(Date of Event Which Requires Filing of this Statement)

If the filing person has previously filed a statement on Schedule 13G to report the acquisition that is the subject of this Schedule 13D, and is filing this schedule because of §§240.13d-1(e), 240.13d-1(f) or 240.13d-1(g), check the following box. o

Note: Schedules filed in paper format shall include a signed original and five copies of the schedule, including all exhibits. See §240.13d-7 for other parties to whom copies are to be sent.

* The remainder of this cover page shall be filled out for a reporting person's initial filing on this form with respect to the subject class of securities, and for any subsequent amendment containing information which would alter disclosures provided in a prior cover page.

The information required on the remainder of this cover page shall not be deemed to be "filed" for the purpose of Section 18 of the Securities Exchange Act of 1934 ("Exchange Act") or otherwise subject to the liabilities of that section of the Act but shall be subject to all other provisions of the Act (however, see the Notes).

(1) The Reporting Person is party to certain agreements with the Separately Filing Group Members (as defined in the Existing Schedule 13D defined below), which agreements contain, among other things, certain voting agreements and limitations on the sale of the Reporting Person’s shares of Common Stock. As a result, the Reporting Person may be deemed to be a member of a “group,” within the meaning of Section 13(d)(3) of the Act (as defined in this Schedule 13D), comprised of the Reporting Person and the Separately Filing Group Members.  Shares listed as beneficially owned by the Reporting Person exclude shares held by any of the Separately Filing Group Members, in each case as to which the Reporting Person disclaims beneficial ownership.

The percentage is calculated based upon 35,002,080 shares of outstanding Common Stock being deemed issued and outstanding, which consists of: (i) 879,370 shares of Common Stock that are issued and outstanding and (ii) an aggregate of 34,122,710 shares of Common Stock issuable upon conversion of all shares of Preferred Stock outstanding as of December 31, 2013 following the issuance of the Dividend Shares (as defined in this Schedule 13D) as disclosed in the Issuer’s Quarterly Report on Form 10-Q, filed with the SEC on November 14, 2013, and as disclosed to the Reporting Person by the Issuer separately.  Because shares of Preferred Stock vote together with Common Stock on an as-converted basis, such percentage reflects the Reporting Person’s voting percentage of the Issuer’s outstanding capital stock. If the percentage calculation was calculated in accordance with Rule 13d-3(d)(1) promulgated under the Exchange Act, excluding shares held by any of the Separately Filing Group Members, as to which the Reporting Person disclaims beneficial ownership, it would result in an applicable percentage of 85.1%.

name change became effective on May 17, 2011, upon the filing of a Certificate of Ownership and Merger with the Delaware Secretary of State.

On November 18, 2011, pursuant to the terms of that certain Series A-1 Convertible Preferred Stock Purchase Agreement (as amended, the “Series A-1 Stock Purchase Agreement”), dated as of April 25, 2011, among the Issuer and the investors referenced therein (the “Investors”), the Issuer issued an aggregate of 263,178 shares (the “Stage II Series A-1 Shares”) of its Series A-1 Convertible Preferred Stock, par value $.0001 per share (the “Series A-1 Stock”), to the Investors.  Such shares were issued in connection with the consummation of the Stage II Closing contemplated by the Series A-1 Stock Purchase Agreement at a purchase price of $81.42 per share resulting in aggregate proceeds to the Issuer of $21,427,952.76.  On December 14, 2011, pursuant to the terms of the Stock Purchase Agreement, the Issuer issued an aggregate of 263,180 shares (the “Stage III Series A-1 Shares” and together with the Stage II Series A-1 Shares, the “Series A-1 Shares”) of its Series A-1 Stock, to the Investors.  Such shares were issued in connection with the consummation of the Stage III Closing contemplated by the Series A-1 Stock Purchase Agreement at a purchase price of $81.42 per share resulting in aggregate proceeds to the Issuer of $21,428,115.60.

On April 23, 2013 and May 10, 2013, pursuant to the terms of that certain Series B Convertible Preferred Stock and Warrant Purchase Agreement (the “Series B Stock Purchase Agreement”), dated as of April 23, 2013, among the Issuer and the investors referenced therein (the “Series B Investors”), the Issuer issued to the Series B Investors (i) an aggregate of 701,235 shares (the “Series B Shares”) of its Series B Convertible Preferred Stock, par value $.0001 per share, and (ii) warrants to purchase, for an initial exercise price of $6.142 per share, up to an aggregate of 1,753,091 shares of Common Stock (the “Warrants” and together with the Series B Shares, the “Series B Securities”).  Such Series B Securities were issued in connection with the consummation of the Initial Closing and the Second Closing contemplated by the Series B Stock Purchase Agreement in exchange for aggregate proceeds received by the Issuer of $43,069,853.70.  The issuance of the Series B Securities resulted in an adjustment to the conversion price (the “Anti-Dilution Adjustment”) at which each share of the Issuer’s Series A-1 Stock, Series A-2 Stock par value $.0001 per share (the “Series A-2 Stock”), and Series A-3 Convertible Preferred Stock, par value $.0001 per share (the “Series A-3 Stock”), is convertible into shares of Common Stock.  As a result of the Anti-Dilution Adjustment, the effective conversion price of each share of Series A-1 Stock, Series A-2 Stock and Series A-3 Stock was reduced from $8.142 to $7.627.  Accordingly, each share of Series A-1 Stock, Series A-2 Stock and Series A-3 Stock is convertible into 10.675 shares of Common Stock.

