On page 44, you disclose that in 2013, you expect cash needs of up to $20 million to continue your research and development efforts, that you have not completed your efforts to establish a stable recurring source of revenues sufficient to cover your operating costs for the next twelve months, and have financed your operations primarily through sales of stock and the issuance of convertible promissory notes.

11.  
Please explain why the second paragraph of this section states that the tabular disclosure assumes a 100% share exchange by Actinium shareholders.
 
RESPONSE:
On December 28, 2012, Cactus Ventures, Inc. entered into a transaction, pursuant to which Cactus acquired 100% of the issued and outstanding equity securities of Actinium Pharmaceuticals, Inc., in exchange for the issuance of approximately 99% of the issued and outstanding common stock, par value $0.01 per share, of the Cactus. The share exchange closed on December 28, 2012.  As a result of the share exchange, the former shareholders of Actinium became the controlling shareholders of Cactus. At the time of the filing of the Form 8-K on January 2, 2013, Cactus had not received all of the signature pages to the Share Exchange Agreement from the Actinium exchanging shareholders. We included the persons for whom we did not receive actual share exchange signature pages in the total issued and outstanding share count because the process of obtaining the remaining signature pages was simply to document the share exchange transaction that had already been approved by the Actinium shareholders in September 2012.
 
12.  
Please disclose the person or persons who have sole or shared voting and/or investment power over the securities owned by each legal entity. See Item 507 of Regulation S-K and, for guidance, refer to Questions 140.01 and 140.02 of the Division of Corporation Finance's Compliance and Disclosure Interpretations of Regulation S-K.
 
RESPONSE:
We have revised the Selling Stockholder table to include the person or persons who have sole or shared voting and/or investment power over the securities owned by each legal entity.
 
13.
Numerous footnotes contain disclaimers of beneficial ownership. To the extent that you retain these disclaimers, please provide us with a legal analysis supporting your belief that beneficial ownership disclaimers are proper outside of filings on Schedules 13D and 13G, and revise to disclose who has voting and/or dispositive power over the disclaimed shares. For guidance, refer to Section III.A.4 of SEC Release No. 33-5808. Alternatively, delete the disclaimers.
 
RESPONSE:
We have deleted the disclaimers.

Additionally, explain how the substantial doubt regarding your ability to continue as a going concern impacts your business plan.
 
RESPONSE:
We have added additional disclosure to the document to address these points.

Please explain why the Share Exchange was conducted in two phases and why you intend to "continue to exchange [your] shares of common stock for shares of Actinium held by the remaining Actinium Shareholders." Provide us with a legal analysis as to whether the Share Exchange has been completed and tell us whether you are attempting to register shares of common stock held by Actinium Shareholders that have not already been exchanged. For guidance, refer to Question 139.06 of the Division of Corporation Finance's Compliance and Disclosure Interpretations of Securities Act Sections.
 
RESPONSE:
On December 28, 2012, Cactus Ventures, Inc. entered into a transaction, pursuant to which Cactus acquired 100% of the issued and outstanding equity securities of Actinium Pharmaceuticals, Inc., in exchange for the issuance of approximately 99% of the issued and outstanding common stock, par value $0.01 per share, of the Cactus. The share exchange closed on December 28, 2012.  As a result of the share exchange, the former shareholders of Actinium became the controlling shareholders of Cactus. The share exchange was approved by a majority of Actinium Corporation’s stockholders in September 2012.  Although the share exchange was approved by the Actinium Corporation shareholders (which includes over 200 shareholders), we only included those shareholders in the December 28, 2012 share exchange close that had actually delivered a signed share exchange agreement to the Company.   We reported a second share exchange on March 7, 2013, and we closed on a third share exchange on August 22, 2013.   The March and July share exchange agreements included those Actinium Corporation shareholders who had delivered signed share exchange agreements after December 28, 2012.
 
We are currently in process of collecting the remaining signatures of the exchanging Actinium Corporation shareholders.  Since the share exchange was approved by the Actinium Corporation shareholders, we are registering the shares of common stock held by Actinium Corporation shareholders that have not provided a signed share exchange agreement.  The process of collecting the remaining actual signature pages to the share exchange agreement and exchanging the corresponding Actinium Corporation shares for new Actinium shares has been and is being performed only to properly document what already has been approved by the shareholders in September 2012 and closed upon on December 28, 2012.
 
The table below sets forth the share exchange dates, the number of shares exchanged, and the percentage of Actinium Corporation shareholders that have exchanged their shares for the Company’s shares:

Also disclose the minimum number of months that you will be able to conduct your planned operations using currently available capital resources, assuming the exercise of 25%, 50%, 75%, 100% or none of the warrants. Finally, discuss your alternative plans for funding, assuming none of the warrants are exercised. See Item 303(a) of Regulation S-K.

