The Phase 1 dose escalation trial is evaluating GTB-3650, GT Biopharma’s second-generation TriKE, for the treatment of relapsed or refractory (r/r) CD33 expressing hematologic malignancies. Cohorts 1 and 2 have now both been successfully completed and following the formal safety reviews, no safety or tolerability issues have been observed. This has allowed initiation of dosing in Cohort 3, with the first patient now having completed the first week of cycle 1.

Patients from Cohort 1 and Cohort 2 have shown encouraging early results indicative of GTB-3650’s ability to activate endogenous NK cells and induce NK cell expansion. Data from multiple blood biomarker assays from the first four patients show heightened immune activity. GT Biopharma plans on releasing initial Phase 1 results later in 2025 following completion of additional dose cohorts.

The trial plans to evaluate GTB-3650 in up to approximately 14 patients (seven cohorts) and GTB-3650 will be dosed in two-week blocks, two weeks on and two weeks off (defining a treatment cycle), for up to four months based on clinical benefit. The trial will assess safety, pharmacokinetics, pharmacodynamics, in vivo expansion of endogenous patient NK cells and clinical activity. More details can be found on clinicaltrials.gov with the identifier: NCT06594445.

On August 11, 2025 I-Mab (NASDAQ: IMAB) (the Company), a U.S.-based, global biotech company, focused on the development of precision immuno-oncology agents for the treatment of cancer, reported that enrollment in the planned Phase 1b dose expansion cohorts evaluating givastomig, a bispecific Claudin 18.2 x 4-1BB antibody, in combination with nivolumab and mFOLFOX6, has been completed ahead of expectations (Press release, I-Mab Biopharma, AUG 11, 2025, View Source [SID1234655069]).

The Phase 1b study (NCT04900818) is evaluating the safety, efficacy, pharmacokinetics (PK), and pharmacodynamics (PD) of givastomig, a potential best-in-class, Claudin 18.2 (CLDN18.2) x 4-1BB bispecific antibody, used in combination with nivolumab and mFOLFOX6, as first line therapy (1L) in patients with CLDN18.2-positive gastric cancers (≥1+ intensity in ≥1% of cells). The primary endpoint is safety. The study enrolled only patients in the U.S. The dose expansion cohorts of the study enrolled a total of 40 patients across two doses (8 mg/kg and 12 mg/kg).

"Our optimism in givastomig has been bolstered by the accelerated pace of enrollment in the Phase 1b trial and the ongoing enthusiasm of the study’s investigators. These observations highlight the unmet need for improved gastric cancer therapy, the oncology community’s growing interest in Claudin 18.2-directed therapies and its awareness of the givastomig clinical program. I am encouraged by the Phase 1b dose escalation data, and hopeful that givastomig can become a new treatment option for patients with Claudin 18.2-positive gastric cancers," said Phillip Dennis, MD, PhD, Chief Medical Officer of I-Mab. "I especially want to thank the patients, their families, investigators and study sites for their continued support for this program."

Data from the dose escalation cohorts of the study were presented on July 2, 2025 in a Mini Oral presentation at the European Society for Medical Oncology Gastrointestinal Cancers Congress (ESMO GI) 2025 in Barcelona, Spain, accessible here. The data showed that givastomig in combination with immunochemotherapy achieved an 83% (10/12) objective response rate (ORR) at the doses (8 mg/kg and 12 mg/kg) selected for dose expansion. Response onset was rapid, durable and deepened over time, with favorable overall safety. I-Mab hosted a virtual investor event on July 8, 2025 reviewing the Phase 1b dose escalation data (accessible for viewing here).

About Givastomig

Givastomig (TJ033721 / ABL111) is a bispecific antibody targeting Claudin 18.2 (CLDN18.2)-positive tumor cells. It conditionally activates T cells through the 4-1BB signaling pathway in the tumor microenvironment where CLDN18.2 is expressed. Givastomig is being developed for first line (1L) metastatic gastric cancers, with further potential in other solid tumors. In Phase 1 trials, givastomig has shown promising anti-tumor activity attributable to a potential synergistic effect of proximal interaction between CLDN18.2 on tumor cells and 4-1BB on T cells in the tumor microenvironment, while minimizing toxicities commonly seen with other 4-1BB agents.

