ファストトラック指定制度( https://c212.net/c/link/?t=0&l=ja&o=2560933-1&h=385204323&u=https%3A%2F%2Fwww.fda.gov%2Fpatients%2Ffast-track-breakthrough-therapy-accelerated-approval-priority-review%2Ffast-track&a=%E3%83%95%E3%82%A1%E3%82%B9%E3%83%88%E3%83%88%E3%83%A9%E3%83%83%E3%82%AF%E6%8C%87%E5%AE%9A%E5%88%B6%E5%BA%A6 )は、重篤または生命を脅かす恐れのある疾患およびアンメットメディカルニーズの高い疾患に対して、治療効果が期待される新薬をFDAが優先的に審査する制度であり、この指定を取得することで、FDAと協議機会をより多く与えられ、新薬の開発ならびに審査を促進することができる。

指定取得に関し、DiscGenicsのCEO兼会長であるフラグ・フラナガン氏は「弊社がこれまでに収集してきた有力な前臨床( https://c212.net/c/link/?t=0&l=ja&o=2560933-1&h=2617384580&u=https%3A%2F%2Fwww.thespinejournalonline.com%2Farticle%2FS1529-9430(19)30935-0%2Ffulltext&a=%E5%89%8D%E8%87%A8%E5%BA%8A )(1)および安全性( https://c212.net/c/link/?t=0&l=ja&o=2560933-1&h=3537874031&u=https%3A%2F%2Fwww.discgenics.com%2Fnews-posts%2F2019%2F1%2F7%2Fdiscgenics-announces-that-idct-has-passed-the-initial-safety-review-of-its-first-in-human-clinical-trial-for-degenerative-disc-disease&a=%E5%AE%89%E5%85%A8%E6%80%A7 )データに裏付けられた朗報であり、治療オプションに欠ける腰痛をFDAが重篤な疾患として認識していることを示唆している」とコメントした。また、「弊社はこれまで、既存規制の枠組みの中で可及的速やかにIDCTを患者様に届ける努力をしてきており、この指定取得によって当該努力に対し、以前にも増してコミットして行きたい思いである」ともコメントしている。

IDCTに含まれる他家・相同利用のディスコジェニック細胞( https://c212.net/c/link/?t=0&l=ja&o=2560933-1&h=1118350335&u=https%3A%2F%2Fwww.discgenics.com%2Fdiscogenics-cells-ja&a=%E3%83%87%E3%82%A3%E3%82%B9%E3%82%B3%E3%82%B8%E3%82%A7%E3%83%8B%E3%83%83%E3%82%AF%E7%B4%B0%E8%83%9E )は、椎間板組織由来の前駆細胞であり、注入剤であるため、低侵襲な方法で軽度から中程度の変形性椎間板症の組織再生を促す可能性を秘めている。また、他家の細胞治療製剤であるIDCTは、アメリカ公衆衛生法(PHSA:Public Health Service Act)セクション351に基づきFDA生物製剤評価研究センター(CBER:Center for Biologics Evaluation and Research)の管轄下にある。このためDiscGenicsは、厳重な新薬開発プロセスを設けており、治療効果を臨床評価しつつ、cGMP製造によって細胞治療開発に必要なロット間の品質および安全性を担保している。

