"Our commitment to delivering best-in-class gamma delta 1 T cell therapies for patients battling autoimmune diseases and cancer is reflected in the expansion of our clinical pipeline in the third quarter. We are now investigating ADI-001 across six autoimmune indications to provide potentially transformative curative therapies for these debilitating diseases. Additionally, in the fourth quarter we plan to open enrollment for our Phase 1 trial of ADI-270 in patients with metastatic/advanced clear cell renal cell carcinoma (ccRCC), our first gamma delta 1 CAR T cell therapy for solid tumors. This progress highlights the broad and important potential applications of our gamma delta platform," said Chen Schor, President and Chief Executive Officer. "Looking ahead, we anticipate advancing enrollment in these trials and expect to share preliminary clinical data from both lupus nephritis with ADI-001 and metastatic/advanced ccRCC with ADI-270 in the first half of 2025."

Third Quarter 2024 and Recent Operational Highlights:

Autoimmune diseases

Activated clinical sites in ADI-001 Phase 1 trial in autoimmune diseases. In September 2024, Adicet activated sites for its Phase 1 clinical trial of ADI-001 in autoimmune diseases. The company is exploring the potential of ADI-001 across six indications including LN, systemic lupus erythematosus (SLE), systemic sclerosis (SSc), idiopathic inflammatory myopathy (IIM), stiff person syndrome (SPS) and anti-neutrophil cytoplasmic autoantibody (ANCA) associated vasculitis (AAV). The Company opened enrollment for patients with LN in 4Q24 and expects to initiate enrollment for patients with SLE, SSc, IIM, and SPS in 1Q25, and for patients with AAV in 2H25. The Company plans to report preliminary clinical data from the Phase 1 clinical study of ADI-001 in LN in 1H25, and for other autoimmune diseases in 2H25, subject to study site initiation and patient enrollment.
FDA clearance of IND amendment to evaluate ADI-001 in IIM and SPS. In October 2024, Adicet announced that the U.S. Food and Drug Administration (FDA) cleared the Company’s Investigational New Drug (IND) amendment application to evaluate ADI-001 in IIM and SPS as part of the Phase 1 clinical trial in autoimmune diseases.
Presented ADI-001 clinical biomarker data demonstrating robust tissue trafficking and complete B cell depletion in secondary lymphoid tissue. In September 2024, Adicet presented clinical biomarker data from the Phase 1 GLEAN trial of ADI-001 at the 9th Annual CAR-TCR Summit. The data demonstrated robust tissue trafficking resulting in high levels of ADI-001, significant chimeric antigen receptor (CAR) T cell activation, and complete CD19+ B cell depletion in secondary lymphoid tissue. These findings further reinforce ADI-001’s potential as a best-in-class allogeneic cell therapy for autoimmune diseases.
Presentation of ADI-001 clinical data at the American College of Rheumatology (ACR) Convergence 2024. In November 2024, Adicet will present an oral abstract highlighting previously presented ADI-001 clinical biomarker data at ACR Convergence 2024 taking place November 14-19 in Washington, D.C.
Hematologic malignancies and solid tumor indications

ADI-270 Fast Track Designation in metastatic/ advanced ccRCC. In July 2024, Adicet announced that the FDA granted ADI-270 Fast Track Designation for the potential treatment of patients with metastatic/advanced ccRCC who have been treated with an immune checkpoint inhibitor and a vascular endothelial growth factor inhibitor.
Presented ADI-270 data at the American Society of Gene & Cell Therapy’s (ASGCT) (Free ASGCT Whitepaper) 2024 Advancing Gene + Cell Therapies for Cancer conference. In October 2024, Adicet presented ADI-270 data in an oral presentation at the ASGCT (Free ASGCT Whitepaper) 2024 Advancing Gene and Cell Therapies for Cancer conference.
Corporate Updates

Appointed Lloyd Klickstein, M.D., Ph.D. to Board of Directors. In August 2024, Adicet appointed Dr. Lloyd Klickstein to its Board of Directors. Dr. Klickstein brings over two decades of leadership experience in the biopharmaceutical industry and biomedical research, and expertise in rheumatology and immunology to Adicet. Dr. Klickstein currently serves as President and Chief Executive Officer of Koslapp Therapeutics, Inc. and is the Board Chair of the Lupus Foundation of New England.

