This Amendment No. 7 amends and restates the Schedule 13D relating to the
holdings of Baxter Healthcare Corporation, a Delaware corporation ("Purchaser"),
of 3,500,000 shares (the "Shares") of common stock, $0.001 par value per share
("Common Stock"), of Nexell Therapeutics Inc. (formerly known as VIMRx
Pharmaceuticals Inc.) (the "Company"); a Warrant to purchase 1,300,000 shares of
Common Stock; and 83,705 shares of Series A Preferred Stock presently
convertible into 7,609,546 shares of Common Stock.

ITEM 1.       SECURITY AND ISSUER.
This statement relates to the Common Stock of the Company. The address of the
principal executive offices of the Company is:

                                    9 Parker
                          Irvine, California 92618-1605

ITEM 2.       IDENTITY AND BACKGROUND.
This statement is being filed by Purchaser and Baxter International Inc., a
Delaware corporation and the owner of 100% of the capital stock of Purchaser
(the "Parent"). The principal executive offices of Purchaser and Parent are:

                               One Baxter Parkway
                            Deerfield, Illinois 60015
                             Telephone: 847.948.2000

Purchaser and Parent, through its subsidiaries, are engaged in the worldwide
development, distribution and manufacture of a diversified line of products,
systems and services used primarily in the health care field.

Neither Parent nor Purchaser, nor, to the best of the knowledge of Parent and
Purchaser, any director or executive officer of Parent or Purchaser, has been,
during the last five years, (a) convicted in a criminal proceeding (excluding
traffic violations or similar misdemeanors) or (b) a party to a civil proceeding
of a judicial or administrative body of competent jurisdiction and as a result
of such proceeding was or is subject to a judgment, decree or final order
enjoining future violations of, or prohibiting or mandating activities subject
to, federal or state securities laws or finding any violation with respect to
such laws.

ITEM 3.       SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION
As described in Item 4 below, in consideration of the Purchaser's tender of
common stock, warrants and debentures of Issuer's subsidiary to the Issuer,
Purchaser received from Issuer 750,000 shares of Common Stock, a warrant to
purchase 1,300,000 shares of Common Stock, and certain debentures of the Issuer.

--------------------------------------------------------------------------------

ITEM 4.    PURPOSE OF TRANSACTION.
Prior to June 30, 1999, the Company owned 80.5% of Nexell of California, Inc.
(formerly known as Nexell Therapeutics Inc.) ("Sub"), the Company's principal
business unit, which it acquired through the acquisition of certain assets from
Purchaser in December 1997 in exchange for (1) 2,500,000 shares of Common Stock,
(2) 66,304 shares of Series A Convertible Preferred Stock of the Company with a
liquidation value of $1,000 per share ("Series A Preferred Stock"), (3) 19.5 %
of Sub's outstanding common stock, (4) a warrant to purchase an additional 6% of
Sub's common stock for $6,000,000, and (5) the right of Purchaser to receive
payments from Sub upon the occurrence of certain milestone events, which could
aggregate $21,000,000 if all the milestones were achieved. In addition, for
$30,000,000 paid to Sub, Purchaser received $30,000,000 principal amount of
Sub's 6 1/2% convertible subordinated debentures convertible into Sub's common
stock upon a public offering of common stock by Sub.

The acquisition by the Company of Purchaser's interests in Sub, other than its
right to milestone payments, was effected through an exchange of Purchaser's
interests in Sub for an equivalent value of interests directly in the Company
(the "Acquisition"). The Company and Purchaser agreed to exchange Purchaser's
interests in Sub (common stock, warrant and convertible subordinated debentures,
but excluding its right to milestone payments ) for:

..    750,000 shares of Common Stock;

..    an adjustment of the conversion price of the shares of Series A Preferred
     Stock owned by Purchaser to $11.00 per share;

..    a warrant to purchase 1,300,000 shares of Common Stock at a price of $4.60
     per share (the "Warrant"); and

..    $32,884,537.50 principal amount of 6 1/2% Convertible Subordinated
     Debentures convertible, commencing November 30, 2002, into Common Stock at
     a conversion price equal to 95% of the average of the closing prices of the
     Common Stock on the Nasdaq National Market for the 30 consecutive trading
     days preceding the date of conversion.

