If Radius indicates that it wishes to Develop Combination Product, Radius shall have prior written approval of Eisai which shall not be unreasonably withheld.  The license under this Article 2.1 includes the right to grant sublicenses (without the right of such sublicensees to grant further sublicenses); provided that: (a) with respect to any sublicensee (excluding any contract research organization, contract manufacturer or other contractor of Radius granted rights solely for use on behalf of Radius) of the rights to research, Develop, have Developed, make, have made, use, promote, market, distribute, offer for sale, sell, have sold, import, export or otherwise commercialize the Product, Radius shall have prior written approval of Eisai before granting such sublicense which approval shall not be unreasonably withheld, or delayed with such determination being made with reference to the following criteria with respect to the sublicensee: (1) whether such sublicensee has the financial resources to assume the obligations of Radius with respect to the rights that are the subject of the sublicense; and (2) whether such sublicensee has personnel with skill and experience adequate to perform the obligations of Radius that are the subject of the sublicense.  It is understood and agreed that Eisai may withhold such approval if (a) such sublicensee has any material and active litigations with Eisai; or (b) such sublicensee is a Japanese pharmaceutical company.  Eisai shall have [*] ([*]) business days to notify Radius whether it is granting or withholding its approval after Radius submits the identity of the proposed sublicensee and a summary of the material terms of the proposed sublicense agreement to Eisai, and if Eisai does not provide such notice within such [*]-business day period, Eisai shall be deemed to have granted its approval; (b) Radius obtains each sublicensee’s written agreement to be subject to the same obligations as is Radius under the relevant terms of this Agreement (including Articles 6.1, 8.5, 9.5 and 11.1); (c) Radius shall remain responsible for the performance of all of its obligations under this Agreement, whether such obligations are performed

For purposes of offering Eisai the right of first negotiation, Radius will provide Eisai with written notice.  Eisai shall within [*] ([*]) days from its receipt of such written notice notify Radius, in writing, whether it will exercise the right of first negotiation.  If Eisai indicates that it wishes to exercise such right, then the parties shall promptly engage in good faith negotiation of terms for a license agreement for Asian countries.  If the parties cannot negotiate mutually acceptable terms for an agreement within [*] ([*]) days following Eisai’s notice, and the parties are not willing to extend the period for negotiation, then Eisai’s right shall expire with respect to such opportunity and Radius may negotiate with a third party concerning such opportunity; provided, however, that any such agreement shall contain terms that are in the aggregate no less favorable to Radius than those last offered to Eisai.  No license is granted with respect to activities of Radius outside of the purposes as expressly provided in this Article 2.1.  Radius shall provide to Eisai a fully signed copy of all sublicense agreements, within [*] ([*]) days of executing the same.

such inconsistency.  Radius shall have [*] ([*]) days to deliver to Eisai a plan for remediation of such inconsistency as rapidly as practicable.  Following delivery of such plan, Radius shall use commercially reasonable efforts to carry out the plan and cure the inconsistency.  If Radius fails to deliver a plan for remediation within the [*]-day period, or (ii) Radius fails to carry out the corrective plan or actions in accordance with such plan, Eisai may terminate this Agreement pursuant to Article 7.3.

 

3.5           Radius shall give a written report to Eisai on a quarterly basis with respect to the progress on the pre-clinical and clinical portions of the Development of Products in the Territory from the Effective Date.  If Eisai notifies Radius of its intent to Develop Products in Japan, within [*] ([*]) days of the date of the notice, the Parties will establish a Joint Steering Committee (the “SC”) to review progress on the pre-clinical and clinical portions of the Product Development contemplated by this Agreement. The purpose of the SC is to facilitate the exchange of information and the coordination between the Parties relating to the Development of Products, and to serve as a forum for Radius to keep Eisai updated with regard to the Development of Products in the Territory and Eisai to keep Radius updated with regard to the Development of Products in Japan (in the form of summaries of the Development plan, clinical design and strategy, etc.).  The SC will be composed of two representatives of each Party, who shall be appointed (and may be replaced at any time) by such Party on written notice to the other in accordance with this Agreement.  The SC will meet at least twice per year, or at any other frequency agreed by the SC.  The first meeting of the SC shall be held within [*] ([*]) days after establishing the SC.  Meetings may be held by telephone or video conference.  Minutes of all meetings of the SC shall be prepared by Radius within [*] ([*]) days after each meeting.

