Further information is contained in this announcement. Interim report for the six months ended 30 June 2007 Copenhagen, Denmark - 15 August 2007 - The Board of Directors of TopoTarget A/S (OMX Nordic Exchange Copenhagen: TOPO) today adopted the company's interim report for the six months ended 30 June 2007. During the six months period ended 30 June 2007, operating expenses amounted to DKK 119.5 million against DKK 100.8 million in the year-earlier period, primarily due to the establishment of Savene™ sales forces in Europe and the USA. The operating loss for the period was DKK 93.7 million, compared with DKK 86.6 million in the same period of last year. The company posted a loss before tax of DKK 91.2 million in the first six months of 2007 against a pre-tax loss of DKK 84.4 million in the same period of 2006. Cash, cash equivalents and marketable securities amounted to DKK 519.9 million at 30 June 2007. Highlights for the first six months of 2007 • In June TopoTarget and CuraGen presented positive updated results on belinostat at the annual meeting in ASCO and at the 2007 Pan Pacific Lym-phoma conference. Most importantly we were able to announce proof-of-concept for belinostat given as single agent to patients with peripheral T-cell lymphoma. Belinostat also works alone in cutaneous T-cell lymphoma. In December 2006 we obtained proof-of-concept data in this disease and posi-tive update on these data were presented at the 2007 Pan Pacific Lym-phoma conference • On 24 May TopoTarget received an approvable letter from the FDA for Totect™ • On 27 June the acquisition of the Swiss biotech company Apoxis S.A. was completed. The TopoTarget clinical pipeline has accordingly been expanded with two promising anti-cancer compounds respectively in phase I and II trials • On 21 June TopoTarget completed a public offering that brought the com-pany a gross proceeds of DKK 360 million Expected key milestones for the remainder of 2007 • Approval of Totect™ and subsequent launch in the USA • Launch of Savene™ in additional European countries • Decision regarding regulatory strategy for belinostat • TopoTarget /CuraGen and the NCI have 15 ongoing studies with belinostat. Additional results are expected from the oral phase I trial and from three of the phase II trials • Results from Baceca® Phase II trial • Results from a Savicol™ Phase II trial Savene™/Totect™ status TopoTarget's first product, Savene™, is for the prevention of severe tissue damage caused by anthracycline extravasation. Savene™ was launched in Oc-tober 2006. Launch and commercial activities of Savene™ in Europe are moving forward according to plan. In Q2 2007 the Savene™ revenue amounted to DKK 4.6 million compared to DKK 3.7 million in Q1 2007. This is, as expected, an increase of 24 %. Sales of Savene™ amounted thus to DKK 8.3 million for the first six months of 2007. The figure below illustrates the quarterly Savene™ sales development, meas-ured in TDKK since its launch in October 2006. In the attached pdf page 3 is a figure showing the quarterly development in sales for Savene since launch in October 2006. Due to a technical issue at one of our two alternative manufacturing subcontrac-tors, TopoTarget received in May 2007 an approvable letter for Totect™ (the US brand for Savene™) from the FDA. TopoTarget expects a FDA approval soon and to launch Totect™ in the US market in the second half of 2007. Medical provider groups in the USA have expressed a high degree of desire to include Totect™ in the treatment protocols for anthracycline extravasation and TopoTarget has received a large number of requests regarding availability and education in the use of Totect™. Status of clinical activities TopoTarget's clinical pipeline consists of eight product candidates covering a broad range of cancer and other indications. The guidance on the development programs is consistent with previously an-nounced guidance unless otherwise specified below. Belinostat (PXD101) - an IV and oral pan HDACi for the treatment of multiple cancer indications Intravenously and orally administered belinostat is currently evaluated in 15 studies run by CuraGen, TopoTarget and the NCI (National Cancer Institute, US). Updated results regarding intravenously administered belinostat were presented at ASCO and the Pan Pacific Lymphoma Conference in June 2007 and the posi-tive response data further underlined the previously reported proof-of-concept data demonstrating belinostat to have anti-cancer effect in cutaneous T-cell lymphoma. In addition, the development of belinostat has been further strengthened with proof-of-concept data on yet another indication: peripheral T-cell lymphoma. Furthermore positive safety data was presented: Extensive ECG monitoring did not demonstrate a risk to heart function (No grade 3 QTc prolon-gation). • Thus, in the phase II study evaluating belinostat in cutaneous and pe-ripheral T-cell lymphoma, four of 14 patients (29%) with advanced