On May 28, 1999, December 17, 1999, December 17, 2000 and December 17, 2001,
pursuant to the terms of the Series A Preferred Stock owned by Purchaser, the
Company, respectively, issued 3,978, 4,216, 4,469 and 4,738 additional shares of
Series A Preferred Stock to Purchaser as a result of dividends payable in kind.

Other than as described herein in Items 4 and 6, neither Purchaser nor Parent
presently has any plans or proposals which relate to, or may result in, any of
the matters listed in Items 4(a) - 4(j) of Schedule 13D, although each reserves
the right to develop such plans.

--------------------------------------------------------------------------------


ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER.
Except as set forth herein, neither Purchaser, Parent, nor, to the best of the
knowledge of Purchaser and Parent, any director or executive officer of
Purchaser or Parent beneficially owns any other shares of Common Stock of the
Company.

         (a)    Purchaser and Parent beneficially own an aggregate of 3,500,000
                shares of Common Stock, which constitute approximately 16.75% of
                the total number of presently outstanding shares of Common
                Stock. Purchaser and Parent also each beneficially own the right
                to acquire up to 1,300,000 more shares of Common Stock pursuant
                to the Warrant. In addition, Purchaser and Parent each
                beneficially own 83,705 shares of Series A Preferred Stock,
                presently convertible into shares of Common Stock. Assuming the
                exercise of the Warrant and the conversion of the shares of
                Series A Preferred Stock, Purchaser and Parent would each
                beneficially own 12,409,546 shares of Common Stock, which would
                constitute approximately 59.3% of the outstanding shares of
                Common Stock.

         (b)    Purchaser and Parent share the power to vote and dispose of the
                Shares, subject to the Voting Agreement described under Item 6
                below.

         (c)    Not applicable.

         (d)    Not applicable.

         (e)    Not applicable.

ITEM 6.   CONTRACTS OR ARRANGEMENTS WITH RESPECT TO ISSUER SECURITIES.
In addition to the agreement documenting the Acquisition described in Item 4
above, Purchaser has entered into the following contracts or arrangements with
the Company and others with respect to the Company's securities:

The Series A Preferred Stock

Purchaser holds 83,705 shares of Series A Preferred Stock, which are presently
convertible at the option of the Purchaser. The shares will automatically
convert into Common Stock on December 17, 2004 or upon other specified events,
if not otherwise already converted. The conversion price at which shares of
Common Stock will be deliverable upon conversion without the payment of
additional consideration by Purchaser is $11.00 per share, subject to adjustment
for stock splits and combinations, certain dividends and distributions, and
reclassification, exchange or substitution. There is a 6% dividend payable
annually in kind on the shares of Series A Preferred Stock. Accordingly, if
Purchaser does not convert any shares prior to December 17, 2004, on such date
it would own 99,693 shares of Series A Preferred Stock as a result of the
additional shares of Series A Preferred Stock issued in payment of the 6% annual
dividend; such 99,693 shares would automatically convert into 9,063,000 shares
of Common Stock on such date.

CUSIP No. 65332H104 (Previous CUSIP No.: 927186106)
--------------------------------------------------------------------------------

The Warrant

The Warrant entitles Purchaser to purchase up to 1,300,000 shares of Common
Stock at any time prior to May 27, 2006 at 5:00 p.m. at a purchase price of
$4.60 per share, subject to adjustment from time to time in the event of cash
dividends, stock dividends, stock subdivisions, stock splits, stock combinations
or reverse stock splits. Pursuant to the Process Agreement described below,
Purchaser has agreed not to exercise the Warrant unless the Plan of Complete
Liquidation and Dissolution of the Company is not carried out as contemplated by
the Process Agreement.

Registration Rights Agreement

Purchaser and the Company are parties to a Registration Rights Agreement whereby
the Company has granted certain demand and piggyback rights to Purchaser.