 

3.6           The quorum for SC meetings shall be two (2) members, provided there is at least one member from each of Eisai and Radius is present.  The SC will render decisions by unanimous vote.  Disagreements among the SC regarding the Program will be resolved via good-faith discussions; provided, that in the

Radius shall permit independent certified public accountants selected by Eisai and reasonably acceptable to Radius to examine such books and records upon reasonable notice during normal working hours, for the purpose of verifying the reports, accountings and payments hereunder. Such examination right shall not be exercised more than once in any calendar year nor more than once in respect to any given payment period.  Eisai agrees to hold in confidence all information concerning royalty payments and reports, and all information learned in the course of any audit or inspection, except to the extent necessary for Eisai to reveal such information in order to enforce its rights under this Agreement or if disclosure is required by law, regulation or judicial order. Such independent accountants shall agree in writing with Eisai to treat all records reviewed in the course of the audit or inspection as the confidential information of Radius and shall not disclose to Eisai any other data or other confidential information of Radius.  The opinion of such independent accountants regarding such reports, accountings and payments shall be binding on the Parties hereto.  The fees and expenses of the independent accountants shall

be paid by Eisai, except that if the opinion of the independent accountants shows that less than [*] ([*]) percent of the amounts of the royalties due to Eisai has been reported and paid, or that Supply Price of bulk Compound or the Semi-Product is substantially different from Radius’ actual Production Cost plus [*] ([*]) percent, such fees and expenses shall be paid by Radius.

 

4.5           All royalties shall be paid by wire transfer of funds to an account at Eisai’s designated bank in Tokyo, and shall be paid in US dollars.

 

4.6           Except for income taxes that may be assessed against Eisai, all payments by Radius to Eisai under Articles 4.1-4.3 of this Agreement shall be made without deduction for or on account of any tax or all tax.  All taxes in respect of payments under this Agreement shall be for the account of Radius, and will be borne and paid by Radius prior to the date on which penalties apply.  If Radius is compelled by law to make payment subject to any tax and Eisai does not actually receive on the due date a net amount equal to the full amount provided under this Agreement, Radius shall pay all necessary additional amounts to ensure receipt by Radius of the full amount so provided for under Articles 4.1-4.3, as applicable. The Parties will cooperate to minimize, to the extent legally permissible, the tax liabilities related to this Agreement.  Notwithstanding the foregoing, such cooperation shall not cause any adverse tax consequences to be incurred by either Party which would not have been incurred under the provisions of this Agreement, including this Article 4.6.

The Prosecuting Party shall provide the 

 

21











 

other Party with a copy of all material communications from any patent authority in the applicable jurisdictions regarding the Joint Patent being prosecuted by such Party, and shall provide drafts of any material filings or responses to be made to such patent authorities a reasonable amount of time in advance of submitting such filings or responses.  In particular, each Prosecuting Party agrees to provide the other Party with all information necessary or desirable to enable the other Party to comply with the duty of candor/duty of disclosure requirements of any patent authority.  Neither Party shall grant any third party(ies) the right to practice the Joint Patents or any Joint Inventions without prior consent of the other Party anywhere in the world.  Any royalty from such third parties shall be distributed to the Parties and each Party is entitled to obtain no less than [*] ([*]) percent of such royalty.  Either Party may determine that it is no longer interested in supporting the continued prosecution or maintenance of a particular Joint Patent in a country or jurisdiction, in which case:  (i) such Party shall, if requested in writing by the other Party, assign its ownership interest in such Joint Patent in such country or jurisdiction to the other Party for no additional consideration, and (ii) if such assignment is so effected, any such Joint Patent would thereafter be deemed a Radius Patent in the case of assignment to Radius, or a Eisai Patent in the case of assignment to Eisai.

 

6.10         The Parties will discuss and recommend for which, if any, of the patents within the Eisai Patents, Radius Patents and Joint Patents in the world the Parties should seek patent term extensions in the world.  Radius in the case of the Radius Patents, and Eisai in the case of the Eisai Patents, shall have the final decision-making authority with respect to applying for any such patent term extensions in the world, and will act with reasonable promptness in light of the development stage of Products to apply for any such patent term extensions.  If in a particular country or jurisdiction in the world only one such patent can obtain a patent term extension, then the Parties will consult in good faith to determine which such patent should be the subject of efforts to obtain a patent term extension.  The Party that does not apply for an extension hereunder will cooperate fully with the other Party in making such filings or actions, for

example and without limitation, making available all required regulatory data and information and executing any required authorizations to apply for such patent term extension.

 

6.11         In the event that a third party sues either Party, its Affiliates, licensees or sublicensees for patent infringement involving the manufacture, use, sale, distribution or marketing of Product anywhere in the world, the Party sued shall promptly notify the other Party with regard to such action.  With respect to the defense of any such action in the Territory, the Party sued shall be wholly responsible for the defense of such action and shall bear all costs and expenses associated therewith.  In any event, the Party sued shall have the right to request, solely at its own expense, the other Party to assist and cooperate in connection with the defense of such suit.  Upon such request, the other Party shall use all reasonable efforts to assist and cooperate in connection with the defense of such suit.

 

6.12         In the event that either Party becomes aware of actual or threatened infringement of Eisai Patents, Radius Patents or Joint Patents anywhere in the world, it shall promptly notify the other Party thereof in writing, which such notice shall include all information available to the notifying Party regarding such alleged infringement. With respect to infringement of Eisai Patents anywhere in the world, Eisai shall have the first right (but not the obligation) to pursue any and all injunctive, compensatory and other remedies (collectively, “Remedies”) against the infringing third party.  Eisai shall have a period of [*] ([*]) days after delivery to it of such notice and information to elect to so enforce such Eisai Patents.  In the event Eisai does not so elect, it shall so notify Radius in writing within such [*]-day period, and Radius shall have the right to commence a suit or take action to enforce the applicable Eisai Patents against such infringing third party in the Territory.

