"We recently reported the positive readout of several clinical trials that strongly validate our strategy to concentrate our efforts on evaluating bemcentinib to treat Non-Small Cell Lung Cancer patients harboring STK11 mutations," said Martin Olin, Chief Executive Officer of BerGenBio. "I would like to thank our shareholders for their support of the recent Rights Issue, providing gross proceeds of 250M NOK, allowing us to pursue the significant opportunity in STK11m NSCLC. We look forward to sharing initial data from our Phase 1a/2b trial in the second half of this year towards unlocking the value of bemcentinib in NSCLC."

Clinical Development

Bemcentinib

BerGenBio's lead compound, bemcentinib, is a potentially first-in-class, oral, highly selective inhibitor of the receptor tyrosine kinase AXL, which is expressed and activated in response to oxidative stress, inflammation, hypoxia and drug treatment, resulting in several deleterious effects in cancer and severe respiratory infections. Bemcentinib selectively inhibits AXL activation to prevent the progression of serious diseases through the modulation of resistance mechanisms and the adaptive immune system.

Bemcentinib is currently being developed in STK11 mutated NSCLC and severe respiratory infections. Its novel mechanisms of action and primary accumulation in the lungs uniquely position it to address these severe lung diseases.

Oncology: NSCLC

1L STK11m NSCLC (BGBC016)

The Company announced on March 9, 2023, that the first patient was enrolled in BGBC016, a global, open-label Phase 1b/2a trial designed to determine the safety, tolerability and efficacy of bemcentinib in combination with standard of care treatments in untreated advanced/metastatic non-squamous NSCLC patients with STK11 mutations and no actionable mutations.

The Phase 1b portion of the study is evaluating the safety and feasibility of three different doses of bemcentinib in combination with pembrolizumab and doublet chemotherapy in 1L advanced/metastatic non-squamous NSCLC patients, regardless of STK11 status. The Phase 2a expansion part will assess the safety and efficacy of up to two doses of bemcentinib in the same treatment combination in 1L advanced/metastatic non-squamous NSCLC patients with STK11 mutations.

A significant subgroup comprising approximately 20% (> 30,000 patients in US and EU5) of non-squamous NSCLC patients harbor STK11 mutations, which are associated with immunosuppression and poor prognosis with standard treatment in 1L NSCLC. Data suggests that STK11m NSCLC patients almost universally have AXL expression and activation in tumors and/or on immune cells, resulting in the development of drug resistance, immune evasion, and metastases.

The results of the BGBC008 (2L+ NSCLC, bemcentinib in combination with pembrolizumab) and BGBIL005 (2L+ NSCLC, bemcentinib in combination with docetaxel) trials provide clinical evidence of the anti-tumor effects of bemcentinib and its ability to modulate the tumor microenvironment to enhance the effects of immunotherapy and chemotherapy. We believe this provides strong support for the ongoing BGBC016 1L NSCLC trial in patients harboring STK11 mutations.

2L+ NSCLC Trial (BGBC008)

InFebruary 2023the Company announced topline data from the Phase 2 BGBC008 2L+ NSCLCtrial and provided additional results from pre-planned analyses after quarter end on May 15,2023. The trial enrolled 90 evaluable patients who received at least one prior line of therapy:chemotherapy, immunotherapy or the combination.

• A clinically meaningful survival benefit and evidence of disease control was demonstratedwithbemcentinibin combination with pembrolizumab regardless of prior therapy,providing a median overall survival (mOS) of 13.0 months (95% CI: 10.1, 16.7), medianprogression free survival (mPFS) of 6.2 months (95% CI: 4.6, 9.8), disease control rate(DCR) of 51.1% (95% CI: 40.3, 61.8) and overall response rate (ORR) of 11.1% (95% CI: 6.2,18.1).
• A significant (p-value < 0.05) and clinically meaningful improvement inmOSbased on AXLIHC tumor scores was observed. Patients with AXL score > 5 (46% of evaluable patients)achieved amOSof 14.8 months (95% CI: 12.4, 29.6) compared to patients with AXL < 5,who achieved amOSof 9.9 months (95% CI: 6.7, 17.4). In addition, patients with an AXL >5 had amPFSof 8.7 months (95% CI: 6.0, 14.8) compared to 4.6 months (95% CI: 2.7, 8.1)for patients with AXL < 5. The ORR for AXL > 5 was 21.9%.
• The observedmOSwas similar regardless of patient PD-L1 status.
• Treatment withbemcentinibin combination with pembrolizumab was well-tolerated.
• Pre-planned biomarker analyses of patients in BGBC008 indicate that the combination ofbemcentinib and pembrolizumab in patients with mutations associated with pooroutcome with available standard of care therapies, including STK11, KRAS, KEAP-1 andSMARCA4 mutations, may respond as if they have no mutations in these genes.

