The Company announced positive initial data from the DisTinGuish study on Monday, September 13, 2021 based on 25 G/GEJ patients enrolled in the trial that showed DKN-01 in combination with tislelizumab and chemotherapy as first-line therapy was well tolerated with compelling activity. The results presented at the ESMO (Free ESMO Whitepaper) Congress today included additional patient data stratified by tumoral PD-L1 expression levels based on visually-estimated combined positive score (vCPS), showing that robust objective clinical responses can be achieved from this combination regimen independently of PD-L1 expression.

"Initial data from this trial have shown that patients with high levels of DKK1 expression, a group with a poor prognosis, had encouraging responses to treatment. The additional data presented today show evidence that not only is DKK1 a critical biomarker in predicting response to DKN-01 and tislelizumab therapy, but also that the combination can induce deep responses regardless of the patient’s PD-L1 status, including particularly poor prognosis patients with both low PD-L1 and high DKK1," said Samuel Klempner, MD, Member of the Faculty at Massachusetts General Hospital Cancer Center and Harvard Medical School. "Taken together, these are promising results for the combination therapy of DKN-01 with tislelizumab and chemotherapy in first line patients with gastric or gastroesophageal junction cancers."

About the DisTinGuish Study

The DisTinGuish study (NCT04363801) is a Phase 2a study of DKN-01 in combination with tislelizumab, an anti-PD-1 antibody, with or without chemotherapy as first-line or second-line therapy in patients with inoperable, locally advanced, G/GEJ adenocarcinoma. The study is being conducted in two parts in the United States and the Republic of Korea. Enrollment of Part A has been completed with 25 first-line HER2- G/GEJ cancer patients whose tumors express either high levels of DKK1 (DKK1-high) or low levels of DKK1 (DKK1-low). Part B of the study will enroll up to 48 patients with second-line, DKK1-high G/GEJ cancer. Leap is conducting this combination study as part of an exclusive option and license agreement with BeiGene for the development of DKN-01 in Asia (excluding Japan), Australia, and New Zealand.

Key Findings

Among patients who received a full cycle of DKN-01 therapy, the ORR was 68.2%, with 90% ORR in DKK1-high patients and 56% in DKK1-low patients
Response was independent of PD-L1 expression, and particularly strong in the less favorable to checkpoint inhibitor therapy, PD-L1 low (vCPS < 5), population
Among those patients with PD-L1-low expression (vCPS < 5), the ORR was 79%, with 100% in DKK1-high patients and 57% in DKK1-low patients
Among those patients with PD-L1-high expression (vCPS ≥ 5), the ORR was 67%, with 75% ORR in DKK1-high patients and 50% in DKK1-low patients
DKK1 levels could not be determined in one patient who had PD-L1 expression data; however, the patient’s PD-L1 expression level was determined to be low (vCPS score 0) and the patient achieved a partial response
DKK1 expression and PD-L1 expression are not correlated
Median duration of response and progression-free survival data are not yet mature, and patient follow-up continues
Twenty-five first-line patients were enrolled, and as of the cut-off date of the presentation, 15 patients had experienced a partial response (PR), six patients had a best response of stable disease (SD), one patient was non-evaluable for response (NE), and three patients were unable to complete a full cycle of DKN-01 therapy (non-modified ITT (mITT)).

Among the 21 patients that had RNAscope DKK1 expression available, 12 were DKK1-high [9 PR, 1 NE, 2 non-mITT] and 9 were DKK1-low [5 PR, 4 SD].

Among the 20 patients that had PD-L1 expression available, 14 were PD-L1 low vCPS < 5 [11 PR, 3 SD] and 6 were PD-L1 high vCPS > 5 [4 PR, 1 SD, 1 NE].

On September 15, 2021 Takeda Pharmaceutical Company Limited (TSE:4502/NYSE:TAK) ("Takeda") reported that the U.S. Food and Drug Administration (FDA) has approved EXKIVITY (mobocertinib) for the treatment of adult patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) exon 20 insertion mutations as detected by an FDA-approved test, whose disease has progressed on or after platinum-based chemotherapy (Press release, Takeda, SEP 15, 2021, View Source [SID1234587769]). EXKIVITY, which was granted priority review and received Breakthrough Therapy Designation, Fast Track Designation and Orphan Drug Designation from the FDA, is the first and only approved oral therapy specifically designed to target EGFR Exon20 insertion mutations. This indication is approved under Accelerated Approval based on overall response rate (ORR) and DoR. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.