On December 31, 2013, the Board declared a dividend (the “Series A-6 Dividend”) of seventy-seven (77) shares of Series A-6 Stock on and in respect of each share of Series A-5 Stock outstanding at the close of business on such date, resulting in the issuance to Nordic on such date of 496,111 shares of Series A-6 Stock.  Each share of Series A-6 Stock is convertible into ten (10) shares of Common Stock.

Following the Merger, the Short-Form Merger, the issuance of all Series A-1 Shares pursuant to the terms of the Series A-1 Stock Purchase Agreement, the issuance of all Series B Securities pursuant to the Series B Stock Purchase Agreement, the Anti-Dilution Adjustment and the Series A-6 Dividend, and assuming the conversion into Common Stock of all issued and outstanding shares of Preferred Stock of the Issuer, Nordic owns 14.4% of the Issuer’s outstanding capital stock, with 64,430 shares of Common Stock issuable to Nordic upon the conversion of 6,443 shares of Series A-5 Stock and 4,961,110 shares of Common Stock issuable to Nordic upon the conversion of 496,111 shares of Series A-6 Stock.

other factors, Nordic may dispose of or acquire additional shares of the Issuer in compliance with applicable law.

On March 29, 2011, the Issuer and Nordic entered into a Clinical Trial Services Agreement (the “Services Agreement”), a Work Statement NB-1 (the “Work Statement NB-1”) under such Services Agreement and a related Stock Issuance Agreement, as amended to date (the “Stock Issuance Agreement”). Pursuant to the Work Statement NB-1, Nordic is managing the Phase 3 clinical study (the “Phase 3 Clinical Study”) of BA058-SC and is being compensated for such services in a combination of cash and shares of stock.

In December 2011, the Issuer entered into an amendment to the Work Statement NB-1(the “First Amendment”). Pursuant to the original terms of the Work Statement NB-1, the study was to be conducted in 10 countries at a specified number of sites within each country. The terms of the First Amendment (1) provided for two additional countries (the United States and India) in which the study would be conducted, (2) specified a certain number of sites within each such additional country for the conduct of the study, and (3) amended various terms and provisions of the Work Statement NB-1 to reflect the addition of such countries and sites within the study’s parameters. Payments to be made by the Issuer to Nordic under the First Amendment are denominated in both euros and U.S. dollars and total up to €717,700 ($971,407) and $289,663, respectively, for the 15 additional study sites in India contemplated by the First Amendment and up to €1.2 million ($1.6 million) and $143,369, respectively, for the five additional study sites in the United States contemplated by the First Amendment.

In June 2012, the Issuer entered into a second amendment to the Work Statement NB-1(the “Second Amendment”). Pursuant to the original terms of the Work Statement NB-1, as amended by the First Amendment, the study was to be conducted in 12 countries at a specified number of sites within each country. The terms of the Second Amendment (1) increased the overall number of sites by adding sites in Europe, Brazil and Argentina and removing other sites, (2) specified a certain number of sites within each country for the conduct of the study, and (3) amended various terms and provisions of the Work Statement NB-1 to reflect additional services to be provided at existing sites and the addition of the new study sites within the study’s parameters. The Second Amendment also provided that cash payments to Nordic under the Clinical Trial Services Agreement as well as the payment of shares of stock under the related Stock Issuance Agreement will each be reduced by an amount of €11,941 ($16,162) per subject for any subjects enrolled in India or the United States. Such reductions shall be applied in pro rata monthly installments. Payments to be made by the Issuer to Nordic under the Second Amendment in connection with the additional services provided at existing sites and the conduct of the study at the new study sites are denominated in both euros and U.S. dollars and total of up to €3.7 million ($5.0 million) and $205,540, respectively.

Pursuant to the Work Statement NB-1, the Issuer is required to make certain per patient payments denominated in both euros and U.S. dollars for each patient enrolled in the Phase 3 Clinical Study followed by monthly payments for the duration of the study and final payments in two equal euro-denominated installments and two equal U.S. dollar-denominated installments.  Changes to the Clinical Study schedule may alter the timing, but not the aggregate amounts of the payments.

The Work Statement NB-1, as amended on December 9, 2011 and June 18, 2012, provides for a total of up to approximately €41.2 million ($55.7 million) of euro-denominated payments and a total of up to approximately $3.2 million of U.S. dollar-denominated payments over the course of the Phase 3 Clinical Study.  These payments may be adjusted based upon actual sites opened, work performed or number of patients enrolled.

