Sanofi shall be responsible for preparing  all such assignment and other documents and for recording the assignment to Sanofi of the Mir-21  Product Specific Patents with the relevant patent offices, at Sanofi’s sole expense.  From and after  the First Amendment Date, Sanofi shall be solely responsible for the prosecution, maintenance,  enforcement and defense of the Mir-21 Product Specific Patents (together with any and all Patents  corresponding to the Mir-21 Product Specific Patents that may be filed or issued after the First  Amendment Date), throughout the world, at Sanofi’s sole expense and discretion, and  notwithstanding anything to the contrary set forth in the Agreement, ARTICLE 8 of the Agreement  shall not apply to any Mir-21 Product Specific Patent.                                                    ***Confidential Treatment Requested                                          5

Sanofi  shall compensate Regulus for such technical assistance at the FTE-Day Rate and shall reimburse  Regulus for out-of-pocket costs (including, without limitation, travel and lodging costs) incurred  by Regulus personnel in providing such assistance; provided, however, that (a) the first  [...***...] hours of such technical assistance shall be provided free of charge (other than  reimbursement of out-of-pocket costs), and (b) “technical assistance” as used in this  Paragraph 5.8 does not include the work required by Regulus to fulfill its obligations under the  other sections of this Paragraph 5.  Regulus will invoice Sanofi on a monthly basis for such  assistance provided and reimbursable costs incurred pursuant to this Paragraph 5.8 (along with  reasonable supporting documentation of such out-of-pocket costs), and Sanofi shall pay all  amounts (except to the extent disputed in good faith) set forth in any such invoice within  [...***...] days of receipt thereof.  After the Technical Assistance Period, Regulus may provide  additional technical assistance as described above in this Paragraph 5.8 upon Sanofi’s reasonable  request, subject to compensation by Sanofi at the FTE-Day Rate and reimbursement by Sanofi of  Regulus’ out-of-pocket costs (including, without limitation, travel and lodging costs) incurred in                                                 ***Confidential Treatment Requested                                          8

(a)   At Sanofi’s request, Regulus shall take all actions required to either   terminate, or assign to Sanofi, any Contract to which Regulus is a party or to which Regulus or  any of its assets or properties is bound, in each case, relating solely to the Mir-21 POC Programs  or any Mir-21 Compounds and Mir-21 Products (the “Mir-21 Contracts”); provided, however,  that the defined term “Mir-21 Contracts” shall exclude the Max Planck Agreement and the  Wurzburg Agreement (which agreements will be addressed pursuant to Paragraph 5.4 of this  First Amendment).  In addition, Sanofi may request the termination or assignment of any work  orders that are not under Mir-21 Contracts, but that relate solely to the Mir-21 POC Programs or  any Mir-21 Compounds and Mir-21 Products (“Mir-21 Work Orders”), and Regulus shall take  all actions required to assign any such Mir-21 Work Orders to Sanofi.  Regulus shall use its best  efforts to facilitate any negotiations with the counterparties to such Mir-21 Contracts or Mir-21   Work Orders, in each case, to the extent related to any such assignment, provided that the   foregoing shall not be construed to require Regulus to pay to such counterparties any   consideration to the extent related to such assignment that is not otherwise payable by Regulus.               (b)   Sanofi hereby assumes all obligations of Regulus under any Mir-21  Contract assigned to Sanofi (each, an “Assigned Mir-21 Contract”) that arise after the date of  assignment of such Assigned Mir-21 Contract, and Regulus shall remain responsible for all  obligations arising under such Assigned Mir-21 Contract through the date of assignment.  If  Sanofi receives any invoice from the counterparty to any Assigned Mir-21 Contract for any  amount that became due or includes obligations that accrued under such Assigned Mir-21  Contract on or before the date of assignment, then Sanofi shall promptly provide a copy of such  invoice to Regulus, and at Sanofi’s discretion, either (i) Regulus shall pay such invoiced amount  to such counterparty on or before the due date for payment of such invoice, or (ii) Sanofi can pay  the invoiced amount to such counterparty, and in such case, Regulus shall reimburse Sanofi for  such amount or the allocated amount of such invoice for which Regulus is responsible within  [...***...] days after receipt of an invoice from Sanofi for such amount, provided that if Regulus  fails to timely pay or reimburse such amount, then Sanofi may off-set such amount against any  of its payment obligations due under Paragraphs 6.1 and 6.2 of this First Amendment.  Any  invoice from the counterparty to any Assigned Mir-21 Contract that includes obligations accrued  before and after the date of assignment shall be allocated between Sanofi and Regulus and paid  as provided above.  If Regulus receives any invoice from the counterparty to any Assigned  Mir-21 Contract for any amount that became due under such Assigned Mir-21 Contract after the  date of assignment, then Regulus shall promptly provide a copy of such invoice to Sanofi with  payment of any amounts listed in such invoice that accrued prior to the date of such assignment,  and then Sanofi shall be responsible for paying such invoice.           5.10  Closing Certain Clinical Trial Sites.  Promptly after the First Amendment Date,  Regulus will close, or cause its Third Party vendors to close, the Clinical Trial Sites (to the  extent relating to the Mir-21 POC Programs) listed on Schedule 5.10 accordance with all  Applicable Laws.                                                   ***Confidential Treatment Requested                                          9

