Comments by the CEO

During the first half of this year, we have initiated two phase II studies in cooperation with our partners. This marks the beginning of a new and pivotal period for BioInvent. Together with other on-going clinical studies, we hope to see these innovative projects generating substantial shareholder return over the next 18 months.

One purpose of the private placement in early June was to secure financing of the clinical programs and help us get beyond critical data points lying ahead of us. This private placement was launched in a difficult stock market environment but I am convinced that the improved financial position will over a longer term allow us to carry out our clinical program with even better prospects for shareholder return.

We also managed to broaden the international investor base with several well-regarded names. Our business is highly global including important alliances with a number of international pharmaceutical companies. In this respect, a larger international shareholder base and an improved international attention to our share is a prerequisite for consolidating and further improve our business.

Thrombosis (TB-402)

Project status

A phase IIb study of the prevention of venous thromboembolism (VTE) after total hip replacement surgery was initiated in April. The study is a multicentre, double blind, randomized controlled study evaluating safety and efficacy of two dose levels of TB-402, 25 and 50 mg unadjusted for patient weight, compared to the recently approved Factor Xa inhibitor rivaroxaban (Xarelto, Bayer/Johnson&Johnson).

The primary endpoint is made up of a composite of symptomatic VTE and asymptomatic deep-vein thrombosis (DVT) as detected by venography, all evaluated on day 35. VTE consist of both DVT and pulmonary embolism. The primary safety endpoint is the number of patients with a serious or clinically relevant non-serious bleed as from the inclusion in the study up to day 35. The trial will enrol 600 patients across approximately 40 centres in Europe. Results are expected in the second half of 2012.

Results from a previously completed phase II study on patients after total knee replacement were published in February 2011 in the Journal of Thrombosis and Haemostasis (JTH). The study showed that TB-402 was associated with a significantly lower rate of VTE compared with the low-molecular weight heparin enoxaparin (Lovenox, sanofi-aventis) with comparable safety data. Enoxaparin is the current standard therapy for prevention of VTE in this patient setting.

Background

TB-402 is a human antibody binding to Factor VIII. The antibody has shown a beneficial partial inhibition of Factor VIII. The objective is to initially develop a drug that prevents deep vein thrombosis and pulmonary embolism. Deep vein thrombosis caused when a blood clot forms in a deep vein, most commonly in the deep veins of the lower leg. Deep vein thrombosis is a major public health issue and it is estimated that in the US alone, more than 600,000 individuals are affected by deep vein thrombosis or pulmonary embolism each year. The number of patients undergoing total hip or knee replacement is estimated at around 2.4 million in 2009 and is expected to grow to approximately 3.1 million 2015 in the seven major pharmaceutical markets. Patients undergoing hip replacement or knee surgery are particularly at risk of developing deep vein thrombosis and all patients are therefore treated with anticoagulants prophylactically in order to reduce the risks of blood clots. TB-402 is a long-acting agent, which means it could be given as a single dose to prevent the development of deep vein thrombosis in patients undergoing surgery. This simple approach to prophylaxis would be an attractive option, as all current anticoagulant treatment options require daily treatment for up to several weeks. The project is carried out within the alliance with ThromboGenics.

Results from the phase I trial show that TB-402 is both safe and well-tolerated. No serious adverse events related to TB-402 were reported. The pharmacokinetic analysis undertaken as part of the phase I trial confirm a prolonged half-life of approximately three weeks. Additional studies have shown that the effect of TB-402 can be reversed by giving the target protein (Factor VIII) that blocks TB-402 and also that TB-402 is safe and well tolerated in individuals that are given standard treatment (enoxaparin and warfarin) for deep vein thrombosis.

Atherosclerosis (BI-204)

Project status

A phase II study was initiated in March with BioInvent’s antibody BI-204. BioInvent received USD 15 million in a milestone payment from Genentech at the start of the study. This product candidate is being developed for secondary prevention of cardiovascular events in patients with acute coronary syndrome.