About UNITE

ITI’s investigational UNITE platform, UNiversal Intracellular Targeted Expression, leverages the ability to engineer chimeric proteins, directing antigen presenting cells to present antigens to the immune system through a targeted pathway and driving a robust immune response. UNITE vaccines are distinct in that they combine two components: nucleic acid constructs that encode a specific antigen and an endogenous Lysosomal Associated Membrane Protein (LAMP-1) sequence. The UNITE platform harnesses LAMP-1 as a means of presenting the vaccine target to the immune system, resulting in antibody production, inflammatory cytokine release, and establishing critical immunological memory, something that other vaccine approaches commonly lack. This approach could put UNITE technology at the crossroads of immunotherapies in multiple indications, including cancer, human allergy, animal health, and infectious disease. Preclinical data is currently being developed to explore whether LAMP-1 nucleic acid constructs may amplify and activate the immune response in highly immunogenic tumor types and used to create immune responses in tumor types that otherwise do not provoke an immune response.

Title: Identifying a composite signature for predicting immune-related adverse events in advanced melanoma patients treated with immune checkpoint blockade
Date & time: Saturday, November 9 | 9:00 AM to 8:30 PM CST
Presenter: Michael Goldberg, PhD, BostonGene

Using flow cytometry and bulk RNA-seq to analyze blood cells of advanced melanoma patients collected before immune checkpoint blockade (ICB) treatment, we examined if the occurrence of immune-related adverse events (irAEs), severe and potentially fatal side effects of ICB, can be predicted. irAE signatures were constructed and used to detect distinct cellular and gene expression patterns among patients who developed severe irAEs post-ICB treatment. These signatures can potentially identify patients likely to develop irAEs, enabling timely mitigation to improve patient outcomes.

Abstract number: 170
Title: Identifying novel targets for antibody-drug conjugates in sarcomas using RNA sequencing
Date & time: Saturday, November 9 | 9:00 AM to 8:30 PM CST
Presenter: Vladimir Kushnarev, MD, PhD, BostonGene

RNA sequencing uncovered the expression landscape of potential antibody-drug conjugate (ADC) targets in sarcomas, particularly those lowly expressed in normal tissues. The combined expression of ADC targets with tertiary lymphoid structure and immune checkpoint gene signatures also depicts the immune landscape of sarcomas and can guide the development of immunotherapy approaches. Our findings revealed many genes that are precluded from existing clinical trials, underscoring the need to advance clinical trials and precision oncology in sarcoma therapies that prioritize safety and efficacy.

"We have made great progress with our PRMT5 development program, including positive data from the TNG462 phase 1/2 clinical trial that showcase the best-in-class potential of TNG462 in multiple tumor types, including pancreatic and non-small cell lung cancers (NSCLC). Based on these early data, we are advancing TNG462 into trials with multiple targeted and standard of care combinations, including two RAS(ON) tri-complex inhibitors from Revolution Medicines. Given that nearly all MTAP-deleted pancreatic cancer has a co-occurring RAS mutation, we believe this could be a powerful approach to changing the treatment landscape for this challenging cancer," said Barbara Weber, M.D., President and Chief Executive Officer of Tango Therapeutics. "As part of the expanded capabilities needed to rapidly move TNG462 development forward, Dr. Maeve Waldron-Lynch, M.D. is joining Tango as Senior Vice President, Head of Clinical Development. Dr. Waldron-Lynch has extensive late-stage oncology clinical development and regulatory experience and will be invaluable as we prepare to advance TNG462 to registration."

In a separate press release issued earlier today, Tango Therapeutics provided an update on its ongoing PRMT5 clinical development program:

