Leap Therapeutics, Inc. | February 01, 2022
Leica Biosystems, a cancer diagnostics company, has entered into an agreement with Leap Therapeutics, a biotechnology company, to develop a companion diagnostic to detect Dickkopf-related protein 1. The assay will be used to support clinical development of Leap Therapeutics' anti-DKK1 cancer therapy, DKN-01, currently being studied in clinical trials.
DKK1 is a protein often implicated in cancer, enabling tumor cells to suppress the immune system and lead to unregulated growth. Overexpression of DKK1 is associated with poor survival in cancer patients.
Leap Therapeutics is currently advancing the development of DKN-01, a humanized monoclonal antibody that targets DKK1, to treat cancer. The company is currently studying the drug as part of a combination therapy regimen in a Phase 2 clinical trial in patients with gastric or gastroesophageal junction cancer.
The assay developed by Leica Biosystems will utilize RNAscope™ technology from Bio-Techne on the BOND-III Automated Staining System, which allows for detection of DKK1 with high sensitivity and specificity, to help identify patients most likely to benefit from DKN-01 treatment.
"Companion Diagnostics are a step toward treating cancer patients based on the biomarker makeup of their disease.We are excited to partner with Leap to advance cancer care."
Rachel Skelton, Senior Director of Pharma Partnerships at Leica Biosystems
Companion Diagnostics are tests that may be used to determine if a patient's tumor has the biomarker that will predict the outcome of a treatment with a specific therapy.

Daiichi Sankyo | December 24, 2021
Daiichi Sankyo Company, Limited announced that the U.S. Food and Drug Administration has granted Breakthrough Therapy Designation to patritumab deruxtecan, a potential first-in-class HER3 directed antibody drug conjugate, for the treatment of patients with metastatic or locally advanced EGFR-mutated non-small cell lung cancer with disease progression on or after treatment with a third-generation tyrosine kinase inhibitor and platinum-based therapies.
Lung cancer is the second most common cancer and the leading cause of cancer-related mortality worldwide, with 80% to 85% classified as NSCLC.1,2,3 While the efficacy of targeted therapy with EGFR TKIs is well-established in the treatment of advanced EGFR-mutated NSCLC, which comprises approximately 30% of patients, the development of a broad range of resistance mechanisms commonly leads to disease progression.4,5,6 After failure of an EGFR TKI, platinum-based chemotherapy has limited efficacy with progression-free survival (PFS) of approximately 4.4 to 6.4 months.7 Subsequent salvage therapies after EGFR TKI and platinum-based chemotherapy have PFS of 2.8 to 3.2 months.8
The U.S. FDA’s BTD is designed to accelerate the development and regulatory review of potential new medicines that are intended to treat a serious condition and address a significant unmet medical need. The new medicine needs to have shown encouraging preliminary clinical results that demonstrate substantial improvement on a clinically significant endpoint over available medicines.
The FDA granted the BTD based on data from the dose escalation portion and two expansion cohorts of a three-cohort phase 1 study of patritumab deruxtecan. Extended follow-up data from the dose escalation portion and dose expansion cohort 1 of the study were recently presented at the 2021 American Society of Clinical Oncology annual meeting and published in Cancer Discovery. This is the first BTD for patritumab deruxtecan and the seventh BTD across Daiichi Sankyo’s oncology portfolio.
“The Breakthrough Therapy Designation for patritumab deruxtecan acknowledges the need for new treatment approaches to overcome resistance and improve survival in patients with metastatic TKI-resistant, EGFR-mutated non-small cell lung cancer. We are proud that the FDA has once again recognized our innovative science and technology and we look forward to bringing this potential first-in-class HER3 directed antibody drug conjugate to patients with this specific type of lung cancer as quickly as possible.”

About Non-Small Cell Lung Cancer
Lung cancer is the second most common cancer and the leading cause of cancer-related mortality worldwide, with 80% to 85% classified as NSCLC.1,2,3 There were an estimated 2.2 million new cases of lung cancer and 1.8 million deaths in 2020.9 NSCLC is diagnosed at an advanced stage in more than 50% of patients and often has a poor prognosis with worsening outcomes after each line of subsequent therapy.10,11,12
The introduction of targeted therapies and checkpoint inhibitors in the past decade has improved the treatment landscape for patients with advanced or metastatic NSCLC. For patients with advanced EGFR-mutated NSCLC, targeted therapy with EGFR TKIs offer higher response rates and PFS compared to chemotherapy.13 However, most patients eventually develop resistance to these therapies and subsequent therapy after EGFR TKI with platinum-based chemotherapy have limited efficacy with PFS of approximately 4.4 to 6.4 months.7,14 Subsequent salvage therapies after EGFR TKI and platinum-based chemotherapy have PFS of 2.8 to 3.2 months.8 New treatment approaches are needed to overcome resistance and improve survival in this subtype of NSCLC.
HER3 is a member of the EGFR family of receptor tyrosine kinases, which are associated with aberrant cell proliferation and survival.15 Approximately 25% to 30% of lung cancers have an EGFR-activating mutation, and it is estimated that about 83% of all NSCLC tumors express the HER3 protein, which can be associated with an increased incidence of metastases, reduced survival and resistance to standard of care treatment.16,17,18 Currently, no HER3 directed medicines are approved for the treatment of cancer.
About the Phase 1 Non-Small Cell Lung Cancer Study
The global, multicenter, open label, two-part phase 1 study is evaluating patritumab deruxtecan in previously treated patients with metastatic or unresectable NSCLC.
The dose escalation part of the study evaluated patients with EGFR-mutated disease either with progression on osimertinib or T790M-negative after progression on erlotinib, gefitinib or afatinib. The primary objective of this part of the study was to assess the safety and tolerability of patritumab deruxtecan and determine the recommended dose for expansion.
The dose expansion part of the study is evaluating patritumab deruxtecan at the RD in three cohorts. Cohort 1 includes patients with locally advanced or metastatic EGFR-mutated NSCLC who experienced disease progression after taking one or more EGFR TKIs and one or more platinum-based chemotherapy regimens. Cohort 2 includes patients with squamous or non-squamous NSCLC without EGFR-activating mutations following platinum-based chemotherapy and following an anti-PD-1 or anti-PD-L1 antibody regimen. Cohort 3 includes patients with NSCLC with EGFR-activating mutations including any histology other than combined small cell and non-small cell lung cancer; patients in Cohort 3 are randomized 1:1 to receive the 5.6 mg/kg RDE regimen or an escalating up-titration regimen of patritumab deruxtecan.
The primary objective of the dose expansion part of the study is to assess efficacy of patritumab deruxtecan as measured by confirmed objective response rate assessed by blinded independent central review. Secondary study endpoints include investigator-assessed ORR, safety and pharmacokinetics. The study enrolled patients at multiple sites in Asia, Europe and North America.
