Roche announces data at EHA2021 reinforcing efficacy of Venclexta/Venclyxto combinations in chronic lymphocytic leukaemia and acute myeloid leukaemia

On June 11, 2021 Roche (SIX: RO, ROG; OTCQX: RHHBY) reported the latest data from three pivotal phase III studies of Venclexta/Venclyxto (venetoclax) – CLL14, MURANO and VIALE-A – to be presented at the European Hematology Association (EHA) (Free EHA Whitepaper) Virtual Congress, June 9-17 (EHA2021) (Press release, Hoffmann-La Roche, JUN 11, 2021, View Source [SID1234583877]). Long-term follow-up data from the CLL14 and MURANO studies support the primary analysis of Venclexta/Venclyxto in chronic lymphocytic leukaemia (CLL) and the possibility of tailoring treatment approaches based on genetic risk factors. Furthermore, the latest research shows the potential of minimal residual disease (MRD) as a key measure of disease response in CLL and acute myeloid leukaemia (AML).

"The data from these Venclexta/Venclyxto combinations support our continued commitment to provide valuable therapeutic options for patients with hard-to-treat blood cancers," said Levi Garraway, M.D., Ph.D., Roche’s Chief Medical Officer and Head of Global Product Development. "These data also advance our understanding of minimal residual disease, which we believe is a useful endpoint that may help identify patients more quickly who are in need of additional treatment."

Four-year follow-up analysis of the phase III CLL14 study
This four-year post-hoc analysis of investigator-assessed progression-free survival (PFS) had a median follow-up of 52.4 months (interquartile range: 49.5-56.2 months). The fixed treatment duration (12 months) study indicated that the chemotherapy-free Venclexta/Venclyxto plus Gazyva/Gazyvaro (obinutuzumab) regimen had an estimated PFS rate of 74.0% vs 35.4% for Gazyva/Gazyvaro plus chlorambucil. Importantly, the time to next treatment (TTNT) was significantly longer among patients treated with the Venclexta/Venclyxto plus Gazyva/Gazyvaro regimen versus the comparator (four-year TTNT 81.1% vs 59.9%; HR 0.46, 95% CI [0.32-0.65], p<0.0001).1

Furthermore, 30 months after the end of treatment, 26.9% of the Venclexta/Venclyxto-treated patients still had undetectable MRD (uMRD) compared with 3.2% of those treated with the comparator.1 Undetectable MRD, sometimes referred to as MRD-negativity, means that no cancer cells could be detected using a specific and highly sensitive test, and is defined as less than one cancer cell in 10,000 leukocytes.4 Undetectable MRD is emerging as a measure of disease response that may be useful to consider in treatment decision-making.

Common grade 3-4 adverse events with Venclexta/Venclyxto and Gazyva/Gazyvaro at 28 months follow-up were low white blood cell count and infections.5

Substudy from the phase III MURANO study
Results from this substudy suggested that increased prevalence of certain unfavourable genetic risk factors negatively impacted the MRD response of patients who were retreated with Venclexta/Venclyxto plus MabThera/Rituxan (rituximab) after progression on treatment with that regimen. These data indicate the potential to tailor treatment approaches for patients with previously treated CLL based on genetic risk factors.2

Post-hoc analysis of the phase III VIALE-A study
Additionally, a post-hoc analysis from the phase III VIALE-A study suggested the value of continued research to understand the role of MRD monitoring in AML. In the analysis, patients who achieved a composite complete remission and uMRD following treatment with Venclexta/Venclyxto and azacitidine, a hypomethylating agent, had improved survival outcomes compared with those who were MRD-positive following treatment. The 12-month estimates for duration of response, overall survival and event-free survival for both groups are listed below:

Achieved composite complete remission and uMRD (MRD<10-3) Did not achieve composite complete remission and uMRD (MRD≥10-3)
Duration of response 81.2% (95% CI 69.3-88.9) 46.6% (95% CI 35.6-56.8)
Overall survival 94.0% (95% CI 84.7-97.7) 67.9% (95% CI 57.6-76.2)
Event-free survival 83.2% (95% CI 71.6-90.3) 45.4% (95% CI 35.2-55.0)
Adverse events of grade ≥3 (MRD<10-3/MRD≥10-3) were febrile neutropenia (50%/43%), neutropenia (50%/35%), and thrombocytopenia (44%/44%), similar to the overall population.3

Roche is collaborating with regulatory authorities and others in the industry to advance understanding of MRD. The company continues to investigate Venclexta/Venclyxto in a robust clinical development programme, including in the phase III CRISTALLO trial in previously untreated CLL, which uses MRD as a primary endpoint.