Notwithstanding anything to the contrary contained herein, for    the 24-month period beginning on the Technology Transfer and Stand-by Letter Date, if Sanofi   discovers Regulus has either provided incorrect, inaccurate or incomplete information required to   be provided under this Article 5, or otherwise failed to perform its duties under this Article 5,   then upon written notice by Sanofi to Regulus, Regulus shall correct any such incorrect,   inaccurate or incomplete information, and cure any failure to perform.      6.

Each of the milestone payments set forth below in this Paragraph 6.2 shall be payable only one   time, and only for the first achievement of the applicable milestone event.

(a)   Sections 6.5, 6.6, 6.7, 6.8.3, 6.9.1, 6.9.2 and 6.14 of the Agreement shall be   inapplicable to the Mir-21 POC Programs, Sanofi Mir-21 Fibrosis POC Program, Mir-21   Compounds and Mir-21 Products.

(f)   Regulus has not received written notice of, and is not subject to, any  material adverse inspection, finding of non-compliance, compelled or voluntary recall,  investigation, penalty for corrective or remedial action or other compliance or enforcement  action, in each case relating to the Mir-21 POC Programs or any Mir-21 Compounds and Mir-21  Products or to the facilities of Regulus where the Mir-21 POC Programs or any development  activities with respect to Mir-21 Compounds and Mir-21 Products were conducted, by the FDA  or any other Governmental Authority.  There are no pending or threatened Legal Proceedings by  the FDA or any other Governmental Authority against Regulus relating to the Mir-21 POC  Programs or any Mir-21 Compounds and Mir-21 Products or to the facilities of Regulus where  the Mir-21 POC Programs or any development activities with respect to Mir-21 Compounds and  Mir-21 Products were conducted.                                         16

To the Knowledge of Regulus, (i) no CRO has received written notice of, and is not  subject to, any material adverse inspection, finding of non-compliance, compelled or voluntary  recall, investigation, penalty for corrective or remedial action or other compliance or  enforcement action, in each case, relating specifically to the Mir-21 Fibrosis POC Program or  any Mir-21 Compounds and Mir-21 Products developed by or on behalf of Regulus in  connection with the Mir-21 Fibrosis POC Program and (ii) there are no pending or threatened  Legal Proceedings by the FDA or any other Governmental Authority against any CRO relating to  the Mir-21 Fibrosis POC Program or any Mir-21 Compounds or Mir-21 Products developed by  or on behalf of Regulus in connection with the Mir-21 Fibrosis POC Program or to the facility of  CRO in which any such Mir-21 Compound or Mir-21 Product is manufactured, packaged or  stored.                (h)   Schedule 10.2(h) sets forth a list of all clinical trials and preclinical  studies conducted by or under the direction of Regulus related to the Mir-21 POC Programs or  any Mir-21 Compounds or Mir-21 Products.  Regulus shall make available to Sanofi true, correct  and complete materials relating to all such clinical trials and preclinical studies conducted in  connection with the Mir-21 Fibrosis POC Program that are in its possession and control pursuant  to the format and timelines set forth in Paragraph 5.3 and, upon Sanofi’s written request, will  make available to Sanofi true, correct and complete materials relating to any such listed study  conducted in connection with the Mir-21 Oncology POC Program that are in its possession and  control.

