Analyst · JP Morgan. Your line is open
Thank you, Jennifer, and thank you to everyone for joining us today for our second quarter conference call. On today's call, we will discuss many upcoming milestones for Nektar's pipeline throughout the end of the year including comprehensive data presentations for NKTR-181 at PAINWEEK in early September and for NKTR-214 at $WIFI. We will also update our financial guidance for the remainder of 2017, which incorporates the recent Lilly collaboration for NKTR-358. Nektar is having a highly successful 2017 with a number of notable recent accomplishments. First, we announced positive data from our human abuse potential trial for NKTR-181 which builds on the overwhelmingly positive Phase 3 efficacy and safety data for NKTR-181 that we announced in the first quarter. NKTR-181 is an important potential medicine that is capturing a lot of attention because of its promise to both address opioid abuse epidemic and advance the treatment of pain. I’ll talk more about our excitement for NKTR-181 in our next steps in a moment. Second, we recently entered into a collaboration with Lilly for Nektar 358, our first-in-class Treg stimulator, which is in development for the treatment of immune and inflammatory disorders. And I will discuss more about the importance of this new partnership in a moment. Third, we are very excited about our emerging data from the PIVOT study for NKTR-214 in combination with nivolumab. And I’ll update you on our progress with that trial. I’ll start with our new collaboration for NKTR-358 with Lilly. Lilly is a strong leader in immunology and this collaboration enables the broad and parallel development of NKTR-358 in multiple autoimmune conditions, so we can ensure that it has full potential as a first-in-class resolution therapeutic. The collaboration allows Nektar to retain a very significant ownership interest in NKTR-358 with substantial royalties for a program with multi-billion dollar commercial potential and an option to co-promote. The Phase 1 program for NKTR-358 is underway and Jonathan will talk more about the development program later. NKTR and Lilly share a broad development vision for NKTR358, which includes evaluating a minimum of four different autoimmune conditions in the clinic. Lilly is paying Nektar an initial upfront payment of $150 million and in addition, we will receive up to $250 million in development and regulatory milestones through various phases of development success and regulatory approval. For Phase 2 and Phase 3, Lilly will cover 75% of development costs and our royalty rates will start in the mid-teens and reach the low-20s when NKTR-358 achieves $500 million in annual global sales. So in essence, Nektar is funding a quarter of the developments in retaining a one-third ownership of the drug. Lilly is responsible for all costs of global commercialization. Nektar also has the option to co-promote in the United States. We are very proud and excited about the scale and breadth of this significant partnership with Lilly. Lilly clearly recognizes that NKTR-358 is a potential breakthrough in treating autoimmune disease and NKTR-358 highlights both the innovative nature of our research and our demonstrated ability to discover important new medicines. Moving on to NKTR-214, I am extremely pleased to announce that Nektar and Bristol recently began enrolling patients into the expansion cohorts in the Phase 2 stage of the PIVOT trial across multiple tumor indications. I’ll let Mary talk more about PIVOT in a moment, as the T-cell growth factor NKTR-214 provides an important new mechanism in immune oncology. We are very excited about the emerging data from the PIVOT trial and we plan to share these data with you at the upcoming SITC Meeting in November. As you know, our objective is to position NKTR-214 as a keystone therapeutic in IO. It is very important to note that NKTR-214 can be combined with many other agents having different mechanisms and in different cancer settings with synergistic efficacy and non-overlapping toxicities to improve patient outcomes. Jonathan will discuss the ongoing preclinical work on this front including the recently announced collaboration with Takeda. As you know, in addition to NKTR-214, Nektar is developing a broad portfolio in immune oncology. Our portfolio also includes NKTR-262, a TLR agonist and NKTR-255, an IL 15 candidate, which can stimulate both NK cells and memory T-cells. The preclinical data for the NKTR-214, 262 combo are particularly compelling and we plan to file the IND for the combination trial of NKTR-262 and NKTR-214 this year. As a novel small molecule TLR agonist, NKTR-262 was designed specifically to be administered with NKTR-214 and most importantly, would give Nektar our first wholly-owned combination regimen in IO. Jonathan will discuss more on NKTR-262 later in the call. Importantly, let’s now move on to discuss NKTR-181, which is emerging as a critically important new potential medicine to treat patients with moderate to severe chronic pain. The opioid abuse and addiction epidemic has clearly become a central focus of the FDA, Congress and the White House and is one of the few truly Bipartisan issues facing our country and as we’ve heard from our discussions with all of these stakeholders. As the first new full new opioid agonist molecule, to be developed in over 50 years, NKTR-181’s unique inherent properties position the drug to not only help stem the rate of new addiction with conventional opioids, but also to reduce diversion of prescription in pain medicines for abuse. When measuring abuse potential, the analgesic doses established in the SUMMIT-07 study were comparable to placebo and much less like than oxycodone in two separate human abuse studies. We’ve also established that NKTR-181 has a well-tolerated safety profile in our 52-week long-term safety study. We now have an extensive amount of efficacy and safety data for NKTR-181 in over 2000 patients and healthy subjects. NKTR-181 is a new molecule, clearly addresses the rapid rate of brain entry which underlies euphoria as well as many of the negative side-effects of conventional opioids. Our extensive pharmacokinetic clinical work with NKTR-181 demonstrates that it is a highly predictable and well-characterized 12-hour terminal half-life regardless of formulation, tablet or solutions. This unique PK and resulting PD profile is important for two reasons. First, it provides full pain relief coverage over a 12-hour period, so there is no need for augmentation with immediate release opioids and second, it addresses the problem raised by the shorter half-life of some controlled release formulations of conventional opioids that is, the emergence of withdraw symptoms several hours before the end of the dosing period. This is sometimes called micro withdrawal and can drive an overwhelming craving to redoes ahead of schedule. For conventional opioid, the combination of high likeability in euphoria, coupled with micro withdrawal effects, prior to taking the next dose can be very strongly reinforcing and therefore dangerous in the context of generating misuse leading to addiction. At PAINWEEK in early September, we plan to present additional data from the SUMMIT-07 trial measuring these metrics of withdrawal. These important new data support that NKTR-181 is a truly unique pain medicine that is not associated with even moderate withdrawal symptoms, either while patients are on treatment or as they come off-treatments. The comprehensive NKTR-181 data established the potency of its analgesics, its low abuse potential, its favorable safety and physical dependency profile, and the strength of its molecular structure which can’t be tampered with broken or converted into a rapid-acting euphorigenic opioid form. We will review our data for NKTR-181 with the agency in the fourth quarter of this year to discuss the potential for an NDA filing based upon the data from our single Phase 3 efficacies trial, our HAP studies and our comprehensive long-term safety study. As a reminder, we have fast-track designation for NKTR-181, if we are given the green light by the FDA the Nektar team is prepared to move forward quickly with a rolling NDA submission in the early part of 2018. We also remain committed to establishing a partnership for NKTR-181 this year in order to allow us to bring this important new medicine to patients as quickly as possible and to maximize value for our shareholders. Now let me turn the call to Mary to update you on NKTR-214 and the PIVOT program.
