Item 8.01         Other Events

 

On November 11, 2017, Nektar Therapeutics, a Delaware corporation (“Nektar”), issued a press release announcing interim data from the dose-escalation phase of the PIVOT-02 Phase 1/2 study, which is designed to evaluate the combination of Nektar’s CD122-biased agonist, NKTR-214, with nivolumab across several tumor types. A copy of the press release announcing these interim data is attached as Exhibit 99.1 to this Current Report on Form 8-K.

 

On November 7, 2017, Nektar, announced that it would host an analyst and investor event at the 2017 Society for Immunotherapy of Cancer Annual Meeting. The event was held on Saturday, November 11, 2017 at 6:15 p.m. Eastern Time, and included a presentation and discussion of updated clinical data for the company's CD122-biased agonist, NKTR-214.  Data from the PIVOT-02 Phase 1/2 study was reviewed at the event, as well as data from the Phase 1 dose-escalation study of NKTR-214 in combination with nivolumab in patients with melanoma, renal cell carcinoma and non-small cell lung cancer. Presenters included Dr. Patrick Hwu of MD Anderson Cancer Center, Dr. Adi Diab of MD Anderson Cancer Center, Dr. Michael E. Hurwitz of Yale Cancer Center, Dr. Antoni Ribas of UCLA Medical Center and Dr. Nizar M. Tannir of MD Anderson Cancer Center. A recording of this analyst and investor event is available for replay for two weeks on Nektar’s website, www.nektar.com

 

At the analyst and investor event, Nektar made certain forward-looking statements regarding the potential therapeutic benefit of NKTR-214 for cancer patients, the future clinical development plans for NKTR-214, the potential of NKTR-214 in combination with other immunotherapy agents including Bristol-Myers Squibb’s Opdivo (nivolumab), and certain other statements regarding the prospects and potential of Nektar’s business, technology platform and drug candidate pipeline. These forward-looking statements involve substantial risks and uncertainties, including but not limited to: (i) our statements regarding the therapeutic potential of NKTR-214 in combination with Opdivo are based on findings and observations from ongoing clinical studies and these findings and observations will evolve over time as more data emerges from the studies; (ii) NKTR-214 is in early stage clinical development and the risk of failure remains high and failure can unexpectedly occur due to efficacy, safety or other unpredictable factors; (iii) the initial preliminary RECIST response data presented at the event is subject to change—in particular, there is no way to predict whether unconfirmed responses will become confirmed responses as the clinical studies progress; (iv) the preliminary clinical results from the NKTR-214 clinical studies presented at the event remain subject to change as a result of final data audit confirmation procedures to be conducted following completion of the studies; (v) the timing of the commencement or end of clinical studies and the availability of clinical data may be delayed or unsuccessful due to regulatory delays, slower than anticipated patient enrollment, manufacturing challenges, changing standards of care, evolving regulatory requirements, clinical trial design, clinical outcomes, competitive factors, or delay or failure in ultimately obtaining regulatory approval in one or more important markets; (vi) scientific discovery of new medical breakthroughs is an inherently uncertain process and the future success of applying our technology platform to potential new drug candidates (such as NKTR-214) is therefore highly uncertain and unpredictable and one or more research and development programs could fail; (vii) patents may not issue from our patent applications for our drug candidates including NKTR-214, 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 Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on November 8, 2017. Any forward-looking statement made by Nektar at the investor and analyst event will be based only on information currently available to Nektar and speaks only as of the date on which it is made. Actual results could differ materially from the forward-looking statements made at the investor and analyst event. Nektar undertakes no obligation to update forward-looking statements whether as a result of new information, future events or otherwise.

First Data for NKTR-214 in Combination with OPDIVO® (nivolumab) for Patients with Stage IV Melanoma, Renal Cell Carcinoma and Non-Small Cell Lung Cancers, Including Patients with PD-L1 Negative Status, Revealed at SITC 2017

 

Interim data from the dose-escalation phase of the PIVOT-02 trial highlighted as an oral presentation

 

NATIONAL HARBOR, Md., Nov. 11, 2017 /PRNewswire/ -- Nektar Therapeutics (Nasdaq: NKTR) and Bristol-Myers Squibb (NYSE: BMY) today announced the first presentation of data from the PIVOT-02 Phase 1/2 Study, which is designed to evaluate the combination of Bristol-Myers Squibb's Opdivo (nivolumab) with Nektar’s investigational medicine, NKTR-214. The initial results presented at the 2017 Society for Immunotherapy of Cancer (SITC) Annual Meeting reported both safety and efficacy data for patients enrolled in the dose-escalation phase of the trial.

