Chairman's report

This has been an important quarter for the Company, during which the benefits of
our alliance with Roche have begun to flow through in both financial and
practical terms. Most importantly, however, we have continued to work hard to
advance our pipeline at all stages and to look at a number of opportunities for
in-licensing new products.

R1549 (formerly Pemtumomab)
We have announced today a refined prediction of the completion date for our
pivotal phase III trial (SMART) of R1549 in ovarian cancer. This is the latest
in a series of predictions made by the trial's independent Data Safety
Monitoring Committee (DSMC). The predictions are based on statistical modelling
using blinded data from the trial, and indicate when the trial is most likely to
finish and the range of possible completion dates. In November 2002, we were
informed that the peak likelihood for completion lay in July 2004, consistent
with our previously stated expectation of H2 2004. The DSMC's latest prediction
suggests a slightly earlier completion date, with the peak likelihood in April
2004 and 95% confidence that the date will fall between February and August
2004. The expected timing for the interim analysis has also been refined; this
is likely to take place during Q3 of this year (previous guidance was H2). These
refinements reflect the increasing accuracy of the predictions as the end of the
trial draws nearer. The new predictions for the study's completion fall within
the range of the November prediction and the previous one, suggesting that the
assumptions in the statistical models are still correct. At this stage there is
still some potential for changes in the expected completion date with further
predictions from the DSMC. Along with the current predictions, the DSMC has
reported that there are no safety data or other concerns that warrant changes in
the conduct of the study.

SMART (Study of Monoclonal Antibody Radioimmuno-Therapy) is one of four studies
underway on R1549. We are conducting two other ovarian cancer trials, MIDAS (Mab
Imaging and Dosimetry Assessment Study) and TOPDOC (Treatment of Peritoneal
Disease in Ovarian Cancer). MIDAS is a biodistribution study while TOPDOC will
provide additional data on the activity and tolerability of R1549. TOPDOC
includes a cohort of patients with 'minimal residual disease' following surgery
and chemotherapy. These patients still have some visible tumour remaining after
standard treatment, in contrast to the patients in previous studies who were in
complete remission (having no visible disease) after surgery and chemotherapy.
Both MIDAS and TOPDOC will contribute to the enlargement of the safety database
for R1549. The fourth study is a pilot phase II study in gastric cancer.
Preliminary results were reported during 2002 and final results will be
available following the completion of the study later this year.

AS1404 (DMXAA)
We have also announced today that screening of patients has started for our new
phase I study of AS1404 (DMXAA). This small study is being conducted in New
Zealand and will enrol around 12 patients with a variety of different solid
tumours. The aim of the study is to define appropriate doses for use in the
planned phase II programme.

AS1406 (formerly TheraNase)
Last week the first animal data were presented on AS1406 (formerly TheraNase),
which is the subject of a Collaborative Research and Development Agreement with
the US National Institutes of Health. The work was conducted in the laboratory
of Prof Susanna Rybak at the National Cancer Institute and showed encouraging
anti-tumour effects in both breast and lymphoma models.

Management developments
We recently announced the promotion of Dr Nigel Courtenay-Luck to Chief
Scientific Officer. Nigel continues to lead our preclinical operations but will
also now play a greater role in the assessment of new in-licensing opportunities
and the expansion of our network of collaborators. These areas are critical to
the successful operation of our business model.

Patent and licensing developments
We have recently been granted European patents for R1550 (huHMFG1; formerly
Therex) and for the caspase enzymes under investigation in our targeted
apoptosis programme.  Meanwhile, we have signed an agreement with Amersham 
to provide them with a non-exclusive license to develop RGD-containing peptides
under our relevant European and US patents. This is non-core technology that is
no longer under development at Antisoma.


