The CLEP approval makes clonoSEQ testing accessible to patients in New York who have been diagnosed with B-cell cancers, a subset of lymphoid cancers that includes ALL, multiple myeloma, chronic lymphocytic leukemia (CLL) and B-cell non-Hodgkin’s lymphoma (NHL). Testing under CLEP may be performed using DNA from bone marrow, blood and archived tissue samples. With this approval, clonoSEQ MRD testing is now available in all 50 states and has a considerable and growing payor footprint (>140MM covered lives to date).

"New York State CLEP approval for clonoSEQ means patients in New York can now work with their cancer care team to incorporate clonoSEQ into their treatment regimen to accurately and reliably assess and monitor their disease over time, using multiple sample types, including blood samples," said, Chad Robins, CEO and co-founder, Adaptive Biotechnologies. "This rigorous approval also supports our ongoing work to expand access to patients and our pursuit of FDA authorization for new indications for clonoSEQ in other lymphoid cancers and sample types."

clonoSEQ has been ordered by clinicians in nearly 300 healthcare systems and institutions, including 27 of the 28 NCCN centers in the United States, and used by more than 30 biopharmaceutical companies in over 120 clinical trials.

"The approval gives patients in New York access to the standardized, FDA-cleared clinical MRD testing that is already being utilized throughout the rest of the country," said Dr. Ajai Chari, Associate Professor of Medicine, Hematology and Medical Oncology at The Tisch Cancer Institute at Mount Sinai, who was a past consultant for the clonoSEQ Assay.

About the clonoSEQ Assay

The clonoSEQ assay was granted de novo designation and marketing authorization by FDA for the detection and monitoring of minimal residual disease (MRD) in patients with multiple myeloma (MM) and B-cell acute lymphoblastic leukemia (ALL) using DNA from bone marrow samples. clonoSEQ is the first and only FDA-authorized in vitro diagnostic assay for MRD testing. It is also the first clinical diagnostic powered by immunosequencing to receive FDA clearance. clonoSEQ leverages Adaptive’s proprietary immunosequencing platform to identify and quantify specific DNA sequences found in malignant cells, allowing clinicians to assess and

monitor MRD during and after treatment. The assay provides standardized, accurate and sensitive measurement of MRD that allows physicians to predict patient outcomes, assess response to therapy over time, monitor patients during remission and detect potential relapse. Clinical practice guidelines in hematological malignancies recognize that MRD status is a reliable indicator of clinical outcomes and response to therapy, and clinical outcomes are strongly associated with MRD levels measured by the clonoSEQ Assay in patients diagnosed with ALL and MM. clonoSEQ testing is covered by Medicare and an expanding list of private payors in alignment with the FDA label.

clonoSEQ is a single-site assay performed at Adaptive Biotechnologies. It is also available as a CLIA-regulated laboratory developed test (LDT) service for use in other lymphoid cancers. For important information about the FDA-cleared uses of clonoSEQ, including the full intended use, limitations, and detailed performance characteristics, please visit www.clonoSEQ.com/technical-summary.

"We continue to execute on accelerating and expanding our robust, late-stage innovative clinical development programs, as we invest in forward integration across our organization to maximize value. Efgartigimod is the most advanced and also the broadest FcRn antagonist program with four indications and both intravenous and subcutaneous formulations. Enrollment for the Phase 3 ADAPT trial in generalized myasthenia gravis is progressing as planned and we are on track to initiate before the end of the year the first of two pivotal Phase 3 trials, ADVANCE, for our global primary immune thrombocytopenia program, as well as a Phase 2 trial in chronic inflammatory demyelinating polyneuropathy. Our Phase 2 trial of efgartigimod in pemphigus vulgaris remains a priority, and we expect to report topline data in the first half of 2020," commented Tim Van Hauwermeiren, CEO of argenx. "As we move towards becoming a fully-integrated biotechnology company, we continue to invest in commercial infrastructure with the build-out of our neuromuscular and hematology franchises and the expansion of our global supply chain through our longstanding collaboration with Lonza, which is expected to support the commercial launch of efgartigimod in generalized myasthenia gravis in 2021."