An ongoing Phase 1b study is evaluating givastomig for the treatment of gastric cancer in the 1L setting in combination with standard of care, nivolumab (an anti-PD-1 checkpoint inhibitor) plus chemotherapy, in dose escalation (n=17) and dose expansion (n=40) cohorts. The study builds on positive Phase 1 monotherapy data.

Givastomig is being jointly developed through a global partnership with ABL Bio, in which I-Mab is the lead party and shares worldwide rights, excluding Greater China and South Korea, equally with ABL Bio.

On August 11, 2025 IO Biotech (Nasdaq: IOBT) reported topline results from the pivotal Phase 3 trial of its investigational, immune-modulatory, off-the-shelf therapeutic cancer vaccine, Cylembio (imsapepimut and etimupepimut, adjuvanted) (Press release, IO Biotech, AUG 11, 2025, View Source [SID1234655070]). The trial evaluated Cylembio in combination with Merck’s anti-PD-1 therapy, KEYTRUDA (pembrolizumab), vs. pembrolizumab alone as a first-line treatment in 407 patients with unresectable or metastatic (advanced) melanoma. In the study, Cylembio plus pembrolizumab demonstrated clinical improvement in progression free survival compared to pembrolizumab alone, but statistical significance was narrowly missed on the primary endpoint.

"In this study, we observed a highly encouraging improvement in progression free survival and consistent trend in overall survival in patients treated with Cylembio," said Mai-Britt Zocca, PhD, president and chief executive officer of IO Biotech. "The magnitude and durability of clinical effect observed consistently across subgroups supports our confidence in Cylembio and its potential as a treatment for advanced melanoma patients. We look forward to engaging with the FDA to determine a potential path to approval based on these data."

The randomized, open-label study enrolled 407 patients across more than 100 sites worldwide. Patients received either Cylembio in combination with pembrolizumab (n=203) or pembrolizumab alone (n=204). The primary endpoint was PFS as assessed by a blinded independent review committee per RECIST v1.1. The early and sustained separation of PFS curves demonstrated an improvement with a hazard ratio of 0.77 [95% CI: 0.58-1.00; p=0.056; threshold for significance p≤0.045]. Based on an intent-to-treat analysis, patients in the study treated with Cylembio in combination with pembrolizumab achieved 19.4 months of median progression free survival compared to 11.0 months in patients treated with pembrolizumab alone.

Although not yet mature, a trend toward an improvement in overall survival was also observed [HR 0.79 (95% CI: 0.57-1.10)]; the company expects OS to mature over the next six to nine months.

Improvement in PFS was achieved across virtually all subgroups, including those with poor prognostic factors, with a profound effect in patients with PD-L1 negative tumors treated with Cylembio plus pembrolizumab (n=67) compared to patients treated with pembrolizumab monotherapy (n=63), HR: 0.54 (CI 0.35-0.85) (nominal p=0.006), with mPFS of 16.6 months vs. 3.0 months, respectively. Additionally, in a post hoc analysis of patients enrolled in this study without prior anti-PD-1 treatment (n=371), patients treated with Cylembio plus pembrolizumab achieved improvement in PFS compared to patients treated with pembrolizumab monotherapy, HR: 0.74 (CI 0.56-0.98) (nominal p=0.037), with mPFS of 24.8 months vs. 11.0 months, respectively.

The combination was well tolerated, with no new safety signals observed. Injection site reactions, which were transient and resolved on treatment, were the most commonly reported adverse events in the combination arm, with 56% of patients receiving Cylembio plus pembrolizumab reporting an event.

"In this study, patients treated with Cylembio in combination with pembrolizumab have achieved the longest median PFS ever observed in a Phase 3 clinical study in advanced melanoma, and in the PD-L1 negative population, patients achieved a remarkable 16.6 months of median PFS, compared to 3.0 months in patients treated with pembrolizumab alone," said Omid Hamid, MD, Director, Clinical Research and Immunotherapy at The Angeles Clinic and Research Institute, A Cedars Sinai Affiliate. "The significant benefit seen across patients with poor prognostic factors, including PD-L1 negative patients, cannot be overlooked. Given the notable safety profile and the strong clinical effect observed with Cylembio, as well as the unmet need in advanced melanoma patients, Cylembio, if approved, has the potential to become a new standard of care for patients with advanced melanoma."

