Genzyme deal to evaluate MAb with thorium-payload
Price
52 week
Algeta and Genzyme (now owned by Sanofi-Aventis) have signed research
collaboration to allow the evaluation of a thorium-227 linked version of the
undisclosed Genzyme MAb. We presume this product candidate would be evaluated
in preclinical models, which, if successful, would provide the basis for the two
companies to negotiate a full development collaboration.
Breast cancer study data for Alpharadin soon
Meanwhile Algeta will shortly announce the results from its Phase II study of
Alpharadin (radium-223) in breast cancer, which may pave the way for partner Bayer
to initiate a Phase III study in this indication. Preclinical studies presented at AACR
suggest that Alpharadin may be effective in treating bone metastases characterised
by osteoclastic activity (as in breast cancer), which bodes well for any such studies.

Update: First thorium deal links Genzyme antibody
Algeta has entered into a research collaboration with Genzyme (now owned by Sanofi-Aventis) to
evaluate a thorium-linked version of an undisclosed tumour-targeting monoclonal antibody (MAb).
The collaboration, which has a term of up to one year, will allow the creation and initial evaluation of
a thorium-227 linked version of the Genzyme MAb generated using Algeta’s technology. If the
initial study is successful, Algeta and Sanofi-Aventis can be expected to seek to negotiate a full
collaboration for further development of the product.
This agreement is an important first step in Algeta’s strategic plan to establish a second platform
based on thorium-linked drug conjugates. Algeta is actively seeking to in-license antibodies onto
which it can conjugate Thorium-227 and collaborate with companies that already have such
products in development. Hence, it expects to sign a number of other similar evaluation deals for
antibodies, whose cell killing anticancer effect could be enhanced by the delivery of alpha radiation.
The companies have not disclosed the antibody or its specific target, although it would be
reasonable to assume it targets a cell surface antigen that is highly abundant on a tumour. A
scientific paper by Teicher, interestingly of Genzyme, reviews this field and lists a large number of
such potential tumour antigens (Current Cancer Drug Targets, 2009, Vol. 9, No. 8).
227
Algeta has already published preclinical studies with Th
-linked linked versions of trastuzumab

2
(Herceptin, Roche) and rituximab (Rituxan, Roche). However, these molecules were created to
demonstrate proof-of-concept but for a variety of commercial/competitive reasons they are not
3
expected to be developed further. Algeta is currently evaluating the Lumi4 chelator technology,
under an option from the US biotech company Lumiphore, and this will presumably be used to link
the thorium to the antibody. The Lumi4 technology binds lanthanides and actinides (thorium is an
actinide) by forming a cage structure that can be covalently attached to a range of tumour-targeting
molecules.
Algeta is well positioned to exploit the growing industry interest in antibody-drug conjugates as the
second wave of antibody-based cancer therapeutics. These are products that carry either a toxin
or a radionuclide to deliver radiation to achieve or potentiate the desired anti-tumour cell killing
effect of the antibody. There are around a dozen different toxin-linked antibody drug conjugate
products in active clinical development and a smaller number of radionuclide-linked products,
although most are in small academic studies. Two beta-emitting radionuclide-linked antibodies are,
however, approved for therapeutic use (Zevalin and Bexxar).
The short range of alpha particles (2-10 cell diameters) means that damage to healthy cells (and
hence side-effects) is sufficiently less than with beta radiation. Hence it seems likely that the debate
in the industry will be between the merits of alpha radionuclide versus toxin-linked antibodies.
Algeta believes that alpha-emitters have a number of specific advantages including the fact that
they do not need to be internalised into the cell and their localised bystander effect (whereby

This would realistically need an agreement with Roche, which is developing its own toxin-linked version of
Herceptin (T-DM1 or trastuzumab emtansine) in collaboration with ImmunoGen.

Algeta effectively achieved an exclusive commercial position in alpha-emitters, with its access to
thorium-227 source, a chelating technology and IP/know-how in this area. Selected radionuclidelinked antibodies are shown in Exhibit 1.

The development of a second platform based on thorium-linked drug conjugates is an important
strategic goal for Algeta, as it looks to develop a pipeline of products to follow Alpharadin. Algeta’s
investment case is effectively entirely centred on the successful development and commercial
exploitation of Alpharadin, which is in Phase III studies for the treatment of bone metastases arising
from prostate cancer. Alpharadin, which is subject to a global commercial partnership with Bayer,
is in a pivotal Phase III study, termed ALSYMPCA, which has completed recruitment and will shortly
undergo an interim analysis that may, in exceptional circumstances, allow an early registration filing.
However, there is a high statistical hurdle and the study should be presumed to run to completion.
Details on the three ongoing studies with Alpharadin are shown in Exhibit 2.

