"Jounce has had another very productive quarter as we have made significant progress across all areas of the company and continue to build momentum as we head into the new year. We were pleased to report that we are now actively recruiting patients in the monotherapy and combination therapy expansion portion of the INNATE study, testing JTX-8064 +/- pimivalimab, our own PD-1 inhibitor, in 8 distinct cohorts across 7 tumor types. We also continue to advance patient enrollment in our randomized SELECT study which employs our stringent patient selection strategy and have continued our commitment to build our discovery pipeline," said Richard Murray, Ph.D., chief executive officer and president of Jounce Therapeutics. "We believe our focus on translational science, biomarker approaches, and targeting new immune mechanisms leads us closer to bringing the right immunotherapies to the right patients."
Pipeline Update:
JTX-8064 (LILRB2 / ILT4)
Completed monotherapy and combination therapy dose escalation 3 week safety review of INNATE: Jounce has completed the monotherapy and pimivalimab (PD-1 Inhibitor) combination therapy dose escalation 3 week safety review of the Phase 1 trial of JTX-8064, and a preliminary recommended phase 2 dose (RP2D) of 700 mg has been established. To date, JTX-8064 has been well tolerated with no dose limiting toxicities.
Enrollment initiated in tumor-specific monotherapy and pimivalimab combination expansion cohorts of INNATE: Jounce previously announced the initiation of patient enrollment in INNATE tumor-specific expansion cohorts for both JTX-8064 monotherapy and combination therapy of JTX-8064 with pimivalimab in August and October, respectively. The expansion cohorts will study JTX-8064 in three subsets of patients in order to identify the most rapid development paths for JTX-8064 alone or in combination with PD-1 inhibitors:
Patients who have progressed on PD-1 inhibitors and are now PD-1 inhibitor resistant,
PD-1 inhibitor naïve patients with tumors that do not typically respond to PD-1 inhibitors, and
PD-1 inhibitor naïve patients with tumors for which PD-1 inhibitors are approved, but there is still room for improvement.
Vopratelimab (ICOS) and Pimivalimab (PD-1)
Continued enrollment in Phase 2 SELECT trial of vopratelimab: Enrollment continues in SELECT, a randomized Phase 2 trial to evaluate vopratelimab in combination with pimivalimab versus pimivalimab alone in immunotherapy naïve, TISvopra biomarker-selected, second line non-small cell lung cancer (NSCLC) patients. The SELECT trial also aims to provide additional important single agent data for pimivalimab in a new biomarker selection paradigm. Jounce is on track to report data from the SELECT trial in 2022.
Gilead Sciences begins Phase 1 clinical trial of GS-1811 (formerly JTX-1811)
The clinical study of GS-1811 (formerly JTX-1811) was initiated by Gilead Sciences. GS-1811, which Jounce discovered and progressed through to IND, is out licensed to Gilead and is the fourth internally developed candidate to enter the clinic.
Corporate Update:
Jigar Raythatha Appointed to the Board of Directors
On September 15th, 2021, Jounce announced the appointment of former chief executive officer of Constellation Pharmaceuticals and former Jounce chief business officer, Jigar Raythatha, to its board of directors.
Third Quarter 2021 Financial Results:
Cash position: As of September 30, 2021, cash, cash equivalents and investments were $249.0 million, compared to $213.2 million as of December 31, 2020. The increase was primarily due to receipt of $90.9 million in net proceeds from the follow-on public offering and sales under Jounce’s at-the-market ("ATM") offering program completed first quarter of 2021 and receipt of a $25.0 million milestone from Gilead in the third quarter of 2021, offset by operating expenses incurred.
License and collaboration revenue: No license or collaboration revenue was recognized in the third quarter of 2021 or 2020.
Research and development expenses: Research and development expenses were $23.3 million for the third quarter of 2021, compared to $18.0 million for the same period in 2020. The increase in research and development expenses was primarily due to increased clinical and regulatory costs for INNATE and SELECT, increased manufacturing activities performed for Jounce’s development programs and payroll and stock-based compensation expense.
