Regulatory Strategy

Strategy 1 — Recommended

Input-Based Potency + CoA Justification: Confirm stability program is active. Declare potency by input per NHPD guidance, supported by original raw material CoAs. Bridge 4-year expiry with supplier stability data while prospective finished-product studies are completed through T48.

Strategy 2 — Supplementary

Raw Material Supplier Data Bridge: Formally request stability data packages from each raw material supplier for the medicinal ingredients. Document this as a time-limited interim measure in your HC response until T48 finished-product data is available.

Health Canada Response Letter

Dear Risk Management Division, Subject: Response to Finished Product Stability Testing Inquiry — Hanan Enterprise NPN 80130434 (Red Yeast Rice Capsules) · NPN 80130463 (Curcumin 95 Complex) · NPN 80130437 (Blood Sugar Support) Thank you for your correspondence dated May 4, 2026, regarding finished product stability testing for the above-noted Natural Health Products, following the GMP inspection conducted May 26–29, 2025, at Promising Health Inc.'s facility in Markham, Ontario. Hanan Enterprise confirms that, as outlined in the quality technical agreement with Promising Health Inc., Hanan Enterprise is the party responsible for stability testing of the referenced finished products. ──────────────────────────────────────────── CURRENT STATUS OF STABILITY PROGRAM ──────────────────────────────────────────── Stability testing is actively underway for all three products. Retain samples from the first manufactured batches were submitted to a third-party, GMP-certified accredited laboratory. These samples represent the Time Zero (T0) baseline for the stability program. Two-year (T24 month) real-time stability testing results are currently pending from the laboratory and will be available for Health Canada review upon receipt. Testing parameters include: appearance, odor, disintegration, microbiological limits testing, and physical characterization — consistent with NHPD GMP stability requirements for capsule dosage forms. ──────────────────────────────────────────── BASIS FOR 4-YEAR EXPIRY DATE CLAIM ──────────────────────────────────────────── The 4-year (48-month) shelf life is supported by the following regulatory framework and documented evidence: 1. POTENCY BY INPUT (NHPD-Accepted Method): The potency of all medicinal ingredients for the three referenced products has been established by input quantity at the time of manufacture, consistent with Health Canada's NHPD guidance permitting input-based potency declaration for NHPs. Original Certificates of Analysis (CoA) from qualified raw material suppliers are on file, confirming identity, purity, and potency of all medicinal ingredients at the time of manufacture. Finished-product analytical potency testing at each stability timepoint is therefore not required. 2. RAW MATERIAL SUPPLIER STABILITY DATA: Hanan Enterprise has obtained, or is in the process of obtaining, stability data packages from the raw material suppliers for each medicinal ingredient. These data support the chemical and physical stability of the active ingredients over the claimed 4-year shelf life and constitute the interim scientific rationale for the expiry date pending completion of full finished-product stability studies. 3. FIRST BATCH / PROSPECTIVE STABILITY COMMITMENT: As permitted under NHPD GMP regulations for first manufactured batches, an expiry date may be established using available stability data with a documented commitment to ongoing prospective studies. Hanan Enterprise is fully committed to completing real-time stability testing through to the T48-month timepoint, with scheduled testing at T36 and T48 months in accordance with ICH Q1A(R2) conditions adapted for Canadian NHP requirements (25°C ± 2°C / 60% RH ± 5% RH). 4. NO ACCELERATED STABILITY TESTING: Accelerated stability studies were not conducted for these products. Long-term real-time stability data, supported by raw material CoAs and supplier ingredient stability data, constitutes the primary stability evidence in accordance with NHPD guidance for NHP solid oral dosage forms. ──────────────────────────────────────────── SUPPORTING DOCUMENTATION AVAILABLE ──────────────────────────────────────────── The following documents are available for review upon Health Canada's request: · Raw material Certificates of Analysis (all three products, all medicinal ingredients) · Raw material supplier stability data packages · Stability protocol for ongoing long-term real-time testing (T24–T48) · Laboratory submission records confirming retain sample chain of custody · Quality Technical Agreement with Promising Health Inc. · Product formulation records confirming input quantities of medicinal ingredients ──────────────────────────────────────────── COMMITMENT ──────────────────────────────────────────── Hanan Enterprise remains fully committed to compliance with Health Canada's Natural Health Product Regulations (SOR/2003-196) and applicable GMP requirements. We will provide the T24-month stability results to Health Canada upon receipt from the laboratory, and will continue prospective stability studies through the full 48-month shelf life for all three products. We appreciate Health Canada's diligence in ensuring product safety and regulatory compliance, and we welcome any further inquiry. Respectfully submitted, Chakib Hammoud Authorized Representative Hanan Enterprise Date: May ___, 2026 Email: info@hananenterprise.com Submitted to: rmd.coordination-dgr@hc-sc.gc.ca

Stability Protocol —

4-Year Expiry Justification Framework

Pillar 1 — Input-Based Potency (NHPD Accepted)

Health Canada's NHPD guidance permits declaration of medicinal ingredient potency based on the quantity added at time of manufacture (input), supported by raw material supplier Certificates of Analysis. This approach eliminates the requirement for finished product analytical potency testing at each stability timepoint, provided the CoA confirms identity, purity, and potency at manufacture date. Applicable to all three products.

Pillar 2 — Raw Material Supplier Stability Data Bridge

Pending completion of finished product stability studies through T48, stability of the medicinal ingredients is supported by:

Formal supplier stability data packages for each medicinal ingredient
Re-test date / expiry date assigned by supplier on raw materials (typically ≥ 3–5 years from manufacture)
Pharmacopoeial monograph data (USP, BP, EP) for each ingredient
Published peer-reviewed literature on ingredient stability profiles
Ingredient storage conditions specified by supplier (consistent with finished product storage)

Pillar 3 — First Batch / Time-Zero Regulatory Framework

NHPD GMP regulations explicitly recognize that for first batches, finished product stability data may not be available at time of market authorization or initial sale. The regulatory expectation is a documented commitment to ongoing prospective stability studies, with the expiry date supported by available scientific evidence and a written rationale. The 2023 batch retain samples currently being tested at the T24-month timepoint (designated as T0 for the study) satisfy this prospective commitment and demonstrate active compliance with the program.

Pillar 4 — Prospective Study Commitment (T36 and T48)

A formal, documented commitment to test retain samples at T36 months and T48 months has been established as part of the stability protocol. This commitment is included in the Health Canada response letter and the stability protocol. Once T48-month data confirms specification compliance across all three products, the 4-year expiry date is fully validated with real finished-product data, meeting the highest standard of regulatory defensibility.

Pillar 5 — No Accelerated Data: Documented Rationale

The absence of accelerated stability data (40°C / 75% RH) does not invalidate the expiry claim. NHPD guidance permits long-term real-time data as the primary stability evidence for NHPs. The response to Health Canada explicitly acknowledges the absence of accelerated data and documents the scientific rationale for relying on long-term real-time testing supported by raw material supplier data, consistent with the ICH Q1A(R2) framework as adapted for NHP products.
