The Hatch-Waxman Act established an Abbreviated New Drug Application (ANDA) process that allows generic drug companies to piggyback on the safety and efficacy data of branded drugs. It provides incentives for generic drug development and challenges to drug patents. The Act requires patent information be listed in the Orange Book and ANDA applicants must make one of four certifications regarding patents. A Paragraph IV certification for patent invalidity or non-infringement can lead to a patent challenge and 30 month stay of FDA approval for generics. The Act benefits both branded and generic drug companies.

Hatch- waxman act (The drug price competition and patent term restoration act...Mohit Kumar
The Drug Price Competition and Patent Term Restoration Act , informally known as the Hatch-Waxman Act, is a 1984 United States federal law that encourages the manufacture of generic drugs by the pharmaceutical industry and established the modern system of government generic drug regulation in the United States.
This generally deals with ANDA litigation in United states with Paragraph iv litigation generally. It also emphasizes on Cost involved in ANDA litigation with different methods for reducing the cost.and how many million or billion at stake when Generic and Branded drugs. It also covers the litigation part of District New Jersey that how and in what manner litigation with respect to Hatch-waxman act an is done along with the timelines and CAFC timelines.
Regarding the objectives of the act , drug approval that includes both the branded drug and the generic drug approval, new drug exclusivity, about the challenging patent exclusivity, patent term extension and patent litigation under the act ,and the benefits of branded manufacturers will be discussed here .
The presentation aims at a students focussed perspective of Abbreviated New Drug Application filing with premier regulatory body like USFDA, the eCTD is followed worldwide for drug submission aimed for gaining particular market approvals.When submitted with FDA it is evaluated by CDER. eCTD is further a mandatory submission for ANDAs with FDA and for NDAs with EU and Japan.
Drug Price Competition and Patent Term Restoration Act.
The Hatch-Waxman Act was created in response to a court case called Roche Products, Inc. v. Bolar Pharmaceutical Co., which involved a drug called flurazepam. Roche owned flurazepam, and Bolar was seeking to sell a copy after Roche’s patents expired. Bolar was hoping to time the approval with the expiration of the patents and began work on drug development activities.
The Drug Price Competition and Patent Term Restoration Act of 1984, commonly known as the Hatch-Waxman Act, addressed each of these concerns. Through amendments to both the patent law and the food and drug law, the Hatch-Waxman Act established several practices intended to facilitate the marketing of generic pharmaceuticals while providing brand-name firms with incentives to innovate.

Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.

From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path
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
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!

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.

