(c)

Guaranteed minimum royalties: Licensee shall pay to MSK minimum annual royalties of [ * ] on the [ * ] anniversary of the Effective Date and on each subsequent anniversary until [ * ]; provided that for as long as Licensee [ * ], such obligation to pay such minimum annual royalties shall not be applicable.

(d)

Milestones:

Milestone payments as follows:

The following milestone payments shall be due for a Licensed Product for the first indication only.

Payment Terms: Payments owed under this Agreement shall be payable [ * ] after they are due (except as provided below for royalties), paid in United States dollars in New York, NY, or at such other place as MSK may reasonably designate consistent with the laws and regulations controlling in any foreign country and provided that such designation does not impose additional costs, fees or payment obligations on Licensee. Royalty payments are due [ * ] after the end of the Contract Quarter-Year during which such royalty obligations accrued. If any currency conversion shall be required in connection with the payment of royalties hereunder, such conversion shall be made by using the exchange rate prevailing at the ▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇ Bank on the last business day of the Contract Quarter-Year reporting period to which such royalty payments relate.

Additionally, in the event of a dispute concerning the determination of royalties or milestones, or whether royalties or milestones are owed, that arises from disagreement over whether a T-cell product sold by or on behalf of Licensee qualifies as a Licensed Product, the Parties shall agree on a reasonable procedure for the provision of necessary technical information in confidence to a qualified representative of MSK to attempt to resolve such dispute.

ARTICLE 7 – PATENT PROSECUTION; THE LICENSED PATENTS

7.1

Promptly after the Effective Date, MSK and Licensee shall form an “IP Committee,” [ * ], each having reasonable experience and expertise in managing intellectual property matters (which may be the representatives in the “IP Committee” formed under the Option Agreement). The IP Committee shall be responsible for discussing and establishing the patent prosecution strategy for the Licensed Patent Rights including any additional patent applications covering any potentially patentable inventions within the Licensed Tangible Materials and/or Licensed Know-How, and for reviewing and managing the prosecution of any Licensed Patent Rights including such additional patent applications that are determined by the IP Committee to be filed covering any such inventions. Promptly after the Effective Date, Licensee shall add to Exhibit C of this Agreement all Licensed Patent Rights existing as of the Effective Date hereof, and each additional Licensed Patent Right filed by MSK hereunder (including filed as continuing applications based on the further prosecution of such Licensed Patent Rights) shall be listed by the Parties on Exhibit C of this Agreement, and the Parties shall update such Exhibit C list to reflect all additional Licensed Patent Rights filed or issued, and updates in the prosecution thereof.

7.2

MSK shall undertake, at Licensee’s expense (as provided below) and using Commercially Reasonable Efforts, and as directed by the IP Committee, to prosecute and maintain the Licensed Patent Rights owned solely by MSK in the United States and in such countries as are determined by MSK upon consultation with Licensee, using counsel of MSK’s choice reasonably acceptable to Licensee. Licensee shall reimburse MSK for the actual Patent Expenses incurred in such prosecution and maintenance of the Licensed Patent Rights, pursuant to invoices showing the actual Patent Expenses incurred which shall include copies of the documentation demonstrating the out-of-pocket expenses. If Licensee advises that it does not wish to pursue or maintain a patent or application, MSK may continue to prosecute and maintain it at its own expense, and such patent or application shall be excluded from the license granted hereunder if MSK does so.

7.3

MSK shall keep Licensee reasonably informed of the progress of its prosecution efforts, by providing Licensee with copies of all material patent prosecution documentation so that Licensee may be informed and advise MSK on the continuing prosecution, and MSK agrees to consider in good faith all such reasonable comments. Licensee shall keep this documentation confidential.

7.4

Licensee shall, at Licensee’s expense and using Commercially Reasonable Efforts, and as directed by the IP Committee, to prosecute and maintain the Licensed Patent Rights owned jointly by Licensee and MSK, in the United States and in such countries as are determined by Licensee upon consultation with the IP Committee, using counsel of Licensee’s choice. If Licensee advises that it does not wish to pursue or maintain a patent or application in such joint Licensed Patent Rights, MSK may continue to prosecute and maintain it at its own expense, and such patent or application shall be excluded from the license granted hereunder if MSK does so, provided that Licensee will retain its ownership interests therein. Licensee shall control, at its sole discretion, prosecution of any patents covering inventions owned solely by Licensee.