"The approval of EXKIVITY introduces a new and effective treatment option for patients with EGFR Exon20 insertion+ NSCLC, fulfilling an urgent need for this difficult-to-treat cancer," said Teresa Bitetti, president, Global Oncology Business Unit, Takeda. "EXKIVITY is the first and only oral therapy specifically designed to target EGFR Exon20 insertions, and we are particularly encouraged by the duration of the responses observed with a median of approximately 1.5 years. This approval milestone reinforces our commitment to meeting the needs of underserved patient populations within the oncology community."

The FDA simultaneously approved Thermo Fisher Scientific’s Oncomine Dx Target Test as an NGS companion diagnostic for EXKIVITY to identify NSCLC patients with EGFR Exon20 insertions. NGS testing is critical for these patients, as it can enable more accurate diagnoses compared to polymerase chain reaction (PCR) testing, which detects less than 50% of EGFR Exon20 insertions.

"EGFR Exon20 insertion+ NSCLC is an underserved cancer that we have been unable to target effectively with traditional EGFR TKIs," said Pasi A. Jänne, MD, PhD, Dana Farber Cancer Institute. "The approval of EXKIVITY (mobocertinib) marks another important step forward that provides physicians and their patients with a new targeted oral therapy specifically designed for this patient population that has shown clinically meaningful and sustained responses."

"Patients with EGFR Exon20 insertion+ NSCLC have historically faced a unique set of challenges living with a very rare lung cancer that is not only underdiagnosed, but also lacking targeted treatment options that can improve response rates," said Marcia Horn, executive director, Exon 20 Group at ICAN, International Cancer Advocacy Network. "As a patient advocate working with EGFR Exon20 insertion+ NSCLC patients and their families every day for nearly five years, I am thrilled to witness continued progress in the fight against this devastating disease and am grateful for the patients, families, healthcare professionals and scientists across the globe who contributed to the approval of this promising targeted therapy."

The FDA approval is based on results from the platinum-pretreated population in the Phase 1/2 trial of EXKIVITY, which consisted of 114 patients with EGFR Exon20 insertion+ NSCLC who received prior platinum-based therapy and were treated at the 160 mg dose. Results were presented at the 2021 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting from the Phase 1/2 trial and demonstrated a confirmed ORR of 28% per independent review committee (IRC) (35% per investigator) as well as a median DoR of 17.5 months per IRC, a median overall survival (OS) of 24 months and a median progression-free survival (PFS) of 7.3 months per IRC.

The most common adverse reactions (>20%) were diarrhea, rash, nausea, stomatitis, vomiting, decreased appetite, paronychia, fatigue, dry skin, and musculoskeletal pain. The EXKIVITY Prescribing Information includes a boxed warning for QTc prolongation and Torsades de Pointes, and warnings and precautions for interstitial lung disease/pneumonitis, cardiac toxicity, and diarrhea.

The FDA review was conducted under Project Orbis, an initiative of the FDA Oncology Center of Excellence (OCE), which provides a framework for concurrent submission and review of oncology products among international partners. We look forward to continuing our work with regulatory agencies across the globe to bring mobocertinib to patients.

About EGFR Exon20 Insertion+ NSCLC
Non-small cell lung cancer (NSCLC) is the most common form of lung cancer, accounting for approximately 85% of the estimated 2.2 million new cases of lung cancer diagnosed each year worldwide, according to the World Health Organization.1,2 Patients with epidermal growth factor receptor (EGFR) Exon20 insertion+ NSCLC make up approximately 1-2% of patients with NSCLC, and the disease is more common in Asian populations compared to Western populations.3-7 This disease carries a worse prognosis than other EGFR mutations, as EGFR TKIs – which do not specifically target EGFR Exon20 insertions – and chemotherapy provide limited benefit for these patients.

Takeda is committed to continuing research and development to meet the needs of the lung cancer community through the discovery and delivery of transformative medicines.

