The emergence of Khartis Therapeutics with $95 million in total disclosed funding provides a useful benchmark for tracking capital flowing into oral small-molecule immunology companies in 2026.
Khartis announced a $50 million Series B in August 2026, bringing its cumulative financing to $95 million. The company is developing oral small-molecule medicines for immune-mediated and chronic diseases, led by an oral selective IGF-1R inhibitor for thyroid eye disease.
InduPro's $77 million Series B adds another substantial data point. However, it is important to qualify the comparison: InduPro is a broader proximity-biology company whose pipeline spans oncology and immunology, rather than a pure-play oral small-molecule immunology biotech.
Taken together, the two companies represent $172 million of disclosed 2026 financing capital, making them a useful starting benchmark for examining investor appetite for next-generation therapeutic platforms with immunology exposure.
The $172 Million Starting Benchmark
The headline calculation is straightforward:
Company
2026 Disclosed Financing
Strategic Focus
Khartis Therapeutics
$95M cumulative funding
Oral small-molecule immunology
InduPro
$77M Series B
Proximity therapeutics; oncology & immunology
Combined benchmark
$172M
Immunology-related emerging platforms
Khartis' $95 million represents total capital raised, not necessarily $95 million raised during 2026. Its latest financing was a $50 million Series B.
InduPro's $77 million is specifically a 2026 Series B financing.
That distinction matters when building a true 2026 capital-flow dataset.
#1 — Khartis: The Clearest Pure-Play Benchmark
Khartis is the stronger fit for the specific theme of oral small-molecule immunology.
The company describes itself as developing first- and best-in-class oral small-molecule medicines for immunological and chronic diseases. Its lead program is an oral selective IGF-1R inhibitor for thyroid eye disease.
Its financing profile includes:
$50M Series B in August 2026
$95M total capital raised
Forge Life Science Partners as Series B lead
Participation from Longwood Fund and Alexandria Venture Investments
Existing backing from Foresite Capital, Lilly Asia Ventures and Nextech Invest
For investors tracking oral immunology, Khartis is therefore a particularly clean benchmark.
#2 — InduPro: A Broader Platform With Immunology Exposure
InduPro's $77 million Series B is also significant, but its strategic profile is different.
The company is building a proximity-biology platform that uses surface-protein neighborhoods to identify new therapeutic targets and combinations.
Its pipeline includes:
Oncology programs
Immuno-oncology programs
Autoimmune programs
The company specifically describes IDP-003 as a bispecific PD1 agonist for autoimmune disease, while other programs focus on oncology.
That means InduPro should be included in a broad immunology-related capital tracker, but separated from pure oral-small-molecule companies.
Why the $172 Million Figure Needs Careful Interpretation
The $172 million number is useful, but it should not be described as $172 million of pure 2026 oral-small-molecule immunology financing.
There are three reasons.
1. Khartis' $95M Is Cumulative
The company raised $50 million in its latest Series B, bringing total financing to $95 million.
2. InduPro Is Not Purely Immunology
Its platform spans oncology, immuno-oncology and autoimmune programs.
3. InduPro's Platform Is Not an Oral Small-Molecule Program
Its lead clinical program is a proximity-based bispecific antibody-drug conjugate, while its immunology programs are also biologic modalities.
Therefore, $172 million is best treated as a starting benchmark for immunology-related emerging biotech platforms, not a definitive 2026 total for oral small-molecule immunology.
Khartis' strategy fits this model by combining an established immunology pathway with an oral small-molecule approach.
The Thyroid Eye Disease Opportunity
Khartis' lead program targets thyroid eye disease (TED).
The company is developing an oral selective IGF-1R inhibitor specifically for the condition.
That is strategically interesting because TED is a defined specialty indication where an oral therapy could potentially differentiate itself through administration convenience.
For investors, the important question will be whether an oral approach can provide a sufficiently attractive balance of:
Efficacy
Safety
Convenience
Dosing
Patient persistence
Commercial cost
Capital Intensity Is Also an Intelligence Signal
The $50 million Khartis Series B and $77 million InduPro Series B demonstrate that investors remain willing to provide substantial private capital to biotechnology platforms entering or approaching clinical development.
InduPro's financing was announced alongside the dosing of the first patient in its Phase 1 study.
That suggests investors are willing to finance companies around important development inflection points rather than waiting exclusively for later-stage clinical validation.
Big Pharma Participation Raises the Signal
InduPro's financing is particularly notable because its investor syndicate includes Merck's MRL Ventures Fund, Sanofi and Eli Lilly, alongside specialist investors.
That creates an important distinction between ordinary venture financing and strategic pharmaceutical participation.