"These data show the potential of a therapeutic cancer vaccine in patients with metastatic melanoma," said Jessica Hassel, MD, Professor at the Department of Dermatology and National Center for Tumor Diseases at the University Hospital Heidelberg, Germany, and lead enrolling investigator for the Phase 3 trial. "We were thrilled to play such an important part in this study and to have had the ability to offer our patients an investigational therapy that potentially offers improvements in PFS while not adding significant systemic toxicity."

"Delaying progression and improving survival is the ultimate treatment goal for patients and although overall survival is not yet mature, the trend we are seeing in OS with separation of the curves is encouraging, with a consistent PFS clinical improvement and OS trend favoring the combination arm across virtually all subgroups, with no new safety signals or significant additional systemic toxicity," said Qasim Ahmad, MD, chief medical officer of IO Biotech. "We are deeply grateful to the patients for their participation in this study, as well as to investigators and study coordinators whose dedication and collaboration brings us one step closer to delivering a new treatment option to patients in need."

"Since reporting the positive outcome of our Phase 1/2 study (MM1636) in a similar patient population, we have been eagerly awaiting these results supporting the activity of Cylembio combined with an anti-PD-1 in patients with advanced melanoma," said Inge Marie Svane, MD, PhD, Professor, Director of the National Center for Cancer Immune Therapy (CCIT) at the Copenhagen University Hospital, Herlev and Principal Investigator in the Phase 3 trial. "These data provide evidence that a therapeutic cancer vaccine can improve progression free survival in patients with metastatic disease."

Based on these results, IO Biotech plans to meet with the United States (US) Food and Drug Administration (FDA) this fall to discuss the totality of data and determine next steps for submission of a Biologics License Application (BLA) for the treatment of advanced melanoma. Additionally, the company plans to present more detailed results from the IOB-013 study at an upcoming medical meeting.

Second Quarter 2025 Highlights

XPOVIO Commercial Performance

U.S. net product revenue was $29.7 million in the second quarter of 2025 compared to $28.0 million in the second quarter of 2024.
Demand for XPOVIO was consistent in the second quarter of 2025 compared to the second quarter of 2024, with the community setting continuing to drive approximately 60% of overall net product revenue.
Expanded global patient access for selinexor is translating into growth in royalty revenue from Menarini, Antengene and other international partners. Royalty revenue increased 28% to $1.6 million in the second quarter of 2025 compared to the second quarter of 2024.
Research and Development (R&D) Highlights

Myelofibrosis

The Phase 3 SENTRY trial (XPORT-MF-034; NCT04562389) is nearing full enrollment and the Company expects new patient screening will be closed this week. SENTRY is targeting 350 patients for enrollment and is evaluating 60 mg once-weekly selinexor in combination with ruxolitinib compared to ruxolitinib plus placebo. The preliminary baseline characteristics for patients enrolled in SENTRY are representative of the intended patient population. In addition, preliminary blinded aggregate safety data from the first 61 patients with a median follow-up of greater than 12 months may suggest improvements in both hematologic and non-hematologic treatment emergent adverse events as compared to the Phase 1 data evaluating selinexor 60 mg weekly in combination with standard of care ruxolitinib in JAKi-naïve myelofibrosis patients, as well as historical ruxolitinib monotherapy data. The Company cautions that the preliminary baseline characteristics and preliminary blinded aggregate safety data may not be reflective of the actual top-line data.
Presented data from the XPORT-MF-035 (NCT04562870) Phase 2, randomized, open-label trial of selinexor versus physician’s-choice in hard-to-treat patients with heavily pretreated myelofibrosis (N=24) at the European Hematology Association (EHA) (Free EHA Whitepaper) 2025 Congress. The data suggest the potential for single-agent clinical activity with selinexor, including spleen volume reduction, symptom improvement, hemoglobin stabilization, and evidence of disease modification. A copy of the poster that was presented at EHA (Free EHA Whitepaper), titled "A Study to Evaluate Single-Agent Selinexor Versus Physician’s Choice in Participants With Previously Treated Myelofibrosis" is available under "Publications and Presentations" in the Investor section of the Company’s website.
The Company continues to enroll JAKi-naïve myelofibrosis patients with moderate thrombocytopenia (defined as having platelet counts between 50,000 and 100,000) in the selinexor 60 mg cohort of the Phase 2 SENTRY-2 trial (XPORT-MF-044; NCT05980806). The Company plans to amend the protocol for SENTRY-2 to also include patients with platelet counts above 100,000, which will expand the number of patients that are eligible to participate in the trial. Approximately 10% to 15% of patients with myelofibrosis have platelet counts between 50,000 and 100,0001. The Company expects to report top-line data from all patients in the 60 mg cohort with at least 24 weeks of follow-up in 2026.