(j)   Regulus has provided to Sanofi true, complete and unredacted copies of  the Founding Company License Agreement (including all amendments thereto), the Max Planck  Agreement and the Wurzburg Agreement, each as in effect as of the First Amendment Date.  The  financial terms set forth in the Max Planck Agreement and the Wurzburg Agreement constitute  the only financial obligations of Regulus to Max Planck and Wurzburg, respectively, with  respect to any Mir-21 Compound or Mir-21 Product, including the development or  commercialization thereof.  As of the Amendment Date, Schedule 10.2(j) sets forth all In- License Royalties, In-License Milestones and Other In-License Payments that could become due  to Existing Third Party Licensors, as a result of the Development or Commercialization of Mir  21 Products by Sanofi or any of its Affiliates or sublicensees.                 (k)   Schedule 10.2(k) sets forth a true and complete list of the Mir-21 Product  Specific Patents. Other than the Mir-21 Product Specific Patents, Regulus does not have any  ownership interest in any Product Specific Patents directed to Mir-21 or to any Mir-21  Compound or Mir-21 Product.                                          17

On February 4, 2014, Regulus entered into that certain Second Amended and Restated Collaboration   and License Agreement (the “Sanofi-Regulus License”) with Sanofi, a company organized under   the laws of France, having a place of business at 54, rue la Boétie, 75008, Paris, France, registered in                                                                                       





 






     the Paris Trade and Company Register under no. 395 030 844 (“Sanofi”), pursuant to which, among   other things, Regulus assumed responsibility for all activities under each POC Program Plan (other   than Sanofi Program Activities) through the Achievement of Proof of Concept (each as defined in   the Sanofi-Regulus License).  Regulus has now suspended the Mir-21 Fibrosis POC Program and   has requested that Sanofi amend, and Sanofi has agreed to amend, the Sanofi-Regulus License as it  pertains to the Mir-21 POC Programs, Mir-21 Compounds and Mir-21 Products, to provide for,   among other things: (a) Sanofi to take responsibility for the obligations of Regulus under the Sanofi- Regulus License with respect to the Mir-21 Fibrosis POC Program, Mir-21 Compounds and Mir-21  Products, including the administration and expense of clinical trials related to the Mir-21 Fibrosis  POC Program (each as defined in the Sanofi-Regulus License); and (b) except as set forth in Section   8 of this Letter Agreement, the license and sublicense granted by Regulus to Sanofi with respect to   Mir-21 Compounds and Mir-21 Products to be royalty-free.        As a condition to entering into the amended Sanofi-Regulus License (once amended, the “Amended   Sanofi-Regulus License”), Sanofi requests that Regulus and each of the Licensors execute this letter  agreement (this “Letter Agreement”) where indicated below, memorializing their agreement to the  following:     Term. The provisions of this Letter Agreement shall be effective from the date of this Letter   Agreement written above. This Letter Agreement shall terminate immediately upon (a) Sanofi   providing each of the Licensors with an Option Declination Notice as set forth in Section 0 hereof or   (b) Sanofi and each of the Licensors executing a New License Agreement as set forth in Section 0   hereof.      No Consent Required to Sublicense. To the extent that the Licensors’ consent is required in order for   Regulus to sublicense any of the rights granted by Regulus to Sanofi in the Amended Sanofi- Regulus License, each Licensor hereby acknowledges that Regulus may grant such sublicenses to  Sanofi and hereby approves the sublicensing of such rights to Sanofi.      No Opt-In Right. Each Licensor acknowledges that Regulus’ decision to suspend the Mir-21 Fibrosis   POC Program and request that Sanofi amend the Sanofi-Regulus License to take responsibility for   Regulus’ obligations under the Sanofi-Regulus License with respect to the Mir-21 Fibrosis POC   Program, Mir-21 Compounds and Mir-21 Products, including the administration and expense of   clinical trials related to the Mir-21 Fibrosis POC Program (each as defined in the Sanofi-Regulus   License), does not give either of the Licensors the right to make an Opt-In Election (as defined in the   Alnylam-Ionis License) under Section 5 (Right to Opt-In) of the Alnylam-Ionis License and that   neither of the Licensors will make any such claim with respect to the Mir-21 Fibrosis POC Program  (as defined in the Sanofi-Regulus License) now or at any time in the future.       No Breach by Regulus. Each Licensor confirms that, as of the date of this Letter Agreement: (a) the   Alnylam-Ionis License remains in full force and effect; (b) such Licensor has not given any notice to   Regulus, and is not otherwise aware, of any breach by Regulus under the Alnylam-Ionis License;  and (c) such Licensor has not taken any action or omitted to take any action that could be deemed a  breach of its obligations under the Alnylam-Ionis License.                                                                                                                                                                          





