PRELIMINARY PROXY STATEMENT—SUBJECT TO COMPLETION
DATED OCTOBER 11, 2019

405 Eagleview Blvd.
Exton, Pennsylvania 19341
(484) 713-6000

                ,October 28, 2019

Dear Stockholders:

         On September 12, 2019, Fibrocell Science, Inc. ("Fibrocell"), Castle Creek Pharmaceutical Holdings, Inc. ("Castle Creek"), and Castle Creek Merger Corp. ("Merger Sub") entered into an Agreement and Plan of Merger (as amended from time to time, the "Merger Agreement"), providing for the acquisition of Fibrocell by Castle Creek. Pursuant to the terms of the Merger Agreement, Merger Sub, a wholly-owned subsidiary of Castle Creek, will merge with and into Fibrocell (the "Merger"), with Fibrocell surviving the Merger as a wholly-owned subsidiary of Castle Creek.

         If the Merger is completed, stockholders will have the right to receive $3.00 in cash, without interest and less any applicable withholding taxes, for each share of common stock, par value $0.001 per share, of Fibrocell ("Common Stock") that they own immediately prior to the effective time of the Merger (the "Effective Time").

         You are cordially invited to a special meeting of stockholders (the "Special Meeting") to be held at the offices of Hogan Lovells US LLP located at 1735 Market St., Floor 23, Philadelphia, PA 19103 on ,December 10, 2019, at 8:30 a.m., Eastern Time. The Special Meeting is being held for you to consider and vote on a proposal to adopt the Merger Agreement and related matters.Your vote is important. Whether or not you expect to attend the meeting, we encourage you to vote your shares as promptly as possible in order to make certain that you are represented at the meeting. You may vote over the Internet, as well as by telephone or by mailing a proxy or voting instruction card. If you are a "street name" holder (a holder whose shares are held through a broker, bank, trust company or other nominee), in order for your shares to be represented at the Special Meeting, you should instruct your broker, bank, trust company or other nominee as to how to vote your shares by following the directions provided to you by your broker, bank, trust company or other nominee. The Merger cannot be completed unless the Merger Agreement is adopted by the affirmative vote of the holders of a majority of the outstanding shares of Common Stock as of the record date entitled to vote thereon. Therefore, your failure to vote, or failure to instruct your broker, bank, trust company or other nominee to vote, will have the same effect as a vote"AGAINST" the Merger.

         After careful consideration, the Fibrocell board of directors (the "Fibrocell Board"), on September 12, 2019, approved the Merger Agreement and determined that it is fair to, advisable and in the best interests of Fibrocell and its stockholders for Fibrocell to enter into the Merger Agreement and to effect the Merger and the other transactions contemplated thereby. The Fibrocell Board accordingly recommends that you vote "FOR" the adoption of the Merger Agreement and the other proposals described in the enclosed proxy statement.

         The obligations of Fibrocell and Castle Creek to complete the Merger are subject to the satisfaction or waiver of several conditions set forth in the Merger Agreement. The accompanying proxy statement provides you with detailed information about the Special Meeting, the Merger Agreement, the Merger and other important information related to the Merger. A copy of the Merger Agreement is enclosed asAnnex A to the accompanying proxy statement. We encourage you to read the enclosed proxy statement and the Merger Agreement carefully and in their entirety.

         Thank you in advance for your consideration of this matter and continued support.

Sincerely,

        The principal executive offices of Merger Sub are located at 233 Mt. Airy Road, 1st Floor, Basking Ridge, NJ, 07920, and its telephone number is (862) 286-0400.


The Merger

        A copy of the Merger Agreement is attached asAnnex A to this proxy statement and is incorporated herein by reference. We encourage you to read the entire Merger Agreement carefully and in its entirety because it is the principal document governing the Merger. For more information about the Merger Agreement, see "The Merger Agreement" beginning on page 67.

The Merger (see page 28)

        If the Merger is completed, at the Effective Time of the Merger, Merger Sub will merge with and into Fibrocell. Fibrocell will survive the Merger as a wholly-owned subsidiary of Castle Creek. We intend to complete the Merger as soon as reasonably practicable and currently expect to complete the Merger in the fourth quarter of 2019. The Merger is subject to regulatory clearances (to the extent required) and other customary closing conditions, in addition to the approval of holders of Common Stock of Fibrocell at the Special Meeting. It is possible that factors outside the control of Fibrocell and Castle Creek could result in the Merger being completed at a later time or not at all.