7.5

The Parties agree that they share a common legal interest in obtaining valid, enforceable patents and that Licensee, and MSK will maintain confidential all information received pursuant to this Article 7.

7.6

Licensee shall not challenge the validity or enforceability of any claim within the Licensed Patents Rights and shall cause its Affiliates to refrain from doing so. In addition to all other rights and remedies available to MSK for any breach of this provision by Licensee or its Affiliates, in the event that any such challenge is not successful then Licensee shall reimburse MSK for all costs and expenses, including but limited to attorneys fees, incurred by MSK as a result of defending against such challenge.

ARTICLE 8 – INFRINGEMENT

8.1

Monitoring. Licensee shall use commercially reasonable efforts to monitor third party infringement of the Licensed Patent Rights in the Field of Use. Licensee shall keep MSK timely informed of any activities by Licensee in regard hereto.

8.2

Actions. This Section sets forth each of the Party’s right of enforcement and defense in relation to the Licensed Patent Rights.

(a)

First Right. Licensee shall have the first right, but not the obligation, for the initiation, defense, and management of any adversarial legal proceeding relating to the Licensed Patent Rights in the Field of Use and Territory, including without limitation any declaratory judgment action, patent infringement action or opposition (collectively, “Patent Adversarial Actions”) during the Term, and will be responsible for all expenses related thereto. MSK shall provide Licensee with all reasonable assistance and cooperation in conducting and/or defending against any such Patent Adversarial Action, including joining in any such Patent Adversarial Action, at Licensee’s request and expense, provided that in any case Licensee shall at all times have the full control of conducting and/or defending such Patent Adversarial Action. For clarity, Licensee may delegate the foregoing rights to its Sublicensee, in the territory where such Sublicensee has sublicense rights hereunder.

(b)

Secondary Right. If Licensee determines, as to any particular third party activity that constitutes a material infringement of the Licensed Patent Rights or a declaratory judgment action involving the Licensed Patent Rights, that Licensee shall not exercise its rights to conduct a Patent Adversarial Action as to such activity, then Licensee shall provide MSK with written notice that Licensee declines such right as to such activity, and after receiving such notice, MSK shall have the secondary right to undertake such infringement action or defend against such challenge, provided that MSK shall keep Licensee fully informed of all its activities with respect thereto and shall not take any action, or omit to take any action or position, that causes or likely will cause a material adverse impact on Licensee or its Sublicensee or on the Licensed Patent Rights.

8.3

Cooperation; Settlement. To the extent that a Party conducts any legal proceedings in relation to the enforcement or defense of Licensed Patent Rights in the Field of Use and Territory as contemplated above, it shall keep the other Party reasonably informed of such proceedings. At such Party’s request, the other Party shall reasonably cooperate, at the expense of the requesting Party, in such proceedings. In any action conducted by MSK, Licensee will join as may be requested by MSK, and in any action conducted by Licensee, Licensee may affect joinder of MSK if MSK is an indispensible or necessary party under the applicable law. Notwithstanding anything in this Agreement to the contrary, no settlement, consent

judgment, or other voluntary final disposition of any action by Licensee that admits the invalidity or unenforceability of the Licensed Patent Rights may be entered into without the prior written consent of MSK.

8.4

Costs and Recoveries. All costs of any action by a Party to enforce, or to defend against a challenge to, the Licensed Patent Rights shall be borne by such Party, and such Party shall keep any sums recovered or obtained in connection therewith (whether as damages, reasonable royalties, license fees, or otherwise in judgment or settlement derived therefrom), except that in the case of actions commenced by Licensee, the excess of such sums over all such costs and expenses shall be treated as Net Sales subject to MSK’s rights under this Agreement to collect royalties thereon. For the avoidance of doubt, Licensee may not deduct, from Net Sales any portion of Licensee’s costs or expenses related to any investigation, enforcement, defense, judgment or settlement of any such actions, provided that if Licensee is the enforcing Party, it may deduct from Net Sales the costs and expenses of MSK, incurred in connection with MSK providing cooperation in such enforcement, that are reimbursed or paid by Licensee pursuant to Section 8.3.

