Abstract
Description
본 발명은 면역세포치료제 조성물에 관한 것이다.The present invention relates to an immune cell therapy composition.
빠르게 증식하는 종양세포의 특성을 이용하여 분열하는 세포를 공격하는 화학항암제와 종양 세포의 특정 분자나 세포신호전달체계를 표적하는 표적항암제에 대한 개발이 과거에 다수 수행되었으나, 최근에는 면역학적 방법을 이용하여 종양을 치료하는 면역항암제로 그 항암제 개발 과정이 변화되고 있다. 면역항암제는 종양 항원을 표적하는 항체치료제(Rituximab 등), 면역세포를 다시 활성화시키는 면역관문억제제(Immune checkpoint inhibitor 등) 및 면역세포를 직접 투여하는 면역세포치료제(Immune cell theraphy) 등으로 구분될 수 있다(Oiseth et al, 2017).Using the characteristics of rapidly proliferating tumor cells, the development of chemical anticancer agents that attack dividing cells and targeted anticancer agents that target specific molecules or cell signaling systems of tumor cells have been conducted in the past, but recently, immunological methods have been developed. The process of developing anti-cancer drugs is changing as an immuno-oncology drug that treats tumors using chemotherapy. Immune anticancer drugs can be divided into antibody therapeutics that target tumor antigens (Rituximab, etc.), immune checkpoint inhibitors that reactivate immune cells (Immune checkpoint inhibitors, etc.), and immune cell therapies that directly administer immune cells (Immune cell therapy). There is (Oiseth et al, 2017).
상기 면역세포치료제의 경우, 1980년대 중반 NIH(National Institutes of Health)를 중심으로 체외 배양되어 활성화된 자가 T 세포를 이용한 악성 흑색종 환자의 치료와 관련된 임상연구가 시도되면서 많은 연구가 수행되어 왔다. 그러나, 항원 특이성이 부여되지 않은 T 세포는 악성 종양을 제거하는데 충분한 효과가 발휘되지 못하였다. 이와 관련하여, 2010년 덴드레온(Dendreon)사에서 FDA로부터 허가받은 수지상세포치료제인 프로벤지(Provenge)가 최초 의약품에 해당한다. 그러나, 이와 같은 치료제는 가격 대비 낮은 유효성 등의 이유로 시장에서 큰 호응을 받지 못하였다.In the case of the immune cell therapy, many studies have been conducted in the mid-1980s as clinical studies related to the treatment of malignant melanoma patients using in vitro cultured and activated autologous T cells centered on the National Institutes of Health (NIH) were attempted. However, T cells to which antigen specificity is not conferred did not exhibit sufficient effect to remove malignant tumors. In this regard, Provenge, a dendritic cell therapy approved by the FDA by Dendreon in 2010, is the first drug. However, such therapeutic agents have not been well-received in the market due to low efficacy compared to the price.
이와 같은 한계점에 따라, T 세포에 항원 특이성을 부여하기 위한 다양한 공정이 시도되어 왔다. 특히, 항체인식부위(scFv)와 T 세포의 세포내 활성화 도메인을 결합시킨 키메릭항원수용체(Chimeric antigen receptor; CAR)를 이용한 방법이 매우 효과적으로 T 세포에 항원 특이성을 부여할 수 있는 것으로 각광받고 있다. 이와 관련하여, 노바티스(Norvatis)사에 의해 개발된 CD19-CAR-T인 Kymriah(제품명)는 2017년 8월 미국 FDA에 의해 허가되었으며, 이러한 흐름에 맞추어 면역세포치료제의 본격적인 상업화가 시작되었다.According to these limitations, various processes for conferring antigen specificity to T cells have been tried. In particular, a method using a chimeric antigen receptor (CAR) that combines an antibody recognition site (scFv) with an intracellular activation domain of T cells is in the spotlight as being able to confer antigen specificity to T cells very effectively. . In this regard, Kymriah (product name), a CD19-CAR-T developed by Novartis, was approved by the US FDA in August 2017, and in line with this trend, full-scale commercialization of immune cell therapy began.
그러나, 상기 CAR-T 세포의 경우 우선적으로 환자 자신에게서 T 세포를 채취한 뒤, 채취된 T 세포를 이용하여 복잡한 유전자 조작 공정을 거쳐야 하기 때문에 비용이 과도하다는 단점이 존재한다. 뿐만 아니라, 표적 세포와 접촉하는 경우 T 세포는 빠르게 분열하므로 사이토카인폭풍(Cytokine release syndrome; CRS) 및 중추 신경계의 부종과 같은 심각한 부작용이 보고되고 있으며, T 세포는 메모리 T 세포에 의해 치료받은 환자에게 장기간 존재하여 언제든 동일한 부작용이 발생될 수 있다. 나아가, 이와 같은 CAR-T 세포는 면역억제적인 종양미세환경(Tumor microenvironment)과 암세포의 이질성(Heterogeneity) 뿐만 아니라, 혈액암에 비해 상대적으로 CAR-T 세포의 침투가 어렵기 때문에 고형암의 치료에 적용하기 위해서는 한계점이 있다.However, in the case of the CAR-T cells, there is a disadvantage in that the cost is excessive because T cells are first collected from the patient themselves, and then a complex genetic manipulation process is performed using the collected T cells. In addition, since T cells divide rapidly when in contact with target cells, serious side effects such as cytokine release syndrome (CRS) and central nervous system edema have been reported, and T cells are treated by memory T cells in patients The same side effects can occur at any time due to its long-term presence in Furthermore, such CAR-T cells are applied to the treatment of solid cancers because of their immunosuppressive tumor microenvironment and heterogeneity of cancer cells, as well as relatively difficult penetration of CAR-T cells compared to blood cancers. There are limits to this.