Financial Review

Revenue Recognition
Following the formation of our alliance in November 2002, we received from Roche
non-refundable upfront payments totalling $37 million (#23.15 million) in return
for rights to our four clinical products and an option on new oncology compounds
entering trials over a five-year period. $35 million was received by 31 December
2002 and $2 million was received in the quarter ended 31 March 2003. These
upfront payments are allocated to the various products in accordance with the
terms of the contract and will be recognised as revenues over the estimated
period for completion of the relevant phase of clinical development for each
product.

Total revenues recognised from these upfront payments for the current quarter
are #2.3 million. It is expected that these quarterly revenues will continue at
the same level until 31 December 2004, falling thereafter.

In addition to the upfront payments, Roche will make payments equivalent to the
costs incurred by Antisoma in the continued development of R1549 and R1550.
These amounts are payable quarterly in arrears but will be recognised in the
same quarter as the expenditure to which they relate.

Results of operations - three months ended 31 March 2003
Revenue in the quarter increased to #4.2 million from #2.5 million in the
quarter ended 31 December 2002 and #0.4 million in the quarter ended 31 March
2002. #2.3 million of revenue arises from the recognition of a part of the $37m
upfront payments received from Roche and #1.9 million accrued in relation to the
development of R1549 (formerly Pemtumomab) and R1550 (formerly Therex) for the
quarter. Net operating expenses were #4.3 million, #4.4 million and #4.0 million
for the quarters ended 31 March 2003, 31 December 2002 and 31 March 2002. These
include research and development spending of #3.1 million, #3.4 million and #3.2
million, respectively, and administrative expenses of #1.2m, #1.0m and #0.8m,
respectively. Administrative expenses for the quarter have increased as a result
of costs associated with the completion of the Roche agreement. Total research
and development spending has remained steady as we continue to make progress on
each of the product candidates in the development pipeline. The increased
revenues flowing from the agreement with Roche together with maintained levels
of expenditure on research and development have resulted in operating losses
that are significantly lower at #93,000 from #1.9 million in the quarter ended
31 December 2002 and #3.6 million in the quarter ended 31 March 2002. Interest
income has increased as a result of higher cash balances to #350,000 from
#148,000 for the quarter ended 31 December 2002 and #26,000 for the quarter
ended 31 March 2002. Net profit for the period was #0.2 million (#0.65 million
loss for the quarter ended 31 December 2002; #3.6 million loss for the quarter
ended 31 March 2002). Research and development expenditure is expected to
increase as the clinical programmes for R1550, AS1404 (DMXAA) and AS1405
(formerly AngioMab) commence during this year.

Results of operations - nine months ended 31 March 2003
Revenues for the nine months ended 31 March 2003 totalled #7.1 million (9 months
ended 31 March 2002: #1.5 million), representing #1.3 million (2002: #1.5
million) of revenue recognised from the now terminated Development and Licence
Agreement with Abbott together with #5.8 million (#nil) from Roche. Operating
losses for the nine months ended 31 March 2003 fell to #5.2 million (2002: #9.9
million) and net losses fell to #3.4 million (2002: #9.7 million) as a result of
the increased revenues. Net operating expenses were #12.3 million (2002: #11.3
million) and included research and development expenses of #9.2 million (2002:
#8.7 million).

Liquidity and capital resources
Cash at bank and held in short-term investments totalled #34.9 million at 31
March 2003, #37.6 million at 31 December 2002, #18.9 million at 30 June 2002 and
#1.1 million at 31 March 2002. In the quarter ended 31 March 2003 Antisoma
received additional non-refundable upfront payments for the purchase of product
rights totalling $2 million, which were converted into #1.25 million at an
exchange rate of #1= $1.598.

Of the #23.1 million non-refundable upfront payments received, #3.0 million has
been recognised as revenue since inception of the agreement. The balance of
#20.1 million is shown as deferred revenue within creditors falling due within
one year and after more than one year and will be released to revenue as
described above in Revenue Recognition.

