o Excellent toxicity results for PS110 and PS278-05 in Alzheimer's - CK1d

o HUPO Science and Technology Award for TMT®

o Strong growth in revenues expected in 2015

Following the growth in licensing, services and TMT® sales in 2013 we have seen further underlying strengthening in our core technologies and services in the first half of 2014. Inevitably, several of the contracts we were expecting earlier in the year have experienced delays in commencement and as such because of their size it is difficult to be precise when the full revenue contributions will be reflected. We are delighted that the recently announced $2 million assay development contract signals the expansion in our orders and that the scale and number of such contracts is growing steadily.

TMT® reagents continue to show rapid growth and increase their market share as they continue to be adopted in mainstream systems biology. The 10-protein MCI/AD panel announced in July opens up entirely new horizons in patient stratification and gives the opportunity to develop and outlicense a simple blood test with several interested parties already engaged. Completion of the dossier on our CK1d compounds in AD including excellent recent toxicity data will enhance our ongoing efforts to secure a pharma licensee for completion of pre-clinical studies. This will provide considerable signature and milestone fees and royalty payments.

Having established Proteome Sciences at the forefront of proteomics with the development of SysQuant® and TMT® calibrator workflows over the last two years, we are ideally positioned to capitalise through our three core activities. We expect to see strong growth in orders and that performance should continue in 2015.

Chairman's Update

Our science and main business activities have made considerable progress in 2014.

In the period under review 14 client projects were undertaken and we anticipate a number of follow-on studies to be signed before the end of the year. We are particularly pleased that PS Biomarker Services has been selected to develop new diagnostic assays for Alzheimer's disease in the context of treatment with LMTX a drug that affects tau tangles in the brain. We are seeing high levels of interest in our SysQuant and TMT-MS3 biomarker discovery workflows as well as for TMTcalibrator which can be combined with any of our discovery workflows to increase the numbers of biomarkers found in body fluids.

TMT products continue to increase their presence in the marketplace and the introduction of TMT® 10-plex reagents into the Thermo Scientific 2014 catalogue has allowed TMT® to become the market leader.

We have also made substantial progress with our internal research programs with several key publications this year. The original SysQuant® workflow analysis of pancreatic cancer was published in PLOS ONE in January and we filed new patents covering the novel biomarkers and drug targets discovered. A study validating our discovery in 2013 of Tubulin b-III as a marker of drug resistant liver cancer was published in July.

Also in July a breakthrough publication in Alzheimer's and Dementia: Journal of the Alzheimer's Association disclosed that a 10-protein panel in blood predicted the progression from mild cognitive impairment to Alzheimer's disease with 87% accuracy and made global headline news.

We have recently completed analysis of the effects of our patented CK1d inhibitors in a model of human tauopathies. Results confirm that they have a wide mode of action with beneficial effects on a number of key aspects of Alzheimer's disease pathology.

The 10th Siena Meeting "From Genome to Proteome: 20 years of Proteomics" at the end of August is the leading global proteomics workshop for proteomics and provided an extensive backcloth as to the current status of developments in protein and peptide biomarkers and what was expected over the next five years.

It is pleasing to report that many of the themes and applications being projected to be undertaken are workflows and applications that Proteome Sciences has completed over the last two years and a number of these were presented at Siena. We saw no new technology that would undermine our technology platform and the meeting endorsed Proteome Sciences' position at the forefront of proteomics.

Perhaps the most significant factor highlighting the importance of proteomics for personalised medicine was the publication in Nature in May 2014 of the Protein Atlas. It provides an A to Z of proteins which, for the first time, will allow genomics researchers to complement their research with information on changes in protein and peptide expressions that cannot be obtained through genomics but that are central to personalised medicine. Since the sequence of the human genome, genomics has driven the growth and value of the pharmaceutical industry over the last 10-15 years. Proteins and proteomics can play a much larger and more long-lasting role and may prove to be the key value driver for drug development, diagnosis and patient management.

The combination of these developments and the accelerating drive for better drugs and diagnostics for personalised medicine provide a great backcloth for revenue growth in our business and prospects.

