principles and applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific
performance, injunctive relief or other equitable remedies and (iii) insofar as indemnification and contribution provisions may be limited by applicable law. 

(b)    The Company acknowledges and agrees that the representations contained in this
Section 3.2 shall not modify, amend or affect the Purchaser’s right to rely on the Company’s representations and warranties contained in this Agreement or any representations and warranties contained in any other
Transaction Documents or any other document or instrument executed and/or delivered in connection with this Agreement or the consummation of the transactions contemplated hereby. Notwithstanding the foregoing, for the avoidance of doubt, nothing
contained herein shall constitute a representation or warranty, or preclude any actions, with respect to locating or borrowing shares in order to effect Short Sales or similar transactions in the future. 

(c)    The Purchaser acknowledges its understanding that the offering and sale of the Shares is intended to be exempt from
registration under the Securities Act, by virtue of Section 4(a)(2) of the Securities Act and the applicable provisions of Regulation D promulgated thereunder (“Regulation D”) and that the Company is relying on the
Purchaser’s representations and warranties in connection with the Regulation D exemption. In furtherance thereof, the Purchaser represents and warrants to the Company as follows: 

(i)    The Purchaser is an accredited investor as defined in Rule 501(a) of Regulation D promulgated under the Securities
Act; 
 (ii)    The Purchaser realizes that the basis for exemption would not be available if the sale of Shares was
part of a plan or scheme to evade registration provisions of the Securities Act or any applicable state or federal securities laws; 

  
 12 

 (iii)    The Purchaser is acquiring the Shares solely for the
Purchaser’s own beneficial account, for investment purposes, and not with a view towards, or resale in connection with, any distribution of the Shares; 

(iv)    The Purchaser has the financial ability to bear the economic risk of its investment, has adequate means for
providing for its current needs and contingencies, and has no need for liquidity with respect to an investment in the Company; 

(v)    The Purchaser has such knowledge and experience in financial and business matters as to be capable of evaluating
the merits and risks of an investment in the Shares; 
 (vi)    The Purchaser has had a reasonable opportunity to ask
questions of and receive answers from a person or persons acting on behalf of the Company concerning the Shares and the business, financial condition, results of operations and prospects of the Company; and 

(vii)    The Purchaser is unaware of, and is in no way relying on, any form of general solicitation or general
advertising, including, without limitation, any article, notice, advertisement or other communication published in any newspaper, magazine or similar media or broadcast over television or radio, or electronic mail over the Internet, in connection
with the offer and sale of Shares and is not subscribing for Shares and did not become aware of the offer or sale of Shares through or as a result of any seminar or meeting to which the Purchaser was invited by, or any solicitation of a subscription
by, a person not previously known to the Purchaser in connection with investments in securities generally. 

(d)    Certain Transactions and Confidentiality. Other than consummating the transactions contemplated hereunder,
the Purchaser has not, nor has any Person acting on behalf of or pursuant to any understanding with the Purchaser, directly or indirectly, executed any purchases or sales, including Short Sales, of the securities of the Company during the period
commencing one day after the Purchaser first submitted a term sheet in writing to the Company setting forth the material terms of the transactions contemplated hereunder and ending immediately prior to the execution hereof. The Purchaser has
maintained the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this transaction) in accordance with that certain Non-Disclosure Agreement
between the Company and the Purchaser (the “NDA”). 
 (e)    Transfer Restrictions. The
Purchaser will not sell or otherwise transfer any Shares without registration under the Securities Act or an exemption therefrom, and fully understands and agrees that the Purchaser must bear the economic risk of its purchase because, among other
reasons, the Shares have not been registered under the Securities Act or under the securities laws of any state and, therefore, cannot be resold, pledged, assigned or otherwise disposed of unless they are subsequently registered under the Securities
Act and under the applicable securities laws of such states, or an exemption from such registration is available. In particular, the Purchaser is aware that the Shares are “restricted securities,” as such term is defined in Rule 144
promulgated under the Securities Act (“Rule 144”), and they may not be sold pursuant to Rule 144 unless all of the conditions of Rule 144 are met. The Purchaser 

  
 13 

 
understands that any sales or transfers of the Shares are further restricted by state securities laws and the provisions of this Agreement. The Purchaser understands that, subject to the
Purchaser’s rights set forth herein, the Company may establish procedures for approval of transfers, including transfers sought to be permitted under Rule 144, which may result in delays in desired sales or transfers by the Purchaser. 

