Item 1.01 Entry into
a Material Definitive Agreement
On December 23, 2020, Cellectar Biosciences, Inc.,
a Delaware corporation (the “Company”), entered into an underwriting agreement (the “Underwriting Agreement”)
with Oppenheimer & Co. Inc. as representative of the several underwriters named therein (the “Representative”).
Pursuant to the Underwriting Agreement, the Company agreed to sell to the Representative 18,148,136 shares of common stock (the
“Common Shares”), par value $0.00001 per share, of the Company (“Common Stock”) at a public offering price
of $1.35 per share of common stock, prior to deducting underwriting discounts and commissions and estimated offering expenses (the
“Public Offering”). The Common Shares in the Public Offering were offered pursuant to a registration statement on Form S-3
(File No. 333-244362), which was declared effective by the Securities and Exchange Commission on August 20, 2020.
On December 23, 2020, in a separate
concurrent private placement, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with
certain purchasers named therein (the “Purchasers”), pursuant to which the Company agreed to issue and sell, 1,518.5180
shares of Series D convertible preferred stock (the “Preferred Shares”). The Preferred Shares are convertible
into a number of shares of common stock equal to $13,500 divided by $1.35 (or 10,000 shares of common stock for each share of Series D
Preferred Stock converted), at a price of $13,500 per share of Series D Preferred Stock (the “PIPE” and together
with the Public Offering, the “Offerings”). The Preferred Shares will only be convertible into common stock upon receipt
of stockholder approval of the issuance of the underlying shares of common stock (“Stockholder Approval”) as required
by Nasdaq Marketplace Rule 5635(d) at a special stockholder meeting to be called for that purpose. The Preferred Sharers
and the shares of our common stock issuable upon the exercise of the Series D Preferred Stock issued in the PIPE were offered
pursuant to the exemption provided in Section 4(a)(2) under the Securities Act of 1933, as amended (the “Securities
Act”) and Rule 506(b) promulgated thereunder.
The net proceeds of the Offerings to the
Company, after deducting the underwriting discounts and commissions, placement agency fees and estimated offering expenses payable
by the Company were approximately $41.4 million.
The Underwriting
Agreement also contains representations, warranties, indemnification and other provisions customary for transactions of this nature.
Pursuant to the Underwriting Agreement, the Company and its directors and officers agreed, subject to certain exceptions, not to
offer, issue or sell any shares of common stock or securities convertible into or exercisable or exchangeable for shares of common
stock for a period of ninety (90) days following December 28, 2020 without the prior written consent of the Representative.
Pursuant to the
Purchase Agreement, the Company has agreed to hold a special meeting of stockholders at the earliest practical date in any event
on or before March 31, 2021 for the purpose of obtaining Stockholder Approval. In connection with the entry into the Purchase
Agreement, the Company and the Purchasers entered into a registration rights agreement (the “Registration Rights Agreement”),
pursuant to which the Company is required to file a registration statement on Form S-1 or Form S-3 within 30 calendar
days of the closing of the PIPE to provide for the resale of the shares of Common Stock issuable upon the exercise of the Preferred
Shares. The Company will be obligated to use its reasonable best efforts to keep any registration statement effective until the
earlier of (i) the date on which the shares of Common Stock issuable upon the exercise of the Preferred Shares subject to
the registration statement may be sold without registration pursuant to Rule 144 under the Securities Act, or (ii) the
date on which all of the shares of Common Stock subject to the registration statement have been sold under the registration statement
or pursuant to Rule 144 under the Securities Act or any other rule of similar effect.
The foregoing summaries of the Underwriting
Agreement, Securities Purchase Agreement and Registration Rights Agreement do not purport to be complete and are subject to, and
qualified in their entirety by, such documents, which are incorporated herein by reference.
This Current Report on Form 8-K does
not constitute an offer to sell any securities or a solicitation of an offer to buy any securities, nor shall there be any sale
of any securities in any state or jurisdiction in which such an offer, solicitation or sale would be unlawful prior to registration

Friedrich LLP relating to the legality of the issuance and sale of the Shares is attached as Exhibit 5.1 hereto.
