PHILADELPHIA and OXFORD, United Kingdom, Feb. 27, 2019 (GLOBE NEWSWIRE) -- Adaptimmune Therapeutics plc (Nasdaq:ADAP), a leader in T-cell therapy to treat cancer, today reported financial results for the fourth quarter and year ended December 31, 2018 and provided a business update.

“2018 was a year of strong delivery across the portfolio with record numbers of patients treated in our clinical trials. We moved through the dose escalation portion of our studies with ADP-A2M4 and ADP-A2M10 and we are now treating patients in the expansion phases for both programs. Our third program, ADP-A2AFP, moved to the second dose cohort at target doses of 1 billion cells. We are very pleased to have observed an acceptable safety profile, thus far, with all three programs, showing no evidence of off-target toxicity or alloreactivity,” said James Noble, Chief Executive Officer. “We are now able to devote our resources to these programs following the successful transition of NY-ESO to GSK.”

“We made equally impressive progress in manufacturing with our in-house facility going from our first ever dose, at the beginning of 2018, to being able to produce target doses for up to 10 patients per month. In the UK, we started up our vector manufacturing that should begin to produce vector later this year. 2019 promises to be a significant year, with data emerging across our portfolio from May onwards. We look forward to reporting clinical data throughout the year,” added James Noble.

Clinical momentum
Initial safety testing is complete in the triple tumor and non-small cell lung cancer (NSCLC) studies with ADP-A2M10, as well as the basket study with ADP-A2M4. All three studies are enrolling and treating patients with up to 10 billion cells in the expansion phases with no pre-determined stagger between dosing required.

In 2018, the Safety Review Committee (SRC) endorsed dose escalation through Cohorts 1, 2, and 3 of these studies, after reviewing safety data from 16 patients treated in the ADP-A2M10 studies and nine patients in the ADP-A2M4 study.

In the hepatocellular carcinoma study with ADP-A2AFP, the SRC endorsed escalation to safety Cohort 2 to treat patients with a target dose of 1 billion cells.

To date, across all four studies, most adverse events have been consistent with those typically experienced by cancer patients undergoing cytotoxic chemotherapy or other cancer immunotherapies with no evidence of alloreactivity or toxicity related to off-target binding.

Building an integrated company
Since the opening of the Navy Yard facility in January 2018, Adaptimmune can now manufacture cells for up to 10 patients per month, and this is scalable to 100 patients per month without significant capital expenditure. Further, an additional 10 patients per month can be treated with cells produced at a third-party vendor HCATs. Both the Navy Yard and HCATs facilities are now able to routinely produce cells to meet target doses across a broad range of solid tumors. This capacity will allow Adaptimmune to service its existing and planned clinical trials.

With respect to vector, Adaptimmune is well supplied as its own vector manufacturing has completed its first engineering run with first production anticipated in 2019, as well as production in place at a third-party vendor. The vendor has already produced vector for ADP-A2M10, ADP-A2M4, ADP-A2AFP, and next generation SPEAR T-cells.

In light of the Company’s increased clinical focus, Rafael Amado assumed the new role of President of R&D last year to bring the clinical and research functions under a single leadership, facilitating alignment and integration of all parts of the R&D structure.

The Company is working with more than 20 active clinical trial sites at leading cancer centers in the US, Canada, and the EU. In Europe, the infrastructure has been tested and has delivered the first doses to patients with additional patients being enrolled in the UK and Spain. Adaptimmune has also reached agreement on an expanded collaboration with MD Anderson Cancer Center (Houston, TX) to further enhance the Company’s translational research capabilities.

While progressing studies with ADP-A2M10, ADP-A2M4, and ADP-A2AFP as well as planning for the next stage of clinical development, including potential registration trials, Adaptimmune continues to progress developing next generation SPEAR T-cells, new targets, other HLAs, and an off-the-shelf product.

Finally, Adaptimmune is funded through to late 2020, based on management’s current estimates, with Total Liquidity1 of $205 million (including cash and cash equivalents of $68 million) at year-end 2018.