 






  Amendments to Alnylam-Ionis License. Regulus shall give prompt written notice to Sanofi, together with  a written summary of outstanding issues if Sanofi so requests, of any notice received from or given to the  Licensors or either of them of any proposed amendments or proposed modifications of, or any proposed  waivers under, the Alnylam-Ionis License.  Except in the case of an uncured material breach by Sanofi or  Regulus, Regulus and the Licensors agree that they will not amend the Alnylam-Ionis License so as to  terminate or diminish the rights granted to Regulus under the Alnylam-Ionis License and sublicensed by  Regulus to Sanofi under the Amended Sanofi-Regulus License, if any, in a manner that would diminish or  undermine Sanofi’s rights under the Sanofi-Regulus License or this Letter Agreement without the prior  written consent of Sanofi.    Breach of the Alnylam-Ionis License. In the event of any breach by Regulus of the Alnylam-Ionis License  that gives rise to the Licensors’ right to terminate the Alnylam-Ionis License, each Licensor shall  promptly provide written notice to Sanofi of such breach (such notice to be provided concurrently with  the first notice to Regulus of such breach), and Sanofi shall have the right, but not the obligation, to  attempt to cure such breach on behalf of Regulus within the time periods set forth in the Alnylam-Ionis  License. During the cure periods set forth in the Alnylam-Ionis License, the Licensors shall not terminate  the Alnylam-Ionis License with respect to Regulus as a result of such breach.      Direct License Upon Termination of the Alnylam-Ionis License. In the event that the Alnylam-Ionis  License terminates for any reason, including material breach by Regulus, each Licensor shall promptly  notify Sanofi and Sanofi shall have the right and option to obtain directly from the Licensors, acting  jointly, a license under the Licensed IP (as defined in the Alnylam-Ionis License) with respect to Mir-21  Compounds and Mir-21 Products on substantially the same terms and conditions as set forth in the  Alnylam-Ionis License, as amended by Section 0 of this Letter Agreement (such right, the “License  Option”), including with respect to the rights granted to Regulus in Section 2.2(b) of the Alnylam-Ionis  License.  Sanofi may exercise the License Option by providing a written notice to the Licensors thereof  (the “Option Election Notice”) within [...***...] ([...***...]) days from the date that a Licensor first  notifies Sanofi that the Alnylam-Ionis License has terminated (the “Alnylam-Ionis License Termination  Date”). If Sanofi elects not to exercise the License Option, it shall provide written notice thereof (the  “Option Declination Notice”) to the Licensors within [...***...] ([...***...]) days from the Alnylam- Ionis License Termination Date. If Sanofi does not provide an Option Election Notice to the Licensors  within [...***...] ([...***...]) days from the Alnylam-Ionis License Termination Date, then Sanofi will  be deemed to have delivered the Licensors an Option Declination Notice. If Sanofi exercises the License  Option, then the Licensors shall enter into an exclusive license agreement directly with Sanofi (the “New  License Agreement”) under the Licensed IP (as defined in the Alnylam-Ionis License) with respect to  Mir-21 Compounds and Mir-21 Products that was licensed to Regulus under the terminated Alnylam- Ionis License on substantially the same terms and conditions as those set forth in the Alnylam-Ionis  License, as amended by Section 0 of this Letter Agreement. Effective during the period beginning on the  Alnylam-Ionis License Termination Date and ending on (a) the date that Sanofi provides the Option  Declination Notice (if Sanofi declines the License Option) or (b) the date of execution of the New License  Agreement (if Sanofi elects the License Option) (such period, the “Interim Period”), the Licensors shall  automatically grant, and hereby do grant, to Sanofi a temporary continuation of the rights that Sanofi had  as sublicensee of the Licensed IP (as defined in the Alnylam-Ionis License) under the Amended Sanofi- Regulus License prior to termination of the Alnylam-Ionis License (such                                                         ***Confidential Treatment Requested                                                                                         





