Ganfeborole Drug Asset Due Diligence Report 2026: Clinical, IP, Market, Deals, and Go/No-Go
This Ganfeborole Drug Asset Due Diligence Report was built with PatSnap Life Sciences MCP workflows. Drug & Asset MCP establishes identity, ownership and stage; Clinical Trials MCP checks design, endpoints and readouts; Company & Deal Intelligence MCP reconstructs transaction precedent. Explore the MCP servers used in this report.
Decision date: 16 September 2026. Currency fields are presented in US$ millions as returned by the deal dataset. This is a screening memorandum, not legal, medical, patent or investment advice.
Executive recommendation: CONDITIONAL GO
Decision memo
Advance with milestone-based economics while efficacy durability, safety differentiation, patent scope, and market positioning are validated.
The central underwriting question is whether Ganfeborole can convert its Small molecule drug profile and LeuRS biology into clinically meaningful differentiation while preserving an investable safety, IP and commercial position.
1. Asset identity and development status
| Asset | Ganfeborole (query alias: Ganfeborole) |
|---|---|
| Modality / target | Small molecule drug; LeuRS; LeuRS inhibitors |
| Highest global status | Phase 2 |
| Originator | GSK Plc, Anacor Pharmaceuticals LLC |
| Active developers | GSK Plc, Anacor Pharmaceuticals LLC |
The MCP disease footprint includes Tuberculosis, Pulmonary Tuberculosis. The highest-phase flag is a useful orientation point, but the licensing case depends on indication-level evidence and rights, not the global label alone.
2. Clinical program: design and endpoint audit
| Registry | Phase | Status | Enrollment | Lead primary endpoint |
|---|---|---|---|---|
| NCT07784894 | Phase 1 | Not yet recruiting | 28 | Primary endpoint not disclosed in English source |
| NCT07773610 | Phase 2 | Not yet recruiting | 135 | Primary endpoint not disclosed in English source |
| NCT06354257 | Phase 1 | Completed | 20 | Primary endpoint not disclosed in English source |
The trial set should be diligenced for randomization, comparator relevance, endpoint hierarchy, analysis population, multiplicity, geographic mix and readout timing. For early-stage studies, safety and dose selection can be as decision-critical as response rate.

3. Clinical readouts: what is known
A Phase 1, Open-label, Fixed Sequence, 1-way Drug-drug Interaction Study to Investigate the Pharmacokinetics of GSK3036656 and an Oral Contraceptive Containing Ethinyl Estradiol and Levonorgestrel When the Oral Contraceptive is Administered Alone and in Combination With GSK3036656 in Healthy Female Participants of Nonchildbearing Potential Aged 18-65 Years of Age
Phase 1; n=20; evaluation: Not stated in English source. Reported fields: EE, Day 1(Geometric Mean) = 627.11 hour*picogram per milliliter (h*pg/mL) ; EE, Day 15(Geometric Mean) = 552.01 hour*picogram per milliliter (h*pg/mL)
A Phase IIa Open-label Trial to Investigate the Early Bactericidal Activity, Safety and Tolerability of GSK3036656 in Participants With Drug-sensitive Pulmonary Tuberculosis
Phase 2; n=76; evaluation: Not stated in English source. Reported fields: Change in log10 Colony Forming Units (CFU) Per (/) Milliliter (mL) of Direct Respiratory Sputum Samples From Baseline to Day 14(Mean) = -0.199 Log10CFU/mL ; Change in log10 Colony Forming Units (CFU) Per (/) Milliliter (mL) of Direct Respiratory Sputum Samples From Baseline to Day 14(Mean) = -0.017 Log10CFU/mL
GSK announces positive Phase IIa study results for a new first-in-class candidate medicine for patients with tuberculosis
Phase 2; n=not disclosed; evaluation: Positive. Reported fields: Log10 CFU/mL in CFU = -0.138 log10CFU/mL (95%CI, -0.167 to -0.109)
These fields are structured evidence signals, not a substitute for statistical review. The next diligence pass should reconcile denominators, confidence intervals, follow-up, censoring, dose cohorts and treatment-emergent toxicity against the original abstract, registry and protocol.
4. Market and competitive position
Ganfeborole addresses Tuberculosis, Pulmonary Tuberculosis. Commercial attractiveness rests on addressable patients, treatment-line placement, duration, administration burden, pricing and displacement of entrenched standards. The modality—Small molecule drug—must demonstrate a benefit large enough to offset class-specific safety and operational costs.
The MCP screen returned 3 matched transaction record(s) under the scope “target-level comparable: LeuRS.” Partner activity is a market-validation signal, but it does not establish net present value.
5. Transaction precedent and economics
Transaction-scope note: No direct asset-specific transaction was returned. The table below shows target-level comparable: LeuRS records as comparable precedents only.
| Date | Transaction | Phase at deal | Disclosed economics |
|---|---|---|---|
| 2025-11-10 | AN2 Therapeutics Announces Research Collaboration With GSK to Advance Boron-Based LeuRS-Inhibitors Targeting Tuberculosis (TB) | Discovery | Financial terms not disclosed |
| 2022-03-25 | AN2 Therapeutics has raised $69 million from its IPO to fund a pivotal test of a novel antibiotic licensed from Pfizer | Phase 2 | Financial terms not disclosed |
| 2012-10-05 | GSK exercises option on Anacor’s novel antibiotic for the treatment of gram-negative infections | Not disclosed | US$15.0M upfront |
Headline values are not directly comparable. Diligence should normalize upfront cash, equity, development and sales milestones, tiered royalties, opt-in mechanics, cost sharing, change-of-control clauses and geography.
6. IP and freedom-to-operate screen
The milestone feed surfaced a patent-application signal described as “COMPUESTOS DE BENZOXABOROL Y USOS DE LOS MISMOS”. The milestone feed surfaced a patent-application signal described as “4 -substituted benzoxaborole compounds and uses thereof”. The milestone feed surfaced a patent-application signal described as “Boron-containing small molecules”.
The claim chart should separately test composition or sequence coverage, formulation and dosing, indication and biomarker claims, combinations, manufacturing know-how, prosecution history, term extensions and third-party blocking rights.
7. Principal risks and diligence gates
- Therapeutic index and off-target toxicity
- Resistance biology and biomarker-defined patient selection
- Differentiation from established and emerging standards
Cross-functional diligence should also test CMC comparability, supply chain, pharmacovigilance, regulatory correspondence, data integrity, investigator concentration, partner obligations and change-of-control restrictions.
8. Final go/no-go memorandum
CONDITIONAL GO
Advance with milestone-based economics while efficacy durability, safety differentiation, patent scope, and market positioning are validated.
Required pre-signing gates: reproduce key efficacy analyses; complete an indication-specific safety review; run a full patent-family and freedom-to-operate search; model risk-adjusted economics by territory; and reconcile all rights, sublicenses and encumbrances.