(f)    Legends. The Purchaser understands and agrees that the Shares shall bear substantially the following legend
until such Shares shall have been registered under the Securities Act and effectively disposed of in accordance with a registration statement that has been declared effective 

THE SECURITIES REPRESENTED HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY
APPLICABLE STATE SECURITIES LAWS. SUCH SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT PURPOSES AND MAY NOT BE OFFERED FOR SALE, SOLD, DELIVERED AFTER SALE, TRANSFERRED, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT
FILED BY THE ISSUER WITH THE U.S. SECURITIES AND EXCHANGE COMMISSION COVERING SUCH SECURITIES UNDER THE SECURITIES ACT OR AN EXEMPTION FROM REGISTRATION.

constitutes, or contains, material, non-public information regarding the Company, the Company shall simultaneously file such material non-public information with the
Commission pursuant to a Current Report on Form 8-K. The Company understands and confirms that the Purchaser shall be relying on the foregoing covenant in effecting transactions in securities of the Company.

 4.5.    Indemnification of Purchaser. Subject to the provisions of this Section 4.5,
the Company will indemnify and hold the Purchaser and its directors, officers, shareholders, members, partners, employees and agents (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of
such title or any other title), each Person who controls the Purchaser (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, shareholders, agents, members, partners or
employees (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title) of such controlling persons (each, a “Purchaser Party”) harmless from any
and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation that any the Purchaser
Parties may suffer or incur as a result of or relating to (a) any breach of any of the representations, warranties, covenants or agreements made by the Company in this Agreement or in the other Transaction Documents, (b) any action
instituted against the Purchaser Party in any capacity, or any of them or their respective Affiliates, by any stockholder of the Company who is not an Affiliate of the Purchaser Party or any other Purchaser Party, with respect to any of the
transactions contemplated by the Transaction Documents (unless such action is based upon a 

  
 15 

 
material breach of the Purchaser Party’s representations, warranties or covenants under the Transaction Documents or any agreements or understandings the Purchaser Party may have with any
such stockholder or any violations by the Purchaser Party of state or federal securities laws or any conduct by the Purchaser Party which is finally judicially determined to constitute fraud, gross negligence or willful misconduct), or (c) in
connection with any registration statement of the Company providing for the resale by the Purchaser of Shares issued pursuant to this Agreement, (i) any untrue or alleged untrue statement of a material fact contained in such registration
statement, any prospectus or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein (in the case of any prospectus or supplement thereto, in the light of the circumstances under which they were made) not misleading, except to the extent, but only to the extent, that such untrue statements or
omissions are based solely upon information regarding the Purchaser Party furnished in writing to the Company by the Purchaser Party expressly for use therein, or (ii) any violation or alleged violation by the Company of the Securities Act, the
Exchange Act or any state securities law, or any rule or regulation thereunder in connection therewith. If any action shall be brought against any Purchaser Party in respect of which indemnity may be sought pursuant to this Agreement, the Purchaser
Party shall promptly notify the Company in writing, and the Company shall have the right to assume the defense thereof with counsel of its own choosing reasonably acceptable to the Purchaser Party. Any Purchaser Party shall have the right to employ
separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the Purchaser Party except to the extent that (x) the employment thereof has been specifically
authorized by the Company in writing, (y) the Company has failed after a reasonable period of time to assume such defense and to employ counsel or (z) in such action there is, in the reasonable opinion of counsel, a material conflict on
any material issue between the position of the Company and the position of the Purchaser Party, in which case the Company shall be responsible for the reasonable fees and expenses of no more than one such separate counsel. The Company will not be
liable to any Purchaser Party under this Agreement (1) for any settlement by a Purchaser Party effected without the Company’s prior written consent, which shall not be unreasonably withheld or delayed; or (2) to the extent, but only
to the extent that a loss, claim, damage or liability is attributable to any Purchaser Party’s breach of any of the representations, warranties, covenants or agreements made by the Purchaser Party in this Agreement or in the other Transaction
Documents. The indemnification required by this Section 4.5 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or are incurred. The
indemnity agreements contained herein shall be in addition to any cause of action or similar right of any Purchaser Party against the Company or others and any liabilities the Company may be subject to pursuant to law. 

4.6.    Subsequent Equity Sales. From the date hereof until 365 days after the Closing Date, the Company shall not
issue, enter into any agreement to issue or announce the issuance or proposed issuance of any shares of Common Stock or Common Stock Equivalents except as provided for in the Shareholder Rights Agreement. 