 






     rights, the “Temporary License”). Notwithstanding anything herein to the contrary, under both the   New License Agreement and the Temporary License, (i) the scope and territory of the license granted   to Sanofi shall be the same as that granted to Sanofi pursuant to the Amended Sanofi-Regulus License,   (ii) the financial terms shall be as set forth in Section 0 of this Letter Agreement and (iii) the Licensors  shall not have any obligations that are greater than or inconsistent with the obligations of the Licensors   under the Alnylam-Ionis License.       Financial Terms of Sublicense, New License Agreement and Temporary License.  With respect to Net   Sales (as defined in the Sanofi-Regulus License) of Mir-21 Products that are Royalty-Bearing Products  (as defined in the Alnylam-Ionis License), whether pursuant to the sublicense under the Licensed IP  (as defined in the Alnylam-Ionis License) granted by Regulus to Sanofi pursuant to the Amended  Sanofi-Regulus License or the license under the Licensed IP granted by the Licensors to Sanofi  pursuant to any New License Agreement or Temporary License (as applicable), Sanofi shall (i)  directly pay Alnylama royalty of [...***...]% of Net Sales of such Royalty-Bearing Products during   the relevant Royalty Term (as defined below) and (ii) directly pay Ionis a royalty of [...***...]% of   Net Sales of such Royalty-Bearing Products during the relevant Royalty Term (as defined below).  For   clarity, the Licensors agree that the royalty payable by Sanofi to each Licensor with respect to Mir-21   Products that are Royalty-Bearing Products (whether pursuant to the sublicense under the Licensed IP   granted by Regulus to Sanofi pursuant to the Amended Sanofi-Regulus License or the license under   the Licensed IP granted by the Licensors to Sanofi pursuant to any New License Agreement or   Temporary License, as applicable), shall be calculated based on Net Sales as such term is defined in   Appendix 1 to the Sanofi-Regulus License (and not based on Net Sales as such term is defined in the   Alnylam-Ionis License).  Sanofi agrees that the royalty described in this Section 0 is payable to each   Licensor, regardless of whether a particular Mir-21 Product that is a Royalty-Bearing Product is   covered by such Licensor’s Licensed IP.  The Licensors hereby agree that, notwithstanding any   provision of the Alnylam-Ionis License to the contrary, and except for the royalty set forth above in   this Section 0, neither Regulus nor Sanofi shall have any royalty, sublicense income or other payment   obligations to the Licensors with respect to the Development, Manufacture or Commercialization of   Mir-21 Compounds and Mir-21 Products, including, without limitation, with respect to any payment   paid or payable by Sanofi to Regulus pursuant to the Amended Sanofi-Regulus License.  Sanofi agrees   to be bound by Section 8 of the Alnylam-Ionis License, mutatis mutandis, with respect to its royalty   payment obligations under this Section 0.  The Licensors will not be required to share any such   royalties with Regulus.         Royalties under this Section 0 will be payable with respect to a Mir-21 Product that is a  Royalty-Bearing Product on a Royalty-Bearing Product-by-Royalty-Bearing Product and country-by-  country basis from the First Commercial Sale (as defined in the Amended Sanofi-Regulus License) of   a Mir-21 Product that is a Royalty-Bearing Product in a country until the date that is the latest of   (a) the time during which the applicable Regulatory Authority in such country is not permitted to grant   Regulatory Approval for a generic equivalent of such Royalty-Bearing Product, and (b) the expiration   of the last to expire Valid Claim (as defined in the Alnylam-Ionis License) within the Regulus Patents  (as defined below) that Cover (as defined in the Alnylam-Ionis License) (i) the Manufacture (as   defined in the Alnylam-Ionis License) of such Royalty-Bearing Product in such country or (ii) the use,   sale or other Commercialization (as defined in the Alnylam-Ionis License) of such Royalty-Bearing   Product in such country (such period, the “Royalty Term”).  For purposes of this Section 0, “Regulus  Patents” shall mean, collectively: (A) the Patent Rights (as defined in the Alnylam-Ionis License)  included in, as applicable, (1) the Licensed IP sublicensed by                                                      ***Confidential Treatment Requested                                                                                      





