While it may come as a surprise to majority of people, it holds true. It’s imperative to note, that not every unapproved drug out there can be used in patient treatment, and FDA itself has clear guidelines of when it’s acceptable.

The exception is granted under one of the below conditions:

• The drug is involved in an open drug efficacy study implementation program (DESI)- a program aimed at evaluating the efficacy of drugs that have been on the market prior to 1962
• Healthcare professionals rely on the drug in treatment of serious medical conditions, where there are no drugs available for treatment of this conditions
• There is an insufficient supply of a certain FDA approved drug
• The use is authorized by the U.S. Secretary in diagnosis, monitoring, and treatment of serious conditions in an emergency situation

An individual patient can also request a drug, that is currently unapproved, through a licensed physician. Certain criteria must be met in order to accomplish that:

 

• It must be determined that there is no alternative or comparable treatment currently on the market, and the risk of using the drug/device outweighs the risk from an untreated condition/disease
• A sufficient evidence of safety and effectiveness of the drug through clinical trials
• Use of the drug does not interfere with ongoing clinical investigations to support marketing approval
• The sponsor, or the investigator, submits to the Secretary a description of use of the drug by a single individual, or a group of patients

When it comes to a more widespread use of unapproved drugs in a group of eligible patients, the sponsor, or physician, must prove to the Secretary, that the drug is intended for use in a life-threatening disease/condition, that there is no alternative therapy, that all the necessary clinical trials have been completed, and the sponsor is currently pursuing marketing authorization. Furthermore, a sufficient evidence of safety and efficacy of the drug must be provided.

While it may seem counterintuitive, the use of unapproved drugs is under constant control and very strict regulations from both, the FDA, and the U.S government itself. Each case of use of such drug is thoroughly studied, and the decisions are made on a case-by-case basis by the U.S. Secretary.

Such method of regulation ensures both, a tight enough control over unapproved medications, while still allowing for the special patient needs to be met, in case of an emerging necessity.

Janssen, a pharmaceutical company owned by Johnson and Johnson, and a Russian biopharmaceutical company Nanolek have announced the localization of manufacturing of Darzalex®(daratumumab) in Russia, which is used in treatment of multiple myeloma.

The battle against malignant hematologic diseases has been a strategic direction that Janssen had been working towards for many years now. Our team is diligently working on the search of new molecules, marketing and increasing access to therapy for such debilitating and hard to treat disease as multiple myeloma. This year our innovative product daratumumab was included in a program of high cost nosologies, which gives hope to many patients around the country. In support of this important milestone, we would like to express our commitment to the local Russian strategy, and are delighted to announce a partnership in localization of Darzalex®with one of the progressive Russian producers- biopharmaceutical company Nanolek. We believe that this collaboration will lead to a higher availability of this innovative therapy to Russian patients”, stated Katerina Pogodina, Managing Director of “Janssen” Russia and CIS, Executive Director of “Johnson and Johnson”.

Darzalex®localization is planned at the site of “Nanolek” biomedical center, which is located in Kirovskaya Oblast, in compliance with GMP and ISO.

Vladimir Khrestenko,” Nanolek” president commented: “Today we can talk about global innovations and enormous reserves for extending the life expectancy of the population in terms of availability of treatment for oncologic diseases. Our partnership with Janssen has a large social significance: by joining forces, we can positively contribute to the life of Russian patients living with malignant blood diseases. Our joint localization project will widen the access of patients with multiple myeloma to modern and effective therapy. I’m glad that this collaboration will help to solve one of the most complex medical problems, and aid in improving life expectancy and quality of life of Russian patients”.

Both oncological and vaccination areas are of the primary focus for Nanolek at the moment. The company is actively developing its medication database for treatment of oncological diseases both in collaboration with international companies, and on their own.

In 2017, Darzalex®was registered in Russia and marketed as a monotherapy treatment in patients with relapsing or refractory multiple myeloma. Previous treatment included proteasome inhibitors and immunomodulating substances. In 2019 the drug had a new indication added to its description.

Now, Darzalex® is also recommended as a combination therapy for treatment of adult patients with multiple myeloma. Daratumumab is the first human monoclonal antibody to CD38 protein that has been approved for treating this disease.

Janssen has been contributing to the fight against malignant blood diseases in Russia for over 10 years, by studying molecular and cellular mechanisms of disease development, and by producing and marketing innovative drugs. In 2007, Janssen has made a breakthrough in treatment of multiple myeloma, and the Darzalex® which has appeared on the Russian market in 2017 was acknowledged to be a breakthrough therapy by worldwide regulatory agencies.