23











 

defenses against Eisai with respect to the validity of the Eisai Patents, it shall provide Radius such basis in writing within such [*] ([*]) day period, in which case Radius shall not have such enforcement right in the Territory; provided that, if the Parties discuss in good faith and agree that there could have a big negative impact on the Net Sales by such infringement, Radius shall thereafter be entitled to the royalty adjustment(s) described in Article 4.3 with respect to the applicable country(ies) where such infringement exists as if no patent protection or data protection clauses are in effect for such country(ies).  The Party pursuing Remedies pursuant to this Article 6.12 in respect of Eisai Patents, Radius Patents or Joint Patents shall bear its own costs and expenses relating to such pursuit.

 

Any damages and other amounts collected in any suit or the settlement thereof  that is the subject of this Article 6.12 shall be distributed first, to the Party that pursued Remedies to cover its costs and expenses and, second, to the other Party to cover its unreimbursed costs and expenses, if any, relating to the pursuit of such Remedies.  The balance, if any remaining after the Parties have been compensated for expenses shall be distributed: (a) to Radius in an amount equal to its lost profits or a reasonable royalty on the sales of the infringer with respect to activity in the Territory (whichever measure the court or settlement agreement uses to determine damages); and (b) to Eisai in an amount equal to its lost profits or a reasonable royalty on the sales of the infringer with respect to activity in Japan (whichever measure the court or settlement agreement uses to determine damages). The balance, if any, remaining after Radius has been compensated for lost profits or lost sales and Eisai has been compensated for lost royalties with respect to infringement in the Territory and Eisai has been compensated for lost profits or lost sales in Japan shall be distributed:  (i) [*] ([*]) percent to Radius and [*] ([*]) percent to Eisai in case of Radius pursuing Remedies, and (ii) [*] ([*]) percent to Eisai and [*] ([*]) percent to Radius in case of Eisai pursuing Remedies.

 

With respect to infringement of Radius Patents anywhere in the world, Radius shall have the first right (but not the obligation) to pursue any and all

24











 

Remedies against the infringing third party.  Radius shall have a period of [*] ([*]) days after delivery to it of such notice and information to elect to so enforce such Radius Patents.  In the event Radius does not so elect, it shall so notify Eisai in writing within such [*]-day period, and Eisai shall have the right to commence a suit or take action to enforce the applicable Radius Patents against such infringing third party in Japan.  In the event Radius has a reasonable business basis not to enforce such Radius Patents in Japan, with the determination of reasonableness taking into account the costs of such litigation, its likelihood for success, the potential damages or settlement recovery, and the potential for exposure to counterclaims and defenses against Radius with respect to the validity of the Radius Patents, it shall provide Eisai such basis in writing within such [*] ([*]) day period, in which case Eisai shall not have such enforcement right in Japan.

 

In the event that a third party infringes any Joint Patents, Radius shall have the first right (but not the obligation) to pursue Remedies against the infringing third party if such infringement is conducted in the Territory, and Eisai shall have the first right (but not the obligation) to pursue Remedies against the infringing third party if such infringement is conducted in Japan.

 

In any event as set forth in this Article 6.12, upon request from the other Party, Eisai and Radius shall assist one another and cooperate in the pursuit of Remedies, including without limitation joining such action as a party plaintiff if required by applicable law to pursue such action, without charge to the other Party for costs and expenses incurred thereby.

 

6.13         The Parties shall keep one another informed of the status of and of their respective activities regarding any litigation or settlement thereof concerning the Product.  Neither Party shall enter into any settlement or consent judgment or other voluntary final disposition of any suit defended or action brought pursuant to Article 6.12 without the other Party’s prior written consent, which consent shall not be unreasonably withheld.

TERM AND TERMINATION

 

7.1           The term of this Agreement shall be determined on a country by country basis, and for each country shall come in effect on the Effective Date and, unless earlier terminated hereunder, shall terminate upon the later of:  (a) the [*] ([*]) anniversary of date of commercial launch of the Product in that country, or (b) the last remaining Valid Claim in Eisai Patents expires, lapses or is invalidated in that country, the Product is not covered by data protection clauses, and the sales of lawful generic version of the Product account for [*] percent ([*]%) or more of the total sales of all pharmaceutical products containing Compound (including the Product) in that country.  Provided the license to Radius has not previously been terminated under this Agreement, upon expiration of the royalty obligations as to any Product in any country in the Territory, Radius shall thereafter have in perpetuity a fully paid up, royalty-free, non-exclusive license in that country to use the Eisai Know-how to use, market and sell that Product in such country without any accounting to Eisai.

 

7.2           This Agreement can be terminated by Radius, upon [*] ([*]) days’ prior written notice to Eisai, as a whole in the Territory, based on a reasonable determination, using the same standards Radius would use in assessing whether or not to continue development and marketing of a product of its own making or to which it had similar rights, that the medical/scientific, technical, regulatory or commercial profile of the Product does not justify continued development or marketing of the Product.  Otherwise, neither Party has any right to terminate without the other Party’s consent except as specified in this Article 7.

