Combination Therapies and Personalized Medicine

4.9K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Mechanistic Models: Compartment Models in Algorithms for Numerical Problem Solving

54
Mechanistic models play a crucial role in algorithms for numerical problem-solving, particularly in nonlinear mixed effects modeling (NMEM). These models aim to minimize specific objective functions by evaluating various parameter estimates, leading to the development of systematic algorithms. In some cases, linearization techniques approximate the model using linear equations.
In individual population analyses, different algorithms are employed, such as Cauchy's method, which uses a...

Targeted Cancer Therapies

7.6K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Area of Science:

  • Biotechnology
  • Process Engineering
  • Cell Therapy Manufacturing

Background:

  • Optimizing complex bioprocesses, especially in cell therapy, is challenging due to limited biological understanding and resource-intensive experimentation.
  • Developing customized, closed, and automated processes is vital for industrial translation and cost-effective patient treatment.
  • Bayesian optimization (BO) is an experimental design method, but its application in noisy, parallel bioprocess optimization requires further investigation.

Purpose of the Study:

  • To evaluate the performance of noisy, parallel Bayesian optimization (BO) for bioprocess optimization.
  • To assess the impact of increasing noise levels and parallel batch sizes on BO's effectiveness.
  • To compare the proposed BO method against the current industry state-of-the-art.

Main Methods:

  • In silico evaluation of noisy, parallel BO on two bioprocess models.
  • Testing with varying noise levels and parallel batch sizes.
  • Application to an in vitro monocyte purification unit operation.

Main Results:

  • Noisy, parallel BO significantly outperformed the industry state-of-the-art in silico.
  • The method required approximately 50% fewer experiments on average compared to existing approaches.
  • Successful application to an in vitro monocyte purification process demonstrated practical utility.

Conclusions:

  • Noisy, parallel Bayesian optimization is a powerful tool for optimizing complex bioprocesses.
  • This approach offers substantial efficiency gains in cell therapy process development.
  • The findings support the adoption of advanced BO techniques for industrial bioprocessing.