Corporate venture investment can indicate that major drugmakers want exposure to:
New therapeutic platforms
Emerging target biology
Potential licensing opportunities
Future acquisition candidates
Competitive scientific intelligence
InduPro also has a separate licensing relationship with Lonza for ADC technologies supporting its oncology programs.
The Broader Capital-Flow Question
The real intelligence opportunity is to build a larger 2026 dataset.
Companies should be categorized according to:
Therapeutic Area
Autoimmune
Inflammatory disease
Immunology
Oncology
Rare disease
Modality
Oral small molecule
Injectable small molecule
Antibody
Bispecific
ADC
Cell therapy
Gene therapy
Development Stage
Discovery
Preclinical
IND-enabling
Phase 1
Phase 2
Phase 3
Financing Stage
Seed
Series A
Series B
Series C+
Strategic financing
This approach would prevent fundamentally different biotech businesses from being treated as equivalent.
Competitive Intelligence Benchmark
A useful 2026 tracker could therefore separate three categories:
Category
Benchmark Example
2026 Signal
Pure oral small-molecule immunology
Khartis
$50M latest round / $95M cumulative
Immunology + broader platform
InduPro
$77M Series B
Combined disclosed benchmark
Khartis + InduPro
$172M
The $172 million figure should be presented as a starting benchmark rather than a complete market total.
The eventual intelligence value will come from adding every qualifying 2026 financing and removing double-counting of cumulative capital.
What Investors Should Watch Next
The most important indicators are likely to be:
1. Additional Series B and C Financings
These provide the clearest evidence of sustained investor appetite.
2. Oral Immunology Programs Entering the Clinic
Clinical entry can materially change valuation expectations.
3. Big Pharma Participation
Strategic investors can provide an important signal of platform attractiveness.
4. Licensing Deals
Large partnerships can demonstrate that capital markets interest is translating into pharmaceutical demand.
5. Clinical Readouts
Ultimately, clinical efficacy and safety will determine whether today's financing enthusiasm is justified.
Implications for Pharmaceutical Business Development
For large pharmaceutical companies, the financing activity highlights a potentially attractive strategy:
This can be more capital-efficient than acquiring a company outright before its therapeutic platform has been validated.
The presence of multiple Big Pharma investors in InduPro's Series B illustrates how this strategy can operate through syndicates.
Implications for Biotech Investors
For private investors, Khartis and InduPro illustrate two different ways to capture immunology-related value.
Khartis: A focused therapeutic strategy built around oral small molecules and a clinically validated immunology pathway.
InduPro: A broader platform strategy using proximity biology across oncology and immunology.
The comparison highlights an important investment distinction:
focused asset risk versus platform optionality.
Limitations of the Benchmark
The $172 million figure should not be extrapolated into a market-wide 2026 capital total.
A rigorous market calculation would need to account for:
Undisclosed financing rounds
Cumulative versus current-year funding
Companies with mixed therapeutic pipelines
Companies whose lead assets are not oral
Private strategic investments without disclosed amounts
Venture debt
Licensing payments
Acquisitions
For this reason, the current figure is best described as a disclosed-company benchmark.
Looking Ahead
Khartis' $95 million cumulative funding and InduPro's $77 million Series B create a useful $172 million starting benchmark for tracking capital flowing toward emerging biotech platforms with meaningful immunology exposure in 2026.
But the data becomes more interesting when the companies are separated by modality.
Khartis is the clearer pure-play example: an oral small-molecule company focused on immunological and chronic diseases. InduPro is broader, combining oncology and immunology with proximity-based biologic approaches.
The next step for market intelligence teams is therefore to expand the dataset and determine how much of 2026's biotech capital is actually flowing into oral small-molecule immunology, rather than simply immunology-related biotechnology.
That distinction could reveal whether investors are specifically returning to oral drug platforms—or whether the apparent capital surge is primarily being driven by broader enthusiasm for validated immunology biology and differentiated therapeutic platforms.
Key Takeaways
Khartis has raised $95 million cumulatively, including a $50 million Series B announced in August 2026.
InduPro raised $77 million in Series B financing in August 2026.
Together, the companies provide a $172 million disclosed benchmark for immunology-related emerging biotech platforms.
Khartis is the stronger pure-play example for oral small-molecule immunology.
InduPro has a broader oncology and immunology platform and should not be classified as a pure oral-small-molecule company.
The $172 million figure should not be presented as the total 2026 market capital flow because Khartis' figure is cumulative.
Big Pharma participation in InduPro's round adds a strategic-investment dimension to the capital-flow signal.
A larger 2026 financing database should separate therapeutic area, modality, development stage, and financing type.
