Conduct of the Study

2.1 Overview. The Parties wish to collaborate regarding the Study to be conducted under this Agreement. Each Party shall use commercially reasonable efforts to perform its obligations hereunder. Nothing in this Agreement shall (a) prohibit either Party from performing any additional studies relating to its own Compound, either individually or in combination with any other compound or product, in any therapeutic area or (b) create an exclusive relationship between the Parties with respect to either Compound. The Parties may agree to conduct subsequent clinical studies using the Combination, as described in Section 2.11.

2.2 Sponsor. Syndax shall be the Sponsor of the Study; in no event shall any member of the Roche Group be deemed a Sponsor of the Study. Syndax shall conduct, and use commercially reasonable efforts to cause all Project Participants to conduct, the Study in accordance with this Agreement, the Protocol and Applicable Law. Syndax shall be responsible for obtaining all approvals and clearances necessary to conduct the Study, including approvals from Regulatory Authorities and IRBs and customs clearances.

2.3 IND; Investigator’s Brochure. Syndax shall own and shall file the Collaboration IND. For the avoidance of doubt, the Collaboration IND will not be a combination IND. If a Regulatory Authority requests a separate combination IND for the Study, the Parties shall meet and agree on an approach to address such request. Each Party shall be responsible for (a) drafting, and updating as necessary for the Study, an investigator’s brochure for its Compound and (b) filing, as applicable, all necessary Regulatory Documentation to its existing IND for its Compound, including submitting to such IND any serious adverse event and adverse drug reaction cases emerging from the Study. Genentech shall provide to Syndax those portions of the investigator’s brochure (and any updates) for the Genentech Compound that pertain to safety information and are necessary to submit or amend the Collaboration IND or to conduct the Study.

2.4 Protocol. The Parties agreed to a summary of the Protocol prior to executing this Agreement, and a complete Protocol will be developed by Syndax and approved by the Joint Development Committee after the Effective Date. Any proposed amendments to the Protocol necessary to protect the safety of Subjects shall be promptly reported to Genentech in writing. Notwithstanding anything to the contrary in this Agreement, the prior written consent of Genentech is required for amendments to the Protocol that are (a) material amendments (other than relating solely to the Syndax Compound), including the maximum number of Subjects to be enrolled in the Study and (b) amendments (whether or not material) relating specifically to the Genentech Compound. Genentech shall provide such consent, or a written explanation for why such consent is being withheld, within *** of receiving Syndax’s request therefor. Genentech shall not unreasonably withhold its consent for such amendments.

- 8 -

2.5 Enrollment. Syndax shall not begin enrolling Subjects until after the full execution of this Agreement. Syndax shall enroll Subjects in compliance with Applicable Law and shall be responsible for tracking enrollment at Participating Sites. The total enrollment shall not exceed the maximum number of Subjects specified in the Protocol, unless such number is increased by a Protocol amendment.

2.6 Agreements with Project Participants. Syndax is solely responsible for negotiating and executing appropriate agreements with CROs, Investigators, Participating Sites, drug distributors and other Project Participants. Syndax shall ensure that (a) all such agreements include terms and conditions that are necessary for Syndax to comply with the terms and conditions of this Agreement (including the confidentiality provisions in Article 7); (b) all Project Participants are appropriately qualified, and Syndax has satisfied the requirements of Section 10.2 with respect to such Project Participants; and (c) the compensation being paid to a Participating Site under its agreement with Syndax for the Study constitutes the fair market value of the services to be provided. Syndax is solely responsible for managing the Project Participants, including monitoring the conduct of the Study at the Participating Sites. In no event shall any agreement with a Project Participant represent that any member of the Roche Group is a Sponsor.

2.7 Regulatory Matters.

(a) Generally. Syndax shall ensure that all directions from Regulatory Authorities and IRBs with jurisdiction over the Study are followed. Syndax is responsible for all regulatory obligations imposed on the Sponsor; no such obligations are transferred to any member of the Roche Group under this Agreement.

(b) Interactions with Regulatory Authorities. Notices, inquiries and correspondences that Syndax (or Project Participants) receive from a Regulatory Authority regarding the Study shall be handled in accordance with Section 10.3, subject to the provisions of this Section. If Syndax receives any comments or other inquiries from a Regulatory Authority regarding the Study that pertain specifically to the Genentech Compound, Syndax shall provide such inquiries to Genentech, and Genentech shall provide its responses to Syndax within the timeline imposed by the Regulatory Authority, and in no event later than *** from the date Genentech receives such inquiries from Syndax. Genentech shall have the right (but not the obligation) to participate in any discussions with a Regulatory Authority regarding matters related to the Genentech Compound, to the extent permitted by such Regulatory Authority.

