1.         Introduction

 

XORTX Therapeutics Inc. (XORTX) is a biotechnology company with three drug development programs, two of which are clinically advanced products under development — XRx-008 for Autosomal Dominant Polycystic Kidney Disease (ADPKD), XRx-101 for Coronavirus / COVID-19 infection and XRx-225 for Type 2 Diabetic Nephropathy (T2DN). XORTX is working to advance its clinical development stage products — XRx-008 and XRx-101 - that target xanthine oxidase to inhibit production of uric acid.

 

The drug substance of interest in this proposal is Oxypurinol for the treatment of ADPKD and COVID-19. The molecule was previously formulated as a capsule and conditionally approved by the FDA. The innovator company never sought full approval. XORTX gained the rights to the drug and intends to file an NDA via the 505(b)(2) pathway for treatment of ADPKD in mid-2025.

 

The current drug formulations are based on powder filled capsules including an organic base (L-arginine) to increase the drug substance bioavailability which was a factor in the earlier application.

 

L-arginine is hygroscopic and exposure to moisture may adversely affect the manufacturability, stability and performance of the product. Therefore, exposure to excessive moisture and humidity will be avoided during development, manufacturing and storage of the product.

 

The intent of this proposal is to develop prototype, immediate release, capsule and tablet formulations with the following characteristics:

 

Each formulation will contain Oxypurinol (200 mg), L-arginine (600 mg), and other appropriate excipients

Use of appropriate excipients to facilitate product performance and manufacturability

Comparative dissolution profiles for existing formulation and the formulations being developed will be evaluated, apply f2 comparison if acceptable

Scalable to large-scale manufacturing.

 

The development work in this proposal will be conducted under non-GMP condition.

 

2.         Environmental, Health and Safety

 

The Environmental, Health and Safety (EH&S) requirements for handling the active pharmaceutical ingredient (API) was provided by client.

3.Analytical Method Transfer and Development

 

3.1Cleaning Assay by HPLC Transfer

 

A validated HPLC method for the API cleaning assay will be transferred to Covar to support cleaning qualification of equipment for the manufacture of oxypurinol products.

 

3.2Analytical Method Development

 

The following test methods will be developed for the present study

 

Content and related impurities assay for tablets and capsules by HPLC

 

It is assumed that the same dissolution method by HPLC for existing capsules will be suitable for use in the present study.

 

Phase appropriate method validation may be conduct upon request at additional cost.

 

The following compendial tests may be evaluated before testing

 

Appearance

ID by FTIR (ATR)

Disintegration

Loss on drying

 

4.API Characterisation

 

The following physical properties of oxypurinol drug substance will be studied:

 

Appearance

Flow properties by Flodex

Optical microscopy

Bulk and tap density (compressibility)

Particle size distribution by sieve analysis

Particle size distribution by laser diffraction if aggregates can be dispersed in water

Powder x-ray diffraction

Differential scanning calorimetry

 

5.Granulate Size Reduction

 

The API is expected to be supplied as an agglomerated material. Different granule size reduction approaches will be evaluated in the following order:

 

1. Granule size reduction by high shear mixing

 

Page | 4

Confidential

Document: QUO.XOR.002

 

Oxypurinol and L-arginine (mass ratio to be defined) will be mixed under different conditions in a conventional high shear granulator at different chopper speeds and time. The powder blend will be examined under an optical microscope after high shear mixing. Based on the results, a powder blend (after high shear mixing) will be dispersed in water to dissolve the L-arginine and the particle size distribution of the sheared drug substance will be determined by laser diffraction. The powder blend will also be filled into gelatin capsules and tested for dissolution (3 vessels)

 

2. Granule size reduction by sieving

 

Oxypurinol and L-arginine (mass ratio to be defined) will be blended (e.g. using a V-blender) and sieved (screen size to be defined). The sieved blend will be examined under the optical microscope and the particle size distribution of the API will be determined by laser diffraction. The dissolution profile of the powder blend after sieving will also be determined.

 

3. Milling in the presence of L-arginine or a suitable excipient

 

Milling trials will be conducted using a Quadro Comil U5, which is a milling equipment known to be scalable by design. The following strategies will be considered:

 

Milling of a mixture of API and excipient such as L-arginine or microcrystalline cellulose (e.g. Avicel PH102).

Milling of API and excipient such as L-arginine or microcrystalline cellulose using a screen with larger openings than that being used (screen with a openings of 150 micron). A multiple pass process may be considered and evaluated.

Milling of API alone at sub-ambient temperature may be considered. A low milling temperature may be maintained by addition of dry ice to the input milling material.

Milling of a mixture of API and excipient such as L-arginine or microcrystalline cellulose at sub-ambient temperature may be considered. A low mill temperature may be maintained by addition of dry ice to the input milling material.