 






     Regulus to Sanofi pursuant to the Amended Sanofi-Regulus License or (2) the Licensed IP licensed  by the Licensors to Sanofi pursuant to any New License Agreement or Temporary License (as  applicable); and (B) any other Regulus Patents (as defined in the Sanofi-Regulus License), which,  for clarity and solely for purposes of this Section 0, shall include the Mir-21 Product Specific Patents  (as defined in the Amended Sanofi-Regulus License).     Interpretation under Sanofi Ionis Agreement.  Notwithstanding the Amended Sanofi-Regulus   License, Ionis and Sanofi hereby agree that any Oligonucleotide, as such term is defined under that   certain License Agreement dated June 27, 2014 between Ionis and Sanofi-Aventis Deutschland  GmbH, a wholly owned subsidiary of Sanofi, (such License Agreement the “Sanofi-Ionis   Agreement”), that, prior to the Amended Sanofi-Regulus License, was deemed to be a Third Party- Oligonucleotide under the Sanofi-Ionis Agreement, shall continue to be deemed Third Party-  Oligonucleotides for purposes of the Sanofi-Ionis Agreement.    Assignment of Alnylam-Ionis License. Each Licensor agrees that if it assigns its rights under the   Alnylam-Ionis License, or any of the intellectual property licensed to Regulus thereunder, such   Licensor shall cause the applicable assignee to be bound by the terms of this Letter Agreement   applicable to such Licensor.

LICENSOR, and SANOFI shall be individually referred to as a “Party” and  collectively as the “Parties.”                                     RECITALS                WHEREAS, Regulus Therapeutics Inc., a company duly organized and existing  under the laws of the State of Delaware (“REGULUS”) has licensed from LICENSOR  certain patents and other intellectual propery rights under a license agreement entered into  by and between REGULUS and LICENSOR      executed as of [____________] (the  “Regulus License Agreement”); and         WHEREAS, On February 4, 2014, Regulus entered into that certain Second  Amended and Restated Collaboration and License Agreement (the “Sanofi-Regulus  License”) with SANOFI, pursuant to which, among other things, Regulus assumed  responsibility for all activities under each POC Program Plan (other than SANOFI Program  Activities) through the Achievement of Proof of Concept (each as defined in the SANOFI- Regulus License).  Regulus has now suspended the Mir-21 Fibrosis POC Program and has  requested that SANOFI amend, and SANOFI has agreed to amend, the Sanofi-Regulus  License as it pertains to the Mir-21 POC Programs, Mir-21 Compounds and Mir-21  Products, to provide for, among other things: (a) SANOFI to take responsibility for the  obligations of Regulus under the Sanofi-Regulus License with respect to the Mir-21  Fibrosis POC Program, Mir-21 Compounds and Mir-21 Products, including the  administration and expense of clinical trials related to the Mir-21 Fibrosis POC Program  (each as defined in the Sanofi-Regulus License); and (b) the license and sublicense granted  by Regulus to SANOFI with respect to Mir-21 Compounds.                                                                                 





 






         As a condition to entering into the First Amendment to the Sanofi-Regulus License  (the “First Amendment”), SANOFI requests that Licensors execute this letter agreement  (this “Letter Agreement”) where indicated below, memorializing their agreement to the  following:                                      NOW THEREFORE, in consideration of the mutual covenants herein contained  and other good and valuable consideration, the receipt and sufficiency of which is hereby  acknowledged, the Parties agree as follows:          1.

