This Phase 1/2 trial evaluated the safety and efficacy of an oral administration regimen of decitabine-cedazuridine paired with venetoclax in 101 adult AML patients who were ineligible for first-line induction chemotherapy.
Study results
Complete remission (CR), which was the primary endpoint of the study, was 46.5%, and CR with incomplete hematologic recovery rates was 63.4%. Median time to CR was 2.4 months. Median CR duration was not reached; among patients who achieved it, 80% maintained that status at 6 months and 75.3% at 12 months. Median OS was 15.5 months.

98% of patients reported treatment-emergent adverse events of grade 3 or higher*, most commonly febrile neutropenia (49.5%), anemia (38.6%) and neutropenia (35.6%). The 30- and 60-day mortality rates were 3% and 9%, respectively.

About acute myeloid leukemia (AML)
AML is a disease in which the proliferation of leukemia cells inhibits the normal production of blood in the bone marrow. It is the most common type of acute leukemia in adults, and its incidence increases with age. There is a need for less toxic treatment methods for elderly patients who have difficulty receiving first-line induction chemotherapy.
About decitabine-cedazuridine
This combination is the world’s first oral DNA methylation inhibitor combined with a novel metabolic inhibitor that inhibits the breakdown of decitabine when administered orally.
It was approved in the U.S. and Canada in 2020 for the indications of myelodysplastic syndromes (MDS) and chronic myelomonocytic leukemia (CMML), and in Europe in 2023 for the indication of AML.

Evaxion doses first patient in extension of phase 2 trial exploring the full potential of AI-designed personalized cancer vaccine EVX-01

On May 22, 2925 Evaxion A/S (NASDAQ: EVAX) ("Evaxion"), a clinical-stage TechBio company specializing in developing AI-Immunology powered vaccines, has dosed the first patient in its one-year extension of the ongoing phase 2 trial with its lead asset EVX-01 (Press release, Evaxion Biotech, MAY 22, 2025, View Source [SID1234653291]). Designed with Evaxion’s AI-Immunology platform, EVX-01 is a personalized cancer vaccine currently being evaluated as a treatment for advanced melanoma (skin cancer).

The extension will further explore the full potential of EVX-01 as a possible new and innovative treatment of advanced melanoma, particularly its long-term clinical and immune benefits. The trial extension involves minimal cost as trial sites are running and the vaccine product has already been produced.

Having completed the initial two-year treatment, the first patient in the extension of the trial has now received the first additional dose of EVX-01. Patients entering the one-year extension of the trial will in total receive two additional EVX-01 doses as monotherapy.

In the first two years of the trial, EVX-01 was administered in combination with standard anti-PD-1 therapy (checkpoint inhibitors). With checkpoint inhibitor treatment restricted to a two-year duration, the extension phase provides an opportunity to evaluate the benefits of EVX-01 monotherapy. This could position EVX-01 as a potential standalone treatment for advanced melanoma.

"Extending the trial allows us to explore EVX-01’s potential beyond its combination use with checkpoint inhibitors. By studying EVX-01 as a monotherapy, we aim to assess the independent effects of EVX-01, including its induced immune response and clinical outcome. Given that checkpoint inhibitor therapy is not approved beyond two years of treatment, this additional EVX-01 treatment option could offer a meaningful option for patients", says Birgitte Rønø, Chief Scientific Officer of Evaxion.

EVX-01 is designed with Evaxion’s AI-Immunology platform and tailored to target the unique tumor profile and immune characteristics of each individual patient. It engages the patient’s immune system to fight off cancer by mounting a targeted response against tumors.

The phase 2 trial investigates EVX-01 in combination with MSD’s (Merck & Co., Inc., Rahway, NJ, USA) anti-PD-1 therapy, KEYTRUDA (pembrolizumab) in patients with advanced melanoma (skin cancer). Each patient enrolled in the trial has received a unique vaccine designed and manufactured based on their individual biology. KEYTRUDA is a registered trademark of Merck Sharp & Dohme LLC, a subsidiary of Merck & Co., Inc., Rahway, NJ, USA.

Convincing one-year phase 2 data
Initially planned to run for two years, the trial remains on track to yield two-year data for presentation in the second half of 2025. Convincing interim one-year data from the trial was presented at the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress in September 2024. Data demonstrated a 69% Overall Response Rate, reduction in tumor target lesions in 15 out of 16 patients, and a positive correlation between the AI-Immunology platform predictions and immune responses induced by the individual neoantigens in the EVX-01 vaccine (p=0.00013).

Further, 80% of EVX-01’s vaccine targets triggered a targeted immune response, as presented at American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting in April 2025. This number compares very favorably to what is seen with other approaches.