Venclexta/Venclyxto is approved in the US and EU in combination with MabThera/Rituxan for the treatment of adult patients with CLL who have received at least one prior therapy; in combination with Gazyva/Gazyvaro for the treatment of adult patients with previously untreated CLL; and as a monotherapy for the treatment of CLL in the presence of 17p deletion or TP53 mutation in people who are unsuitable for or have failed a B-cell receptor pathway inhibitor.

Venclexta is also approved in the US in combination with azacitidine, decitabine, or low dose cytarabine for the treatment of newly diagnosed AML in adults 75 years or older, or who have comorbidities that preclude use of intensive induction chemotherapy. In the EU, Venclyxto is approved in combination with a hypomethylating agent for the treatment of adult patients with newly diagnosed AML who are ineligible for intensive chemotherapy.

About the CLL14 study
CLL14 [NCT02242942] is a randomised phase III study evaluating the combination of fixed-duration Venclexta/Venclyxto (venetoclax) plus Gazyva/Gazyvaro (obinutuzumab) compared to Gazyva/Gazyvaro plus chlorambucil in adult patients with previously untreated chronic lymphocytic leukaemia (CLL) and co-existing medical conditions. Four hundred and thirty-two patients with previously untreated CLL were randomly assigned to receive either a 12-month duration of Venclexta/Venclyxto alongside six-month duration of Gazyva/Gazyvaro (Arm A) or six-month duration of Gazyva/Gazyvaro alongside 12-month duration of chlorambucil (Arm B). Arm A started with an initial dosing of Gazyva/Gazyvaro followed by a five-week Venclexta/Venclyxto dose ramp-up to help reduce the risk of tumour burden. The primary endpoint of the study is investigator-assessed progression-free survival (PFS). Secondary endpoints included PFS assessed by independent review committee, minimal residual disease status, overall response rate, complete response rate, and safety. The CLL14 study is being conducted in cooperation with the German CLL Study Group, headed by Michael Hallek, M.D., University of Cologne.

About the MURANO study
MURANO [NCT02005471] is a phase III open-label, international, multicentre, randomised study evaluating the efficacy and safety of fixed-duration Venclexta/Venclyxto (venetoclax) in combination with MabThera/Rituxan (rituximab) compared to bendamustine in combination with MabThera/Rituxan (BR). All treatments were of fixed duration. Following a five-week dose ramp-up schedule for Venclexta/Venclyxto, patients on the Venclexta/Venclyxto plus MabThera/Rituxan arm received six cycles of Venclexta/Venclyxto plus MabThera/Rituxan followed by Venclexta/Venclyxto monotherapy for up to two years total. The study included 389 patients with chronic lymphocytic leukaemia (CLL), with or without 17p deletion, who had been previously treated with at least one line of therapy. A substudy from 2018 onward enrolled 34 relapsed or refractory CLL patients who progressed after initial treatment to receive Venclexta/Venclyxto plus MabThera/Rituxan as retreatment (n=25) or who crossed over from the BR arm (n=9). The primary endpoint of the study was progression-free survival. Secondary endpoints included overall survival, overall response rate and complete response rate (with or without complete blood count recovery).

About the VIALE-A study
VIALE-A [NCT02993523] is a phase III, randomised, double-blind, placebo-controlled multicentre study evaluating the efficacy and safety of Venclexta/Venclyxto (venetoclax) plus azacitidine, a hypomethylating agent, compared to placebo with azacitidine, in 431 people with previously untreated acute myeloid leukaemia who are ineligible for intensive chemotherapy. Two-thirds of patients (n=286) received 400 mg Venclexta/Venclyxto daily, in combination with azacitidine, and the remaining patients (n=145) received placebo tablets in combination with azacitidine. Patients enrolled in the study had a range of mutational subtypes, including IDH1/2 and FLT3. VIALE-A met its primary and key secondary endpoints.

About Venclexta/Venclyxto
Venclexta/Venclyxto (venetoclax) is a first-in-class targeted medicine designed to selectively bind and inhibit the B-cell lymphoma-2 (BCL-2) protein. In some blood cancers and other tumours, BCL-2 builds up and prevents cancer cells from dying or self-destructing, a process called apoptosis. Venclexta/Venclyxto blocks the BCL-2 protein and works to restore the process of apoptosis.