SECOND QUARTER 2019 AND RECENT HIGHLIGHTS

During its 2019 R&D Day in May, argenx announced its plan to become a fully integrated, global immunology company in accordance with its "argenx 2021" vision, which includes building two successful commercial franchises in neuromuscular and hematological disorders.

Efgartigimod (ARGX-113): Potential to be best-in-class with broad applicability

Efgartigimod is a human IgG1 Fc fragment engineered to increase affinity for FcRn versus endogenous IgG, whilst preserving characteristic pH-dependent binding, which may contribute to efgartigimod’s relatively long serum half-life and pharmacodynamic effect, and may promote tissue penetration. Treatment with efgartigimod results in a targeted reduction of IgG autoantibodies and is a rational approach to diseases where IgGs are directly pathogenic. argenx is evaluating efgartigimod as a potential treatment for four high-value indications, including:

Generalized Myasthenia Gravis (gMG)

Global, multi-center Phase 3 ADAPT clinical trial, including ADAPT+ one-year open-label extension study, currently ongoing

With current enrollment on track, topline data are expected in second half of 2020

Results from completed Phase 2 clinical trial were published in Neurology

Primary Immune Thrombocytopenia (ITP)

Global Phase 3 program to include two registration trials that will be run concurrently

First trial (ADVANCE) to evaluate 10 mg/kg intravenous (IV) efgartigimod on top of standard of care medication, with enrollment up to 158 patients; primary endpoint includes achieving sustained platelet count response of at least 50×109/L

Second trial to evaluate 10 mg/kg IV induction period followed by subcutaneous (SC) injections, all on top of standard of care medication, to evaluate potential of SC product to maintain clinical benefit

Phase 3 program was developed following consultation with key regulatory agencies

ADVANCE Phase 3 clinical trial expected to start in second half of 2019

Pemphigus Vulgaris (PV)

Phase 2 proof-of-concept clinical trial ongoing and currently enrolling patients in third cohort with extended dosing of efgartigimod

Data from Phase 2 clinical trial expected in first half of 2020

Chronic Inflammatory Demyelinating Polyneuropathy (CIDP)

Phase 2 clinical trial on track to start in second half of 2019

Key opinion leader (KOL) event planned for fourth quarter 2019 to discuss Phase 2 trial design and unmet needs in CIDP

argenx entered into a global collaboration with Halozyme in February 2019 to develop a SC formulation of efgartigimod using Halozyme’s proprietary ENHANZE drug delivery technology, gaining exclusive rights to the technology for the FcRn target.

First subject dosed in Phase 1 healthy volunteer (HV) trial evaluating safety, pharmacokinetics, pharmacodynamics and bioavailability of ENHANZE SC formulation of efgartigimod

Initiation of study triggered $5 million milestone payment to Halozyme

Data from Phase 1 HV trial are expected by end of 2019 after which argenx will disclose a path forward in patients for ENHANZE SC formulation of efgartigimod

Cusatuzumab (ARGX-110): First-in-class opportunity in acute myeloid leukemia (AML)

Cusatuzumab is a first-in-class monoclonal antibody inhibiting CD70, a target that is uniquely present on both leukemic stem cells and AML blasts but not healthy cells. It is being developed under an exclusive global collaboration and license agreement with Janssen for the treatment of AML, high-risk myelodysplastic syndromes and other hematological malignancies.

Phase 2 and registration-directed clinical trial in AML on track to start in second half of 2019

Trial to enroll up to 150 patients with previously untreated AML and who are not eligible for intensive chemotherapy

In this two-part trial, patients will first be randomized to receive one of two dose levels of cusatuzumab (10 mg/kg and 20 mg/kg) in combination with azacytidine (75 mg/m2) followed by an expansion cohort to evaluate efficacy of the selected dose of cusatuzumab

Early Development Programs

argenx announced during its R&D Day the expansion of its product pipeline with the addition of two new proprietary therapeutic candidates, ARGX-117 and ARGX-118. Both emerged from argenx’s Innovative Access Program, in which it collaborates closely with disease biology experts, bringing the argenx cutting-edge antibody discovery and engineering technologies to the heart of novel target research.