8.5

Third Party Patents. In the event Licensee is sued for patent infringement or, threatened with such suit, it shall promptly notify MSK. In any such action, Licensee shall be fully responsible for all its costs, including expenses, judgments and settlements (but subject to Section 5.1(b)).

ARTICLE 9 – MANUFACTURE AND SUPPLY

9.1

[Intentionally omitted].

9.2

Manufacturing Transfer. Commencing on [ * ], MSK will conduct and complete a full manufacturing transfer to Licensee (and/or its designated contract manufacturing organization(s)) of all existing MSK technology and manufacturing know-how and methods and materials relating to Licensed Product manufacturing, such technology transfer to be conducted on a reasonable, diligent time frame so as to enable completion of the transfer promptly and on a timely basis (taking into account Licensee’s product development schedule and needs). In connection therewith, MSK agrees to make reasonably available its personnel to assist Licensee with transfer of manufacturing operations to a new facility, including assistance with understanding all the transferred technology and manufacturing information, at no FTE expense to the Licensee. For clarity, the assistance to be provided by MSK does not include transferring equipment, but does include full transfer of all manufacturing SOPs and the identity of the and source of the equipment used in MSK’s manufacturing of Licensed Products.

9.3

Licensed Product Supply. The terms of the Parties’ agreement governing MSK’s manufacture and supply of Licensed Products to Licensee of its (and its Affiliates’ and Sublicensees’) requirements for Licensed Products for use in clinical trials during development, are set forth in the Manufacturing Services Agreement entered into by the Parties concurrent with this Agreement (“Manufacturing Services Agreement”).

9.4

Library. The terms of the Parties’ agreement governing the maintenance, improvement and augmentation of the Library and Databases, and the transfer of the Library and Databases to Licensee and its designee(s), are set forth in the Manufacturing Services Agreement.

ARTICLE 10 – CONFIDENTIALITY

(b)

be disclosed only to those who have a need to know it in connection with the Agreement; and

(c)

be safeguarded with the same care normally afforded confidential information in the possession, custody or control of the party holding the Confidential Information but no less than reasonable;

(iv)

is subsequently received by the receiving Party from a third party without breaching any confidential obligation between the third party and the disclosing Party; or

(v)

was independently developed, as established by tangible evidence, by the receiving Party without reference to the Confidential Information of the disclosing Party.

Notwithstanding the foregoing, a receiving Party may disclose particular Confidential Information of the disclosing Party to the extent such information is required to be

disclosed in order to comply with court orders, statutes or regulations, provided that prior to any such disclosure, to the extent reasonably practicable, the Party from whom disclosure is sought shall promptly notify the other Party and shall afford such other party the opportunity to challenge or otherwise lawfully seek limits upon such disclosure of Confidential Information, and that the disclosing Party only discloses such Confidential Information as is legally required to be disclosed, taking into account any protective or other order limiting or quashing the disclosure obligation.

Further, notwithstanding the foregoing, Licensee (or its Affiliate or Sublicensee) may disclose Confidential Information of MSK: (a) as reasonably needed to prosecute or enforce Licensed Patent Rights; (b) to regulatory authorities as reasonably needed to develop and/or obtain or maintain regulatory approvals of Licensed Products; (c) in confidence to its Affiliates and Sublicensees as reasonably needed to research, develop and/or commercialize Licensed Products; (d) in confidence to prospective sublicensee, strategic partners, merger partners or acquirers, and their respective professional advisors, in connection with evaluation and/or negotiation of possible sublicense, corporate partnering, merger, asset purchase or other similar transactions; (e) as required in order to comply with applicable law or regulations, including securities laws and securities exchange requirements; (f) in confidence to its existing investors and professional advisors and to potential investors and their professional advisors; and (g) as reasonably needed to conduct or defend any litigation relating to this Agreement, the Licensed Products or Licensee’s rights hereunder.

