CAMBRIDGE, Mass., Feb. 27, 2020 (GLOBE NEWSWIRE) -- Jounce Therapeutics, Inc. (NASDAQ: JNCE), a clinical-stage company focused on the discovery and development of novel cancer immunotherapies and predictive biomarkers, today reported financial results for the fourth quarter and year ended December 31, 2019 and provided a corporate update.

“On the heels of a year of significant clinical progress in 2019, we have set the pace for a robust 2020 with the advancement of our vopratelimab Phase 2 studies, the ongoing EMERGE trial and the upcoming SELECT trial. The recent announcement of the TIS^vopra biomarker for patient selection in SELECT is a testament to our Translational Science Platform and further emphasizes our vision of bringing the right immunotherapy to the right patients,” said Richard Murray, Ph.D., chief executive officer and president of Jounce Therapeutics. “With two of our programs, vopratelimab and JTX-4014, in clinical trials, along with the advancement of our potential first-in-class monoclonal antibody, JTX-1811, into IND enabling activities, we are continuing to establish our differentiated approach to immunotherapy and clinical trial design. We look forward to executing on several key milestones in 2020 across our growing pipeline.”

Pipeline Update and Highlights:
Vopratelimab

• Established two development paths for vopratelimab program: In early 2019, Jounce announced two development paths for vopratelimab, which are now represented by two distinct and independent Phase 2 clinical trials, EMERGE and SELECT. Both trials are based on the biology related to the pharmacodynamic biomarker, ICOS hi CD4 T cells, which emerge in the blood of patients due to vopratelimab and not PD-1 inhibitors and are associated with clinical benefit.
    --  Enrollment on track in Phase 2 EMERGE trial: EMERGE trial enrollment in non-small cell lung cancer (NSCLC) remains on track, and Jounce expects to report preliminary efficacy and related biomarker data in the second half of 2020. 
    --  Identified the baseline TIS^vopra biomarker: In February 2020, Jounce presented new data announcing the identification of the predictive biomarker associated with vopratelimab patient selection, known as TIS^vopra, which will be used in the upcoming SELECT trial to select patients more likely to develop ICOS hi CD4 T cells and experience clinical benefit in the presence of vopratelimab. The TIS^vopra biomarker is a baseline RNA signature with a threshold optimized for the prediction of the emergence of ICOS hi CD4 T cells and is expected to predict for both vopratelimab and PD-1 activity.
    --  Announced trial design for upcoming Phase 2 SELECT trial: In January 2020, Jounce announced the trial design for SELECT, a randomized, ex-U.S. trial that will evaluate vopratelimab and JTX-4014, a PD-1 inhibitor, in patients with second line, PD-1 inhibitor naive NSCLC. Jounce expects to enroll approximately 75 patients, who will be selected using the TIS^vopra biomarker. Jounce expects to initiate the Phase 2 SELECT trial in mid-2020 and report interim clinical data in 2021.

JTX-4014

• Established JTX-4014 as combination agent for Phase 2 SELECT trial: Based on the results of the Phase 1 JTX-4014 trial announced in November 2019, Jounce plans to use JTX-4014 as the PD-1 inhibitor in combination with its other product candidates beginning with the upcoming Phase 2 SELECT trial.
• Presented safety and preliminary efficacy data from Phase 1 trial at the Society for Immunotherapy of Cancer’s (SITC) 34^th Annual Meeting: In November 2019, Jounce presented safety and preliminary efficacy data from the Phase 1 trial of JTX-4014 at SITC demonstrating anti-tumor activity with an overall RECIST 1.1 response rate of 16.7% (3/18), one complete response, two partial responses and a disease control rate of 44.4% (8/18) in patients with advanced refractory solid tumor malignancies and an average of over four lines of prior therapies. JTX-4014 was found to have an acceptable safety profile in this trial.

JTX-1811

• Named JTX-1811 as next development candidate from Translational Science Platform: In December 2019, JTX-1811 was selected as the next development candidate to emerge from Jounce's Translational Science Platform. JTX-1811 is a monoclonal antibody designed to selectively deplete immuno-suppressive T regulatory cells. Jounce will present additional preclinical data at the 2020 American Association for Cancer Research (AACR) annual meeting and expects to file an Investigational New Drug (IND) application in the first half of 2021.

