Citius Oncology, Inc. Announces First Reported Revenue Following Successful Launch of LYMPHIR™

Company reports $3.9 million in revenue generated from initial sales in December 2025 and provides first fiscal quarter 2026 financial results

CRANFORD, N.J., Feb. 13, 2026 /PRNewswire/ — Citius Oncology, Inc. (“Citius Oncology”) (Nasdaq: CTOR), the oncology-focused subsidiary of Citius Pharmaceuticals, Inc. (“Citius Pharma”) (Nasdaq: CTXR), today reported financial results for the fiscal first quarter ended December 31, 2025, and provided a business update.

“The first quarter of fiscal 2026 marked a pivotal inflection point for Citius Oncology with the successful U.S. commercial launch of LYMPHIR and the Company’s first reported revenue,” said Leonard Mazur, Chairman and Chief Executive Officer of Citius Oncology and Citius Pharma. “This transition from a development-stage organization to a commercial oncology company reflects years of deliberate preparation and coordination across our clinical, manufacturing, distribution, and commercial infrastructure.”

“With initial distributor sales complete nationwide, we are now focused on accelerating physician adoption and expanding patient access. Since the start of calendar 2026, physicians have begun to initiate patients on LYMPHIR, and our formulary review efforts are progressing as planned. We are preparing to expand our field presence to support a highly concentrated prescriber base in this rare cancer setting, supported by an advanced AI-enabled commercial platform designed to drive efficient market penetration,” added Mazur.

“As LYMPHIR is now broadly available, we remain focused on execution, capital management, and evaluating strategic opportunities that we believe can meaningfully enhance long-term shareholder value,” concluded Mazur.

Business Highlights and Subsequent Developments

• Initiated U.S. commercial launch of LYMPHIR™ (denileukin diftitox-cxdl) in December 2025, establishing Citius Oncology as a commercial-stage oncology company with an FDA-approved IL-2 receptor-directed immunotherapy for adult patients with relapsed or refractory Stage I–III cutaneous T-cell lymphoma (CTCL) following at least one prior systemic therapy;
