CAMBRIDGE, Mass., Aug. 04, 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 second quarter ended June 30, 2022 and provided a corporate update.

"Jounce has made significant progress advancing our pipeline, and we look forward to sharing more details on our two ongoing clinical trials, INNATE and SELECT, later this year. Today, we are pleased to announce that we've completed enrollment in our randomized Phase 2 biomarker-selected trial SELECT, and plan to submit a clinical data abstract later this year to ESMO-IO being held in December. In addition, we expect to provide preliminary clinical and biomarker data across multiple cohorts from the Phase 2 portion of INNATE with an abstract submission to ESMO-IO in December. Our current financial position enables our continued growth and execution beyond the proof-of-concept inflection points of INNATE and SELECT, while continuing our robust, novel discovery efforts," said Richard Murray, Ph.D., chief executive officer and president of Jounce Therapeutics. "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)

Continued to advance INNATE Phase 2 trial across 7 indications. 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 cohorts in combination with pimivalimab. Each combination cohort is a Simon's 2-stage design, enrolling 10 patients for an initial analysis of response data, and then further expansion to a total of 29 patients if prespecified response criteria are met. Last quarter, Jounce announced the expansion of the first two combination cohorts. The expanded indications are 3rd/4th line PD-(L)1 inhibitor naive platinum-resistant ovarian cancer and 2nd/3rd line PD-(L)1 inhibitor resistant clear cell renal cell carcinoma. Having met the response criteria for expansion, both indications are 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 before year end. Jounce plans to submit a clinical abstract on preliminary clinical data including all 31 Phase 1 dose escalation patients and at least 80 Phase 2 combination treatment patients from INNATE, to the European Society of Medical Oncology (ESMO) Immuno-Oncology Congress 2022 being held from December 7-9 in Geneva, Switzerland. Phase 2 data will include safety, preliminary efficacy based on RECIST 1.1, pharmacodynamics, and potential predictive biomarker correlation with efficacy within each cohort, by prior PD-(L)1 inhibitor history, and in a cross-cohort analysis.

Vopratelimab (ICOS) and Pimivalimab (PD-1)

Patient enrollment complete in Phase 2 SELECT trial of vopratelimab. Patient enrollment is complete in the SELECT trial, a randomized Phase 2 trial evaluating vopratelimab, Jounce's inducible costimulator (ICOS) agonist, in combination with pimivalimab versus pimivalimab alone in immunotherapy naïve, TIS^vopra biomarker-selected, second line non-small cell lung cancer (NSCLC) patients.
On track to report clinical data before year end. Jounce plans to submit a clinical data abstract on the SELECT trial, including additional single agent data for pimivalimab, to the ESMO Immuno-Oncology Congress 2022.
First-in-human manuscript from the ICONIC trial in Clinical Cancer Research. A manuscript was recently published in the journal Clinical Cancer Research from the Phase 1/2 ICONIC trial of vopratelimab alone and in combination with nivolumab in patients with advanced solid tumors. Data from ICONIC identified TIS^vopra as a potential predictive biomarker currently being investigated in SELECT.

JTX-1484 (LILRB4/ILT3)

Continued advancement of JTX-1484. JTX-1484 is the most recent product to emerge from Jounce's Translational Science Platform and is a monoclonal antibody designed to block human LILRB4 (ILT3) 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 investigational new drug (IND) enabling activities, with the goal of filing an IND application in 2023. Jounce has submitted a preclinical abstract on JTX-1484 for consideration at this year's annual Society for Immunotherapy of Cancer (SITC) meeting being held from November 9-11 in Boston, MA.

Discovery Pipeline

LILRB family preclinical data abstract submitted to SITC. Jounce has submitted a LILRB family preclinical data abstract for consideration at this year's SITC annual meeting.
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.

Corporate Update:

Updates regarding the Board of Directors. Jigar Raythatha has become the Chair of the Board, replacing Perry Karsen who has served as the Chair since April of 2016. Perry Karsen will remain as a member of the board.
Key promotions across leadership team. Jounce is announcing that Hugh Cole is being promoted from Chief Business Officer to Chief Operating Officer, and Dr. Haley Laken is being promoted from Senior Vice President of Program and Portfolio Strategy to Chief Development Officer. Both Mr. Cole and Dr. Laken are impactful leaders within Jounce and Jounce congratulates them on their respective promotions.

Second Quarter 2022 Financial Results:

Cash position: As of June 30, 2022, cash, cash equivalents and investments decreased to $162.3 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 second quarter of 2022. License and collaboration revenue of $25.4 million was recognized during the second quarter of 2021 and was comprised of a $25.0 million clinical development and regulatory milestone for FDA clearance of the IND for GS-1811 and $0.4 million related to non-cash revenue for the performance of research and transition services, both under the Gilead License Agreement.
Research and development expenses: Research and development expenses were $26.2 million for the second quarter of 2022, compared to $22.1 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 lab supplies.
General and administrative expenses: General and administrative expenses were relatively flat at $7.5 million for the second quarter of 2022, compared to $7.3 million for the same period in 2021.
Net loss: Net loss was $33.5 million for the second quarter of 2022, resulting in basic and diluted net loss per share of $0.65. Net loss was $4.0 million for the same period in 2021, resulting in a basic and diluted net loss per share of $0.08. The increase in net loss is attributable to increased operating expenses and no revenue recognized under the Gilead License Agreement in the second quarter of 2022.

Financial Guidance:

Based on its current operating and development plans and cost containment efforts, Jounce is updating its financial guidance for 2022. Gross cash burn on operating expenses and capital expenditures for the full year 2022 is now expected to be at the lower end of the range of $115.0 million to $130.0 million. Jounce now expects its existing cash, cash equivalents and investments to be sufficient to enable the funding of its operating expenses and capital expenditure requirements into the first quarter of 2024.
