"Our clinical and corporate execution in 2018 places UroGen in a position of strength as we prepare to potentially deliver UGN-101 as the first approved therapy for patients with low-grade upper tract urothelial cancer (LG UTUC)," said Liz Barrett, President and Chief Executive Officer of UroGen. "With this solid foundation, we remain intensely focused on finalizing our rolling New Drug Application (NDA) and accelerating commercial preparation to ensure a successful launch upon approval with seamless adoption of UGN-101. We believe UGN-101 is just the beginning of what may be possible with our proprietary RTGel technology platform."

"LG UTUC represents a clinical challenge as the current treatment of surgical intervention can put patients at risk for the well-known complications associated with repetitive surgical procedures and potential kidney removal," said Mark P. Schoenberg, M.D., Chief Medical Officer of UroGen. "If approved, UGN-101 could be a true breakthrough for patients by providing an option to avoid the risks and downstream consequences associated with surgery while arming urologists in general practice with a simple-to-use, kidney sparing approach to the management of their patient’s disease."

Recent Highlights

UGN-101 Clinical Development:

In the fourth quarter, the U.S. Food and Drug Administration (FDA) granted Breakthrough Therapy Designation (BTD) for UGN-101 (mitomycin gel) for instillation, an investigational mitomycin formulation for the non-surgical treatment of patients with LG UTUC.

In January 2019, the Company announced positive topline results from the pivotal Phase 3 OLYMPUS clinical trial of UGN-101, in which 57 percent of patients achieved a complete response (CR) rate at their primary disease evaluation (PDE, or the primary endpoint) which was conducted four to six weeks after completion of UGN-101 treatment.

Pipeline Advancement:

The Company continues to enroll patients as part of its Phase 2b OPTIMA II clinical trial of UGN-102 (mitomycin gel) for intravesical instillation as a potential first-line chemoablation agent in the treatment of intermediate risk patients with low-grade non-muscle invasive bladder cancer (LG NMIBC) at risk for recurrence.

Corporate Developments:

UroGen strengthened its leadership team with the appointment of Liz Barrett as President and Chief Executive Officer. Ms. Barrett has over 30 years of industry experience spanning multiple areas including oncology, specialty care, surgical franchises, and consumer marketing in multiple geographic regions, most recently serving as CEO of Novartis Oncology and as a member of the Executive Committee of Novartis.

The Company enhanced its financial position with the completion of a successful public offering of ordinary shares in January 2019, resulting in net proceeds of approximately $162 million. These proceeds leave the company well-capitalized to execute on upcoming milestones, including preparation for potential commercialization of UGN-101, continued clinical development of our second product candidate (UGN-102), and advancement of our pipeline.

Upcoming Milestones:

UGN-101: UroGen remains on track to complete its rolling NDA for UGN-101 in 2H 2019 and is planning for potential approval in 1H 2020. If approved, UGN-101 would be the first drug approved for the non-surgical treatment of LG UTUC.

The company continues to build out its commercial infrastructure and focus on scientific awareness to support adoption and seamless integration of UGN-101 into the urologist practice following potential regulatory approval.

UGN-102: The Company intends to report initial data from the OPTIMA II trial of UGN-102 in 2019.

Similar to UGN-101, UGN-102 has the potential to transform the treatment paradigm for patients with LG NMIBC, as there are currently no drugs approved by the FDA as first-line treatment for LG NMIBC.

UGN-102 represents a substantial opportunity in UroGen’s pipeline with the potential to initially address up to approximately 80,000 patients for whom repetitive surgical resection via Transurethral Resection of Bladder Tumor (TURBT) remains the standard of care.

BotuGel: Allergan continues to enroll patients in its Phase 2 trial of BotuGel, UroGen’s RTGel in combination with BOTOX1, for the treatment of overactive bladder. Phase 2 data is expected in 2019.

Fourth Quarter and Full Year 2018 Financial Results; 2019 Guidance

As of December 31, 2018, cash, cash equivalents, and short-term investments totaled $101.3 million. In addition, the Company raised net proceeds of approximately $162 million from an underwritten public offering in January 2019. Based on anticipated activities, the current cash balance is projected to carry the company for the next 24-36 months.

Research and development expenses for the year ended December 31, 2018 were $36.9 million, including non-cash share-based compensation expense of $12.0 million. Research and development expenses for the three months ended December 31, 2018 were $11.5 million, including non-cash share-based compensation expense of $3.0 million.

General and administrative expenses for the year ended December 31, 2018 were $39.6 million, including non-cash share-based compensation expense of $18.6 million. General and administrative expenses for the three months ended December 31, 2018 were $12.6 million, including non-cash share-based compensation expense of $5.9 million.

The Company reported a net loss of $75.7 million, or basic and diluted net loss per ordinary share of $4.80, for the year ended December 31, 2018. The Company reported a net loss of $23.7

BOTOX is a proprietary trademark of Allergan Pharmaceuticals

million, or basic and diluted net loss per ordinary share of $1.46, for the three months ended December 31, 2018.

The Company anticipates a net loss in the range of $100 to $115 million for 2019, which is expected to include non-cash stock-based compensation expense in the range of $24 to $27 million subject to market conditions. The projected change in net loss for 2019 versus 2018 is expected to be largely attributable to the buildout of commercial infrastructure in anticipation of the potential launch of UGN-101. The Company has 20.4 million ordinary shares outstanding post the closing of our most recent financing in January.

"2018 was a very productive year for Spectrum in which our two promising pipeline products significantly progressed in clinical development," said Joe Turgeon, President and CEO of Spectrum Pharmaceuticals. "We begin 2019 with great momentum after meeting the enrollment target for the first cohort in our pivotal poziotinib study and submitting the BLA for ROLONTIS to the FDA at the end of 2018. In 2019, we are laser-focused on continuing to develop our two late-stage products, poziotinib and ROLONTIS, and looking for new opportunities that build upon these assets."