 

7.3           This Agreement can be terminated by Eisai on a country by country basis at any time prior to the date on which Radius has filed for either a FDA NDA approval or a EMEA marketing approval with respect to a Product, upon [*] ([*]) days’ prior written notice to Radius in the event that Radius is not using its commercially reasonable efforts to Develop the Product in the Territory, unless such default is cured within such [*]-day period (or, if such breach is not

26











 

capable of being cured within such [*]-day period, within such amount of time as may be reasonably necessary to cure such breach, so long as Radius is making diligent efforts to do so.  Any termination pursuant to this Article 7.3 shall be based on Eisai’s good faith determination that Radius has not used its commercially reasonable efforts to Develop the Product in the Territory having reference to prevailing principles and time scales associated with the Development, clinical testing and government approval of products of a like nature to such Products.

 

7.4           If either Party fails to perform, in any material respect, covenants or provisions of this Agreement and if such default is not corrected within [*] ([*]) days after receiving written notice from the other Party with respect to such default, such other Party shall have the right to terminate this Agreement by giving written notice to the other Party in default.  There shall be no waiver of default or impairment of the right to give notice implied by failure to give notice in any period.

 

7.5           If, at any time, either Party shall file in any court or agency pursuant to any statute or regulation of any state or country, a petition in bankruptcy or insolvency or for reorganization or for an arrangement or for the appointment of receiver or trustee of the Party or of its assets, or if either Party proposes a written agreement of composition or extension of its debts, or if either Party shall be served with an involuntary petition against it, filed in any insolvency proceeding, and such petition shall not be dismissed within [*] ([*]) days after the filing thereof, or if either Party shall propose or be a Party to any dissolution or liquidation, or if either Party shall make an assignment for the benefit of creditors, the other Party may terminate this Agreement.

 

7.6           Radius shall notify Eisai in advance if Radius proposes to be acquired by or to transfer all of its pharmaceutical business assets (or an essential part of such assets) or [*] ([*]) percent or more of its voting stock to any third party person or organization, or to otherwise come under the control of, such a person or organization, whether resulting from merger, acquisition, consolidation or

27











 

otherwise.  Eisai shall have [*] ([*]) business days following the receipt of such notice from Radius to notify Radius whether Eisai will deem the proposed change a termination event based on the criteria listed in items (1)-(3) below as well as the criteria listed in items (a)-(b) below and if Eisai does not provide such notice within such [*] business day period it will be deemed to have agreed that such change will not entitle Eisai to seek termination under this Article 7.6.  In the event that Radius gives such prior notice and is notified by Eisai that Eisai will deem the proposed change a termination event or Radius without giving such prior notice is acquired by or transfers all of its pharmaceutical business assets or an essential part of such assets to, or if [*] ([*]) percent or more of its voting stock is acquired by, or otherwise comes under the control of, a person or an organization, whether resulting from merger, acquisition, consolidation or otherwise, Radius shall promptly notify Eisai of such change and Eisai shall have the right to terminate this Agreement with notice to Radius delivered within [*] ([*]) days of the occurrence of such change in the event that Eisai reasonably determines that the person or organization assuming control of Radius is not able to perform this Agreement with the same degree of skill and diligence that Radius shall use, such determination being made with reference to the following criteria with respect to the person or organization assuming control of Radius: (1) whether such person or organization has the financial resources to assume the obligations of Radius with respect to Development and commercialization of Products; (2) whether such person or organization has personnel with skill and experience adequate to assume the obligations of Radius with respect to Development and commercialization of Products at the stage of Development and commercialization as of the date of such change; and (3) whether such person or organization expressly assumes all obligations imposed on Radius by this Agreement in writing and agrees to dedicate personnel and financial resources to the Development and commercialization of the Product that are at least as great as those provided by Radius.  Radius shall give Eisai information by which Eisai can reasonably determine whether such person or organization satisfies the above criteria together with the notice of such change.  It is understood and agreed that notwithstanding the above criteria listed in (1)-(3),

28











 

Eisai shall have the right to terminate under this Article 7.6 if: (a) such person or organization has any material and active litigations with Eisai; (b) such person or organization is a [*] pharmaceutical company; or (c) such person or organization is a hostile takeover bidder against Radius which has not been approved by the Board of Directors of Radius as constituted immediately prior to such change of control.  It is understood and agreed that an underwritten public offering of Radius’ common stock pursuant to a Registration Statement on Form S-1 under the Securities Act of 1933, as amended, will not be considered a change of control triggering a termination right under this Article 7.6.

 

ARTICLE 8

 

RIGHTS AND DUTIES UPON TERMINATION

 

8.1           Upon termination of this Agreement, Eisai shall have the right to retain any sums already paid by Radius hereunder, and Radius shall continue to be obligated to pay all sums accrued hereunder at the time of termination which are then due.

