Kiromic BioPharma, Inc. (NASDAQ:KRBP) ("Kiromic" or the "Company"), a clinical-stage fully integrated biotherapeutics company using its proprietary DIAMOND^® artificial intelligence (AI) and big data mining platform to discover and develop cell and gene therapies with a therapeutic focus on immuno-oncology, today announces financial results for the fourth quarter and fiscal year ended December 31, 2021.

"We are extremely encouraged by the progress the Company demonstrated in the fourth quarter. Our team's unified efforts are strictly focused on achieving our goal of beginning the activation of the clinical trial for our first oncology cell therapy candidate by the end of the fourth quarter of 2022," stated Pietro Bersani, Kiromic BioPharma's Interim Chief Executive Officer. "We have been intensely preparing for this milestone, ensuring we have the right team, the right capabilities, and the right processes in place to achieve this objective. Our team has been executing critical advancements - occurring simultaneously - across our research and development, clinical trial preparation, facility expansion, and manufacturing operations, among other functions. We look forward to more opportunities to communicate with our shareholders as we demonstrate the Company's overall progress."

Fiscal Year Ended 2021 Financial Highlights:

• Cash Position: Cash and cash equivalents were $25,353,900 as of December 31, 2021, compared to $10,150,500 as of December 31, 2020. The difference is attributable to cash outflows of $20,321,500, and $1,810,800 for operating activities, and investing activities, respectively. There were cash inflows of $37,335,700 from financing activities.

• R&D Expenses: Our research and development expenses increased by $6,314,900, or 124.98%, to $11,367,800 for the year ended December 31, 2021 from $5,052,900 for the year ended December 31, 2020. The increase was attributable to increased headcount, manufacturing, and experimentation costs for the development of our ALEXIS clinical platform.

• G&A Expenses: Our general and administrative expenses decreased by $206,100, or 1.46%, to $13,937,900 for the year ended December 31, 2021 from $14,144,000 for the year ended December 31, 2020. This decrease was primarily due to reduced stock compensation expenses, offset by increases in professional services fees, personnel, and recruiting costs.

• Net Loss: Our net loss increased to $25,588,700 during the year ended December 31, 2021 compared to $19,200,200 during the year ended December 31, 2020.

Recent Business Highlights:

ALEXIS (Gamma Delta CAR-T cell Platform) Research & Development:

• Developed an innovative and highly efficient process that improves the manufacturing of our cell therapy candidates, making it more space-efficient and cost-effective. We believe that this will significantly reduce the costs of CAR-T cell manufacturing, providing a competitive market advantage.
• Successfully tested a prototype variant of the ALEXIS manufacturing process that leverages the potential of pooled donors' cells. This is a necessary step to building a proprietary bank of precursor cells for the manufacturing of our ALEXIS product line. A donor cell bank is expected to ensure a high degree of homogeneity and consistency of our drug products, and at the same time to improve the resilience of our supply chain.
• Continued progress towards a scalable and retrovirus-free process for the delivery of recombinant genes into T cells. This is an important step towards the deployment of our proprietary non-viral cell engineering system.

Key Hires in Research & Development, Clinical Translational Medicine and Clinical Trial Preparation:

• The Company added new hires across the organization, specifically augmenting research & development, clinical translational medicine and clinical trial preparation capabilities. This represents a headcount total of nearly 60 employees, which is an increase from 19 as of December 31, 2020.

cGMP Manufacturing:

• We have completed approximately 90% of our in-house current Good Manufacturing Practices (cGMP) facility expansion and redesign.

DIAMOND®AI 2.0 Platform for Drug Discovery and Development is Completed:

• The Company developed and made operational a completely revised version of its proprietary platform for identification and vetting of immunotherapy targets. Diamond AI 2.0 was developed by Kiromic's in-house bioinformatics team and includes:
  • Enhanced and updated existing models to provide more accurate predictions of therapy target efficacy;
  • A modular, containerized architecture to support rapid addition of new algorithms, scientific methods, and therapy designs;
  • Integrated data mining components to provide a seamless workflow from identification of cancer-specific surface protein regions through to vetted immunotherapy targets;
  • Proteomic validation of transcript targets;
  • An additional 300+ million data points were added to the DIAMOND database in Q4 2021, which included proteomic data covering and extending the range of cancer types; and
  • Approximately 600 million data points were added in 2021, representing a 50% data point increase from 2020.