 

These initial findings underscore the potential benefit of the combination of Opdivo and NKTR-214 across several tumor types,” said Fouad Namouni, M.D., Head of Oncology Development, Bristol-Myers Squibb. “We believe that a combination regimen which utilizes two different, complementary, and non-overlapping mechanisms designed to harness the body's own immune system to fight cancer has the potential to benefit patients and should be the subject of additional research."

 

Opdivo is a PD-1 immune checkpoint inhibitor designed to overcome immune suppression. NKTR-214 is an investigational immuno-stimulatory therapy designed to expand and activate specific cancer-fighting T cells and natural killer (NK) cells directly in the tumor micro-environment and increase expression of cell-surface PD-1 on these immune cells.

 

In the dose-escalation stage of the PIVOT trial, we’ve observed important response rates across all three tumor types - melanoma, renal cell carcinoma and non-small lung cancer - in both PD-L1 positive and PD-L1 negative patients,” said Mary Tagliaferri, M.D., Senior Vice President of Clinical Development at Nektar Therapeutics. "All patients with responses in the trial continue on treatment. Of note, we observed responses in 3 of 4 Stage IV non-small cell lung cancer patients whose tumors did not express PD-L1 and who had progressed on prior chemotherapy, including one patient who experienced a complete response. In the combination treatment, there were no Grade 3 or higher immune-mediated adverse events at the recommended Phase 2 dose or below. Nektar and Bristol are now actively enrolling patients in the Phase 2 expansion part of the PIVOT study in 5 different tumor types."

 

A copy of the full data presentation from Dr. Diab's oral session is available on Nektar's corporate website at http://www.nektar.com/download_file/view/571 .

 

A total of 38 patients were enrolled in the dose-escalation phase of the ongoing PIVOT study in a number of dose cohorts. Responses were measured per RECIST 1.1 for efficacy-evaluable (   >   1 on treatment scan) patients as of November 2, 2017.

 

Highlights from the oral presentation include:

 

Advanced Treatment-Naïve 1L Melanoma Patients (Stage IV):

 

Responses were observed in 7/11 (63%) efficacy-evaluable patients (2 CR and 5 PR) . Median time to response was 1.7 months. DCR, also known as disease control rate (CR + PR + 3 SD), was 91%. All 7 patients with responses continue on treatment in the trial.

Advanced Treatment-Naïve 1L Renal Cell Carcinoma Patients (Stage IV):

 

For patients with one or more baseline scans, responses were observed in 6/13 patients (46%) (1 CR + and 5 PR). DCR (CR + PR + 5 SD) was 85%. Median time to response in these patients was 1.9 months. For patients with two or more scans available, responses were observed in 6/10 patients (60%) (1 CR, 5 PR, 2 SD). All 11 patients with disease control (CR, PR or SD) continue on treatment in the trial.

Advanced 2L Renal Cell Carcinoma Patients (Stage IV, I-O Naïve)

For patients with one or more baseline scans, responses were observed in 1/7 patients (14%) (1 PR). DCR (CR + PR + 6 SD) was 100%. Median time to response was 3.5 months. All 7 patients with disease control (PR or SD) continue on treatment in the trial.

 

 

 

 

Advanced 2L PD-L1 Negative Non-Small Cell Lung Cancer Patients (Stage IV, I-O Naïve)

Responses were observed in 3/4 patients (75%) (1 CR ± and 2 PR). DCR (CR + PR) was 75%. Median time to response was 1.7 months. All 3 patients with responses continue on treatment in the trial.

Robust expansion of ICOS+ CD4 and CD8+ T cells in the blood and increased ICOS gene expression in the tumor were both observed with the combination of NKTR-214 and nivolumab.

The most common grade 1-2 adverse events were fatigue (74%), flu-like symptoms (68%), rash (60%) and pruritus (42%). There were no treatment discontinuations due to adverse events (AEs) or study deaths.

There were no grade 3 or higher immune-mediated AEs (such as colitis, dermatitis, hepatitis, pneumonitis or endocrinopathies) at the recommended Phase 2 dose or below

A recommended Phase 2 dose of NKTR-214 0.006 mg/kg q3w + nivolumab 360 mg q3w was established and is being evaluated in expansion cohorts in over 10 patient populations with melanoma, renal cell carcinoma, non-small cell lung cancer, bladder, and triple-negative breast cancers (n=~330).

