"Approval of our first CTA represents an important validation of our approach and a significant milestone for Achilles," said Dr Iraj Ali, CEO of Achilles Therapeutics. "Achilles was founded by world-leading experts in cancer evolution, bioinformatics and the delivery of cell-based immunotherapies and we are bringing together these disciplines to develop next-generation, patient-specific T cell therapies that harness the immune system to destroy cancer cells."

"The Achilles approach is a technological step forward in the immune-oncology space with the potential to bring the next wave of revolutionary new immunotherapies to cancer patients," said Dr Martin Forster, Chief Investigator for the study at University College London Hospitals (UCLH), the lead clinical site. "We are excited to be part of the study and look forward to enrolling patients into the clinical trial."

Achilles is developing personalised T cell therapies for solid tumours targeting clonal neoantigens: protein markers unique to each patient that are present on the surface of a cancer cell. Using its PELEUS bioinformatics platform, Achilles can identify clonal neoantigens from each patient’s unique tumour profile which are present on every cancer cell and can be recognised by the immune system. Achilles uses its proprietary process to manufacture clonal neoantigen T cells (cNeT) which exquisitely target the specific set of clonal neoantigens in each patient. The starting material for cNeT are tumour infiltrating lymphocytes (TILs) which are isolated from the patient’s own tumour sample. These T cells are already programmed to invade and attack the tumour, and previous clinical studies have shown that expanded TILs can debulk solid tumours with durable and potent responses. Targeting multiple clonal neoantigens that are present on all cancer cells, but not on healthy cells, reduces the risk that new mutations can induce immune evasion and therapeutic resistance, and allows individualised treatments to target and destroy tumours without harming healthy tissue.

A second clinical study in patients with metastatic or recurrent melanoma is anticipated to open later in 2019.

ISA Pharmaceuticals Announces Start of Phase 2 Combination Trial of ISA101b and Regeneron’s Cemiplimab in Oropharyngeal Cancer

On January 21, 2019 ISA Pharmaceuticals B.V., a clinical-stage company dedicated to the development of rationally designed immunotherapeutics, reported randomization of the first patient in a Phase 2 combination trial of its lead compound ISA101b and Regeneron´s (NASDAQ: REGN) anti-PD-1 antibody cemiplimab (REGN2810) (Press release, ISA Pharmaceuticals, JAN 21, 2019, View Source [SID1234532797]).

This double blind, placebo-controlled, randomized, phase 2 study (NCT03669718) will enroll approximately 164 patients with HPV16-positive oropharyngeal cancer (OPC), who have failed first-line chemotherapy. Patients will be randomly allocated on a 1:1 basis to the combination of cemiplimab/ISA101b or cemiplimab/placebo. In both study arms, patients will receive treatment in cycles of 3 weeks for up to 24 months. The primary efficacy objective of this trial is to assess whether the addition of ISA101b to cemiplimab will elicit a higher Overall Response Rate (ORR, as per RECIST 1.1 criteria) compared to cemiplimab plus placebo. Secondary endpoints include Progression Free Survival (PFS), Overall Survival (OS), as well as safety and tolerability of cemiplimab plus ISA101b (as compared to cemiplimab plus placebo). The study will be conducted at approximately 50 investigative sites in the USA and Europe.

ISA Pharmaceuticals´ lead compound ISA101 is a clinical-stage SLP immunotherapy targeting HPV16-induced diseases such as cervical cancer and head–and-neck cancer. It induces specific immune responses to the oncogenic E6 and E7 antigens of HPV16. Cemiplimab, also known as REGN2810, is currently under review by EMA and was approved by the U.S. Food and Drug Administration in September 2018 under the brand name Libtayo as monotherapy for patients with advanced cutaneous squamous cell carcinoma. Regeneron, in collaboration with Sanofi, is developing cemiplimab both alone and in combination with other therapies for the treatment of various cancers.

"We are excited about this new clinical trial with ISA101b and cemiplimab," said Dr. Leon Hooftman, CMO of ISA Pharmaceuticals. "ISA101b has already demonstrated very promising results when combined with nivolumab in a previous study in advanced HPV16-positive cancers. Particularly in patients with relapsed head-and-neck cancer the percentage of patients with a meaningful tumor response appeared to be twice as high as achieved with nivolumab alone. The objective of the current randomized trial is to confirm such clinical benefit of ISA101b in a controlled setting."