 

In each milling trial, sufficient quantity of oxypurinol with or without L-arginine/excipient (mass ratio to be defined) will be blended (e.g. using a v-blender) and milled using the Quadro Comil (screen size 150 micron, except for multiple pass trials) for up to one hour. The temperature of the impeller will be monitored using an infrared thermometer during the milling process and the milling rate will be monitored online using a suitable balance.

 

A de-agglomeration method will be selected, and the de-agglomerated material will be examined by:

 

Appearance

Particle size distribution by laser diffraction

Optical microscopy

Powder X-ray diffraction (optional, non-GMP in-house or by third party)

Differential scanning calorimetry (DSC)

Assay and related impurities by HPLC

 

6.Excipient Compatibility (optional)

 

Preformulation data such as those collected from existing formulations and API characterisation will be studied. Excipient candidates will be proposed to client for the excipient compatibility study.

 

The following will be considered for potential excipients:

 

Degradation pathway and potential degradation pathway of the API

Moisture content and hygroscopicity

Compression behavior

Particle size distribution

Regulatory acceptance

Bioavailability impact

Supplier sourcing

 

Effort will be made to avoid excessive use of excipients to preserve the impact of L-arginine on the bioavailability of the drug substance.

 

Up to 10 powder blends of formulations will be prepared and compressed into round biconvex tablets (compression weight around 1000 mg) using a tabletop single-station (manual) compression machine. The samples will be packaged in 40mL HDPE bottle and induction sealed with and without desiccant. The packaged tablets will be stored at 25, 40 and 50°C. The 50°C samples will be evaluated using the following tests:

 

Appearance

Assay and impurities

Disintegration

 

Samples stored under other conditions will be tested if needed with additional cost.

 

Based on the excipient compatibility study results, a lead formulation and a backup formulation will be identified and tested for dissolution for further formulation development.

7.Development of Capsule Formulation

 

Based on the composition of the lead formulation from excipient compatibility study and/or existing formulation development data, up to five prototype capsules blends will be prepared and evaluated for the following properties:

 

Appearance before and after storage with and without desiccant

Flow properties by Flodex

Tap and bulk density

 

Based on the blend testing results, a lead blend and a backup capsule blend will identified for processability and physical stability, The lead formulation will be filled into white opaque size 00 elongated or 000 hard gelatin capsules using a manual encapsulation machine and tested for:

 

Appearance

Fill weight

Disintegration

Dissolution

 

8.Development of Tablet Formulation

 

Based on the composition of the lead capsule blend and background stability information from oxypurinol formulations, up to 6 prototype blends (about 500 g each) will be prepared. The composition of the prototype blends may be taken directly from those of the capsule blends. The prototype blends may also be prepared to evaluate to the effect of lubricant, disintegrant, and binder levels on their flow and compression properties.

 

The compression blends will be evaluated before compression for:

 

Appearance

Flow properties by Flodex

Bulk and tap densities

 

The compression blends will be compressed into tablets (of different tablet hardness) of plain biconvex capsule shaped tablets of 1 g or less. Plain, biconcave, capsule shape tooling will be used for tablet compression. It is assumed that the formulation blends will be directly compressible. Otherwise, a dry granulation method will be employed by slugging or by roller compaction using a tabletop roller compactor to be acquired by Covar a its own cost. At present, several used tabletop roller compactors is available for purchase in North America and for immediate delivery.

 

The formulations will be prepared using the following equipment

Based on the results, a suitable batch of tablets will be prepared at 1 kg scale. 500 g of the compressed tablets will be packaged in induction sealed (HDPE, 40 mL) bottles with and without desiccant and stored at 25°C ± 2°C / 60% ± 5% RH and 40°C ± 2°C / 75% ± 5% RH.

 

9.Tablet Film Coating (Optional)

 

About 250 g of the compressed tablets will be aqueous film coated using a moisture barrier coating composition, Opadry® amb II. An enhanced O’Hara pan coater (Labcoat M10, 8 inch perforated coating pan) will be used for the coating operation. The coated tablets will be evaluated for dissolution and packaged in induction sealed (HDPE, 40 mL) bottles with and without desiccant and stored at 25°C ± 2°C / 60% ± 5% RH and 40°C ± 2°C / 75% ± 5% RH, for further stability testing if required with additional cost.

 

10.Cleaning Qualification

 

Cleaning qualification campaign will be performed for the process training. The cleaning process is considered validated if three satisfactory cleaning verification is achieved using the same equipment.

 

11.Stability Assessment of Formulations

 

The package capsules and uncoated tablets packaged without desiccant will be tested in accordance with the following schedule:

 

Initial

2 wk, 1 and 3 months at 40°C ± 2°C / 75% ± 5% RH (accelerated condition)

2 wk, 1 and 3 months at 25°C ± 2°C / 60% ± 5% RH (long term condition; optional testing)