Breast cancer study data soon
Meanwhile Algeta should shortly announce the results from its Phase II study of Alpharadin (radium223) in breast cancer, designed to pave the way for the initiation of a second Phase III study. This
study is measuring biomarker data but should nonetheless provide some evidence of clinical
activity in an indication where the bone metastases are characterised by predominant osteolytic
activity (dissolution of bone). Bone metastases arising from prostate cancer are, by contrast,
characterised by predominant osteoclastic activity (formation of new bone).
Results of preclinical studies (conducted by Bayer) in a breast cancer model were recently
presented at the American Association for Cancer Research. The authors, Suominen et al, reported
that Alpharadin inhibited the differentiation of osteoclasts and progression of established, osteolytic
breast cancer bone metastases in the in vivo model.
Market positioning in mCRPC
Patients with prostate cancer are usually diagnosed when the cancer is at the hormone responsive
stage, but after a period of time on anti-androgens these patients will progress to CRPC (where the
diagnosis is made on the basis of a rapidly rising PSA level). These patients are usually
asymptomatic or only mildly symptomatic and standard therapy is docetaxel. However, as the
disease progresses, they tend to develop painful bone metastases (which are seen in >90% of
patients). Bone metastases can give rise to a variety of problems (including pain, fractures and
spinal cord compression), collectively termed skeletal-related events (SREs).
Currently zoledronic acid (Zometa, Novartis) is the standard treatment for delaying the onset of
SREs in multiple tumour types (including breast, lung and prostate), although this is changing with
the recent introduction of Xgeva (denosumab, Amgen/GlaxoSmithKline). Xgeva is indicated for
prevention of skeletal-related events (SREs) associated with bone metastases and the label may be
widened to include delaying the occurrence of bone metastases, following a positive Phase III trial.
Alpharadin specifically targets the bone metastases, it seems likely that it will be introduced for use
after the failure of (or in combination with) docetaxel or other agents. Xgeva is likely to provide the
benchmark against which Alpharadin will be compared, although the two agents may be used in
combination. The drug has been studied in four Phase III studies, of which two were in mCRPC,
which demonstrated a significant improvement in terms of delaying the onset of SREs over
zoledronic acid and placebo, but no improvement in overall survival. Hence if the ALSYMPCA study
demonstrates an increase in overall survival, as expected, it should become a significant
competitive advantage. There appear to be few potentially competing direct anti-bone metastatic
drugs in development (see Exhibit 3).

Sensitivities
Algeta is exposed to typical biotech company drug development risks, including the unpredictable
outcome of clinical trials, combined with a high single product risk (with substantially all of its value
residing in Alpharadin). In addition, the relationship with Bayer is important and, as with any
commercial relationship, there is a risk that a clinical trial setback or change in its partner’s R&D
priorities (eg prompted by M&A activity) could affect the relationship. Algeta’s functional currency is
the Norwegian krone, but a majority of its payments (and receipts) are made in euros. Algeta has
partially hedged its euro exposure, which, under IFRS, may give rise to non-cash items in its
accounts as they are marked to market at balance sheet dates. Algeta remains relatively tightly held
with two significant VC shareholders, Abingworth and Healthcap, each with 17% shareholdings.
Valuation
Our risk-adjusted NPV yields a valuation of $1.1bn (NOK6.4bn), which compares with Algeta’s EV
of NOK4.9bn. The valuation is based entirely on Alpharadin and uses conservative assessments of
the probability of success, market penetration, pricing and the economics of the Bayer partnership
(comprising development, regulatory and sales milestones, cost of goods margin and profit share
on co-promotion in the US). The valuation uses industry-standard risk adjustments based on the
stage of development in each indication and would therefore rise rapidly as higher probabilities can
be safely assumed (eg on a Phase III start in breast cancer). We note that currently the market
capitalisation accounts for a relatively high proportion (c 82%) of the rNPV by comparison with
biotech industry norms, which may limit the upside potential in the short term.
Financials
Algeta’s year-end cash was NOK479m. We have modelled an R&D expenditure of NOK175m this
year (and a hypothetical NOK250m in FY12) with NOK150m reimbursed in both years by Bayer.
Algeta can earn some $160m of milestones from Bayer from development and regulatory events
(the majority are related to filing and first sales in prostate cancer), with some $580m of milestones
payable on achievement of sales targets. A summary of the terms of Algeta’s global
commercialisation deal with Bayer are summarised in Exhibit 4.

Copromotion
Up some $160m on development and regulatory events (the majority are related to filing and
first sales in prostate cancer).
Some $580m is payable on achievement of sales targets, believed to be mostly a significant
sum on achievement of blockbuster sales (eg >$1bn/year).
Tiered double-digit, understood to be rise to >20% of sales.
Bayer funds just over 70% of the costs for ongoing prostate and breast cancer studies and
will fund in full any additional late-stage trials that may be required to gain approval.
Algeta has an option to co-promote in the US (with up to 50% participation). It intends to
exercise this participation right in full, which will require a significant investment in the
establishment of commercial infrastructure.
Supply
Algeta is responsible for global commercial supply. It is establishing a manufacturing facility
at the Institute for Energy Technology (IFE), in Kjeller, Norway, for commercial production.
Source: Edison Investment Research
On this basis, we believe Algeta is funded comfortably well beyond 2013, when it expects to have
Alpharadin approved and launched. No milestones are reflected in the financial model until
received, as per our policy. Our financial model is shown in Exhibit 5.
