"We are excited to have dosed the first patient in our Phase 1 trial of PBCAR19B, a next-generation, CD19-targeted candidate incorporating our immune evading stealth cell technology. This is our fourth CAR T program in the clinic, demonstrating the modularity of ARCUS for allogeneic CAR T therapies," said Alan List, M.D., Chief Medical Officer of Precision BioSciences. "Moreover, we believe that our ARCUS-edited stealth cell technology holds the potential to safely improve the persistence of allogeneic CAR T cells without the need for prolonged immunosuppression, which may ultimately lead to deeper and more durable responses for patients."

The Phase 1 study will be a non-randomized, open-label, single-dose, dose-escalation and dose-expansion study designed to evaluate the safety and clinical activity of PBCAR19B at flat dose levels beginning at 2.7 × 108 with the ability to dose up to 8.1 × 108 CAR T cells per patient, following standard lymphodepletion1 in patients with R/R NHL. The first dose level of PBCAR19B is comparable to dose level 3 of the PBCAR0191 CAR T. The primary objective of the study is to identify the maximum tolerated dose and any dose-limiting toxicities. Clinical trial material for this study is generated at the Company’s in-house Manufacturing Center for Advanced Therapeutics (MCAT) in Durham, North Carolina.

About PBCAR19B (Clinical Trials Study Identifier: NCT04649112)
PBCAR19B is a next-generation, immune evading stealth cell candidate for patients with CD19-positive malignancies such as R/R NHL. PBCAR19B is designed to improve the expansion and persistence of allogeneic CAR T cells following infusion by reducing rejection by T cells and NK cells. In addition to the CAR gene, the PBCAR19B stealth cell vector carries a short hairpin RNA that suppresses expression of beta-2 microglobulin, a component of Class I Major Histocompatibility Complex (MHC) molecules found on the cell surface. Reducing or knocking-down Class I MHC expression on allogeneic CAR T cells has been shown to reduce CAR T cell killing by cytotoxic T cells. The PBCAR19B vector also carries an HLA-E gene intended to reduce rejection of CAR T cells by NK cells that can be stimulated as a result of reduced MHC molecule expression on the cell surface.

About Precision’s Allogeneic CAR T Platform
Precision is advancing a pipeline of cell-phenotype optimized allogeneic CAR T therapies, leveraging fully scaled, proprietary manufacturing processes. The platform is designed to maximize the number of patients who can potentially benefit from CAR T therapy. Precision carefully selects high-quality T cells derived from healthy donors as starting material, then uses its ARCUS genome editing technology to modify the cells via a single-step engineering process. By inserting the CAR gene at the T cell receptor (TCR) locus, this process knocks in the CAR while knocking out the TCR, creating a consistent product that can be reliably and rapidly manufactured and is designed to prevent graft-versus-host disease. Precision optimizes its CAR T therapy candidates for immune cell expansion in the body by maintaining a high proportion of naïve and central memory CAR T cells throughout the manufacturing process and in the final product.

Entry into a Material Definitive Agreement

On June 30, 2021, NGM Biopharmaceuticals, Inc. (the "Company") and Merck Sharp & Dohme Corp. ("Merck") reported that it entered into an Amended and Restated Research Collaboration, Product Development and License Agreement (the "Amended Agreement") that amends and restates their existing Research Collaboration, Product Development and License Agreement dated February 18, 2015, as previously amended (the "Original Agreement") (Filing, 8-K, NGM Biopharmaceuticals, JUN 30, 2021, View Source [SID1234584535]). The Original Agreement covered the discovery, development and commercialization of novel therapies across a range of therapeutic areas, including a broad, multi-year drug discovery and early development program financially supported by Merck, but scientifically directed by the Company with input from Merck. The Original Agreement contemplated an initial five-year research phase, and Merck was granted the unilateral right to extend the research phase of the collaboration for two additional two-year terms. In March 2019, Merck exercised its first option to extend the research phase of the collaboration for two additional years through March 16, 2022. Under the terms of the Amended Agreement, Merck and the Company agreed to extend the research phase of the collaboration generally until March 31, 2024 with a narrower scope than contemplated in the Original Agreement, which scope is focused on therapeutic areas of particular interest to Merck and is described in more detail below (the "Continuing Collaboration"). Accordingly, under the Amended Agreement, the Company now has the sole right, in its sole discretion, to independently research, develop and commercialize the product candidates known as NGM707, NGM120 and NGM438 and all other product candidates that the Company researched or developed under the Original Agreement that are not included within the scope of the Continuing Collaboration (collectively, the "NGM Product Candidates"). Product candidates that remain within the scope of the Continuing Collaboration under the Amended Agreement are referred to herein as the "Continuing Product Candidates." The parties’ rights and obligations with respect to MK-3655 and related FGFR1c/KLB agonists for which Merck exercised its option in November 2018 remain the same under the Amended Agreement as under the Original Agreement. Merck remains a significant stockholder of the Company.

