- Oral Exon20 targeted Exkivity applies for reimb in Korea
- by Eo, Yun-Ho Dec 2, 2022 06:08am
- The EGFR Exon20 insertion mutation targeted oral therapy ‘Exkivity’ is attempting reimbursement listing in Korea. According to industry sources, Takeda Pharmaceuticals Korea recently applied for reimbursement listing of ‘Exkivity (mobocertinib), its treatment for non-small cell lung cancer (NSCLC) with EGFR exon 20 insertion mutations. Although the drug targets the same biomarker as Janssen Korea’s ‘Ryvrevant (amivantamab),’ Exkivity is different as an oral formulation. EGFR Exon20 insertion mutation is a new biomarker that is newly receiving attention in the field of NSCLC. Targeted anticancer therapies that are currently available for prescriptions include those that target the Exon19 deletion or Exon21 L858R substitution mutations that are commonly found in EGFR mutations, but an unmet need had existed for EGFR Exon20 insertion mutations. Therefore, the industry’s eyes are on whether Exkivity will succeed in reimbursement listing with Ryvrevant failing to pass deliberations by the Health Insurance Review and Assessment Service’s Cancer Disease Deliberation Committee. Meanwhile, Exkivity demonstrated its efficacy through a Phase I/II trial which enrolled 114 patients with EGFR Exon20 insertion-positive NSCLC who received prior platinum-based therapy. In the trial, patients who were treated with a 160 mg dose of Exkivity showed an objective response rate (ORR) of 28% as well as a median duration of response (DoR) of 17.5 months per independent review committee (IRC). In particular, the median time to response after Exkivity treatment was 1.9 months, demonstrating the rapid effect it shows from the beginning of treatment. The median progression-free survival (mPFS) was 7.3 months, and the median overall survival (mOS) 24.0 months. The safety profile was also manageable. The most common adverse reactions were diarrhea, rash, fatigue, etc, and were manageable through dosage adjustments.

- Leclaza P3T results unveiled... mPFS 20 months
- by Dec 2, 2022 06:07am
- The abstract data from a global Phase III trial on ‘Leclaza (lazertinib),’ the 31st homegrown novel drug developed by Yuhan Corp, has been released. In the trial, Leclaza improved progression-free survival (PFS) by 11 months compared to the existing treatment Iressa and met the primary endpoint. The study results of LASER301 above that assessed the safety and efficacy of Leclaza as first-line treatment in EGFR (epidermal growth factor receptor) mutant-positive NSCLC were released with other major study results on the 1st at the ESMO ASIA Congress 2022. LASER301 is a global Phase III trial that evaluated the efficacy and safety of Leclaza as first-line treatment in locally advanced or metastatic NSCLC patients with EGFR mutations. The trial enrolled 393 patients in 13 countries and compared Leclaza with the existing treatment, ‘gefitinib (brand name: Iressa).’ The primary efficacy endpoint was progression-free survival (PFS). The secondary endpoints were objective response rate (ORR), duration of response (DoR), disease control rate (DCR), and overall survival (OS). In terms of median PFS (mPFS), the primary efficacy endpoint, Leclaza’s mPFS was 20.6 months, a significant improvement over the 9.7 months in the control group. The drug also reduced the risk of disease progression and death by 55%. The PFS improvement was consistently observed in all predefined subgroups (Asians and non-Asians, Exon19del or L858R mutation, etc.). Leclaza’s DoR was 19.4 months, significantly longer than the 8.3 months in the control group. ORR was 76% in both treatment groups. The OS data has not matured yet (maturity 29%). At 18 months after administration, the lazertinib arm’s survival rate was 80%, higher than the 72% in the control group but did not reach statistical significance (p=0.116). Regarding its safety, lazertinib and Iressa showed a consistent safety profile with those that had been previously reported. The results of the LASER301 study will be presented at the ESMO ASIA Congress 2022 which will be held on the 3rd in Singapore. Leclaza is an NSCLC treatment that was approved as the 31st homegrown novel drug in January last year. It is a 3rd generation EGFR TKI that inhibits the proliferation and growth of lung cancer cells. It is currently approved as a second-line treatment for patients with locally advanced or metastatic NSCLC who developed resistance after being previously treated with 1st generation or 2nd generation EGFR-TKIs. Yuhan Corp conducted the global Phase III trial to expand the drug’s indication to first-line treatment in EGFR mutated lung cancer. The results greatly increased the possibility of the drug extending its indication to first-line in Korea. In Korea, Leclaza’s cumulative sales exceeded KRW 10 billion in only 1 year since its release with insurance reimbursement. If approved in the first line, its increase in sales is expected to accelerate further. Trials on its combined use with other drugs are also actively underway. Yuhan Corp had made a licensing deal with the global pharmaceutical company Janssen. Janssen has been developing the drug in combination with its own EGFR-MET bispecific antibody ‘Rybrevant (amivantamab).’

