Biologics License Application (BLA) Accepted for Filing and Granted Priority Review by the U.S. Food and Drug Administration (FDA)

U.S. Commercial Launch Preparations on Track

Lifecycle Management Strategy Implemented to Advance Sacituzumab Govitecan to Earlier Lines of Therapies and Broaden into Other Solid Cancer Indications

MORRIS PLAINS, N.J., Aug. 23, 2018 (GLOBE NEWSWIRE) -- Immunomedics, Inc., (NASDAQ:IMMU) (“Immunomedics” or the “Company”), a leading biopharmaceutical company in the area of antibody-drug conjugates (ADC), today reported financial results for the fourth quarter and fiscal year ended June 30, 2018. The Company also highlighted recent key progress and planned activities for its sacituzumab govitecan program. Please refer to the Company’s Annual Report on Form 10-K filed today with the SEC for more details on the Company’s financial results.

“We reached a historical milestone this past quarter when we submitted our first BLA for sacituzumab govitecan, which was accepted for filing and granted Priority Review by the FDA with a Prescription Drug User Fee Act (PDUFA) target action date of January 18, 2019. We are working closely with the FDA as we strive to bring this potential new treatment to metastatic triple-negative breast cancer (mTNBC) patients expeditiously,” stated Michael Pehl, President and Chief Executive Officer of Immunomedics. “Through our recent capital raise we have further strengthened our balance sheet which we believe will allow us to implement our lifecycle management strategy for this valuable asset for the benefit of patients beyond third-line mTNBC while our preparations for commercial launch in the US are progressing well.”

Highlights of Recent Progress

-- A BLA for sacituzumab govitecan for the treatment of patients with mTNBC who previously received at least two prior therapies for metastatic disease was submitted to the FDA, which has accepted it for filing and granted Priority Review with a PDUFA target action date of January 18, 2019. If approved, sacituzumab govitecan would be the first and only ADC approved for the treatment of mTNBC. -- A pivotal Phase 2 TROPHY U-01 study of sacituzumab govitecan was initiated in patients with locally advanced or mUC who have relapsed after a platinum-based regimen and/or immune checkpoint therapy. -- At the 2018 ASCO Annual Meeting, promising data for sacituzumab govitecan in patients heavily-pretreated for metastatic estrogen receptor-positive breast cancer were presented. -- A clinical collaboration was entered into between the Company and AstraZeneca and its global biologics research and development arm, MedImmune, to evaluate the combination of AstraZeneca’s durvalumab and sacituzumab govitecan in first-line TNBC and UC. -- Immunomedics is also collaborating with Clovis Oncology to investigate the combination of Clovis’ rucaparib and sacituzumab govitecan as a treatment of patients with mTNBC and mUC. -- Multiple clinical and preclinical collaborations with prominent cancer research institutions were established to potentially broaden sacituzumab govitecan into other solid cancer indications including endometrial, cervical, and head and neck cancers. -- The Company raised approximately $300 million in net proceeds through a public offering of common stock.

Fourth Quarter and Full-Year Fiscal 2018 Results

Total revenues were $0.4 million for the fourth fiscal quarter ended June 30, 2018 and $2.2 million for the fiscal year ended June 30, 2018, compared to $0.6 million in the fourth quarter and $3.1 million for the fiscal year ended June 30, 2017. The decreases were due primarily to lower sales volume of LeukoScan® in Europe. The Company discontinued the sale of LeukoScan® during the third quarter of fiscal 2018 to focus on its ADC business.

Total costs and expenses were $52.8 million for the quarter and $143.2 million for the fiscal year ended June 30, 2018, compared to $27.4 million in the fourth quarter and $82.2 million for the fiscal year ended June 30, 2017. The higher costs and expenses were due primarily to increased expenses in research and development, general and administrative, and sales and marketing.

The increases in research and development costs were due primarily to preparations for the approval and launch of sacituzumab govitecan in the United States for patients with mTNBC, as well as increases in outside manufacturers’ organizational services and outside consulting services costs associated with the Phase 3 ASCENT trial.

The increases in general and administrative expenses were due primarily to increased labor costs associated with the anticipated launch of sacituzumab govitecan in the U.S. for patients with mTNBC. The increases in sales and marketing expenses were due primarily to commercial launch preparation activities.

The Company recognized $58.9 million in non-cash expense in the fourth quarter and $108.6 million for the fiscal year ended June 30, 2018, compared to $25.5 million in the fourth quarter and $61.1 million for the fiscal year ended June 30, 2017. The increases were due to the net appreciation in the fair value of outstanding warrants. For the fiscal year ended June 30, 2018, the Company also recognized a $13.0 million non-cash expense on induced exchanges of debt related to the Convertible Senior Notes.

Interest expense was $9.4 million in the fourth quarter and $23.3 million for the fiscal year ended June 30, 2018, compared to $1.4 million in the fourth quarter and $5.5 million for the fiscal year ended June 30, 2017. The increases were due primarily to increased debt balances as a result of the agreement with RPI Finance Trust.

For the fiscal year ended June 30, 2018, the Company received $6.6 million non-recurring insurance reimbursements related to legal costs incurred during the Company's proxy contest in fiscal 2017.

Net loss attributable to stockholders was $117.0 million, or $0.68 per share, for the quarter ended June 30, 2018, compared to $53.3 million, or $0.48 per share, for the same quarter in fiscal 2017. Net loss attributable to stockholders was $273.8 million, or $1.78 per share, for the fiscal year ended June 30, 2018, compared to $153.2 million, or $1.47 per share, for the same period in fiscal 2017.

As of June 30, 2018, the Company had $638.8 million in cash, cash equivalents, and marketable securities, which it believes is sufficient to support its next phase of growth and the execution of key commercial, clinical and regulatory strategic initiatives.
