Moderna’s next steps in Korea…vaccine production scenarios
by
Kim, Jin-Gu
May 06, 2021 06:07am
The establishment of Moderna’s Korean subsidiary has begun. Moderna's business team from its U.S. headquarters had visited a factory of a domestic pharmaceutical company. The company's actions are adding strength to the speculation that domestic production of Moderna's vaccines is imminent. The factory that the business team had visited the previous month is expected to act as an outpost for Moderna’s vaccine production. On this, various scenarios on whether Moderna will directly take charge of vaccine production in Korea or will contract a domestic company to produce the vaccine are being raised in the industry. ◆'Establishment of ‘Moderna Korea’ … why enter Korea? According to industry sources on the 3rd, Moderna had posted an announcement on its website to hire a GM (General Manager) for Korea. Industry officials interpret this as the company's first step into establishing subsidiaries in Korea, Japan, and Australia as stated by the compnay on the 15th last month. The most likely purpose for entering Korea is to produce COVID-19 vaccines. Moderna has been producing 500 million doses of its vaccine annually at its U.S. and European plants. However, the whole amount of the vaccines produced by the two plants are being supplied locally. The production amount of the two plants is said to be tight and is just enough to meet the local demand. Therefore, vaccines for other regions must be produced in other factories. This is also true for the 20 million doses that the company agreed to supply to Korea. Moreover, in the case of the United States, the Defense Production Act fully controls the export of raw materials and equipment used in the production of COVID-19 vaccines, which gives strength to the theory that Moderna will produce vaccines in Korea. Moderna had posted a job announcement on its website to hire a GM for Korea. ◆Why Moderna’s business team visited A Pharmaceutical’s plant In mid-April, a business team from Moderna headquarters visited a plant of a domestic pharmaceutical company, A Pharmaceuticals. "I know that Moderna 's HQ visited and inspected A Pharmaceutical's plant and manufacturing facilities around 2 weeks ago,” said an industry official. However, whether the company has visited plants of other pharmaceutical companies remains unknown. Some are interpreting the visit as Moderna's move to secure a base for the domestic production of its vaccine. However, whether Moderna will be directly producing the vaccine, or will consign its production to a domestic company has not been decided yet. ◆Direct manufacturing or CMO… three possible scenarios The industry has been pushing three scenarios based on the two facts mentioned above. The first scenario is where Moderna takes over the A company’s plant to directly produce its vaccine. mRNA vaccines are largely manufactured in three steps. raw material manufacturing → lipid nanoparticle coating → finished product manufacturing. The key technology in the production of mRNA vaccines lies in the lipid nanoparticle coating process. When injected, mRNA quickly degrades in the body, therefore, the technology that surrounds it with lipid nanoparticles to keep it intact for a long period of time is important. Moderna has been known to pay extreme attention to the security of this technology. It has been using the direct production method to prevent technology leakage in the U.S. and Europe. On the surface, the company has signed a CMO deal with Lonza, a Swiss-based global CMO company, but then directly invested 70 million francs (about 86 billion won) and 40 million francs (about 49 billion won), in the U.S. and Swiss factory respectively. The industry views it as no different from direct production. In the same way, Moderna may start direct production of its vaccine by acquiring a share of a plant in Korea. The second scenario is that Moderna will make a CMO deal with a domestic company to produce the vaccine. Usually, global pharmaceutical companies do not use their own factories when establishing Korean subsidiaries. Most of the companies receive ‘import permits’ rather than ‘ manufacturing permits’ upon their establishment. Rather, in recent years, the trend has been for the subsidiaries to withdraw the already-established factories. Most recently, Janssen, as well as Bayer, Novartis, Abbott, Pfizer, Boehringer Ingelheim, Roche, and MSD previously had also withdrawn operation of their plants. This is why some believe that Moderna, like other companies, will not set up a factory in Korea. For Moderna, which owns only one type of vaccine, the factory is likely to remain a nuisance after COVID-19 ends. Accordingly, some speculate that the vaccine will be developed under a CMO deal with a domestic company. However, whether Moderna will make a technology transfer deal or participate in production by acquiring some of the domestic company’s shares is unknown. The third scenario is that Moderna will dualize the manufacturing process. Moderna will take charge of the core process, and then consign a domestic company for the last step, the fill&finish process. GC Pharma is a prominent candidate for Moderna's filling and packaging process. GC Pharma has already been selected as a CMO for COVID-19 vaccines by CEPI (Coalition for Epidemic Preparedness Innovations), a global private organization, in October last year. GC Pharma's manufacturing will take place in its Ochang plant, and the company plans to fill and finish more than 500 million doses. In addition, GC Pharma already has ties with Moderna. It has already signed a contract for the domestic approval and distribution of the Moderna vaccine. In this scenario, after the raw material is manufactured by Moderna and A Pharmaceutical company, filling, finishing and domestic distribution of the finished product would likely be handled by GC Pharma based on the relationship already established between the two companies.