Venclexta/Venclyxto is being developed by AbbVie and Roche. It is jointly commercialised by AbbVie and Genentech, a member of the Roche group, in the US and commercialised by AbbVie outside of the US. Together, the companies are committed to research with Venclexta/Venclyxto, which is currently being studied in clinical trials across several types of blood cancers.

In the US, Venclexta has been granted five Breakthrough Therapy Designations by the U.S. Food and Drug Administration: one for previously untreated chronic lymphocytic leukaemia (CLL), two for relapsed or refractory CLL and two for previously untreated acute myeloid leukaemia.

Curis Announces Positive Updated Data from Ongoing Phase 1/2 Study of CA-4948 Monotherapy in Patients with Relapsed or Refractory Acute Myeloid Leukemia and Myelodysplastic Syndromes

On June 11, 2021 Curis, Inc. (NASDAQ: CRIS), a biotechnology company focused on the development of innovative therapeutics for the treatment of cancer, reported updated data from its ongoing Phase 1/2 open-label, single arm, dose escalation and expansion trial of CA-4948, a novel, small molecule IRAK4 kinase inhibitor, in patients with acute myeloid leukemia (AML) or high-risk myelodysplastic syndromes (MDS) at the European Hematology Association (EHA) (Free EHA Whitepaper) 2021 Virtual Congress (EHA) (Free EHA Whitepaper) (Press release, Curis, JUN 11, 2021, View Source [SID1234583875]).

"As we have observed increasingly mature sets of data, we continue to be pleased by the steady progression of clinical activity demonstrated by CA-4948 monotherapy in this historically difficult-to-treat late-line population," said James Dentzer, President and Chief Executive Officer of Curis. "We believe these updated data further support the growing body of evidence that CA-4948’s anti-cancer activity continues to deepen the longer patients remain on drug, which is enabled by its safety and durability profile to date. Further, after backfilling patient cohorts and evaluating additional data after the April 30, 2021 cut-off date for today’s presentation, we have concluded 300mg BID is the optimal dose to take into Phase 2 studies."

Mr. Dentzer added, "We are especially pleased with the outcomes seen to date for patients with spliceosome or FLT3 mutations. All three patients with a spliceosome mutation achieved an objective response. The FLT3 patient also achieved an objective response and, after two cycles of CA-4948, the patient’s FLT3 mutation was found to be completely eradicated. While these are early days, and we have a limited set of patient data, we are very encouraged about the potential CA-4948 may have to become a disease-modifying alternative for these late-line patients, where no approved therapies currently exist."

Mr. Dentzer continued, "In addition to the updated clinical data presented today, we are also excited by the preclinical combination synergy data announced, demonstrating that CA-4948 increases anti-cancer activity in AML cell lines resistant to clinically relevant concentrations of azacitidine and venetoclax, as well as synergistic antileukemic activity in combination with venetoclax and azacitidine. We look forward to initiating dosing in the Phase 1/2 combination study of CA-4948 plus azacitidine and CA-4948 plus venetoclax in patients with R/R AML and MDS later this year."

"As a clinician for patients with high-risk MDS or AML, I am acutely aware of the challenges of these diseases and the limitations of existing treatments. I continue to be very encouraged by the data coming out of this study," said Dr. Guillermo Garcia-Manero, Chief of the Section of Myelodysplastic Syndromes within the Department of Leukemia at The University of Texas MD Anderson Cancer Center and a lead investigator in the study. "This is a late-line population, in which patients have few options following repeated treatment failures and as a result, have deeply damaged and dysfunctional marrow, which severely limits their odds of hematologic recovery. Having an effective, non-myelosuppressive drug that does not further damage their already fragile marrow is of critical importance. The fact that some hematologic recovery has been observed and appears to continue while patients remain on therapy is an indication that CA-4948 may have the potential to provide, for the first time, a well-tolerated and clinically active treatment for this subset of heavily diseased patients."

The reported data are from Curis’s ongoing open-label, single arm Phase 1/2 dose escalation 3+3 study of orally administered CA-4948 monotherapy in adult patients with AML or high-risk MDS. A total of 22 patients (11 with high-risk MDS, 11 with AML) were enrolled across dose cohorts of 200 mg BID, 300 mg BID, 400 mg BID, and 500 mg BID. The primary objective of the study is to determine the maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D) for CA-4948 based on safety and tolerability, dose-limiting toxicities (DLT), and any biologic activity, pharmacokinetic (PK), and pharmacodynamic (PD) findings from the trial population. Additional objectives include characterization of CA-4948’s pharmacokinetic parameters and biomarker correlations.

