Clinically Validated Pathology-based AI Prediction of Remdesivir-specific Post-treatment Rebound of SARS-CoV-2

SWITZERLAND, THURSDAY, 30 APRIL 2020 13:10 PM CET

As the world’s first AI-biopharma company that has discovered and publicized the precise aetiology and pathology of COVID-19¹, we are committed to the non-profit dissemination of our COVID-19 discoveries and the public validation of our COVID-19 clinical predictions.

Although remdesivir was almost universally believed as the most promising curative treatment candidate for COVID-19 based on strong compassionate use data² and in vitro data³ published in January 2020, we announced a contrarian pathology-based clinical prediction on 23 February 2020 that remdesivir would be an effective but non-curative treatment for severely ill COVID-19 patients and remdesivir would present the clinical risk of post-treatment viral rebound:

On 29 April 2020, the results of the world’s first clinical trial of remdesivir for severely ill COVID-19 patients, “Remdesivir in adults with severe COVID-19: a randomised, double-blind, placebo-controlled, multicentre trial”⁵, was published in the Lancet. This trial adopted a rigorously designed protocol with one of the strictest primary endpoints and participation criteria and analyzed the data collected from 236 severely ill patients in the intention-to-treat population.

As remdesivir’s mechanism of action is to inhibit RNA replicase without which SARS-CoV-2 cannot replicate in host cells, the efficacy of remdesivir as a treatment for COVID-19 largely depends on its efficacy on inhibiting viral load. Therefore, multiple-site specimens from all the 236 severely patients were collected on both in-treatment days (days 1, 3, 5, 7 and 10) and out-of-treatment days (days 14, 21 and 28) to evaluate remdesivir’s effect on viral load by quantitative PCR⁵:

Despite different sites of viral specimens as shown in Figure 3⁵, the out-of-treatment viral load significantly rebounded compared with the placebo group on days 21 and 28, though the in-treatment viral load numerically reduced compared with the placebo group on days 5 and 7.

Despite different times of remdesivir treatments as shown in Figure S6⁵, the out-of-treatment viral load significantly rebounded compared with the placebo group on days 21 and 28, though the in-treatment viral load numerically reduced compared with the placebo group on days 5 and 7.

Therefore, this human clinical trial data have robustly validated our contrarian prediction that post-treatment viral rebound is a remdesivir-specific clinical risk for severely ill COVID-19 patients no matter when to start the treatment and where to collect the specimen.

The clinical trial data further demonstrate that AI-based disease modelling and clinical predictions can deliver much better predictive power and explanatory power than conventional approaches for novel diseases with limited clinical data and short response timeframes.

As much as it is disappointing to see that remdesivir had exhibited the most potent antiviral efficacy in cell lines but failed to show clinically meaningful antiviral efficacy in human patients, it is alarming to know that the biased mechanism of action of remdesivir that targets only viral replication is a mismatch to the unbiased mechanism of action of SARS-CoV-2 that balances viral replication and viral spread, as we have predicted and published since 7 March 2020⁶:

Therefore, the rational discovery of unbiased COVID-19 treatments and vaccines that target the exact mechanisms of SARS-CoV-2 for both viral replication and host immunomodulation may be the only effective means to put an end to the COVID-19 pandemic.

To that end, Demiurge is also the world's first company that has discovered the complete set of unbiased prophylactic and therapeutic treatments for COVID-19:

1. Irinotecan + etoposide as a specialized treatment for critically ill patients (ongoing phase 2 clinical trial NCT04356690).
2. PI3K inhibitors as a curative treatment for moderately-to-severely ill patients (ongoing in vitro study).
3. Non-S-viral-protein optimal target for a broad-spectrum vaccine for the healthy population (ongoing early-stage development).

About Demiurge Technologies AG

Demiurge Technologies is a research-based AI-biopharmaceutical company that transforms publicly available life science data into precise disease models in areas with unmet medical needs. The company pioneers a self-correcting scientific approach that validates disease models with the accuracy of AI-based predictions of phase 3 clinical trial outcomes. The company also pioneers a self-sustaining business that commercializes disease models by accelerating the AI-based discovery and development of innovative medicines. Demiurge started in 2016 with headquarters in Switzerland.

AI has been an emerging powerful approach to deeper disease understanding and faster drug discovery, yet it must be put to the most rigorous test to prove its worth under public scrutiny. Demiurge has predicted the outcomes of more than 90 phase 3 clinical trials across multiple therapeutic areas and achieved more than 80% accuracy. Furthermore, we have been inviting the public to witness our future predictions of clinical trial outcomes on Twitter (@DemiurgeTech).

Therefore, we officially put forward AI-based discoveries of the complete aetiology and pathology of COVID-19 and the candidate treatments for COVID-19 as scientific hypotheses only and invite the world to validate their potential to solve the unprecedented global crisis posed by COVID-19.