About EVX-01
EVX-01 is a personalized peptide-based cancer vaccine intended for first-line treatment of multiple advanced solid cancers. It is Evaxion’s lead clinical asset.

EVX-01 is a personalized therapy designed with our AI-Immunology platform and is tailored to target the unique tumor profile and immune characteristics of each patient. It engages the patient’s immune system to fight off cancer by mounting a targeted response against tumors.

In the completed phase 1/2a clinical trial (NCT03715985), assessing EVX-01 in combination with a PD-1 inhibitor, eight of twelve metastatic melanoma patients (67%) had objective clinical responses, with two complete and six partial responses.

In addition, vaccine-induced T cells were detected in all patients and a significant correlation between clinical response and the AI-Immunology predictions was observed, underlining the predictive power of the platform.

New Two-year Follow-up of Genentech’s Columvi Extends Overall Survival in Relapsed or Refractory Diffuse Large B-cell Lymphoma Patients

On May 22, 2025 Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), reported two-year follow-up data from the Phase III STARGLO study. After a median follow-up of 24.7 months, data showed a 40% improvement in overall survival (OS) for patients treated with Columvi (glofitamab-gxbm) in combination with gemcitabine and oxaliplatin (GemOx) and median OS was not reached, compared to 13.5 months for Rituxan (rituximab) plus GemOx (R-GemOx) (Press release, Genentech, MAY 22, 2025, View Source [SID1234653350]). These updated data continue to demonstrate the statistically significant and clinically meaningful survival benefit of this off-the-shelf, fixed-duration Columvi combination for people with relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL) who have received at least one prior line of therapy and are not candidates for autologous stem cell transplant (ASCT). Data will be presented in an oral session at the 61st American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper), May 30 – June 3, 2025.

"We are encouraged that the two-year follow-up data for Columvi reinforces its potential to extend the lives of many patients where prognosis has historically been poor," said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. "These findings demonstrate the potential lasting benefits of early and effective treatment initiation with a bispecific antibody for people with relapsed or refractory disease."

"When cancer comes back or doesn’t respond to treatment, it’s devastating for patients with DLBCL given the aggressive nature of the disease," said Haifaa Abdulhaq, M.D., professor, University of California San Francisco (UCSF), director of Hematology, UCSF Fresno. "In my community practice, I’ve seen the potential of this Columvi combination to help patients start treatment quickly – providing lasting remissions and more time without ongoing therapy."

The benefit across key secondary endpoints, including progression-free survival (PFS) and complete remission (CR), was maintained for patients treated with the Columvi combination. There was a 59% reduction in the risk of disease progression or death (hazard ratio =0.41, 95% confidence interval: 0.29–0.58) and more than twice as many patients sustained a CR (58.5% vs. 25.3%). Among patients with a CR at the end of the treatment period, 89% were alive and 82% had maintained remission one year after treatment. Safety of the combination remained unchanged from the previous analysis and was consistent with the known safety profiles of the individual medicines. Patients received a higher median number of cycles of the Columvi combination (11 versus 4), due to disease progression in the R-GemOx arm. A higher rate of adverse events (AEs) was observed with the Columvi regimen. One of the most common AEs was cytokine release syndrome, which was generally low grade.

Given the wide adoption of global treatment guidelines in real-world clinical practice, there are no biological or clinical differences in DLBCL management worldwide. While second-line therapies have advanced, DLBCL can progress rapidly and many people are not candidates for, cannot tolerate, or do not have access to latest therapies. There is an urgent need for treatments that are rapidly available upon a diagnosis of relapse, that can manage the disease and improve long-term outcomes.

Based on the STARGLO data, this Columvi combination is approved in more than 30 countries for people with R/R DLBCL who are not candidates for ASCT, including countries throughout the EU. Columvi in combination with GemOx was added to the National Comprehensive Cancer Network Clinical Practice Guidelines in Oncology (NCCN Guidelines) as an NCCN category 1 preferred recommendation for the treatment of people with second-line DLBCL who are not intended to proceed to transplant.† Columvi monotherapy has been approved for use in R/R DLBCL after two or more prior lines of therapy in more than 60 countries worldwide.

Columvi is part of Genentech’s industry-leading CD20xCD3 bispecific antibody program. Together with the clinical development of off-the-shelf allogeneic CAR T-therapies, Genentech aims to provide tailored treatment options that suit the diverse needs, preferences, and experiences of people with blood cancers and healthcare systems.