 

8.2           Upon termination of this Agreement for any reason except material breach by Eisai, Radius shall notify Eisai of the amount of Product Radius then have on hand, the sale of which would, but for termination, be subject to royalty, and Radius shall thereupon be permitted to sell that amount of Product provided that Radius shall pay the royalty thereon at the time herein provided for.

 

8.3           In either case that Radius terminates this Agreement in accordance with Article 7.2 or that Eisai terminates this Agreement in accordance with Article 7.3, 7.4, 7.5 or 7.6, Radius shall provide or transfer to Eisai all technical information and know-how categorized as Radius Know-How which it possesses at the time of the termination in a timely manner.  Thereafter, Eisai shall have a worldwide, royalty-free and perpetual license, under Radius Patents and Radius Know-How, to develop, manufacture, have manufactured, import and sell Compound and Product.  In addition to the license to Radius

(vi)          is required by law, regulation or court order to be disclosed; provided that receiving Party agrees to provide providing Party with prompt notice of such request so that providing Party will have an opportunity to limit obtain appropriate protective order regarding such disclosure.

32











 

disclosure.  The portion of such information that remains publicly undisclosed after such disclosure shall not be used for other than this Agreement and shall be treated in confidence.

 

Any confidential information disclosed by each Party hereunder may be used only by employees of the other Party or its affiliates who agree to be bound by a confidentiality obligation hereunder and who have a genuine need to know such information for the purposes permitted by this Agreement.  The Parties shall take reasonable measures to assure that no unauthorized use or disclosure is made by others to whom access to such confidential information is granted.

Notwithstanding anything to the contrary herein, either Party may publish information about the clinical trials performed or to be performed on the Product without the need to obtain the other Party’s approval (provided, however, that such Party will use reasonable efforts to inform the other Party and to allow the other Party to comment on the disclosure), to the extent that such disclosure is required, in the disclosing Party’s reasonable opinion, to comply with applicable laws, regulations, guidelines and/or formal position papers of recognized pharmaceutical industry associations or medical journals 

 

34











 

or such Party’s standard business practice with respect to similar disclosure of clinical trial information.

1.             EXECUTIVE SUMMARY

 

ER-306323 is a selective estrogen receptor modulator (SERM) that was originally discovered by Eisai Co., Ltd. Radius plans to develop ER-306323 for the treatment of vasomotor symptoms associated with menopause, and for the treatment and prevention of osteoporosis in postmenopausal women at risk of fracture.

 

This development plan for ER-306323 is premised upon a strategy of demonstrating a substantial improvement in tolerability over Evista® (raloxifene; Eli Lilly and Company) and other SERM’s that are currently in clinical development for the treatment of patients with osteoporosis (e.g. bazedoxifene; Wyeth Pharmaceuticals Inc.). While effective for osteoporosis, Evista induces hot flashes in many post-menopausal women which is a significant deterrent to adoption. In contrast, ER-306323 has the potential (based on a pre-clinical model) to be developed and marketed for the relief of vasomotor symptoms associated with menopause, allowing a clear differentiation over currently available SERM’s and a faster development path to commercialization than is possible with the traditional osteoporosis indication.

 

Pre-clinical data suggest that ER-306323 is an agonist on [*], with comparable efficacy to [*]. Also, [*], ER-306323 is an antagonist on the [*] and [*]. However, ER-306323 is an agonist on the [*]. Accordingly, the preclinical data support the strategy for developing this compound as an advance over currently available SERM’s for the relief of vasomotor symptoms, as well as for the treatment and prevention of osteoporosis.

 

2.             CORE CLINICAL DEVELOPMENT PLAN FOR ER-306323

 

The following is an outline Target Product Profile (TPP) for ER-306323. The clinical development plan is based on the expected clinical benefit and first indication of alleviation of moderate and severe vasomotor symptoms in postmenopausal women since this represents an unmet need and the most efficient path to the market, and on the second indication of prevention of continuing bone loss in the postmenopausal women at risk of osteoporosis. Not only does ER-306323’s activity on vasomotor symptoms allow for a clear differentiation over currently available SERM’s, but it also enables a faster development path than is possible with the osteoporosis prevention indication.

By enrolling women with moderate to severe vasomotor symptoms, the Phase lb study of ER-306323 will develop data on the efficacy of ER-306323 for the alleviation of hot flashes in the index population. These data will constitute Proof of Concept for the product in this indication and provide the basis for the clinical and statistical planning for Phase 2 and Phase 3 studies.

 

This study will also collect full pharmacokinetics data on Days [*] and [*] and trough samples on other study days. Pharmacodynamic markers will include frequency of hot flash events, and markers of estrogen effect such as serum gonadotropins and serum lipids.

 

The Phase lb study will also collect preliminary information on [*] and [*]l safety of ER-306323 and will collect preliminary information on the potential benefits of ER-306323 for prevention of osteoporosis in this population through the pharmacodynamics effect of ER-306323 on biochemical markers of bone resorption and accretion such as [*].