4.7.     No Short Sales. From the execution of this Agreement until the Per Share Purchase Price is decided,
i.e. the previous business day of the Closing Date, the Purchaser shall not execute any securities transaction that may contravene any relevant regulations, including Short Sales of any of the Company’s securities. 

  
 16 

 4.8.    Registration Statement. Except as otherwise required by
Rule 144, in order to assist with the elimination of any restriction (including but not limited to such restrictions arising from or in connection with (a) the Purchaser becoming an Affiliate of the Company (as determined by the Shareholder in
its sole discretion) and (b) the Shares being “restricted securities”, as such term is defined in Rule 144) whatsoever on the Purchaser from trading in the securities of the Company (including, but not limited to, the Shares), the
Company shall (i) file with the Commission on or before the Closing Date a registration statement on Form S-3 in order to register the sale of the Shares, (ii) use commercially reasonable best
efforts to cause such registration statement to become effective within 60 calendar days (or, in the event of a full review, 90 calendar days) following the Closing Date, and (iii) keep such registration statement effective at all times until
the later of (x) the Purchaser no longer owning any Shares or (y) the Purchaser no longer being an Affiliate of the Company.

including recovery of damages, the Purchaser and the Company will be entitled to seek specific performance under the Transaction Documents. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of

federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not

 Exhibit 10.2 

SHAREHOLDER RIGHTS AGREEMENT 

THIS SHAREHOLDER RIGHTS AGREEMENT (this “Agreement”), is made and entered into as of January 11, 2021 by and among
MediciNova, Inc., a Delaware corporation, (the “Company”) and 3D Opportunity Master Fund, a Cayman Islands exempt company (the “Shareholder”). 

RECITALS 
 WHEREAS,
the Company and the Shareholder are entering into a certain Securities Purchase Agreement as of the date hereof for the investment of approximately $20 million in the securities of the Company subject to the terms and conditions of the
Securities Purchase Agreement. 
 WHEREAS, in order to induce the Shareholder to invest funds in the Company pursuant to the
Securities Purchase Agreement, the Shareholder and the Company hereby agree that the Shareholder shall have the rights and privileges set forth in this Agreement. 

NOW, THEREFORE, the parties hereby agree as follows: 
  

	1.	 Definitions. For purposes of this Agreement: 

1.1    “Affiliate” means, with respect to any specified Person, any other Person who, directly or
indirectly, controls, is controlled by, or is under common control with such Person, including, without limitation, any general partner, managing member, officer, director or trustee of such Person, or any investment fund or separately managed
account now or hereafter existing that is controlled by one (1) or more general partners, managing members or investment adviser of, or shares the same management company or investment adviser with, such Person. 

1.2    “Board” or “Board of Directors” means the board of directors of the Company. 

1.3    “Business Day” means any day except any Saturday, any Sunday, any day which is a federal legal
holiday in the United States or any day on which banking institutions in the State of New York are authorized or required by law or other governmental action to close. 

1.4    “Change of Control” means a transaction or series of related transactions in which a person, or a
group of related persons, acquires from Shareholders of the Company shares representing more than fifty percent (50%) of the outstanding voting power of the Company. 

1.5    “Common Stock” means shares of the Company’s common stock, par value $0.001 per share. 

1.6    “Person” means any individual, corporation, partnership, trust, limited liability company,
association or other entity. 
 1.7    “Restated Certificate” means the Company’s Restated
Certificate of Incorporation, as amended and/or restated from time to time. 
 1.8    “SEC” means the
U.S. Securities and Exchange Commission. 

  
 1 

 1.9    “Shares” means and shall include any securities
of the Company that the holders of which are entitled to vote, including, without limitation, all shares of Common Stock, by whatever name called, now owned or subsequently acquired by Shareholder, however acquired, whether through stock splits,
stock dividends, reclassifications, recapitalizations, similar events or otherwise. 
  