Data from the ongoing phase 1/2 clinical trial of TNG462, a potentially best-in-class MTA-cooperative PRMT5 inhibitor, demonstrate clinical activity across multiple tumor types, including NSCLC and pancreatic cancer. Of note, this includes an ORR of 43% in cholangiocarcinoma (n=7). Substantive durability and a good safety and tolerability profile also were observed in this ongoing trial. The next clinical update is expected in 2025.
The Company plans to initiate multiple targeted and standard of care combinations with TNG462 including RAS(ON) multi-selective and RAS(ON) G12D-selective inhibitors (Revolution Medicines), osimertinib (AstraZeneca) and pembrolizumab (Merck). These studies are expected to begin enrolling in 1H 2025.
TNG908, an MTA-cooperative brain-penetrant PRMT5 inhibitor, is clinically active and well-tolerated across non-CNS cancers in the phase 1/2 clinical trial. In particular, there were a total of nine evaluable pancreatic cancer patients, two with partial responses (ORR 22%) and five with stable disease as best response to date. The five ongoing pancreatic cancer patients have been on study for an average of 24 weeks, the longest for 72 weeks.
TNG908 did not demonstrate activity in glioblastoma (n=23 at active doses) likely because CNS exposure did not meet the required exposure threshold for clinical efficacy.
TNG908 enrollment is being stopped to allow full resourcing of TNG462 as a potential best-in-class molecule. In particular, the notably longer time on treatment observed – 24 weeks and still increasing for TNG462 versus 16 weeks for TNG908 – the superior target coverage, and the safety and tolerability profile all support selection of TNG462 for further development.
TNG456 is a next-generation brain-penetrant MTA-cooperative PRMT5 inhibitor that is 55X selective for MTAP deletion with 20 nM potency. Preclinical studies suggest TNG456 central nervous system exposure has the potential to be sufficient for meaningful efficacy in glioblastoma and brain metastases.
The Company expects to begin enrolling patients in the planned phase 1/2 trial during 1H 2025.
Business Highlights

Clinical collaboration with Revolution Medicines

In November 2024, the Company entered into a clinical collaboration with Revolution Medicines to evaluate the efficacy and safety of TNG462 in combination with RMC-6236, a RAS(ON) multi-selective inhibitor, and with RMC-9805, a RAS(ON) G12D-selective inhibitor.
The agreement provides that Revolution Medicines will supply RMC-6236 and RMC-9805 to Tango and that Tango will be the sponsor of any combination trials. Each company will retain commercial rights to their respective compounds and the agreement is mutually non-exclusive.
TNG260, a first-in-class, highly selective CoREST complex inhibitor

The TNG260 phase 1/2 clinical trial is ongoing, evaluating safety, pharmacokinetics, pharmacodynamics and efficacy of TNG260 in combination with pembrolizumab in patients with locally advanced or metastatic solid tumors with an STK11 loss-of-function mutation. To date, safety, tolerability and pharmacokinetic profiles are favorable.
STK11 mutations occur in approximately 15% of non-small cell lung, 15% of cervical, 10% of carcinoma of unknown primary, 5% of breast and 3% of pancreatic cancers.
Upcoming Milestones

TNG462 clinical data update expected in 2025
TNG462 combination trial enrollment expected to begin 1H 2025
TNG456 phase 1/2 trial enrollment expected to begin 1H 2025
TNG260 clinical data expected in 2025

Financial Results

As of September 30, 2024, the Company held $293.3 million in cash, cash equivalents and marketable securities, which the Company expects to be sufficient to fund operations into the third quarter of 2026, including for additional planned TNG462 and TNG456 clinical trials.

Collaboration revenue was $11.6 million for the three months ended September 30, 2024, compared to $10.7 million for the same period in 2023, and $25.9 million for the nine months ended September 30, 2024 compared to $26.1 million for the same period in 2023. Collaboration revenue increased due to changes to estimated costs expected to be incurred under the collaboration during the three months ended September 30, 2024.

License revenue was $0 and $12.1 million for the three and nine months ended September 30, 2024, respectively, compared to $0 and $5.0 million for the three and nine months ended September 30, 2023, respectively. The year-to-date increase is primarily due to licensing a drug discovery program to Gilead for $12.0 million during the second quarter of 2024 as compared to Gilead licensing a program for $5.0 million during the second quarter of 2023.

Research and development expenses were $33.3 million for the three months ended September 30, 2024, compared to $27.1 million for the same period in 2023, and $110.0 million for the nine months ended September 30, 2024 compared to $83.9 million for the same period in 2023. The change is due to increased spend related to the advancement of TNG462, preclinical programs and personnel-related costs to support our research and development activities.

General and administrative expenses were $11.2 million for the three months ended September 30, 2024, compared to $9.2 million for the same period in 2023, and $32.7 million for the nine months ended September 30, 2024 compared to $26.4 million for the same period in 2023. The change was primarily due to increases in personnel-related costs.

Net loss for the three months ended September 30, 2024 was $29.2 million, or $0.27 per share, compared to a net loss of $22.3 million, or $0.23 per share, in the same period in 2023. Net loss for the nine months ended September 30, 2024 was $92.6 million, or $0.85 per share, compared to a net loss of $71.0 million, or $0.78 per share, in the same period in 2023.