Key findings from an oral presentation today at EHA (Free EHA Whitepaper) presented by Dr. Garcia-Manero from an April 30, 2021 cutoff in 17 evaluable patients (9 MDS and 8 AML), include:

Bone marrow blast reductions observed at all tested doses in 10 of 12 patients who were evaluable for bone marrow response (elevated blast count at baseline and at least one malignancy assessment following first cycle).
5 objective responses observed included:
1 patient experiencing a full hematologic recovery CR
1 patient with CRi with negative minimal residual disease
1 patient with partial response
2 patients with marrow CRs
3 patients had SF3B1 or U2AF1 spliceosome mutation and all 3 achieved marrow CR or better.
All patients with objective responses also saw signs of hematologic recovery.
Genomic analyses from multiple patients show disease modification by CA-4948:
DNA sequencing demonstrates disease modification with the reduction of cancer-associated variant allele frequency after CA-4948 treatment
RNA sequencing demonstrates disease modification with the reduction of long/short ratio of IRAK4 after CA-4948 treatment
No significant myeloid suppressive adverse events were observed.
Key findings from additional information included in today’s management’s KOL presentation:

An AML patient with spliceosome mutation SF3B1 who has experienced a durable objective response has been on study for over 8 months. In December 2020, this patient was reported as having a Marrow CR and has since improved to a CRi with negative minimal residual disease.
An AML patient with a FLT3 mutation, whose disease had relapsed after prior treatment with decitabine and venetoclax and was refractory to subsequent treatment with gilteritinib, experienced a partial response (90% decrease in marrow blast count, from 60% to 6%) as well as elimination of detectable FLT3 mutation based on genomic analysis post-treatment with CA-4948.
An AML patient with 4 prior lines of chemotherapy treatment showed reduction of IRAK4-L expression following CA-4948 treatment as well as a full recovery of hematologic parameters and has been on study for over 7 months.
Key findings in determining 300mg BID to be the Recommended Phase 2 Dose include:

Safety: No DLTs observed
PK/PD: PK exposure correlates with 98% target inhibition
Efficacy: 12 evaluable patients in the study had elevated blasts at baseline;
4 of these patients were dosed at 300mg BID;
All 4 patients achieved blast reductions, including CRi and negative MRD
Including additional patients enrolled after the April 30, 2021 cut-off at doses higher than the Recommended Phase 2 Dose, a total of 4 DLTs were observed:
400mg: 13% of patients experienced DLT (2 Grade 3 rhabdomyolysis)
500mg: 66% of patients experienced DLT (1 Grade 3 rhabdomyolysis and 1 Grade 3 syncope)
All three rhabdomyolysis cases were quickly detected by elevated CPK and resolved after dosing interruption; no cases involved renal dysfunction.
Key findings from a poster presentation today at EHA (Free EHA Whitepaper) of preclinical data in AML cell lines:

Combination with CA-4948 increased the antitumor effect of azacitidine
Combination with CA-4948 increased the antitumor effect of venetoclax
Combination with CA-4948 increased the antitumor effect of venetoclax + azacitidine
We believe synergistic activity observed in leukemia cells provides a rationale for clinical testing of CA-4948 + azacitidine, CA-4948 + venetoclax, and the triplet combination of all three agents together in patients with AML.
Webcast Event Information

Curis management will host a virtual KOL event today, June 11, 2021 at 8:00 am ET to discuss these results with Dr. Guillermo Garcia-Manero. To access the webcast, please visit the Events & Presentations section of the Curis website at www.curis.com.

About CA-4948

CA-4948 is an IRAK4 kinase inhibitor and IRAK4 plays an essential role in the toll-like receptor (TLR) and interleukin-1 receptor (IL-1R) signaling pathways, which are frequently dysregulated in patients with AML and MDS. Third parties have recently discovered that the long form of IRAK4 (IRAK4-L) is oncogenic and preferentially expressed in over half of patients with AML and MDS. The overexpression of IRAK4-L is believed to be driven by a variety of factors, including specific spliceosome mutations such as SF3B1 and U2AF1.

