Upcoming Investigational New Drug Application Submissions

Facility Expansion in Houston, TX

Leon Office, Asia, Strategic Marketing Agreement

SBA Loan Extinguishment

Research Grant Agreement with University of Texas MD Anderson Cancer Center

Kiromic BioPharma (NASDAQ: KRBP), a pre-clinical stage biotechnology company using its proprietary DIAMOND^® artificial intelligence (“A.I.”) platform to improve drug discovery and development with a therapeutic focus on immune-oncology, today announced its quarterly results for the three months ended March 31, 2021, and provided an update on its corporate developments.

“Kiromic BioPharma achieved important scientific and operational milestones during the year that we believe have us well positioned for preparing our staff and our facilities for the first in-human dosing in Q3 2021,” said Dr. Maurizio Chiriva-Internati, PhD, CEO and President of Kiromic BioPharma. “We are thankful to our employees and collaborators who have maintained this high level of execution this year. From their efforts, we plan to submit two investigational new drug applications to the United States Food and Drug Administration by the end of May 2021.”

Our approach and goal are to defeat cancer by developing immunotherapies by improving target discovery and validation. With better targets, we believe our therapies will be more effective than the current array of immunotherapies using older targets.

Corporate and Scientific Highlights

Events Occurring during the three months ended March 31, 2021

• Facility Expansion in Houston, TX - On March 22, 2021, we executed a lease expansion within our premises in Houston, TX. The amended lease agreement will commence on August 1, 2021 under an operating lease agreement that is noncancelable from commencement until May 1, 2024. The amended lease agreement adds approximately 15,385 square feet to the current facility. Total square feet will be approximately 38,223 square feet.
• Leon Office, Asia, Strategic Marketing Agreement – On January 28, 2021, we executed a strategic alliance agreement with Leon Office, Asia (H.K.) (“Leon”) a company established under existing laws of Hong Kong. Leon will act as an independent business development advisor on the behalf of the Company. Leon will seek to introduce organizations and individuals that will create business development opportunities for the Company, to expand the Company’s reach to international markets with a focus on certain Asian markets and to increase brand recognition and exposure through developing liaisons, collaborations, branches and subsidiaries. They will also use commercially reasonable efforts to research the Asian market, with a primary, but not exclusive, focus on determining the most suitable structures for the development of medical partnerships or joint ventures with scientific partners in the Asian market with a mission to test products to be created by the joint venture resulting from such partnership and to develop validation programs for any products produced by such joint venture, including programs for clinical trials and human testing and, ultimately, for product certification. The cost of the agreement is $360,000 annually, payable in four quarterly installments.
• SBA Loan Extinguishment - On February 16, 2021 the Small Business Administration (“SBA”) granted forgiveness of our SBA loan and all applicable interest. On the date of forgiveness, the principal and accrued interest totaled $105,800. The forgiveness was classified as a gain on loan extinguishment in the consolidated statement of operations.

Events occurring after March 31, 2021 until May 14, 2021

• Research Grant Agreement with University of Texas MD Anderson Cancer Center – On April 8, 2021, we entered into a letter of intent (the “Letter of Intent”) with the University of Texas MD Anderson Cancer Center (“MD Anderson”) pursuant to which MD Anderson shall receive a research grant from us entitled, “Validation of biomarker isomeso for pancreatic cancer,” which is aimed at discovering new cancer-specific antigen targets (the “Grant”). The total costs to us to be paid in connection with the Grant shall be $300,000. Pursuant to the Letter of Intent, the Grant shall commence on April 1, 2021 and end on March 31, 2022.
• Upcoming Investigational New Drug Application Submissions – We are planning to submit two investigational new drug (“IND”) applications to the United States Food and Drug Administration by the end of May 2021. These INDs will be for our ALEXIS-PRO-1 and ALEXIS-ISO-1 product candidates. ALEXIS-PRO-1 is our allogeneic gamma delta chimeric T cell therapy product candidate targeting PD-L1. ALEXIS-ISO-1 is our allogenic gamma delta CAR-T cell therapy product candidate targeting Isomesothelin (the isoform of Mesothelin).

Q1 2021 Financial Highlights

Cash Position: Cash and cash equivalents were $7,335,300 as of March 31, 2021, compared to $10,150,500 as of December 31, 2020. The difference is attributable to cash outflows of $2,635,900, $44,700, and $134,600 for operating activities, investing activities, and financing activities respectively.

R&D Expenses: Our research and development expenses increased by $857,500, (83.41%), to $1,885,600 for the three months ended March 31, 2021. The increase was attributable to increased headcount, manufacturing, and experimentation costs for our ALEXIS-ISO-1 product candidate.

This increase was primarily due to increased headcount, stock compensation expenses from prior year grant modifications, and professional services.