Introduction
Objectives of the act
Provisions of the act
Orange book
Types of patent certification
Para IV- patent challenge
Incentives and protection
Para IV deadline
Delay in generic entry
3. INTRODUCTION
It is Also known as “THE DRUG PRICE COMPETITION
AND PATENT TERM RESTORATION ACT”
Enacted in 1984 .
Amended the patent laws
Before 1962- new drug approval based on safety alone
In 1962-proof of efficacy made compulsory for marketing
approval of a new drug (Kefauver-Harris Amendments)
There was no provision for patent term extension prior to
enactment of the Hatch Waxman Act, to make up for the time
lost out of the total patent term during the marketing approval
process
4. CONT…
Generic companies required to submit their own comprehensive
NDA
Costly
Time consuming
If drug was covered by patent ,Testing could not begin until
patent expired.
To overcome the above problems an act was needed to promote
generic companies
5. OBJECTIVES
Reducing the cost associated with the approval of a generic
drug
Allowing Early-Experimental-Use
Compensating the branded drugs manufacturers for the
time lost from the patent term because of the regulatory
approval formality
Motivating the generic drug manufacturers
6. PROVISIONS
Creation of section 505(j)
Section 505(j) established the ANDA approval process
The timing of an ANDA approval depends in part on patent
protections for the innovator drug
NDA must include any patent that claims the "drug" or a
"method of using [the] drug" for which a claim of patent
infringement could reasonably be asserted
On approval of NDA, FDA publishes patent information for
drug in Orange Book (“Approved Drug Products with
Therapeutic Equivalence Evaluations”)
7. ORANGE BOOK
FDA publishes patent information on approved drug products in
the Orange Book
An NDA applicant must submit the following information for
each patent:
Patent no and date on which the patent will expire
Type of patent, i.e. drug, drug product, or method of use
Name of patent owner
The name of an agent of the patent owner or applicant
Brand drugs listed for generics to compare with their proposed
products
8. TYPES OF
PATENT
CERTIFICATION
When an applicant submits an ANDA to the FDA, the applicant
must certify one of four things under section 505(j)(2)(A)(vii):
That the required patent information relating to such patent has
not been filed (Para I) ;
That such patent has expired (Para II) ;
That the patent will expire on a particular date (Para III);
That such patent is invalid or will not be infringed by the drug,
for which approval is being sought (Para IV – Patent
Challenge)
9. PARAIV- PATENT
CHALLENGE
GENERIC- para IV filing
GENERIC- provide notice to brand within 20 days of
acceptance
BRAND- must bring lawsuit within 45 days
GENERIC- if sued, automatic 30 month stay granted to
BRAND
11. INCENTIVES
AND
PROTECTION
180 day market exclusivity:
First applicant to submit a substantially complete ANDA (first
to file)
30month stay of FDA approval:
If patent owner or NDA holder sues the ANDA applicant for
patent infringement within 45 days of receiving notice of the
Paragraph IV certification
Runs from date of notification or expiration of NCE exclusivity
May be lengthened or shortened by the court
12. PARA- IV
DEADLINES
NOTIFICATION LETTER : 20 DAYS
Upon ANDA acceptance for filing, the applicant must notify the
NDA holder and patent owner of the ANDA within 20 days.
The notice must include a detailed statement of the factual and
legal basis of the opinion of the applicant that the patent is
invalid or will not be infringed
LAWSUIT: 45 DAYS
Upon notification, the NDA holder and patent owners have 45
days in which to initiate an action for patent infringement. If
such an action is brought within 45 days, the ANDA is subject
to a 30-month stay of FDA approval beginning on the date the
notification letter was received
13. BENEFITSFOR
BRANDED
MANUFACTURER
Orange Book provides public notice of patents
Allows for resolution of patent disputes prior to generic entry
30-month stay of FDA approval of generic drugs
Patent Term Restoration
Allows for Several Market Exclusivities:
Data Exclusivity
5 years for New Chemical Entity (NCE) Drug
3 years for non-NCE Drug
Orphan Drug (7 years)
Pediatric (PEDS) (6 months)
14. BENEFICTSFOR
GENERIC
MANUFACTURES
180-day market exclusivity for first successful challenger to
Orange Book patent
Allows generics to challenge Orange Book patents without risk
of damages
“Safe Harbor” rule allows generics to perform bioequivalence
and other testing relating to regulatory approval without risk of
patent infringement
16. REVERSE
PAYMENT
AGREEMENTS
Both parties decide it is in their mutual best interests to settle
via a significant payment from the patent owner/branded to
the generic to keep the generic drug off the market
The generic may make more money than by rushing to
market the drug
The branded may also make more money by paying the
generic to defer marketing the drug for a certain period of time
17. SHAM
LITIGATIONS
Brand sues generic for patent infringement
Court finds for generic, often on SJ, and holds patent invalid or
unenforceable
Hatch-Waxman 30-month stay allows brand to win even if they
lose
Plaintiffs must prove brand’s infringement suit is objectively
and subjectively baseless
18. SHAM CITIZEN
PETITIONS
Companies can petition FDA to not approve an ANDA
Should be based on safety or formulation concerns
Citizen’s Petitions delay approval of ANDAs
Ripe for abuse, and often abused
Delay itself is the goal
Same standard as Sham Litigation
19. WALKER
PROCESS
Antitrust violation premised on fraud on the PTO
Patent applicants have a duty of candor to PTO because
applications are ex part
Elements track fraud claims
Often coupled with Sham Litigation and other theories
20. PRODUCT
HOPPING
Delay sometimes allows brands to introduce new versions of
the product
Changes are often minimal but can defeat generic competition
Brands actively convert the market
– Free samples
– Pulling the “old” product from the market