Revenue

First half revenue from three main areas totalled £0.78 (2013: £0.89m). Licenses/Sales/Services revenues totalled £0.71m (2013: £0.75m), Grant Services were £0.07m (2013: £0.13m) and TMT® reagent sales increased 98% against the corresponding period in 2013. A more significant contribution is expected in the second half, in particular from Licenses, Sales and Services that should result in a considerable improvement for the full year with continued strong growth from TMT®.

Alzheimer's disease

Publication of the long awaited results of the 1000 patient study, co-authored with King's College London, in Alzheimer's and Dementia: Journal of the Alzheimer's Association achieved a high level of media attention globally.

Blood samples from three international studies of 1,148 individuals (476 with AD; 220 with mild cognitive impairment (MCI) and 452 elderly controls without dementia) were analysed for 26 proteins previously shown to be associated with Alzheimer's disease. A sub-group of 476 individuals across all three groups also had an MRI brain scan.

Of the 26 proteins measured, 16 were strongly associated with brain shrinkage in either MCI or AD and could be useful in assessing the extent of damage without needing to repeatedly take brain scans. A second series of tests was run that, based on the levels of just 10 blood proteins, could predict with 87% accuracy which of the individuals with MCI would go on to develop Alzheimer's.

How does this affect drug development and treatment?

Being able to predict with a high level of accuracy whether someone with early symptoms of memory loss or MCI will or will not develop Alzheimer's within 12-18 months is important for a number of reasons:

· Currently only around 20-30% of patients recruited into drug trials will progress to AD in 12 to 18 months

· A large number of patients are needed and they have to be followed for a long time

· There is more probability without the use of this new test that patients receiving the placebo will perform just as well as those on the drug, even though the drug may be working in the rapidly converting population

· The window between MCI and AD currently offers the best chance for successful treatment. This is the key target time for the drug to act and to administer it to the patient

· Earlier and accurate identification of MCI should lead to faster and better patient outcomes

What is the next stage?

A simple blood test could help identify patients at a much earlier stage to be enrolled in new trials and hopefully develop treatments which could prevent the progression of the disease. The next step will be to further validate the findings in larger sample sets to see if the accuracy can be improved and to reduce the risk of misdiagnosis to develop a reliable test suitable for use by doctors. That process will get underway from samples available from the UK and Europe in biobanks.

How does Proteome Sciences monetise these results?

The potential for AD diagnostic and prognostic tests in blood is considerable with industry estimates of around $1-2 billion per annum.

There are three main applications:

· Patient stratification for clinical trials

· Research assays for drug development/testing

· Clinical diagnostics

The first two applications should be available in 2015 with the clinical diagnostic to be developed in the next two to five years. The process to commence commercial discussions to outlicense diagnostic applications has already started with interested parties.

AD - CK1d

We continue to make very good progress with our CK1d programme. Smart biological testing to determine the effects that the changes have on target safety, selectivity and activity, is an important step to optimise compounds prior to testing in humans. The SysQuant® study revealed that our CK1d compounds have modified certain key cell pathways linked to amyloid processing, oxidative phosphorylation and energy production and these have reduced tau damage. We are delighted to report that the results of a toxicity study just received confirm that PS110 and PS278-05 have come through with excellent safety characteristics. After successful in vivo trials, we can confirm that the compounds can be delivered orally, have good stability and absorption, are long-lasting with excellent toxicity results and, most importantly, reduce amyloid aggregation and tau tangles. The last two rounds of testing lock in incremental value for the outlicensing processing.

With this additional data available, we will shortly complete the CK1d dossier and move to the next stage of marketing to progress the outlicensing programme with pharmaceutical companies following our presentations at the Alzheimer's Association International Conference (AAIC) in July. It was timely news that Astra Zeneca (AZ) announced that it had partnered with Lilly on a BACE inhibitor AZD 3293 in Phase 1 trials with Lilly paying $500 million to AZ (including milestones) and will also cover half of the costs of future clinical trials for joint ownership of the programme. This is a good benchmark of the current value of a drug for Alzheimer's disease.

 $2m Biomarker Services and assay development contract

PS Biomarker Services™ Division (PS) has been selected to develop an AD blood test for Genting TauRx Diagnostics (GTD). The project will involve PS analyzing blood samples from patients enrolled in a phase 3 trial of the experimental Alzheimer's drug LMTX, targeting the tau pathway, developed by TauRx Pharmaceuticals Ltd, an affiliate of GTD.