	2.	 Observer Rights. 

2.1    Right of Appointment. The Company hereby grants the Shareholder the option and right to appoint (such right,
the “Observer Appointment Right”) a representative of the Shareholder’s sole choice (the “Board Observer”) to attend all meetings of the Board (both regular and special), should the Shareholder so decide, and,
upon the written request of the Shareholder, receive minutes of such meetings. The Observer Appointment Right may only be exercised during the six (6) month period following the first anniversary of this Agreement; provided that the
Observer Appointment Right is contingent upon the Shareholder having beneficial ownership of five percent (5%) or more of the outstanding Shares of the Company (the “Ownership Threshold”) at the time of appointment. The Shareholder
may exercise the Observer Appointment Right pursuant to the provisions of Section 2.2 below. The Board Observer, once appointed, shall serve for a period equal to the shorter of two (2) years or the date at which the
Shareholder’s holdings fall below the Ownership Threshold through disposition of Shares by the Shareholder (the “Observation Period”). For avoidance of doubt, the Shareholder shall not be deemed to be below the Ownership
Threshold if its beneficial ownership is decreased due to an issuance of Shares by the Company and the Shareholder shall maintain its Observer Appointment Right unless its own disposition of Shares causes it to fall below the Ownership Threshold.
The Board Observer shall not constitute a member of the Board and shall not be entitled to vote on, or consent to, any matters presented to the Board. 

2.2    Notice of Appointment. To exercise the Observer Appointment Right, the Shareholder shall deliver written
notice to the Company affirmatively appointing a representative to be the Board Observer. Upon delivery by Shareholder, and until the earliest of (i) the resignation or death of such individual serving as the Board Observer, (ii) the
removal of such individual serving as the Board Observer by the Shareholder, as evidenced by written notice delivered by the Shareholder to the Company or (iii) the end of the Observation Period, such representative shall be the Board Observer.
The Shareholder may remove or change the individual serving as the Board Observer for any reason, with or without cause in its sole discretion. If for any reason, the individual serving as the Board Observer is removed or otherwise ceases to serve
as the Board Observer, the Shareholder may, by written notice in accordance with this Section 2.2, appoint a new Board Observer during the remaining portion of the Observation Period. 

2.3    Conduct of Meetings. The Company shall (i) provide the Shareholder and the Board Observer written
notice of each meeting of the Board (both regular and special), at approximately the same time as notice is given to the members of the Board and (ii) on a
meeting-by-meeting basis, if the Shareholder notifies the Company that the Board Observer will attend such meeting, provide the Board Observer with all rights to attend
(whether in person or by telephone or other means of electronic communication as provided to each member of the Board) such meeting of the Board. Subject to the provisions of Section 2.4 below, if the

  
 2 

 
Shareholder desires to have the Board Observer attend any such meeting of the Board, the Shareholder shall within two (2) Business Days of receipt of written notice of such meeting, notify
the Company that the Board Observer will attend such meeting. Notwithstanding any rights to be granted or provided to the Board Observer hereunder, the Board reserves the right to exclude the Board Observer from access to any material or meeting or
portion thereof if the Board reasonably determines, in good faith after consultation with outside counsel, that such access (a) could be reasonably likely to adversely affect the attorney-client privilege
between the Company and its counsel, (b) would result in disclosure of trade secrets or other highly confidential proprietary information to the Board Observer (unless covered by an enforceable confidentiality agreement) or (c) could
result in a conflict of interest with the Company. 
 2.4    Receipt of Material
Non-Public Information by Board Observer. Shareholder and the Company covenant that prior to the attendance of the Board Observer at any meeting of the Board they shall agree to appropriate processes and
procedures regarding the access by the Board Observer to material non-public information with respect to the Company (“MNPI”) in order to comply with the internal compliance processes of the
Shareholder. 
 2.5    Compliance Process. Except to the extent that may otherwise be required by applicable law,
including, without limitation, the provisions of Section 5.1 below, and subject to the provisions of Section 2.4 above, the Company shall abide by all internal compliance processes of the
Shareholder (as notified in writing to the Company) with respect to all notices and information (including minutes of meetings and other documents) delivered or communicated to the Shareholder and the Observer in connection with
Section 2 of this Agreement. 
  

	3.	 Rights to Future Stock Issuances. 

3.1    Right of First Offer. Until January 11, 2022, the Company shall not undertake any capital
financing activities (each round of such activities, a “Capital Raising Round”) unless, in the reasonable view of the Company, such Capital Raising Round is reasonably likely to significantly enhance stockholder value;
provided, however, that in such case the Company shall first provide written notice to the Shareholder of the Company’s needs and intentions with respect to a Capital Raising Round, but shall not include any information that could
be deemed MNPI (the “Right of First Offer Notice”) and offer the Shareholder (before any other party) the right to participate either by itself or with any of its Affiliates in such Capital Raising Round (the “Right of First
Offer”). After receipt of the Right of First Offer Notice, the Shareholder may elect for the Company to provide a summary of the proposed terms and conditions of such Capital Raising Round. 

