Business Overview and History
Quoin Pharmaceuticals Ltd. is a late clinical-stage specialty pharmaceutical company dedicated to developing and commercializing therapies that address rare and orphan diseases. With a focus on unmet medical needs, the company is at the forefront of advancing innovative treatments that have the potential to transform the lives of patients and their families.
Quoin Pharmaceuticals Ltd. has a rich history dating back to 1986 when it was originally founded under a different name. The company has undergone several name changes throughout its existence. In 2018, a significant development occurred with the incorporation of Quoin Pharmaceuticals, Inc. as a wholly-owned subsidiary in Delaware.
A pivotal moment in the company's history came on October 28, 2021, when Cellect Biotechnology Ltd. completed a business combination with Quoin Pharmaceuticals, Inc. This merger resulted in Quoin Pharmaceuticals, Inc. becoming a wholly-owned subsidiary of Cellect. Immediately following the completion of this transaction, Cellect changed its name to Quoin Pharmaceuticals Ltd., marking the beginning of a new era for the company.
Since its inception, Quoin has maintained a clear focus on the development and commercialization of therapeutic products targeting rare and orphan diseases. The company's strategy revolves around leveraging its proprietary owned and in-licensed drug delivery technologies to address rare genetic diseases. This approach has led to the development of Quoin's lead product, QRX003, which is currently under clinical investigation as a potential treatment for Netherton Syndrome (NS), a rare hereditary genetic disease.
It's important to note that Quoin, as a clinical-stage company, has not yet commercialized any products or generated revenue. The company has primarily relied on debt and equity financings to fund its operations, facing challenges typical of development-stage biopharmaceutical companies. These challenges include unanticipated or higher than expected clinical trial costs and the difficulty in accurately estimating the impact of such occurrences on the company's cash position, liquidity, and additional financing requirements.
In 2022, Quoin encountered a regulatory hurdle when it received a deficiency letter from Nasdaq. The notification informed the company that its American Depositary Shares (ADSs) did not maintain the minimum closing bid price required for continued listing. In response to this challenge, Quoin was granted an extension to regain compliance with the minimum bid price requirement. This situation highlighted the potential risk of delisting from Nasdaq, which could adversely affect investors' ability to trade Quoin's securities and impact the value of its ADSs.
Under the leadership of Dr. Myers as CEO and Denise Carter as COO, Quoin has made significant strides in advancing its clinical programs. The company currently has three ongoing clinical studies for QRX003 in NS patients, including a groundbreaking "whole body" study being conducted at Northwestern University. Quoin has also expanded its global reach, establishing clinical sites in the Middle East, United Kingdom, and various European countries to further evaluate QRX003 in both adult and pediatric NS populations.
In addition to its focus on NS, Quoin has diversified its pipeline by entering into research agreements with leading institutions, such as the Queensland University of Technology (QUT) and University College Cork (UCC). These collaborations have provided the company with options to license novel product candidates targeting other rare diseases, including scleroderma, microcystic lymphatic malformations, and angiofibromas.
Financial Overview
Quoin Pharmaceuticals is a clinical-stage company, and as such, it has not yet generated any revenue from product sales. The company has historically funded its operations through equity and debt financings, raising capital to support its research and development efforts.
As of December 31, 2024, Quoin reported cash and investments totaling $14.06 million, providing the company with the necessary resources to continue advancing its clinical programs. The company's net loss for the year ended December 31, 2024, was $8.96 million, with research and development expenses of $3.60 million and general and administrative expenses of $5.93 million.
For the most recent quarter (Q3 2024), Quoin reported no revenue and a net loss of $2.35 million. The company's accumulated deficit as of December 31, 2024, was approximately $55.2 million, reflecting the substantial investments made in research and development since its inception.
Liquidity
Quoin's financial position is characterized by a current ratio of 3.57 and a quick ratio of 3.57, indicating a strong liquidity profile. The company's balance sheet is free of long-term debt, further strengthening its financial flexibility. As of December 31, 2024, Quoin had cash balances of $3.6 million and investments of $10.4 million.
The company believes it has sufficient cash and liquidity to execute its business plan for at least the next twelve months. However, Quoin acknowledges that it will require additional financing to complete the research and development of its therapeutic targets and meet other operating requirements until it achieves commercial profitability, if ever.