Celyad Oncology Presents Preliminary Data from Phase 1 IMMUNICY-1 Trial of shRNA-based Allogeneic CAR T Candidate CYAD-211 in Relapsed/Refractory Multiple Myeloma at the European Hematology Association Virtual Congress

On June 11, 2021 Celyad Oncology SA (Euronext & Nasdaq: CYAD), a clinical-stage biotechnology company focused on the discovery and development of chimeric antigen receptor T cell (CAR T) therapies for cancer, reported preliminary data from the Phase 1 IMMUNICY-1 trial of CYAD-211 for the treatment of relapsed/refractory multiple myeloma (r/r MM) patients were presented at the European Hematology Association (EHA) (Free EHA Whitepaper) 2021 Virtual Congress (Press release, Celyad, JUN 11, 2021, View Source [SID1234583874]).

Filippo Petti, Chief Executive Officer of Celyad Oncology, commented, "We believe the initial data presented today are meaningful beyond the demonstrated clinical activity of CYAD-211. This is the first clinical trial evaluating the potential of shRNA as an allogeneic technology to underpin off-the-shelf CAR T candidates for the treatment of cancer, and today’s data continue to demonstrate the potential value of non-gene edited technology to generate allogeneic CAR T cells. We are extremely encouraged by the cell kinetic, clinical activity and tolerability data for CYAD-211. As we work to establish shRNA as a platform for developing allogeneic CAR T therapies, these early data from the IMMUNICY-1 trial are key. In addition, we believe our future ability to employ multiple shRNAs in our CAR T candidates while leveraging our streamlined All-in-One Vector approach could be fundamental to the allogeneic CAR T landscape."

Dr. Sébastien Anguille, IMMUNICY-1 trial investigator and professor in the Division of Hematology of the Antwerp University Hospital said, "Even with great strides made in recent years, multiple myeloma remains largely incurable, creating a need for new therapeutic options. Unfortunately, most patients eventually relapse and we observe shorter duration and depth of responses to treatments over time. We are pleased with the encouraging initial data from the IMMUNICY-1 trial and we’re eager to move forward with higher doses and continue to evaluate CYAD-211 in treating myeloma patients."

CYAD-211 and IMMUNICY-1 Phase 1 Trial Update

Background:

CYAD-211 is an allogeneic CAR T candidate engineered to co-express a BCMA targeting chimeric antigen receptor and a single short hairpin RNA (shRNA), which interferes with the expression of the CD3ζ component of the T cell receptor complex.
IMMUNICY-1 is a first-in-human, open-label, dose-escalation Phase 1 trial to determine the recommended dose of CYAD-211 in patients with r/r MM following preconditioning with cyclophosphamide (300 mg/m²) and fludarabine (30 mg/m²) given three consecutive days.
The trial is designed to evaluate proof-of-concept that shRNA-mediated knockdown of the CD3ζ can generate allogeneic CAR T cells.
Safety and tolerability data:

Of the six patients dosed at the first two dose levels (30×106 and 100×106 cells per infusion):

No dose limiting toxicity (DLT), Graft-versus Host disease (GvHD) or CAR T-cell-related encephalopathy syndrome (CRES) were observed in the first two dose cohorts.
One cytokine release syndrome (CRS) Grade 1 (fever) requiring hospitalization occurred 10 days post CYAD-211 administration in patient 1 (dose level 1) who achieved a partial response (PR).
One patient experienced an anemia adverse event (Grade 3) and neutropenia (Grade 4) possibly related to CYAD-211.
Clinical activity:

Of the five evaluable patients at the first two dose levels (30×106 and 100×106 cells per infusion):

Two patients achieved a PR. Both patients were ‘triple-therapy exposed’ (previously treated with an immunomodulator (IMiD), a proteasome inhibitor and an anti-CD38 antibody).
The three additional patients had stable disease (SD).
Cell kinetics:

CYAD-211 cells were detected by PCR-based methods in all six patients from dose cohorts 1 and 2.
Cell engraftment was seen in all three patients at dose level 2 at a similar magnitude. In addition, preliminary data suggest that all patients in dose level 2 showed deep lymphodepletion. Across dose level 1, the depth of lymphodepletion appears to correlate with the degree of observed systemic CAR T engraftment.
Next steps:

Enrollment in dose cohort 3 (300×106 cells per infusion) is ongoing.
Additional clinical data from the dose escalation trial are expected during second half 2021.
shRNA technology platform to be highlighted at upcoming virtual R&D Day in Q3 2021.