이러한 문제점을 해결하기 위하여 최근 자연살해세포(Natural killer cell; NK cell)를 이용한 항암면역세포치료제의 개발이 활발하게 진행되고 있다. 상기 자연살해세포는 인간의 면역반응에서 종양 세포나 바이러스가 감염된 세포와 같은 비 정상적인 세포를 즉각적으로 인식하여 제거할 수 있는 기능을 갖는 세포에 해당한다. 이러한 자연살해세포는 T 세포와 비교하여, 메모리 기능과 자가복제 기능이 상대적으로 약하기 때문에, 사이토카인폭풍과 같은 부작용이 상대적으로 적을 수 있다는 장점이 존재한다.In order to solve this problem, the development of anticancer immune cell therapy using natural killer cells (NK cells) is being actively conducted. The natural killer cells correspond to cells having a function of immediately recognizing and removing abnormal cells such as tumor cells or virus-infected cells in a human immune response. Since these natural killer cells have relatively weak memory function and self-replication function compared to T cells, there is an advantage that side effects such as cytokine storm may be relatively small.

본 발명의 상기 "프라이머"는 표적 유전자 서열을 인지하는 단편으로서, 정방향 및 역방향의 프라이머 쌍을 포함하나, 바람직하게는, 특이성 및 민감성을 가지는 분석 결과를 제공하는 프라이머 쌍이다. 프라이머의 핵산 서열이 시료 내 존재하는 비-표적 서열과 불일치하는 서열이어서, 상보적인 프라이머 결합 부위를 함유하는 표적 유전자 서열만 증폭하고 비특이적 증폭을 유발하지 않는 프라이머일 때, 높은 특이성이 부여될 수 있다.The "primer" of the present invention is a fragment recognizing a target gene sequence, and includes a pair of forward and reverse primers, but preferably, a primer pair that provides analysis results with specificity and sensitivity. When the nucleic acid sequence of the primer is a sequence that is inconsistent with a non-target sequence present in the sample, and thus amplifies only the target gene sequence containing the complementary primer binding site and does not cause non-specific amplification, high specificity can be conferred. .
본 발명의 상기 "프로브"란 시료 내의 검출하고자 하는 표적 물질과 상보적으로 결합할 수 있는 물질을 의미하며, 상기 결합을 통하여 특이적으로 시료 내의 표적 물질의 존재를 확인할 수 있는 물질을 의미한다. 프로브의 종류는 당업계에서 통상적으로 사용되는 물질로서 제한은 없으나, 바람직하게는 PNA(peptide nucleic acid), LNA(locked nucleic acid), 펩타이드, 폴리펩타이드, 단백질, RNA 또는 DNA일 수 있으며, 가장 바람직하게는 PNA이다. 보다 구체적으로, 상기 프로브는 바이오 물질로서 생물에서 유래되거나 이와 유사한 것 또는 생체 외에서 제조된 것을 포함하는 것으로, 예를 들어, 효소, 단백질, 항체, 미생물, 동식물 세포 및 기관, 신경세포, DNA, 및 RNA일 수 있으며, DNA는 cDNA, 게놈 DNA, 올리고뉴클레오타이드를 포함하며, RNA는 게놈 RNA, mRNA, 올리고뉴클레오타이드를 포함한다.The "probe" of the present invention means a substance capable of complementary binding to a target substance to be detected in a sample, and means a substance capable of specifically confirming the presence of a target substance in the sample through the binding.

LNA가 DNA 또는 RNA 올리고뉴클레오티드에 포함되면, LNA는 보다 빠르게 상보적 뉴클레오티드 사슬과 쌍을 이루어 이중 나선의 안정성을 높일 수 있다.The "LNA (Locked nucleic acids)" of the present invention means a nucleic acid analog comprising a 2'-O, 4'-C methylene bridge [J Weiler, J Hunziker and J Hall Gene Therapy (2006) 13, 496.502) ]. LNA nucleosides contain common nucleic acid bases in DNA and RNA, and can form base pairs according to Watson-Crick base pairing rules. However, due to the 'locking' of the molecule due to the methylene bridge, the LNA does not form an ideal shape at the Watson-Crick bond. When LNA is incorporated into DNA or RNA oligonucleotides, LNA can pair with complementary nucleotide chains more rapidly, increasing the stability of the double helix.
