"More than half of patients whose disease progresses on enzalutamide or abiraterone, exhibit genetic aberrations in the AR gene in their tumors, confirming that the androgen receptor remains a principal driver of metastatic prostate cancer," noted John Houston, Ph.D., President and Chief Executive Officer of Arvinas. "Our preclinical data on oral AR PROTAC ARV-110 suggests that eliminating the receptor will be beneficial to patients, particularly those that would recur on standard of care."

The poster titled, "An oral androgen receptor PROTAC degrader for prostate cancer" (abstract 381), highlights the in vitro and in vivo pharmacodynamics and efficacy of ARV-110 in preclinical prostate cancer models. The studies show that degradation of the androgen receptor with ARV-110 leads to inhibition of AR target gene expression and the proliferation of prostate cancer cell lines. In both classical in vivo prostate cancer xenografts and enzalutamide-resistant prostate cancer models, ARV-110 is well tolerated and demonstrates robust efficacy at low oral doses, accompanied by AR degradation and inhibition of AR signaling.

Regulating AR signaling has long shown benefit in controlling the progression of prostate cancer but efficacy is limited using current standard of care AR inhibitors. Arvinas’ approach to addressing prostate cancer focuses on degrading the AR, resulting in more profound anti-cancer effects and differential biology, versus inhibition. Inhibition is a competitive process so increased androgen production, and increased expression of the AR and specific mutations of the receptor are well-studied mechanisms of resistance to AR inhibition. PROTAC-mediated degradation is an iterative, event-driven process, and therefore less susceptible to increases in endogenous ligand, target expression, or mutations in the target.

Abstracts are available on the Arvinas website under Publications at www.arvinas.com.

About PROTAC Platform

The PROTAC Platform offers potential improvements over traditional small molecule inhibitors by using the cell’s natural and selective ubiquitin- proteasome system to degrade disease-causing proteins. By removing target proteins directly rather than simply inhibiting them, PROTACs can provide multiple advantages over small molecule inhibitors which can require high systemic exposure to achieve sufficient inhibition, often resulting in toxic side effects and eventual drug resistance. With multiple protein targets, Arvinas’ PROTAC platform has demonstrated that a transient binding event at a range of binding sites and affinities can translate into very potent degradation of the target protein.

"We made significant progress with the business in 2017, with four consecutive quarters of strong execution across the Company. Operationally, we advanced our monotherapy registration study and published compelling combination data with mirvetuximab, expanded our clinical pipeline, and established a high-value partnership with Jazz Pharmaceuticals supporting our earlier-stage programs. Financially, we added over $235 million in cash and eliminated roughly $100 million in debt on the balance sheet through business development and financing transactions," said Mark Enyedy, ImmunoGen’s president and chief executive officer. "With the momentum we generated in the last twelve months, we enter 2018 from a position of strength with a number of important catalysts expected during the year. We anticipate completing patient enrollment in our FORWARD I Phase 3 registration trial by mid-year, multiple data readouts from our FORWARD II trial assessing combinations with mirvetuximab beginning next month at the Society of Gynecologic Oncology annual meeting, and clinical data from our Phase 1 trials of both IMGN779 and IMGN632 later in the year. With these anticipated events, we look forward to another productive year in 2018 as we advance our pipeline to bring new therapies to patients and create value for our shareholders."

Recent Pipeline Highlights

Activated more than 100 sites in North America and Europe in the Company’s ongoing Phase 3 FORWARD I trial of mirvetuximab soravtansine as single-agent therapy for platinum-resistant ovarian cancer enabling rapid patient enrollment;
Advanced the Company’s Phase 1b/2 FORWARD II trial in North America and Europe evaluating mirvetuximab soravtansine combination regimens in separate expansion cohorts with Keytruda (pembrolizumab) and Avastin (bevacizumab) for platinum-resistant disease, and initiated patient dosing in a new cohort to evaluate the triplet combination of mirvetuximab plus carboplatin and Avastin in patients with platinum-sensitive disease;
Reported updated safety data and preliminary anti-leukemia activity from the dose-escalation phase of the Phase 1 clinical trial of IMGN779 in patients with acute myeloid leukemia (AML) at the 2017 American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting;
Began dosing patients in the Company’s Phase 1 clinical trial of IMGN632, a CD123-targeting ADC integrating a potent DNA-alkylating payload intended to treat a range of hematological malignancies, including AML and blastic plasmacytoid dendritic cell neoplasm (BPDCN); and
Received notice that partner Takeda has filed an IND for TAK-164, an ADC directed to GCC-positive tumors using ImmunoGen’s IGN platform.
Facilities Update