3.2    Third Party Offers. 

(a)    Until January 11, 2022, in the event that the Company receives any written or oral proposal (the “Third
Party Proposal”) from a third party to provide additional capital or equity or debt financing, the Company agrees that it shall not consider such Third Party Proposal unless, in the reasonable view of the Company, such Capital
Raising Round is reasonably likely to significantly enhance stockholder value; provided, however, that in such case the Company shall notify the Shareholder within two (2) Business Days of the receipt of the Third Party

  
 3 

 
Proposal (without including any material, non-public information). The Shareholder shall, within three (3) Business Days of such notice, provide
notice to the Company regarding whether it wishes to receive copies of all documents received by the Company relating to the Third Party Proposal, including, without limitation, a complete and accurate description of the Third Party Proposal and all
amendments, revisions, and supplements thereto (the “Proposal Documents” and such notice the “Shareholder Response Notice”). Following receipt of the Shareholder Response Notice, the Company shall immediately
provide the Proposal Documents to the Shareholder. 
 (b)    Following receipt of the Proposal Documents from the
Company, the Shareholder shall have the right (the “Right of First Look”), but not the obligation, to invest in the Company on the terms and conditions as set forth in the Proposal Documents (whether by itself to the exclusion of
the third party or together with the third party) upon written notice to the Company that the Shareholder is exercising the Right of First Look provided pursuant to this Section 3.2. In furtherance of the Right of First
Look, the Company agrees that it will (i) cooperate and assist the Shareholder in conducting a due diligence investigation of the Company and its corporate and financial affairs, and (ii) promptly provide the Shareholder with information
and documents that the Shareholder may reasonably request so as to allow the Shareholder to make an informed investment decision. 

3.3    Apportionment. Should the Shareholder exercise either the Right of First Offer or Right of First Look, the
Shareholder shall be entitled to apportion the Right of First Offer or Right of First Look (as the case may be) in such proportions as it deems appropriate, among itself and its Affiliates.  

3.4    Compliance Process. Except to the extent that may otherwise be required by applicable law, including,
without limitation, the provisions of Section 5.1 below, the Company shall abide by all internal compliance processes of the Shareholder (as notified in writing to the Company) with respect to all notices and information
(including Proposal Documents and other documents) delivered or communicated to the Shareholder in connection with Section 3 of this Agreement. 

4.    MNPI and Compliance Processes. 

4.1    MNPI. Subject to the provisions of this Section 4.1 and
Section 2.4 above, the Company shall use its commercial reasonable efforts not to provide any MNPI to the Shareholder or the Board Observer. However, should the Company provide any MNPI to the Shareholder or the Board
Observer (whether pursuant to Section 2.4, this Section 4.1 or otherwise), the Company shall take all necessary action (which includes but not limited to the public disclosure of such MNPI) to
ensure, at the earliest possible time, that the Shareholder be free from any prohibition or restriction in respect of transactions of securities in or related to the Company. 

4.2    Compliance Processes. Except to the extent that may otherwise be required by applicable law, including,
without limitation, the provisions of Section 5.1 below, and subject to the provisions of Section 2.4 and Section 4.1 above, the Company shall comply with all internal
compliance processes of the Shareholder (as notified in writing to the Company) with respect to 

  
 4 

 
notices and information delivered or communicated to the Shareholder by the Company, including without limitation, the provisions of Sections 2 and 3 above, in order (i) to
prevent any inadvertent receipt of MNPI by the Shareholder or the Board Observer, (ii) to ensure the mutual recognition and awareness of any MNPI communicated by the Company to the Shareholder or the Board Observer, and the exact of the scope
of such MNPI, (iii) for the Shareholder to restrict itself in a timely manner from transactions of securities in or related to the Company whilst in possession of MNPI, and (iv) for the Company to take reasonable action to free the
Shareholder from any prohibition or restriction in respect of transactions of securities in or related to the Company. 
  

	5.    Announcement.	 

5.1    The Shareholder hereby acknowledges that the terms of this Agreement and the Securities Purchase Agreement will be
disclosed in the public filings of the Company with the SEC. The Company and the Shareholder shall consult with each other regarding any SEC filings or disclosure related to the Shareholder’s investment in the Company. 

5.2    Subject to the limitations set forth in Section 5.1 above, no other announcement
regarding the Shareholder in a press release, conference, advertisement, announcement, professional or trade publication, mass marketing materials or otherwise to the general public may be made without the Shareholder’s prior written consent,