Key to selecting PS was its established portfolio of blood biomarkers for predicting the progression of patients with Mild Cognitive Impairment and Alzheimer's disease along with its proprietary TMTcalibrator plasma proteomics workflows. The study will involve blood proteomic profiling of approximately 1000 individuals and construction of a targeted protein panel for AD diagnosis and monitoring of treatment efficacy.

Under the terms of the agreement announced on 25th September, Proteome Sciences is to receive research fees totaling $2 million including upfront and milestone payments. GTD will receive a license to PS's existing blood biomarkers for AD and the companies will share commercialisation rights to the diagnostic assays.

TMT®

The profile of TMT® continues to rise, having already become the global market leader in 2014. The strong revenue growth in the first half reflected the general introduction of TMT® 10-plex in January 2014 and this was helped by the considerable favourable exposure received at the American Society of Mass Spectrometry meeting (ASMS) in June. We were also delighted that TMT® isobaric mass tags will receive the prestigious accolade of the HUPO (Human Proteome Organisation) Science and Technology Award at the forthcoming congress in Madrid. This should further increase the visibility and penetration of TMT® into mainstream systems biology and will be assisted in 2015 by the development of higher plexing-rates.

SysQuant®

Much of our focus in 2014 has been directed at expanding and developing our SysQuant® and TMT® calibrator workflows in new disease areas and applications. SysQuant® provides a helicopter view over cell signaling pathways and allows Proteome Sciences to measure changes in phosphorylation and to track the expression of important drug targets and signaling pathways. It is a powerful proprietary workflow combining our TMT® reagents with high resolution mass spectrometry that can accurately map over 23,000 of the switches (phosphorylation sites) and more than 7,000 individual proteins regulating cell signaling pathways in up to 10 samples in a single run. When the patient sample is analysed, various parameters are measured to predict the most relevant drug targets and potential causes of recurrence of tumours highlighting which mechanisms might be used to elude anti-cancer therapies. This will allow doctors to quickly focus on the right resources for each patient and should dramatically improve the efficacy of treatment but, most importantly, without increasing the overall cost. These workflows are particularly applicable to cancer, but will work equally well in all the major disease areas.

The first SysQuant® study published was in pancreatic cancer in PLOS ONE in March 2014, in which we analysed the tumours of 12 patients with collaborators at King's College Hospital, London. In this study we reported a total of 6,284 unique phosphorylation sites and 2,101 individual proteins. We were able to identify multiple cancer-generating pathways that were activated, with some pathways highly active in all 12 patients whilst others were only found in a subset of the patients. In each case we were able to identify unique combinations of targets for existing anti-cancer drugs which could potentially have provided a superior treatment outcome.

We subsequently presented SysQuant® for the first time in a CNS application at the Alzheimer's Association International Conference in Copenhagen in July where we obtained 100,000 peptide IDs and over 22,000 phosphopeptides from a single experiment. Several key cell signaling pathways were identified and these changes supported a much wider mode of action for our CK1d compounds in preventing tau mediated damage.

The combination of having successfully completed SysQuant® commercial and pilot work earlier in the year and the high profile and attention it is receiving at meetings and in publications has built a substantial volume of customer interest and orders that should be strongly reflected in increased revenues in 2015.

Management

With the impending retirement of James Malthouse, the Finance Director, in November after 20 years with the company, we are pleased to announce the appointment of Mr. Geoffrey Ellis as Finance Director with effect from 1st October. Mr. Ellis is a chartered accountant with over 30 years' experience in a range of senior financial, operational, sales and business development roles. He spent 15 years at Walt Disney where he was Chief Financial Officer of the Network of Disney Channels in EMEA and Managing Director of Disney Chanel Scandinavia, Middle East and Emerging Markets.

In addition to a strong financial background, he brings considerable international sales, marketing and licensing expertise and a key part of his role will be managing and expanding our commercial sales and marketing activities in USA and Europe.

James Malthouse will remain as a director of the company until his retirement on 30th November, 2014.

