Kiromic Biopharma Stock Price, News & Analysis

Kiromic BioPharma, Inc. (OTCQB: KRBP) is a clinical-stage, fully integrated biotherapeutics company focused on immuno-oncology. According to the company’s public statements, Kiromic is developing a multi-indication allogeneic cell therapy platform that uses the natural potency of gamma delta T-cells (GDT cells) to target solid tumors. The company reports that it uses its proprietary DIAMOND® artificial intelligence (AI) 2.0 target discovery engine to identify novel targets for cell therapies. Kiromic maintains offices in Houston, Texas and its common stock trades on the OTCQB under the symbol KRBP.

Business focus and therapeutic platform

Kiromic describes itself as a clinical-stage company developing cell therapies for patients with advanced cancers. Its work centers on allogeneic, off-the-shelf gamma delta T-cell therapies. Allogeneic products, as described by the company, consist of unmodified, donor-derived gamma delta T cells that are manufactured for use in multiple patients rather than being derived from each individual patient.

The company’s lead product candidate is Deltacel™ (KB-GDT-01), which Kiromic identifies as the leading candidate in its GDT platform. Deltacel is described as an investigational gamma delta T-cell therapy designed to exploit the natural potency of GDT cells to target solid cancers, with an initial clinical focus on stage 4 metastatic or locally advanced non-small cell lung cancer (NSCLC) that has failed to respond to standard therapies. Kiromic cites preclinical studies in which Deltacel combined with low-dose radiation demonstrated a favorable safety and efficacy profile.

Deltacel-01 Phase 1 clinical trial

Kiromic is conducting an open-label Phase 1 clinical trial titled “Phase 1 Trial Evaluating the Safety and Tolerability of Gamma Delta T Cell Infusions in Combination With Low Dose Radiotherapy in Subjects With Stage 4 Metastatic Non-Small Cell Lung Cancer” (NCT06069570). In this study, patients with advanced NSCLC who have failed to respond to standard therapies receive intravenous infusions of Deltacel™ combined with courses of low-dose, localized radiation over a defined treatment period.

The company states that the primary objective of the Deltacel-01 trial is to evaluate safety and tolerability. Secondary measurements include objective response, progression-free survival (PFS), overall survival, time to progression, time to treatment response and disease control rates. Kiromic has reported interim clinical observations such as partial responses, tumor volume reductions, stable disease, and progression-free survival durations in individual patients enrolled in the trial, as well as the absence of dose-limiting toxicities in early cohorts, based on data from its press releases.

Regulatory designations and clinical sites

Kiromic has announced that the U.S. Food and Drug Administration (FDA) granted Fast Track designation to Deltacel™ (KB-GDT-01) in combination with low-dose radiation therapy for the treatment of patients with metastatic NSCLC who have progressed on at least two lines of standard-of-care therapy, including platinum-based chemotherapy, immune checkpoint inhibitors and targeted therapy, with the goal of improving progression-free survival and overall survival. The company indicates that Deltacel is being evaluated in the Deltacel-01 Phase 1 study in patients with stage 4 NSCLC who have failed to respond to standard therapies.

Kiromic has also reported the activation of multiple clinical trial sites for Deltacel-01. These include the Beverly Hills Cancer Center, Clinical Research Advisors Koreatown (a satellite location of Beverly Hills Cancer Center), Texas Oncology in Tyler, Texas, Virginia Oncology Associates in Norfolk, Virginia, and the University of Arizona Cancer Center (UACC), which Kiromic notes is one of the NCI-Designated Comprehensive Cancer Centers in the United States. The company has described the progression of the trial into an expansion phase following a unanimous recommendation from the Deltacel-01 Safety Monitoring Committee after review of safety data from initial cohorts.

Use of DIAMOND® AI 2.0 platform

In its public communications, Kiromic states that it uses its proprietary DIAMOND® artificial intelligence (AI) 2.0 target discovery engine to discover novel targets for immuno-oncology and to develop and commercialize cell therapies. The company describes DIAMOND AI as a platform where data science meets target identification, with the stated aim of compressing the time and resources required to develop a live drug. This AI-driven approach is positioned by Kiromic as central to its strategy of building a multi-indication allogeneic cell therapy platform.

Historical and legacy focus

Earlier descriptions of Kiromic’s activities, such as the Polygon summary, reference a focus on cancer-associated biomarkers and small molecules, the development of clinical diagnostic tools for rapid detection of cancer-associated antigens, and the design of personalized, cancer-specific targeted immunotherapy strategies. These descriptions emphasize the company’s interest in both diagnostic and therapeutic applications aimed at earlier diagnosis, accurate monitoring of treatment response, and potentially improved patient outcomes. More recent company press releases emphasize the clinical-stage development of Deltacel and the gamma delta T-cell platform, indicating a strong focus on cell therapy-based immuno-oncology.

Industry classification and sector

Based on the provided classification, Kiromic operates within Research and Development in Biotechnology under the broader sector of Professional, Scientific, and Technical Services. As a clinical-stage biotherapeutics company, its activities are concentrated on early-stage clinical development, preclinical research, and target discovery in oncology, rather than on commercialized pharmaceutical products.

Stock and regulatory context

Kiromic’s common stock trades on the OTCQB market under the ticker symbol KRBP. The company has publicly disclosed interaction with the U.S. Securities and Exchange Commission (SEC), including a settlement of a previously disclosed SEC investigation related to the non-disclosure by prior executive management of clinical holds placed by the FDA on certain investigational new drug applications. Kiromic has stated that, in light of its self-reporting, remediation and cooperation, the SEC determined not to impose a civil penalty on the company and that there are no ongoing undertakings in connection with that settlement.