About the STARGLO study

The STARGLO study [GO41944; NCT04408638] is a Phase III, multicenter, open-label, randomized study evaluating the efficacy and safety of Columvi (glofitamab-gxbm) in combination with gemcitabine plus oxaliplatin (GemOx) versus Rituxan (rituximab) in combination with GemOx in patients with relapsed or refractory diffuse large B-cell lymphoma who have received at least one prior line of therapy and who are not candidates for autologous stem cell transplant, or who have received two or more prior lines of therapy. Preclinical research indicated an increased antitumor effect when combining Columvi with GemOx over GemOx alone, so the STARGLO study was initiated to further explore the potential complementary effects of the treatment combination. Outcome measures include overall survival (primary endpoint), progression-free survival, complete response rate, objective response rate, duration of objective response (secondary endpoints), and safety and tolerability.

About Columvi (glofitamab-gxbm)

Columvi is a CD20xCD3 T-cell engaging bispecific antibody designed to target CD3 on the surface of T cells and CD20 on the surface of B cells. Columvi was designed with a novel 2:1 structural format. This T-cell engaging bispecific antibody is engineered to have one region that binds to CD3, a protein on T cells, a type of immune cell, and two regions that bind to CD20, a protein on B cells, which can be healthy or malignant. This dual-targeting brings the T cell in close proximity to the B cell, activating the release of cancer cell-killing proteins from the T cell. Columvi is part of Genentech’s broad and industry-leading CD20xCD3 T-cell-engaging bispecific antibody clinical development program, which aims to provide tailored treatment options that suit the diverse needs, preferences, and experiences of people with blood cancers and healthcare systems. Genentech is investigating Columvi as a monotherapy and in combination with other medicines for the treatment of diffuse large B-cell lymphoma (DLBCL) and mantle cell lymphoma.

As part of Genentech’s efforts to elevate treatment standards in the earlier stages of DLBCL, where there is the best opportunity to improve long-term outcomes and prevent relapse, Columvi is also being investigated in combination with other medicines in previously untreated DLBCL in the Phase III SKYGLO study [GO44145; NCT06047080].

About Diffuse Large B-Cell Lymphoma

Diffuse large B-cell lymphoma (DLBCL) is an aggressive (fast-growing) blood cancer and is the most common form of non-Hodgkin’s lymphoma in the U.S. Approximately 160,000 people worldwide are diagnosed with DLBCL each year, with comparable incidence rates across regions. Medical practices, including pathological classification, diagnosis, staging, initial treatment and relapse management, are similarly approached worldwide. While it is generally responsive to treatment in the frontline, as many as 40% of people will relapse or have refractory disease, at which time salvage therapy options are limited and survival is short. Improving treatments earlier in the course of the disease and providing much-needed alternative options could help to improve long-term outcomes.

Columvi U.S. Indication

Columvi (glofitamab-gxbm) is a prescription medicine to treat adults with certain types of diffuse large B-cell lymphoma (DLBCL) or large B-cell lymphoma (LBCL) that has come back (relapsed) or that did not respond to previous treatment (refractory), and who have received 2 or more prior treatments for their cancer.

It is not known if Columvi is safe and effective in children.

The conditional approval of Columvi is based on response rate and durability of response. There are ongoing studies to establish how well the drug works.

What is the most important information I should know about Columvi?

Columvi can cause Cytokine Release Syndrome (CRS), a serious side effect that is common during treatment with Columvi, and can also be serious and lead to death.

Call your healthcare provider or get emergency medical help right away if you develop any signs or symptoms of CRS, including:

fever of 100.4°F (38°C) or higher
chills or shaking
fast or irregular heartbeat
dizziness or light-headedness
trouble breathing
shortness of breath
Due to the risk of CRS, you will receive Columvi on a "step-up dosing schedule".

A single dose of a medicine called obinutuzumab will be given to you on the first day of your first treatment cycle (Day 1 of Cycle 1).
You will start the Columvi step-up dosing schedule a week after the obinutuzumab dose. The step-up dosing schedule is when you receive smaller "step-up" doses of Columvi on Day 8 and Day 15 of Cycle 1. This is to help reduce your risk of CRS. You should be hospitalized during your infusion and for 24 hours after receiving the first step-up dose on Day 8. You should be hospitalized during your infusion and for 24 hours after receiving the second step-up dose on Day 15 if you experienced CRS during the first step-up dose.
You will receive your first full dose of Columvi a week after the second step-up dose (this will be Day 1 of Cycle 2).
If your dose of Columvi is delayed for any reason, you may need to repeat the "step-up dosing schedule".
If you had more than mild CRS with your previous dose of Columvi, you should be hospitalized during and for 24 hours after receiving your next dose of Columvi.
Before each dose of Columvi, you will receive medicines to help reduce your risk of CRS and infusion-related reactions.
Your healthcare provider will monitor you for CRS during treatment with Columvi and may treat you in a hospital if you develop signs and symptoms of CRS. Your healthcare provider may temporarily stop or completely stop your treatment with Columvi if you have severe side effects.

