Adaptimmune Reports Second Quarter 2016 Financial Results

 - Conference call to be held today at 8:00 AM ET (1:00 PM BST) -

PHILADELPHIA and OXFORD, United Kingdom, Aug. 08, 2016 (GLOBE NEWSWIRE) -- Adaptimmune Therapeutics plc (Nasdaq:ADAP) (“Adaptimmune” or the “Company”), a leader in T-cell therapy to treat cancer, today reported financial results for the second quarter ended June 30, 2016.

Recent Corporate and Clinical Highlights:

• Received access to Priority Medicines (PRIME) regulatory support from the European Medicines Agency for NY-ESO SPEAR® (Specific Peptide Enhanced Affinity Receptor) T-cell therapy;
• Received orphan medicinal product designation for SPEAR T-cell therapy targeting NY-ESO for the treatment of soft tissue sarcoma in the European Union from the European Commission;
• Received orphan drug designation for SPEAR T-cell therapy targeting NY-ESO for the treatment of soft tissue sarcoma from the U.S. Food and Drug Administration (FDA);
• Finalized commercial development and supply agreement for Thermo Fisher Scientific’s DynaBeads® CD3/CD28 Cell Therapy System™ for use in manufacturing Adaptimmune’s SPEAR T-cell therapies;
• Announced new preclinical and clinical data at the 2016 American Society of Clinical Oncology (ASCO) meeting, including: data showing that the incidence of cytokine release syndrome appears to be of lower frequency and severity with NY-ESO SPEAR T-cell therapy compared to that reported with CD19 CAR-T therapy; data describing robust clinical responses including a 50 percent response rate (60 percent at the target dose) in synovial sarcoma, and a 91 percent response rate in multiple myeloma; and that Adaptimmune’s extensive preclinical safety package is capable of preclinically validating TCRs with enhanced affinity for target proteins; and
• Expanded synovial sarcoma trials to sites outside of the United States with submissions made to the Medicines and Healthcare Products Regulatory Agency (MHRA) in the United Kingdom, and to Health Canada which has now approved the clinical trial application.

“The last six months were a period of strong progress for Adaptimmune on a number of fronts,” commented James Noble, Adaptimmune’s Chief Executive Officer. “Among our accomplishments, we continued to advance our NY-ESO SPEAR T-cell program toward pivotal studies in sarcoma, received orphan drug and Breakthrough Therapy designation in the U.S. and received both PRIME regulatory eligibility and orphan medicinal product designation in Europe. We also presented important new clinical data at the 2016 ASCO meeting and at our analyst and investor day in April 2016 that continue to differentiate our SPEAR T-cell products from other therapies in the space.”

Mr. Noble continued, “Still, this period has not been without its challenges. As we previously announced, the FDA placed a partial clinical hold on our planned pivotal study of NY-ESO SPEAR T-cell therapy in myxoid round cell liposarcoma and requested additional information prior to trial commencement. We will provide a full response to the FDA shortly. Separately, the initiation of the pivotal study in synovial sarcoma has been delayed until mid-2017. In addition, slower than anticipated enrollment in non-small cell lung cancer (NSCLC) for our MAGE-A10 and NY-ESO SPEAR T-cell therapies has also pushed the timelines for these data readouts into 2017. Notwithstanding these challenges, the breadth and depth of our clinical pipeline mean that, by early 2017, our clinical efforts could involve SPEAR T-cell therapies directed against four separate targets in as many as 10 different tumor types; we anticipate that our data readouts throughout 2017 may validate the targets themselves and, more broadly, our SPEAR T-cell platform in additional solid tumors beyond sarcoma.”

Financial Results for the three-month period ended June 30, 2016

• Cash / liquidity position: As of June 30, 2016, Adaptimmune had $150.9 million of cash and cash equivalents and $55.0 million of short-term deposits representing a total liquidity position¹ of $205.9 million. For the three months ended June 30, 2016, the decrease in cash and cash equivalents was $12.9 million and the decrease in short-term deposits was $7.3 million, representing a decrease in total liquidity position of $20.2 million.
• Revenue: For the three months ended June 30, 2016, revenue was $0.3 million compared to $2.8 million for the three months ended June 30, 2015. This decrease was primarily due to a change in the estimate of the period over which the revenue relating to the GSK Collaboration and License Agreement is being recognized.
• Research and development (“R&D”) expenses: R&D expenses increased to $16.2 million for the three months ended June 30, 2016 from $8.4 million for the three months ended June 30, 2015, primarily due to increased period-over-period costs associated with: ongoing clinical trials of the Company’s NY-ESO and MAGE-A10 SPEAR T-cell therapies; preparation for a study with the Company’s SPEAR T-cell therapy targeting AFP; and personnel expenses for an increased number of employees engaged in R&D.
• General and administrative (“G&A”) expenses: G&A expenses were $6.8 million for the three months ended June 30, 2016 compared to $5.5 million for the three months ended June 30, 2015. The increase was primarily due to increased personnel costs, increased property costs and other costs associated with being a public company, partially offset by a decrease in share-based compensation expenses.
• Net loss: Net loss attributable to holders of the Company’s ordinary shares was $22.1 million for the three months ended June 30, 2016. This equates to $(0.05) per ordinary share or $(0.31) per American Depositary Share.