現在DiscGenicsは、日本( https://c212.net/c/link/?t=0&l=ja&o=2560933-1&h=1941418938&u=https%3A%2F%2Fclinicaltrials.gov%2Fct2%2Fshow%2FNCT03955315&a=%E6%97%A5%E6%9C%AC )および米国( https://c212.net/c/link/?t=0&l=ja&o=2560933-1&h=1735502536&u=https%3A%2F%2Fclinicaltrials.gov%2Fct2%2Fshow%2FNCT03347708&a=%E7%B1%B3%E5%9B%BD )においてIDCTを評価する個別の多施設共同・コントロール下・無作為化・二重盲検試験を実施している。米国においては、新薬臨床試験開始届(IND:Investigational New Drug application)を提出し臨床試験を開始しており、上市前には生物学的製剤承認申請書(BLA:Biologic License Application)を提出する予定である。また、日本における臨床試験( https://c212.net/c/link/?t=0&l=ja&o=2560933-1&h=3090651057&u=https%3A%2F%2Fwww.discgenics.com%2Fnews-posts%2F2019%2F8%2F7%2Fdiscgenics-announces-first-patients-treated-in-japanese-clinical-trial-of-cell-therapy-for-degenerative-disc-disease&a=%E8%87%A8%E5%BA%8A%E8%A9%A6%E9%A8%93 )は、医薬品医療機器総合機構に提出した治験計画届出に基づき実施している。両試験の主要評価項目は安全性であり、有効性の主要評価項目は痛みの軽減度合いである。また、副次評価項目として障害の改善および画像診断項目の改善を設定している。なお、米国の臨床試験では既に低用量コホートにおける安全性が確認されており( https://c212.net/c/link/?t=0&l=ja&o=2560933-1&h=3380783469&u=https%3A%2F%2Fwww.discgenics.com%2Fnews-posts%2F2019%2F1%2F7%2Fdiscgenics-announces-that-idct-has-passed-the-initial-safety-review-of-its-first-in-human-clinical-trial-for-degenerative-disc-disease&a=%E4%BD%8E%E7%94%A8%E9%87%8F%E3%82%B3%E3%83%9B%E3%83%BC%E3%83%88%E3%81%AB%E3%81%8A%E3%81%91%E3%82%8B%E5%AE%89%E5%85%A8%E6%80%A7%E3%81%8C%E7%A2%BA%E8%AA%8D%E3%81%95%E3%82%8C%E3%81%A6%E3%81%8A%E3%82%8A )、日米両試験において現在も被験者の募集を行なっている。

慢性腰痛および変形性椎間板症について

慢性的な腰痛は、世界で最も多い障害の要因であり(2)、米国においては、がんの痛みに使用される分を除けば、最もオピオイド鎮痛剤が処方される重篤な疾患である(3)。また、米国では成人の12%〜30%が患う疾患と言われており(4)、1年間で同国の医療制度にかかる負担として1千億ドル超と言われている(2)。このため、医療経済はもちろんのこと、患者様一人一人にも重い負担がかかる疾患である。慢性腰痛に悩む患者の約40%は、椎間板の変性を伴う慢性的かつ進行性の疾患である変形性椎間板症を患うとされている(5)(6)(7)。

DiscGenicsについて

DiscGenicsは、脊椎関連変性疾患を患う患者の疼痛緩和および機能改善をする再生医療等製品の開発に注力する臨床開発段階にある未上場バイオベンチャー企業である。世界で唯一椎間板疾患を治療するための椎間板由来他家細胞治療製剤を開発した企業として、腰痛に悩む数多くの患者を治療するユニークなポジションを有している。同社最初の開発品目であるIDCTに含まれる他家・相同利用のディスコジェニック細胞は、椎間板組織由来の前駆細胞であり、手術を伴わない注入剤として投与されるため、低侵襲な方法で軽度から中程度の変形性椎間板症の組織再生を促す可能性を秘めている。

Fast Track (

https://c212.net/c/link/?t=0&l=en&o=2560933-1&h=1344265282&u=https%3A%2F%2Fwww.fda.gov%2Fpatients%2Ffast-track-breakthrough-therapy-accelerated-approval-priority-review%2Ffast-track&a=Fast+Track

) is a special regulatory designation that companies can apply for once they

have sufficient preclinical and clinical evidence that a product may be able to

treat an unmet medical need for a serious medical condition. With this

designation, Sponsors may benefit from early and frequent communication with

FDA, eligibility for Accelerated Approval and Priority Review programs, as well

as a Rolling Review application process for marketing licensure.

"We are thrilled to receive Fast Track designation for IDCT as it recognizes

the extremely compelling preclinical (

https://c212.net/c/link/?t=0&l=en&o=2560933-1&h=3096744115&u=https%3A%2F%2Fwww.thespinejournalonline.com%2Farticle%2FS1529-9430(19)30935-0%2Ffulltext&a=preclinical

) (1) and safety data (

https://c212.net/c/link/?t=0&l=en&o=2560933-1&h=791438136&u=https%3A%2F%2Fwww.discgenics.com%2Fnews-posts%2F2019%2F1%2F7%2Fdiscgenics-announces-that-idct-has-passed-the-initial-safety-review-of-its-first-in-human-clinical-trial-for-degenerative-disc-disease&a=safety+data

) we have generated for IDCT through our robust research and development and

clinical programs, and underscores FDA's acknowledgement of low back pain as a

serious medical condition with a profound lack of treatment options," said

Flagg Flanagan, Chairman and CEO of DiscGenics, Inc. "This Fast Track

designation reinforces our commitment to working with regulators to identify

ways to accelerate development and expedite approval of the therapy within

existing regulatory frameworks to make IDCT available to patients as quickly as

possible."

