past year was truly transformational for Nektar as we achieved a number of successes with Nektar medicines across our three key
therapeutic areas of immuno-oncology, immunology and pain,&rdquo; said Howard W. Robin, President and Chief Executive Officer
of Nektar. &ldquo;In the area of pain, we completed a successful Phase 3 program for NKTR-181 in over 2,100 patients and healthy
volunteers that will comprise our NDA submission in the second quarter of this year. In immunology, we entered into a major partnership
with Eli Lilly for NKTR-358, a potential first-in-class T regulatory resolution therapeutic, which will be developed to treat
a broad range of auto-immune disorders. Finally, in immuno-oncology, the clinical success we achieved with NKTR-214 led to a groundbreaking
collaboration with Bristol-Myers Squibb that now enables us to broadly and rapidly advance NKTR-214 into over 20 registrational
trials in up to 15,000 patients.&rdquo;</FONT></P>

Note Regarding Forward-Looking Statements</B><BR>
<I>This press release contains uncertain or forward-looking statements which can be identified by words such as: &ldquo;could,&rdquo;
&ldquo;plan,&rdquo; &ldquo;expect,&rdquo; &ldquo;prepare,&rdquo; &ldquo;may,&rdquo; &ldquo;will&rdquo; and similar references
to future periods. Examples of forward-looking statements include, among others, statements we make regarding the potential therapeutic
benefits of and future development plans for our products (including NKTR-214, NKTR-181, NKTR-358, NKTR-262 and NKTR-255), the
potential impact of NKTR-181 with respect to the opioid abuse epidemic, the timing and strategy for regulatory filings (including
the timing and strategy for filing a new drug application, &ldquo;NDA&rdquo;), and the results of clinical trials. Forward-looking
statements are neither historical facts nor assurances of future performance. Instead, they are based only on our current beliefs,
expectations and assumptions and are subject to inherent uncertainties, risks and changes in circumstances that are difficult
to predict and many of which are outside of our control. Our actual results may differ materially from those indicated in the
forward-looking statements and you should not rely on such statements. Important factors that could cause our actual results to
differ materially from those indicated in the forward-looking statements include: (i) clinical study outcomes remain very unpredictable
and it is possible that a clinical study could fail even after positive interim data is observed; (ii) the regulatory pathway
to review and approve pharmaceutical products is subject to substantial uncertainty; (iii) the data package required for filing
and approval of an NDA to the FDA is very uncertain and difficult to predict due to broad FDA regulatory discretion, and changing
FDA regulatory guidelines; (iv) the final outcomes and conclusions from sponsor meetings with FDA are subject to substantial FDA
discretion associated with issuing final meeting minutes and outcomes; (v) regulations concerning and controlling access to opioid-based
pharmaceuticals are strict and it is difficult to predict which scheduling category will apply to NKTR-181 if regulatory approval
is achieved; (vi) the timing of regulatory approval for the recently announced strategic collaboration agreement with Bristol-Myers
Squibb is uncertain; (vii) patents may not issue from our patent applications for our drug candidates, patents that have issued
may not be enforceable, or additional intellectual property licenses from third parties may be required; and (viii) certain other
important risks and uncertainties set forth in our Annual Report on Form 10-K filed with the Securities and Exchange Commission
on March 1, 2018. Any forward-looking statement made by us in this press release is based only on information currently available
to us and speaks only as of the date on which it is made. We undertake no obligation to update any forward-looking statement.</I></FONT></P>