In the quarter Antisoma issued 20,733,240 ordinary 1p shares to Roche. The
payment for these shares of #4.15 million was received in the quarter ended 31
December 2002, and hence this amount was transferred during the quarter from
creditors to called-up share capital (#0.21 million) and the share premium
account (#3.94 million).

Net cash outflow from operating activities for the quarter was #7.1 million
(quarter ended 31 March 2002: #4.1 million outflow; quarter ended 31 December
2002: #20.9m inflow). Net cash outflow for the quarter reflects the increase in
debtors and reduction in creditors from 31 December 2002 to 31 March 2003 as
described below. The cash inflow from operating activities for the nine-month
period to 31 March 2003 was #10.3 million (2002: #7.8 million outflow).

Debtors have increased to #3.6 million (31 March 2002: #0.9 million; 31 December
2002: #1.6 million) due primarily to the accrual of amounts due from Roche
relating to the development of R1550 and R1549.

Creditors have increased to #22.9 million from #5.5 million as at 31 March 2002,
largely as a result of the non-refundable deferred revenue relating to the
upfront payments received from Roche. This is split between creditors falling
due within one year (#11.9 million) and creditors falling due after more than
one year (#11.0 million). Creditors have fallen from #28.0 million as at 31
December 2002 following the issue of ordinary shares and recognition as revenue
of part of the upfront payments received from Roche.

Loss per share
Earnings per share for the quarter are 0.1p compared to a loss per share of 3.7p
(restated to take account of the bonus element of the Rights Issue) for the
quarter ended 31 March 2002 and loss per share of 0.3p in the quarter ended 31
December 2002. Loss per share has decreased from 10.1p (restated to take account
of the bonus element of the Rights Issue) in the nine months ended 31 March 2002
to 1.6p in the nine months ended 31 March 2003.

Notes to the financial statements

1.      Basis of reporting
The quarterly financial statements have been prepared in accordance with UK
Generally Accepted Accounting Principles ("UK GAAP") on the basis of the
accounting policies set out in the Group's 2002 statutory accounts. The
statements were approved by the Board of Directors on 6 May 2003 and are
unaudited.

The financial information contained in this announcement does not constitute
statutory accounts within the meaning of Section 240 of the Companies Act 1985.
The figures for the year ended 30 June 2002 have been extracted from the
statutory accounts which have been filed with the Registrar of Companies and
which are available on request from the Company Secretary Antisoma plc, West
Africa House, Hanger Lane, Ealing, London W5 3QR. The auditors' report on those
accounts was unqualified and did not contain any statement under section 237(2)
or section 237(3) of the Companies Act 1985.

3.      Reconciliation to International Financial Reporting Standards
The Company's consolidated quarterly statement has been prepared under UK GAAP
which differs in certain respects from International Financial Reporting
Standards ("IFRS"). The principal differences between UK GAAP and IFRS that
affect the Group are set out below.

Preference Shares
The Company's preference shares may be settled using equity shares, with
the number of equity shares varying in such a way that the fair value of the
shares that would be issued would be equal to the obligation. These shares are
classified as non-equity shares under UK GAAP, but are classified as liabilities
under IFRS. The effect of this difference is that, under IFRS, shareholders'
equity is #4,332,000 lower than under UK GAAP in each financial period
presented, i.e. shareholders' equity under IFRS is #11,561,000 at 31 March 2003,
(#7,409,000) at 31 March 2002 and #10,809,000 at 30 June 2002. There is no
impact on the loss for any of the years presented.

Cash flow statement
Under UK GAAP, cash does not include short term deposits and investments which
cannot be withdrawn without notice and without incurring a penalty. Such items
are shown as short term investments. Under IFRS, deposits with a maturity of
three months or less at inception and which are readily convertible to a known
amount of cash, are included as cash and cash equivalents. Additionally, IFRS
requires only three categories of cash flow activity to be reported: operating,
investing and financing. The table below sets out the effect of differences
between UK GAAP and IFRS and provides the relevant disclosures required.