Merger Consideration (see page 67)

        At the Effective Time, each share of our Common Stock issued and outstanding immediately prior to the Merger (other than shares held directly by Castle Creek or Merger Sub and shares owned by Company stockholders who have exercised their appraisal rights under Delaware law) will be converted into and thereafter represent the right to receive $3.00 in cash, without interest (the "Merger Consideration"), subject to any withholding of taxes required by applicable law. Upon completion of the Merger, all such shares of Common Stock shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and shall thereafter represent only the right to receive the Merger Consideration.

Treatment of Preferred Stock (see page 68)

        After the Effective Time, each share of the Company's Series A Convertible Preferred Stock issued and outstanding immediately prior to the Merger (the "Preferred Stock") will remain outstanding (until converted by the holders thereof pursuant to the Consent and Termination Agreements, as defined below), and will thereafter only represent the right to receive an amount in cash, without interest, equal


Table of Contents

to (i) the number of shares of Common Stock underlying each share of Preferred Stock multiplied by (ii) the Merger Consideration (the "Conversion Amount").

Consent and Termination Agreements

        In addition, as consideration for entry into the Consent and Termination Agreements, the holders of Preferred Stock will each receive a promissory note to be issued by Merger Sub immediately prior to the Merger, in each case for an amount equal to (and in addition to) the aggregate Conversion Amount such party is entitled to in connection with such party's ownership of shares of Preferred Stock.

Treatment of Warrants (see page 68)

        After the Effective Time, each outstanding Company warrant to purchase shares of Common Stock shall be generally entitled to receive (i) upon any subsequent exercise, an amount equal to the Merger Consideration less the exercise price for such warrant, or (ii) if eligible pursuant to the terms of the warrant, upon notification by the holder of such warrant to the Company within 30 days of the Effective Time, an amount equal to the Black-Scholes value of the warrant (as described in such warrant).

Appraisal Rights (see page 89)

        Shares of Common Stock held by stockholders who have properly exercised appraisal rights under Section 262 of the Delaware General Corporation Law ("DGCL") (and have not withdrawn such exercise or lost such rights) will not be converted into the right to receive the Merger Consideration, but will instead be converted into the right to receive payment in cash for the fair value of their shares as determined in accordance with Section 262 of the DGCL. The fair value of the shares as determined in accordance with Section 262 of the DGCL may be more or less than (or the same as) the Merger Consideration. Stockholders who wish to exercise appraisal rights must comply fully with all applicable requirements of Section 262 of the DGCL, which is summarized in this proxy statement and attached asAnnex C to this proxy statement. Failure to follow exactly the procedures specified under Section 262 of the DGCL may result in the loss of appraisal rights. Because of the complexity of Section 262 of the DGCL relating to appraisal rights, if you are considering exercising your appraisal rights we encourage you to seek the advice of your own legal counsel.

The Special Meeting (see page 21)

        The Special Meeting of stockholders is scheduled to be held at the offices of Hogan Lovells US LLP located at 1735 Market St., Floor 23, Philadelphia, PA 19103 on ,December 10, 2019, at 8:30 a.m., Eastern Time. The Special Meeting is being held in order to consider and vote on the following:


Table of Contents

        Only holders of record of Common Stock at the close of business on ,October 18, 2019, the record date for the Special Meeting ("Record Date"), are entitled to notice of, and to vote at, the Special Meeting or any adjournment or postponement of the Special Meeting. At the close of business on the Record Date, 9,758,332 shares of Common Stock were issued and outstanding.

        A quorum is necessary to transact business at the Special Meeting. Holders of a majority of all issued and outstanding shares of Common Stock entitled to vote as of the Record Date must be present in person or represented by proxy at the Special Meeting in order for there to be a quorum. Shares of Common Stock represented at the Special Meeting but not voted, including shares for which a stockholder directs an "abstention" from voting, will be counted as present for purposes of establishing a quorum. Broker non-votes (shares held by a broker, bank, trust company or other nominee that is present in person or by represented by proxy at the Special Meeting but with respect to which the broker or other stockholder of record is not instructed by the beneficial owner of such shares how to vote on a particular proposal and the broker does not have discretionary voting power on such proposal), if any, will not be counted as present for purposes of establishing a quorum. If a quorum is not present in person or represented by proxy, the Special Meeting may be adjourned until the holders of the number of shares of Common Stock required to constitute a quorum are present in person or represented by proxy.

