PHILADELPHIA and OXFORD, U.K., Aug. 03, 2017 (GLOBE NEWSWIRE) -- Adaptimmune Therapeutics plc (Nasdaq:ADAP), a leader in T-cell therapy to treat cancer, today reported financial results and business updates for the quarter ended June 30, 2017.

“This was a very exciting quarter for Adaptimmune,” commented James Noble, Adaptimmune’s Chief Executive Officer. “We made significant progress clinically by initiating our first trials with two proprietary programs, MAGE-A4 and AFP, and also initiated our first combination study with NY‑ESO. We presented data in an oral presentation at ASCO, showing responses in all four cohorts in our NY-ESO synovial sarcoma study. And, importantly, we also extended our cash runway to late 2019, well past the expected data points on all three of our proprietary programs. We are now focused on delivering clinical data across multiple tumor types as we move through the second half of this year and into 2018. We are also very encouraged by FDA’s Oncology Drug Advisory Committee’s recent unanimous endorsement of Novartis’s anti-CD19 CAR-T therapy, with which we share common manufacturing process elements, as this is a positive review of the first gene therapy cell product in the US.”

Recent Corporate Highlights:

• Completed April 2017 registered direct offering to Matrix Capital Management Company, LP, which combined with March 2017 public offering, raised total net proceeds of $103.2 million; 
• Initiated AFP SPEAR T-cell therapy clinical trial in hepatocellular carcinoma;
• Initiated MAGE-A4 SPEAR T-cell therapy clinical trial in urothelial (bladder), melanoma, head & neck, ovarian, non-small cell lung cancer (NSCLC), esophageal, and gastric cancers;
• Initiated clinical trial of NY-ESO SPEAR T‑cells in combination with KEYTRUDA® (pembrolizumab), an anti-PD-1 inhibitor marketed by Merck & Co., Inc., Kenilworth, NJ, USA (known as MSD outside the US and Canada), in patients with multiple myeloma;
• Presented data during an oral presentation at ASCO from ongoing study of NY-ESO SPEAR T-cells in synovial sarcoma indicating that:
  • Initial anti-tumor activity observed in all ongoing cohorts including low expressors of NY‑ESO
  • Fludarabine appears to be an important component of the lymphodepletion regimen
  • NY-ESO continues to be generally well-tolerated:
    • All reported events of cytokine release syndrome resolved, and the majority of events were Grade 1 or 2
    • There were no reported events of seizure, cerebral edema, or encephalopathy
  • Survival and response data in Cohort 1 (non-modified fludarabine / cyclophosphamide [“Flu/Cy”] lymphodepletion regimen) continue to be promising (data cutoff March 30, 2017):
    • Of the 12 patients treated, 5 remain alive with a median predicted overall survival of 120 weeks (~28 months), and 6 responses were observed
    • 10 patients received the target dose of 1 billion transduced NY‑ESO SPEAR T-cells, and the median predicted overall survival for those patients is 159 weeks (~37 months)

Financial Results for the Three Months ended June 30, 2017

• Cash / liquidity position: As of June 30, 2017, Adaptimmune had cash and cash equivalents of $122.0 million and Total Liquidity¹ of $220.0 million.
• Revenue: Revenue represents the upfront and milestone payments, which are recognized over the period the Company delivers services to GSK. Revenue for the three months ended June 30, 2017 was $3.5 million. The increase in revenue is due to the revenue in the three months ended June 30, 2016 being adversely impacted by a change in estimate of the period over which revenue is being recognized, which reduced revenue in that quarter by $2.8 million.
• Research and development (“R&D”) expenses: R&D expenses for the three months ended June 30, 2017 were $19.6 million, compared to $16.9 million for the same period of 2016. The increase was primarily due to increased costs associated with clinical trials; costs of developing manufacturing capability in the Company’s U.S. facility and increased personnel expenses.
• General and administrative (“G&A”) expenses: G&A expenses for the three months ended June 30, 2017 were $7.7 million, compared to $6.2 million for the same period of 2016. The increase was primarily due to increased personnel costs consistent with our planned growth.
• Net loss: Net loss attributable to holders of the Company’s ordinary shares for the three months ended June 30, 2017 was $20.2 million ($(0.04) per ordinary share or $(0.24) per American Depositary Share (“ADS”) compared to $22.1 million ($(0.05) per ordinary share or $(0.31) per ADS) in the same period of 2016.

Total Liquidity (a non-GAAP financial measure)
Total Liquidity is the total of cash and cash equivalents, short-term deposits and marketable securities. Each of these components appears in the Consolidated Balance Sheet. The U.S. GAAP financial measure most directly comparable to Total Liquidity is cash and cash equivalents as reported in the Consolidated Financial Statements, which reconciles to Total Liquidity as follows:

The Company believes that the presentation of Total Liquidity provides useful information to investors because management reviews Total Liquidity as part of its management of overall liquidity, financial flexibility, capital structure and leverage.

(1) Certain costs have been reclassified in prior periods to conform to the current period presentation.  The net effect is to reduce G&A and increase R&D by $637,000 and $1,225,000 in the three and six months ended June 30, 2016, respectively.

(2) The effect of 67,082,914 and 46,127,274 share options, which are potentially dilutive equity instruments, have been excluded from the diluted loss per share calculation for the three months ended June 30, 2017 and 2016, respectively, because they would have an antidilutive effect on the loss per share for the period.
