Item 5. Other Events

      On July 17, 2003, Alteon Inc. issued the following press release:


              -- Additional Phase 2 Studies Being Planned Based on
                       Drug's Activity at Lower Doses --

Ramsey, New Jersey, July 17, 2003 - Alteon Inc. (AMEX: ALT) today announced
initial results from its multi-center Phase 2b SAPPHIRE and SILVER clinical
trials of the company's lead A.G.E. Crosslink Breaker, ALT-711, in the treatment
of patients with uncontrolled systolic hypertension. The five-arm SAPPHIRE trial
and the two-arm SILVER trial evaluated ALT-711's effectiveness in a total of 768
patients having elevated systolic blood pressure (systolic hypertension) without
or with enlargement of the left ventricle of the heart. The trials were
dose-ranging, double-blind, placebo-controlled and conducted at over 60 sites
nationwide. All patients were maintained on background hypertension medication.

ALT-711 did not demonstrate statistical significance as compared to placebo
against the pre-specified primary endpoint of reduction of systolic blood
pressure by office cuff pressure measurement at the highest of the four active
dose levels, 210 mg per day. The data analysis was confounded by a 6-10 mm Hg
drop in systolic blood pressures in all arms of the SAPPHIRE and SILVER trials,
including placebo, during the first two weeks after patient randomization.
However, patients in the SAPPHIRE "intent-to-treat" population demonstrated
efficacy net of placebo, in the 2-3 mm Hg range by cuff pressure, at the lower
end of the ALT-711 dosing range. In patients who completed their dosing regimen
in the SAPPHIRE study, this effect at lower doses was amplified and strengthened
to about 4 mm Hg net of placebo by ambulatory blood pressure measurements
(ABPM). ALT-711 was safe and well tolerated across all dosing groups. No
differences were noted between the SAPPHIRE and SILVER results.

"We believe that this is a meaningful signal of ALT-711's activity," said George
L. Bakris, M.D., Professor of Preventive Medicine and Internal Medicine and
Director of the Hypertension Clinical Research Center at Rush-Presbyterian St.
Luke's Medical Center in Chicago and lead investigator on the SAPPHIRE and
SILVER trials. "A 4 mm Hg reduction in systolic blood pressure on top of
existing hypertension medications, if confirmed in further studies, would be an
important addition to the treatment of this patient population."

"Based on discussions with our external advisors, we believe that the current
results are robust and consistent with earlier findings about the biological
activity of ALT-711," said Robert C. deGroof, Ph.D., Senior Vice President,
Scientific Affairs. "We now have further evidence of efficacy against systolic
hypertension in addition to existing evidence in diastolic heart failure (DHF),
medical conditions that are due to age-related stiffening and for which there
are clear, unmet needs."

"Following on what has been reported in previous preclinical and clinical
evaluation, the SAPPHIRE and SILVER data support continued development of
ALT-711 in systolic hypertension to confirm the appropriate dose," said Kenneth
I. Moch, President and CEO of Alteon. "This new information leads us to plan a
simple and relatively short confirmatory dose-ranging and mechanism of action
study, and we are already working with our advisors to refine our follow-on
clinical strategy. Assuming positive data from the next Phase 2 trial, we
anticipate that we would enter into Phase 3 pivotal trials in systolic
hypertension in 2005."

Earlier this year, Alteon announced that treatment with ALT-711 in DHF (the
DIAMOND study) demonstrated that patients who received 210 mg of ALT-711 twice a
day in an open-label, 16-week trial experienced a statistically significant
reduction in left ventricular mass, a marked improvement in left ventricular
diastolic filling and a positive effect on patients' quality of life.

Alteon will hold a conference call at 8:30 a.m. (ET) this morning. Participating
in the call along with Alteon senior management will be several external
advisors to the company. The call-in telephone number for the conference call
will be 1-800-838-4403. International participants may call 1-973-317-5319.
Participants should call approximately 5-10 minutes before 8:30 a.m. In
addition, the conference call will be accessible through a webcast on the
company's website, at the Investor Relations section, and a
digital rebroadcast will be available through July 24, 2003 by dialing
1-800-428-6051, passcode 301228 for domestic callers and 1-973-709-2089,
passcode 301228 for international callers.


The Phase 2b SAPPHIRE (Systolic And Pulse Pressure Hemodynamic Improvement by
Restoring Elasticity) and SILVER (Systolic Hypertension Interaction with Left
VEntricular Remodeling) trials evaluated ALT-711's effectiveness in 768 patients
having elevated systolic blood pressure (systolic hypertension) without or with
enlargement of the left ventricle of the heart (left ventricular hypertrophy or
LVH). The trials were dose-ranging, double-blind, placebo-controlled and
conducted at over 60 sites nationwide.

In the SAPPHIRE trial, patients were randomized into one of five treatment arms
(four different oral tablet doses of ALT-711 or placebo). In the SILVER trial,
patients were randomized to one of two treatment arms (ALT-711 or placebo).
Patients were dosed once a day for six months, in addition to their existing
medications. Patients enrolled in the trial are older than 50 years of age, had
a systolic blood pressure of greater than 150 mm Hg and diastolic blood pressure
of less than 90 mm Hg, and had thickening of the left ventricle of the heart as
measured by echocardiography. The trial included male and female, non-diabetic
and diabetic patients. The primary endpoints of the studies were the change in
systolic blood pressure. Secondary endpoints included additional blood pressure
measurements and changes in certain urological characteristics.

About Alteon

Alteon is developing several new classes of drugs that reverse or slow down
diseases of aging and complications of diabetes. These compounds have an impact
on a fundamental pathological process caused by protein-glucose complexes called
Advanced Glycation End-products (A.G.E.s). The formation and crosslinking of
A.G.E.s lead to a loss of flexibility and function in body tissues, organs and
vessels and have been shown to be a causative factor in many age-related
diseases and diabetic complications. Alteon has created a library of novel
classes of compounds targeting the A.G.E. Pathway. These include A.G.E.
Crosslink Breakers, A.G.E. Formation Inhibitors and Glucose Lowering Agents.
Alteon's lead compound ALT-711 is the only A.G.E. Crosslink Breaker in advanced
human testing. For more information on Alteon, visit the company's website at
