Merck Drives New Innovation & Adds Capacity to Advance Next Generation Antibody-drug Conjugate (ADC) Therapies

Merck | October 29, 2021

Merck, a leading science and technology company, today announced that its Life Science business sector has launched new technology and expanded capacity to advance ADC therapies. These initiatives underscore Merck's continued investment in novel modalities and support the company's efforts to double its ADC and high-potent active pharmaceutical ingredient (HPAPI) capacity in the near future.

"ADCs have experienced remarkable growth, with commercially approved ADCs tripling in the past three yearsWe are a pioneer in this space, involved in 50 percent of the commercially approved ADCs on the market today. This latest innovation and additional capacity help bring novel treatments to cancer patients around the world and reinforce our commitment to shaping the future of these novel modalities.

Andrew Bulpin, head of Process Solutions, Life Science, at Merck

With the launch of its ChetoSensar™ technology, Merck is one of the front runners working to address the hydrophobicity of ADCs, in tandem with its CDMO services.  Many ADC candidates have poor aqueous solubility and Merck estimates that more than 20 percent of ADC clinical terminations are caused by this issue. The company's new ChetoSensar™ technology improves ADC solubility, therefore giving hope to ADCs that were previously terminated.

The payloads commonly used for ADCs are highly-complex molecules that take many steps to synthesize. Based on Merck's calculations, its new DOLCORE™ platform significantly reduces the development and manufacturing time required, increasing speed-to-market for a novel Dolostatin-based ADC payload by up to a year.

In addition, the company will enhance the ADC capabilities of its clinical manufacturing facility in St. Louis, Missouri, USA, in December. This facility will provide larger footprint to enable large-scale production including chromatographic purification for early phase clinical supply. This follows last year's announcement of a €59 million expansion of Merck's facility near Madison, Wisconsin, USA, which will double its HPAPI kilo lab capacity and enable the company to expedite the manufacture of HPAPIs, ADC linker/payloads, and complex APIs.

This innovation and additional capacity support the company's ambition to accelerate growth through investments in the "Big Three," including the Process Solutions business unit within the Life Science business sector as a key driver. 

With 15 years of experience developing and manufacturing ADCs, Merck offers unique CDMO services streamlined with a single, highly experienced provider. The company leverages its global network and deep expertise to tailor each molecule's unique journey, while creating the dynamic client partnerships drug manufacturers need to help reach their critical milestones. Merck integrates contract development and manufacturing with the industry's broadest product offering across multiple modalities. Customers can also seamlessly integrate BioReliance® services from the company's leading biosafety testing portfolio. 

Merck recently announced expansion projects in Darmstadt, Germany; Cork, Ireland; Buchs, Switzerland; Carlsbad, California, USA; Madison, Wisconsin, USA; Jaffrey, New Hampshire, USA; and Danvers, Massachusetts, USA. These expansions are part of an ambitious, multi-year program to increase the industrial capacity and capabilities of the Life Science business sector to support growing global demand for lifesaving medications and to make significant contributions to public health.

Avacta Completes Fourth Dose Escalation in AVA6000 Phase 1 Clinical Study

Avacta | January 23, 2023

Avacta Group plc, a leading life sciences company focused on developing innovative, targeted oncology medicines and powerful diagnostics, recently announced that AVA6000 has maintained a very favorable safety profile in the fourth dose cohort of the ALS-6000-101 dose escalation phase 1 clinical trial. Furthermore, analysis of tumor samples acquired from six patients across multiple cohorts shows that doxorubicin is being released within the tumor tissue, supporting the pre|CISIONTM technology's tumor-targeting capability. Patients in cohort 4 continue to tolerate AVA6000 well, with a significant decrease in the occurrence and severity of the commonly associated toxicities with the administration of traditional doxorubicin treatment. Nausea, vomiting, Alopecia, mucositis, myelosuppression, and cardiotoxicity are all among the typical toxicities. Notably, the typical drug-related cardiotoxicity of doxorubicin was not found even at the highest dosage levels in group 4, equivalent to more than double the standard dose of doxorubicin. In order to confirm the release of the active chemotherapy, doxorubicin, in tumor tissue, several tumor biopsies acquired from patients in different cohorts have been analyzed. This analysis demonstrates that AVA6000 targets the release of doxorubicin to tumor tissue at therapeutic levels that are significantly higher than those detected in the bloodstream at the same time point. To date, AVA6000 has been administered to 19 patients with advanced and/or metastatic solid tumors who were enrolled across four groups. Based on the very favorable safety profile of AVA6000 in the study thus far, the Safety Data Monitoring Committee (SDMC) has recommended that the study be extended to higher dose cohorts in order to identify a maximum tolerated dose (MTD) required to inform dosing levels for the phase 1b and future studies. The Company anticipates completing these additional cohorts within the first half of 2023. About Avacta Avacta is a healthcare group that promotes human health and well-being by creating new cancer treatments and powerful in vitro diagnostics. Its mission is to create the future of medicine by producing safe and effective medications as well as high-performance diagnostics using its unique Affimer® and pre|CISIONᵀᴹ platforms. By merging these two platforms, the Company is constructing a pipeline of innovative cancer therapeutics to fulfil its goal of developing successful treatments for all cancer patients, including those who do not react to current immunotherapies.

XtalPi Inc. | December 29, 2022

One of the pioneering pharmaceutical technology companies - XtalPi, powered by artificial intelligence (AI) and automation, has recently announced a strategic collaboration with Singapore's national platform for drug discovery and development, the Experimental Drug Development Centre (EDDC), which is hosted by the Agency for Science, Technology, and Research of Singapore (A*STAR). The goal of this partnership is to find novel treatment candidates for non-small cell lung cancer (NSCLC). “According to Research and Markets, the size of the global market for NSCLC treatments will surpass USD 20 billion by 2027” Lung cancer is the second-most prevalent cancer worldwide and the leading cause of cancer-related mortality. NSCLC accounts for more than 80% of all lung cancer occurrences, while its incidence continues to rise worldwide. Despite growing interest and investment in drug research, there is a substantial unmet demand for effective targeted therapeutic alternatives for NSCLC patients to improve outcomes. In this partnership, EDDC and XtalPi will work together to find promising candidates against an NSCLC target chosen by EDDC. XtalPi will use its AI technology, automation platform, and expert domain knowledge. It will also use quantum physics and an AI-driven platform to create and test millions of molecules for the De-novo drug design. Iterations will be used in its robotics-powered synthesis and testing lab to confirm and improve the predicted top-performing molecules with desirable drug properties. EDDC will give helpful information and data about the new NSCLC target, which will speed up the process of finding new drugs and carry the program forward. XtalPi said in a statement that it is delighted to work with EDDC. It intends to help people all over the world by using AI and automation to improve the speed, size, variety, and success rate of drug research and development. In line with this, EDDC stated that it is excited to collaborate with XtalPi to translate science and research into practical and targeted cancer therapies. Furthermore, EDDC is confident that this collaboration will accelerate the development of much-needed targeted therapies for NSCLC patients due to XtalPi's experience in AI and automation technologies.