cu-taneous T-cell lymphoma achieved objective response (1 CR (Complete Response) and 3 PR's (Partial Response)). Seventy-seven (77) % of the patients had skin lesion improvements. Five out of six patients with sig-nificant pruritus (itching) had a clinically meaningful reduction in pruri-tus • Among 11 evaluable patients with peripheral T-cell non-Hodgkin's lym-phomas one patient achieved a CR and one a PR. For both study groups enrolment has been expanded to enrol total of 34 patients each • Results from 23 patients with advanced solid tumors indicated that the combination of intravenous belinostat plus carboplatin and paclitaxel is well tolerated and confers efficacy in heavily pre-treated patients, in-cluding RECIST defined responses in pancreatic and rectal cancer, CA-125 response in ovarian cancer, and multiple long stabilizations of dis-ease (e.g. treatment duration of ≥ 1 year in bladder cancer, carcinoma of unknown primary, and melanoma). A Phase II portion of the trial for ovarian cancer has been initiated with 16 patients treated (13 patients still ongoing). Two of the ongoing patients had at the investigator meet-ing in June achieved an objective response resulting in the trial being expanded to enroll up to 32 patients. A second arm was added to this study and is currently enrolling up to 15 patients with transitional cell cancer of the bladder • On 7 August 2007 TopoTarget announced that a Phase I/II clinical trial evaluating belinostat in combination with idarubicin for the treatment of AML is being initiated at multiple sites in the EU • As announced 7 August 2007 the enrollment of further patients, in a Phase II open-label clinical trial evaluating intravenous belinostat in combination with Velcade® (bortezomib) for injection in patients with advanced refractory Multiple Myeloma, has been stopped until we have more knowledge of how to prevent certain complications in this specific patient population. Our resources on the development of belinostat will be concentrated on the other ongoing studies in cancer indications where belinostat has demonstrated a therapeutic benefit • Phase Ib results from 25 patients with advanced solid tumors treated with intravenously administered belinostat in combination with 96-h in-fusion 5-fluorouracil (5-FU) indicated that the combination is generally well tolerated, including positive safety data from extensive ECG moni-toring in all patients without any indications for Grade 3 QTc prolonga-tion). A total of seven patients achieved stabilization of disease (range 2 - 8 cycles); no RECIST defined responses noted. Enrollment of six addi-tional patients is being conducted to determine whether there is any ef-fect on the expression of Thymidylate Synthase (TS) in tissue samples Baceca® - an HDACi for the treatment of Basal Cell Carcinoma (BCC) TopoTarget currently conducts two randomised and blinded Phase II proof-of-concept trials to investigate Baceca® alone, and in combination with two differ-ent vitamin A like compounds for the treatment of BCC. These trials will enrol a total of approx. 100 patients. Savicol™ - an HDACi for the treatment of Familial Adenomatous Poly-posis (FAP) TopoTarget is currently conducting a Phase II pivotal trial, evaluating the effect of Savicol™ in the treatment of FAP. This randomised, placebo-controlled Phase II study takes place in Europe and is expected to enrol a total of 60 FAP pa-tients. APO866 - an NAD+ inhibitor for the treatment of cancer APO866 is a specific inhibitor of the key enzyme involved in the synthesis of NAD+. A phase I study has been completed, and 3 phase II studies are ongoing in the following indications: advanced melanoma, cutaneous T-cell lymphoma (CTCL) and B-cell lymphatic leukaemia (B-CLL). Zemab® - an antibody-toxin for the treatment of HER2 positive cancers (i.e. Head & Neck and breast cancer) One Phase I trial has been completed. Following a new production of Zemab®, new clinical studies are expected to be initiated in 2008. APO010 - a human Fas ligand protein for the treatment of cancer APO010 is a recombinant fusion protein targeting the Fas receptors on the sur-face of cancer cells. A phase I dose-finding study in patients with solid tumours is ongoing. Topotect - a Topoisomerase II inhibitor - a protectant to enable che-motherapy treatment of brain metastasis Phase I/II trials with different designs and treatment schedules are ongoing, exploring the potential of the combination of Topotect and etoposide. As recruitment of patients has been slower than earlier anticipated the first results are now expected to be announced in 2008. Avugane™ - an HDACi for the treatment of Acne Vulgaris Based on Phase II proof-of-concept results showing comparable efficacy and advantageous tolerability compared with a standard, marketed retinoid therapy, TopoTarget now conducts a double-blind, randomised, placebo control Phase II four-arm clinical trial in mild to moderate acne vulgaris.