BERGENBIO PRESENTS ENCOURAGING UPDATED PRELIMINARY DATA FROM PHASE II STUDY IN RELAPSED AML PATIENTS AT EHA VIRTUAL MEETING

On June 11, 2021 BerGenBio ASA (OSE:BGBIO), BerGenBio ASA (OSE: BGBIO), a clinical-stage biopharmaceutical company developing novel, selective AXL kinase inhibitors for severe unmet medical need, reported that it will present updated preliminary survival data from the ongoing Phase II study of bemcentinib (BGBC003) in combination with low dose cytarabine (LDAC) in elderly relapsed Acute Myeloid Leukaemia (AML) patients at the European Haematology Association (EHA) (Free EHA Whitepaper) 2021 Virtual Meeting, taking place from 9-17 June 2021 (Press release, BerGenBio, JUN 11, 2021, View Source [SID1234583872]).

An update will be provided from an expansion cohort of 27 relapsed/refractory AML patients, who were assessed to explore safety and efficacy together with translational analysis.

The data indicate that the combination of bemcentinib, a once-daily oral AXL-inhibitor and LDAC is efficacious and well tolerated in the elderly and unfit relapsed AML population. Durable responses were observed in the relapsed AML setting, with an overall response rate of 31% (5/16) and median overall survival of 13.3 months, currently still immature and potentially subject to change.

In a subset of eleven relapsed AML patients, who received two or more cycles of the combination, an increased clinical benefit was demonstrated; a CR/CRi rate of 36% (4/11) was observed, coupled with encouraging overall survival to date (median OS not reached at >16 months) with several subjects continuing on the study. In contrast, historic controls of LDAC monotherapy suggest CR/CRi rates of 13-17% with median survival rates of 4.1-5.6 months, as reported by Sarkozy et al. (2015) and Wei et al. (2020).

An in-depth translational research program to identify predictive molecular and biological factors associated with response is ongoing.

Ongoing dialogue continues with the FDA and EMA regulatory agencies to align on a pathway for a pivotal registration trial for the combination of bemcentinib and LDAC in relapsed elderly AML patients unfit for intensive chemotherapy.

Dr. Sonja Loges, Principal Investigator of the trial, commented: "We were impressed to see these positive responses in relapsed AML patients, for whom treatment options are very limited under the current standard of care. Interestingly, the first complete responses were reported at a relatively late stage in the trial, between week 13 and 15. These later onset responses could reflect the importance of AXL mechanisms in disease development as well as the potential immune promoting benefits of bemcentinib treatment. Further clinical investigation of this promising combination is therefore warranted."

Richard Godfrey, CEO of BerGenBio, commented: "We are very encouraged by this promising preliminary response and survival data from the combination of bemcentinib and LDAC in this patient population. Effective treatments with meaningful survival benefit for relapsed AML patients is acknowledged as a critical unmet medical need, this being a significant and rapidly growing patient population as the first line treatment options improve. We continue to work closely with the regulators in Europe and the US to align on the way forward to embark on late-stage pivotal trial of bemcentinib in this combination and patient population."

About AXL

AXL kinase is a cell membrane receptor and an essential mediator of the biological mechanisms underlying life-threatening diseases.

In COVID-19, AXL has two synergistic mechanisms of action, it acts a co-receptor to ACE2, to which the spike protein of the SARS-CoV-2 virus attaches and enters the host cell, and AXL expression is upregulated that leads to suppression of the Type 1 Interferon immune response by host cells and in their environment.

Research data confirms bemcentinib inhibits SARS-CoV-2 host cell entry and promotes the anti-viral Type I interferon response. Data from a Phase II in human clinical trial has shown that treatment with AXL inhibitor bemcentinib increased the rate ventilator free survival in hospitalised COVID-19 patients.

In cancer, increase in AXL expression has been linked to key mechanisms of drug resistance and immune escape by tumour cells, leading to aggressive metastatic cancers. AXL suppresses the body’s immune response to tumours and drives treatment failure across many cancers. High AXL expression defines a very poor prognosis subgroup in most cancers. AXL inhibitors, such as bemcentinib, therefore, have potential high value as monotherapy and as the cornerstone of cancer combination therapy, addressing significant unmet medical needs and multiple high-value market opportunities. Research has also shown that AXL mediates other aggressive diseases including fibrosis.

About Bemcentinib

Bemcentinib (formerly known as BGB324), is a potential first-in-class, potent and highly selective AXL inhibitor, currently in a broad phase II clinical development programme. It is administered as an oral capsule and taken once per day. Ongoing clinical trials are investigating bemcentinib in COVID-19, and multiple solid and haematological tumours, in combination with current and emerging therapies (including immunotherapies, targeted therapies and chemotherapy), and as a single agent. Bemcentinib targets and binds to the intracellular catalytic kinase domain of AXL receptor tyrosine kinase and inhibits its activity.
