2 It is this complexity that necessitates powerful, targeted combination therapies. To bring us closer to curing cancer, a combination of effective drugs with non-overlapping mechanisms of action is required. To bring us closer to curing cancer, a combination of effective drugs with non-overlapping mechanisms of action is required.
For example, PROTACs targeting STAT3, a protein crucial for tumor growth, have shown promise where conventional therapies have failed. Similarly, PROTACs can target and degrade overexpressed proteins, offering a way to overcome drug resistance, a common issue in cancer treatment.
Its structure makes it incredibly difficult for drugs to bind effectively, which has stymied drugdevelopment for decades. The binding pockets on KRAS are shallow and polar , not ideal for the kinds of interactions needed for strong, effective drug binding.
Throughout the course of our lives, natural and environmental factors can break DNA. Breaks in both DNA strands are a particularly dangerous threat to genome stability. At a DNA double-strand break (DSB), potentially lost sequence information cannot be recovered from the same DNA molecule.
Historically, these indications have challenged the one-size-fits-all treatment approach due to patient variability, such as genetic differences in drug metabolism and underlying health conditions. Hematological cancer cells can also develop resistance to therapies over time, reducing treatment effectiveness.
Today these medicines, called targeted therapies, are available for treating many forms of cancer. Targeted therapies took center stage when Alice Shaw started her career as a physician-scientist caring for patients with lung cancer. Clinical trial investigators are the eyes and ears in the clinic for pharmaceutical drugdevelopers.
Antibody-Drug Conjugates: Advancing Precision Therapy ADCs represent a compelling combination of targeted antibody therapy and potent chemotherapy, aiming to enhance treatment efficacy while minimizing systemic toxicity.

We have the ability to generate precise antibodies to a diverse range of targets, which together with Boehringer Ingelheim’s strength in drugdevelopment capabilities, could mean multiple new, more personalized treatments in the future for patients,” said Emily M. Leproust, Ph.D., CEO and co-founder of Twist. About Twist Biopharma.
Understanding blood-brain barrier function has been at the heart of research into drugtherapies for neurological diseases. That’s why we are excited about the discovery of this variant in fibronectin, which may be a good target for drugdevelopment,” said study co-leader Richard Mayeux.
They are specifically formulated to emit radiation that can be detected by imaging equipment or deliver targeted radiation therapy to specific tissues or organs within the body, serving as a diagnostic and therapeutic tool for various medical conditions.
It has become a fundamental tool for researchers to explore the complexities of genetic information and conduct genetic-informed drugdevelopment. Sponsors have used NGS to screen patients for clinical trial eligibility and patient stratification , expanded CDx development, and comprehensive genomic profiling (CGP).
What specific cost-cutting measures can AI provide in the manufacturing process of cell and gene therapy, and how do these compare to traditional methods? The cell and gene therapy (CGT) space provides a great example of the potential of AI. AI can vastly improve cell culture, a critical step in cell therapy production.
The current landscape of protein drugdevelopment is characterised by accelerated timelines where new drugs are approved in months rather than years. Hence, in many cases an earlier IND may be prevented by the timely provision of representative Drug Substance (DS) to execute such toxicology studies.

The general notion is that patients should be viewed individually, rather than strictly as members of some larger general population, and that their specific genetic background, environment, and lifestyle choices should be considered throughout drugdevelopment to the point of treatment and continuing patient care.
Patients frequently receive up to four therapies at once and go through multiple prolonged courses of treatment to keep recurrence and progression at bay. Commonly combined treatment options include antineoplastics (chemotherapies), radiation therapy, corticosteroids, immunomodulators, proteasome inhibitors, and monoclonal antibodies.
Genetic testing may help confirm a clinical diagnosis, help predict disease prognosis and progression, facilitate early detection of symptoms, allow for family planning and genetic counseling, inform optimal treatments and therapies, and/or promote enrollment in clinical trials.
Draft guidance on potency assays for CGT products garners extensive stakeholder input Late last year, the FDA published a draft update to its 2011 guidance on potency assays for cell and gene therapy products, unveiling a major shift in approach to the issue. How does “potency” apply to cell and gene therapy (CGT) products?
Tom Ireland writes about the companies and technologies that are reimagining phage therapy. Soon after its publication, scientists, journalists, and investors were revisiting ‘phage therapy’ as a promising alternative to our failing antibiotics. Nearly three million drug-resistant infections occur annually in the U.S.
Unlike almost every other cell type (except B cells), T cells do not have the exact same chromosomal DNA sequences as other cells in the body. In previous decades, isolation, sequencing and characterisation of DNA encoding a specific TCR was laborious and technically challenging. Engineering soluble T-cell receptors for therapy.
But immunotherapy was not yet widely used and had not been applied clinically to Merkel cell carcinoma, so she received traditional chemotherapy and radiation therapy, suffering life-threatening complications along the way. His mother had a presentation of the disease that suggested her immune system was already on the job.