ARGX-117 is a complement-targeting antibody against C2, a component of both the classical and lectin pathways in the complement cascade

Potential therapeutic applications in multiple autoimmune diseases

argenx exercised its second exclusive license to Halozyme’s ENHANZE technology for use with this molecule

Expected to file Clinical Trial Application (CTA) by end of 2019 with first-in-human trial expected to start in first quarter of 2020

ARGX-118 is a highly differentiated antibody against Galectin-10, the protein of Charcot-Leyden crystals (CLCs), which play a major role in severe asthma and the persistence of mucus plugs

Immunology breakthrough in airway inflammation

SIMPLE Antibody observed to have unique crystal-dissolving properties

Currently in final stages of lead optimization work

Data were published in Science by argenx collaborator Dr. Bart Lambrecht from VIB Inflammation Research Center supporting role of CLCs and potential of ARGX-118 in airway inflammation

Corporate Update

Appointed Wim Parys, M.D. as Chief Medical Officer effective July 1, 2019. Most recently, Dr. Parys served as Head of R&D of the Global Public Health group of Janssen.

HALF YEAR 2019 FINANCIAL RESULTS (CONSOLIDATED)

On June 30, 2019, cash, cash equivalents and current financial assets totaled €944.3 million, compared to €564.6 million on December 31, 2018. The increase in cash, cash equivalents and current financial assets resulted primarily from the closing of the exclusive global collaboration and license agreement for cusatuzumab with Janssen which resulted in a $300 million upfront payment and a $200 million equity investment in January 2019.

Total operating income increased by €30.8 million for the six months ended June 30, 2019 to reach €51.3 million, compared to €20.5 million for the six months ended June 30, 2018. The increase is primarily related to (i) a €16.0 million increase in the recognition of milestone payments following the initiation of a first-in-human clinical trial with ABBV-151 (formerly named ARGX-115) under the AbbVie collaboration, which triggered a $30 million milestone payment, (ii) an increase of €7.8 million related to the recognition of research and development service fees under the Janssen collaboration and (iii) an increase of €5.2 million, mainly driven by higher payroll tax rebates for employing certain research and development personnel.

Research and development expenses totaled €78.3 million and €34.4 million for the six months ended June 30, 2019 and 2018 respectively. The increase in the first six months of 2019 resulted primarily from higher external research and development expenses and personnel expenses, reflecting higher clinical trials costs and manufacturing expenses related to the development of argenx’s product candidate portfolio and the recruitment of additional employees to support research and development activities.

Selling, general and administrative expenses totaled €27.5 million and €11.5 million for the six months ended June 30, 2019 and 2018, respectively. The increase of €16.0 million in selling, general and administrative expenses for the six months ended June 30, 2019 primarily resulted from higher personnel expenses and consulting fees related to the preparation of a possible future commercialization of argenx’s lead product candidate efgartigimod.

For the six months ended June 30, 2019, financial income amounted to €7.2 million, compared to €1.3 million for the six months ended June 30, 2018. The increase of €5.9 million in the first six months of 2019 related primarily to an increase in the interest received on cash, cash equivalents and current financial assets.

Exchange gains totaled €2.5 million for the six months ended June 30, 2019, compared to the €4.0 million for the six months ended June 30, 2018 and were mainly attributable to unrealized exchange rate gains on argenx’s cash and current financial assets position in U.S. Dollars due to the favorable fluctuation of the EUR/USD exchange rate in the first six months of 2019.

The total comprehensive loss for the six months ended June 30, 2019 was €45.1 million, compared to €20.1 million for the six months ended June 30, 2018.

The 90 day average number of shares outstanding per June 30, 2019 was 38,026,040.