 

Nektar and Bristol-Myers Squibb entered into a clinical collaboration in September of 2016 to evaluate the potential for the combination of Opdivo and NKTR-214 to show improved and sustained efficacy and tolerability above the current standard of care. Bristol-Myers Squibb and Nektar are equally sharing costs of the combined therapy trials. Nektar maintains its global commercial rights to NKTR-214.

 

NKTR-214 preferentially binds to the CD122 receptor on the surface of cancer-fighting immune cells in order to stimulate their proliferation. In clinical and preclinical studies, treatment with NKTR-214 resulted in expansion of these cells and mobilization into the tumor micro-environment. 1,2,3 NKTR-214 has an antibody-like dosing regimen similar to the existing checkpoint inhibitor class of approved medicines.

 

◊ One patient with confirmed PR at last scan experienced an unconfirmed CR, there was one additional patient with unconfirmed PR in the melanoma cohort as of Nov 2, 2017.

+ Complete response is unconfirmed, patient has confirmed PR.

± Complete response is unconfirmed, patient has confirmed PR.

IMPORTANT SAFETY INFORMATION

 

WARNING: IMMUNE-MEDIATED ADVERSE REACTIONS

 

YERVOY can result in severe and fatal immune-mediated adverse reactions. These immune-mediated reactions may involve any organ system; however, the most common severe immune-mediated adverse reactions are enterocolitis, hepatitis, dermatitis (including toxic epidermal necrolysis), neuropathy, and endocrinopathy. The majority of these immune-mediated reactions initially manifested during treatment; however, a minority occurred weeks to months after discontinuation of YERVOY.

 

Assess patients for signs and symptoms of enterocolitis, dermatitis, neuropathy, and endocrinopathy and evaluate clinical chemistries including liver function tests (LFTs), adrenocorticotropic hormone (ACTH) level, and thyroid function tests at baseline and before each dose.

 

Permanently discontinue YERVOY and initiate systemic high-dose corticosteroid therapy for severe immune-mediated reactions.

Immune-Mediated Encephalitis

 

OPDIVO can cause immune-mediated encephalitis. Evaluation of patients with neurologic symptoms may include, but not be limited to, consultation with a neurologist, brain MRI, and lumbar puncture. Withhold OPDIVO in patients with new-onset moderate to severe neurologic signs or symptoms and evaluate to rule out other causes. If other etiologies are ruled out, administer corticosteroids and permanently discontinue OPDIVO for immune-mediated encephalitis. In patients receiving OPDIVO monotherapy, encephalitis occurred in 0.2% (3/1994) of patients. Fatal limbic encephalitis occurred in one patient after 7.2 months of exposure despite discontinuation of OPDIVO and administration of corticosteroids. Encephalitis occurred in one patient receiving OPDIVO with YERVOY (0.2%) after 1.7 months of exposure.

 

Other Immune-Mediated Adverse Reactions

 

Based on the severity of the adverse reaction, permanently discontinue or withhold OPDIVO, administer high-dose corticosteroids, and, if appropriate, initiate hormone-replacement therapy. Across clinical trials of OPDIVO monotherapy or in combination with YERVOY, the following clinically significant immune-mediated adverse reactions, some with fatal outcome, occurred in < 1.0% of patients receiving OPDIVO: myocarditis, rhabdomyolysis, myositis, uveitis, iritis, pancreatitis, facial and abducens nerve paresis, demyelination, polymyalgia rheumatica, autoimmune neuropathy, Guillain-Barré syndrome, hypopituitarism, systemic inflammatory response syndrome, gastritis, duodenitis, sarcoidosis, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), motor dysfunction, vasculitis, and myasthenic syndrome.

 

Infusion Reactions

 

OPDIVO can cause severe infusion reactions, which have been reported in < 1.0% of patients in clinical trials. Discontinue OPDIVO in patients with Grade 3 or 4 infusion reactions. Interrupt or slow the rate of infusion in patients with Grade 1 or 2. In patients receiving OPDIVO monotherapy, infusion-related reactions occurred in 6.4% (127/1994) of patients. In patients receiving OPDIVO with YERVOY, infusion-related reactions occurred in 2.5% (10/407) of patients.

