Weighted-average common shares outstanding 10,745,553 shares Basic and diluted, three months ended June 30, 2026
allogeneic gamma delta T cell therapies medical
"developing allogeneic gamma delta T cell therapies for autoimmune diseases and cancer"
in vivo CAR-T medical
"developing a differentiated in vivo CAR-T platform and pipeline"
In vivo CAR‑T is a cancer immunotherapy approach that delivers genetic instructions directly into a patient’s body so their own immune cells are reprogrammed on site to recognize and kill cancer cells, instead of removing and engineering those cells in a lab. For investors, it matters because this method could make CAR‑T treatments faster, cheaper and easier to scale—potentially expanding the market—but it also introduces different safety, manufacturing and regulatory risks that affect commercial viability.
lupus nephritis medical
"data from 22 patients with lupus nephritis (LN) and systemic lupus erythematosus"
Lupus nephritis is a condition in which a person’s immune system attacks the kidneys, causing inflammation and damage to the organs’ filtering function and leading to blood or protein in the urine and, in severe cases, kidney failure. For investors, it defines a specific, medically serious patient group and treatment need: success or failure of therapies, clinical trials, regulatory approvals, and pricing decisions for drugs aimed at this condition can meaningfully change a biotech or pharma company’s revenue prospects — like fixing a costly, central leak in a building that determines the value of the whole property.
metastatic castration-resistant prostate cancer medical
"ADI-212 in metastatic castration-resistant prostate cancer (mCRPC)"
An advanced form of prostate cancer that has spread beyond the prostate to other parts of the body (metastatic) and no longer responds to treatments that lower male hormones designed to starve the tumor (castration-resistant). It matters to investors because it defines a high unmet medical need with limited treatment options, so clinical trial results, new drug approvals, or safety setbacks can sharply change the valuation and prospects of companies working in this area; think of it as a weed that has spread and become resistant to the usual weedkiller.
prostate-specific membrane antigen medical
"cell therapy candidate targeting prostate-specific membrane antigen (PSMA)"
A protein that sits on the surface of prostate cells, often much more abundant on prostate cancer cells, used as a biological “flag” that diagnostic scans and targeted treatments can home in on. Investors care because products that detect or bind this marker—like imaging agents or targeted drugs—can improve diagnosis and therapy, create new revenue streams, and face regulatory milestones that materially affect a company’s value.
Research and development expenses $18.5 million
General and administrative expenses $3.9 million
Net loss $21.4 million
Net loss per share $1.99
Cash, cash equivalents and short-term investments $118.2 million

Advancing in vivo CAR-T platform and pipeline

 

REDWOOD CITY, Calif. – August 5, 2026 – Adicet Bio, Inc. (Nasdaq: ACET), a clinical stage biotechnology company discovering and developing allogeneic gamma delta T cell therapies for autoimmune diseases and cancer, today reported financial results and operational highlights for the second quarter ended June 30, 2026.

 

“At Adicet, we continue to advance prula-cel toward our next important clinical milestone, with a Phase 1 clinical update now expected in the third quarter of 2026. The additional follow-up time will allow us to deliver a more comprehensive and mature dataset, including 22 LN/SLE patients with a minimum of 6 months of follow-up, 13 of whom are expected to have reached at least 12 months of follow-up,” said Chen Schor, President and Chief Executive Officer of Adicet Bio. “We also had productive interactions with the FDA to align on overall clinical design for a potential pivotal trial for prula-cel in LN, further supporting a clear regulatory path forward. Furthermore, we anticipate sharing additional clinical updates for prula-cel in the second half of 2026 in patients with systemic sclerosis.”

 

Mr. Schor continued, “Beyond prula-cel, we are continuing to advance ADI-212 toward Phase 1 alongside our differentiated in vivo CAR-T platform and pipeline targeting hematologic malignancies and solid tumors. With several planned milestones ahead in 2026, including anticipated clinical data readouts in LN and SLE in the third quarter, clinical data in systemic sclerosis in the second half of the year, and an update on our in vivo CAR T platform and pipeline, we look forward to executing our strategic priorities and positioning the company for long-term value creation.”

 


 

 

Second Quarter 2026 and Recent Operational Highlights:

 

Autoimmune diseases

 

Phase 1 prula-cel clinical update in LN and SLE patients expected in 3Q/2026. The Company plans to provide its next clinical update in the third quarter of 2026 for its ongoing Phase 1 clinical trial evaluating prula-cel across multiple autoimmune conditions. The update is expected to include data from 22 patients with LN and SLE (16 LN/ 6 SLE) who will have at least 6 months of follow-up, including 13 patients who are expected to have reached at least 12 months of follow-up. Following alignment with the FDA in November 2025, LN and SLE patients in current and future studies may be dosed with prula-cel in an outpatient setting.

 

Productive FDA interactions to align on overall design for potential pivotal trial design. Based on recent interactions with the FDA, the Company is advancing a potential pivotal trial design in LN and supporting planned start-up activities for a pivotal program anticipated to commence in the second half of 2026, subject to regulatory clearance.

Solid tumor indications

 

Regulatory submission for ADI-212 expected in the third quarter of 2026, with Phase 1 initiation anticipated in the fourth quarter of 2026, pending regulatory clearance.

The program combines membrane tethered IL-12 armoring and CRISPR/Cas9-mediated disruption of subunit 12 of the mediator complex (MED12) designed to improve potency in solid tumors and enable multiple anti-tumor mechanisms within the tumor microenvironment. Adicet expects to submit a regulatory filing for ADI-212 for the treatment of mCRPC in the third quarter of 2026, with initiation of Phase 1 enrollment anticipated in the fourth quarter of 2026, subject to regulatory clearance.

 

In Vivo CAR-T Program and Pipeline