- Competition for chronic kidney disease following SGLT-2 I
- by Eo, Yun-Ho Dec 2, 2022 06:07am
- Competition for SGLT-2 inhibitors is expected to expand to the area of chronic kidney disease following heart failure. According to related industries, following AstraZeneca's Forxiga, Lilly and Beringer Ingelheim's Jardiance also succeeded in proving their effectiveness to secure chronic kidney disease indications. Forxiga is ahead in speed. After approval by the U.S. FDA in April, Forxiga immediately began the licensing process in major countries such as Korea and added chronic new disease indications in Korea and Europe in August. However, insurance benefits have not been applied so far. Forxiga's approval of chronic renal disease indication was based on phase 3 clinical DAPA-CKD study. Earlier this year, Forxiga was designated as a subject of the FDA-assigned Priority Review. According to the DAPA-CKD study, Forxiga reduced the relative risk of kidney failure compared to placebo, terminal kidney disease (ESKD), and death from cardiovascular or kidney by 39% in patients with stage 2-4 chronic kidney disease with increased UAE levels. ARR was 5.3% for 2.4 years, the median value of the study period. Jardiance recently announced the results of the EMPA-KIDNEY phase 3 at ASN's Kidney Week 2022. EMPA-KIDNEY was a study exclusively for a wide range of, large-scale SGLT-2 inhibitors, involving 6609 patients with various causes. Among them, many patients had cardiovascular, kidney, or metabolic-related comorbidities, and all kidney and cardiovascular results were evaluated according to the severity of various chronic kidney diseases. The previous SGLT-2 inhibitor study included the widest range of patients ever compared to a specific group with diabetes or high proteinuria among patients with chronic kidney disease. Looking at the study, Jardiance significantly reduced the risk of kidney disease progression or cardiovascular death by 28% compared to placebo. In addition, hospitalization due to all causes, one of the major complex secondary evaluation variables defined in advance, was significantly reduced by 14% compared to placebo. It was found that the results of hospitalization or cardiovascular death due to heart failure, a major secondary evaluation variable, or death reduction due to all causes were not statistically significant. Chronic kidney disease is a progressive disease, and it is investigated that up to 700 million patients around the world are distributed. Treatments that can be used in the patient group are limited, but it is necessary to enter new treatment options in that chronic kidney disease increases the incidence of cardiovascular events such as heart failure and affects early death.