An in-house patent counsel, a specialist in biomarkers, has been recruited to bring the management of our 600+ patent portfolio in-house. This non-Board appointment will make the management of the patent portfolio far more efficient and provide a considerable saving in the level of patent costs. These two appointments are intended to distribute parts of Dr. Ian Pike's responsibilities in order to free up more time for him to focus on the rapid growth in contracts and the key interface of our technology development, workflows and applications with our customers.

Financial Review

Financial Performance

Revenue for the six month period ended 30th June, 2014 totalled £0.78m (2013: £0.89m). In the breakdown of revenue, Licenses/Sales/Services were £0.71m (2013: £0.75m), Grant Services were £0.07m (2013: £0.13m) and TMT® reagent sales increased 98% over the period. Due to timing issues, larger contributions are expected in the second half of 2013 from Licenses/Sales/Services. The loss before tax in the first six months was £2.10m (2013: £1.90m).

Costs and available cash

Costs at £2.46m (2013: £2.34m) were running marginally ahead of the figure reported in 2013. After the R&D tax credit, the loss after taxation for the period reduced to £1.84m (2013: £1.66m). Cash at 30th June was £3.47m (31 December 2013: £0.60m).

Outlook

With no new technology apparent at the 10th Siena meeting to rival its technology platform and position at the forefront of proteomics, we believe that Proteome Sciences is ideally placed to maximise revenue from its three core divisions.

The early focus and development of our SysQuant® and TMTcalibrator workflows give Proteome Sciences a unique advantage and position in personalised medicine that has been recognised and has quickly gained considerable external traction. This is reflected in the volume and variety of prospective customer contracts that have been pro-actively received and is increasingly reflected in rapidly expanding order book and customer enquiries for PS Biomarker Services™.

Our TMT® reagents continue to show rapid growth and their market penetration into mainstream systems biology will be extended by the HUPO Science and Technology Award and the introduction of higher plexing levels in 2015.

The excellent toxicity results for PS110 and PS278-05 provide the last elements required to complete the dossier for the CK1d programme in Alzheimer's to move the outlicensing strategy to its final stages and to secure a licence with a pharmaceutical company which should provide considerable signature fees, milestones and royalty payments. We are actively engaged to obtain the external resources necessary from key stakeholders to accelerate the development of the clinical diagnostic for MCI/AD detection from the 10-protein panel in blood and in the meantime we are actively promoting the access to our biomarker panel for research applications to customers to undertake patient stratification and obtain assays for drug development and testing through PS Biomarker Services™.

It is difficult to be precise over the timing of when the full revenue contributions will be reflected but the scale and number of contracts in our order book is growing steadily and that performance is expected to continue in 2015.

Notes to the unaudited interim results

For the six months to 30th June, 2014

1. These interim financial statements have been prepared using policies based on International Financial Report Standards (IFRS and IFRIC Interpretations) issued by the International Accounting Standards Board ("IASB") as adopted for use in the EU. They do not include all disclosures that would otherwise be required in a complete set of financial statements and should be read in conjunction with the 31st December 2013 Annual Report. The financial information for the half years ended 30th June 2014 and 30th June 2013 does not constitute statutory accounts within the meaning of Section 434 (3) of the Companies Act 2006 and both periods are unaudited.

The annual financial statements of Proteome Sciences plc are prepared in accordance with IFRS as adopted by the European Union. The comparative financial information for the year ended 31st December 2013 included within this report does not constitute the full statutory Annual Report for that period. The statutory Annual Report and Financial Statements for 2013 have been filed with the Registrar of Companies. The independent Auditors' Report on that Annual Report and Financial Statement for 2013 was unqualified, did not draw attention to any matters by way of emphasis, and did not contain a statement under 498(2) or 498(3) of the Companies Act 2006.

After making enquiries, the directors have concluded that the Group has adequate resources to continue operational existence for the foreseeable future. Accordingly, they continue to adopt the going concern basis in preparing the half-yearly consolidated financial statements.

The same accounting policies, presentation and methods of computation are followed in these interim consolidated financial statements as were applied in the Group's latest annual audited financial statements. In addition, the IASB have issued a number of IFRS and IFRIC amendments or interpretations since the last Annual Report was published. It is not expected that any of these will have a material impact on the Group. The Board of Directors approved this interim report on 29th September 2014.

2. Loss per share from continuing operations

The calculation of the basic and diluted loss per share is based on the following data:
