LONDON, April 04, 2024 (GLOBE NEWSWIRE) -- Achilles Therapeutics plc (NASDAQ: ACHL), a clinical-stage biopharmaceutical company developing AI-powered precision T cell therapies targeting clonal neoantigens to treat solid tumors, today announced interim Phase I/IIa data on the use of clonal neoantigen reactive T cells (cNeT) from the CHIRON study in advanced unresectable or metastatic non-small cell lung cancer (NSCLC) and the THETIS study in recurrent or metastatic malignant melanoma. The update includes data from 18 patients across CHIRON (n=12) and THETIS (n=6) dosed since the previous interim update in December 2022, with two CHIRON patients and one THETIS patient having received enhanced chemo-conditioning and IL-2 dosing aligned to standard tumor infiltrating lymphocyte (TIL) therapy (enhanced host conditioning) in a new Cohort C. This new Cohort C will allow the impact of enhanced host conditioning on cNeT engraftment and persistence beyond 28 days to be evaluated.

The article, entitled Breaking the performance ceiling for neoantigen immunogenicity prediction , makes the case that the efficient and accurate selection of immunogenic neoantigens is a critical determinant in neoantigen-based personalized tumor therapies.

LONDON, Sept. 22, 2023 (GLOBE NEWSWIRE) -- Achilles Therapeutics plc (NASDAQ: ACHL), a clinical-stage biopharmaceutical company developing AI-powered precision T cell therapies targeting clonal neoantigens to treat solid tumors, today disclosed that the Company received notice on September 20, 2023 from the Nasdaq Stock Market LLC (“Nasdaq”) that the Company is not currently in compliance with the $1.00 minimum bid price requirement for continued listing of the Company’s American Depositary Shares (the “ADS”) on the Nasdaq Global Select Market, as set forth in Nasdaq Listing Rule 5450(a)(1) (the “Minimum Bid Price Requirement”).

NEW YORK, Sept. 20, 2023 /PRNewswire/ -- More than 30 million people in the United States suffer with a rare disease; most of them are receiving no current treatment. Supporting the development and evaluation of new treatments, particularly for rare diseases, is a key priority for the U.S. Food & Drug Administration. As part of that process, the agency can grant Orphan Drug Designation (ODD) to a drug or biological product being developed to prevent, diagnose or treat a rare disease or condition. This designation is intended to spark innovation among biotech companies that are developing treatments for these patient populations, which by definition affect fewer than 200,000 people in the U.S., by providing incentives such as tax credits, user-fee exemptions and up to seven years of market exclusivity after FDA approval. Last month, Genprex Inc. (NASDAQ: GNPX) (Profile) was granted FDA orphan drug designation for its REQORSA(R) immunogene therapy in development for the treatment of small cell lung cancer (SCLC). The Phase 1/2 clinical trial, expected to dose the first patient in the fourth quarter of 2023, uses a combination of REQORSA and Genentech Inc.'s Tecentriq(R) as maintenance therapy in patients with extensive stage small cell lung cancer ("ES-SCLC") who did not develop tumor progression after receiving Tecentriq and chemotherapy as initial standard treatment. Genprex joins other companies — including Roche Holding AG ADR (OTCQX: RHHBY), Jazz Pharmaceuticals PLC (NASDAQ: JAZZ), ALX Oncology Holdings Inc. (NASDAQ: ALXO) and Achilles Therapeutics PLC (NASDAQ: ACHL) — that have been granted ODD status or may seek ODD status as they work to develop treatments for rare diseases.
