Mistral Nemo GCP Officer v1

A LoRA fine-tune of Mistral Nemo Instruct (12.2B) specialised in Good Clinical Practice (GCP) concepts, terminology, and regulatory guidance for clinical trials.

Model Description

This adapter was trained on a synthetic instruction-following dataset derived from GCP concepts and glossaries. The goal is to produce a model that can accurately explain, summarise, and reason about GCP principles — covering topics such as informed consent, investigator responsibilities, sponsor obligations, IRB/IEC oversight, essential documents, adverse event reporting, and ICH E6(R2) guidelines.

This is a LoRA adapter, not a standalone model. It must be loaded on top of the base model using PEFT.

Training Results

Epoch	Training Loss	Validation Loss
1	1.6238	1.5943
2	1.1876	1.5455

Validation loss decreased from epoch 1 to 2, with training loss continuing to drop. The gap between training and validation loss at epoch 2 suggests the model is approaching the useful limit for this dataset size.

Usage

Loading the adapter

from transformers import AutoTokenizer, AutoModelForCausalLM
from peft import PeftModel

base_model_id = "mistralai/Mistral-Nemo-Instruct-2407"
adapter_id = "NvMayMay/mistral-nemo-GCP-officerv1"

tokenizer = AutoTokenizer.from_pretrained(base_model_id)
model = AutoModelForCausalLM.from_pretrained(
    base_model_id,
    torch_dtype="bfloat16",
    device_map="auto",
)
model = PeftModel.from_pretrained(model, adapter_id)

Inference

prompt = "Instruction: What are the primary responsibilities of a clinical trial sponsor under ICH E6(R2)?\nOutput:"

inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=512, temperature=0.7, do_sample=True)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Intended Use

• Educational tool for learning GCP concepts and clinical trial regulations
• Rapid look-up and explanation of GCP terminology
• Drafting study-level summaries of regulatory obligations
• Supporting training material development for clinical research staff

Limitations

• Small training set (815 examples): The model may not cover edge cases or nuanced regulatory scenarios
• Synthetic data only: Responses have not been validated against primary regulatory source documents
• Not a regulatory authority: Outputs should not be treated as legal or regulatory advice — always verify against the official ICH E6(R2) guideline and applicable local regulations
• Validation loss plateau: The train/eval loss gap at epoch 2 suggests limited headroom without additional data
• English only
