 Exhibit 10.1 

SEPARATION, TRANSITION, AND RELEASE OF CLAIMS AGREEMENT 

This Separation, Transition and Release of Claims Agreement (the “Agreement”) is made by and between Oliver S. Fetzer, Ph.D (the
“Employee”) and Cerulean Pharma Inc. (“Cerulean” or the “Company”) (together, the “Parties”). 

WHEREAS, the Employee has been employed as the President and Chief Executive Officer of the Company since 2009; 

WHEREAS, the Parties entered into an Amended and Restated Executive Employment Agreement effective as of June 24, 2014 (the
“Employment Agreement”); 
 WHEREAS, the Employee is resigning from his employment with the Company and as an officer and
director of the Company and any affiliate, in each case effective October 29, 2014 (the “Separation Date”); and 

WHEREAS, in the interest of an amicable departure and transition, and in exchange for, among other things, the Employee entering into
and complying with this Agreement and providing the post-employment assistance set forth below, the Company is providing the Employee with consideration set forth in this Agreement. 

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Parties hereby
agree as follows: 
 1. Resignation from Employment and Director and Officer Positions. As of the Separation Date, the
Employee hereby resigns from his employment with the Company and from his positions as a member of the Company’s Board of Directors and as an officer of the Company, as well as from any other director or officer positions he holds with any of
the Company’s subsidiaries or entities affiliated with the Company. The Employee agrees to execute and deliver any documents reasonably necessary to effectuate such resignations, provided that nothing in any such document is inconsistent with
any terms set forth in this Agreement. Should the Employee fail to promptly submit on the Separation Date his resignation as an officer or director or execute any documents requested by the Company or any Company affiliate to effectuate the
Employee’s resignation from any and all officer and director positions, the Employee hereby irrevocably appoints the Company to be his attorney-in-fact to execute any documents and do anything in his name to effect such resignation. A written
notification signed by a director or duly authorized officer of the Company that any instrument, document or act falls within the authority conferred by this subsection will be conclusive evidence that it does so. The Company will prepare any
documents, pay any filing fees, and bear any other expenses related to this section.  
 2. Post-Employment Consulting and
Assistance. In order to assist the Company in making a smooth transition to new leadership, the Employee agrees that, for one hundred and eighty (180) days following the Separation Date (the “Consulting Period”), he shall make
himself reasonably available by telephone or e-mail from time to time, upon reasonable notice and on an as-needed basis, to consult with the Company and to provide any reasonable information and/or guidance that the Company may request concerning
his former duties and responsibilities and/or his knowledge of the Company’s business and operations (the 







 
“Post-Employment Assistance”). The Employee acknowledges and agrees that the consideration set forth in this Agreement is being provided, in part, as consideration for this
Post-Employment Assistance, and that he will not be entitled to receive any additional compensation or benefits for such assistance. 

3. Stock Options. The Employee and Company hereby agree that, notwithstanding any term of any outstanding stock option held by
the Employee or in any other agreement between the Company and the Employee, any and all such stock options shall cease vesting as of the Separation Date and will remain exercisable during the Consulting Period, but not for any period following the
Consulting Period (and in no event later than the Final Exercise Date (as defined in the Employee’s applicable option agreement(s))). 

4. Releases of Claims. 

(a) By the Employee - In exchange for the consideration set forth in this Agreement, which the Employee acknowledges he would not
otherwise be entitled to receive, the Employee hereby fully, forever, irrevocably and unconditionally releases, remises and discharges the Company, its affiliates, subsidiaries, parent companies, predecessors, and successors, and all of its and
their respective past and present officers, directors, stockholders, partners, members, employees, agents, representatives, plan administrators, attorneys, insurers and fiduciaries (each in their individual and corporate capacities) (collectively,
the “Released Parties”) from any and all claims, complaints, demands, actions, causes of action, suits, rights, debts, sums of money, costs, accounts, reckonings, covenants, contracts, agreements, promises, doings, omissions, damages,
executions, obligations, liabilities, and expenses (including attorneys’ fees and costs), of every kind and nature, whether known or unknown, that the Employee ever had or now has against any or all of the Released Parties, including, but not
limited to, any and all claims arising out of or relating to the Employee’s employment with and/or service as an officer and/or director of the Company or any affiliate, or to the Employee’s separation from employment with and/or service

Opportunity Commission or a state fair employment practices agency (except that the Employee acknowledges that he may not recover any monetary benefits in connection with any such claim, charge or proceeding and further waives any rights or claims
to any payment, benefit, attorneys’ fees or other remedial relief in connection with any such claim, charge or proceeding), or releases, remises or discharges any rights of the Employee to (i) vested ownership interests in the Company,

the Company’s or any affiliate’s business affairs or financial condition; provided, however, that nothing herein shall be construed as preventing the Employee from making truthful disclosures to any governmental entity or in any litigation