We must do our best to develop domestic vaccines
by
Lee, Jeong-Hwan
May 06, 2021 06:07am
President Moon Jae-in received a report on the 3rd that "The introduction and vaccination of COVID-19 vaccine is faster than originally planned, and if the amount of introduction by time is as efficiently as possible, the vaccination target for the first half could be raised from 12 million to 13 million. " President Moon presented an opinion that after successful formation of collective immunity this year, and all efforts should be devoted to developing domestic vaccines next year. In the afternoon of that day, President Moon at COVID-19 Response Special Quarantine Inspection Meeting (at the main building of Cheongwadae) said, "Korea has already secured twice as much vaccine as the public, and has exceeded the goal of inoculating 3 million people by the end of April by more than 10%." President Moon ordered that the goal of achieving collective immunity in November be brought ahead of the plan and correct misinformation so that the public would not be anxious. President Moon said, "Even in May, Pfizer vaccine will be supplied stably to Korea every week, and AstraZeneca vaccine will also be delivered in larger quantities than originally planned. The government is most effectively distributing the amount of vaccines introduced into the first and second vaccinations according to a meticulous plan.” He added, "Please make the best use of private medical resources for vaccination, and increase the autonomy and accountability of a local government." President Moon emphasized that efforts should be made to develop vaccines in Korea. He said, "Securing vaccine sovereignty is the most important task in the global competition for vaccine security. Please do your best to use the domestic vaccine developed by our company next year." He said, “Korea is attracting attention as a country that can become a global hub for vaccine production. It has the world's second largest biopharmaceutical production capacity, and currently, three COVID-19 vaccine products developed overseas are produced by consignment or technology transfer in Korea. He said, "For the goal of becoming a global hub country, public-private partnerships will cooperate and provide administrative and diplomatic support." He explained, "The number of confirmed COVID-19 patients is 600-700 every day. Fortunately, the number of confirmed cases is still very small compared to the population, and the fatality rate is incomparably low compared to that of major countries." He said, "With successful quarantine, the economy is recovering rapidly and vaccination is in progress. There is also hope for a daily recovery." He repeatedly emphasized, "If people trust the government and cooperate with quarantine and vaccination, we will accelerate our return to our precious daily lives."

Second Vice Minister of Health and Welfare Kang Do-tae visited a public health center in Yongsan-gu, Seoul on the 3rd and received the AZ vaccineThe health and quarantine authorities and the head of the KMA met together to get the AstraZeneca (AZ) COVID-19 vaccine and agreed to overcome COVID-19. Kang Do-tae, the second vice minister of the MOHW, visited COVID-19 Vaccination Center in Yongsan-gu, Seoul on the 3rd to check the vaccination progress and encouraged the officials. Vice Minister Kang checked the vaccination progress and vaccination movements at the vaccination center, and listened to the difficulties and suggestions of the vaccination subjects and those involved in the field. In particular, Vice Minister Kang said, "We will do our best to manage the vaccine for the safe and rapid vaccination of the people, and cooperate with local fire departments and emergency medical institutions to ensure that there is no lack of a response system for adverse reactions that may occur after vaccination." After visiting the vaccination center, Vice Minister Kang visited the Yongsan-gu public health center and received AstraZeneca vaccine with Minister of the MFDS Kim Kang-rip and Lee Pil-soo, chairman of the KMA. The 2nd Vice Minister Gang-tae (right) and Lee Pil-soo, the new president of the medical association, are shaking hands Lee Pil-soo, the new chairman of the KMA, said, "As a representative of the medical field, we volunteered to alleviate public concerns and anxiety about vaccines and show our will to end COVID-19 as soon as possible." He said, "The KMA and 130,000 members are doing their best to vaccination against COVID-19 to protect the health and lives of the people, and the government, the public, and medical personnel will work together to overcome COVID-19 together." Minister of the MFDS Kim Kang-rip asked special attention, such as observing storage temperature, so that the quality could be maintained continuously during the process of receiving and storing the vaccine, examining the storage status of the vaccine. He also said, "The domestically approved COVID-19 vaccine is thoroughly verified for safety and effectiveness through triple expert consultation at the MFDS. The benefits far outweigh the risks caused by the vaccine, and as it is a vaccine approved by the MFDS, we hope that the people will be vaccinated with peace of mind." Vice Minister Kang expressed his gratitude for the cooperation and hard work of local governments and the medical community in the process of responding to COVID-19. He said, "Vaccination is a safe and effective preventive method, and I hope that the public believe in the government and experts and inoculate them in order for the health of themselves, their families and neighbors."