Results of a study by INMARK® suggest that early administration of antifibrosis therapy allows to slow down the progression of idiopathic pulmonary fibrosis.

Scientific journal The Lancet Respiratory Medicine published the results of a randomized double-blinded study by INMARK®, which validated the effectiveness of Vargatef (nintedanib) versus placebo in patients with idiopathic pulmonary fibrosis (IPF) for 12 weeks, followed by a 40-week open trial.

INMARK® is a first clinical study that was targeted at evaluating the predictive value of biomarkers in patients with IPF, receiving antifibrosis therapy (nintedanib).

The results showed that even in patients with preserved lung function, a significant difference could be noticed in the rate of reduction of forced vital capacity (FVC) with a 12-week nintedanib versus placebo therapy.

Idiopathic pulmonary fibrosis (IPF) is a rare, chronic and lethal pulmonary disease which affect approximately 3 million people worldwide.

It causes progressive pulmonary fibrosis, leading to permanent and irreversible decrease in lung function and shortness of breath.

Due to the unpredictable progression of IPF and the irreversible decrease in lung function, specialists think that the treatment has to be administered as soon as possible.

INMARK® looked at the rate of change in CPRM, a biomarker, which has previously demonstrated the ability to predict the mortality due to IPF. The level of CPRM was measured from the beginning of the study till 12thweek. The study also measured t the proportion of patients with disease progression defined by the absolute reduction in FVC ≥10%  predicted or dead over 52 weeks.

Nintedanib treatment versus placebo for 12 weeks did not affect the rate of change in CRPM, however was associated with a decrease in the rate lowering of CRPM levels.

29% of patients in the trial experienced an FVC decrease of ≥10% predicted, or died over 52 weeks of follow-up, which demonstrated the progressive nature of IPF even in population with normal FVC value of ≥80%.

Within 12 weeks, patients treated with nintedanib exhibited reduced rate of decline in FVC versus patients receiving placebo (5,9 (18,5) mL/12 weeks in nintedanib group and −70,2 (13,1) mL/12 weeks in placebo group).

“Even in this population of patients with very well-preserved lung function, a difference in FVC decline could be demonstrated between patients treated with nintedanib vs. placebo over 12 weeks of treatment. Considering the unpredictable nature of IPF and the fact that loss of lung function is irreversible the results reinforce a growing body of evidence that early treatment of IPF is the best course of action.” commented Prof Toby Maher, Consultant Respiratory Physician at the Royal Brompton Hospital in London, United Kingdom and principle investigator of the study.

Dr. Susanne Stowasser, Associate Head of Medicine Respiratory at Boehringer Ingelheim, said “Biomarker research is a key driver of modern medicine with huge impact on the understanding of health and disease states, diagnosis, drug development, and prediction of disease course or response to therapy. INMARK was the first clinical trial to investigate the predictive value of biomarkers in IPF patients treated with an antifibrotic. Being poorly understood, IPF has been subject of increasing biomarker research for years with a main focus on identifying markers for prognosis.”

She added: “Pulmonary Fibrosis continue to have a devastating impact on people’s lives. Boehringer Ingelheim is committed to research such as the INMARK trial which helps our understanding of how interstitial lung diseases such as IPF progress in individual patients, and identify those who may respond best to treatment.”

About 3 million Russians suffer from a disease that is considered incurable – hepatitis C.

Despite the fact that over the past few years, the incidence in the country has decreased, about 15 thousand people die from the effects of chronic hepatitis C every year.

The main danger of the disease is in its asymptomatic course.  According to the WHO, only 20% of those infected will find out in time about the diagnosis.

The rest do it until the moment when it is too late to go to the doctor.  A mass vaccination could be the solution to the problem, but there is currently no vaccination.

Therefore, scientists from different countries, including Russia, are working to solve this problem.

Since 2015, a synthetic peptide vaccine against hepatitis C has been developed at the VN Orekhovich Research Institute of Biomedical Chemistry. It is based on artificially created peptide constructs that contain parts of the E2 protein of the hepatitis C virus. This protein is unique in that its antibodies are not detected in  all patients, that is, the immune system for some reason does not recognize it.

In experiments on laboratory animals, these peptide fragments worked perfectly.

They forced the body of mice and rats to produce antibodies capable of binding viral envelope proteins.  That is, the rodent immune system is activated.

Moreover, the scientists thus obtained antibodies were tested on the hepatitis C virus, extracted from the blood plasma of five sick people.  They were also effective against “human” viral particles.

The authors say that if they succeed in choosing the right adjuvant — a complex of substances that boosts the immune response, the antigen dose, route and route of administration — then the resulting drug will be effective precisely against those types of hepatitis C that are common in Russia.