 

2.2                               Phase 2 Clinical Program

 

The Phase 2 study will be a statistically powered dose-ranging program to identify the most effective dose of ER-306323 to take into Phase 3 development. The Phase 2 program will provide statistical and clinical proof of efficacy for ER-306323 in the alleviation of moderate and severe vasomotor symptoms in postmenopausal women. In addition, the Phase 2 study will provide early evidence of efficacy for ER-306323 in the indication of prevention of postmenopausal osteoporosis through the assessment of bone marker and bone mineral density.

Finally, the Phase 2 program will provide preliminary evidence of endometrial safety for ER-306323.

 

Phase 2 Study Objectives:

 

The objectives of this study are therefore as follows:

 

·                  To provide a clinical and statistical basis for the selection of the optimal dose of ER-306323 to be taken forward into final development

 

·                  To demonstrate proof of efficacy of ER-306323 for reduction in frequency and severity of hot flashes in postmenopausal women.

 

·                  To determine the pharmacodynamic. effects (i.e., effects on mineral metabolism and biochemical markers of bone formation and resorption) of [*] months of treatment with ER-306323.

 

·                  To determine the effects of [*] months of treatment with ER-306323 on BMD.

 

·                  To determine the overall safety and tolerability of ER-306323 after [*] months of dosing in postmenopausal women with vasomotor symptoms.

 

·                  To determine the uterine safety of ER-306323 after [*]months of dosing in postmenopausal women with vasomotor symptoms.

 

Study Design

 

The Phase 2 study will be a randomized, double-blind, multicenter, placebo-controlled trial covering 1 [*] of observation, followed by randomization of qualified subjects to [*] months of treatment and a 1 [*] safety follow-up period.

 

Patients will be postmenopausal women defined as having [*] months of spontaneous amenorrhea, or [*] months of spontaneous amenorrhea with serum FSH levels of > 40 IU/L, or as women who are [*]-weeks post-surgical oophorectomy.

 

Moderate hot flashes are defined as a sensation of heat with flushing but as not being incapacitating, while severe hot flashes are defined as the same but with the element of incapacitation in that the subject must stop current activity. To ensure adequate evidence of therapeutic effect is available, study participants will be required to have frequent hot flashes defined as [*] hot flashes per [*] or [*] to [*] hot flashes per [*]. During the period of observation, patient will document hot flash frequency and severity to prospectively ensure qualification on that criterion. Efficacy will be assessed as the reduction in frequency and severity of hot flashes compared to placebo.

 

The estimated subject number and dose groups are outlined below:

It is estimated that the Phase 2 study will require about [*] evaluable subjects to achieve its stated goals. The Phase 2 study will provide evidence of dose-dependent efficacy for ER-306323 and will also provide adequate statistical power to select the optimal dose for Phase 3. The criteria for dose selection will be based on an integration of the major efficacy and safety variables of the study.

 

In addition, the Phase 2 data will also provide statistical evidence of effect of ER-306323 on markers of bone resorption and accretion while providing preliminary evidence of effect of ER-306323 on bone density.

 

Like the Phase lb study, the Phase 2 study will continue to provide additional pharmacodynaraics effects of ER-306323 such as estrogenic effects on serum gonadotropins and serum lipids. Markers of bone effect will again be collected such as serum osteocalcin, bone procoilagen 1 carboxy-terminal propeptide (PICP), N-propeptide of Type-1 collagen (PIMP) and bone-specific alkaline phosphatase.

 

Additional safety information on cardiac (QT) safety and endometrial safety of ER-306323 will be evaluated in more detail through endometrial biopsy in a subset of patients in each treatment group. Finally, estrogenic effect. of ER-306323 on coagulation factors will also be assessed.

2.3                               Phase 3 Clinical Program

 

The Phase 3 study is designed to provide evidence of long-term endometrial safety of ER-306323. In addition, the Phase 3 study will provide additional confirmation of efficacy of ER-306323 for reduction in frequency and severity of hot flashes in women with moderate and severe postmenopausal vasomotor symptoms.

The Phase 3 trial will be a statistically-powered, double-blind, randomized, multicenter trial that will be powered on the basis of the reduction of hot flashes but which will enroll a sufficient number of women to provide adequate assessment of endometrial safety over 12 months. It is generally requested that more than one dose of the new medication be studied in the Phase 3 safety trial. As a study of endometrial safety, the Phase 3 trial will only enroll women with an intact uterus and, as a safety measure, will exclude women with any history of breast cancer or of a recent abnormal mammogram.

 

This study will also provide further evidence of the efficacy of ER-306323 on BMI), while not in the traditional population of women with documented severe osteoporosis.

 

Phase 3 Study Objectives:

 

The objectives of this study are therefore as follows:

 

·                  To provide clinical evidence of the long-term endometrial safety of ER-306323 in postmenopausal women with moderate and severe vasomotor symptoms.

 

·                  To confirm, clinically and statistically, the therapeutic benefit of ER-306323 for treatment of moderate and severe vasomotor symptoms in menopause

 

·                  To provide evidence of the long-term benefit of ER-306323 for prevention of postmenopausal osteoporosis.