Pipeline update:

Poziotinib, an irreversible tyrosine kinase inhibitor targeting EGFR and HER2 mutations:

Enrollment in the EGFR, previously treated NSCLC cohort (cohort 1) in the ZENITH20 trial was completed; topline results are expected in Q4 2019.
Enrollment in the HER2, previously treated NSCLC cohort (cohort 2) in the ZENITH20 trial is expected to be completed in Q4 2019.
Initiation of pan-tumor and combination trials expected to be in H2 2019.
ROLONTIS (eflapegrastim), a novel long-acting GCSF:

Spectrum submitted the BLA with the FDA in late December 2018. Due to the government shutdown, the file was officially received on January 28, 2019.
Pipeline update continued:

Spectrum has begun launch readiness activities including inventory build and commercial preparedness.
Data from the Phase 3 study (RECOVER) was presented in a poster session at the San Antonio Breast Cancer Symposium in December 2018. The RECOVER study was the second pivotal trial to meet all primary and secondary endpoints and demonstrated comparable safety and tolerability profiles to pegfilgrastim.
2019 Guidance

Assuming the previously announced divestiture transaction closes in March, we expect 2019 SG&A costs to decrease by approximately 30 percent relative to 2018. We expect 2019 R&D costs to increase nominally as reduced spending on the legacy assets is offset by the increased spending on pre-commercial supply and tech transfer activities for ROLONTIS and poziotinib. With the increase of cash from the sale of our commercial assets, we expect our cash balance to be sufficient to fund operations for at least three years.

On February 28, 2019 TG Therapeutics, Inc. (NASDAQ: TGTX), a biopharmaceutical company developing medicines for patients with B-cell mediated diseases, reported that the Marginal Zone Lymphoma (MZL) cohort of the UNITY-NHL Phase 2b pivotal trial evaluating umbralisib (TGR-1202), our novel, once daily, PI3K delta inhibitor, met the primary endpoint of Overall Response Rate (ORR) as determined by Independent Review Committee (IRC) for all treated patients (n=69) (Press release, Manhattan Pharmaceuticals, FEB 28, 2019, View Source [SID1234533795]). The results met the Company’s target guidance of 40-50% ORR.

Interim safety and efficacy data from this study will be presented in an oral presentation at the upcoming American Association of Cancer Research (AACR) (Free AACR Whitepaper) annual meeting on April 1, 2019 and full data from this study are expected to be presented at a medical meeting later this year. The company plans to discuss the results with the U.S. Food and Drug Administration (FDA) regarding a potential new drug application (NDA) filing for accelerated approval. Umbralisib was recently granted Breakthrough Therapy Designation (BTD) by the FDA for the treatment of adult patients with MZL who have received at least one prior anti-CD20 regimen.

Michael S. Weiss, Executive Chairman and Chief Executive Officer of TG Therapeutics stated, "We are extremely pleased to announce that the UNITY-NHL marginal zone lymphoma cohort evaluating umbralisib monotherapy met the primary endpoint of ORR. While this was an early look at the response data, we were excited to have already met the target ORR, which we previously stated was approximately 40%-50%. Importantly, with many patients still on study, we anticipate the ORR will continue to improve with additional follow-up, which will also provide us with critical information on duration of response, progression free survival and long-term safety and tolerability necessary to support an NDA filing."

Mr. Weiss continued, "There are no fully approved drugs for MZL, and thus remains an unmet medical need and we are excited by the potential to offer a novel treatment for this underserved population. We look forward to discussing the results with the FDA as soon as possible and if all goes well, we believe we could be in a position to file for accelerated approval for umbralisib by year-end."

About the UNITY-NHL Phase 2b Study—Marginal Zone Lymphoma Cohort

The multicenter, open-label, UNITY-NHL Phase 2b study – Marginal Zone Lymphoma cohort was designed to evaluate the safety and efficacy of single agent umbralisib, the Company’s novel, once daily, PI3K delta inhibitor, in patients with MZL who have received at least one prior anti-CD20 regimen. The primary endpoint is overall response rate (ORR) as determined by Independent Review Committee (IRC) assessment. The primary analysis of ORR will be conducted once all treated patients have had at least 9 cycles (Cycle = 28 days) of follow-up. Secondary endpoints include safety, duration of response, and progression-free survival (PFS).

The MZL cohort completed enrollment in August 2018 with a total of 69 patients enrolled and receiving at least one dose of umbralisib. The positive ORR outcome announced today was based on all 69 enrolled and treated patients, however at this time all patients have not yet been followed for a minimum of 9 cycles as required for the primary analysis of ORR. Accordingly, the study is on-going and patients with benefit on therapy (stable disease or in response) remain on study. Safety data are currently being analyzed.

ABOUT MARGINAL ZONE LYMPHOMA

Marginal zone lymphoma (MZL) comprises a group of indolent (slow growing) B-cell non-Hodgkin lymphomas (NHLs) that begin forming in the marginal zone of lymphoid tissue. With an annual incidence of approximately 7,500 newly diagnosed patients, MZL is the third most common B-cell NHL accounting for approximately eight percent of all NHL cases.i MZL consists of three different subtypes: extranodal MZL of the mucosal-associated lymphoid tissue (MALT), nodal marginal zone lymphoma (NMZL), and splenic marginal zone lymphoma (SMZL).

ABOUT BREAKTHROUGH THERAPY DESIGNATION

The FDA’s Breakthrough Therapy designation is intended to expedite the development and review of a drug candidate that is planned to treat a serious or life-threatening disease or condition and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement on one or more clinically significant endpoints over available therapies.