- Balversa, the first targeted anticancer drug for bladder can
- by Dec 2, 2022 06:07am
- Targeted options targeting specific genetic mutations in bladder cancer have emerged for the first time. The Ministry of Food and Drug Safety announced on the 24th that it had approved Janssen's Balversa. It is an indication of metastatic urinary epithelial cancer (cystic cancer) with at least one type of chemotherapy treatment, or FGFR2 or 3 mutations within 12 months of adjuvant treatment before and after surgery, including platinum-based chemotherapy. Bladder cancer is representative cancer that had no targeted anticancer drugs. Balversa has become the first targeted anticancer drug for bladder cancer with a new mechanism called FGFR inhibition. FGFR is one of the bio-signals involved in cancer cell growth and is associated with several carcinomas. In particular, FGFR mutations are commonly observed in bladder cancer, and about 20 to 30% of patients are known to have mutations. The phase 2 BLC2001 study, which served as the basis for Balversa approval, targeted 99 patients with local progressive and metastatic urinary tract epithelial cancer with FGFR mutations. The ORR of 87 people who can be evaluated was 32.2% based on the IRRC evaluation. The disease control rate was 78% and the median response duration was 5.4 months. The progression-free survival (PFS) median and OS median were 5.5 months and 13.8 months, respectively. The most commonly reported adverse reactions of Grade 3 or higher include canker soreness, hand toenail dystrophy, hand toenail disorder, corneal inflammation, and hyperphosphatemia. Significant adverse reactions occurred in 41% of patients, of which eye disorders were reported by 10%. The adverse reactions that resulted in fatal results occurred in 1% of patients due to acute myocardial infarction. Based on the second phase, the Balversa permit was approved in April 2019, three years earlier than Korea in the U.S. To diagnose FGFR3 mutations, QuantiFERON's Therascreen FGFR Kit was also approved as a companion diagnostic device. ◆ A treatment for bladder cancer that has not existed for decades Bladder cancer is cancer that has been stagnant for decades. Unlike other cancers where several targeted anticancer drugs appeared, bladder cancer has been the main treatment until recently. The development of new drugs was not easy because of the high effectiveness of early chemotherapy. However, in metastatic bladder cancer, chemotherapy reacts in the early stages, and most of them die within two years due to resistance. Recently, immuno-cancer drugs have emerged, causing changes in the treatment of bladder cancer. There are four immuno-cancer drugs, including Keytruda, Opdivo, Tecentriq, and Bavencio, and there is a slight difference in specific indications. Keytruda and Tecentriq can be used as primary treatments. However, it can be used only when PD-L1 expression is positive and Cisplatin-based chemotherapy is impossible. Bavencio can be used as a maintenance therapy without the disease progressing after using chemotherapy in the first round. Opdivo is used as a secondary treatment when the disease progresses after chemotherapy. Keytruda and Tecentriq can also be used in the second round. Immuno-cancer drugs have a high response rate of around 20%, but they have fewer side effects than chemotherapy and have the advantage of maintaining treatment responses for a long time. With Balversa's permission, patients with FGFR mutations can consider targeted anticancer drugs in secondary or higher treatment, which is expected to help improve their prognosis.

- Ajovy will it be possible to register this year?
- by Eo, Yun-Ho Dec 1, 2022 05:46am
- Attention is focusing on whether the second CGRP target migraine drug Ajovy will be able to apply for insurance benefits within this year. According to related industries, Teva Handok is conducting last-minute coordination in drug price negotiations between the NHIS and the Calcitonin gene-related peptide (CGRP) target migraine treatment Ajovy. Considering that the benefit of Emgality in September, a competitive drug and the first entry item, has been applied, the negotiations have been delayed more than expected. Currently, there is no big disagreement with the calculation of drug prices itself, but factors such as the expected amount of claims are known to be an obstacle. Considering the negotiation date, if it goes according to the procedure, it is possible to register within this year, so we have to watch Ajovy's progress. If Ajovy succeeds in registering, competition between the two drugs is expected to begin in earnest. Emgality and Ajovy are the same drugs, and they are selected according to the characteristics of severe migraine patients. Emgality is a method of administering 240 mg (two consecutive subcutaneous injections each of 120 mg) once at a loading dose, and then subcutaneous injections of 120 mg once a month. Ajovy is used by subcutaneous injection of 225 mg once a month or 675 mg (three consecutive times of 225 mg) once every three months. Ajovy proved its effectiveness through a 12-week HALO EM/CM clinical trial in 2,000 patients with EM and CM. In a HALOEM study conducted to verify the efficacy and safety of Ajovy compared to the placebo group, Ajovy was evaluated to meet the primary evaluation variable by significantly reducing the number of monthly migraine occurrences in both monthly and quarterly administration groups. The proportion of patients whose average monthly migraine days decreased by more than 50% was also higher at 47.7% in the Ajovy monthly administration group and 44.4% in the quarterly administration group compared to 27.9% in the placebo group. In the HALOCM study, the average number of monthly headache reduction days in the Ajovy administration group was 4.6±0.3 days, and the quarterly administration group was 4.3±03 days, showing a significant decrease compared to 2.5±0.3 days in the placebo group.