EXKIVITY IMPORTANT SAFETY INFORMATION
QTc Interval Prolongation and Torsades de Pointes: EXKIVITY can cause life-threatening heart rate-corrected QT (QTc) prolongation, including Torsades de Pointes, which can be fatal, and requires monitoring of QTc and electrolytes at baseline and periodically during treatment. Increase monitoring frequency in patients with risk factors for QTc prolongation. Avoid use of concomitant drugs which are known to prolong the QTc interval and use of strong or moderate CYP3A inhibitors with EXKIVITY, which may further prolong the QTc. Withhold, reduce the dose, or permanently discontinue EXKIVITY based on the severity of QTc prolongation.

Interstitial Lung Disease (ILD)/Pneumonitis: Monitor patients for new or worsening pulmonary symptoms indicative of ILD/pneumonitis. Immediately withhold EXKIVITY in patients with suspected ILD/pneumonitis and permanently discontinue EXKIVITY if ILD/pneumonitis is confirmed.
Cardiac Toxicity: Monitor cardiac function, including left ventricular ejection fraction, at baseline and during treatment. Withhold, resume at reduced dose or permanently discontinue based on severity.
Diarrhea: Diarrhea may lead to dehydration or electrolyte imbalance, with or without renal impairment. Monitor electrolytes and advise patients to start an antidiarrheal agent at first episode of diarrhea and to increase fluid and electrolyte intake. Withhold, reduce the dose, or permanently discontinue EXKIVITY based on the severity.
Embryo-Fetal Toxicity: Can cause fetal harm. Advise females of reproductive potential of the potential risk to a fetus and to use effective non-hormonal contraception.

On September 15, 2021 PsiOxus Therapeutics, Ltd. (PsiOxus), a tumor re-engineering company, reported that they will present key safety and translational data from their first-in-human phase 1 FORTITUDE clinical study at the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress 2021 this week (Press release, PsiOxus Therapeutics, SEP 15, 2021, View Source [SID1234587766]). Data from the completed monotherapy dose-escalation part of the FORTITUDE study, initiated in 2019 to assess the safety and tolerability of the NG-350A T-SIGn vector, will be presented on Friday 16th September 2021, with the poster available in full at www.psioxus.com shortly afterwards.

NG-350A is a T-SIGn vector designed to re-engineer cancers by selectively expressing a CD40 agonist monoclonal antibody, a potent activator of immuno-inflammatory responses, within the tumour microenvironment. PsiOxus is developing this agent as one of several products within its T-SIGn portfolio of vectors that combine systemic delivery with localized production of powerful transgene payloads to allow the selective re-engineering of both primary and metastatic tumors.

The data to be presented at the ESMO (Free ESMO Whitepaper) Congress show that IV delivery of NG-350A results in sustained elevations of inflammatory cytokines in the phase 1 FORTITUDE trial. In particular, marked and persistent dose-dependent increases in both IL-12 and IFNγ were observed after a single 1-week course of NG-350A, indicative of robust activation of antigen presenting cells via CD40 agonism generated within the tumor. Expansion of new T cell clones, a high proportion of which were new clones, was also observed following a single cycle of NG-350A. Safety data from the 25 patients treated with NG-350A as part of the now completed monotherapy dose-escalation part of FORTITUDE demonstrated that NG‑350A was well-tolerated, with few of the adverse events associated with systemic delivery of anti-CD40 agonists observed.

Together, these data suggest NG-350A contributes to the re-programming of the tumour microenvironment while avoiding the toxicity associated with systemic non-localized dosing of anti-CD40 antibodies.

"The headline data shared at the ESMO (Free ESMO Whitepaper) Congress confirms previous findings that our T-SIGn vector replicates selectively in primary tumor cells and metastases and persists for several months after intravenous delivery. Even more importantly, the biomarker data indicates that ongoing vector replication in tumors effectively translates into sustained production of the transgene payload, in this case a CD40 agonistic antibody. This translational data is a first in class demonstration of a downstream effect of tumor re-engineering, using T-SIGn vectors to turn the patient’s tumor cells into small drug factories," said Tom Lille, M.D., Ph.D., Chief Medical Officer, PsiOxus.

Based on these highly promising data, NG-350A will be assessed in combination with an anti–PD-1 checkpoint inhibitor in Part B of FORTITUDE.
