Company is Activating Additional Clinical Trial Sites Across the U.S.

Kiromic BioPharma, Inc. (OTC PINK: KRBP) (“Kiromic” or the “Company”), a clinical-stage, fully-integrated biotherapeutics company using its proprietary DIAMOND^® artificial intelligence and data mining platform to develop cell therapies with a focus on immuno-oncology, announces the Deltacel^™ Phase 1 Clinical Trial is now recruiting patients at the Beverly Hills Cancer Center (BHCC). The study will evaluate Deltacel^™ (KB-GDT-01), Kiromic’s allogeneic, off-the-shelf, Gamma Delta T-cell (GDT) therapy, in patients with metastatic non-small cell lung cancer (NSCLC).

The Company continues to engage additional clinical trial sites across the U.S, and will provide updates as additional sites are activated, and as patient recruitment starts at those locations.

The Phase 1 trial, titled “Safety Study for a Gamma Delta T Cell Product Used With Low Dose Radiotherapy in Patients With Stage 4 Metastatic NSCLC” (ID# NCT06069570), expects to enroll up to 48 patients. In this open-label, two-part trial, patients with stage 4 NSCLC will receive two intravenous infusions of Deltacel along with four courses of low-dose, localized radiation, over a 10-day period. The primary objective of the study is to evaluate the safety of Deltacel in combination with low-dose radiation; the secondary outcome measures are objective response, progression-free survival, overall survival, time to progression, time to treatment response, and disease control rates.

“We are delighted to announce the start of patient recruitment in our first clinical trial, and we look forward to working with BHCC and the other prestigious trial sites we will be activating across the U.S. Importantly, we are on target to dose our first patient, and we expect to have early tolerability and safety data from this patient available by the end of 2023,” stated Pietro Bersani, Chief Executive Officer of Kiromic BioPharma. “We plan to assess preliminary efficacy by end of January 2024, and complete the dose-escalation portion of the study by the second half of 2024, at which point we expect to have sufficient evidence supporting the tolerability and the efficacy of Deltacel™. These are crucial steps forward as we advance our goal to bring a transformative new treatment to patients with advanced NSCLC.”

About Deltacel^™ (KB-GDT-01)

Deltacel (KB-GDT-01) is an investigational gamma delta T-cell (GDT) therapy currently in the Deltacel-01 Phase 1 trial for the treatment of non–small cell lung cancer. An allogeneic product consisting of unmodified, donor-derived gamma delta T cells, Deltacel is Kiromic BioPharma’s lead candidate in its GDT platform. Deltacel is designed to exploit the natural potency of GDT cells to target solid cancers, with an initial focus on NSCLC, the most prevalent type of lung cancer and representing about 80% to 85% of lung cancer cases. Data from two preclinical studies demonstrated Deltacel’s favorable safety and efficacy profile when it was combined with low-dose radiation.
