ImmunoGen, Inc. (Nasdaq: IMGN), a biotechnology company that develops anticancer therapeutics using its Targeted Antibody Payload (TAP) antibody-drug conjugate (ADC) technology, today reported financial results for the three-month period and fiscal year ended June 30, 2013. ImmunoGen also provided guidance for its 2014 fiscal year and an update on the Company.
“We are starting to see the first commercial rewards from our many years of scientific innovation,” commented Daniel Junius, President and CEO. “Kadcyla sales are off to a strong start in the US for its first indication, with many additional approvals expected. It is particularly gratifying to hear from patients about the difference Kadcyla is making for them and their caregivers.”
Mr. Junius continued, “We’re using our industry-leading technology and expertise to develop a pipeline of wholly owned compounds for cancers with significant unmet need today. We plan to meaningfully advance our clinical-stage pipeline over the course of this fiscal year, with achievements expected to include: initiation of clinical testing with our IMGN289 product candidate; presentation of additional clinical data for IMGN853; making a next-step decision for IMGN901; and having the dosing information needed to begin evaluation of our IMGN529 compound in specific non-Hodgkin’s lymphoma subtypes. We also expect a number of partner-related events over the course of this fiscal year. For Kadcyla alone, we’re expecting a decision about approval in the European Union and presentation of data from the TH3RESA trial within the next few months.”
Product Pipeline Update
- Kadcyla is an approved product that utilizes the Company’s TAP technology. It is being developed and commercialized by Roche under an agreement with ImmunoGen. ImmunoGen receives and recognizes royalties on Kadcyla sales one quarter after the sales are reported by Roche.Kadcyla gained FDA marketing approval in the US on February 22, 2013 for the treatment of people with HER2-positive metastatic breast cancer (BC) who had received prior treatment with Herceptin ® (trastuzumab) and a taxane. Roche reported “strong uptake” of Kadcyla in the US, with year-to-date sales of 82 million CHF (approximately $87 million) through June 30, 2013.Kadcyla was approved in Switzerland in May 2013, and Roche reported sales through June 30 of 1 MM CHF. Roche expects a decision about approval in the EU in 2H2013. A marketing application is also under review in Japan.Roche is assessing Kadcyla in a number of additional indications, including for first-line treatment of HER2-positive metastatic BC (MARIANNE trial), for uses in early stage HER2-positive BC (including the KATHERINE trial), and for the treatment of advanced HER2-positive stomach cancer (GATSBY trial). The progression-free survival (PFS) endpoint of TH3RESA has been met, and Roche intends to submit these data for presentation at the ESMO annual meeting Sept. 27-Oct. 1, 2013. Roche expects results from MARIANNE in late 2014 and to apply for first-line treatment of HER2-positive metastatic BC and for treatment of advanced HER2-positive gastric cancer in 2015.
- IMGN901 is ImmunoGen’s lead wholly owned product candidate and is being evaluated for first-line treatment of small-cell lung cancer (SCLC). Its target, CD56, is found on a variety of cancers, including SCLC, other tumors of neuroendocrine origin, and multiple myeloma.The Company’s NORTH Phase II trial is designed to assess whether the addition of IMGN901 to standard of care etoposide/carboplatin (E/C) provides a meaningful benefit over E/C alone as first-line treatment for newly diagnosed, extensive disease SCLC. The primary endpoint is progression-free survival (PFS), with objective response rate and overall survival (OS) among the secondary endpoints. Current first-line therapy for this cancer has a median PFS of 5-5.5 months and OS of 9-11 months.ImmunoGen expects to complete patient enrollment this quarter and to have the data needed to make next-step decisions for the compound by mid-2014. The Company expects NORTH clinical data will be reported at one or more medical conferences in 2014.
- IMGN853 is a potential new therapy for ovarian, endometrial, and adenocarcinoma lung cancers, as well as other cancers that overexpress its folate receptor α (FRα) target. This TAP compound is also wholly owned by ImmunoGen.The first IMGN853 clinical data were reported at the ASCO annual meeting in June 2013. They were from the dose-escalation part of the Phase I trial underway, which is designed to establish the IMGN853 dose for the expansion phase of the trial. Dose levels ranging from 0.15 to 7.0 mg/kg had been evaluated, and at the time of data cut-off for presentation, the 5.0 mg/kg dose was being further explored. Evidence of activity was reported in patients with strong FRα expression who had received IMGN853 at doses of 3.3 mg/kg or above.ImmunoGen expects to start the expansion phase of this trial later this year, and to report updated findings from it in disease-specific populations in mid-2014.
- IMGN289 is ImmunoGen’s third wholly owned TAP compound for solid tumor indications, and is a potential new treatment for EGFR-positive cancers, including most squamous cell lung and head and neck cancers.In preclinical testing, IMGN289 was found to be highly active against cancer cells resistant to EGFR inhibiting agents − including tyrosine kinase inhibitors (TKIs) – as well as those responsive to EGFR inhibition. This is attributed to the ability of IMGN289 to kill cancer cells directly with its potent cytotoxic component as well as through EGFR inhibition. The IMGN289 Investigational New Drug (IND) application is now active and ImmunoGen expects to begin its clinical testing by the end of 2013.
- IMGN529 is ImmunoGen’s lead wholly owned TAP compound for hematological malignancies. It is a potential treatment for CD37-positive non-Hodgkin’s lymphoma (NHL) and chronic lymphocytic leukemia (CLL), and is currently in Phase I testing for NHL.
- In addition to Kadcyla, six other TAP compounds and a CD38-targeting therapeutic antibody are in clinical testing through ImmunoGen’s collaborative partnerships, with additional compounds progressing preclinically.