Under the terms of the Amended Agreement, the Continuing Collaboration will focus on the identification, research and development of product candidates directed to targets in the fields of ophthalmology and cardiovascular or metabolic ("CVM") disease, and will also include laboratory testing and other activities on molecules that are directed to one of up to two undisclosed targets outside of the fields of ophthalmology and CVM disease (each, a "Lab program"). As it did under the Original Agreement, Merck has an option to take an exclusive, worldwide license for each Continuing Product Candidate that is identified, researched and developed under the Amended Agreement and reaches the specified option exercise point, as well as to all other related compounds that are directed to the same target and that result in the same effect on such target (each such option, a "Merck Option" and each such Continuing Product Candidate and its related compounds, a "program"). In addition, under the terms of the Amended Agreement, new CVM-related programs to which Merck would have such an option may be added to the Continuing Collaboration if recommended by the Company and selected by Merck. Merck has a one-time right to exercise its option, during the research phase or a tail period following such research phase, as applicable, for any Continuing Product Candidate on a program-by-program basis when the Company or Merck achieves the specified option exercise point. The option exercise point for candidates under the Original Agreement was the completion of a human proof-of-concept trial. This generally continues to be the option exercise point under the Amended Agreement for Continuing Product Candidates that are directed to ophthalmology targets, including NGM621 and its related compounds and all of the compounds from two other ophthalmology programs directed against undisclosed ophthalmology targets and their related compounds (collectively, including NGM621 and its related compounds, the "Continuing Ophthalmology Product Candidates"). Upon the completion of the CATALINA clinical trial, a human proof-of-concept trial that the Company is currently conducting on NGM621, Merck will have an additional one-time option to obtain an exclusive, worldwide license to all of the Continuing Ophthalmology Product Candidates. If Merck does not exercise this one-time option for all Continuing Ophthalmology Product Candidates (the "Bundle Option"), it may nevertheless exercise its regular option with respect to NGM621 and its related compounds at such time, and it may also exercise its regular options for the Continuing Ophthalmology Product Candidates from each of the other two programs if a Continuing Ophthalmology Product Candidate from such program completes a human proof-of-concept trial. Unlike the Original Agreement, the option exercise point for a product candidate from the CVM-related programs or the Lab program will be the designation by Merck of such candidate as a research program development candidate that Merck intends to progress into preclinical development.

