项目摘要
The opioid crisis has emphasized the need for better non-addictive therapeutics for pain management. The
chemotherapy-induced peripheral neuropathy (CIPN) imposed on approximately half of patients receiving
oxaliplatin treatment for cancer is a significant additional burden. While sophisticated molecular tools are now
being introduced to attack cancer and despite severe adverse effects, oxaliplatin chemotherapy remains in wide
usage as a primary treatment response at many sites. Its high prevalence of neurotoxicity often limits
chemotherapeutic dosing efficacy and maximum therapeutic effect. Patients can experience disabling cold and
mechanical hypersensitivity that persist for years after treatment. The toxic effects can cause premature
termination of treatment, impacting quality of life and survivability. CIPN can lead to permanent symptoms and
disability in up to 40% of cancer survivors subsequently, thus the societal loss in dollars is inestimable. There
are no drugs preventing development of CIPN, and CIPN has a poor therapeutic response to analgesics. Our
current collaborative effort focuses on optimizing a small molecule single chain Fragment variable antibody
(scFv) therapy that reverses chronic neuropathic pain. Smaller engineered scFvs (25-28 kDa) feature similar
binding activity but stronger tissue and brain penetrability. These small molecules are considered suitable drug
candidates for pain control since they satisfy key parameters such as (1) high affinity for the therapeutic target,
(2) high thermostability, (3) lack of aggregation, and (4) availability from high expression cell lines. Commercial
viability is dependent on humanization and affinity purification of the current patent pending small brain penetrant
scFv therapy effective in murine models. The objective of this proposal is to humanize the current small scFv
antibody and while maintaining more than 50% effectiveness in the murine CIPN pain model. The methodology
used will be to ascertain the minimum requirements for humanization, affinity maturation, and then to bench test
the antibody for effectiveness in the CIPN model vivo and in in vitro models including human-like neurons,
expression systems, and primary sensory neurons from CIPN mice to validate feasibility for continuing with
human clinical trials. Finally, we will seek independent commercial confirmation to demonstrate safety with
PK/PD, distribution, and toxicology validation studies. The ultimate objective of this project is realization of an
effective and commercially viable non-opioid treatment for chemotherapy induced neuropathic pain (CINP). The
single chain Fragment variable (scFv) antibody therapy designed would prevent CINP and/or mitigate long
standing, disabling CINP.

没有预防CIPN发展的药物,而且CIPN对止痛药的治疗反应很差。我们的
目前的合作重点是优化一种小分子单链片段可变抗体
(ScFv)逆转慢性神经病理性疼痛的疗法。较小的工程单链抗体(25-28 kDa)具有类似的特征
结合活性,但组织和脑的穿透性更强。这些小分子被认为是合适的药物
因为它们满足关键参数,例如(1)对治疗靶点的高亲和力,

人体临床试验。最后,我们将寻求独立的商业确认,以证明安全与
PK/PD、分布和毒理学验证研究。该项目的最终目标是实现一个
有效且商业上可行的非阿片类药物治疗化疗引起的神经病理性疼痛(CINP)。这个
单链片段可变型(ScFv)抗体疗法可预防CINP和/或缓解Long