In this randomized, placebo controlled, double blind, multicentre phase II study, BI-204 was delivered intravenously to patients on top of standard-of-care therapy for stable atherosclerotic coronary disease. The trial will enrol 120 patients at approximately 20 centres in the United States and Canada. It is designed to demonstrate a reduction in plaque inflammation following treatment as quantified by FDG-PET imaging (18F 2 deoxyglucose positron emission tomography). Plaque inflammation is an important risk factor for the development of atherosclerosis and coronary artery disease. It is expected that the study will be reported in the first half of 2012.

Background

The product candidate BI-204 targets oxidized forms of the LDL cholesterol. Links have been shown between oxidized forms of certain lipoproteins and the inflammatory processes that lead to plaque formation in the vessel walls. BI-204 has in preclinical studies reduced inflammatory processes and plaque formation significantly. The results also show a considerable reduction in the size of existing plaques in animals treated with BI-204. Results support that the mechanism behind BI-204 is a modulation of the inflammatory process resulting in a reduction of pro-inflammatory cells in treated plaques, which in turn leads to a reduction in new plaque formation and the regression of existing plaques. It is being developed as a drug for the prevention of secondary events in patients with cardiovascular disease. In a population-based, prospective, observational study of the risk of development of metabolic syndrome (JAMA. 2008; 299 (19) 2287-2293) higher concentration of oxidized LDL was associated with increased incidence of metabolic syndrome overall, as well as its components of insulin resistance and hyperglycemia. These observations support the picture that oxidized LDL can be an important target structure for developing new medications to treat patients with type 2 diabetes and metabolic syndrome. BI-204 is developed in collaboration with Genentech, a member of the Roche Group.

The phase I program was completed in 2009. The study was a double-blind, within-group randomised dose-escalation trial testing both single and multiple doses of BI-204 administered either intravenously or subcutaneously. In total, 80 healthy male or female subjects with elevated levels of LDL cholesterol were included in the trial. BI-204 was well tolerated and pharmacokinetic results showed the half-life was in the expected range for fully human antibodies.

Cancer (TB-403)

Project status

Development partner Roche initiated in May a phase Ib/II study in patients with glioblastoma multiforme, an aggressive type of primary brain tumour in humans. This trial will examine the safety and clinical effect of TB-403 (RG7334) in combination with Avastin® (bevacizumab) in patients with recurrent glioblastoma. Secondary objectives include safety, tolerability and pharmacokinetics of the combination. An evaluation of candidate biomarkers will also be included. The study will recruit approximately 100 patients. The start of the study triggered a €4 million milestone payment to BioInvent and ThromboGenics.

In March the first patient was dosed in a phase Ib study of TB-403 (RG7334) in combination with sorafenib in patients with primary liver cancer (hepatocellular carcinoma). The study will have a dose-determination part for safe TB-403 dosing in combination with sorafenib and a more explorative part where the safety, pharmacokinetics and pharmacodynamics of the combination will be studied. The study will include 60–70 patients.

Background

The product candidate TB-403 is a monoclonal antibody that blocks tumour angiogenesis, the development of new blood vessels, which is required for tumour nutrient and oxygen supply supporting tumour growth. By blocking angiogenesis, tumour progression and metastasis is prevented. TB-403 is directed against the placental growth factor, PlGF, secreted by tumours and specifically over expressed in cancer and chronic inflammatory conditions. It affects the formation of new vessels in tissue that is under stress. Normal vasculature is not dependent of PlGF. Mice lacking PlGF are healthy and reproduce normally. Hence blocking PlGF is expected to be a relatively safe and well tolerated anti-angiogenic treatment. TB-403 has been shown to inhibit tumour growth in animal models.

Up to June 2008 the project was carried out within the alliance with ThromboGenics. In June 2008 BioInvent and partner ThromboGenics entered into a strategic license agreement with Roche for development and commercialisation of TB-403. Roche received a worldwide, exclusive license to develop and commercialise TB-403. BioInvent and ThromboGenics retained co-promotion rights for the product in the Nordic, Baltic and Benelux regions.