Financial Guidance

Adaptimmune is reiterating its guidance. For the full year 2016, the Company expects its decrease in total liquidity position to be between $80 and $100 million and expects its total liquidity position at December 31, 2016, including cash, cash equivalents and short term deposits, to be at least $150 million. This guidance excludes the effect of any potential new business development activities.

Pipeline Review
Adaptimmune is providing an update below on each cohort of its clinical pipeline and the timing of anticipated milestones.

NY-ESO SPEAR T-cell Therapy
Synovial sarcoma:
Cohort 1 (high NY-ESO expression, cyclophosphamide + fludarabine) is complete, and was initially reported at the 2015 American Association for Cancer Research (AACR) meeting. Updates on cohorts 2 (low NY-ESO expression, cyclophosphamide + fludarabine) and 3 (cyclophosphamide) will be presented at the 2016 European Society of Medical Oncology (ESMO) meeting. Cohort 4 (modified cyclophosphamide + fludarabine) is on schedule to initiate in 2H 2016.

The Company submitted to the IND its proposed pivotal study in myxoid round cell liposarcoma and received a partial clinical hold notice from the FDA. The notice was received prior to the study being opened at any clinical site. This communication from the FDA was not related to concerns on safety, but rather to the request for additional information on CMC about manufacturing changes introduced in the pivotal program, and information on and modification of some clinical trial design features. The Company intends to submit its full response shortly; the agency will then have 30 days to respond. In addition, enrollment into the pivotal synovial sarcoma study will begin in mid-2017 to allow for the submission of a Special Protocol Assessment requested by FDA and characterization of the revised commercial manufacturing process to be employed in the pivotal studies. If the discussions with the FDA on MRCLS are concluded within the 30-day review window, the Company would expect to initiate the study as planned in Q4 2016/Q1 2017; if it takes longer, then this study will be on a similar timeline to the synovial sarcoma study.

Multiple myeloma:
The 25-patient study with autologous stem cell transplant is complete and has been published (Rapoport; Nat Med, 2015). The Company expects to agree terms for a combination study with a PD-1 receptor inhibitor using cyclophosphamide and fludarabine conditioning in 2016, with initiation of the study occurring in 1H 2017.

Ovarian cancer:
The Company reported data from this six-patient study at the 2016 ASCO meeting showing no objective response in the absence of fludarabine. The Company is evaluating a preconditioning regimen consisting of modified doses of cyclophosphamide and fludarabine and intends to enroll patients in 2H 2016 with this regimen.

Melanoma:
The Company reported data at the 2016 ASCO meeting showing no objective response in the absence of fludarabine in six patients who had progressed after treatment with immune check point inhibitors. The Company is considering a study with a new preconditioning regimen including fludarabine in combination with check point inhibitors in 2017.

Non-small cell lung cancer: 
A study is open and actively screening patients; data are anticipated in 2017. The chemotherapy conditioning for this trial is being modified in an amendment to consist of cyclophosphamide and fludarabine instead of cyclophosphamide alone.

MAGE-A10 SPEAR T-cell Therapy
Non-small cell lung cancer:
A study is open and actively screening patients; data are anticipated in 2017. Chemotherapy conditioning for this trial is being modified in an amendment to consist of cyclophosphamide and fludarabine instead of cyclophosphamide alone.

Bladder, melanoma, and ovarian cancer:
The Company is on track to initiate this study, including a preconditioning regimen of cyclophosphamide and fludarabine, in 2016 with data anticipated in 2017.

AFP SPEAR T-cell Therapy
Hepatocellular cancer:
The investigational new drug application (IND) is open, and the Company anticipates that enrollment will begin in 1H 2017.

MAGE-A4 SPEAR T-cell Therapy
Multiple tumor types:
The Company is on track for an IND submission in 1Q 2017.

Generation 2 TCRs
Multiple tumor types:
The Company is on track to submit INDs from 2017 onwards.