Voting Agreement

Purchaser is a party to a Voting Agreement with certain other stockholders of
the Company pursuant to which all parties agree to vote all of their Common
Stock of the Company in favor of one Purchaser-nominated director. In addition,
Purchaser agrees to vote all of its Common Stock of the Company in favor of the
nominees for director recommended by the Company's nominating committee.

Relationship Restructuring

On November 24, 1999, Purchaser and the Company entered into a Put Agreement
whereby Purchaser agreed to issue Put Rights in connection with the private
placement by the Company of $63,000,000 aggregate principal amount of Series B
Preferred Stock, warrants to purchase common stock of Company, and Put Rights.
Each Put Right entitles the holder to cause Purchaser to purchase the shares of
Series B Preferred Stock during a specified time frame at a price equal to the
original purchase price of the Series B Preferred Stock plus a specified rate of
return. The Put Right is exercisable by holders at any time between November 24,
2002 and November 24, 2004, unless earlier terminated as provided in the Put
Certificate. In addition, Purchaser and the Company entered into a Side Letter
whereby the conversion price of the Series B Preferred Stock is to be adjusted
downward per the terms of the Side Letter in the event of a put to Purchaser of
the Series B Preferred Stock by the holders.

Process Agreement

On October 16, 2002 Purchaser and Parent entered into a Process Agreement with
the Company pursuant to which the Company's Board of Directors approved a Plan
of Complete Liquidation and Dissolution and Purchaser and Parent agreed that,
notwithstanding the liquidation preference of the holders of Series A Preferred
Stock and Series B Preferred Stock in the aggregate amount of approximately $151
million, the holders of the Company's common stock (other than Purchaser, Parent
and their affiliates) would be entitled to receive a cash distribution in an
amount of $0.05 per share (but not to exceed an aggregate amount of $872,026 to
all holders of our common stock). Purchaser and Parent also agreed to acquire
all of the Company's Series B Preferred Stock,

                                Page 6 of 9 Pages



together with associated warrants, from eight institutional investors. The
Series B Preferred Stock is subject to certain put rights described below
granted by Baxter International Inc. on November 24, 1999, pursuant to which
Baxter International Inc. is obligated to purchase such shares, at the option of
the holders of such shares. Purchaser and Parent also agreed to cause the
exercise of the put rights in full no later than immediately prior to the record
date for stockholder consent to the Company's Plan of Complete Liquidation and
Dissolution. In consideration of the benefits afforded to the Company and the
holders of its common stock (other than Purchaser, Parent and their affiliates)
the Company agreed to the acceleration of the exercisability of the put rights,
and, that pursuant to the terms of a Side Letter Agreement dated November 24,
1999, among Baxter International Inc., the Company and certain other parties,
the conversion price of the Series B Preferred Stock in the hands of Purchaser,
Parent and their affiliates following the exercise of the put rights would be
adjusted to a price of $0.09 per share. Purchaser and Parent agreed to cause the
conversion into common stock of the number of shares of the Series B Preferred
Stock required for Purchaser, Parent and their affiliates to hold a majority of
the outstanding shares of the Company's common stock, and further agreed to
cause the execution of a written consent approving the Company's Plan of
Complete Liquidation and Dissolution. The remaining Series B Preferred Stock and
all of the Series A Preferred Stock will not be converted to common stock and
will retain their liquidation preference, pursuant to which Purchaser, Parent
and their affiliates have the right to receive substantially all of the
Company's assets, other than the distribution of $0.05 per share of Company
common stock and other than a contingency reserve to satisfy current and
anticipated liabilities. The Process Agreement also provides that immediately
after the approval of the Board of Directors of the Company of the Plan of
Complete Liquidation and Dissolution and certain other matters, Victor W.
Schmitt will be appointed to the Board of Directors of the Company.

Except as set forth above, to the best knowledge of Purchaser and Parent, no
contracts, arrangements, understandings or relationships (legal or otherwise)
exist among the persons named in Item 2 above, or between such persons and any
other person with respect to any securities of the Company, including, but not
limited to, transfer or voting of such securities, finder's fees, joint
ventures, loan or option arrangements, puts or calls, guarantees of profits,
division of profits or loss, or the giving or withholding or proxies.
