CAMBRIDGE, Mass., May 05, 2022 (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 first quarter ended March 31, 2022 and provided a corporate update.

"Jounce made significant progress this quarter as we focused on the continued advancement of our two proof of concept studies, INNATE and SELECT, in addition to advancing candidates from our discovery engine, such as JTX-1484, our LILRB4 (or ILT3) inhibitor. With our cash runway extending beyond our key inflection points, we are poised for an important second half of this year," said Richard Murray, Ph.D., chief executive officer and president of Jounce Therapeutics. "I'm very pleased to share that we recently met the prespecified response criteria in two combination cohorts to continue the Phase 2 expansion in the INNATE trial, and, in our SELECT trial, we have achieved target enrollment. These achievements represent significant progress in building our pipeline of diverse immunotherapy candidates. We continue to focus on our mission of delivering meaningful and long-lasting benefit to cancer patients through the discovery and pursuit of therapies that target new mechanisms of immune suppression across different types of immune cells, and bringing the right immunotherapies to the right patients."

Pipeline Update & Highlights:

JTX-8064 (LILRB2/ILT4)

• Expanded two of seven combination cohorts in INNATE Phase 2 trial. Jounce is evaluating JTX-8064 in the ongoing Phase 2 portion of the INNATE clinical trial, which is comprised of indication specific expansion cohorts, including one monotherapy cohort and seven combination therapy cohorts. Each cohort is a Simon 2-stage design, in which we enroll 10 patients, wait for initial response data, and then further expand to a total of 29 patients if prespecified response criteria are met. Today, Jounce is announcing that the first two combination cohorts have met their response criteria for expansion within INNATE and are now continuing enrollment to 29 patients each. Jounce has seen an acceptable safety profile for both the monotherapy and combination therapy to date.
  
  
  
  
• On track to report preliminary clinical data in the second half of 2022. The INNATE clinical trial is studying three distinct patient populations across the 7 indications: (1) PD-1 inhibitor naïve patients with tumors for which there are approved PD-1 or PD-L1 inhibitors, (2) PD-(L)1 inhibitor naïve patients who have tumors for which there are no PD-1 or PD-L1 inhibitors approved and (3) patients who were previously treated with a PD-1 inhibitor and are PD-1 inhibitor resistant. Jounce remains on track to report preliminary clinical data, including all 31 dose escalation patients and at least 60 Phase 2 patients from INNATE, in the second half of 2022.
  
  

Vopratelimab (ICOS) and Pimivalimab (PD-1)

• Patient screening finished in the Phase 2 SELECT trial of vopratelimab. Patient screening is complete with the target enrollment of at least 60 evaluable patients having been met in SELECT, a randomized Phase 2 trial evaluating vopratelimab in combination with pimivalimab versus pimivalimab alone in immunotherapy naïve, TIS^vopra biomarker-selected, second line non-small cell lung cancer (NSCLC) patients. Jounce is on track to report data from the SELECT trial in the second half of 2022, including additional single agent data for pimivalimab.
  
  

JTX-1484 (LILRB4/ILT3)

• JTX-1484 is the most recent product candidate to emerge from our Translational Science Platform. JTX-1484 is a monoclonal antibody designed to block human LILRB4 expressed on myeloid cells in the tumor microenvironment with the potential to reduce immune suppression and enhance T cell functionality. JTX-1484 is currently in IND-enabling activities, with the goal of filing an investigational new drug application ("IND") in 2023.
  
  

Discovery Pipeline

• Productive discovery engine with the goal of an IND every 12 to 18 months: Jounce continues to invest in and advance its growing immuno-oncology pipeline. Its discovery engine is built upon the capability to thoroughly interrogate different cell types in the tumor microenvironment, including T cells and myeloid cells. This approach has resulted in four clinical stage programs, with a fifth in IND enabling studies, over the last 6 years.
  
  

First Quarter 2022 Financial Results:

• Cash position: As of March 31, 2022, cash, cash equivalents and investments decreased to $186.4 million, compared to $220.2 million as of December 31, 2021. The decrease was due to operating expenses incurred during the period.
• License and collaboration revenue: Jounce did not recognize any revenue during the first quarter of 2022. License and collaboration revenue of $1.5 million was recognized during the first quarter of 2021 and was comprised solely of non-cash revenue related to the performance of research and transition services under the Gilead License Agreement.
• Research and development expenses: Research and development expenses were $30.1 million for the first quarter of 2022, compared to $20.5 million for the same period in 2021. The increase in research and development expenses was primarily due to increased manufacturing activities performed for Jounce's development programs, increased clinical and regulatory costs for INNATE, and increased payroll and stock-based compensation expense.
• General and administrative expenses: General and administrative expenses were $7.3 million for the first quarter of 2022, compared to $7.6 million for the same period in 2021. The decrease in general and administrative expenses was primarily due to decreased external consulting and stock-based compensation expense.
• Net loss: Net loss was $37.4 million for the first quarter of 2022, resulting in basic and diluted net loss per share of $0.72. Net loss was $26.5 million for the same period in 2021, resulting in a basic and diluted net loss per share of $0.58. The increase in net loss was primarily attributable to increased operating expenses incurred during the first quarter of 2022.
  
  

Financial Guidance:

Based on its current operating and development plans, Jounce reiterates its financial guidance for 2022. Gross cash burn on operating expenses and capital expenditures for the full year 2022 is expected to be approximately $115.0 million to $130.0 million. 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 third quarter of 2023.

Jounce currently has multiple development stage programs ongoing while simultaneously advancing additional early-stage assets from its robust discovery engine based on its Translational Science Platform. Jounce's highest priority program, JTX-8064, is a LILRB2 (ILT4) receptor antagonist shown to reprogram immune-suppressive tumor associated macrophages to an anti-tumor state in preclinical studies. JTX-8064 is currently being investigated alone and in combination with pimivalimab (formerly JTX-4014), Jounce's internal PD-1 inhibitor, in one monotherapy and seven indication-specific combination therapy cohorts in the Phase 1/2 INNATE trial and is currently enrolling patients with advanced solid tumors in the Phase 2 portion of the study. Jounce's most advanced product candidate, vopratelimab, is a monoclonal antibody that binds to and activates ICOS, and is currently being studied in the SELECT Phase 2 trial. Pimivalimab is a PD-1 inhibitor intended for combination use in the INNATE and SELECT trials and with Jounce's broader pipeline. Additionally, Jounce exclusively licensed worldwide rights to GS-1811 (formerly JTX-1811), a monoclonal antibody targeting CCR8 and designed to selectively deplete T regulatory cells in the tumor microenvironment, to Gilead Sciences, Inc.