(c) Rights of Reference. Promptly after the Effective Date, and during the Study, each Party shall provide a Right of Cross-Reference to the existing IND for its Compound to the extent necessary to allow the Study to be conducted under the Collaboration IND.

2.8 Documentation, Updates and Final Study Report.

(a) Documentation. Each Party shall maintain reports and documentation arising in connection with the Study in good scientific manner and in compliance with Applicable Law. Each Party shall provide to the other

- 9 -

Party all such reports and documentation arising from the Study (including reports of interim analyses, if applicable) reasonably requested to enable such other Party to comply with any of its legal, regulatory and/or contractual obligations, or any request by a Regulatory Authority, in all cases related to the Genentech Compound or the Syndax Compound, as applicable.

(b) Updates. Syndax shall provide written updates regarding the status of the Study (including enrollment status, project timelines, Genentech Compound inventory and Genentech Compound forecasting) to Genentech on a quarterly basis. At Genentech’s request, in lieu of a written update, Syndax shall provide such quarterly update to Genentech orally, either in person or by telephone.

(c) Final Study Report. Syndax shall use its best efforts to complete the Study as outlined in the Protocol. Syndax shall summarize the findings of the Study in a Final Study Report. Syndax shall provide the Final Study Report to Genentech within six (6) months after Database Lock. “Final Study Report” means a formal clinical study report documenting and summarizing the results and interpretation of the Study, including the trial design, trial objectives, patient assessment, data analysis, results, risk/benefit analysis, safety and effectiveness.

2.9 Genentech Study Responsibilities. In addition to Genentech’s obligations to supply the Genentech Compound under Section 4.2 and provide responses to Syndax pertaining to those Regulatory Authority inquiries specified under Section 2.7(b), Genentech shall provide and make available to Syndax necessary information about the Genentech Compound to conduct the Study, including to support interactions with Regulatory Authorities and IRBs. Genentech shall make available to Syndax safety data related to the Genentech Compound necessary to file the Collaboration IND and to conduct the Study.

2.10 Costs. Each Party shall perform its obligations under this Agreement at its own expense (e.g., performing the Sample Analyses under Section 5.2), including its internal costs. Except for the foregoing or as otherwise expressly provided in the Agreement (e.g., Genentech’s obligation to supply the Genentech Compound under Section 4.2), or agreed to in writing by the Parties, *** shall be *** responsible for the costs of the Study.

2.11 Additional Studies. If a Party would like to conduct additional clinical studies using the Combination, at the request of such Party, the Parties shall discuss in good faith the possibility of, and the terms and conditions for, conducting such clinical studies, including cost sharing, decision making and the supply of Compounds. This Section shall survive the expiration of this Agreement for a period of ***.

PRESS RELEASE

SYNDAX ENTERS CLINICAL TRIAL COLLABORATION IN CANCER IMMUNOTHERAPY COMBINING ENTINOSTAT AND ATEZOLIZUMAB

Phase 1b/2 trial with Genentech will assess the safety and efficacy of combining these investigational therapies for the treatment of triple-negative breast cancer

WALTHAM, Mass., August XX, 2015 – Syndax Pharmaceuticals, Inc., a privately held biopharmaceutical company focused on developing therapies for the treatment of cancer, announced today that it has entered into a clinical collaboration with Genentech, a member of the Roche Group, to evaluate the safety, tolerability and preliminary efficacy of Syndax’s entinostat, an oral small molecule that targets immune regulatory cells (myeloid-derived suppressor cells (MDSCs) and regulatory T cells (Tregs)), in combination with Genentech’s atezolizumab (MPDL3280A), a fully humanized monoclonal antibody targeting protein programmed cell death ligand 1 (PD-L1), in patients with triple-negative breast cancer. Triple-negative breast cancer is estimated to account for 10-20% of all diagnosed breast cancers and is characterized by a lack of expression of estrogen receptor (ER-), progesterone receptor (PR-) and HER2 (HER2-) on the breast cancer cells.

“Clinical development collaborations with industry leaders are an essential element of our strategy to realize the full potential of entinostat and position Syndax at the forefront of next-generation immuno-oncology therapy,” said ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇, M.D., Chief Executive Officer of Syndax. “This collaboration expands our emerging immuno-oncology program into an important new indication. We are looking forward to collaborating with Genentech to study atezolizumab and entinostat in a breast cancer population with few treatment options.”

Syndax will be responsible for conducting the Phase 1b/2 clinical trial in triple-negative breast cancer and the agreement includes a provision where the parties may extend the collaboration to include a Phase 3 clinical trial as well as additional trials in new indications of mutual interest.

Exhibit D-1