Eli Lilly applies for reimbursement of Emgality in Korea
by
Eo, Yun-Ho

The new migraine treatment ‘Emgality’ is seeking reimbursement benefits in Korea. According to industry officials, Eli Lilly Korea has recently submitted a reimbursement application for its calcitonin gene-related peptide (CGRP)-targeted migraine prevention therapy ‘Emgality (galcanezumab).’ Emgality, the first CGRP-targeted migraine prevention treatment to be introduced in Korea, selectively binds to CGRP, a substance known to be a key cause of migraine, and blocks its binding to the receptor. The drug was designated as an orphan drug in April of last year and approved in September of the same year. Recently, Emgality was additionally approved by the FDA as a treatment for episodic cluster headaches. Emgality had received much attention as a promising drug in the field of migraine along with ‘botulinum toxin.’ However, as a non-reimbursed drug, the demand for better access to the drug has been rising. If approved, the reimbursement is expected to have a significant impact on the migraine market. Emgality had passed the drug committee (DC) in major general hospitals in Korea including the Seoul National University Hospital and Severance Hospital. Lilly Korea and SK Chemicals have been co-promoting Emgality in Korea. With ‘Ajovy (fremanezumab),’ another CGRP-targeted therapy, soon to enter the Korean market, attention is on how the migraine treatment market will be reorganized in the future. The approval was based on results of the EVOLVE-1 and EVOLVE-2 trials which involved 1,773 patients with episodic migraines for 6 months, and the REGAIN trial which involved 1,113 patients with chronic migraines (at least 15 headaches a month for at least three months) for 3 months. Results of the two trials on episodic migraine patients comparing the MHDs per month over a 6-month period showed that compared to baseline (Emgality group 9.2 and placebo group was 9.1), Emgality demonstrated efficacy over placebo in treating migraines. In particular, in the EVOLVE-2 trial that involved Korean patients, the mean MHDs per month was reduced by 2 more days during the 6-month period in the Emgality group (226 patients) compared to the placebo group (450 patients) (Emgality 4.3 days vs. placebo 2.3 days). Also, 59% of patients treated with Emgality (compared to 36% in the placebo group) saw a 50% reduction in MHDs over the 6-month period. 34% (18% for the placebo group) saw a 75% or more reduction, and 12% (6% for the placebo group) saw a 100% reduction in MHDs. “Emgality showed a migraine prevention effect from the first week. Episodic migraines patients who experienced migraines 4 to 14 days a month have experienced a reduction by half compared to before treatment, and 1 in 7 patients showed a 100% response rate,” said Professor Min-kyung Joo of the Severance Hospital. “The drug may bring a big difference to patients who have been struggling to maintain their daily and social life due to migraines.”