General and administrative expenses: General and administrative expenses were $6.9 million for the third quarter of 2021, compared to $7.1 million for the same period in 2020. The decrease in general and administrative expenses was primarily a result of decreased professional fees offset by increases in other administrative costs.
Net loss: Net loss was $30.1 million for the third quarter of 2021, resulting in basic and diluted net loss per share of $0.59. Net loss was $24.9 million for the same period in 2020, resulting in a basic and diluted net loss per share of $0.73. The increase in net loss is attributable to increased operating expenses, the decrease in the net loss per share is attributable to increased number of shares outstanding as compared to the same period in 2020.
Financial Guidance:
Based on its current operating and development plans, Jounce is narrowing its financial guidance on gross cash burn on operating expenses and capital expenditures for the full year 2021 to $100.0 million to $110.0 million. Jounce expects to end fiscal year 2021 with approximately $220.0 million in cash, cash equivalents and investments.
Given the strength of its balance sheet, Jounce continues to expect 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.

About JTX-8064
JTX-8064 is a humanized IgG4 monoclonal antibody designed to specifically bind to Leukocyte Immunoglobulin Like Receptor B2 (LILRB2/ILT4) and block interactions with its ligands. JTX-8064 is the first tumor-associated macrophage candidate developed from Jounce’s Translational Science Platform. Preclinical data presented at the 2020 Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper)’s Annual Meeting and the 2019 and 2021 American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meetings support the development of JTX-8064 as a novel immunotherapy to reprogram immune-suppressive macrophages and enhance anti-tumor immunity. A Phase 1 clinical trial named INNATE (NCT04669899) of JTX-8064 as a monotherapy and in combination with Jounce’s internal anti-PD-1 inhibitor, pimivalimab (formerly JTX-4014) is currently enrolling patients with advanced solid tumors into tumor-specific expansion cohorts.
About Pimivalimab
Pimivalimab (formerly JTX-4014) is a well-characterized fully human IgG4 monoclonal antibody designed to block binding to PD-L1 and PD-L2. Pimivalimab demonstrated a 17% durable overall response rate in a Phase 1 trial of 18 heavily pre-treated PD-(L)1 inhibitor naïve patients, which excluded all tumor types for which PD-(L)1 inhibitors were approved. In this Phase 1 trial, pimivalimab was shown to have an acceptable safety profile. Pimivalimab is currently being assessed in the INNATE Phase 1 trial (NCT04669899) in combination with JTX-8064, a LILRB2 (ILT4) inhibitor. Pimivalimab is also being assessed in the SELECT Phase 2 clinical trial (NCT04549025) in combination with vopratelimab, a clinical-stage monoclonal antibody that binds to and activates ICOS, the Inducible T cell CO-Stimulator, a protein on the surface of certain T cells commonly found in many solid tumors.
About Vopratelimab
Vopratelimab is a clinical-stage monoclonal antibody that binds to and activates ICOS, the Inducible T cell CO-Stimulator, a protein on the surface of certain T cells commonly found in many solid tumors. Vopratelimab is currently being assessed in the SELECT Phase 2 clinical trial (NCT04549025) in combination with Jounce’s internal investigational PD-1 inhibitor, pimivalimab (formerly JTX-4014), compared to pimivalimab alone. The SELECT trial is currently enrolling approximately 75 immunotherapy naïve NSCLC patients who have been pre-selected with the TISvopra predictive biomarker, an 18 gene RNA tumor inflammation signature which predicted the emergence of ICOS hi CD4 T cells and clinical benefit in the ICONIC trial of vopratelimab alone and in combination with a PD-1 inhibitor. SELECT is powered to demonstrate the statistical superiority of the combination of vopratelimab plus pimivalimab compared to pimivalimab.
