History and Development of the Company
We
are a development stage biotech company specializing in the development of innovative medical device hydrogels delivered in the form
of nasal sprays, which form a thin hydrogel-based shield containment barrier in the nasal cavity that can provide a barrier against viruses
and allergens from contacting the nasal epithelial tissue. Our C&C, hydrogel technology, comprised of a mixture of naturally occurring
building blocks, is delivered in the form of nasal sprays, and potentially functions as a “biological mask” with a thin shield
containment barrier in the nasal cavity. We are further developing certain aspects of our proprietary C&C hydrogel technology such
as the bioadhesion and prolonged retention at the nasal deposition site for intranasal delivery of drugs. We

Overview
We are an oncology therapeutics company applying advanced technologies to established tumor biology that are intended to efficiently deliver improved cancer treatments. We have deep experience in chemistry, formulation, and drug delivery, as well as research, clinical, and commercial pharmaceutical development, resulting in successfully taking product candidates from the clinic to approval, launch, and commercialization.
We recently entered into an intellectual property license agreement (the “WuXi License Agreement”) with WuXi Biologics (Shanghai FX) Co., Ltd. (“WuXi Biologics”) for the development and global commercialization of a portfolio of three next generation antibody drug conjugates (“ADCs”) targeting clinically validated, broadly overexpressed tumor antigens in high potential cancer indications with significant unmet need. The portfolio leverages an advanced ADC platform technology and are engineered for minimal off-target toxicity, greater stability and higher therapeutic index. We believe these assets can potentially overcome the limitations that hindered the first generation ADC therapies against these targets to deliver improved results for patients. Under the WuXi License Agreement, we have worldwide development and commercialization rights to all of our product candidates. We intend to develop each of our programs as a monotherapy and also in combination with other therapies. Read the annual filing ↗ PLRZ Material Annual filing released 2025-03-11 · GPT 6 Luna
The
T&T platform technology is designed to allow a long residence time and an intimate contact with the mucosal tissue for a targeted
delivery of medicines. We expect that our T&T platform product candidates will be regulated as a combination-product consisting of
a nasal sprayer and formulation consisting of a hydrogel and a generic API, which we intend to pursue under the FDA’s 505(b)(2)
pathway. We aim to conduct feasibility studies for our T&T platform product candidates with corticosteroids, benzodiazepines and
naloxone, beginning in the fourth quarter of 2024 through the first quarter of 2026. Pre-clinical studies will follow and are expected
to begin in the second quarter of 2026. Phase I clinical trials for the leading T&T technology product candidate are planned for
the fourth quarter of 2027. In
March 2025, we initiated preclinical studies in evaluating our T&T platform for the intranasal administration of Naloxone, an opioid
antagonist designed to rapidly reverse opioid overdose. These studies will assess key parameters, such as drug loading capacity, release
kinetics, nasal deposition and stability, laying the groundwork for further safety and efficacy testing in preclinical and clinical studies.
The study will be conducted in collaboration with Professor Fabio Sonvico, Associate Professor at the Department of Food and Drug of
the University of Parma (Italy) a leading expert in the development of intranasal and pulmonary drug delivery solutions and a member
of our Scientific Advisory Board.

much higher than the upper cell penetration limit, the polymers will simply lay on top of the cells and act as a physical barrier to
viruses and allergens from contacting the nasal epithelial tissue, as opposed to penetrating the cells and causing a chemical reaction.
Therefore, the C&C product candidates are not expected to be considered as drugs by the FDA but as medical devices.
Our
leading technologies are C&C and T&T. The C&C provides a barrier against a wide range of allergen particulates and viruses.

Both stocks start on the first shared trading day within the selected window. Unavailable metrics leave gaps.
Financials use SEC canonical statements available by the displayed cutoff, retaining each company's fiscal period end. Annual and quarterly amounts are shown separately. P/E is unavailable when earnings do not support a positive ratio.
Business overlap uses industry tags from annual filings released in 2025. Each core activity receives full weight; each material activity receives one quarter of that weight. Rarer industries carry more weight. We sum the smaller exposure for each shared activity and divide it by the sum of the larger exposure for every activity in either company. This measures business overlap, rather than price correlation or expected returns.
Search eligibility requires distinct issuers, a shared core category and at least 20% weighted overlap, supported by industry or sector evidence and specific business activities. Broad classifications require stronger overlap within the same sector. Comparisons also need at least 252 shared price observations within two years, recent trading and a common sourced revenue or net-income trend. Missing P/E or gross margin alone does not exclude a comparison. The eligibility snapshot refreshes daily. Related comparisons use a separate, stricter peer rule; their ten-peer discovery limit does not limit search eligibility. Other stock pairs remain available in the comparison tool.