Product Pipeline and Clinical Developments
Netherton Syndrome (NS) Quoin's lead product candidate, QRX003, is being developed as a potential treatment for Netherton Syndrome, a rare and debilitating genetic disorder. The company currently has three ongoing clinical studies for QRX003 in NS patients under an open Investigational New Drug (IND) application with the FDA.
In December 2024, Quoin announced highly positive interim data from its ongoing open-label NS study, where the first subject dosed twice-daily with QRX003 demonstrated clear improvements across all measured clinical endpoints, including the Investigator's Global Assessment (IGA), Worst Itch Numeric Rating Scale (WINRS), and patient satisfaction scores. Notably, the subject experienced a complete reversal of the positive clinical benefits within four weeks of discontinuing QRX003 treatment, underscoring the product's mechanism of action as a competitive broad-spectrum serine protease inhibitor.
Furthermore, in the company's ongoing Investigator Pediatric NS study, Quoin reported that a significant improvement in skin appearance was observed in the study subject after just 12 days of QRX003 treatment, with the IGA assessment improving from "severe" at baseline to "mild-moderate." Based on these positive results, the subject was transitioned to having QRX003 applied to their entire body surface area.
Quoin has also received FDA clearance to initiate a new "whole body" NS study, which will be conducted by Dr. Amy Paller at Northwestern University. This study will evaluate the safety and efficacy of QRX003 when applied twice daily to greater than 80% of a patient's body surface area over a 12-week period, providing valuable data to support the potential real-world use of the product.
Expansion into Additional Rare Diseases Beyond its focus on Netherton Syndrome, Quoin has leveraged its research collaborations to expand its pipeline into other rare and orphan disease indications. In November 2021, the company entered into research agreements with Queensland University of Technology (QUT) to develop potential treatments for Netherton Syndrome (QRX007) and scleroderma (QRX008).
Additionally, in June 2024, Quoin signed a research agreement with the University College Cork (UCC) to develop novel topical formulations of rapamycin (sirolimus) as potential treatments for a variety of rare diseases, including microcystic lymphatic malformations, venous malformations, and angiofibromas. The company plans to submit Investigational New Drug (IND) applications and initiate clinical testing for these new product candidates in the coming year.
Quoin is also developing QRX004 as a potential treatment for Recessive Dystrophic Epidermolysis Bullosa (RDEB), further expanding its pipeline of rare disease therapeutics.
Regulatory and Commercialization Milestones Quoin's commitment to addressing unmet medical needs in rare diseases is underscored by its regulatory strategy. The company is actively pursuing Orphan Drug and Rare Pediatric Disease designations for QRX003 in the United States and European Union, which could provide significant clinical and commercial advantages.
Additionally, Quoin is expanding its global reach by establishing clinical sites in the Middle East, United Kingdom, and various European countries to evaluate QRX003 in both adult and pediatric NS populations. The company has opened five clinical sites in the United States and intends to open a sixth site at Northwestern University. Quoin is also expanding its QRX003 trials internationally into Spain and Germany. A pediatric NS patient is being treated at the Children's Hospital in Dublin, Ireland, with plans to expand this study to include more children with NS in Spain, the UK, and potentially other countries.
Furthermore, Quoin is developing QRX003 as a potential treatment for Peeling Skin Syndrome, with the first subject being treated in New Zealand. This expansion into additional indications demonstrates the company's commitment to maximizing the potential of its lead product candidate.
As Quoin progresses towards potential regulatory approvals, the company is also laying the groundwork for commercial success. The company has already established distribution partnerships in several key markets, including Canada, Australia/New Zealand, the Middle East, China, Hong Kong, Taiwan, Latin America, Central and Eastern Europe, and Singapore, positioning it to effectively launch QRX003 in these regions, if approved.
Risks and Challenges
Despite Quoin's promising progress, the company faces several risks and challenges that are common to the biopharmaceutical industry. The successful development and commercialization of its product candidates, including QRX003, are subject to extensive regulatory oversight, clinical trial outcomes, and potential manufacturing or supply chain disruptions.
Additionally, as a clinical-stage company, Quoin is dependent on its ability to raise additional capital to fund its ongoing research and development activities. Failure to secure sufficient funding could delay or halt the company's programs, adversely impacting its long-term growth and potential.
Another key risk is the competitive landscape in the rare disease space. While Quoin's pipeline targets unmet needs, the company may face competition from other pharmaceutical and biotechnology companies pursuing similar indications. Effective differentiation and successful execution of the company's clinical and regulatory strategies will be crucial to its long-term success.
