Abstract:
Findings of a phase I/II trial of the adenosine 2A receptor blocker NIR178 combined with the PD-1 inhibitor spartalizumab in advanced non-small cell lung cancer suggest that the drugs are safe. Two of 25 patients showed complete or partial responses, and 13 had stable disease.
Insights
A phase I/II trial of NIR178, an adenosine 2A receptor blocker, plus PD-1 inhibitor spartalizumab showed a safe profile in advanced non-small cell lung cancer. Two patients achieved responses, and 13 had stable disease.
Area of Science:
- Oncology
- Immunotherapy
- Pharmacology
Background:
- Non-small cell lung cancer (NSCLC) remains a leading cause of cancer mortality.
- Novel therapeutic strategies targeting immune checkpoints and tumor microenvironment are crucial for improving patient outcomes.
- Adenosine 2A receptor antagonists represent a promising class of agents in immuno-oncology.
Discussion:
- The combination of NIR178 (adenosine 2A receptor blocker) and spartalizumab (PD-1 inhibitor) was evaluated for safety and preliminary efficacy in advanced NSCLC.
- The study assessed dose-limiting toxicities and determined the maximum tolerated dose (MTD) or recommended Phase 2 dose (RP2D).
- Tumor responses and disease stabilization were recorded as key efficacy endpoints.
Key Insights:
- The combination therapy demonstrated an acceptable safety profile in patients with advanced non-small cell lung cancer.
- Preliminary efficacy signals were observed, with 2 out of 25 patients achieving complete or partial responses.
- A significant proportion of patients (13 out of 25) experienced stable disease, indicating potential anti-tumor activity.
Outlook:
- Further investigation in larger, randomized Phase 2 or 3 trials is warranted to confirm the efficacy of this combination.
- Identifying predictive biomarkers for response could optimize patient selection for this therapeutic approach.
- This combination may offer a new treatment option for patients with advanced NSCLC, particularly those refractory to existing therapies.

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

11.0K
Certain biochemical processes, such as embryonic development and cell growth regulation, depend on the repression of specific genes. DNA binding proteins known as eukaryotic transcription inhibitors regulate the repression of gene expression in eukaryotes. The presence of these inhibitors at the required location and time in the cell is triggered by the presence of hormones and additional signals from other cells.
Eukaryotic transcription inhibitors usually contain two distinct domains, a...

Concrete mixing ensures a homogenous blend where aggregates are well-coated with cement paste. Concrete mixing is typically done using two main types of mixers: batch and continuous. Batch mixers handle one batch at a time, thoroughly combining materials before discharging and receiving the next batch. In contrast, continuous mixers receive a steady flow of ingredients, mixing them consistently and discharging without interruption. Within batch mixers, tilting drum mixers mix with internal...

01:19Mixing Time
483
The concept of mixing time is significant in producing a uniform concrete mix with the required strength. The mixing period starts once all components are in the mixer. Initially, the mixer is charged with 10% of the water, followed by the consistent addition of solids and then 80% of the water. The remaining water is added later, within the first quarter of the mixing period. The minimum mixing time varies according to the mixer's capacity; for example, mixers with up to 1 cubic yard...

368
Ready-mixed concrete, also known as pre-mixed concrete, is prepared in a centralized plant and then transported in trucks to construction sites where it is ready for placement. This type of concrete is categorized into central-mixed, truck-mixed (or transit-mixed), and shrink-mixed. Central-mixed concrete is entirely prepared at a plant and moved to the site in agitator trucks that rotate at a speed of 2 to 6 rpm. Truck-mixed concrete, on the other hand, has the ingredients batched at the plant...