Samyang Holdings is expanding generics for anticancer drug
by
Lee, Tak-Sun
May 04, 2021 05:55am
Last month, Samyang Holdings, which merged with Samyang Biopharm, a subsidiary specializing in pharmaceutical bio, is expanding generics for anticancer drug business. In January, following generic for Votrient (Pazopanib HCl), a kidney cancer treatment, it is also developing generic for Sutene (Sunitinib Malate). Votrient and Sutene currently do not have generics in Korea. The MFDS approved the protocol of bioequivalence study for SYO-1767 applied by Samyang Holdings on the 30th of last month. SYO-1767 is presumed to be generic for Sutene in that the target disease name of this drug is the same as Pfizer's Sutene. Sutene, which was approved in Korea in 2006, is used for various carcinomas such as gastrointestinal stromal tumor, renal cell carcinoma, and pancreatic endocrine tumors. As of last year's IQVIA, Sutene's sales amounted to ₩13.9 billion, more than its rival Novartis Votrient's ₩12.6 billion. In particular, Sutene's patent expired on February 15th. Samyang Holdings is the first to develop generics in Korea. Generic for Votrient by Samyang Holdings was approved in January for a bioequivalence test, and Votrient's patent expires in 2022. It is analyzed that if Samyang preoccupies generics for Sutene and Votrient , it will be in high demand, especially in the kidney cancer treatment market due to its rarity and low price. Samyang has confirmed its competitiveness in the domestic market through anticancer drugs such as Genexol (Paclitaxel), which has been successfully localized. It has successfully commercialized the hemoamac treatment Bendalid (Bendamustine) and breast cancer treatment Everose (Everolimus), targeting the original market. Recently, it started the pharmaceutical business after the merger, such as developing mCureX and mRNA COVID-19 vaccine. Samyang Holdings held a board meeting in January and decided on the agenda for the merger and acquisition of Samyang Biopharm. At the time, Samyang Biopharm was a wholly owned subsidiary of Samyang Holdings. The merger and acquisition was completed on the 2nd of last month, which is expected to strengthen the competitiveness of the pharmaceutical bio business and increase management efficiency. In particular, it is evaluated that stable procurement and investment of drug development resources has become possible.

MFDS designates 3 new orphan drugs including asciminib
by
Lee, Tak-Sun
May 04, 2021 05:55am
On May 3rd, the Ministry of Food and Drug Safety (MFDS) newly designated 3 drugs including ‘asciminib,' which is used for the treatment of rare leukemia and breast cancer, as orphan drugs. Also, MFDS announced that it will extend the indication for ‘ibrutinib,’ and designate drugs used for neonatal hypoxic-ischemic encephalopathy as development-stage orphan drugs. The orphan drug designation is given by the Minister of Food and Drug Safety, to drugs that are used to diagnose or treat rare diseases with no alternatives or with a significantly improved safety and efficacy compared to existing alternatives. The MFDS operates the ‘orphan drug designation system’ to promptly facilitate the approval process of orphan drugs by setting the data, criteria, and conditions for approval for each disease separately according to its characteristic, to support the development of rare and incurable diseases. "We hope the new and expanded designation of orphan drugs set out today will contribute to the development of treatments for patients with rare and incurable diseases,” said an official from MFDS. “We will continue to prepare policies to guarantee treatment opportunities for our patients in Korea.”

Combination of Forxiga + Januvia was applied for permission
by
Lee, Tak-Sun
May 04, 2021 05:55am
MSD It was found that two companies applied for a combination drug license that combines Forxiga (Dapagliflozin Propanediol Hydrate, AZ), a SGLT-2 inhibitory family, leading the diabetes treatment market, and Januvia (Sitagliptin Phosphate Hydrate, MSD), a DPP-4 inhibitory class. Combination of Forxiga+Januvia has not yet been approved in Korea. It is expected that market success is expected if commercialized. According to the MFDS on the 30th, a combination of Dapagliflozin Propanediol Hydrate (10mg)-Sitagliptin Phosphate Hydrate (100mg) was applied for approval on the 30th of last month and the 1st of this month. Dongkoo recently applied for the same ingredient to the MFDS. As Donggu Bio has signed consignment contracts with about 20 pharmaceutical companies, it may be a consigned pharmaceutical company, or it may be a pharmaceutical company that has been pursuing development alone. The applied indications are ▲When Sitagliptin alone cannot control blood sugar sufficiently, ▲When Dapagliflozin alone cannot control blood sugar sufficiently, ▲If Metformin alone cannot control enough blood sugar and it is difficult to control enough blood sugar with two-drug therapy, ▲If sufficient blood sugar control cannot be achieved with Metformin and sitagliptin combination therapy, Metformin and this drug are administered concurrently,▲ if Metformin and Dapagliflozin cannot sufficiently control blood sugar due to combination therapy, Metformin and this drug are administered together, and ▲ it is administered when replacing Dapagliflozin and Sitagliptin combination therapy. Currently, the SGLT-2+DPP-4 combination drug has been approved mainly for imported drugs, but there are no items that are still covered, so it is difficult to estimate the size of the market. The market is expected to achieve expected sales if the benefit is applied because the ratio of prescriptions for both drugs is already high. Even after obtaining permission due to the patent registration of the original drug, it is impossible to sell it on the market right away. This is because Januvia's product patent ends on September 1, 2023, and Forxiga's product patent is scheduled to expire on April 7, 2023. Moreover, since Forxiga is also valid for subsequent patents, generics must succeed in the challenge of subsequent patents in order to be released after the product patent expires. Forxiga and Januvia are leading items that are gaining popularity in the diabetes treatment market. As domestic generic companies have not yet participated in the DPP-4 and SGLT-2 markets, dozens of pharmaceutical companies are expected to participate in product development.