The Company is primarily responsible under the Amended Agreement for all research and development for the ophthalmology programs prior to the relevant option exercise point and for the CVM-related programs prior to the expiration of the research phase for the CVM-related programs as described below. For the Lab program, the Company will be solely responsible for conducting or overseeing certain pre-specified research that is expected to be completed in early 2022, at which time Merck will decide whether to take sole responsibility for all subsequent research on compounds resulting from the Lab program prior to the option exercise point or to grant the Company the sole right, in its sole discretion, to independently research, develop and commercialize such Lab program compounds. As was the case under the Original Agreement, if Merck exercises a Merck Option and obtains the relevant exclusive, worldwide license for a Continuing Product Candidate and its related compounds, Merck will pay an option exercise fee to the Company and will be responsible, at its own cost, for any further development and commercialization activities for compounds within that licensed program. In such case, the Company will have the option to receive milestones and royalty payments or participate in the adjusted net sales in exchange for co-funding a share of the development costs and allowable expenses for any compound within that licensed program and an option to co-detail any such compound in the United States. Except for the Bundle Option, the amount of the option exercise fees for Continuing Ophthalmology Product Candidates upon completion of a human proof-of-concept trial remains the same as under the Original Agreement. If Merck exercises the Bundle Option, it will pay the Company either $40.0 million or $45.0 million as the option exercise fee, depending upon the stage of development of one of the two earlier stage ophthalmology programs that is included in the Bundle Option. Under the Amended Agreement, if Merck exercises the Merck Option for a candidate from a CVM-related program or the Lab program, Merck will pay the Company a $6.0 million option exercise fee and an additional $10.0 million milestone payment if such candidate or one of its related compounds subsequently completes a human proof-of-concept trial.

Merck remains committed under the Amended Agreement to provide up to $86.0 million in research funding for the four calendar quarters ending March 31, 2022, which includes the remaining $16.0 million of the up to $20.0 million in additional payments Merck agreed to pay as part of exercising its first option to extend the research phase of the collaboration under the Original Agreement for two years through March 16, 2022. The Company is obligated to use commercially reasonable efforts to expend $35.0 million of such funding during such time frame on the ophthalmology- and CVM-related programs, as well as the Lab program. The Company is permitted to use the remaining research funding provided by Merck during such time frame to advance the NGM Product Candidates, for which Merck no longer has option rights under the Amended Agreement. During the remaining two years of the research phase after March 2022, Merck will provide up to a total of $20.0 million in research funding for the ophthalmology- and CVM-related programs and Merck will also fund the research and development costs related to NGM621, including the Company’s CATALINA clinical trial, subject to certain limitations. After March 2022, the Company will use its own funding to complete the work needed to be ready to submit an investigational new drug application, or IND, for a specific product candidate included in one of the two earlier stage ophthalmology programs and it will use commercially reasonable efforts to complete such work by March 31, 2023. If Merck exercises its regular option for NGM621 or the Bundle Option for all of the Continuing Ophthalmology Product Candidates upon completion of the CATALINA clinical trial and pays the applicable option exercise fee to the Company, then the Company will be obligated to reinvest $5.0 million or $15.0 million, respectively, of such option fee to fund research on the ophthalmology- and CVM-related programs.

The research phase for the ophthalmology-related programs will end no later than March 31, 2024. The research phase for the CVM-related programs will continue until March 31, 2024, unless the parties mutually agree to extend the research phase to March 31, 2026, in which case Merck will provide up to a total of $20 million in research funding during those additional two years. The research phase for the Lab program will end no later than March 31, 2022.

As it did under the Original Agreement, Merck has the right under the Amended Agreement to review the then-ongoing research programs in the three-month period before the end of applicable research phase and to elect to designate one or more programs for which research and development would continue to be conducted, until the applicable option exercise point is reached, for up to three years after the end of such research phase, with the possibility of extension if ophthalmology clinical studies are then ongoing or if Merck determines to continue progressing a CVM-related program or Lab program toward the nomination of a research program development candidate (the "Tail Period"). The principal Tail Period-related changes in the Amended Agreement are that the Tail

Period, if any, for the ophthalmology-related programs would be separate from the Tail Period, if any, for the CVM-related programs and the Lab program and that Merck would be primarily responsible for performing all research and development activities, itself or through third party contractors, during the Tail Period, if any, for the CVM-related programs and the Lab program.

Similar to the Original Agreement, during the research phase and any applicable Tail Period of the Continuing Collaboration, the Company may not directly or indirectly research, develop, manufacture or commercialize, outside of the Continuing Collaboration, any product with specified activity against any target that is being researched or developed under the Continuing Collaboration and, if Merck exercises its option for a program, the Company may not directly or indirectly research, develop, manufacture or commercialize any product with specified activity against the target that is the subject of that program for so long as Merck’s license to it remains in effect. In addition, under the Amended Agreement, the Company is prohibited from, direct or indirectly, researching, developing or commercializing any product for the treatment of heart failure with preserved ejection fraction (HFpEF) during the research phase for the CVM-related programs.