Financial Outlook

Based on the current objectives of the Company’s business plan, argenx expects that its existing cash, cash equivalents and investments will fund planned operating and capital expense requirements into 2021. With the launch of a second global Phase 3 trial for efgartigimod, the execution of the development plan for cusatuzumab, the build-out of the commercial organization, and the expansion of the Company’s ambition level within its growing business plan, argenx expects operating and capital expense requirements to continue to increase year-over-year.

"The past quarter was highlighted by impressive data from our ongoing Phase 2 trial of tipifarnib in peripheral T-cell lymphoma (PTCL)," said Troy Wilson, Ph.D., J.D., President and Chief Executive Officer of Kura Oncology. "These data support the potential to register tipifarnib in both the angioimmunoblastic T-cell lymphoma (AITL) and PTCL not otherwise specified (PTCL-NOS) populations. In addition, we took further steps toward broadening the potential of farnesyl transferase inhibition to treat other CXCL12-driven indications of high unmet need, including diffuse large B-cell lymphoma (DLBCL), cutaneous T-cell lymphoma (CTCL), acute myeloid leukemia (AML) and pancreatic cancer. These advancements, along with the continued execution of our registration-directed study in HRAS mutant head and squamous cell carcinomas (HNSCC), are important steps toward establishing tipifarnib as a first-in-class farnesyl transferase inhibitor for patients with certain genetically defined cancers."

"As we look toward the second half of this year and early next year, we anticipate a number of milestones across our pipeline programs," continued Dr. Wilson, "including an update from our ongoing Phase 2 trial of tipifarnib in HRAS mutant HNSCC and other squamous cell carcinomas (SCCs), additional Phase 2 data in AITL, completion of the dose-escalation portion of the Phase 1 trial of our ERK inhibitor, KO-947, and initiation of the Phase 1 trial of our menin-MLL inhibitor, KO-539. With our successful public offering in June, we have greater resources and flexibility to continue to create value across our pipeline."

Recent Highlights

Registration-directed trial of tipifarnib in HRAS mutant HNSCC – Kura continues to execute on its initial registration-directed trial of tipifarnib in HRAS mutant HNSCC. The clinical trial has two cohorts: A non-interventional screening and outcomes cohort (SEQ-HN) and a treatment cohort (AIM-HN). AIM-HN is designed to enroll at least 59 evaluable patients with HRAS mutant HNSCC who have received prior platinum-based therapy. AIM-HN initiated in November 2018 and is expected to take approximately two years to fully enroll.

Positive Phase 2 trial of tipifarnib in AITL and CXCL12-driven PTCL – In June 2019, Kura reported positive data from its ongoing Phase 2 trial of tipifarnib in patients with relapsed or refractory PTCL, including clinical proof-of-concept in the trial’s two expansion cohorts: 1) patients with AITL, an aggressive form of T-cell lymphoma often characterized by high levels of CXCL12 expression, and 2) patients with PTCL who lack a single nucleotide variation in the 3’-untranslated region of the CXCL12 gene. The Company believes these data could support the potential registration of tipifarnib in both the AITL and PTCL-NOS patient populations and intends to seek regulatory feedback on next steps for this program. In addition, Kura plans to continue enrolling AITL patients in the trial and expects to provide additional data from this cohort at a medical meeting later this year.

Expanded patent protection for tipifarnib in the U.S. and Europe – The U.S. Patent and Trademark Office recently issued two new patents further protecting tipifarnib, including a method of treating patients with HRAS mutant HNSCC with any farnesyl transferase inhibitor and a method of treating patients with HRAS mutant non-small cell lung carcinoma with tipifarnib. In addition, the European Patent Office granted a patent directed to the use of tipifarnib as a method of treating patients with HRAS mutant HNSCC. The new patents have an expiration date of August 2036, excluding any possible patent term extension.

Dose escalation in Phase 1 trial of KO-947 advancing – Kura continues to evaluate dosing regimens for KO-947, its potent and selective small molecule inhibitor of ERK, in an ongoing Phase 1 trial, with a goal of reaching a recommended Phase 2 dose or maximum tolerated dose. The Company expects to complete the dose-escalation portion of the trial by the end of 2019.