Carry the Columvi Patient Wallet Card with you at all times and show it to all of your healthcare providers. The Columvi Patient Wallet Card lists the signs and symptoms of CRS you should get emergency medical help for right away.

Lacutamab was recently granted Breakthrough Therapy Designation by the U.S. Food and Drug Administration (FDA) for the treatment of Sézary syndrome, underscoring its potential to address critical needs in advanced CTCL.

As of October 17, 2024, data cut-off, lacutamab demonstrated compelling and sustained clinical activity in heavily pretreated patients, with a global ORR of 42.9% for SS and 19.6% for MF. With longer follow-up, we observed improved median duration of response of 25.6 months in SS and 13.8 months in MF, highlighting the durability of responses in these challenging indications1.

In addition, lacutamab was very well tolerated supporting the strong rationale for further investigations in combination beyond CTCL, especially in combination with other anti-lymphoma agents in peripheral T-cell lymphomas (PTCL).

"Patients with advanced mycosis fungoides and Sézary syndrome often face a poor prognosis and limited treatment options after multiple prior lines of therapy," said Prof. Pierluigi Porcu, Director, Division of Hematologic Malignancies and Hematopoietic Stem Cell Transplantation, Sidney Kimmel Cancer Center, Jefferson Health, Philadelphia and principal investigator of the TELLOMAK trial. "The durability and depth of responses observed with lacutamab in this study are highly promising and represent a significant advancement for this patient population."

"The long-term follow-up data from the TELLOMAK clinical study confirms lacutamab’s meaningful clinical benefit in Sézary syndrome and mycosis fungoides and were the basis of the FDA Breakthrough Therapy Designation. We are encouraged by these results and are actively preparing a Phase 3 trial in collaboration with health authorities to bring this promising therapy to patients as swiftly as possible," added Dr Sonia Quaratino, Chief Medical Officer of Innate Pharma.

About Lacutamab

Lacutamab is a first-in-class anti-KIR3DL2 humanized cytotoxicity-inducing antibody that is currently in clinical trials for treatment of cutaneous T-cell lymphoma (CTCL), an orphan disease, and peripheral T cell lymphoma (PTCL). Rare cutaneous lymphoma of T lymphocytes have a poor prognosis with few efficacious and safe therapeutic options at advanced stages.

KIR3DL2 is an inhibitory receptor of the KIR family, expressed by approximately 65% of patients across all CTCL subtypes and expressed by up to 90% of patients with certain aggressive CTCL subtypes, in particular, Sézary syndrome. KIR3DL2 is expressed in up to 50% of patients with mycosis fungoides and peripheral T-cell lymphoma (PTCL). It has a restricted expression on normal tissues.

Lacutamab has been granted European Medicines Agency (EMA) PRIME designation, and the US Food and Drug Administration (FDA) granted Fast Track designation for the treatment of patients with relapsed or refractory Sézary syndrome who have received at least two prior systemic therapies. Lacutamab is granted orphan drug status in the European Union and the United States for the treatment of CTCL. Lacutamab has received Breakthrough Therapy Designation from the FDA.

About TELLOMAK

TELLOMAK (NCT03902184) is a global, open-label, multi-cohort Phase 2 clinical trial in patients with Sézary syndrome and mycosis fungoides (MF) in the United States and Europe. Specifically:

Cohort 1: lacutamab being evaluated as a single agent in approximately 60 patients with Sézary syndrome who have received at least two prior systemic therapies, including mogamulizumab. The Sézary syndrome cohort of the study could enable the registration of lacutamab in this indication.
Cohort 2: lacutamab being evaluated as a single agent in patients with MF that express KIR3DL2, as determined at baseline with a Simon 2-stage design.
Cohort 3: lacutamab being evaluated as a single agent in patients with MF that do not express KIR3DL2, as determined at baseline, with a Simon-2 stage design.
All comers: lacutamab being evaluated as a single agent in patients with both KIR3DL2 expressing and non-expressing MF to explore the correlation between the level of KIR3DL2 expression and treatment outcomes utilizing a formalin-fixed paraffin embedded (FFPE) assay under development as a companion diagnostic.
The trial is fully enrolled. The primary endpoint of the trial is objective global response rate. Key secondary endpoints are progression-free survival, duration of response, overall survival, quality of life, pharmacokinetics and immunogenicity and adverse events.