                                        EXHIBIT E                                    Form of Press Release                                   Regulus Announces Successful Restructuring of Sanofi Collaboration                  Sanofi Will Assume Development of RG-012 for Alport syndrome  LA JOLLA, Calif., November     [], 2018 – Regulus Therapeutics Inc. (Nasdaq: RGLS), a  biopharmaceutical company focused on the discovery and development of innovative medicines targeting  microRNAs, today announced that it has amended and restructured its Collaboration and License  Agreement with Sanofi (the “Amendment”).  Under the terms of the Amendment, Regulus has granted  Sanofi a worldwide exclusive license to develop and commercialize its investigational drug, targeting  miR-21 for all indications, including Alport syndrome. Under the Amendment, Sanofi will assume all  future costs and development activities associated with the advancement of RG-012, currently in Phase II  for Alport syndrome.     Under the terms of the Amendment, Regulus is eligible to receive approximately $7 million in upfront  and material transfer payments.  Regulus is also eligible to receive up to $40 million in development  milestone payments.  In addition, Sanofi will reimburse Regulus for certain out-of-pocket transition  activities and assume Regulus’ upstream license royalty obligations.      “We are pleased with Sanofi’s election to assume ongoing and future development of the RG-012  program in order to apply their expertise in rare diseases and to bring it forward as a potential new therapy  for patients with Alport syndrome.” said Jay Hagan, President and Chief Executive Officer of Regulus.  “We look forward to a rapid transition of the program to Sanofi and their ongoing clinical development,  while we continue to focus on our stated near-term objectives.  Specifically, we believe this restructuring  will improve our net cash position, yielding near term cash proceeds, eliminating RG-012-related spend  over the next several years, and will enable us to focus our resources on our other promising programs  targeting significant unmet medical needs in Autosomal Dominant Polycystic Kidney Disease and  Hepatitis B virus.”   About Alport Syndrome   Alport syndrome is an inherited form of kidney disease caused by mutations in the type IV collagen genes  (Col4A3, Col4A4 and Col4A5). Type IV collagen is important for maintaining the integrity of the  glomerular basement membrane (GBM), a vital component in the kidney structure and filtration process.  The genetic mutation in the collagen gene results in thickening in the GBM and impairment of glomerular  filtration. Alport syndrome patients experience a progressive loss of kidney function, which ultimately  leads to end stage renal disease requiring dialysis or kidney transplantation, or may even lead to death.  Alport syndrome can also cause hearing loss and eye abnormalities during late childhood or early  adolescence.  ACE (angiotensin-converting enzyme) inhibitors, although not approved for the indication,  are emerging as standard of care in patients with Alport syndrome to treat proteinuria, or abnormal  amounts of protein in the urine, an indicator of chronic kidney disease.  Alport syndrome represents a  high unmet medical need with no approved therapy.  miR-21 is believed to play a role in the disease

The role of miR-21 has been validated through  genetic knock-out models and anti-miRs targeting miR-21 have reduced the severity of fibrosis  in two distinct preclinical rodent models.     About RG-012   RG-012 is an investigational, single stranded, chemically modified oligonucleotide that binds to  and inhibits the function of miR-21 for the treatment of Alport syndrome. In preclinical studies,  RG-012 has demonstrated potent inhibition of miR-21 in vitro and in vivo, a decrease in the rate  of progression of renal fibrosis, an increase in the lifespan of the Col4A3 deficient mice by up to  fifty percent.  In May 2017, Regulus completed a Phase I multiple-ascending dose, or MAD,  study in 24 healthy volunteers (six-week repeat dosing) to determine safety, tolerability and PK  of RG-012 prior to chronic dosing in patients. In Phase I clinical studies to date there were no  serious adverse events, or SAEs, reported. Preliminary data from the first patients through a renal  biopsy study followed by an open-label extension were encouraging, with kidney tissue  concentrations achieved that would be predictive of therapeutic benefit based on animal disease  models. In addition, modulation of the target, miR-21, was observed. RG-012 has received  orphan designation in both the U.S. and Europe.    About Regulus    Regulus Therapeutics Inc.