        You may cast one vote on each matter submitted to a vote at the Special Meeting for each share of Common Stock you own at the close of business on the Record Date. The Merger Proposal requires the affirmative vote of the holders of a majority of the outstanding shares of Common Stock as of the Record Date entitled to vote thereon. The Compensation Proposal and the Adjournment Proposal each requires the affirmative vote of the holders of a majority of the shares of Common Stock present in person or represented by proxy at the Special Meeting and entitled to vote thereon.

        Your failure to vote, or failure to instruct your broker, bank, trust company or other nominee to vote, will have the same effect as a vote against the Merger Proposal, but, assuming a quorum is present at the Special Meeting, will have no effect on the Compensation Proposal or the Adjournment Proposal.

Recommendation of the Fibrocell Board and Reasons for the Merger (see page 46)

        After careful consideration, at a meeting held on September 12, 2019, the members of the Fibrocell Board present unanimously approved the Merger Agreement and determined that it is fair to, advisable and in the best interests of Fibrocell and its stockholders for Fibrocell to enter into the Merger Agreement and effect the Merger and the other transactions contemplated thereby. Fibrocell directors Julian P. Kirk and Marcus E. Smith voluntarily recused themselves from, and did not attend, the September 12, 2019 meeting of the Fibrocell Board in light of their respective interests described in the section entitled "The Merger—Interests of Directors and Executive Officers in the Merger" beginning on page 61. The Fibrocell Board accordingly recommends that our stockholders vote"FOR" the adoption of the Merger Agreement. The Fibrocell Board considered many factors in reaching its conclusion, including, without limitation, the value that stockholders would realize in the Merger, the current and historical market prices of Fibrocell shares relative to the $3.00 per share Merger Consideration, the fact that the Merger Consideration consists entirely of cash and the risks associated with the implementation of Fibrocell's business plan.

Opinion of Fibrocell's Financial Advisor (see page 51)

        The Fibrocell Board engaged Canaccord Genuity LLC ("Canaccord Genuity") to provide financial advisory services and to assist the Fibrocell Board in the consideration and evaluation of potential strategic transactions on Fibrocell's behalf. At a meeting of the Fibrocell Board held on September 12, 2019 to evaluate the Merger, Canaccord Genuity delivered to the Fibrocell Board an oral opinion, which opinion was confirmed by delivery of a written opinion, dated September 12, 2019, to the effect that, as of that date and based upon and subject to certain assumptions, factors and qualifications set forth in the written opinion, the consideration of $3.00 per share in cash, without interest, to be received by holders of Common Stock (other than certain excluded holders referenced in the opinion) in the Merger was fair, from a financial point of view, to such holders. Canaccord Genuity did not express any view on, and its opinion did not address, any other term or aspect of any other agreements or arrangements contemplated by the Merger Agreement or entered into in connection with the Merger (including, without limitation, any agreements or arrangements with any holder of Preferred Stock, Convertible Notes, warrants or options).

        The full text of Canaccord Genuity's written opinion is attached to this proxy statement asAnnex B and is incorporated into this proxy statement by reference. The description of Canaccord Genuity's opinion set forth in this proxy statement is qualified in its entirety by reference to the full text of such opinion. Fibrocell stockholders are encouraged to read Canaccord Genuity's opinion carefully and in its entirety for a description of the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Canaccord Genuity in connection with its opinion. Canaccord Genuity's opinion addressed to the Fibrocell Board was only one of many factors considered by the Fibrocell Board in its evaluation of the Merger and only addresses the fairness, from a financial point of view and as of the date of the opinion, of the $3.00 per share in cash, without interest, to be received in the Merger by holders of Common Stock (other than certain excluded holders referenced in the opinion). Canaccord Genuity's opinion does not address the relative merits of the Merger as compared to other business strategies or transactions that might be available to Fibrocell, nor does it address the underlying business decision of Fibrocell to proceed with the Merger. Canaccord Genuity's opinion was directed to and for the information of the Fibrocell Board only (in its capacity as such) in connection with its evaluation of the Merger and does not constitute advice or a recommendation to the Fibrocell Board or any other person as to how the Fibrocell Board or such person should vote with respect to the Merger or otherwise act on any other matter with respect to the Merger.

        See "The Merger—Opinion of Fibrocell's Financial Advisor" beginning on page 51.

Treatment of Stock Options (see page 69)

        Each stock option to purchase shares of Common Stock issued under Fibrocell's equity incentive plans outstanding immediately prior to the Effective Time, whether vested or unvested, will be converted into the right to receive with respect to each share of Common Stock underlying the stock option (whether vested or unvested) an amount in cash equal to the Merger Consideration minus the exercise price of such stock option, less applicable taxes required to be withheld. If the per share exercise price of a stock option is equal to or greater than the Merger Consideration, the stock option shall terminate and be canceled for no consideration. See "The Merger—Interests of Directors and Executive Officers in the Merger" beginning on page 61 and "The Merger Agreement—Treatment of Stock Options" beginning on page 69.