Licensee shall indemnify, defend and hold harmless MSK and its trustees, directors, officers, medical and professional staff, employees, students, and agents and their respective successors, heirs, and assigns (each an “Institution Indemnitee”), against all costs, liabilities and expenses (including legal expenses and reasonable attorney’s fees) (“Costs”) resulting directly from a third party claim, proceeding, or demand against an Institution Indemnitee (a “Claim”) to the extent arising directly out of: (a) the death of or injury to any person or persons, or any damage to property, resulting from the development or commercialization of a Licensed Product by Licensee or its Affiliate or Sublicensee under this Agreement; (b) production, manufacture, sale, use, lease, consumption, or advertisement of Licensed Products hereunder by Licensee or its Affiliate or Sublicensee, or (c) the breach by Licensee of any of its representations, warranties or obligations under this Agreement or any Ancillary Agreement, provided however, that Licensee will not be obligated to indemnify, defend and hold harmless any Institution Indemnitee against any Cost or Claim to the extent it arises out of, results from, or is increased by (w) MSK’s or an Institution Indemnitee’s breach of its representations or warranties under this Agreement or the Manufacturing Services Agreement, (x) MSK’s or an Institution Indemnitee’s willful misconduct or gross negligence, or (y) MSK’s supplying to Licensee a Licensed Product manufactured by (or on behalf of) MSK that does not conform to the specifications therefor or to FDA manufacturing requirements or guidance, or has otherwise not been manufactured

in accordance with the requirements of the Manufacturing Services Agreement), or (z) any clinical trials conducted by, or other use of any Licensed Product by, MSK or its Affiliate at any time, other than under authority of Licensee.

11.2

The Institution Indemnitee will promptly give notice to Licensee of any covered Claims for which it seeks indemnification hereunder, and Licensee will have the right to defend the same, including selection of counsel reasonably acceptable to MSK, and to control of all the proceedings; provided that Licensee will not, without the written consent of the Institution Indemnitee, settle such Claim or consent to the entry of any judgment to the extent that such settlement or judgment: (i) does not release the Institution Indemnitee from all liability with respect to such third party Claim, or (ii) likely will materially adversely affect the Institution Indemnitee or under which the Institution Indemnitee would incur any material obligation or liability. MSK and each applicable Institution Indemnitee agrees to cooperate and provide all reasonable assistance to the defense of any such Claim, at Licensee’s expense. MSK at all times reserves the right to select and retain counsel of its own at its own expense to defend MSK’s interests, provided that MSK shall be responsible for any Costs incurred or resulting from any actions of such counsel that are contrary to Licensee’s control or conduct of the defense.

ARTICLE 13 – COMPLIANCE WITH LAW

13.1

It is understood that MSK is subject to United States laws and regulations controlling the export of technical data, computer software, laboratory prototypes and other commodities (including the Arms Export Control Act, as amended and the Export Administration Act of 1979), and that its obligations hereunder are contingent on compliance with applicable United States export laws and

ARTICLE 14 – NON-USE OF MSK’S NAME

Licensee shall not use the names of MKSCC, including Memorial Sloan Kettering Cancer Center, Sloan Kettering Institute for Cancer Research, and Memorial Hospital for Cancer and Allied Diseases, nor any of their employees, nor any adaptation thereof, in any public announcements, publicity or advertising without prior written consent obtained from MSK in each case, except as otherwise expressly permitted in this Agreement. MSK agrees that Licensee may issue a press release regarding this Agreement in the form attached as Exhibit E. In acknowledgement that Licensee may need to use the name of MSK or the MSK investigators in furtherance of the Licensee’s efforts to obtain financing, in connection with strategic or licensing discussions, and in other legitimate business matters of the Licensee, MSK agrees that Licensee may disclose in confidence to such parties (and their professional advisors) the terms of this Agreement, and for any additional disclosures regarding MSK or MSK investigators that Licensee requests to make so such parties, MSK shall use good faith efforts to secure prior written consent for such use in a timely manner in line with its business practices following receipt of a written request for such use by Licensee. For clarity, Licensee may request MSK pre-approve documents which make use the name of MSK for use in non-public and/or confidential venues in furtherance of the Licensee’s efforts to obtain financing, negotiate licenses, and secure personnel: upon receipt of such written pre-approval, Licensee may use the name of MSK in such non-public and/or confidential venues without prior written consent in each case to the extent such use does not deviate significantly from the pre-approved documents. Notwithstanding the foregoing, Licensee may disclose in confidence that Licensee has the Agreement and license rights granted hereunder

from MSK, and the general terms of the Agreement. Further, Licensee shall be free to continue to publish or disclose specific information about MSK or this Agreement that MSK has previously consented, pursuant to the above, may be publicly disclosed by Licensee, but only in the form, manner, and extent of MSK’s prior approval.