On February 21, 2013, the Issuer entered into Work Statement NB-2 (the “Work Statement NB-2”) and Work Statement NB-3 (the “Work Statement NB-3”), each as contemplated by the terms of the Services Agreement.  Pursuant to Work Statement NB-2, Nordic continues providing clinical trial services relating to the Phase 2 clinical study of the Issuer’s BA058-TD product (the “Phase 2 Clinical Study”).  Payments in cash made or to be made by the Company to Nordic in connection with the Phase 2 Clinical Study services provided by Nordic are denominated in both euros and U.S. dollars and total up to

5

approximately €3.6 million ($4.8 million) and $257,853, respectively.  In addition, the Issuer agreed to issue to Nordic, shares of Series A-6 Stock having a value of approximately $2.9 million, as additional payment for services to be provided under Work Statement NB-2 and the Services Agreement.  Pursuant to Work Statement NB-3, Nordic is performing an extension study to evaluate six months of standard-of-care osteoporosis management following the completion of the Issuer’s BA058-SC Phase 3 clinical study.  Payments in cash to be made by the Issuer to Nordic under Work Statement NB-3 are denominated in both euros and U.S. dollars and total up to approximately €4.5 million (approximately $6.0 million based on the exchange rate as of February 21, 2013) and $579,495, respectively. In addition, the Company will issue to Nordic, shares of Series A-6 Stock having a value of up to the sum of approximately €4.5 million ($6.0 million) and $0.3 million, as additional payment for services to be provided under Work Statement NB-3 and the Services Agreement.  On February 21, 2013, the Issuer also entered into an amendment to the Stock Issuance Agreement in order to provide for the issuance of the additional Series A-6 Stock dividends contemplated by Work Statement NB-2 and Work Statement NB-3, as described above.

The Stock Issuance Agreement provides that Nordic is entitled to receive quarterly stock dividends, payable in shares of Series A-6 Stock or shares of common stock if the Issuer’s preferred stock has been converted in accordance with its amended certificate of incorporation, having an aggregate value of up to €36.8 million ($49.8 million) (the “Nordic Accruing Dividend”). In the event Nordic sells the shares of Series A-5 Stock or in the event the shares of Series A-5 Stock are converted into common stock in accordance with the Issuer’s amended certificate of incorporation, this right to receive the Nordic Accruing Dividend will terminate, but a right to receive an equivalent number of shares of Series A-6 Stock or common stock, as applicable, will remain with Nordic as a contractual right under the Stock Issuance Agreement.

The Nordic Accruing Dividend is determined based upon the estimated period that will be required to complete the Phase 3 Clinical Study. On the last business day of each calendar quarter (each, an “Accrual Date”), beginning with the quarter ended June 30, 2011, the Issuer has a liability to issue shares of Series A-6 Stock (or common stock, after the conversion of the Issuer’s preferred stock into common stock) to Nordic that is referred to as the Applicable Quarterly Amount and is equal to €36.8 million ($49.8 million) (subject to adjustment in accordance with the provisions of the Second Amendment for patients enrolled in India and the U.S.) minus the aggregate value of any prior Nordic Accruing Dividend accrued divided by the number of calendar quarters it will take to complete the Phase 3 Clinical Study. To calculate the aggregate number of shares due to Nordic in each calendar quarter, the Issuer converts the portion of €36.8 million ($49.8 million) to accrue in such calendar quarter into U.S. dollars using the simple average of the exchange rate for buying U.S. dollars with euros for all Mondays in such calendar quarter. The Issuer then calculates the aggregate number of shares to accrue in such calendar quarter by dividing the U.S. dollar equivalent of the Applicable Quarterly Amount, by the greater of (1) the fair market value as of the applicable Accrual Date or (2) $8.142 and rounding down the resulting quotient to the nearest whole number.  Such shares due to Nordic are issuable when declared or paid by the Board, which is required to do so upon Nordic’s request, or upon an event of sale. As of December 31, 2013, 496,111 shares of Series A-6 Stock were due to Nordic, or 4,961,110 shares of common stock on an as-converted basis.  The Dividend Shares were issued to Nordic in satisfaction of dividends accrued on the Series A-5 Stock through such date.

Except as set forth above, Nordic does not have any present plans which relate to or would result in:

(a) The acquisition by any person of additional securities of the Issuer, or the disposition of securities of the Issuer;

(b) An extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries;

(c) A sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries;

(f) Any other material change in the Issuer’s business or corporate structure including but not limited to, if the issuer is a registered closed-end investment company, any plans or proposals to make any changes in its investment policy for which a vote is required by section 13 of the Investment Company Act of 1940;

(g) Changes in the Issuer’s charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Issuer by any person;

(i) A class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Securities Exchange Act of 1934; or
