGN151, our second-generation ADC targeting FRα. We look forward to a strong finish to the year and a productive 2024 with the continued growth of ELAHERE, important new data for our programs, and geographic expansion in Europe and China."
RECENT PROGRESS
ELAHERE (mirvetuximab soravtansine-gynx)
Generated $105.2 million in ELAHERE net sales for the quarter ended September 30, 2023.
Obtained acceptance of the Marketing Authorization Application (MAA) by the European Medicines Agency (EMA) for ELAHERE in folate receptor alpha (FRα)-positive platinum-resistant ovarian cancer (PROC) to support approval and launch in Europe.
Submitted the supplemental Biologics License Application (sBLA) to the US Food and Drug Administration (FDA) to support conversion to full approval.
Our partner, Huadong Medicine, obtained acceptance of the New Drug Application (NDA) to the National Medical Products Administration (NMPA) of China for ELAHERE in FRα-positive PROC to support approval and launch.

Clinical Pipeline and Research
Presented additional subset analyses in prior lines of therapy and prior exposure to PARP inhibitor (PARPi) therapy from MIRASOL in an oral session at the 24th Congress of the European Society of Gynaecological Oncology (ESGO) demonstrating clinical outcomes of safety and efficacy consistent with the overall MIRASOL study population.
Reported that PICCOLO, the ongoing single-arm Phase 2 trial of mirvetuximab in FRα-high, platinum-sensitive ovarian cancer (PSOC) has met the primary endpoint of objective response rate (ORR) based upon an interim assessment with no new safety signals identified. An ORR of at least 48% is expected when full data are reported in mid-2024.
Established a multi-target license and option agreement with ImmunoBiochem Corporation to develop next-generation ADCs.
Corporate
Appointed Lauren White as Senior Vice President and Chief Financial Officer, and Heather Adkins Huet, PhD, as Senior Vice President and Chief Scientific Officer.
ANTICIPATED UPCOMING EVENTS

Potential EMA approval of ELAHERE in late 2024 to support launch in Europe.
Our partner, Huadong Medicine, is planning for NMPA approval of ELAHERE by the end of 2024 to support launch in China.
Report data from the 802 trial, evaluating the pivekimab sunirine (pivekimab) triplet with Venclexta (venetoclax) and Vidaza (azacitidine) in frontline acute myeloid leukemia (AML) at the American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting in December 2023.
Report top-line data from the pivotal frontline de novo cohort in the Phase 2 CADENZA trial of pivekimab in blastic plasmacytoid dendritic cell neoplasm (BPDCN) in 2024.
Provide an update on the IMGC936 non-small cell lung cancer (NSCLC) cohort following a prespecified interim analysis.
FINANCIAL RESULTS
Total revenues were $113.4 million for the quarter ended September 30, 2023, including $105.2 million of net product revenues from sales of ELAHERE, compared to $15.4 million in total revenues for the quarter ended September 30, 2022. The increase was driven by ELAHERE net sales, partially offset by $7.4 million of license fees recorded as revenue in the prior year period pursuant to the Company’s collaboration agreements with Eli Lilly and Company and Novartis Institutes for BioMedical Research, Inc.
Research and development expenses were $47.6 million for the quarter ended September 30, 2023 compared to $59.2 million for the quarter ended September 30, 2022. The decrease was primarily driven by ELAHERE supply costs expensed in the prior quarter versus capitalized in the current period and lower hiring expenses. Partially offsetting these decreases, salaries and benefits increased driven largely by the expansion of our medical affairs organization.
Selling, general and administrative expenses were $37.7 million for the quarter ended September 30, 2023 compared to $33.6 million for the quarter ended September 30, 2022. The increase was due primarily to greater expenses in support of the US launch of ELAHERE, including costs related to the addition of our commercial organization and sales and marketing activities.
Net income for the third quarter of 2023 was $30.7 million, or $0.10 per basic and diluted share, compared to a net loss of $77.8 million, or $0.31 per basic and diluted share, for the third quarter of 2022.
ImmunoGen had $605.5 million in cash and cash equivalents and $130.7 million in accounts receivable as of September 30, 2023, compared with $275.1 million in cash and cash equivalents and $12.6 million in accounts receivable as of December 31, 2022. Cash used in operations was $137.7 million for the first nine months of 2023 compared with cash used in operations of $169.6 million for the same period in 2022. Capital expenditures were $1.6 million and $1.1 million for the first nine months of 2023 and 2022, respectively.
FINANCIAL GUIDANCE
ImmunoGen’s full year financial guidance for 2023 remains unchanged; the Company continues to expect:
revenues, excluding product revenue from ELAHERE, between $45 million and $50 million; and
operating expenses between $350 million and $365 million.
The Company continues to expect that its existing cash and cash equivalents, together with anticipated future product and collaboration revenues, will fund operations for more than two years.

ABOUT ELAHERE
ELAHERE (mirvetuximab soravtansine-gynx) is a first-in-class ADC comprising a folate receptor alpha-binding antibody, cleavable linker, and the maytansinoid payload DM4, a potent tubulin inhibitor designed to kill the targeted cancer cells.
ELAHERE is indicated for the treatment of adult patients with folate receptor-alpha (FRα) positive, platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer, who have received one to three prior systemic treatment regimens. Select patients for therapy based on an FDA-approved test.
This indication is approved under accelerated approval based on tumor response rate and durability of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.
Eye problems are common with ELAHERE and can be severe. ELAHERE also can cause severe or life-threatening inflammation of the lungs that may lead to death and patients may develop nerve problems called peripheral neuropathy during treatment. Please see full Prescribing Information, including Boxed Warning, and Medication Guide for ELAHERE.
