Why CohortBid? Resolving Clinical Operations Failure Rates
Traditional site selection processes are broken, slow, and non-transparent. CohortBid introduces a competitive, data-verified marketplace that reduces timelines by up to 70%.
THE STATUS QUO

The Cost of Traditional Feasibility

40%
Site Dropout Rates

Nearly half of all selected clinical sites fail to enroll a single patient, necessitating emergency site rescue.

80%
Trial Timeline Delays

Eight out of ten clinical trials face timeline extensions due to inaccurate investigator feasibility projections.

12w
Average Site Activation Cycle

Paper CDAs and manual emails drag out the Site Selection Visit (SSV) cycles to over 3 months per protocol.

THE COHORTBID ADVANTAGE

Pioneering Predictable Enrollment

98%
Patient Cohort Accuracy

Investigators submit live registry snapshots verified by CTRI history, drastically reducing zero-enrollment sites.

70%
Reduction in Site Setup Cycle

Consolidated digital workflows (21 CFR Part 11 CDAs and multi-step digital FQs) select sites in days.

100%
CDSCO & IEC Traceability

Real-time matching of CDSCO numbers ensures investigators hold valid Ethics Committee clearances.

2

Sites discover and bid

Investigators browse listings matched to their specialty and submit an Expression of Interest — patient cohort data, trial experience, and site capability.

3

CDA signed digitally

Shortlisted sites sign a digital CDA. Protocol details are unlocked. 21 CFR Part 11 compliant e-signature with full audit trail — no paper.

4

FQ → Site selected

Sites complete Basic FQ and Protocol FQ online. Sponsor scores, shortlists, and generates a sponsor-ready PDF report. Sites confirmed.

Frequently Asked Questions

Everything you need to know about the CohortBid clinical operations portal.

Is there any cost for investigators to register on CohortBid? +

No, registration and profile listing are completely free for clinical trial sites and Site Management Organisations (SMOs). Sponsors fund the marketplace operations via protocol publication and analytics service access.

How is clinical site data protected under DPDPA 2023 guidelines? +

CohortBid is built in strict compliance with the Digital Personal Data Protection Act (DPDPA) 2023. Site-level parameters (Ethics Committee registries, bed counts, CRC contacts) are fully encrypted and only visible to Sponsors once the Investigator signs a mutual CDA and clicks "Share Profile" for a specific trial invitation.

Does CohortBid execute electronic CDAs in compliance with international rules? +

Yes. All electronic signatures and document vaults are fully compliant with USFDA 21 CFR Part 11 and Indian Information Technology (IT) Act, 2000. Every signed CDA generates a unique cryptographic audit log containing IP coordinates, email validation hashes, and date-time stamps.

How does the local database match with ClinicalTrials.gov and CTRI registry results? +

Sponsor searches run parallel queries against local CDSCO registries and live APIs from ClinicalTrials.gov and Clinical Trials Registry - India (CTRI). When matches are found in the global registries, sponsors can shortlist them to import the registry parameters directly into the local database workspace.