IDCT is a homologous, allogeneic, injectable cell therapy that utilizes

biomedically engineered progenitor cells, known as Discogenic Cells (

https://c212.net/c/link/?t=0&l=en&o=2560933-1&h=2823742337&u=https%3A%2F%2Fwww.discgenics.com%2Fresearch-and-development%2F&a=Discogenic+Cells

), that have been derived from intervertebral disc tissue to offer a

non-invasive, potentially regenerative solution for the treatment of mild to

moderate DDD. As a manufactured allogeneic cell therapy, IDCT is regulated by

FDA's Center for Biologics Evaluation and Research (CBER) under Section 351 of

the Public Health Service Act (PHSA). As a result, DiscGenics is adhering to

the rigors of a regulated drug pathway that require the Company to not only

prove that the product has a therapeutic effect through clinical evaluation,

but also that it meets critical safety standards and is produced consistently

from lot to lot through adherence to current good manufacturing practice (cGMP)

standards for a cell therapy.

DiscGenics is conducting two parallel prospective, randomized, double-blinded,

controlled, multicenter clinical trials of IDCT in the U.S. (

https://c212.net/c/link/?t=0&l=en&o=2560933-1&h=737266639&u=https%3A%2F%2Fclinicaltrials.gov%2Fct2%2Fshow%2FNCT03347708&a=U.S.

) and Japan (

https://c212.net/c/link/?t=0&l=en&o=2560933-1&h=1164363533&u=https%3A%2F%2Fclinicaltrials.gov%2Fct2%2Fshow%2FNCT03955315&a=Japan

). IDCT is being evaluated in the U.S. under an investigational new drug (IND)

allowance by the FDA and will be regulated as a drug-biologic through a

biologics license application (BLA). In Japan, the trial (

https://c212.net/c/link/?t=0&l=en&o=2560933-1&h=3128444002&u=https%3A%2F%2Fwww.discgenics.com%2Fnews-posts%2F2019%2F8%2F7%2Fdiscgenics-announces-first-patients-treated-in-japanese-clinical-trial-of-cell-therapy-for-degenerative-disc-disease&a=trial

) is supported by a Clinical Trial Notification (CTN) approved by the Japanese

Pharmaceuticals and Medical Devices Agency (PMDA). Primary outcome measures

include safety and reduction in pain. Secondary outcome measures include

reduction in disability and radiographic improvement. Importantly, the U.S.

study has shown safety in the first cohort of patients (

https://c212.net/c/link/?t=0&l=en&o=2560933-1&h=2622105774&u=https%3A%2F%2Fwww.discgenics.com%2Fnews-posts%2F2019%2F1%2F7%2Fdiscgenics-announces-that-idct-has-passed-the-initial-safety-review-of-its-first-in-human-clinical-trial-for-degenerative-disc-disease&a=shown+safety+in+the+first+cohort+of+patients

). For both studies, enrollment is ongoing.

About Chronic Low Back Pain and Degenerative Disc Disease

Chronic low back pain is a serious medical condition that represents a leading

cause of disability worldwide (2) and is the most common non-cancer reason for

opioid prescription in the U.S. (3). It affects 12-30% of U.S. adults at a

given time (4) and is estimated to cost the U.S. healthcare system over $100

billion each year (2), creating a significant burden on the economy and

individual patients dealing with the condition. In nearly 40% of patients, low

back pain is caused by DDD (5-7), a chronic and progressive condition where the

intervertebral disc breaks down and causes pain.

About DiscGenics

DiscGenics is a privately held, clinical stage biotechnology company focused on

developing regenerative cell-based therapies that alleviate pain and restore

function in patients with degenerative diseases of the spine. As the only

company in the world to develop an allogeneic cell therapy derived from

intervertebral disc cells to treat diseases of the disc, DiscGenics believes it

has a unique opportunity to harness the restorative potential of the human body

to heal millions of patients suffering from the debilitating effects of back

pain. DiscGenics' first product candidate, IDCT, is a homologous, allogeneic,

injectable cell therapy that utilizes biomedically engineered progenitor cells

derived from intervertebral disc tissue, known as Discogenic Cells, to offer a

non-surgical, potentially regenerative solution for the treatment of patients

with mild to moderate degenerative disc disease. For more, visit
