The SRGN compound is DAB-IL-2 which is a diptheria conjugate with interleukin-2. The interleukin-2 binds to its receptor on the surface of the cell, and the toxin kills the cell. The drug will be before the FDA soon (the application for approval has been accepted for review for the treatment of CTCL, one of the indications for Targretin). The drug is also being tested on psoriasis, but LLY does not have rights to that indication.

The identification of the drug was actually quite simple. SRGN representatives were at one of the fall conferences (Robbie Stephens?), even though they had no presentations. They were also talking to LGND. The fusion protein was for psoriasis and CTCL, the same as Targretin, and LLY had the rights to CTCL. The market is relatively small, making it less interesting to LLY.

The compound could be approved in the next few months and could help LGND's bottom line in 1999 (and contribute toward that $0.84 profit and $131.5 million in income). However, there were some serious side effects associated with the drug and I suspect that some significant raining is required for administration. Therefore, a quick profit may not be as possible as originally assumed.

I suspect that treatment may be expensive, which could help justify a high prices for Targretin, and LGND could have three cancer treatments (oral and topical Targretin as well as DAB-IL-2), for a single disease, which is probably more than any one company anywhere.

Seragen Biologics License Application Accepted For Filing By FDA;
Application To Receive Priority Review

HOPKINTON, Mass., Feb. 4 /PRNewswire/ -- Seragen, Inc. (OTC Bulletin Board: SRGN - news) announced today the
U.S. Food and Drug Administration (FDA) has informed the company that its Biologics License Application (BLA) submitted
last December has been accepted for filing. The application requests clearance to market Seragen's DAB389IL-2
(Interleukin-2 Fusion Protein or denileukin diftitox) for the treatment of recurrent or persistent cutaneous T-cell lymphoma
(CTCL) in patients who have received prior therapy.

In addition, the FDA has designated the application for ''priority'' review. In the case of applications for drugs intended to treat
certain life- threatening illnesses, the FDA may choose to accelerate the review process. In this case, the FDA's designation
indicates the application may be reviewed in as little as six months.

CTCL is a form of non-Hodgkin's lymphoma that manifests initially in the skin. With time, however, the disease can become
systemic, involving the lymph nodes and the spleen, liver and other organs. CTCL is disfiguring and debilitating; median survival
for late-stage patients with organ or lymph node involvement is less than three years. Various drugs are used in treating the
disease, but no drug is specifically approved by the FDA for its treatment.

Seragen's BLA is based on accumulated data from Phase I/II and Phase III clinical trials of DAB389IL-2 in patients with
CTCL who were no longer benefiting from other therapy. Two additional trials are currently in progress to evaluate the use of
the drug in patients with CTCL who have been less extensively pre-treated. Results of the completed Phase III trial were
presented at the annual meeting of the American Society of Hematology in December.

Seragen is a biopharmaceutical company developing a proprietary portfolio of therapeutic products. The company's unique
receptor-active fusion proteins consist of a toxin fragment genetically fused to a hormone, or growth factor, that targets specific
receptors on the surface of disease-causing cells.

Seragen's current focus is on cancer and dermatology. In addition to a collaboration with Eli Lilly and Company [NYSE:LLY -
news] on the development of DAB389IL-2 (denileukin diftitox) for CTCL, Seragen is independently conducting investigational
clinical trials of the same molecule for psoriasis. A second product, EGF Fusion Protein, is currently in a Phase I/II
investigational clinical trial for non-small cell lung cancer and is the subject of an agreement with United States Surgical
Corporation [NYSE:USS - news] for collaborative development for restenosis following angioplasty.

Here's the psoriasis data:
Patients Using Seragen's Psoriasis Drug; Company Initiates Additional Trial

WASHINGTON, Nov. 13 /PRNewswire/ -- Speaking at an International Business
Communications conference on psoriasis in Washington, D.C. today,
dermatologist Jerry Bagel, M.D., disclosed that patients receiving a four-week
course of Seragen, Inc.'s (Nasdaq: SRGN) DAB389IL-2 receptor-active protein in
a Phase II clinical trial showed statistically significant improvement
compared to patients who received a placebo. Overall, 12 of 27 patients (44
percent) who received at least one dose of DAB389IL-2 exhibited at least 50
percent improvement from mean baseline disease severity scores. Only three of
12 patients (25 percent) treated with placebo showed similar improvement.
Dr. Bagel further noted that, in general, patients who received DAB389IL-2
and had improved psoriasis severity scores also had improved "quality of life"
scores and reduction of lesion thickness. On the other hand, placebo patients
did not show significant improvement in these measures of benefit.
"Patient improvement, as measured by change in the standard psoriasis
severity index, was comparable in two separate studies of the drug," Dr.
Bagel, director of the Psoriasis Treatment Center of Central New Jersey in
East Windsor, stated.
Dr. Bagel presented a summary of the findings from two studies involving
patients with moderate-to-severe psoriasis: Seragen's original open-label
Phase I/II psoriasis study consisting of five consecutive treatment days per
month; and a double-blind placebo-controlled Phase II study consisting of
three treatment days per week for four weeks.
The Phase II study tested doses of 5, 10 and 15 micrograms per kilogram
per day. Comparable improvement was observed at all three dose levels;
however, adverse events were more notable at the higher doses. Consequently,
Seragen has now initiated a dose escalation study to evaluate the potential
for anti-psoriatic effects starting at lower doses of DAB389IL-2. The new
study is being conducted at four medical centers in the U.S. Up to 45
patients will be enrolled and allocated to one of three dose groups.
"We are refining the dosing regimen for DAB389IL-2 in psoriasis," said
Seragen's president, Jean Nichols, Ph.D. "Our evidence indicates the drug is
active against psoriasis. We are now evaluating even lower doses as well as a
new schedule designed to improve the tolerability of the drug. While the
trial is taking place, we will design further psoriasis trials, some of which
may run concurrently with this trial."
Reed Prior, newly named Seragen CEO, added: "Psoriasis is a major
potential market. A recent survey reported by the National Psoriasis
Foundation estimated that 2.6 percent of the U.S. population suffers from
psoriasis. That translates into 6.4 million people. Twenty-four percent of
the patients surveyed said they had moderate psoriasis, and 9 percent, or over
half a million people, said they had severe psoriasis."
Seragen's current focus is on cancer and dermatology. In addition to the
psoriasis trial which the company is conducting independently, Seragen is
conducting PhaseIII clinical trials of DAB389IL-2 for cutaneous T-cell
lymphoma in collaboration with Eli Lilly and Company. The second product in
the company's pipeline, DAB389EGF, is currently in a clinical trial for non-
small cell lung cancer.
Seragen is an integrated biopharmaceutical company developing a
proprietary portfolio of therapeutic products. The company's unique receptor-
active proteins consist of a toxin fragment genetically fused to a hormone, or
growth factor, that targets specific receptors on the surface of disease-
causing cells.
