"These patents will strengthen our global intellectual property portfolio, providing protection for therapeutic combinations, including our ongoing Acclaim-3 clinical trial."

These patents build upon Genprex’s existing intellectual property framework. The Company already holds granted patents for the use of REQORSA in combination with PD-L1 antibodies in the U.S. and Korea, with a pending grant in Australia. Genprex also holds granted patents for the combination of REQORSA and PD-1 antibodies in the U.S., Japan, Mexico, Russia, Australia, Chile, China, Singapore and Europe. The Japanese and European patents will further solidify the global intellectual property landscape surrounding Genprex’s lead drug candidate in oncology.

About Acclaim-3

Acclaim-3 is a Phase 1/2 clinical trial evaluating the combination of REQORSA and Genentech’s Tecentriq (atezolizumab) as maintenance therapy in patients with extensive stage small cell lung cancer (ES-SCLC) who are candidates for maintenance therapy after receiving Tecentriq and chemotherapy as standard of care initial treatment. In this study, patients will be treated with REQORSA and Tecentriq until disease progression or unacceptable toxicity is experienced.

The Phase 2 expansion study follows the successful completion of the Phase 1 dose escalation portion of the study, which showed REQORSA was generally well tolerated. There were no dose limiting toxicities, and in Acclaim-3, the Phase 2 patients are receiving the same dose of REQORSA as patients in the Phase 2 portion of Acclaim-1.

The Phase 2 expansion portion is expected to enroll approximately 50 patients. The primary endpoint of the Phase 2 portion is to determine the 18-week progression-free survival rate from the time of the start of maintenance therapy with REQORSA and Tecentriq in patients with ES-SCLC. Patients will also be followed for survival. Genprex’s team plans to conduct an interim analysis after the 25th patient enrolled and treated reaches 18 weeks of follow up. The Company expects to complete enrollment of the first 25 patients for interim analysis in the Phase 2 expansion portion of the study in the first half of 2026 and expects the interim analysis in the second half of 2026. The Acclaim-3 clinical trial is supported by FDA Fast Track Designation and Orphan Drug Designation.

On February 23, 2026 C4 Therapeutics, Inc. (C4T) (Nasdaq: CCCC), a clinical-stage biopharmaceutical company dedicated to advancing targeted protein degradation science, reported that the first patient has been dosed in the Phase 2 MOMENTUM trial evaluating cemsidomide in combination with dexamethasone for the treatment of relapsed/refractory multiple myeloma (RRMM).

"Initiating the Phase 2 MOMENTUM trial, which builds upon the compelling anti-myeloma activity and differentiated safety profile established in the Phase 1 trial, is a critical step for cemsidomide to become a foundational therapy for multiple myeloma patients, who are in need of a safe, oral, and convenient treatment option," said Len Reyno, chief medical officer of C4 Therapeutics. "With this milestone accomplished, we are also on track to initiate the Phase 1b trial of cemsidomide in combination with elranatamab in the second quarter, as we continue to advance our regulatory strategy that could deliver two accelerated approval paths in multiple myeloma."

The Phase 2 MOMENTUM trial is an open-label, single-arm, multicenter study to assess anti-myeloma activity and further characterize the safety, tolerability, pharmacokinetics and pharmacodynamics of cemsidomide, an oral IKZF1/3 degrader, in combination with dexamethasone in RRMM patients for the fourth line or later. The trial will enroll approximately 100 patients to evaluate cemsidomide at the 100 µg dose level. Cemsidomide is administered with a daily dosing schedule of 14 days on and 14 days off, and dexamethasone is dosed once a week. The primary endpoint is the overall response rate per the International Myeloma Working Group response criteria as assessed by an independent review committee. Secondary endpoints will evaluate a range of additional safety and efficacy measures.

The Phase 2 MOMENTUM trial is part of a broader development strategy for cemsidomide, which also includes a Phase 1b study of cemsidomide in combination with elranatamab (ELREXFIO). Elranatamab is an FDA-approved B-cell maturation antigen CD3 targeted bispecific antibody. Together, these trials support cemsidomide’s use across multiple lines of treatment.

ANTICIPATED UPCOMING MILESTONES

Phase 1b trial of cemsidomide in combination with elranatamab is on track to initiate in Q2 2026.
Further analysis of the completed Phase 1 trial of cemsidomide in combination with dexamethasone is expected in mid-2026.
Enrollment for Phase 2 MOMENTUM trial is expected to be completed in Q1 2027.
About Cemsidomide
Cemsidomide is an investigational, orally bioavailable molecular glue degrader (MonoDAC degrader) of IKZF1/3, transcription factors foundational to multiple myeloma biology. Data from the Phase 1 trial, which has completed enrollment, show cemsidomide’s differentiated safety and tolerability profile and potentially class-leading anti-myeloma activity that support the potential for durable outcomes.

About the MOMENTUM Trial
MOMENTUM (Multi-center trial Of cemsidoMidE iN relapsed/refracTory mUltiple Myeloma) is a Phase 2, open-label, single-arm, study to evaluate efficacy, safety, pharmacokinetics and pharmacodynamics of cemsidomide in combination with dexamethasone in patients with relapsed/refractory multiple myeloma. Data from the Phase 1 trial identified 100 µg as the recommended Phase 2 dose. The primary endpoint is overall response rate per International Myeloma Working Group response criteria, as assessed by an independent review committee. Approximately 100 patients who have received at least three prior anti-myeloma regimens that must have included an IKZF1/3 degrader, a proteasome inhibitor, an anti-CD38 antibody, and a T-cell engager or CAR-T therapy will be enrolled in the trial. More information is available at clinicaltrials.gov (NCT07284758).

About Cemsidomide in Combination With Elranatamab (ELREXFIO)
The Phase 1b trial is designed to evaluate the safety, tolerability and preliminary efficacy of cemsidomide in combination with elranatamab, an FDA-approved B-cell maturation antigen CD3 targeted bispecific antibody. The study will evaluate different cemsidomide dose levels (beginning with 75 µg, with the opportunity to simultaneously explore 50 µg and 100 µg) in patients who have received one to four prior lines of therapy, which must have consisted of at least one IKZF1/3 degrader. Exclusion criteria for patients include those who have received prior treatment with a BCMA-directed T-cell engager or BCMA-directed CAR-T therapy. More information is available at clinicaltrials.gov (NCT07280013).

About Multiple Myeloma
Multiple myeloma (MM) is a rare blood cancer affecting plasma cells. Approximately 36,000 people in the United States are diagnosed with MM each year. Approved IKZF1/3 degraders remain foundational therapies across lines of MM treatment. Despite advances, including immune-directed approaches, most patients ultimately relapse, underscoring a growing need for new therapeutics options that continue to leverage IKZF1/3 degradation to drive myeloma cell death and T-cell activation.