Endometrial Cancer

Enrollment continues in the Phase 3 XPORT-EC-042 (NCT05611931) trial evaluating selinexor as a maintenance-only therapy following systemic therapy versus placebo in patients with TP53 wild-type advanced or recurrent endometrial cancer.
Multiple Myeloma

Enrollment of approximately 120 patients in the Phase 3 XPORT-MM-031 trial (EMN29; NCT05028348) was completed in the fourth quarter of 2024. The trial is being conducted in collaboration with the European Myeloma Network and is evaluating the all-oral combination of selinexor 40 mg, pomalidomide and dexamethasone (SPd40) in patients with previously treated multiple myeloma who received an anti-CD38 in their immediate prior line of therapy.
Anticipated Catalysts and Operational Objectives

Myelofibrosis

The Company expects new patient screening will be closed for the Phase 3 SENTRY trial this week with top-line data expected in March 2026.
Multiple Myeloma

Maintain the Company’s commercial foundation in the increasingly competitive multiple myeloma marketplace and drive increased XPOVIO revenues.
Continue to support global launches by our partners following regulatory and reimbursement approvals for selinexor in ex-U.S. territories.
Continue to follow patients that are enrolled in the Phase 3 XPORT-MM-031 (EMN29) trial. The Company expects to report top-line data from this event-driven trial in the first half of 2026.
Endometrial Cancer

Continue to enroll patients into the Phase 3 XPORT-EC-042 trial of selinexor as a maintenance monotherapy for patients with TP53 wild-type advanced or recurrent endometrial cancer. The Company expects to report top-line data from this event-driven trial in mid-2026.
2025 Financial Outlook

Based on its current operating plans, Karyopharm expects the following for full year 2025:

Total revenue to be in the range of $140 million to $155 million. Total revenue consists of U.S. XPOVIO net product revenue and license, royalty and milestone revenue earned from partners.
U.S. XPOVIO net product revenue to be in the range of $110 million to $120 million.
R&D and selling, general and administrative (SG&A) expenses to be in the range of $240 million to $250 million.
The Company expects its existing liquidity, including the revenue it expects to generate from XPOVIO net product sales and its license agreements, will be sufficient to fund its planned operations to the maturity of its senior convertible notes due October 2025 (Remaining 2025 Notes). Excluding the $24.5 million Remaining 2025 Notes maturity and its $25.0 million minimum liquidity covenant, the Company expects it would have sufficient liquidity to fund planned operations into January 2026. The Company, with the assistance of its advisors, including its financial advisor Centerview Partners, is exploring potential financing and strategic alternatives to enhance liquidity and maximize value.
Second Quarter 2025 Financial Results

Total revenue: Total revenue for the second quarter of 2025 was $37.9 million, compared to $42.8 million for the second quarter of 2024.

Net product revenue: Net product revenue for the second quarter of 2025 was $29.7 million, compared to $28.0 million for the second quarter of 2024.

License and other revenue: License and other revenue for the second quarter of 2025 was $8.2 million, compared to $14.8 million for the second quarter of 2024. The decrease was primarily attributable to $6.0 million of non-recurring license-related revenue recognized during the second quarter of 2024.

Cost of sales: Cost of sales for the second quarter of 2025 was $1.1 million, compared to $1.5 million for the second quarter of 2024. Cost of sales reflects the costs of XPOVIO units sold and the costs of products sold to our partners.

