Zeneth is our expert, knowledge ‑based in silico software for predicting forced degradation pathways of organic active pharmaceutical ingredients (APIs). It provides valuable mechanistic understanding of how an API may degrade under stress conditions such as temperature, pH, water, oxygen, peroxide, light, metal ions, or radical initiators. Excipients and their impurities can also be explored […]

Lhasa Limited has been an advocate of data sharing for many years. In this piece, we explore the top 5 benefits of data sharing within Vitic. The benefits of data sharing include cost savings, the ability to make more informed decisions and the opportunity to define best practice through collaboration within the industry. Vitic is central to

In a world where we are all striving for progress, technology is also advancing quickly. Like many organisations across the life sciences industry – evidenced by > 80 Amazon Web Service (AWS) life sciences case studies –  Lhasa has adopted cloud, Software as a Service (SaaS), options across three notable areas: Mirabilis – reducing analytical testing by

Are you interested in collaboratively using data to predict and avoid adverse drug reactions? The Effiris consortium – currently composed of Takeda, GSK and UCB – is working to achieve just that. The project aims to help pharmaceutical organisations accelerate drug discovery through machine learning. Many readers will be very familiar with the fact that one

Lhasa Limited, in collaboration with Leadscope, Inc., are leading a working group of pharmaceutical toxicologists and consultants investigating the carcinogenic potency and structure-activity relationships of N-nitrosamines. This is in response to the recent discovery of N-nitrosamines in marketed pharmaceuticals and the regulatory changes that have resulted. The working group is coordinated on an informal basis

Introduction to Lhasa Carcinogenicity Database For many years the Carcinogenic Potency Database (CPDB)1, created by Lois Gold and her team, was an important source of long-term carcinogenicity study data. However, as the database had stopped being updated from 2007, Lhasa moved to safeguard the data by providing ongoing access through a freely available interface; the Lhasa

The introduction of purge arguments by Teasdale et al. has had a huge impact on the way in which companies consider the quality of their drug substances with respect to potentially mutagenic impurities (PMIs), allowing chemists to utilise their inherent knowledge of the physicochemical properties of the impurities within the synthetic process.1 This encourages a

The saying goes, “It takes a village to raise a child”. This sentiment can be translated to the work we do at Lhasa Limited, particularly to the work which we put into building Adverse Outcome Pathways (AOPs). To echo the sentiment in Chris Barber’s previous blog post, The challenge of building QSAR models; it is

Creating great software is a balance between multiple perspectives where favouring one perspective may be detrimental to another perspective. To add further complexity, these perspectives will vary depending on the project, the organisation, the team, or even the day. That said, there are a number of attributes to writing great software that are common to

The recent discovery of N-nitrosamine (nitrosamine) impurities in several marketed pharmaceuticals has led to a requirement for further investigation into nitrosamine mutagenic and carcinogenic activity. Updated regulatory requirements mean that marketing authorisation holders for human medicines, containing chemically synthesised active substances, must review their medicines for the possible presence of nitrosamines and test all products at