Upon the signing of the Amended Agreement, Merck’s options to the NGM Product Candidates were extinguished and the Company gained the right to research, develop and commercialize all NGM Product Candidates, in its sole discretion and at its expense, without any obligations to Merck other than to pay royalties to Merck at low single digit rates on the sales of any NGM Product Candidates that receive regulatory approval and, if the Company decides during a certain time period to engage in a formal partnering process for an NGM Product Candidate or negotiations regarding a license or asset acquisition for an NGM Product Candidate, to notify Merck, provide Merck with certain information and engage in good faith, non-exclusive negotiations with respect to such NGM Product Candidate with Merck at Merck’s request.

The foregoing description of the Amended Agreement does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Amended Agreement, a redacted copy of which will be filed as an exhibit to the Company’s quarterly report on Form 10-Q for the quarter ended June 30, 2021. Refer to the Company’s annual report on Form 10-K, filed with the Securities and Exchange Commission ("SEC") on March 15, 2021, for additional information regarding the Company’s collaboration with Merck.

XNK Therapeutics Reports First Patient Included in Phase II Study in Multiple Myeloma

On July 1, 2021 XNK Therapeutics AB ("XNK") reported that the first patient has been included in a Phase II clinical study to treat patients with Multiple myeloma using XNK’s leading autologous natural killer (NK) cell-based candidate drug in combination with Sanofi’s anti-CD38 antibody Sarclisa (Isatuximab).

"Having the first patient included in this clinical study is a key step in XNK’s development", said Johan Liwing, CEO of XNK Therapeutics. "While our leading drug candidate is now entering into Phase II, we are in parallel dedicated to progressing our clinical development plan into other indications building on a Phase I/II first-in-human study".

The present investigator-initiated, open, randomized, controlled, Phase II study ISA-HC-NK (EudraCT: 2020-000994-26) compares XNK’s leading candidate drug combined with Sanofi’s anti-CD38 antibody Isatuximab with Isatuximab alone as a consolidation treatment following autologous stem cell transplantation in patients with newly diagnosed Multiple myeloma. The clinical study takes place at the Karolinska University Hospital at its Huddinge site, and encompasses at total of 60 patients with 30 patients in each treatment arm.

"Combining NK cells that mediate antibody dependent cellular cytotoxicity (ADCC) with targeted antibodies is an appealing concept. The idea envisaged is a synergetic effect with possible reduced toxicity, helping the Multiple myeloma patients maintaining a disease-free stage. This study is unique as it is the first investigator-initiated study randomizing patients to an NK cell-based therapy", said Hareth Nahi, Associate Professor at Karolinska Institutet and Principal Investigator for the study.

XNK Therapeutics and Sanofi are both collaborative industrial partners within NextGenNK, a recently established Competence Center for the development of next-generation NK cell-based cancer immunotherapies coordinated by Karolinska Institutet and supported by Sweden’s Innovation Agency (Vinnova).

Taiho Smile Support is an initiative to support organizations and individuals seeking to solve various social issues in the field of oncology that cannot be solved by drugs alone. Taiho Pharmaceutical will be calling for organizations and individuals who plan to use crowdfunding to raise funds to address these social issues. Selected organizations and individuals will conduct a crowdfunding campaign and, if they reach their funding target,1 they will receive matching funds equal to the target they have raised from Taiho Pharmaceutical in the form of a donation.

If the crowdfunding target is achieved
For example, suppose the cost for an entire project is 1 million yen. If the project is selected, then the crowdfunding target will be set at 500,000 yen (50% of the necessary cost). If the organizer succeeds in raising the funding target, Taiho Pharmaceutical will then provide matching funds of 500,000 yen (the other 50%) to support the project.