 

·                  To determine the overall safety and tolerability of long-term treatment of ER-306323 in postmenopausal women with vasomotor symptoms.

 

Study Design

 

The Phase 3 study will be a randomized, double-blind, multicenter, placebo-controlled trial covering 1 [*] of observation, followed by randomization of qualified subjects to 3 months of treatment and a 1 [*] safety follow-up period. Two doses of ER 206323 will be studied.

 

Patients will be postmenopausal women defined as being 45 years old or greater and having [*] months of spontaneous amenorrhea, or [*] months of spontaneous amenorrhea with serum FSH levels of > [*] IU/L, or as women who are [*]-weeks post-surgical oophorectomy.

 

As for the Phase 2 study, hot flash frequency and severity will be established during a pretreatment period of observation and qualifying patients will be then eligible to enroll in the study.

 

As before, the criterion for entry will be a frequency of [*]hot flashes per day or [*] to [*] hot flashes per [*]. Efficacy will be assessed as the reduction in frequency and severity of hot flashes compared to placebo.

 

The estimated subject number and dose groups are outlined below:

It is estimated that the Phase 3 study will require about [*] subjects to provide adequate evidence of clinical safety for ER-306323. Since [*]doses of ER-306323 will be administered in this trial, there will be at least [*] patients available to provide endometrial safety data on this product.

 

While powered beyond this need, the Phase 3 study will provide confirmatory evidence of efficacy for ER-306323. The [*] doses to be employed in the Phase 3 trial will include the [*] as identified in the Phase 2 study as well as [*]. Efficacy will be based on difference in efficacy [*]. Endometrial safety will be based on self-reported vaginal bleeding, endometrial ultrasound and endometrial biopsy data. Endometrial biopsy data will be assessed according to objective common criteria by a panel of [*]pathologists in [*] independent medical institutions.

 

The Phase 3 study will provide additional long-term safety information on serum lipids and on coagulation markers such as [*]. Influence of ethnicity on efficacy and safety will be assessed and drug-drug interaction effects will also be evaluated where appropriate.

 

BMD will also be assessed at start and end of treatment and treatment effect will be compared to [*]. Markers of bone metabolism will also be assessed.

 

Finally, overall clinical and laboratory safety will be assessed throughout the study.

In addition to the Core Clinical Development Studies outlined above, additional studied will likely be required for approval of ER-306323 for treatment of postmenopausal vasomotor symptoms.

Drug-drug interaction studies will likely be required depending on the metabolic pathway of ER-306323. At present, drugs commonly used in this population that may require study would be digoxin, diuretics, antacids, and antihypertensives.

 

A dedicated QT interval study may also be required, in particular in the USA, since a complete package of cardiac safety is usually now a condition of approval for new clinical entities.

 

2.5                               Clinical Studies for the Osteoporosis Indication

 

The osteoporosis indication will require additional preclinical studies including [*]. It is required that this assessment be performed in [*].

 

Since the indication of prevention of bone loss requires statistical evidence of reduction in bone loss and documentation of a positive effect on fracture frequency, [*] years of exposure is needed to obtain the statistical benefit. hi addition, the population at risk for vertebral and hip fracture is women with more severe osteoporosis and, while there may be some overlap between this population and women with moderate or severe vasomotor symptoms, they are essentially distinct populations. Therefore, while the data on bone metabolism collected during the development of the vasomotor symptomatology indication may be very helpful for the further development of the osteoporosis/fracture prevention indication, additional separate statistically-powered studies would be required for registration of ER-306323 for the second indication. [*].

 

Studies to register ER-306323 for the osteoporosis indications are required to be compliant with the FDA Guideline “Guidelines for Preclinical and Clinical Evaluation of Agents used in the Prevention or Treatment of Postmenopausal Osteoporosis” issued April, 1994, and with EMEA Guidance “Note for Guidance on Postmenopausal Osteoporosis in Women” issued in January, 2001 and modified in April 2005. Both guidelines recommend the study of BMD as the primary outcome for prevention of osteoporosis but advise that data on fracture occurrence must also be provided in the final submission documents. In the case of FDA guidelines, approval for the prevention of bone loss in postmenopausal women is contingent on proof of fracture prevention or at least a trend towards fracture prevention [*]with a post-marketing commitment to continue the study until statistical confirmation of efficacy for fracture prevention is achieved. Such a requirement requires substantial number of patients to be enrolled.

 

The study population is recommended to be postmenopausal and to have a documented bone density of at least [*]standard deviation below the population norm for the study of fracture prevention. Prior studies in this indication have generally enrolled and treated about 600 — 3000 patients.

 

In the absence of a specific Phase 2 dose-finding study in this population, it is possible that FDA will request to consider two doses in the definitive Phase 3 trial. However, this remains a speculation and an item for regulatory consultation.

 

Finally, the endometrial safety study employed for the registration of the vasomotor symptomatology indication would likely be sufficient to support the long-term safety requirement of the osteoporosis prevention indication also.

