Item 8.01 Other Events.

Research Foundation of the State University of New York (“SUNY”) Litigation

On December 20, 2013, Nektar Therapeutics (“Nektar”) entered into a Settlement Agreement and Release (the “Settlement”) with SUNY, relating to the previously announced action filed by SUNY against Nektar on November 18, 2009 in the United States District Court for the Northern District of New York to recover amounts SUNY alleged it is owed pursuant to a technology licensing contract between Nektar and SUNY, as previously discussed in Nektar’s most recent Annual Report on Form 10-K and subsequent Quarterly Reports on Form 10-Q previously filed with the Securities and Exchange Commission (the “SEC”).

Under the terms of the Settlement, SUNY agreed to dismiss the action with prejudice and relinquish all rights it may have had to a portion of future development and regulatory milestone payments payable to Nektar under the Co-Development, License and Co-Promotion Agreement, dated August 1, 2007, between Nektar (and its subsidiaries) and Bayer Healthcare LLC, as amended, related to the inhaled amikacin program in exchange for (i) a $5 million payment due on April 1, 2014; (ii) a $5 million payment due on January 1, 2015, (iii) a series of four $500,000 payments each due on April 1, 2014, January 1, 2015, January 1, 2016, and January 1, 2017, respectively; and (iv) certain other terms and conditions.

Presentation at the J.P. Morgan 2014 Healthcare Conference

On January 14, 2014, Howard W. Robin, the President and Chief Executive Officer of Nektar, participated in the J.P. Morgan 2014 Healthcare Conference. A copy of the presentation slides used at the conference are attached as Exhibit 99.1 to this Current Report on Form 8-K and are incorporated herein by reference.

As part of the presentation, Mr. Robin announced that based upon preliminary estimates, as of December 31, 2013, Nektar had cash and investments in marketable securities of approximately $262 million, which amount includes $25 million in restricted cash as well as a previously disclosed $70 million milestone payment paid by AstraZeneca PLC (“AstraZeneca”) to Nektar in November 2013 under the terms of a license agreement, dated September 20, 2009, as amended, between AstraZeneca and Nektar. The $70 million milestone payment would be recognized as revenue by Nektar upon the earlier to occur of approval by the U.S. Food and Drug Administration (the “FDA”) of naloxegol or AstraZeneca receiving a complete response letter from the FDA which does not include a requirement for a pre-approval cardiovascular safety study that is reasonably expected to exceed $70 million in external costs to complete. For other important terms and conditions related to the $70 million milestone payment, please refer to Item 1.01 of the Current Report on Form 8-K filed by Nektar with the SEC on August 8, 2013.

This financial information has been prepared by and is the responsibility of Nektar’s management and has not been reviewed or audited by Nektar’s independent registered public accounting firm, and, accordingly, Nektar’s independent registered public accounting firm does not express an opinion on or provide any other form of assurance with respect to this preliminary data. This financial information is subject to completion of Nektar’s year-end financial closing procedures, the preparation of Nektar’s financial statements, and the completion of the audit of Nektar’s financial statements as of and for the year ended December 31, 2013, and Nektar’s actual results may differ from these estimates.

Opioid-Induced Constipation:

High Unmet Medical Need

$14.8 Billion

Of the $14.8 billion global opioid market, five markets account for ~80% of total unit volume: US (49%), UK (14%), Germany (5%), Canada (5%), France (5%).1 PCPs and Pain Management Specialists comprise the majority of prescribers in these markets.2

69 Million Patients

In these five markets, there are 69 million patients taking opioids for chronic pain (>30 days treatment).3 For these chronic pain opioid users, opioid induced constipation (OIC) is the most common side effect.4,5

28—35 Million Patients

Approximately 40-50% (28-35 million) patients taking opioids for chronic pain develop constipation.1,2,3* More than 50% of these patients do not get relief from laxatives.

Naloxegol: Positive Results from Long-Term 52-Week Comparative Safety Study

Large, well-controlled, 52-week, randomized (2:1), open-label safety study (KODIAC 08) compared chronic administration naloxegol to usual care (UC)

534 patients – naloxegol 25 mg

270 patients – usual care

Most common GI-related AEs occurring more frequently in naloxegol arm were abdominal pain, diarrhea, and nausea No increases in mean pain scores and mean opioid doses in the study No imbalance in serious adverse events, including major adverse CV events (MACE)

2 MACE events out of 534 patients – naloxegol 25 mg

2 MACE events out of 270 patients – usual care

No reports of opioid withdrawal AEs attributable to naloxegol

Prospective assessment of opioid withdrawal using modified Himmelsbach scale (MHS) showed no notable differences in mean change from baseline in scores between arms

Reasons for Lack of Placebo Rebound

EERW design not optimal for a unique drug like NKTR-181 with low CNS side effects

EERW design adopted to study opioids with tolerability issues and high CNS side effects: typical drop-out rates >50%

NKTR-181 drop-out rate for AEs was only 18% because of low CNS side effects

With typical opioids, patients may be un-blinded when crossed to placebo in the EERW design because of removal of CNS side effects. The result is a significantly diminished placebo effect and a resulting rebound in pain scores.

Subjects were allowed to continue using their current non-opioid pain medications

NKTR-181 provided strong analgesia in titration, with 40% reduction of pain from baseline

This reduction at time of randomization allowed the background analgesics to maintain pain relief during the 3 week double-blind period, which prevented significant rebound.

WOMAC pain subscale is more reliable measurement than NRS

Next Step for NKTR-181:

Guidance from FDA and Key Pain Experts

Highly productive initial meeting with FDA under Fast

Track Status

First Phase 3 study can be started this year in patients with OA

Parallel design suitable for pivotal registration studies

No requirement to use EERW for registration

NKTR-181 is clearly an analgesic with a superior tolerability profile than other opioids

Recommend continued development in OA

Acute Pain Programs

Phase 1 Multiple-Ascending Dose Study for NKTR-192

NKTR-192 demonstrated significant and rapid analgesic effect At the highest 200 mg dose, analgesic activity was superior to 20 mg of IR oxycodone NKTR-192 also exhibited low CNS side effects with low levels of sedation and dizziness and no reports of euphoria or elevated mood Elevated liver enzymes were observed in some patients at highest dose, which are hypothesized to be caused by metabolites from oral first pass metabolism