Orphan Drug Designation to KO-539 for treatment of AML – Last week, the U.S. Food and Drug Administration (FDA) granted Orphan Drug Designation to KO-539, Kura’s menin-MLL inhibitor for the treatment of AML. The FDA cleared the investigational new drug application for KO-539 in March 2019, and the Company is in the final stages of study startup for a Phase 1 clinical trial of KO-539 in relapsed or refractory AML.

Successful public offering strengthens cash position – In June 2019, Kura completed a public offering in which the Company sold an aggregate of 6,785,000 shares of common stock at a price of $17.00 per share. Net proceeds from the public offering, after deducting underwriting discounts, commissions and offering expenses, were approximately $108.1 million.
Financial Results

Research and development expenses for the second quarter of 2019 were $11.4 million, compared to $11.5 million for the second quarter of 2018.

General and administrative expenses for the second quarter of 2019 were $4.5 million, compared to $3.8 million for the second quarter of 2018.

Net loss for the second quarter of 2019 was $14.9 million, or $0.38 per share, compared to a net loss of $14.7 million, or $0.45 per share, for the second quarter of 2018.

Cash, cash equivalents and short-term investments totaled $261.4 million as of June 30, 2019, which includes net proceeds of approximately $108.1 million from a public offering completed in June 2019, compared with $179.0 million as of December 31, 2018.

Management expects that current cash, cash equivalents and short-term investments will be sufficient to fund current operations into the second half of 2021.
Upcoming Milestones

Initiation of the Phase 1 trial of KO-539 in relapsed or refractory AML in the second half of 2019

Additional data from the ongoing Phase 2 trial of tipifarnib in HRAS mutant HNSCC and other SCCs in the fourth quarter of 2019

Additional data from the AITL expansion cohort in the ongoing Phase 2 trial of tipifarnib in the fourth quarter of 2019

Completion of the dose-escalation portion of the Phase 1 trial of KO-947 by the end of 2019

Second Quarter 2019 Financial Results:

Cash Position: As of June 30, 2019, cash, cash equivalents and investments were $667.3 million, as compared to $494.0 million as of December 31, 2018. This increase reflects net proceeds of approximately $327.4 million from the company’s follow-on underwritten public offering of common stock, which closed in April 2019, partially offset by cash used in operations.
Collaboration Revenues: Collaboration revenues were $5.1 million for the second quarter of 2019, as compared to $41.4 million for the second quarter of 2018. This decrease was primarily due to $40.0 million in revenue recognized under the CStone collaboration in the second quarter of 2018 upon execution of the collaboration agreement. During the second quarter of 2019, the company achieved and recognized a $4.0 million development and regulatory milestone payment under the CStone collaboration.
R&D Expenses: Research and development expenses were $87.1 million for the second quarter of 2019, as compared to $58.6 million for the second quarter of 2018. This increase was primarily due to increased clinical and manufacturing expenses driven by the company’s lead programs and increased personnel expenses. Research and development expenses included $7.5 million in stock-based compensation expenses for the second quarter of 2019.
G&A Expenses: General and administrative expenses were $21.9 million for the second quarter of 2019, as compared to $12.3 million for the second quarter of 2018. This increase was primarily due to increased personnel expenses and increased professional fees for commercial-readiness and other activities. General and administrative expenses included $6.2 million in stock-based compensation expenses for the second quarter of 2019.
Net Loss: Net loss was $99.7 million for the second quarter of 2019, or a net loss per share of $2.04, as compared to a net loss of $27.0 million for the second quarter of 2018, or a net loss per share of $0.62.
Financial Guidance:

Based on its current plans, Blueprint Medicines expects that its existing cash, cash equivalents and investments, excluding any potential option fees and milestone payments under its existing collaborations with Roche and CStone Pharmaceuticals, will be sufficient to enable it to fund its operating expenses and capital expenditure requirements into the middle of 2021.