Please disclose the minimum amount of time per week that Mr. Traversa devotes to your company. Also, address whether his outside employment creates a material risk of conflicts of interest and, if so, how such conflicts will be resolved.
 
RESPONSE:
Mr. Traversa devotes a minimum of 40 hours per week to the Company.  Relmada Therapeutics, Inc. is an unrelated company to us and specializes in pain management, which is unrelated to our business.  We do not believe that Mr. Traversa’s outside employment creates a material risk of conflicts of interest.

Security Ownership of Certain Beneficial Owners and Management, page 53
 
29.  
Your footnote disclosure suggests that you only included options and warrants in the table if they vested as of December 28, 2012. A person is deemed the beneficial owner of a security if that person has the right to acquire beneficial ownership of such security within 60 days, including, but not limited to, any right to acquire through the exercise of any option, warrant or right. See Exchange Act Rule 13d-3(d)( 1 )(i) and Instruction 2 to Item 403 of Regulation S-K. If the options or warrants are exercisable within 60 days, they should be included in the table. Please revise the table and footnotes accordingly.
 
RESPONSE:
We have updated the beneficial ownership table and footnotes to include share ownership up to July 23, 2013 and any options and warrants, if any, exercisable by such holder within 60 days.
 
30.  
We note your disclosure in footnote 6 regarding the dissolution of Actinium Holdings by Bermuda authorities and its impact on beneficial and other ownership rights until the reinstatement of Actinium Holdings. Despite this issue, please disclose the person or persons who would otherwise have sole or shared voting and/or investment power over the securities beneficially owned by AHLB Holdings, LLC. See Instruction 2 to Item 403 of Regulation S-K.
 
RESPONSE:
Actinium Holdings Ltd. (“AHL”) entered into a Share Exchange Agreement with the Company and a Lock-up Agreement contemporaneously with the filing of the amended Form S-1 (and had been previously reinstated).  The disclosure in the amended Form S-1 has been modified accordingly.  We have also disclosed the persons that share voting and/or investment power of the securities held of record by AHL.

Certain Relationships and Related Transactions
 
Transactions With Related Persons, page 55
 
31.
Please provide us with your analysis as to whether Memorial Sloan-Kettering Cancer Center and/or related entities constitute your promoters. See Rule 405 of Regulation C.
 
If necessary, provide the disclosure required by Item 404(c) of Regulation S-K. See Item 404(d)(2) of Regulation S-K.
 
RESPONSE:
We do not believe that any of Memorial Sloan-Kettering Cancer Center, Inc. (“MSKCC”) and its related entities, consisting, for purposes of this response, of Sloan-Kettering Cancer Institute, Inc., AHL and AHLB Holdings, LLC (such entities, together with MSKCC, the "MSKCC Parties") is a promoter of the registrant, Actinium Pharmaceuticals, Inc. (f/k/a Cactus Ventures, Inc.).   The registrant was founded and organized in 1997, and the MSKCC Parties had no connection with the registrant until the share exchange in which the registrant was acquired by the stockholders of Actinium Corporation, f/k/a Actinium Pharmaceuticals, Inc. ("AC") and AC became a subsidiary of the registrant.  With respect to AC, as a predecessor of the registrant, AC was incorporated in June 2000; however, the License and Development Agreement between AC (including an affiliated entity) and Sloan-Kettering Cancer Institute was not entered into until February 2002.  None of the MSKCC Parties directly or indirectly acquired any equity in AC until March 2010, when shares of AC were indirectly donated to MSKCC.
 
In any case, we respectfully note that no disclosure is required with respect to the role of any promoter in the organization and founding of AC or the registrant, since, under Item 404(c)(1) of Regulation S-K, disclosure with respect to promoters is required only if the registrant has "had a promoter at any time within the past five fiscal years."  We do not consider the share exchange to constitute a founding or organization of the registrant; however, even if one were to take a contrary position, the MSKCC Parties did not take any part in the negotiation of the share exchange or its terms and are receiving their shares solely in consideration for property (i.e., shares of AC) on terms identical to those of other stockholders of AC of the same classes, as determined pursuant to AC's governing documents and the Share Exchange Agreements between AC, the registrant and the stockholders of AC.
 
Because certain of the MSKCC Parties may be deemed to be acquiring control of the registrant in the share exchange and because the registrant was a shell company prior to the share exchange, we agree that, under Items 404(c)(2) and 404(d)(2) of Regulation S-K, the disclosure required by paragraphs (c)(1)(i) and (c)(1)(ii) of Item 404 is required.  The disclosure in the amended Form S-1 under "Certain Relationships and Related Transactions" meets the requirements of those paragraphs.