Through this program, Taiho Pharmaceutical aims to support the dreams of organizations and individuals who are working to address challenges in the field of oncology. In partnership with these organizations, individuals, and all of the people who support them via crowdfunding, Taiho Pharmaceutical seeks to create a world where the precious moments of everyday life keep flowing for cancer patients and their families, "Today and Every Day."

1 The crowdfunding target is to be 50% of all funds needed to realize the project. If the target is met, Taiho Pharmaceutical will provide the remaining 50%. Thus, the success of the crowdfunding campaign will determine whether or not Taiho Pharmaceutical will provide support.

Round One of Taiho Smile Support
Theme
A project that will use crowdfunding to take on the challenge of solving various issues (physical, mental, social, or economic) surrounding cancer, under the theme of "Addressing Issues in the Field of Oncology."
(Examples: Activities to support cancer patients and their families; activities to raise awareness of cancer and spread education about cancer; or activities to convey the importance of early detection of cancer. The activities can take place in Japan, another country, or be international.)

The alliance aims to foster collaborations with pharmaceutical companies for the development of drug treatments for cancer and promote early clinical adoption of ultra-sensitive liquid biopsy companion diagnostics. QIAGEN and Sysmex have a longstanding partnership, which, for example, provides the ipsogen JAK2 blood-cancer test in Japan. Cancer companion-diagnostics products will be launched by QIAGEN and Sysmex in various regions of the world.

Genetic analysis of tumors makes it possible to identify the genes responsible for the development and spread of a tumor and to target treatment accordingly. But the traditional analysis of solid tumors is constrained by their heterogeneity – varying concentrations of cancer cells, for example – and by sample availability. Liquid biopsy addresses these challenges and, in combination with sensitive NGS, allows the evaluation of patients at different points of their cancer treatment. It enables doctors to spot new anomalies and adjust treatments to make them more precise, and to develop novel targeted therapies.

"Combining QIAGEN’s global reach with Sysmex’s NGS capabilities is an important milestone in advancing the use of NGS technologies in clinical decision-making and is a testament to our shared vision of using this powerful technology to improve outcomes for patients worldwide," said Jean-Pascal Viola, Senior Vice President, Head of the Molecular Diagnostics Business Area and Corporate Business Development at QIAGEN. "This alliance will add strong NGS capabilities to our regulatory and clinical expertise and commercialization, and help our partners in the pharmaceuticals industry by expanding our strong position and product offering in companion diagnostics. We look forward to this alliance creating significant benefits for our pharma partners – and ultimately for treating patients."

"The alliance with QIAGEN promises Sysmex a great application for Sysmex’s Plasma-Safe-SeqS technology, which can detect gene mutations of cancer in blood with ultra-high sensitivity. We believe that QIAGEN is the best for Sysmex to expand this globally," said Hiroshi Kanda, Member of the Managing Board and Senior Executive Officer, Head of Corporate Business Development at Sysmex.

QIAGEN is a pioneer in precision medicine. It is the global leader in collaborating with pharmaceuticals and biotechnology companies to co-develop companion diagnostics that detect genetic abnormalities and guide clinical decision-making. QIAGEN has an unmatched breadth and depth of technologies – from NGS to polymerase chain reaction (PCR) – for companion-diagnostics development. QIAGEN’s portfolio includes ten PCR-based companion-diagnostics products that are approved by the FDA. They include therascreen EGFR for non-small cell lung cancer, therascreen KRAS for colorectal cancer and NSCL (including the G12C mutation), therascreen FGFR for urothelial cancer, therascreen PIK3CA for breast cancer based on tissue or plasma samples, and the therascreen BRAF kit for colorectal cancer.

QIAGEN has master collaboration agreements with more than 25 companies to develop and commercialize companion diagnostics for drugs in development – a pipeline of potential products to advance precision medicine and benefit patients. QIAGEN has partnered with Illumina to broaden the use of NGS-based companion and other in-vitro diagnostics (IVD) kits in patient management.