See page 6 in attached pdf for "highlights and key figures" TopoTarget A/S The financial ratios have been calculated in accordance with “Recommendations & Ratios 2005”, issued by the Danish Society of Financial Analysts. The interim financial statements are unaudited. More detailed accounting information is provided in the appendices. Comments on the interim financial statements for the six months ended 30 June 2007 The company generated revenue of DKK 25.8 million during the period 1 January to 30 June 2007 compared with DKK 14.2 million in the same period of last year. Included in revenues are invoicing to CuraGen and Savene™ sales. The higher revenue in 2007 is mainly due to sales of Savene™ on various Euro-pean markets. In H1 2007, production costs amounted to DKK 13.0 million as compared with DKK 8.2 million in the same period of 2006. The higher costs were mainly due to increasing Savene™ sales in Europe. In H1 2007, research and development costs amounted to DKK 55.4 million as compared with DKK 62.1 million in the year-earlier period. The company now has in-house research activities which were outsourced in H1 2006. This has resulted in savings that allowed the company to perform more research work at the same cost. Sales and distribution costs were DKK 26.3 million in H1 2007, up from DKK 8.6 million in the year-earlier period. The increased costs were due to a higher number of sales representatives in Europe as Savene™ is being launched in more countries and also due to the sales force which is being established in the US for the launch of Totect™ in H2 2007. Marketing activities have been initi-ated in the US. In H1 2007, administrative expenses amounted to DKK 24.9 million as com-pared with DKK 22.0 million in the same period of 2006. Net financial income amounted to DKK 2.5 million in H1 2007, as compared with DKK 2.2 million in the year-earlier period. The increase is mainly due to higher interest income on securities. In H1 2007, tax amounted to DKK nil as compared with DKK 1.5 million in the same period of 2006. The tax income in H1 2006 was due to a reduction of de-ferred tax liability relating to the subsidiary TopoTarget Germany AG. Accordingly, the company recorded a loss after tax of DKK 91.2 million in H1 2007 as compared with a loss after tax of DKK 82.9 million in the year-earlier period. At 30 June 2007, total assets amounted to DKK 891.5 million. Of this amount, cash bank deposits and short-term securities amounted to DKK 519.9 million. At 30 June 2007, equity amounted to DKK 736.6 million compared with DKK 344.0 million at the same time in 2006. The change consists of a loss of DKK 183.0 million during the period from 1 July 2006 to 30 June 2007, the DKK 121.7 million capital increase in November 2006, additions during the period of share-based payment totalling DKK 5.4 million, the exercise of warrants total-ling DKK 7.4 million and fair value adjustment of the bond portfolio totalling DKK 1.1 million. Also included are net proceeds from the capital increase in connection with the acquisition of Apoxis S.A. in the amount of DKK 332.0 mil-lion and a non-cash contribution of DKK 107.9 million from the issuance of con-sideration shares to the former shareholders of Apoxis. Outlook for 2007 On 27 June 2007, the company completed the acquisition of Apoxis. After the acquisition of Apoxis, which increased the Group's combined costs for activities such as clinical trials, the company expects to report a pre-tax loss in the range of DKK 275 million to DKK 295 million for 2007. This is a reduction compared to the expected loss for 2007 disclosed in the pro-spectus dated 4 June 2007. The reason for the reduced expected loss is that TopoTarget in a period since the publication of the prospectus in coorporation with the newly acquired Swiss company has assessed that it is possible to ob-tain further positive synergy effects merging the research development and administrative activities etc. The company's cash burn may be higher than the expected pre-tax loss due to an increase in sales activities and the resulting change in working capital.