ARTICLE 15 – PUBLICATION

Licensee recognizes and accepts that under MSK’s mission as an academic medical center, MSK and its investigators must have a meaningful right to publish without Licensee’s prior approval or editorial control, but subject to reasonable prior review and comment. Subject to the following, MSK reserves the right to publish the scientific findings from research and clinical trials (to the extent permitted by Licensee as provided below) related to Licensed Rights and Licensed Products. Prior to making any proposed publication (e.g., manuscript, abstract or other public disclosure), of data and results relating to the Licensed Tangible Materials and/or Licensed Know-How and/or Licensed Products, and/or that contains Confidential Information of Licensee or its Affiliates, MSK will submit the abstract or manuscript to Licensee and to the IP Committee at least [ * ] before public submission or disclosure thereof. The IP Committee shall immediately review such proposed publication or submission to determine if there are any impacts on potentially patentable inventions and shall inform the Parties of its determinations. Licensee shall have the right to review and comment upon the proposed public disclosure in order to protect such Confidential Information and the patentability of any inventions disclosed therein, and may request that certain results, data or information not be disclosed if such disclosure likely would negatively impact the development or commercialization of any Licensed Product, and MSK will reasonably consider all such requests. Further, upon Licensee’s request, public disclosure shall be delayed [ * ] to enable MSK to secure adequate intellectual property protection of any patentable or trade secret subject matter contained therein that would otherwise be negatively affected by the publication. For clarity, publication of clinical data from permitted clinical trials by MSK on Licensed Products shall be pursuant to the terms of the applicable clinical trial agreement, investigator sponsored trial agreement or other agreement with Licensee.

ARTICLE 16 – ASSIGNMENT

A Party may not assign or delegate its rights or obligations under this Agreement or any Ancillary Agreement, or transfer or assign this Agreement or any Ancillary Agreement, without the prior written consent of the other Party, such consent not to be unreasonably withheld, except that (a) Licensee shall have the right to assign any of its rights, delegate any of its obligations, or transfer this Agreement or any Ancillary Agreement without such consent (i) to its Affiliate or (ii) as part of a merger or acquisition, and (b) MSK may without consent of Licensee freely assign all or any portion of the payments due under this Agreement to a Third Party, provided that [ * ] and [ * ]

[ * ]. Any assignment by Licensee shall bind its assignee to all provisions of this Agreement (or the applicable Ancillary Agreement, as the case may be), including without limitation those concerning dispute resolution (choice of law, choice of forum, and consent to jurisdiction in New York). Any assignment, delegation or transfer by any party without the consent of the other party shall be void and of no effect. For clarity, nothing in the foregoing shall limit Licensee’s (or its Affiliate’s or Sublicensee’s) ability to grant sublicenses or to engage contractors to perform obligations on behalf of any such party.

ARTICLE 17 – TERMINATION

19.3

Severability. Except to the extent a provision is stated to be essential, or otherwise to the contrary, or such provision is material and essential to the main purpose and intent of the Agreement, the provisions of this Agreement are severable, and in the event that any provisions of this Agreement shall be determined to be invalid or

unenforceable under any controlling body of the law, such invalidity or unenforceability shall not in any way affect the validity or enforceability of the remaining provisions hereof, provided that the Parties will endeavor in good faith to agree on a replacement, valid provision, to add to this Agreement in the stead of such invalid provision, that comes closest to achieving the intent of the Parties in such provision.

19.4

Waiver. The failure of either party to assert a right hereunder or to insist upon compliance with any term or condition of this Agreement shall not constitute a waiver of that right or excuse a similar subsequent failure to perform any such term or condition by the other party.

19.5

Counterparts. This Agreement may be executed in any number of counterparts and each of such counterparts shall for all purposes be an original and all such counterparts shall together constitute but one and the same agreement.

19.6

Force Majeure. A Party shall not lose any rights hereunder or be liable to the other Party for damages or losses (except for payment obligations) on account of a delay or failure of performance by the such party to the extent such the delay or failure is occasioned or caused by war, strike, fire, Act of God, tornado, hurricane, earthquake, fire, flood, lockout, embargo, governmental acts or orders or restrictions (except if imposed due to or resulting from the party’s violation of law or regulations), failure of suppliers, or any other circumstance or reason where the delay or failure to perform is beyond the reasonable control of such Party (a “Force Majeure”), and provided that such failure is not caused by the gross negligence or intentional misconduct of the Party and the Party has exerted reasonable efforts to avoid or remedy the effects of such Force Majeure; However, if a Force Majeure event causes a material failure of performance by a Party for a period of more than six months, then the other Party may terminate this Agreement on written notice.

