Clinical Program Overview

Prexigebersen Phase 2 Clinical Trial – Bio-Path’s Phase 2 clinical trial for the treatment of AML is comprised of three cohorts of patients and treatments, each separately approvable by the FDA as a new indication. The first two cohorts are treating patients with the triple combination of prexigebersen, decitabine and venetoclax. The first cohort includes untreated AML patients, and the second cohort includes relapsed/refractory AML patients. Finally, the third cohort is treating relapsed/refractory AML patients who are venetoclax-resistant or intolerant with the two-drug combination of prexigebersen and decitabine. Outcomes for these older patients who are unable to receive intensive chemotherapy due to the challenging side effect profile, remain suboptimal with a median survival of only 5 to 10 months. As previously reported, Bio-Path identified two patients who have demonstrated continued treatment durability. These patients have each received over 15 treatment cycles and remain in complete remission.

Bio-Path expects to utilize an advisory panel of AML experts to assist in the design of the final clinical development plans through potential FDA approval. Other significant milestones expected during 2025 include the completion of Cohort 2 and an interim analysis for Cohort 3.

Phase 1/1b Clinical Trial in BP1001-A in Advanced Solid Tumors – A Phase 1/1b clinical trial of BP1001-A in patients with advanced or recurrent solid tumors, including ovarian and uterine, pancreatic and breast cancer, is ongoing. BP1001-A is a modified product candidate that incorporates the same drug substance as prexigebersen but has a slightly modified formulation designed to enhance nanoparticle properties. The Phase 1 study has advanced to the second, higher dose level and the first patient in the second dose cohort continued experiencing a positive response which may signal that this analog of prexigebersen has potential as a new treatment for advanced solid tumors. The patient continues to be doing well after failing extensive chemotherapy and surgical treatment for gynecologic cancer, demonstrating a 15% reduction in her primary tumor through ten cycles of treatment. Moreover, it appears that these positive outcomes may have contributed to allowing her to continue with rigorous exercise and improved quality of life. Completion of the second and third dosing cohorts are expected later this year.

The Phase 1b portion of the study is expected to commence after successful completion of the three BP1001-A monotherapy dose level cohorts and is intended to assess the safety and efficacy of BP1001-A in combination with paclitaxel in patients with recurrent ovarian or endometrial tumors. Phase 1b studies are also expected to be initiated in combination with gemcitabine in Stage 4 pancreatic cancer and combination therapy in breast cancer.

Phase 1/1b Clinical Trial in BP1002 in Relapsed/Refractory AML – A Phase 1/1b clinical trial for BP1002 to treat relapsed/refractory AML patients, including venetoclax-resistant patients, is ongoing. BP1002 targets the protein Bcl-2, which is responsible for driving cell survival in up to 60% of all cancers. Venetoclax treats AML patients by blocking the activity of the Bcl-2 protein in AML patients. However, over time patients become resistant to venetoclax. BP1002 treats the Bcl-2 target by blocking the cell’s ability to produce Bcl-2 and could provide benefit for these venetoclax resistant patients. AML patients that fail frontline venetoclax-based therapy have very poor prognosis with median overall survival of less than three months. The first dose cohort consisted of a starting dose of 20 mg/m2, the second dose cohort of 40 mg/m2 and there were no dose limiting toxicities. The third dosing cohort of 60 mg/m2 has been completed and the fourth dosing cohort of 90 mg/m2 is open for enrollment. Enrollment in the third dosing cohort closed faster than expected which Bio-Path believes reflects the need for additional treatment options.

Prexigebersen as Potential Treatment for Obesity in Type 2 Diabetes Patients – BP1001-A downregulates Grb2 expression to increase insulin sensitivity and helps lower blood glucose level in Type 2 diabetes patients. Scientific evidence suggests that by downregulating Grb2 expression, BP1001-A could help lower blood glucose levels by affecting insulin signaling. Bio-Path conducted preclinical studies that confirmed the effectiveness of BP1001-A in affecting insulin signaling and its potential efficacy as a therapeutic treatment for obese patients who have Type 2 diabetes. In May, the Company reported the achievement of a third milestone from preclinical studies of BP1001-A that provide additional support for its potential as a treatment for obesity. These studies showed BP1001-A rescues the decrease in AKT activity in liver cells and prevents cells from becoming insulin resistant, confirming its potential as a treatment for obesity and related metabolic diseases in Type 2 diabetes patients. In 2025, Bio-Path expects to complete preclinical testing and to file an Investigational New Drug (IND) application.