Research Collaborations and Partnerships:

• Established research collaboration with NanoString Technologies to support the application of TIS^vopra in Phase 2 SELECT trial: In January 2020, Jounce entered into a new research collaboration with NanoString Technologies for the application of the TIS^vopra biomarker, including the optimized selection threshold in the SELECT trial. The TIS^vopra clinical trial assay will be implemented on the nCounter^® Dx Analysis System.
• Updated strategic collaboration with Celgene Corporation: In July 2019, Jounce and Celgene entered into a mutual agreement to terminate their broad strategic collaboration established in 2016. As a result, Jounce owns all global rights to its current pipeline, including vopratelimab, JTX-4014, JTX-1811 and all discovery-stage assets. Separately, Celgene obtained exclusive worldwide licensing rights to JTX-8064, a potential first-in-class antibody that targets the LILRB2 receptor on macrophages. Under the terms of the new license agreement, Jounce received a $50.0 million non-refundable license fee and is eligible to receive up to $480.0 million from Celgene in development, regulatory and commercial milestone payments, as well as royalties from potential worldwide sales.

Fourth Quarter and Full Year 2019 Financial Results:

• Cash position: As of December 31, 2019, cash, cash equivalents and investments were $170.4 million, compared to $195.9 million as of December 31, 2018. The decrease in cash, cash equivalents and investments was primarily due to operating costs incurred during the year, offset by the $50.0 million license fee received in July 2019 pursuant to Jounce’s JTX-8064 license agreement with Celgene.
• License and collaboration revenue: No license and collaboration revenue was recognized during the fourth quarter of 2019, compared to $20.1 million for the same period in 2018. License and collaboration revenue was $147.9 million for the full year 2019, compared to $65.2 million for the full year 2018. License and collaboration revenue recognized during 2019 was comprised of $50.0 million of cash revenue related to Jounce’s JTX-8064 license agreement with Celgene and $97.9 million of non-cash revenue recognition relating to the $225.0 million upfront payment received from Celgene in July 2016. License and collaboration revenue recognized during 2018 was comprised solely of non-cash revenue recognition related to the July 2016 upfront payment.
• Research and development expenses: Research and development expenses were $16.6 million for both the fourth quarter of 2019 and 2018. Research and development expenses were $67.1 million for the full year 2019, compared to $70.1 million for the full year 2018. The decrease in research and development expenses for the full year 2019 was primarily due to $6.0 million of decreased manufacturing and IND-enabling expenses as well as $0.9 million of decreased lab consumable costs. These decreases were partially offset by $3.1 million of increased employee compensation costs.
• General and administrative expenses: General and administrative expenses were $6.9 million for the fourth quarter of 2019, compared to $6.6 million for the same period in 2018 and $27.9 million for the full year 2019, compared to $26.4 million for the full year 2018. The increase in general and administrative expenses for both the fourth quarter of 2019 and the full year 2019 was primarily attributable to increased employee compensation costs.
• Net (loss) income: Net loss was $22.7 million for the fourth quarter of 2019, or a basic and diluted net loss per share of $0.68. Net loss was $2.0 million for the same period in 2018, or a basic and diluted net loss per share of $0.06. Net income was $56.8 million for the full year 2019, resulting in basic net income per share of $1.72 and diluted net income per share of $1.66. Net loss was $27.4 million for the full year 2018, or a basic and diluted net loss per share of $0.84. Net income recognized for the full year 2019 was primarily attributable to $147.9 million of license and collaboration revenue recognized under Jounce’s agreements with Celgene.

Financial Guidance:
Based on its current operating and development plans, Jounce expects gross cash burn on operating expenses and capital expenditures for the full year 2020 to be approximately $80.0 million to $95.0 million. Jounce will no longer provide license and collaboration revenue guidance as potential future payments under the JTX-8064 license agreement with Celgene are royalty- and milestone-based.

Given the strength of its balance sheet, Jounce expects its existing cash, cash equivalents and investments to be sufficient to enable the funding of its operating expenses and capital expenditure requirements through the end of 2021.