R&D expenses: R&D expenses for the second quarter of 2025 were $32.8 million, compared to $38.4 million for the second quarter of 2024. The decrease was due to a reduction in personnel costs and stock-based compensation costs primarily due to a reduction in headcount and contractors, coupled with lower clinical trial and related costs due to the reduced scope of our Phase 3 multiple myeloma trial.

SG&A expenses: SG&A expenses for the second quarter of 2025 were $28.5 million, compared to $31.1 million for the second quarter of 2024. The decrease was primarily due to the realization of previously implemented cost reduction initiatives.

Interest income: Interest income for the second quarter of 2025 was $0.6 million, compared to $1.9 million for the second quarter of 2024. The decrease was due to a lower cash and investments balance quarter-over-quarter.

Interest expense: Interest expense for the second quarter of 2025 was $11.2 million, compared to $8.9 million for the second quarter of 2024. The increase was related to a full quarter of interest on the term loan and convertible debt that were issued in the second quarter of 2024.

Gain on Extinguishment of Debt and Other (expense) income: Other expense for the second quarter of 2025 was $2.2 million compared to $14.3 million of other income for the second quarter of 2024. The change is attributable to recurring non-cash fair value remeasurements related to the refinancing transactions that were completed in the second quarter of 2024. The refinancing transactions also resulted in a $44.7 million gain on extinguishment of debt during the second quarter of 2024.

Net (loss) income: Karyopharm reported a net loss of $37.3 million, or $4.32 net loss per basic and diluted share, for the second quarter of 2025, compared to net income of $23.8 million, or $2.26 net income per basic share and $2.97 net loss per diluted share, for the second quarter of 2024. Net (loss) income included non-cash stock-based compensation expense of $3.8 million and $5.4 million for the second quarters of 2025 and 2024, respectively.

Cash position: Cash, cash equivalents, restricted cash and investments as of June 30, 2025 totaled $52.0 million, compared to $109.1 million as of December 31, 2024.

On August 10, 2025 Akeso, Inc. (9926.HK) ("Akeso" or the "Company") reported that the first patient has been dosed in its multicenter, randomized, double-blind Phase III study (AK112-311/HARMONi-9), evaluating ivonescimab, a first-in-class PD-1/VEGF bispecific antibody developed by Akeso, in small cell lung cancer (SCLC) (Press release, Akeso Biopharma, AUG 10, 2025, View Source [SID1234655048]). This study is designed to assess the efficacy and safety of ivonescimab as consolidation therapy in patients with limited-stage small cell lung cancer (LS-SCLC) who have not experienced progression following standard concurrent chemoradiotherapy (cCRT).

AK112-311/HARMONi-9 study is the eighth registrational Phase III clinical trial for ivonescimab in lung cancer (including three international multicenter studies). The initiation of this trial further expands ivonescimab’s therapeutic coverage across key lung cancer indications and different lines of treatment. As the world’s first PD-1/VEGF bispecific antibody, ivonescimab is driving significant transformation in the overall lung cancer treatment landscape and holds the potential to fundamentally improve global lung cancer therapies.

Small cell lung cancer (SCLC) represents approximately 15% of all lung cancers and is known for its aggressive nature, early metastasis, and poor prognosis. Around 30% of patients are diagnosed at the limited stage (LS-SCLC), with over 80% being ineligible for surgical intervention. The current standard of care involves concurrent or sequential chemoradiotherapy (cCRT/sCRT), where most patients face recurrence or develop drug resistance. To date, only one PD-L1 therapy has been approved for consolidation treatment for LS-SCLC, highlighting the significant unmet clinical need of this difficult to treat cancer.

In previous studies focused on extensive-stage SCLC (ES-SCLC), ivonescimab has demonstrated its ability to prolong progression-free survival (PFS), combining the synergistic benefits of PD-1/L1 inhibitors and anti-angiogenic agents. Ivonescimab is a cornerstone in Akeso’s "IO 2.0" strategy, and Akeso has already initiated a series of Phase III and Phase II clinical trials investigating ivonescimab as a first-line treatment across multiple cancer indications. The initiation of a Phase III study of ivonescimab for LS-SCLC is another key step in extending Akeso’s "IO 2.0" approach to earlier stages of lung cancer.
