This document discusses biosimilars, which are biologic products that are highly similar to approved biologic reference products. It provides background on biosimilars, including their development process, advantages, limitations, and future outlook. The development process involves producing a cell line containing the gene for the desired protein, growing cells to produce the protein, purifying the protein, and preparing it for patient use. Biosimilars offer cost savings over biologics but have concerns around immunogenicity and long-term effects when switching between products. The global biosimilar market is expected to grow significantly as biologic patents expire and more companies develop biosimilar versions of treatments.

Lung Cancer: Artificial Intelligence, Synergetics, Complex System Analysis, S...Oleg Kshivets
RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.
New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

4. INTRODUCTION
Biologics are derived from the natural resources such as human, animal, or
microorganism and manufactured by various biotechnology methods such
as recombinant deoxyribonucleic acid technology, controlled gene
expression, and antibody technology.
Biosimilar is a biologic product, which is very similar to Food and Drug
Administration (FDA)-approved biological product known as reference
product and has no clinically meaningful differences in term of safety and
effectiveness from the reference product.

5. CURRENT STATUS
The first biosimilar, Omnitrope (a recombinant human growth was), was
approved in Europe by the European Medicines Agency (EMA) in 2006.

CHEMICAL MEDICINE:
• Generally high molecular wieght
• Made wit/from live cells/organisms
• –inheritance and contamination risk
• Many critical process steps
• Less easily characterized
• Structure may or may not be
completely defined or known
• Hetegenous mixtures – may include
variants
• Often immunogenic

9. BIOSIMILARS IN CLINICAL PRACTICE
Biosimilars in clinical practice:The use of biosimilars is essentially a
change in clinical management.By taking a leading role in educating
patients and medical professionals about the risks and benefits of
biosimilars.
The role of hospital pharmacists :It is of utmost importance that the
hospital pharmacist is aware that the innovator products and biosimilars
are not interchangeable, because patients must be carefully monitored if
their treatment is changed between products. Moreover, patient welfare
is foremost and for pharmacists, the knowledge that biosimilars are not
generics, and the possible implications for clinical outcomes when
products are switched, will help ensure patient safety.Additionally,
biosimilars are deemed to contain a new active ingredient, whereas
interchangeable products are not.
The role of nurses in the use of biosimilars

10. Stages:
1. Producing the master cell line containing the gene that makes the desired
protein.
The genetic code (a sequence of DNA) of a selected protein (e.g. a
hormone, antibody, blood product) is identified and a functional DNA
sequence created.
The genetic code is inserted into various host cell lines (e.g. bacteria or
yeast), so that the host cells produce this protein.
The host cell line that produces the protein the most successfully becomes
the chosen host cell line.
2. Growing large numbers of cells that produce the protein in machines called
bioreactors; this process is called fermentation.
3. Isolating and purifying the protein, separating it out of the bioreactor via a
filtration process.
4. Preparing the biologic for use by patients (stabilizing and processing).
5. More patents on the process than on the drug.

12. ADVANTAGES AND LIMITATIONS
Advantages:
• Treatment cost with biosimilar is lesser than innovators biological drug.
• Biopharmaceuticals represent one of the fastest-growing segments of
pharmaceuticals industry and by 2011, they are expected to represent 50% of
the market.
• Patent of original product is going to expire and therefore opportunity for
generic versions of biopharmaceutical is very large.
• The operating profit margin of traditional generic drugs is roughly 20%, but
depending on the biosimilar product, profit margins have the potential to be
somewhat higher, as much as 30%.
Limitations:The main concerns raised regarding biosimilar are immunogenicity,
efficacy, adverse effects when switching from a biologic to a biosimilar , and
possible long-term effects. This issue has been well documented in two recent
2017 trials, comparing the implications of switching from an infliximab
innovator to biosimilar , over the span of one year in IBD patients.
12
13. FUTURE PERSPECTIVE
• Many companies will have their patent expire in the forthcoming year,
which will open the window of opportunity for other biopharmaceutical
companies to explore the possibility of development of biosimilar
products.
• The global market for the biosimilar is expected to grow by US$10 billion
and many companies are anticipated to enter into this lucrative sector.
• Although the biosimilar space is still growing and evolving in the United
States, India is a significantplayer in the world in manufacturing and using
of biosimilars.
• Indian biosimilar market was approximately US$300 million in 2015. The
domestic sales are close to US$250 million and growing at a compound
annual growth rate of 14%. The export of biosimilar or similar biologic
from India stands at a staggering US$51 million.
• India has the potential to become a global player in similar biologics or
biosimilars
13
14. CONCLUSION
Biosimilars hold promise to improve patient’s accessibility for many
malignant and nonmalignant ailments by reducing the treatment cost.
Since the use of the first biosimilar, the development and uses of
“biosimilars or similar biologics” have witnessed substantial growth. Every
year, regulatory agencies are granting approval of various similar biologics
for the treatment of many cancerous and noncancerous diseases.
India has firmly established itself as a global player as a maker of
similar biologics. It is also a huge market for the similar biologics because
of its burgeoning population. Although the potential is high and
expectation is huge for India, the challenges are also enormous and
daunting to maintain the leadership.