 

 

 

 

Complications of Allogeneic HSCT after OPDIVO

 

Complications, including fatal events, occurred in patients who received allogeneic HSCT after OPDIVO. Outcomes were evaluated in 17 patients from Checkmate 205 and 039, who underwent allogeneic HSCT after discontinuing OPDIVO (15 with reduced-intensity conditioning, 2 with myeloablative conditioning). Thirty-five percent (6/17) of patients died from complications of allogeneic HSCT after OPDIVO. Five deaths occurred in the setting of severe or refractory GVHD. Grade 3 or higher acute GVHD was reported in 29% (5/17) of patients. Hyperacute GVHD was reported in 20% (n=2) of patients. A steroid-requiring febrile syndrome, without an identified infectious cause, was reported in 35% (n=6) of patients. Two cases of encephalitis were reported: Grade 3 (n=1) lymphocytic encephalitis without an identified infectious cause, and Grade 3 (n=1) suspected viral encephalitis. Hepatic veno-occlusive disease (VOD) occurred in one patient, who received reduced-intensity conditioned allogeneic HSCT and died of GVHD and multi-organ failure. Other cases of hepatic VOD after reduced-intensity conditioned allogeneic HSCT have also been reported in patients with lymphoma who received a PD-1 receptor blocking antibody before transplantation. Cases of fatal hyperacute GVHD have also been reported. These complications may occur despite intervening therapy between PD-1 blockade and allogeneic HSCT.

 

Follow patients closely for early evidence of transplant-related complications such as hyperacute GVHD, severe (Grade 3 to 4) acute GVHD, steroid-requiring febrile syndrome, hepatic VOD, and other immune-mediated adverse reactions, and intervene promptly.

Based on their mechanisms of action, OPDIVO and YERVOY can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with an OPDIVO- or YERVOY- containing regimen and for at least 5 months after the last dose of OPDIVO.

 

Lactation

 

It is not known whether OPDIVO or YERVOY is present in human milk. Because many drugs, including antibodies, are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from an OPDIVO-containing regimen, advise women to discontinue breastfeeding during treatment. Advise women to discontinue nursing during treatment with YERVOY and for 3 months following the final dose.

Nektar Cautionary Note Regarding Forward-Looking Statements

 

This press release contains forward-looking statements which can be identified by words such as: "anticipate," "intend," "design," "expect," "believe," "should," "may," "will" and similar references to future periods. Examples of forward-looking statements include, among others, statements we make regarding the therapeutic potential of NKTR-214 in combination with Opdivo, observations from early data emerging from ongoing clinical trials of NKTR-214, and the potential of our technology and drug candidates in our research and development pipeline. Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on our current beliefs, expectations and assumptions regarding the future of our business, future plans and strategies, anticipated events and trends, the economy and other future conditions. Because forward-looking statements relate to the future, they 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. Therefore, you should not rely on any of these forward-looking statements. Important factors that could cause our actual results to differ materially from those indicated in the forward-looking statements include, among others: (i) our statements regarding the therapeutic potential of NKTR-214 in combination with Opdivo are based on findings and observations from ongoing clinical studies and these findings and observations will evolve over time as more data emerges from the studies; (ii) NKTR-214 is in early stage clinical development and the risk of failure remains high and failure can unexpectedly occur due to efficacy, safety or other unpredictable factors; (iii) the initial preliminary RECIST response data reported in this press release is subject to change—in particular, there is no way to predict whether unconfirmed responses will become confirmed responses as the clinical studies progress; (iv) the preliminary clinical results from the NKTR-214 clinical studies described in this press release remain subject to change as a result of final data audit confirmation procedures to be conducted following completion of the studies; (v) the timing of the commencement or end of clinical studies and the availability of clinical data may be delayed or unsuccessful due to regulatory delays, slower than anticipated patient enrollment, manufacturing challenges, changing standards of care, evolving regulatory requirements, clinical trial design, clinical outcomes, competitive factors, or delay or failure in ultimately obtaining regulatory approval in one or more important markets; (vi) scientific discovery of new medical breakthroughs is an inherently uncertain process and the future success of applying our technology platform to potential new drug candidates (such as NKTR-214) is therefore highly uncertain and unpredictable and one or more research and development programs could fail; (vii) patents may not issue from our patent applications for our drug candidates including NKTR-214, 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 Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on November 8, 2017. 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, whether written or oral, that may be made from time to time, whether as a result of new information, future developments or otherwise.