"In our collaboration with Regeneron that was announced in December 2017, this is the first of two indications in which we jointly aim to develop novel combination immunotherapies for cervical cancer and head-and-neck cancer," said Gerben Moolhuizen, CEO of ISA Pharmaceuticals. "I am very proud of the efforts of the joint team that allowed us to advance quickly to this stage. We look forward to the first read-out from the trial, which is expected in the second half of 2020."

Oropharyngeal cancer, a subtype of head-and-neck cancer, affects tissues of the throat (oropharynx), e.g. the base of the tongue, the tonsils, the soft palate, and the walls of the pharynx. Oropharyngeal cancers can be divided into two types: HPV-positive, which are related to human papillomavirus infection, and HPV-negative cancers, which are usually linked to alcohol or tobacco use.

BerGenBio announces start of phase I trial evaluating ADCT-601, a novel anti-AXL ADC, in patients with advanced solid tumours

On January 21, 2019 BerGenBio ASA (OSE:BGBIO), reported that the first patient has been dosed in a phase I clinical trial evaluating the safety, tolerability, pharmacokinetics and anti-tumour efficacy of ADCT-601, an AXL-targeting antibody drug conjugate (ADC), in patients with advanced solid tumours (Press release, BerGenBio, JAN 21, 2019, View Source [SID1234532796]).

ADCT-601 is composed of a humanised monoclonal antibody against human AXL (BGB601) discovered by BerGenBio, conjugated to a pyrrolobenzodiazepine (PBD) dimer toxin. BGB601 was out-licensed for ADC development to ADC Therapeutics SA (ADCT). In preclinical studies, ADCT-601 has demonstrated potent and specific anti-tumour activity in multiple in vivo models and was stable and well tolerated, as reported by ADCT at the American Association of Cancer Research (AACR) (Free AACR Whitepaper) annual congress in 2018.

The open-label, multi-centre, single arm phase I trial will enrol approximately 75 patients with selected tumour types and will be managed and sponsored by license partner ADC Therapeutics. For more information see View Source (accessing trial identifier NCT03700294).

Richard Godfrey, Chief Executive Officer of BerGenBio, commented: "We congratulate ADC Therapeutics on reaching this important milestone. We are pleased to now see three of our AXL-targeting modalities in clinical development with the potential to address large patient populations. Our focus remains on completing our ongoing oncology phase II programme with bemcentinib, a first-in-class highly selective oral AXL inhibitor, and start randomised, potentially pivotal trials later this year. In the meantime, we look forward to providing updates on the development of BGB149, a therapeutic AXL antibody, and ADCT-601, an anti-AXL ADC, as they progress through phase I testing."

About ADCT-601
BerGenBio out-licensed two novel and proprietary anti-AXL monoclonal antibodies invented by the Company to ADC Therapeutics SA (ADCT) for the development of an antibody drug conjugate (ADC).

ADCT-601 is composed of BGB601, a humanised monoclonal antibody that binds to human AXL, conjugated using GlycoConnect technology to a linker with a pyrrolobenzodiazepine (PBD) dimer toxin. Once bound to an AXL-expressing cell, ADCT-601 is internalised into the cell where enzymes release the PBD-based warhead. The PBD-based warhead has the ability to form highly cytotoxic DNA interstrand cross-links, blocking cell division and ultimately killing the cancer cell. ADCT-601 is currently undergoing Phase I clinical testing (NCT03700294).

Under the license, a series of development, regulatory and sales-based milestones are due to BerGenBio from ADCT upon the achievement of certain specified events. The first milestone payment is triggered during the phase I clinical study.

About AXL
AXL kinase is a cell membrane receptor and an essential mediator of the biological mechanisms underlying life-threatening diseases. In cancer, AXL suppresses the body’s immune response to tumours and drives cancer treatment failure across many indications. AXL inhibitors, therefore, have potential high value at the centre 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.

US FDA Approves ONTRUZANT® (trastuzumab-dttb), Samsung Bioepis’ First Oncology Medicine in the United States