Kim, Jung-Ju
May 04, 2021 05:55am
SK Chemicals' self-developed hemophilia treatment Afstyla (Lonoctocog Alfa (blood coagulation factor VIII, genetic recombination) ) finally passed the Health Insurance Policy Committee. It took 15 months after obtaining a domestic permit and one year after applying for insurance registration. The start of benefits was set on June 1, when supply was available, and the price was set at ₩625 per IU. The MOHW announced that the amendment (draft) of the Pharmaceutical Benefit List and benefit upper limit price table', which provides benefits for Afstyla, was submitted to the agenda of the Health Insurance Policy Committee during the day (30th), and that both deliberation and resolution were passed. .This drug is a hemophilia A treatment developed by SK Chemicals, and it was exported to CSL in Australia in 2009 .This drug applied for insurance registration to the HIRA on April 29, about three months after obtaining approval from the MFDS on January 20 last year .The HIRA held the Pharmaceutical Benefits Advisory Committee on December 3 of the same year for deliberation .This drug was introduced as a gene recombination product among factor VIII replacement therapy in textbooks such as Hemostasis and Thrombosis Advisory and recommended for use in clinical guidelines .In terms of cost-effectiveness, the weighted average price of the alternative drugs Blood Coagulation Factor VIII, Recombinant (ADVATE), Moroctocog Alfa (Xyntha Solofuse Prefilled Inj.), Beroctocog Alfa (Greengene F), Efmoroctocog alfa, and Rurioctocog alpha is less than ₩625 per IU .It was judged to be cost effective .In the case of biopharmaceuticals, if they accept the weighted average price or less, they are classified as drugs that omit drug price negotiations, so negotiations are exempted .Related conferences such as The Korean Society on Thrombosis and Hemostasis and The Korean Society of Hematology also commented that the effect was comparable to that of conventional drugs and improved convenience by reducing the number of administrations .When looking at the listing status of excluded countries, it was listed in the United States, Italy, Japan, Switzerland, and Germany in five of the A7 .The adjusted average prices in these countries range from ₩1274.72 to ₩1350.89 per IU . Accordingly, the Pharmaceutical Benefits Advisory Committee decided that if the alternative drug was accepted below the weighted average price, the company would accept it and skip the negotiation, and only negotiate the estimated billing amount with the NHIS from January 19th to 19th of this year .As a result of the negotiations, the two sides agreed to an estimated billing amount of ₩5.6 billion, taking into account the market share reflecting clinical usefulness .The NHIS predicted that there would be no additional fiscal requirements as alternative drugs exist .The items are 250, 500, 1000, 2000, 3000 IU, and the price is ₩625 per IU .The MOHW decided to apply insurance benefits as of June 1, taking into account the availability of supply from the company .CSL Behring Korea Ltd will sell this product, and SK Chemicals is receiving royalties and sales milestones from global sales .