The single study finished enrollment of 47 patients with patients treated with Plinabulin, pembrolizumab and docetaxel on day 1 of each cycle until disease progression or intolerable severe adverse events. All patients progressed on PD-1/L1 inhibitors, including 78% who received pembrolizumab. Of the 47 patients, the median age was at 67 ranging from 44 to 83; 80.9% were male and 19.1% were female; 72.3% were current or former smokers. Histology included 63.8% patients with non-squamous cell carcinoma and 36.2% with squamous cell carcinoma. The median follow-up was 12.7 months. As of the data cut-off date of May 16, 2025, there are patients still responding to the therapy; therefore, the final data will be updated. The key results at the database lock are summarized below.

Median Progression-Free Survival (PFS):8 months — nearly double the 3.7 months seen with current standard of care (SOC) docetaxel1
Confirmed Objective Response Rate (ORR):2% — higher than the 12.8% seen with SOC docetaxel1
Disease Control Rate (DCR: PR + SD > 4 months):3% — indicating clinical benefit majority of patients who progressed on prior PD-1/L1 inhibitors
Median Duration of Response (DoR):2 months
6-Month PFS Rate:56%
15-Month Overall Survival (OS) Rate:78% (median OS not yet reached) – longer than median OS of 11.8 months for SOC docetaxel1
The combination was well tolerated. 1% of patients experienced grade 3 or higher treatment-related adverse effects, including GI side effects of 14.9% and transient hypertension of 14.9%. There were no treatment-related deaths.
"These promising Phase 2 results reinforce Plinabulin’s potential as a first-in-class therapy that addresses one of the most urgent challenges in oncology—acquired resistance to checkpoint inhibitors," said Dr. Lan Huang, PhD, Co-Founder, Chairman and CEO of BeyondSpring.

"By restoring immune sensitivity and improving progression-free survival, disease control rate and overall survival, Plinabulin opens a new therapeutic path for the more than 60% of patients who stop responding to PD-1/L1 therapies. We are encouraged by these data and committed to advancing Plinabulin in combination strategies to meet critical unmet needs in lung cancer and beyond."

A New Potential Pathway to Re-Sensitize Tumors to Immunotherapy
Immune checkpoint inhibitor (ICI)-based regimens have remained as the standard of care for first-line treatment of NSCLC, but over 60% patients could progress from ICI2. "Acquired resistance" to ICI could be caused by "T cell exhaustion" or "antigen presenting cell pathway mutation"2. Once progressed, it is not recommended to continue using ICI monotherapy. This underscores a substantial unmet need for more effective treatment options.

With over 700 cancer patients treated with good tolerability, Plinabulin is a first-in-class, late-stage, differentiated tubulin binder that activates GEF-H1, triggering dendritic cell (DC) maturation and T cell activation, and reduce chemotherapy induced neutropenia3,4,5. This dual innate and adaptive immune mechanism has demonstrated Plinabulin’s strong potential to reverse "acquired resistance to ICI" and to enhance the efficacy and tolerability of both PD-1/L1 inhibitors and chemotherapy-based regimens.

"This patient population—those who relapse after checkpoint inhibitors—faces a grim outlook with limited options," said Dr. Mengzhao Wang, Principal Investigator and Chief of Respiratory and Critical Care Medicine at Peking Union Medical College Hospital. "Second- and third-line NSCLC with no actionable driver mutation after progression of ICIs is a critical unmet medical need, with no new agent approval in the last decade. The current SOC docetaxel, approved 25 years ago, has limited efficacy and over 40% severe neutropenia. With Plinabulin’s benefit in significantly reducing severe neutropenia of docetaxel in a number of studies, this promising Phase 2 efficacy data suggests the triple combination may provide both efficacy and safety benefit in a meaningful way. We are encouraged and look forward to further study."
