Executive Summary

A clinical-stage biotech pioneering first-in-class biologic agents to treat cancer

  • Nerofe is a first-in-class drug that flips immune-suppressed tumors into immune-active ones — turning the body’s own defenses against the cancer, without chemo-style toxicity.
  • Validated in multiple preclinical studies and two independent human trials; measurable responses in late-stage AML and solid-tumor biopsies.
  • ISK is now raising $18M to take Nerofe to Phase 2b trials — unlocking the next growth inflection point and securing a path to a $1B+ exit.

A once-in-a-lifetime opportunity to back a genuinely novel oncology company with strong clinical proof in heavily pretreated patients, and a pathway to one FDA approval across multiple cancers.

The Challenge

~40% of people will be diagnosed with cancer in their lifetime

The treatment still hasn't caught up.

Source: American Cancer Society — 1 in 2 men, 1 in 3 women will be diagnosed with cancer in their lifetime.

Chemotherapy

Standard of care since 1960

Poisons every dividing cell — cancer and healthy ones (hair, gut lining, bone marrow).

The gap

Severe toxicity; 50% of patients can't tolerate the needed dose.

Immunotherapy

Activates your immune system to fight cancer

Removes a brake on existing T-cells so they can attack cancer — but only works if immune cells are already at the tumor.

The gap

Effective for 10–15% of patients (can't help in cold tumors where immune cells are not present).

Targeted therapy

Tailored to specific cancer mutations

Custom-made antibodies designed to find one specific marker on cancer cells.

The gap

Each drug works for one mutation only, resistance develops in months.

Our Innovation

ISK is pioneering a paradigm shift in therapeutics development

ISK is the first to target the ST2 receptor in clinical trials for cancer.

ST2 is a receptor over-expressed by a large subset of cancer cells across many tumor types, helping to suppress the immune response.

For decades, ST2 has been studied for asthma & heart disease, but no approved cancer drug has ever targeted it — until now.

Our novel peptide Nerofe binds the ST2 receptor to directly kill cancer cells while reactivating anti-tumor immunity — all while meeting robust efficacy and safety standards.

Our Solution

Introducing Nerofe: a first-in-class therapeutic for solid and liquid tumors

First-in-class ST2 inhibitor

Nerofe is a stabilized 14-amino-acid peptide derived from Tumor-Cell Apoptosis Factor (TCApF), a hormone naturally produced in the human thymus.

Direct immune activation

Nerofe activates anti-cancer immune response through binding to the ST2 receptor on innate immune cells and CD8 T-cells.

Tumor-agnostic potential

Robust preclinical data demonstrates efficacy across a broad range of tumors — AML, breast, glioblastoma, mCRC, pancreatic cancer, neuroblastoma, lung and prostate.

Born from a proprietary platform

Nerofe is the first of 20+ novel hormones identified by a proteogenomic engine (physics + AI) that mines the 95% of the human genome inaccessible to conventional drug discovery.

Note: the proteogenomic engine platform beyond Nerofe is not part of this offering.

How The Process Works

A novel mechanism of action to destroy cancer cells

01

Nerofe enters the tumor cells through the ST2 receptor.

Nerofe enters the tumor cells through the ST2 receptor.
02

Nerofe reaches the Golgi Apparatus and induces its destruction.

03

Due to the destruction of the Golgi, proteins accumulate in the ER leading to ER stress and activation of the ER stress repair mechanism.

04

The ER stress repair mechanism is inhibited by Nerofe's downregulation of sXBP1.

Cell death is caused by unrepaired ER stress.
01

The first to change genetic characteristics of tumor cells — it causes the shut down of expression of IL10 and induction of IL2 gene and protien

02

Achieves downregulation of KRAS, reducing the most common cancer-driving mutation directly inside tumor cells

03

Favorable safety profile, with zero dose-limiting toxicities in early studies

Addressable Market

$32B+ market opportunity, unlocked by a single FDA approval

2030

All listed cancers express ST2 — allowing ISK to pursue one approval covering every ST2+ tumor instead of applying cancer-by-cancer (Keytruda / MSI-H and larotrectinib / NTRK+ as precedents).

The Market Trusts In Us

Nerofe is recognized by world-class professionals and industry leaders as a breakthrough innovation

There is a signal here worth discovering. Nerofe is a novel class of agent that induces apoptosis of leukemic blasts but appears to also function as an immune-targeted therapy at a genomic level. We had 1 notable patient with R/R CMML-2 where blasts were reduced to less than 5%. Two other R/R AML patients with an initial life expectancy of 8 weeks stayed on trial for over a year. I strongly believe that this novel compound needs to be further explored.

Justin M. Watts, MD
Section Chief Leukemia, University of Miami Sylvester

We have treated 12 patients… Changes in the tumor immune microenvironment highlight potential synergy with immune checkpoint blockade. We are optimistic that combining NEROFE and doxorubicin with an anti-PD1 monoclonal antibody will lead to durable clinical responses. We are in active discussions with pharmaceutical companies to start an investigator-initiated clinical trial of NEROFE, doxorubicin, & anti-PD1 antibody.

Benjamin A. Weinberg, MD
Associate Professor, Lombardi Comprehensive Cancer Center, Georgetown

Nerofe is a very novel peptide with mechanisms of action different from any other molecules I'm aware of in the Alzheimer's field. Its preclinical data to date suggest high potential in AD and related neurodegenerative diseases. Nerofe is near the top of our list of candidates we would like to investigate.

Every current cancer treatment is a trade-off between breadth and selectivity

Nerofe is the only approach positioned in the top-right: broad, cross-indication reach with tumor-cell selectivity, because it targets a receptor rather than a single mutation.