Following an in-depth review of the Company’s manufacturing strategy, ImmunoGen will move to an operating model that will rely on external manufacturing and quality testing for drug substance and drug product for its development programs. The implementation of this new operating model will lead to the ramp-down of manufacturing and quality activities at the Company’s Norwood, Massachusetts facility by the end of 2018, with a full exit of the site by early 2019. Decommissioning the Norwood facility will result in anticipated cost savings of over $20 million during the next five years.
The Norwood facility has been a long-standing staple of ImmunoGen’s business, delivering high-quality products to patients and partners without interruption for more than 25 years. The Company is grateful for the contributions that its Norwood-based employees have made and will support these employees through the transition.

Financial Results

As previously disclosed, effective January 1, 2017, ImmunoGen transitioned to a fiscal year ending December 31. The years ended December 31, 2017 and 2016 reflect the twelve-month results of the respective calendar years.

Revenues for the year ended December 31, 2017 were $115.4 million, compared to $48.6 million for the year ended December 31, 2016. License and milestone fees of $79.5 million for 2017 included a $30 million paid-up license fee related to an amendment to the Company’s collaboration and license agreement with Sanofi, $29.5 million related to the sale and transfer of the Company’s IMGN529 asset to Debiopharm, $7 million in partner milestone payments and $12.7 million in amortization of a non-cash fee related to the Company’s license agreement with CytomX, compared to $15 million in partner milestone payments received in 2016. Revenues for 2017 included $28.1 million in non-cash royalty revenues, compared with $26.2 million in non-cash royalty revenues for 2016. Revenues for 2017 also included $3.5 million of research and development (R&D) support fees and $4.4 million of clinical materials revenue, compared with $5.2 million and $1.9 million, respectively, for 2016.

Operating expenses, including R&D and G&A expenses, for 2017 were $174.4 million, compared to $184.3 million for 2016. R&D expenses for 2017 decreased to $139.7 million, compared to $141.3 million for 2016, primarily due to a workforce reduction resulting from the strategic review in September 2016 and lower third-party service fees, partially offset by increased clinical trial and drug supply costs driven largely by the advancement of the FORWARD I Phase 3 clinical trial. General and administrative expenses decreased in 2017 to $33.9 million, compared to $38.5 million in 2016, primarily due to lower personnel expenses. Operating expenses for 2016 also included a $4.4 million restructuring charge related to the workforce reduction and a loss on leased office space, compared to a $0.8 million charge in 2017 related to additional loss recorded on leased office space.

In September and November 2017, a total of $97.9 million of convertible debt outstanding was converted into 26.2 million shares of the Company’s common stock, resulting in a $22.9 million non-cash debt conversion charge recorded in 2017. With this conversion, the Company’s outstanding debt is reduced to $2.1 million. In October 2017, pursuant to a public offering, the Company sold an aggregate of 16.7 million shares of its common stock, with net proceeds to the Company of $101.7 million, after deducting underwriting discounts and offering expenses.

ImmunoGen reported a net loss of $96.0 million, or $0.98 per basic and diluted share, for 2017, which included a loss of $0.23 per basic and diluted share relating to the non-cash debt conversion charge, compared to a net loss of $156.7 million, or $1.80 per basic and diluted share, for 2016.

ImmunoGen had $267.1 million in cash and cash equivalents as of December 31, 2017, compared with $160.0 million as of December 31, 2016, and had $2.1 million and $100.0 million of convertible debt outstanding as of December 31, 2017 and December 31, 2016, respectively. Cash provided by operations was $7.6 million for 2017, compared with cash used in operations of $(142.6) million for 2016. The current year benefited from $59.5 million of fees received from Sanofi and Debiopharm, which were included in revenue for 2017, and a $75 million upfront payment received from Jazz, which is included in deferred revenue as of December 31, 2017. Capital expenditures were $1.1 million and $6.7 million for 2017 and 2016, respectively.

Financial Guidance

For 2018, ImmunoGen expects:

revenues between $60 million and $65 million;
operating expenses between $185 million and $190 million; and
cash and cash equivalents at December 31, 2018 between $115 million and $120 million.