The first phase I study in 16 healthy male subjects showed that TB-403 is safe and well tolerated. A follow-up study in patients with advanced cancer was presented in November 2009 at the AACR-NCIEORTC International Conference on Molecular Targets and Cancer Therapeutics in Boston, U.S. TB-403 was shown to be well tolerated and no dose limiting toxicity was observed with doses up to 10 mg/kg weekly and 30 mg/kg every three weeks. In this patient population with advanced solid tumours, stable disease was observed in six of 23 patients whereof two patients had stable disease in 12 months. A DCE-MRI imaging study of TB-403 was concluded in September 2010.

Cancer (BI-505)

Project status

A phase I study in patients with multiple myeloma is on-going. The study explores safety, pharmacokinetics and pharmacodynamics with the aim to define the optimal dose of the antibody for upcoming clinical phase II development. Patients are treated with intravenous doses of BI-505 every other week for a 28-day period with the possibility of extending the treatment until the condition deteriorates again. Recruitment of patients is done at three clinics - two in the U.S. (University of Utah Health Sciences Center and University of Maryland Greenbaum Cancer Center) and one in Sweden (Lund University Hospital). Dosing of patients in dose cohort nine, out of originally nine planned cohorts, is on-going. An important aim of the study is to increase dosing until maximum tolerated dose is reached. Based on how well tolerated BI-505 has been in earlier dose cohorts, the Company has applied for and gained acceptance from the US and Swedish drug authorities to expand the study with more cohorts at higher dose levels. In spite of this expansion, we still expect to report results from the study by the end of this year.

Background

The drug candidate BI-505 is a human antibody that targets the adhesion protein ICAM-1 (also called CD54). In tumour cells the expression of ICAM-1 is elevated and it is therefore a candidate for being a suitable target protein for a therapeutic antibody. In addition to inducing apoptosis the antibody also provides important immunoeffector functions that help to kill tumour cells. BI-505 has in different animal models proved to be very effective at killing tumours and more effective than existing drugs.

BioInvent’s intention is, in an initial stage, to treat patients with multiple myeloma. Other forms of hematologic cancer may also become relevant as indications. The possibility of treating ICAM-1 expressing solid tumours is also being explored. The number of newly diagnosed patients with multiple myeloma is more than 40,000 per year and the number of newly diagnosed patients with blood cancer is more than 200,000 per year.

BI-505 has been granted orphan drug designation in the United States and Europe for the indication of multiple myeloma. This status gives BI-505 possibility for market exclusivity for treatment of multiple myeloma with an antibody against ICAM-1 for up to 10 years after marketing approval is obtained.

Research projects

BioInvent is running a number of projects in the research phase i.e. the stage prior to selection of a Candidate Drug. The Company’s research portfolio currently includes projects mainly within the areas of cancer and inflammation. In the area of cancer, the research is focused on programmed cell death inducing antibodies with a strong ability to kill tumour cells, as well as activation of the body’s own immune defence cells. BioInvent is also working in cooperation with a leading academic team in the UK on the possibility of using new therapeutic antibodies to strengthen these mechanisms of action and the effect of already approved and clinically well-tolerated therapeutic antibodies.

With BioInvent’s F.I.R.S.T. platform, where antibodies are identified directly based on their powerful ability to kill primary cancer cells through differentially expressed, cancer cell-associated surface receptors, the Company is looking for new drug candidates for the treatment of various haematological cancers. The cooperation with leading Swedish and international academic teams was initiated with the objective to develop antibodies for the treatment of serious haematological and solid cancers through new pharmaceutical concepts based, for example, on the role of cancer-associated fibroblasts in tumour growth.

The Company’s inflammation research is being enhanced by a partnership entered into in March 2010 with the US company Human Genome Sciences. Under this partnership the companies will work together to develop and commercialise antibody-based drugs based on target proteins from Human Genome Sciences’ research and BioInvent’s antibody technology. The Company’s initiatives in oncology and inflammation have in common the development of therapies that impede the functions and activity of myeloid cells.

The Company is also conducting research and development on antibody-based drugs in cooperation with other external partners. Such partners include Bayer HealthCare, Daiichi Sankyo and Mitsubishi Tanabe. All in all BioInvent has entered into agreements of this kind with the possible development of up to 30 antibody-based products. As well as undisclosed license fees and research funding, BioInvent will receive milestone payments and royalties on sales of any products commercialized.