At the 2023 AACR meeting, BerGenBio, its investigators and itscollaborator Merck announcedfindings indicating benefit frombemcentinibin combination with pembrolizumab treatment in2L NSCLC patients harboring KEAP1 mutations, which can result in STK11 loss of function.Thesedata indicate that the relevant patient populations who may benefit from the addition ofbemcentinibto standard of care therapies may be broader than STK11m patients alone. Thiswill be further assessed in the on-going BGBC016 study in 1L STK11m NSCLC patients.

2L+ NSCLC Trial (BGBIL005)

In Q4 2022, we announced that in addition to the encouraging ORR and DCR data previouslypresented from the Investigator Led Study phase 1b/2a trial in whichbemcentinibwascombined with docetaxel, the final mPFS of 3.1 months and mOS of 12.3 months furthersupport the clinical benefit of combiningbemcentinibwith chemotherapy.

Oncology: Relapsed/Refractory AML/MDS

Following the end of the quarter, the Company held a business update conference call on May 15,2023, that included the topline results of the Phase 1b/2a BGBC003 multicenter open-label studyofbemcentinibas a single agent and in combination with low-dose cytarabine (LDAC) ordecitabine in patients with acute myeloid leukemia or as a single agent in patients withmyelodysplastic syndrome.

• Two cohorts of patients in BGBC003 were treated withbemcentinibas a single agent(monotherapy). In Cohort B1, in patients with Relapsed/Refractory (R/R) AML, (n=11),bemcentinib provided an ORR of 18.2% and a mOS of 18 months. In Cohort B4, in patientswith relapsed/high risk MDS, bemcentinib monotherapy provided an ORR of 18.8% with a mOSof 9.2months. The Company believes the mOS achieved is substantially longer than historicalcomparators in these same patient populations, providing evidence of single-agent efficacy ofbemcentinib.

• Furthermore,bemcentinibin combination with LDAC appeared to provide substantial mOSbenefit to patients with R/R AML (n=27) achieving an ORR of 18.5% and a mOS of 8months.Although these findings are encouraging, the Company has decided not to further pursueclinical trials in this indication given the change in standard of care therapies in these patientpopulations.

Oncology: Mesothelioma

The topline results of the investigator led BGBIL011/MiST3 mesothelioma trial were presentedpost-quarter on June 5, 2023, in an oral presentation at the 2023 American Society of ClinicalOncology (ASCO) meeting in an abstract titled:Bemcentiniband pembrolizumab in patients withrelapsed mesothelioma: MiST3, a phaseIIatrial with cellular and molecular correlates of efficacy.

MiST, the Mesothelioma Stratified Therapy umbrella trial, is a British Lung Foundation fundedstudy dedicated to improving survival outcomes for patients with mesothelioma.MiST3, the thirdarm of the trial, was designed to assess the efficacy of AXL/PD-1 inhibition with the combinationofbemcentiniband pembrolizumab.Key results include:

• 26 patients with relapsed mesothelioma were enrolled inMiST3and all received at least onedose ofbemcentiniband pembrolizumab.
• The primary endpoint of disease control rate at 12 weeks (DCR12w) was met: 46.2% (90% CI:29.2, 63.4).
• Secondary endpoints included a disease control rate at 24 weeks (DCR24w) of 38.5% (95% CI:20.2, 59.4) and an overall response rate of (ORR) of 15.4% (95% CI: 4.4, 34.9).
• The combination ofbemcentiniband pembrolizumab was generally safe and well-tolerated.

Severe Respiratory Infections (SRIs)

The Company believes thatbemcentinibblocks viral entry and replication, stimulates the innateimmune system, and promotes lung tissue repair positioning it well for the treatment of severerespiratory infections.

BerGenBioannounced after the quarter on April 25, 2023, that after assessing the significantdrop in hospitalizations attributed to COVID-19 during the 2022-23 winter season, the EU-SolidActTrial Steering Committee in accordance with the Company decided to pause the Phase2b trial evaluatingbemcentinibin hospitalized COVID-19 patients until a potential accelerationin hospitalizations warrant further evaluation ofbemcentinibin this population. Previously theCompany has completed two Phase 2 trials withbemcentinibin hospitalized COVID-19 patients,showing promising clinical activity.

Bemcentinibis currently being evaluated in preclinical studies for SRIs causing Acute RespiratoryDistress Syndrome (ARDS) and initial results are expected during 2023.