Interests of Directors and Executive Officers in the Merger (see page 61)

        In considering the recommendation of the Fibrocell Board that our stockholders vote to approve the Merger Proposal, stockholders should be aware that our directors and executive officers have

interests in the Merger that may be different from, or in addition to, the interests of our stockholders generally and that may present actual or potential conflicts of interest. A special committee (the "Special Committee"), composed of disinterested directors of the Fibrocell Board, Douglas J. Swirsky, Kelvin D. Moore and Marc B. Mazur, was aware of and considered these potential interests when it evaluated and negotiated the Merger Agreement, and recommended that the Fibrocell Board approve the Merger Agreement and recommend approval of the Merger Agreement by Fibrocell's stockholders. In addition, the Fibrocell Board was aware of and considered these potential interests, among other matters, in approving the Merger Agreement and in recommending to stockholders the approval of the Merger Proposal, the Compensation Proposal and the Adjournment Proposal. These interests include the following:

Material U.S. Federal Income Tax Consequences of the Merger (see page 85)

        The Merger generally will be a taxable transaction for U.S. federal income tax purposes. In general, U.S. holders (as defined in "Material U.S. Federal Income Tax Consequences of the Merger") whose shares of Common Stock are converted into cash in the Merger will recognize gain or loss for U.S. federal income tax purposes in an amount equal to the difference, if any, between the amount of cash received with respect to such shares (determined before the deduction of any applicable withholding taxes) and the U.S. holder's adjusted tax basis in such shares. Non-U.S. holders (as defined in "Material U.S. Federal Income Tax Consequences of the Merger") generally will not be subject to U.S. federal income tax as a result of the non-U.S. holder's receipt of cash in exchange for shares of Common Stock pursuant to the Merger, subject to certain exceptions discussed in "Material U.S. Federal Income Tax Consequences of the Merger," but may be subject to tax under non-U.S. income tax laws.

        You should read the section entitled "Material U.S. Federal Income Tax Consequences of the Merger" beginning on page 85 for a more detailed discussion of the U.S. federal income tax consequences of the Merger. Tax matters can be complicated and the tax consequences of the Merger to you will depend on your particular tax situation. You are encouraged to consult your tax advisor to determine the tax consequences of the Merger to you.

No Financing Condition; Financing Cooperation (see page 65)

bona fide written unsolicited Acquisition Proposal that the Fibrocell Board determines in good faith is, or determines in good faith is reasonably likely to result in, a Superior Proposal and that the failure to take such action would be reasonably likely to breach the directors' fiduciary duties under applicable law, Fibrocell may under certain circumstances furnish information to, and engage in discussions or negotiations with, the third party making such Acquisition Proposal.

        The terms "Superior Proposal" and "Acquisition Proposal" are defined under "The Merger Agreement—No Solicitation of Other Offers" beginning on page 80.

Changes in Board Recommendation (see page 81)

        Under the Merger Agreement, subject to certain exceptions, neither the Fibrocell Board nor any committee thereof may (i) withdraw, change, qualify, withhold or modify, or publicly propose to do any of the foregoing, in a manner adverse to Castle Creek or Merger Sub, its recommendation that Fibrocell's stockholders adopt the Merger Agreement or (ii) adopt, approve or recommend, any Acquisition Proposal or publicly propose to do the same.

        Notwithstanding the foregoing limitations, prior to the approval of the Fibrocell stockholders of the Merger Proposal, the Fibrocell Board may, under certain circumstances, change its recommendation that Fibrocell's stockholders adopt the Merger Agreement or terminate the Merger Agreement pursuant to the terms of the Merger Agreement to accept a Superior Proposal, only if the Fibrocell Board has determined in good faith, after, among other things, consultation with its financial advisors and outside legal counsel, that the failure to do so would reasonably be expected to be a breach of the directors' fiduciary duties under applicable law. Prior to changing its recommendation that stockholders adopt the Merger Agreement or terminating the Merger Agreement pursuant to the terms of the Merger Agreement to accept a Superior Proposal, the Fibrocell Board must provide written notice to Castle Creek at least four business days prior to such action and during such notice period must negotiate in good faith with Castle Creek regarding, and consider in good faith, any revisions to the Merger Agreement proposed by Castle Creek.

Termination of the Merger Agreement (see page 82)