MFDS, "will make all efforts to pass and land the 1+3 bill"
by
Lee, Jeong-Hwan
May 03, 2021 05:54am
The Ministry of Food and Drug Safety announced its plan to pass the revised Pharmaceutical Affairs Act at the National Assembly's plenary session and soft-land the system afterward. The revised Act contains a clause that limits the number of consignees to three for each company that conducts the bioequivalence test for generics and drugs requiring data submission (incrementally modified drugs, iMD). The Ministry also reaffirmed its position regarding the 1+3 bill for generics and IMDs, on how the bill will partially resolve the rampant drug production issue in Korea, and have a positive influence on preventing recurrence of GMP violations of domestic pharmaceutical manufacturers like Binex and Vivozon. In addition, MFDS said it will actively increase its manpower to systemize and operate the 'GMP Special Planning Inspection Team' at all times through discussions with the Ministry of Public Administration and Security. The answers above were provided on May 1st as a response to the written questions sent by the members of the National Assembly's Health and Welfare committee, In-soon Nam, Yeong Suk Seo, and Hye-young Choi of the Democratic Party of Korea. The three lawmakers questioned the MFDS on the countermeasures against GMP violations of domestic pharmaceutical companies, its position on the 1+3 regulation bill, and the direction the domestic pharmaceutical industry should pursue. On the reason why domestic pharmaceutical manufacturers intentionally violate GMP when producing drugs, MFDS pointed to ▲ financial reasons, such as the time and cost of receiving approval for changes ▲ the internal perception that violations are okay as long as the company avoids drug surveillance and ▲ the small scale of punishment. As for countermeasures to prevent recurrences, the MFDS will continue to conduct random spot inspections with the GMP Special Planning Inspection Team while improving the system, with measures such as increasing the punitive fines and implementing one strike-out system for the GMP acceptance test. In particular, the MFDS responded that it was “necessary” to operate the GMP Special Planning Inspection Team at all times. Also, the Ministry added that it will actively implement policies to increase MFDS personnel to allow the Special Planning Inspection Team to operate at all times. “We are grimly aware of the illegal activities conducted by pharmaceutical companies that should have been tending to public health. This is not a universal problem in the industry, but still, we are operating random spot inspections at all times in case similar cases arise,” wrote MFDS. “We believe a year-round operation of the Planning and Inspection Team is necessary to prevent illegal activities in advance.” Also, it wrote, "We will actively discuss measures to increase personnel in local governments with relevant ministries including the Ministry of Public Administration and Security," adding that the Ministry "asks for active support from the National Assembly.” Regarding the bill that restricts sharing bioequivalence and clinical data between companies to prevent rampant production of generics and IMDs, the MFDS strongly agreed on the need for its legislation and promised to make every effort to implement the post-revised system. On the question of how to strengthen the competitiveness of the domestic pharmaceutical industry, the MFDS responded that it intends to make efforts to build a development-oriented pharmaceutical industry by reducing the development period and cost of drugs through measures such as providing advice on clinical trials, technical support after authorization, and training professional manpower. “The domestic pharmaceutical industry has been continuing its efforts to invest in R&D to produce new products, however, the current circumstances are not enough to reorganize the current sales structure that is focused around generic sales competition,” wrote MFDS. “We will foster a development-focused industry environment. The 1+3 bill is one of the measures that may improve the quality of drugs while preventing rampant drug production, so we will do our best to pass the bill at the plenary session.”

Hanmi launched a new challenge for patent of Entresto
by
Kim, Jin-Gu
May 03, 2021 05:54am
EntrestoHanmi took a new challenge in patenting the heart failure treatment Entresto (Sacubitril/Valsartan). It was already challenging other patents and requested an invalidation trial for a more difficult patent. If Hanmi succeeds in overcoming its patent on its own, it is expected that it will be able to release generics earlier than other companies. According to the pharmaceutical industry on the 3rd, Hanmi filed a trial against Novartis on the last day of last month for invalidation of composition and use patent of Entresto. This patent is known to be the most difficult to overcome among the four patents listed as Entresto. Patents registered as Entresto are ▲use/composition patent expiring in July 2027 ▲crystalline patent expiring in September 2027 ▲composition patent expiring in November 2028 ▲composition patent expiring in January 2029. The use/composition patent that expire first are in fact playing the role of product patent. Entresto is a heart failure treatment with the addition of Valsartan, an ARB-series hypertension treatment, and Sacubitril, an NEP inhibitor series, another treatment for hypertension. With the expiration of each patent, Novartis conducted a clinical trial by combining the two active ingredients, and was licensed as a treatment for heart failure. The reason that Hanmi newly challenged the most difficult patents to overcome is to preoccupy the generic market. Earlier, 20 companies, including Elyson, have requested a trial to confirm the scope of passive rights for a crystalline patent that expires in September 2027. This included Hanmi. If they overcome the patent, it was possible to release generics after July 2027. If Hanmi additionally overcomes the patent, it will receive generic for exclusivity, and will be exclusive for 9 months regardless of the success of challenges such as Elyson. The key is whether other companies will join the challenge. if an invalidation trial is filed within 14 days like Hanmi, a generic for exclusicity can be jointly secured after the successful challenge. Elyson's Rx performance has been increasing rapidly since its launch in Korea in October 2017. According to UBIST, Elyson has grown more than three times in two years to ₩20.3 billion last year after it produced ₩6.3 billion in 2018, the first year of its release. In the first quarter of this year, prescriptions amounted to ₩5.8 billion, the highest quarterly prescription amount ever.