19.7

Entire Agreement. This Agreement, including its attachments and exhibits (which attachments and exhibits are incorporated herein by reference), constitutes the entire understanding among and between the parties with respect to the subject matter hereof, and supersedes all prior agreements and communications, whether written, oral or otherwise.

Atara Biotherapeutics Exercises Exclusive License to T-Cell

Technology from Memorial Sloan Kettering Cancer Center

Activated T-cell Technology Designed to Harness Immune System

to Fight Cancer and Infectious Disease

South San Francisco, Calif., June 15, 2015 – Atara Biotherapeutics, Inc. (Nasdaq: ATRA) today announced that it has exercised its exclusive option with Memorial Sloan Kettering Cancer Center (MSK) to license certain clinical stage, allogeneic T-cell therapies for the treatment of cancers and persistent viral infections. In connection with the exercise of the option, the Atara Bio license agreement with MSK grants Atara Bio exclusive worldwide rights to the following three allogeneic T-cell therapies:

•

T-cells activated against ▇▇▇▇▇▇▇ ▇▇▇▇ Virus, or EBV (Phase 2);

•

T-cells activated against Cytomegalovirus, or CMV (Phase 2); and

•

T-cells activated against Wilms Tumor 1, or WT1 (Phase 1)

These three programs share a common technology, under which third-party donor-derived whole blood is collected and enriched for T lymphocytes, or T-cells. The T-cells are then exposed to certain antigens, and the resulting activated T-cells are characterized and stored for future therapeutic use. Using a proprietary algorithm, patients are treated with a partially human leukocyte antigen, or HLA, matched cell line, providing an “off-the-shelf,” allogeneic, cellular therapeutic option for patients. These T-cell products are intended to work by targeting the abnormal cells expressing the applicable target antigen and killing them.

Atara Bio announced earlier this year that its collaborating investigator at MSK received breakthrough therapy designation from the U.S. Food and Drug Administration for its cytotoxic T lymphocytes (CTL) activated against ▇▇▇▇▇▇▇-▇▇▇▇ Virus (EBV-CTL) in the treatment of patients with rituximab-refractory, EBV-associated lymphoproliferative disease (EBV-LPD).

Clinical data have been presented as follows:

•

EBV-CTL in the treatment of patients with EBV-LPD after solid organ transplantation at the 2015 American Society of Clinical Oncology Annual Meeting.

•

EBV-CTL in the treatment of patients with EBV-LPD after allogeneic hematopoietic cell transplantation (HCT) at a Clinical Trial Plenary Session at American Association for Cancer Research Annual Meeting 2015

•

CMV-CTL in the treatment of patients with anti-viral resistant CMV after HCT including viremia only and CMV disease at the American Society of Hematology Annual Meeting 2014.

“Licensing these programs more than doubles the clinical stage programs active at Atara Bio and provides a potential platform technology that can be directed at other targets,” said ▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇▇, MD, Chief Executive Officer and President of Atara Bio. “Our T-cell programs use third party donor cells, and, if approved by regulatory authorities, will be available as “off-the-shelf” therapies for patients in need.”

▇▇▇▇▇▇▇ ▇’▇▇▇▇▇▇, MD, Chair of the Department of Pediatrics and Chief of the Pediatric Bone Marrow Transplant Service at MSK, notes that “We are delighted that Atara will continue to develop our existing T-cell technologies that have shown promising clinical benefit in patients. We also look forward to expanding the platform to treat patients with other types of cancer through our sponsored research efforts with Atara.” ▇▇. ▇’▇▇▇▇▇▇ will join Atara Bio’s Scientific Advisory Board.

In connection with the exercise of the option and entry into the exclusive license agreement, MSK received an upfront license fee and will be eligible to receive additional payments based on the achievement of certain development, regulatory and sales-related milestones, as well as royalty payments. Atara Bio and MSK have agreed to collaborate on further research to develop additional cellular therapies, which may include T-cell therapies targeted against other antigens and/or chimeric antigen receptor-modified T-cells, known as CAR-T.
