Application of a Novel 'Make and Test in Parallel' Strategy to Investigate the Effect of Formulation on the Pharmacokinetics of GDC-0810 in Healthy Subjects

Immunotherapy and drug sensitivity predictive roles of a novel prognostic model in hepatocellular carcinoma

Hepatocellular carcinoma (HCC) is one of the most significant causes of cancer-related deaths in the worldwide. Currently, predicting the survival of patients with HCC and developing treatment drugs still remain a significant challenge. In this study, we employed prognosis-related genes to develop and externally validate a predictive risk model. Furthermore, the correlation between signaling pathways, immune cell infiltration, immunotherapy response, drug sensitivity, and risk score was investigated using different algorithm platforms in HCC. Our results showed that 11 differentially expressed genes including UBE2C, PTTG1, TOP2A, SPP1, FCN3, SLC22A1, ADH4, CYP2C8, SLC10A1, F9, and FBP1 were identified as being related to prognosis, which were integrated to construct a prediction model. Our model could accurately predict patients' overall survival using both internal and external datasets. Moreover, a strong correlation was revealed between the signaling pathway, immune cell infiltration, immunotherapy response, and risk score. Importantly, a novel potential drug candidate for HCC treatment was discovered based on the risk score and also validated through ex vivo experiments. Our finds offer a novel perspective on prognosis prediction and drug exploration for cancer patients.

Small is Powerful: Demonstration of the Impact of Nanoformed Piroxicam in a Controlled Clinical Study

PURPOSE

New solutions are needed to enable the efficient use of poorly water-soluble drugs. Therefore, we aimed to demonstrate that decreasing particle size with a solution-to-particle method known as nanoforming can improve dissolution and thus bioavailability.

METHODS

Piroxicam, a poorly water-soluble non-steroidal anti-inflammatory drug (NSAID), was used as a model compound. A Quality-by-Design (QbD) approach was used to nanoform piroxicam and a design space was established. The pharmacokinetics of piroxicam nanoparticles were compared to two marketed products in a clinical trial.

RESULTS

Nanoformed tablets showed a 33% increase in exposure during the first hour after dosing (AUC0-1 h) compared with an immediate release tablet and was similar to a fast absorbing tablet incorporating complexation of piroxicam with β-cyclodextrin.

CONCLUSIONS

The results show that nanoforming enabled more rapid absorption in comparison to a typical marketed tablet and indicate that nanoforming is an alternative to complex formulation such as cyclodextrins based products. The study outcomes support the potential of nanoforming for producing fast-acting dosage forms of poorly soluble drugs.

Latest generation estrogen receptor degraders for the treatment of hormone receptor-positive breast cancer

INTRODUCTION

The selective estrogen receptor degrader (SERD) and full receptor antagonist provides an important therapeutic option for hormone receptor (HR)-positive breast cancer. Endocrine therapies include tamoxifen, a selective estrogen receptor modulator (SERM), that exhibits receptor agonist and antagonist activity, and aromatase inhibitors that block estrogen biosynthesis but which demonstrate acquired resistance. Fulvestrant, the only currently approved SERD, is limited by poor drug-like properties. A key focus for improving disease management has been development of oral SERDs with optimized target occupancy and potency and superior clinical efficacy.

AREAS COVERED

Using PubMed, clinicaltrials.gov, and congress websites, this review explored the preclinical development and clinical pharmacokinetics from early phase clinical studies (2015 or later) of novel oral SERDs, including giredestrant, amcenestrant, camizestrant, elacestrant, and rintodestrant.

EXPERT OPINION

Numerous oral SERDs are in clinical development, aiming to form the core endocrine therapy for HR-positive breast cancer. Through property- and structure-based drug design of estrogen receptor-binding, antagonism, degradation, anti-proliferation, and pharmacokinetic properties, these SERDs have distinct profiles which impact clinical dosing, efficacy, and safety. Assuming preliminary safety and activity data are confirmed in phase 3 trials, these promising agents could further improve the management, outcomes, and quality of life in HR-positive breast cancer.

Modulating target engagement of small molecules via drug delivery: approaches and applications in drug discovery and development

Drug-delivery technologies for modified drug release have been in existence for decades, but their utilization has been largely limited to post-launch efforts improving therapeutic outcomes. Recently, they have gained renewed importance because the pharmaceutical industry is steadily shifting to a more integrated discovery-development approach. In discovery, modulating target engagement via drug-delivery technologies can enable crucial pharmacological studies for building well-defined criteria for molecular design. In development, earlier implementation of delivery technologies can enhance the value of drug products through reduced dosing frequency and improved tolerability and/or safety profile, thereby leading to better adherence and therapeutic effectiveness.

The Financial Benefits of Faster Development Times: Integrated Formulation Development, Real-Time Manufacturing, and Clinical Testing

PURPOSE

Faster drug development times get new therapies to patients sooner and financially benefit drug developers by shortening the time between investment and returns and increasing the time on the market with intellectual property protection. The result is enhanced incentives to innovate. We provide a real-world example of the financial gains from quicker development using recent estimates of drug development costs, returns, and estimates of time reductions from an alternative early-stage drug development paradigm.

METHODS

We utilized data obtained from a drug development and manufacturing services organization to estimate the reduction in development time for drug sponsors from using an integrated platform of formulation development, real-time manufacturing, and clinical testing for 19 completed drug product development projects covering three key drug development activities (transitioning from first-in-human to proof-of-concept [FIH-PoC], modified release formulation development [MR], and enhanced solubility formulation development [ES]). A traditional drug development paradigm was taken as the base case and financial impacts of the alternative development program were determined relative to the base case.

FINDINGS

The total after-tax financial benefits of shorter development times from integrating formulation development, real-time manufacturing, and clinical testing when applied across a broad portfolio of investigational drugs ranged from $230.5 million to $290.1 million, $196.4 million to $247.5 million, and $102.6 million to $275.5 million, per approved new drug for FIH-PoC, MR, and ES applications, respectively (2018 dollars).

IMPLICATIONS

For the data we examined, this integrated development model yielded substantial financial benefits over traditional drug development.