2.6                               Phase 3 Clinical Program for Osteoporosis Prevention

 

The Phase 3 study is designed to provide clinical and statistical evidence of the efficacy and long-term safety of ER-306323 in the prevention of fracture and the reduction in bone loss in postmenopausal women. Therefore, an initial study period of [*] years is anticipated to meet the conditions of approvability..

 

The Phase 3 trial for fracture prevention will be a [*] trial that will be powered on the basis of fracture prevention and prevention of bone loss over the duration of exposure. While both FDA and EMEA accept comparative trials for prevention of bone loss, the

 

requirement of FDA that reduction in fracture incidence be shown suggests that only placebo-control will be acceptable. However, with approval of a related molecule in the same class which has been registered through placebo-controlled trials, a comparative trial may be negotiated.

 

The primary efficacy outcome will be prevention of bone loss as assessed by [*] and a trend toward fracture prevention as assessed [*].

 

BMD will be assessed by [*]. Subsets of patients will be also assessed using more sensitive methods of bone density measurement such as quantitative computerized tomography (qCT) and extreme CT with measures cortical and trabecular bone density in the extremities. Fracture data for all fractures, vertebral and hip fractures will be collected and analyzed collectively and separately.

 

Phase 3 Study Objectives:

 

The objectives of this study are therefore as follows:

 

·                  To provide clinical and statistical evidence of reduction in bone loss and to provide evidence of a trend towards prevention of fractures with long-term treatment with ER-306323

 

·                  To determine the overall safety and tolerability of long-term treatment of ER-306323 in postmenopausal women with osteoporosis who are at risk of fracture.

 

Study Design

 

The Phase 3 study will be a randomized, double-blind, multicenter, placebo-controlled trial consisting of [*] years of treatment with either ER-306323 or placebo.

 

Patients will be postmenopausal women defined as being 55 years old or greater and being at least [*] years postmenopausal, with serum FSH levels of > [*] 1-U/L and serum estradiol of < [*] pg/mL. Patients will have a BMD of <[*]standard deviations below the norm or <[*]standard deviations below the norm if additional risk factors of fracture are identified such as age > 65 years, maternal history of fracture, or prior documented fracture.

 

The estimated subject number and dose groups are outlined below:

It is estimated that the Phase 3 study will require about [*] subjects per treatment arm to provide adequate evidence of efficacy for fracture prevention and clinical safety for ER-306323.

 

The Phase 3 study will provide confirmatory evidence of efficacy for ER-306323 for reduction in bone loss and prevention of fracture in postmenopausal women.

 

The dose to be employed in the Phase 3 trial will be based on the results of the Phase 2 trial for menopausal symptoms and the BMD data accumulated in the Phase 2 and Phase 3 trials.

 

The Phase 3 study will provide additional long-term safety information on serum lipids and on coagulation markers such as [*]. Influence of ethnicity on efficacy and safety will be assessed and drug-drug interaction effects will also be evaluated where appropriate.

 

Finally, overall clinical and laboratory safety will be assessed throughout the study.

4.1                               General Pharmacology

 

Studies have been completed to establish the activity of ER-306323 in a [*] model [*]. In this model, ER-306323 suppresses [*], supporting the proposed application of this drug to treat vasomotor symptoms associated with menopause.

 

To establish osteoporosis efficacy studies will need to be performed to identify bone protective doses of ER-306323. This will be conducted using a [*]model of [*] osteoporosis, with a comparison to active reference agents, [*]. Endpoints for these studies will include measurement of [*] and [*], analysis of [*] using [*] and assessment of [*].

 

4.2                               Toxicology, Safety Pharmacology and ADME

 

A safety package sufficient to support an IND will need to be completed. This package will include assessment of genotoxicity, pharmacokinetics and metabolism, toxicology and safety pharmacology. To support the proposed phase I study design, we anticipate conducting a [*]-week repeat dosing toxicology study in both [*] and [*].

 

Completion of the IND supporting safety package is expected in [*].

5.                                      REGULATORY STRATEGY

 

Prior to initiation of the proposed clinical development activities for ER-306323, the United States Food and Drug Administration (FDA) will be consulted as to the appropriateness of the preclinical safety information and the early clinical activities for the ultimate development goals. On completion of the Phase 1 studies, FDA will again be consulted on the appropriateness of the Phase 2 and Phase 3 clinical development studies for the registration of ER-306323 for the postmenopausal vasomotor symptom study. At that time, the necessity for, the timing and the design of any additional studies required for registration, such as drug interaction or cardiac QT safety studies, will be discussed.

 

In addition, at the time of the pre-Phase 2 meeting with FDA, the preclinical data and Phase 1 data will be communicated with the EMEA to ensure agreement on the appropriateness of the development plan for European registration.

 

Early consultation is proposed to ensure an efficient development program and earliest possible approval. Subsequent to first formal contact with the respective agencies, issues of product quality will be addressed on an ongoing basis.

 

Based on the need to manufacture product for Preclinical and Safety studies and to complete the Quality and Preclinical information submission package, it is expected that the preIND meeting will be held in [*]and that the IND will be filed [*].
